Rabbit ears can be either shorter floppy where short ears or dominant over floppy ears there are 653 individuals in a population

of 104 rabbits have floppy years and 549 have short ears find the frequency of dominant and recessive alleles and the frequency of individuals with dominant heterozygous and recessive genotypes

Answer:

frequency of dominant and recessive alleles - 0.6, 0.4

frequency of individuals with dominant,  heterozygous and recessive genotypes - 0.36, 0.48, 0.16

Explanation:

Given -

Short ears (S) is dominant over floppy ears.

Total population of rabbits = 653

Population of rabbits with floppy ears = 104

Population of rabbits with short ears = 549

Frequency of rabbits with floppy ears is equal to

\frac{104}{653} \\= 0.159

Thus as per Hardy weinberg's equation, frequency of recessive phenotype is represented by q^2\\

Thus,

q^2 = 0.159 =0.16\\q = \sqrt{0.16} \\q = 0.4

Thus,

p = 1-q\\p = 1-0.4\\p= 0.6

Frequency of rabbits with short ears only

= p^ 2 \\= 0.6^2\\= 0.36\\

Frequency of heterozygous rabbit (Ss)

p^2 + q^2 + 2pq = 1\\0.16 + 0.36 + 2pq = 1\\2pq = 1 - 0.36-0.16\\2pq = 0.48

Which explanation accurately describes how matter is transformed within the process of photosynthesis?
oksian1 [2.3K]

Answer:

D) The hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. In the Calvin cycle, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.

Explanation:

Photosynthesis is the process by which plants produce carbohydrates (sugars) from carbon dioxide in the atmosphere and water using the energy of sunlight. The process of photosynthesis occurs in two stages: (i) the light-dependent stage and (ii) the light-independent stage.

Light reactions: In this stage, the hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. Also, the energy storage molecule ATP and the reduced electron carrier NADPH are produced.

Light-independent reaction or Calvin cycle: in this stage, carbon atoms from CO₂ are incorporated into ribulose-5-phosphate and used to produce glyceraldehyde-3-phosphate, a three-carbon sugar using the energy of ATP and NADPH from the light reactions. Essentially, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.

What are the overall reactions for photosynthesis and cellular respiration?
dem82 [27]
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water

1) The process arrow A represents is photosynthesis.

2) Arrow A represents light energy transformation. Light energy from the sun is converted into chemical energy in plants.

3) Photosynthesis is part of a carbon recycling process in the carbon cycle. Plants absorb light energy and convert it to chemical energy. Plants absorb carbon dioxide which is exhaled by humans and animals. Plants then produce oxygen which is absorbed by humans and animals. Animals also eat plants thus passing the carbon compounds along.

I hope this makes sense. Hope this helps! :)

Which of the following correctly describes the role of biomolecules in energy storage ?
aleksley [76]

Answer:

Biomolecules are crucial to the storage of energy energy in the body.

Biomolecules conserve energy using covalent chemical bonds.

Explanation

A covalent bond in chemistry refers to a chemical bond that is formed when two atoms share a pair each of electrons.

So some of these molecules which have high energy (such as glycogen and triglycerides) are able to keep or store such energy in the form of covalent chemical bonds. Examples of energy-rich biomolecules are:  

  • glycogen and
  • triglycerides

Cells synthesize such molecules and store them for later release of the energy.            

Cheers
