Answer 1

The lytic and the lysogenic cycles are the two methods that bacteriophages reproduce.  They both begin with a bacterium that has been infected with bacteriophage DNA.

Lytic:

The phage DNA reinstructs ribosomes and the bacterium begins producing many bacteriophages.The bacterium eventually lyses and releases the bacteriophages into the environment

Lysogenic:

The phage DNA is incorporated into the bacterium's chromosome.The bacterium eventually duplicates this DNA when it undergoes fission, producing two infected daughter cells.Eventually, the phage DNA will be read by the bacterium and it will go into the lytic cycle, described above.

To sum it up, the lytic cycle ends the bacterium's life by producing offspring, yet the lysogenic cycle allows for multiple bacteria to divide and eventually undergo the lytic cycle.

If convection cells in the asthenosphere are the mechanism behind plate tectonic movement, what powers the convection cells?

a) energy from the sun
b) energy from the earth's core
c) air pressure changes
d) energy from magma

Answers

I think the answer will be C

The energy that powers the convection cells is ENERGY from the earth's core (Option B).

Convection currents, also known as convection cells, are caused by density differences within a body of liquid or gas.

Convection cells inside of the Earth form as material near the Earth's core heats up.

The asthenosphere refers to the upper mantle layer beneath the lithospheric mantle which is involved in plate tectonic movement.

The heat inside the Earth's core heats the asthenosphere, which is associated with the movement or 'motion' of convection cells.

In conclusion, the energy that powers the convection cells is ENERGY from the earth's core (Option B is correct).

Metalloids that can conduct electricity at high temperatures are called semiconductors.



Semiconductors are a group of elements that have properties intermediate between those of metals and nonmetals. They have some characteristics of metals, such as being able to conduct electricity, but also some characteristics of nonmetals, such as having lower conductivity than metals.

At low temperatures, semiconductors have very low conductivity. However, at high temperatures, they can conduct electricity more effectively. This is because at higher temperatures, the thermal energy causes more electrons to break free from their atoms and become available for conduction.

One example of a semiconductor that can conduct electricity at high temperatures is silicon. Silicon is widely used in electronic devices, such as computer chips and solar cells, due to its ability to control and amplify electrical signals.

In summary, metalloids that can conduct electricity at high temperatures are known as semiconductors. They have properties intermediate between metals and nonmetals and can conduct electricity more effectively at high temperatures. Silicon is an example of a semiconductor commonly used in electronic devices.

Which of the following is NOT a source of nitrogen that is available to plants?

Answers

Answer:

I CANT SEE THE FOLLOWING BUT I WILL EXPLAIN.

Explanation:

Plants usually absorb nitrogen from NO3- and NH4+

Nitrogen oxides released into the atmosphere by burning fossil fuels and organic matter is not a source of nitrogen which is available to plants. Thus, the correct option is D.

How does plants take nitrogen?

Plants require nitrogen as it is a macronutrient. The deficiency of this nutrient can cause many diseases. However, plants cannot themselves obtain the nitrogen from air but they rely mainly on the supply of combined nitrogen atom in the form of ammonia molecule, or nitrate molecule, resulting from the nitrogen fixation through free-living bacteria in the soil or the bacteria living symbiotically in the nodules on roots of legumes.

Plants can take nitrogen through absorbing the soil by their roots. Plants cannot get this nitrogen directly from the air. Although, the nitrogen element is abundantly available in air. Nitrogen is unreactive atom, and it cannot be used by the green plants to make proteins. Nitrogen gas needs to be converted into nitrate compounds in the soil through nitrogen-fixing bacteria in soil, root nodules or lightning. Every nitrogen atom is triple-bonded to another nitrogen atom to form the molecular nitrogen, N₂.

Therefore, the correct option is D.

Which of the following terms are used to indicate that cell membranes will allow only certain molecules to pass through without assistance?
A. Selective Permeability
B. Open Bilayer
C. Homeostatic Membrane
D. Temporary Permeability

Answers

The answer is c Homeostatic Membrane

The plasma membrane separates the cell from the outer environment. It only allows the movement of certain molecules through selective permeability. Thus, option A is correct.

What is selective permeability?

Selective permeability is the property that allows the movement and transportation of the molecules inside the cell through active or passive transportation.

It is seen in the plasma or the cell membrane of the cell as it allows only certain specific molecules to enter or leave the cell. It is important for the protection of the cell.

This allows the exchange of the nutrients and waste produced in and out of the cell. The selective permeability is the semi-permeability that is due to the lipid bilayer of the membrane.

Therefore, option A. the cell membranes are selectively permeable.

Answers

i think its c. magnesium Mg

The element needed by the chemist to perform the experiment with similar properties to that of potassium, while having lower atomic mass is option B. Sodium.

If we take a look at the periodic table, we can see all the elements that share properties with potassium are located within the same column. Some examples are :

SodiumRubidiumCesium Lithium

Of the elements listed, only two are found within the options for this question, which means that we can discard option C and D.

We can then proceed to analyze the atomic mass of each element in an attempt to choose the option with a lower atomic mass than Potassium. Option A, Rubidium, has an atomic mass that is much higher than the 39 of potassium, which means we can discard option A. The correct choice is option B, Sodium , since it shares similar properties and has an atomic mass of 22.

One day eve was walking by the tree when a serpant asked her why they didn't eat from it. She replied by saying that God asked them to not eat from that tree. The serpant told Eve that God just doesn't want them to be knowledgeable like him. She took a bite of the apple and then gave some to Adam. They then realized that they were naked and made clothing from animal skin. This was what created sin. They tried to hide from God but he already knew and he banished them from the garden with angels and a fire sword at the enterance. He went to the serpant and cursed him for telling Eve to eat from the tree. Adam and Eve went on their way and had 2 boys. Cane and Abel.

Is mass conserved in chemical reactions?

Answers

Answer:

Mass is not conserved in chemical reactions. ... This means that the total mass and energy before a reaction in a closed system equals the total mass and energy after the reaction. According to Einstein's famous equation, E = mc2, mass can be transformed into energy and energy can be transformed into mass.

Explanation:

Answer:

Mass is not conserved in chemical reactions. The fundamental conservation law of the universe is the conservation of mass-energy. This means that the total mass and energy before a reaction in a closed system equals the total mass and energy after the reaction. According to Einstein's famous equation, E = mc2, mass can be transformed into energy and energy can be transformed into mass. This is not some exotic process, but in fact happens every time there is a reaction. Mass is therefore never conserved because a little of it turns into energy (or a little energy turns into mass) in every reaction.

Explain the process of DNA isolation.

Answers

Answer:

Lysis, precipitation and purification

Explanation:

DNA isolation is a molecular biology technique based on the extraction of DNA and subsequent purification to remove inhibitors that may hamper the process of amplification. DNA isolation consists of three steps:

1- Lysis: it consists of the mechanical disruption of the cell, where the nucleus is broken to release DNA. During this process, it is required to use enzymes and detergents such as Proteinase K

2- Precipitation: during this process, the DNA is precipitated by using alcohol and salt.  

3- Purification: this process removes the impurities from DNA. Extraction is carried out by washing DNA with ethanol and water.
