The 10% glucose solution will become less concentrated whereas the 5% solution will become more concentrated.

There are two glucose solutions having different amount of glucose in it which is separated from each other by a differentially permeable membrane. Through this membrane, glucose can not pass through it but water can diffuse through it due to its smaller size. Therefore, the water will diffuse from the 5% glucose solution toward the 10% glucose solution.

So less water is present at 5% solution after diffusion which make it more concentrated while on the other hand, 10% solution will become less concentrated as water will enter into it so we can conclude that 10% glucose solution will become less concentrated whereas the 5% solution will become more concentrated.

Thus, this could be the answer.

Answer:

Diagram D

Explanation:

When electrons absorb energy, they move to higher orbital levels. The highest energy levels are the furthest from the nucleus. More energy is needed to occupy higher energy levels. Therefore, the electron which must have absorbed the most energy is in Diagram D. In this diagram, the electron absorbs enough energy to move it from n = 1 to n = 4.

When electrons absorb energy, they move to higher energy levels. In the given question, option D shows maximum energy absorption as electrons move from n = 1 to n = 4. Thus, the correct option is D.

Electron transition is the transition of an electron from one energy level to another within an atom or artificial atom. In this, the electron "jumps" from one energy level to another, typically in a few nanoseconds or less. This transition is favored by the difference in energy in different energy levels.

When an electron absorbs energy, they move to higher energy orbital levels. The highest energy levels are the ones farthest from the nucleus and the lowest energy levels are the ones that are nearest to the nucleus. As more energy is required to stay at higher energy levels. Therefore, the electron must absorb the most energy.

In this diagram, option D denotes the highest energy photon as the electron absorbs enough energy to move from n = 1 to n = 4.

Therefore, the correct option is D.

Answer:42%

Explanation:

The percentage of the population is heterozygous for this gene is 42%. The correct option is C.

According to the Hardy-Weinberg equilibrium, if no unfavourable influences exist, genetic variation in a population will remain stable from one generation to the next.

Calculating the genetic diversity of a population at equilibrium can be done using the Hardy-Weinberg equation. A fundamental idea in population genetics that G. H. Hardy and Wilhelm Weinberg separately described in 1908 is now known as the Hardy-Weinberg equation.

The importance of the Hardy-Weinberg law is that it provides a way to assess how accurately a population's genetic makeup has changed over time. We could only determine if the population was in Hardy-Weinberg equilibrium with the genetic makeup.

We know that,

[tex]p^2+2pq+q^2=1[/tex]

Here,

p = 0.70

q = 0.30

So,

[tex](0.70)^2+2pq+(0.30)^2=1[/tex]

2pq = 42%

Thus, the correct option is C.

Answer:

Approximately 4.5 billion years ago (The Hadean Eon) .

Explanation:

The Geologic Timescale's "Hadean" era, named for Hades (Hell, well, we weren't feeling very imaginative that day), encompasses the Earth's origins. According to the evidence we currently have, the Earth's surface at that time was mostly made up of lava lakes and molten rock.

How would that appear? The first 500 Ma of Earth's history have left very little stuff behind. You may, however, take a peek at our moon, which similarly went through a lava lake period before freezing. You'll see that it has both dark and bright landscape.

The lighter material is known as highlands and is primarily composed of anorthosite. Anorthose, a kind of plagioclase feldspar, is the main component of the igneous rock known as anorthosite. According to what we know, the Moon too had a lava lake era. Liquid rocks exposed at the surface were cooling and fractionally crystallizing throughout this lengthy period. A certain order of minerals was developing. And these minerals were dividing up according to the density of the melt; less dense minerals, like plagioclase (Anorthose is a plagioclase), floated to the surface in a sort of incandescent crystal slush slurry and formed a sort of lid there. Denser minerals, like olivines, were sinking to the bottom of the lava lake to form cumulates. As the lava lakes cooled, anorthosite piled on top in successive layers, thickening the mass of floating crystals. Large meteor impacts occasionally pierced this anorthosite crust, and part of the thicker (and darker) underlying liquid accumulated in the ensuing craters to produce those roundish dark patches (Maria), which are now filled with basalt.

After the lava lakes froze/crystallized over, such characteristics were maintained since there was no significant tectonic activity on the Moon (except for the local meteor impacts which screw things up a bit).

The four macronutrients which are most important for the proper functioning of your body are as follows:

Macronutrients may be defined as the nourishing elements of food that the body requirements for energy and to possess the body's structure and functional systems.

Carbohydrates are the main source of energy for the body. It fuels your brain in the form of glycogen, kidneys, central nervous system, heart muscles, and all other various body parts and structures via glucose.

