Answer:

J

Explanation

A nucleotide consists of a sugar molecule (in this case, deoxyribose), a phosphate group and a nitrogenous group. Based on this definition of a nucleotide, J would be the most appropriate answer as it lists deoxyribose (sugar molecule), a phosphate group and the nitrogenous base cytosine.

Answer:

The correct answer is - с. These organelles are both important for the conversion of energy to a usable form for cells.

Explanation:

Chloroplast and mitochondria are the two organelles that are essential for the biosphere specially autotrophs like plants and heterotrophs as chloroplast is the organelle that converts light energy into chemical energy by forming sugars by the process called photosynthesis by trapping the sunlight.

This chemical energy that is stored in glucose molecule moves to the mitochondria where by the procee of the cellular respiration the chemical energy converted to the ATP, the energy form that is used by the cell for the performing its function.

The first two structures that combine during the process of translation are 1 and 4.

The translation is a biological process during which the genetic codes in transcribed DNA, in the form of messenger RNA, are translated to their respective amino acids and joined together by peptide bonds to form proteins.

The steps involved in the translation process are:

In the image, mRNA is designated as 4 while tRNA is designated by 2. 1 is the ribosome while 3 is the synthesized protein.

Thus, the first two structure that binds is mRNA and tRNA. That will be 1 and 4.

See the answer below

Explanation:

The inheritance of flower color in the plant species follows the simple dominance/recessive inheritance of Mendel. The red flower trait did not show up at all at F1 only for it to show up at F2. It simply means that the red flower trait is recessive while the violet flower color is dominant.

Assuming that the allele for violet flower color is designated as R while that of red flower color is designated as r.  The genotype of the violet flower would be true-breeding, RR, while that of red flower color would also be true-breeding rr:

                RR    x    rr

 F1         Rr    Rr    Rr    Rr  

phenotype ratio = all violet flower color

                 Rr    x    Rr

F2          RR    Rr    Rr    rr

phenotype ratio = 3/4 violet flower color and 1/4 red flower color

97 red flower offspring out of 400 is approximately 1/4.

Hence, the inheritance of flower color in the plant obeys a simple dominant/recessive Mendelian law with the violet color trait dominant over the red color trait.

Answer:

In crabs, gills are more inferior to lungs in O2 uptake, but they are both quite efficient.

Explanation:

Hope this helped!

Answer:

Both are used for oxygen intake and excretion

Explanation:

In all species, the lungs were extremely effective in oxygen uptake whilst the performance of the gills was inferior. An exception to this was Gecarcoidea natalis, which has gills highly modified for aerial gas exchange; its gills and lungs were equally efficient in O2 uptake. The relative efficiencies of the lungs and gills in CO2 excretion differed between species, with the gills being the major site of CO2 loss in the more amphibious species and the lungs having an increasingly important role in the more terrestrial crabs. The presence or absence of lung portal systems was not found to correlate with either saturation rates or efferent oxygen concentrations, with both lung types being extremely efficient in O2 uptake. The lungs with portal systems showed a large increase in oxygen content in the first lacunar bed and progressively smaller increases in the next two; these lungs may, therefore, have some reserve for exercise.

Answer:

75%

Explanation:

The allele for purple flowers (capital P) is dominant.

The allele for white flowers (lowercase p) is recessive.

If one allele is capital P, it doesn’t matter if the other allele is another capital P or a lower case p, the capital P will dominate and purple flowers will show up.

The Punnett Square shows:

PP, Pp, Pp, and pp

• 3 of the offspring have at least one dominant and capital P, so purple flowers show up.

• 1 of the offspring has two lowercase and recessive alleles (p), so white flowers show up.

3/4 or 75% of the offspring will have purple flowers.

[tex]\huge\boxed{Option A}[/tex]

Pea plant has purple color flowers dominant over white color flowers.

