Suppose that ear length in rabbits is controlled by two additive genes, each of which has two alleles. A true-breeding female (a

abb) with 6-cm ears is mated to a true-breeding male (AABB) with 16-cm ears. Predict the ear length of the F1 generation. (Note: Assume that each allele contributes equally to ear length, and the genes segregate independently. Also assume that environmental influence on ear length is negligible.)

Answer:

The ear length will be 11 cm.

Explanation:

To know about the ear length of F1 generation, we need to know that how much length in centimeters is contributed by each of the alleles. As we know, each allele has the same value for contributing to the effect of ear length, hence we can divide the ear length by 4 to get our results.

As 6 divided by 4 is 1.5 hence, the allele a and b contribute to 1.5 cm of the length of the ear.

6 divided by 4 is 4, hence the alleles And B contribute to 4 cm of the length of the ear.

The F1 generation will have AaBb genotype hence, the lenght will be 4+1.5+4+1.5 = 11 cm.

Which could be a pathway of food through an ecosystem?​
algol13

Answer:

Sun > Grass > Deer > Lion

Explanation:

The sun begins a food chain because its light is needed for a plant, in this case grass, to grow.

An animal that eats grass is the deer, who is a primary consumer.

An animal that eats deer is the lion, who is a tertiary consumer in this case.

The lion has no natural predator, and thus is at the top of this food chain.

This ecosystem can be one found where grass, deer and lions exist, for example, the deciduous forest in the eastern United States.

A set of genes whose transcription is regulated by an operator gene is called a(n) _______.
shepuryov [24]
The answer is operon. These set of genes are transcribed together because they share a single promoter and operator. Therefore they are transcribed into one mRNA and translated together. These genes are, therefore, expressed together at all times. Examples are the tryptophan and lac operons of Escherichia coli

photosynthesis and cellular respiration both use electron transport chains. what is the source of electrons for photosynthesis a
goldfiish [28.3K]

Water serves as an electron source in the electron transport process of photosynthesis. The electron is extracted from water by using solar energy.

What is the electron transport chain's source of energy?

The electron transport chain uses the energy released by oxygen and reduced compound reactions such as cytochrome c and (indirectly) NADH and FADH2 to pump protons into the intermembranous space, producing the electrochemical gradient over the inner mitochondrial membrane.

In photosynthesis, water is split to produce electrons in the presence of sunlight, a process known as the photolysis of water. The electrons are finally transferred to NADP+ by the chloroplast electron transport chain, where they are reduced to NADPH.

Therefore, In aerobic respiration, electrons from NADH and FADH2 are transferred to oxygen by the mitochondrial electron transport chain to reduce oxygen in the water.
