A genetics researcher finds that a form of human albinism in a certain population is controlled by the recessive allele, a, for the absence of skin pigment and the completely dominant allele, A, for presence of skin pigment. If the recessive allele occurs in 30% of this population, what percent of the population has skin pigment but also carries the recessive allele?
21 percent
42 percent
91 percent
51 percent

Answers

Answer 1

You must use the concept of the Hardy-Weinberg equilibrium,thus the option b 42percent is the right answer.

Define equilibrium?

Equilibrium is defined as a state of balance among both opposing forces or deeds that can be static (such as when forces are applied to a body and the resultant is zero) as well as dynamic (such as during a reversible chemical reaction. when the speeds in both directions are equal). This state can be either mental or emotional.

Is balance a part of equilibrium?

The forces are equalised if an entity is in equilibrium. The main word used to characterise equilibrium conditions is balanced.

define dorsiventral leaf

Answers

A dorsiventral (Lat. dorsum, "the back", venter, "the belly") organ is one that, like an ordinary leaf, has two surfaces that differ in appearance and structure from each other. As a synonym for dorsoventral organs, those reaching from the dorsal to the ventral surface, this term has also been used.

A dorsiventral leaf, also known as a bifacial leaf, is a type of leaf structure characterized by having distinct upper and lower surfaces with different functions and structures.

The upper surface of a dorsiventral leaf is called the adaxial surface, while the lower surface is called the abaxial surface. The adaxial surface is usually dark green and is exposed to more sunlight, while the abaxial surface is typically lighter in color.

This structural asymmetry allows for efficient photosynthesis on the upper surface while minimizing water loss through stomata on the lower surface.

Dorsiventral leaves are commonly found in dicotyledonous plants and contribute to their overall shape and function in terms of light absorption, gas exchange, and transpiration.

Explanation:

Ducks are aquatic birds. Their feet are webbed and this trait makes them fast swimmers. Biologists believe that ducks evolved from land birds, which did not have webbed feet. How could this have happened

Answers

Answer:

Random chance mutations led to the webbed feet trait in ancestral land birds, conferring them an adaptive advantage. Birds that inherited the beneficial random mutations associated with the webbed feet trait had more chances to survive and reproduce, passing this trait to the next generations.

Explanation:

Mutations are ramdom changes in the nucleotide sequence of the genome of a particular organism. In general, mutations are deleterious, but mutations may occasionally be beneficial in certain environments. A beneficial mutation must be associated with one or more phenotypic traits capable of conferring an adaptive advantage in a certain environment, thereby the individuals carrying the mutation have more chances to reproduce and survive. In this case, one or more beneficial mutations associated with the webbed feet trait passed to the next generations, increasing their frequency in the population.

~They process information going into the neuron
~They eliminate foreign substances inside neurons.
~They provide insulation for axons.

Answers

Answer:

~They process information going into the neuron

Explanation:

This is because Glia or neuroglia cells are cells found in the central nervous system that is brain and spinal cord and they did not transmit electrical impulses. Glia cells don't carry information because they don't carry electrical impulses. The cells include epipdymal cells,Schwann cells e.t.c.

Pollinization is the transference of pollen grains to the stigma. Fertilization occurs when pollen grains move to the ovary and gametes meet. Option D. 2,3,4,1

What is pollinization?

Pollinization is the pollen transference from the masculine organs to the feminine organs of the flower. It might involve the same flower or different flowers, the same plant or different plants.

What are the Feminine reproductive structures?

The central structure is known as a carpel, also recognized as the pistil.The base of the carpel forms the ovary, in which the eggs are produced and where the zygote develops.The opposite extreme of the carpel is the stigma, in the superior part. The stigma is a sticky surface where the pollen grains get attached.The style is the filament structure that connects the ovary and the stigma.

What are the Masculine reproductive structures?

The pollen grains, or male séx cells, are produced in the stamens.

The stamen has an anther where the pollen is produced, and a filament that provides support.

What is fertilization?

Fertilization is the gamete fusion, which involves the mature germinated pollen grain and the ovule.  

During fertilization

1) The mature pollen grains are driven to the stigma of the same flower or other flowers of the species, where they stick.

2) Once in the stigma, the pollen grain germinates.

3) A thin structure named pollinic tube forms. It goes from the stigma along the style and ends in the flower ovary.

4) The pollen grains move along the tube forward to the ovary, where they meet the egg and fertilize.

5) Once in the ovary, the pollen grains get in touch with the ovule. They have double fertilization.

6) The zygote develops in the ovary.