Proteins are required for the optimal growth and development of an individual. It also assists in the repair of the injured or damaged cells into newly synthesized ones.

Fats are the class of macronutrients that are the chief source of fatty acids that cannot be synthesized by our body itself. The components of fats such as cholesterol, triglycerides, etc accumulate energy, protect us, and safeguard our necessary organs.

Water is an ultimate requirement of each and every organism. It serves as a lubricant, relieves constipation, and removes impurities out of the body via urine, sweat, etc.

Therefore, it is well described above.

1) DNA Template strand: TACAATCGACCCATC. 2) Anticodon: AAU. 3) mRNA carries genetic information to build the protein. 4) 5 amino acids. 5) Amino acids: Met, Leu, Ala, Gly, Tyr.

1)

When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments:

The template strand is the one that is going to be complemented by the mRNA.

mRNA ⇒ AUGUUAGCUGGGUAG

  DNA ⇒ TACAATCGACCCATC

Remember that pairs are as follows

DNA    RNA

T     →    A

A     →    U

G     →    C

C     →    G  

2)

The anticodon is the sequence of three nucleotides that couples with the mRNA codon.

Each tRNA has two important sites. One of them is the anticodon that couples with the codon of the mRNA molecule. The other one carries the amino acid that is going to be addeded to the protein.

                              1st      2nd     3th     4th   5th

mRNA codons ⇒ AUG   UUA   GCU  GGG  UAG

tRNA anticodon ⇒         AAU

3)

Translation is the stage of protein synthesis during which mRNA carries genetic information needed to synthesize the new protein in the cytoplasm.

Steps,

1- The formed mRNA moves to the cytoplasm through the nucleus membrane pores.

2- Once in the cytoplasm, mRNA meets a ribosome, the primary structure for protein synthesis.

3- Ribosomes are organelles composed of the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.

4- While the ribosome reads mRNA strain from its 5' extreme to 3', tRNA adds the correct amino acids to build the polypeptide.

The function of mRNA during translation is to take genetic information needed to build the protein.

4)

Each codon codes for only one amino acid.

There are cases in which different codons code for the same amino acid, but a single codon always codes for one amino acid.

mRNA codons ⇒ AUG   UUA   GCU  GGG  UAG

Amino acids     ⇒ Met    Leu     Ala     Gly    Tyr

                                 1        2         3        4        5

Consider a block that is resting in between two springs (there is a dampener for those that care, so just go with it). The compressed side will push back if the block is pushed to either side, whereas the stretched side will pull back into the resting position. Once set free, they will oscillate until they are at rest again. However, the springs will ultimately alter and their resting position will alter if you consistently lean to one side.

The parasympathetic nervous system slows you down, absorbs and stores resources, repairs damage, and resists environmental demands for change. It is one of your two autonomic nervous system springs. You move faster thanks to the sympathetic system, which also releases energy and resources in response to environmental demands for change.

Your brain rapidly causes the adrenalin glands to release epinephrine and norepinephrine, which boost the sympathetic nervous system, when a threat or stressor is present. Your SS outweighs the PS, just like the springs. You actually go through the fight-or-flight reaction. Elevated heart rate, blood pressure, respiratory rate, glycogen breakdown, and changes in blood and air flow all work to get the body and brain ready to work at their best. Your senses become more acute, your eyes enlarge to improve your ability to see in the dark and detect movement, and the only exocrine process that is unaffected is perspiration. Acute stress causes this type of stress response, which reduces appetite.

Your systems must work very hard in this state, though. It gives you the motivation to either remove the threat or flee from it in a life-or-death emergency. Your springs will rebound once the threat has passed. As your PS pushes past the balance, there is a "lashback" of fatigue and sleepiness. Your body then attempts to return to homeostasis. You experience your post-workout munchies at this time.

However, the fight or flight response slows down to prolong the heightened wakefulness in cases of persistent stress. The stress reaction also includes the release of corticosteroids. These hormones enable you to respond in brief stressful situations. They flood the circulation with enormous amounts of glucose and fatty acids. However, these stress hormones accumulate and persist in chronic stress. This causes a rise in appetite and a yearning for salt, sugar, and fats. components that stress depletes but are crucial.

The balance becomes dysfunctional in this situation. Individual balances are out of whack, but they nonetheless exert a similar amount of effect. The psychological aspects of this imbalance frequently play a role. You may feel more hungry and be less active mentally if you are trying to escape the tension. Fighting may cause you to spend all of your energy on cerebral activities rather than other bodily processes like digestion, which will make you feel less hungry. You normally enter significant depression area if you chance to encounter the freeze response, which occurs when there is no way that you can conceive of to flee or defend yourself. Because to freeze is to completely lose all hope when one is entrapped and outnumbered.

