Two rough black guinea pigs when bred together have two offspring. One of them is rough white and the other is smooth black. What are the genotypes of these parents?

Parent 1 __________ Parent 2 ___________

Answers

Answer 1

Answer:

Parent 1 = RrBb

Parent 2 = RrBb

Explanation:

This question involves two genes in guinea pigs. The allele for rough coat (R) is dominant to smooth coat (r), and the allele for black coat (B) is dominant to white coat (b).

According to this question, two rough black guinea pigs when bred together produced two offsprings. One of the offsprings is rough white (R_bb) and the other is smooth black (rrB_). This means that, to produce such offsprings, the parents must be both heterozygous for both genes (RrBb). Please find the punnet square for this cross attached

Can a gene mutation that does not influence phenotype be considered an adaptation? Why or why not?

Answers

Answer:

No; only a small percentage of mutations cause genetic disorders—most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene.

Answers

Answer:

parenchyma have primary cell walls (thin) and are unspecialized and metabolically active (photosynthesis, respiration)

collenchyma have primary cell walls (unevenly thick) which provide a level of structural support in areas of high growth, they are alive so have a protoplast

sclerenchyma have secondary cell walls which means they have lignin and are thick, they are functionally dead at maturity so provide support in areas that are done growing and are involved in transport of water

Explanation:

Given is a strand of DNA, fill in the corresponding RNA strand and find which amino acids that strand codes for.

Answers

Answer:

The correct answer would be -

RNA - AUG GGG CCU UAC UAA

Amino acid -methionine-glycine-proline-tyrosine -stop codon

Explanation:

In the process of protein synthesis, the first process is known as transcription which involves the transcribing the mRNA strand from the DNA strand in a complementary manner. In this manner, Adenine transcribes into uracil and cytosine transcribe into guanine similarly thymine into adenine and guanine into cytosine.

Then, DNA strand - T-A-C-C-C-C-G-G-A-A-T-G-A-T-T will change into AUG GGG CCU UAC UAA and every three codes represent a triplet codon that translates into an amino acid first code called start codon and normally code for methionine (AUG) and last code for stop and does not code any amino acid.

Then, the amino acid will be - methionine-glycine-proline-tyrosine -stop codon

Answers

Answer:

In order to find out the rate of respiration.

Explanation:

The soda lime in the respirometer absorbs carbon dioxide gas  which is important in this investigation because we measure the rate of respiration and for measuring that we have to measure the rate of oxygen and carbondioxide so that's why soda lime absorb carbondioxide gas in the respirometer. Growth and movement are the two uses of energy in a fly larva. The energy that is produced in the fly larva is used for the growth of the body and other activities such as mobility etc.

What are your top 3 favorite lifeforms and why? What adaptations help these living things to survive in their environment?

please help

I will give brainliest for the best answer

Answers

Answer:

so it's saying what are your favorite animals or plants or living things and how do they survive

hi!! here's ur answer!!

my top 3 favourite lifeforms are- polar bears,tigers and ducks. :D

1) polar bears- are well adapted for survival in the Arctic. Their adaptations include: a white appearance - as camouflage from prey on the snow and ice. thick layers of fat and fur - for insulation against the cold.

2) tigers- striped coat helps them blend in well with the sunlight filtering through the treetops to the jungle floor. The tiger's seamless camouflage to their surroundings is enhanced because the striping also helps break up their body shape, making them difficult to detect for unsuspecting prey.

3) ducks- possess an oily coating that keeps water from settling in their feathers, helping them in staying dry and keeping themselves warm. Their webbed feet, designed like paddles, provide more surface area to push against the water and help them swim.

hope it helps:)

B) smooth muscle only
C) smooth muscle and cardiac muscle only
D) smooth muscle, cardiac muscle, and some skeletal muscle

Answers

Answer:

answer part d

Explanation:

smooth muscle, cardiac muscle, and some skeletal muscle

Involuntary muscle includes smooth muscle and cardiac muscle only.

What is meant by involuntary muscle?

Muscles that contract or move voluntarily are known as involuntary muscles. Involuntary muscle action is controlled by the autonomic nervous system. The internal organs or viscera that exhibit consistent, gradual contractions and involuntary motions are typically connected with these muscles. The heart is one such uncontrollable muscle.The autonomic nervous system, hormones, and local variables can cause the involuntary activity of the majority of involuntary muscles by neural stimulation. But in other muscles, such as the walls of visceral organs, extending the muscle can cause an involuntary muscle contraction.

Therefore, option (C) is correct.
