Darwin referred to the process of promoting certain traits by breeding members with those traits as _______.

Answers

Answer 1

Artificial selection

Answer 2

Darwin referred to the process of promoting certain traits by breeding members with those traits as Artificial selection.

What is Artificial selection?

Artificial selection is the process of identifying desirable qualities in plants and animals and then taking action to strengthen and pass those traits on to succeeding generations.

Artificial selection operates in a similar manner to natural selection, with the exception that in natural selection, these judgments are made by nature without human intervention.

In laying out the evidence for his theory of evolution by natural selection in his 1859 book, On the Origin of Species, the British naturalist and biologist Charles Darwin highlighted the physical traits and behaviors of several species of bird called finches.

Therefore, Darwin referred to the process of promoting certain traits by breeding members with those traits as Artificial selection.

Glycoproteins on the cell membrane would prevent someone with type a blood from accepting type b blood.
a. True
b. False

Answers

I believe the statement is true. Glycoproteins on the cell membrane would prevent someone with type A blood from accepting type B blood. Glycoproteins are type of proteins that has an oligosaccharide chain or glycol that is covalently bonded to a polypeptide side-chain. This molecule is involved in almost all of the processes in a cell. It functions in the reproductive system, immune system, protection of the body and communication of the cells. It is also important for the red blood cells. Our blood types are named according to the type of glycoprotein that is present in our red blood cells. With this, it helps the body identify that your blood cells are yours and are not foreign cells.

A client who just returned from a cardiac catheterization reports to the nurse that the pressure bandage on the right groin is tight. what action should the nurse take?

The nurse should assess the pulses that are distal to the dressing. This is necessary in order to assess the regularity, strength and rate of the pulses. A strong pulse reflects a good perfusion status. If the pulse is weak, that means that circulation is been hindered.

Answers

The inhibition of enzymes can occur in three ways: competitive, noncompetitive and substrate inhibition. The enzyme here is the amylase. The substrate could be the chemical and the nutrients that could be broken down from the plants. In this case, the chemical is a competitive inhibitor, since it 'overtakes' the nutrients in the active site of the enzyme. Then, the enzyme could not do its job of digesting the plant.

Human blood type AB is an example of which pattern of inheritance?

incomplete dominance

dominant/recessive

heterozygous

codominance

Answers

The correct answer would be Dominant/Recessive.

Blood type AB exemplifies codominance, where both IA and IB alleles are equally expressed. The ABO system is also a case of multiple alleles inheritance, with three alleles involved. This differs from incomplete dominance, which is not exhibited in blood type AB.

Human blood type AB is an example of codominance. In the ABO blood group system, alleles IA (encoding antigen A) and IB (encoding antigen B) are both expressed equally in the phenotype of the heterozygote, resulting in blood type AB which displays both A and B antigens on the surface of red blood cells. This is different from incomplete dominance, where the phenotype is a blend between the two alleles. Additionally, the ABO blood types are an example of a multiple alleles inheritance pattern since there are three alleles involved (IA, IB, and i), which increases the possible blood types.

The ABO blood group antigens are an example of the complexity of genetic inheritance, showing both codominance and a multiple allele system, but not incomplete dominance. It is important to understand these concepts in genetics to grasp how different traits are passed from parents to offspring.

Drug-resistant populations of microbes arise when

Answers

There is variation within the population, due to a mutation. The selection pressure is the drug. The microbes that have the advantageous gene which makes them resistant to the drug are selected for, and reproduce passing on the gene, increasing its allele frequency within the population over time. However, the microbes that do not have the advantageous gene, cannot survive and their number decreases within the popullation.

Final answer:

Drug-resistant microbes arise from the survival and reproduction of microbes that have developed resistance to antibiotics, often due to an incomplete course of treatment. They then create new populations of resistant microbes.

Explanation:

Drug-resistant populations of microbes arise when those microbes are exposed to antibiotics but are not completely killed off. This can happen when a course of antibiotics is not fully completed, allowing some bacteria to survive and develop resistance. When those resistant bacteria reproduce, the resulting offspring also carry the resistance, leading to a whole population of bacteria that cannot be killed by that specific drug. This is why it is essential to always complete a full course of antibiotics.

A patient undergoing chemotherapy for lymphoma (cancer) was advised to get rid of the house plants in her home. what is the possible reasoning behind this suggestion?

Answers

Chemotherapy patients are advised against gardening, planting or any form of contact with soil. The soil in the pots is a huge source of bacteria and mold, which presents an unnecessary danger to the patient. Removing indoor houseplants and flowers are also advised because these items tend to shed mold in the air and can be a source of infection. It is also important to not keep cut flowers inside the house because the water in the vases can harbor infectious bacteria and can evaporate in the air and spread to the patient.

Chemistry is the study of the properties of matter and how matter changes. This study includes the concepts of chemical changes, which refers to the transformation of one kind of matter into another, and chemical properties, which describe the behavior of matter in relation to changes it undergoes when it transforms.

Explanation:

The study of the properties of matter and how matter changes is referred to as Chemistry. Chemistry is a physical science that deals with the structure, composition, properties, and reactions of matter. Furthermore, it also encompasses the concepts of chemical changes and chemical properties. A chemical change refers to a process that changes one kind of matter into another kind, producing a different kind of matter from the original. Chemical properties, on the other hand, describe the behavior of matter related to changes it undergoes when it transforms to another kind of matter.

When an olfactory receptor is stimulated, a generator potential must be produced by the receptor before it signals the brain that a change has occurred.