Chronic stress causes tolerances and sensitivities, which have a tendency to reinforce one another and make it more difficult to reverse the situation. This typically makes the mental condition worse, which feeds the cycle.

Fun fact: fear can actually cause death. However, it isn't fear that kills them. The strong PS reaction is what causes your heart to stop beating. The stress of losing a life partner, sometimes known as sadness, is another reason why an elderly widow or widower will degenerate and pass away suddenly not long after the loss.

Answer: Stress may negatively impact someone’s relationship with food by having that person’s emotions all mixed up causing them to not care about the things that they cared about before. In some cases having too much stress upon someone causes them to eat more than they used to leading them to gain weight and live an unhealthy life.

Answer:

Nitrogen is essential for plant growth, but farmers who cultivate leguminous plants like pea plants and grams do not apply nitrogen fertilizers during cultivation. This is because leguminous plants have the ability to fix nitrogen from the atmosphere into the soil, making it available for other plants to use. This practice helps the farmers by reducing the need for nitrogen fertilizers, which can be expensive.

Explanation:

Answer:

Nitrogen is an essential macronutrient for plant function and is a key component of amino acids, which form the building blocks of plant proteins and enzymes. Proteins make up the structural materials of all living matters and enzymes facilitate the vast array of biochemical reactions within a plant.

Explanation:

Therefore, the nitrogen deficiency of the soil is fulfilled by the nitrogen fixed by the nitrogen-fixing bacteria present in the root nodules of leguminous plants. Hence, external supply of nitrogenous fertilizers is not required to be added in soil in which leguminous plants are grown.

Weight by volume is a concentration determining the method of the solution. 20 % w/v NaCl is prepared by mixing 3 gm in 15 mL.

Concentration is the amount of the solute or the solvent present in the solution. It can be calculated by molarity, molality, w/v, etc.

( W ÷ 15 ) × 100=20

W = (20 × 15) ÷ 100 =3g

Hence, 3 gm NaCl must be added to 15 mL solution to make it 20% w/v.

( w ÷ 45) × 100=35

w = (35 × 45) ÷ 100

= 15.75 grams

Hence, 15.75 gm NaCl is required to prepare 45 gm solution.

Molarity = number of moles ÷ volume in litres

Given,

Moles = 0.289

Volume = 0.12L

Molarity = 0.289 ÷ 0.12 = 2.4M

Hence, 2.4 M is the molarity of 120 mL of ferric chloride solution.

Number of moles = Molarity × Volume in litres

Given,

Volume = 0.6 L

Molarity = 1.55 M

Substituting values:

Number of moles = 1.55 × 0.6 = 0.93Moles

Hence, 0.93 moles are present in 1.55 M solution.

Given,

Mass = 63 gm

Volume = 0.65 L

Molarity = mass ÷ (molar mass × volume)

M = 63 ÷ ( 58.44 × 0.65)

= 63 ÷ 37.98

= 1.66 M

Hence, 1.66 M is the molarity.

Given,

Molarity = 1.66 M

Volume = 0.5 L

Mass of calcium carbonate = Molarity × molar mass × volume

1.66 × 100.0869 × 0.5 = 83.07 gm

Hence, 83.1 gm is mass required of calcium carbonate to make 1.66 M solution.

Given,

Mass of ferrous chloride = 130 gm

Molar mass of ferrous chloride = 126.751

Molarity = 0.88 M

Volume = mass ÷ (molar mass × molarity)

= 130 ÷ (126.751 × 0.88)

= 1.16 mL

Hence, 1.16 mL solution can be prepared.

M1 = 3 M

M2 = 1.5 M

V2 = 70 mL

V1 is calculated as:

M1V1 = M2V2

V1 = (1.5 × 70) ÷ 3

= 35 mL

Hence, 35 mL of stock solution is required to prepare the 1.5 M solution.

M1 = 6 M

V1 = 3 mL

M2 = 2 M

V2 is calculated as:

M1V1 = M2V2

(6 × 3) ÷ 2 = V2

= 9 ml

Hence, 9 mL is the volume of the desired solution.

Given,

V1 = 17 mL

M2 = 2.4 m

V2 = 65 mL

M1V1 = M2V2

M1 = (2.4 × 65) ÷ 17

= 9.1 M

Hence, 9.1 M is the molarity of the solution that is used to prepare 2.4 M solution.