Purple flower dominant allele is P

White Flower recessive allele is p

We would get White flower pea plant only when the recessive allele is in HOMO.ZYGOUS condition

_________________________________________________________

Hom.ozygous Dominant Alleles: PP (Purple Flower)

Heter.ozygous Dominant Alleles: Pp Purple Flower)

Hom.ozygous Recessive Alleles: pp (White Flower)

Whenever we cross Heterozygous Dominant(Pp) purple flower with another Heterozygous dominant (Pp purple flower), we get 75% of the flowers PHENOTIPICALLY(physical appearance) white flowered, and 25 white flowered Because as you can see in the picture,

The P1 is Pp

The P2 is Pp

When we cross them,

It has 4 offsprings,

PP Hom.ozygous Purple flower  

Pp Heterozygous Purple flower

Pp Heterozygous Purple flower

pp Hom.ozygous white flower

Thus the answer is 75% as there are phynotypically 3 purple flowers present

Explanation:

According to Newton's first law of motion, the answer would be true.

The Newton's first law of motion states that a body will either continue to rest or in motion unless an external force acts on it.

The body represents a mass. Hence, that a mass in motion would remains in motion unless acted upon by some force represents a version of Newton's first law of motion.

Answer:

A

Explanation:

Answer:True

Explanation:

Answer:

Low temperatures slow down chemical reactions, the action of enzymes, and delay or inhibit the growth and activity of microorganisms. The lower the temperature, the slower the chemical reactions, enzymatic action and bacterial growth will be.

Explanation:

Refrigeration consists of keeping the products at low temperatures, but above their freezing temperature. Refrigeration prevents the growth of microorganisms that can withstand temperatures above 45º C and many that can survive temperatures ranging from 15 to 45º C. If we lower the storage temperature of perishable foods, we will be able to significantly reduce the speed of reproduction of the vast majority of microorganisms, which cause decomposition and generate possible diseases in consumers. Refrigeration decelerates the metabolism of organic matter until it stops almost completely when we reach -18 ° C (international conservation standard for most frozen products), in addition to achieving partial or total inhibition of altering processes in food, such as certain enzymatic reactions or the metabolic degradation of proteins, thus delaying the decomposition of these.

Proteins

Answer:

The correct answer is a) 48.16 grams of HCl will be produced, b) mass of chlorine consumed is 206 grams.

Explanation:

a) The reaction given is:

K₂S₂O₃ + 4Cl₂ + 5H₂O ⇒ 2KHSO₄ + 8HCl

Based on the given information, the mass of KHSO4 is 45 grams. The moles of KHSO4 can be determined by using the formula,  

Moles = given mass/Molar mass

= 45/136.16

= 0.33 Moles of KHSO₄

From the reaction it can be seen that when 2 moles of KHSO₄ is produced, 8 moles of HCl is also produced. Therefore,  

2 moles of KHSO₄ = 8 moles of HCl

So, moles of HCl will be,  

Moles of HCl = 8 × 0.33/2

= 1.321 moles

Now the mass of HCl is,  

Mass of HCl = Moles of HCl × Molar mass of HCl

= 1.321 × 36.46

= 48.16 grams of HCl

b) It is known that 1 mole is equal to 6.023 × 10²³ molecules

In the given case, the molecules of water is given, that is, 2.20 * 10²⁴ molecules. Now let us consider that the moles of water is x.  

x mole of water = 2.20 × 10²⁴ /6.022 × 10²³

= 3.653 mole of H2O

From the reaction given, it can be seen that when 5 moles of water are consumed, 4 moles of chlorine are consumed.  

5 moles of water = 4 moles of chlorine

3.653 moles H₂O = x moles of Cl₂

Moles of Cl₂ = 4 × 3.653 /5  

= 2.906 moles Cl₂

Now the mass of Cl₂ determined as,  

Mass of Cl₂ = moles of Cl₂ × Molar mass of Cl₂

= 2.906 × 70.9

= 206 grams

Answer:

D. The oxygen atom is negatively charged and the hydrogen atoms are positively charged.

Explanation:

A water molecule is consists of two hydrogen bonds and one oxygen bond. The hydrogen and oxygen atoms share unequal electrons to form covalent bonds.

Due to unequal sharing of electrons oxygen atoms attracts electrons more strongly than the hydrogen atoms and oxygen gains a slightly negative charge and hydrogen atom gains slightly positive charge.

Hence, the correct option is "D. The oxygen atom is negatively charged and the hydrogen atoms are positively charged."
