Answer:

<u><em>The answer is</em></u>: <u>100%.</u>

Explanation:

According to Mendel's laws, and taking into account that bulls and roan cows have red and white hairs together.

We will use "F" for the animal hair color allele.

F R = allele for red hairs

F W = allele for white hairs

red x white -------> red and white animals

F R F R x F W F W ----> 100% F R F W

<u><em>The answer is</em></u>: <u>100%.</u>

pychu [463]
<h2>Endothermic Process</h2>

Explanation:

An example of endothermic process is :

Heat is needed for water to boil.

Endothermic process can be defined as a process in which heat energy is absorbed from the surrounding that bring about changes in the molecular level like breaking chemical bonds, inter-molecular force of attraction etc.

Boiling of water is an endothermic process because during this process water absorbs heat , its kinetic energy increases and then it boils.

Svet_ta [14]

Answer:

The human population is yet to reach its carrying capacity. However, the following will suggest that humans have reached their carrying capacity.

1. When humans are unable to increase food production which is expected to sustain a larger population.

2. When humans' use of resources, in general, is greater than resource availability.

Explanation:

The human population is yet to reach its carrying capacity. However, the following will suggest that humans have reached their carrying capacity.

1. When humans are unable to increase food production which is expected to sustain a larger population.

PLEASE HELP ITS URGENT What is the functionof the peripheral nervous system? A. To transmit signals between the body and the bra
Rzqust [24]

Answer:

The peripheral nervous system (PNS) is one of the two components of the nervous system, the other part is the central nervous system (CNS). The PNS consists of the nerves and ganglia outside the brain and spinal cord.[1] The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body.[2] Unlike the CNS, the PNS is not protected by the vertebral column and skull, or by the blood–brain barrier, which leaves it exposed to toxins and mechanical injuries. The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. In the somatic nervous system, the cranial nerves are part of the PNS with the exception of the optic nerve(cranial nerve II), along with the retina. The second cranial nerve is not a true peripheral nerve but a tract of the diencephalon.[3]Cranial nerve ganglia originated in the CNS. However, the remaining ten cranial nerve axons extend beyond the brain and are therefore considered part of the PNS.[4] The autonomic nervous system is an involuntary control of smooth muscle and glands. The connection between CNS and organs allows the system to be in two different functional states: sympathetic and parasympathetic

What is not a feature of rbc morphology?
kotegsom [21]

The given question is incomplete as options are not provided, however the options are as follows:

A. a large surface area-to-volume ratio

B. ability to form stacks known as rouleaux

C. a convex shape allowing for more efficient transport of oxygen

D. ability to bend and flex when entering capillaries

Answer:

The correct answer is - option C.

Explanation:

RBC cells are biconcave in the shape it is form shape of dub bell in general. These cells are small, round. The biconcave shape of the blood cells helps in the flow of the blood easily and these cells have no nucleus like other cells to have high amount of hemoglobin that is a pigment that carry oxygen and other gases for easy gaseous exchange.

Due to their flexible biconcave shape they can bend and flex accordingly during entering capillaries. The shape of the RBC helps in making stacks and large surface to area ratio.

Thus, the correct answer is - option C.

Why human with heterozygous genotype will have the dominant phenotype?
AnnZ [28]

A human with heterozygous genotype can have a dominant phenotype if one of the alleles complete mask the effects of the other.

  • Heterozygous genotype involves two different alleles, unlike homzygous genotypes in which the alleles are the same.
  • When the two alleles of an heterozygous genotype exert equal effects on one another, they are said to be codominant.
  • When one of the alleles of an heterozygous genotype incompletely exert its effects on the other allele, it is said to be incomplete dominance.
  • When one of the alleles complete dominates and masks the effects of the other allele, it is said to be dominant.

Hence, a dominant allele will always produce a dominant phenotype even if the genotype of the organism is heterozygous.
