D. are made in the bone marrow.

Answers

Answer 1

Answer:

Answer;

A. can live for many years.

Unlike red blood cells, white blood cells can live for many years.

Explanation;

-Blood has four main components: plasma, red blood cells, white blood cells, and platelets.

-Red blood cells live for only about 120 days. As they wear out and age, they are captured and disposed of by cells in the spleen and other organs.

-White blood cells are different from red blood cells in several important ways. Unlike red cells, white cells are complete cells. They are larger than red cells and have a nucleus. White blood cells are not just carried by the blood stream, they can also move about independently. Additionally, Unlike red blood cells, white blood cells can live for many years.

Answer 2

Answer: The answer is neither of the above. All the above features except A relate to the red blood cells. (A is not true for both red blood cells and white blood cells.)Red blood cells or RBCs carry oxygen, are the most numerous cells (36 - 50%) in the blood and they are made in the bone marrow. The life span of RBCs is 120 days or 4 months.On the other hand, white blood cells or WBCs produce antibodies to develop immunity against infections and some are phagocytic against pathogens. They make up about 1% of the blood and are produced in the thymus. The lifespan of WBCs is 4 - 30 days.

Answers

Based on the diagram, letter A corresponds to the Golgi Body or Golgi Apparatus. This organelle is found in most eukaryotic cells, including the animal cells. The Golgi Body, or simply Golgi, was named after the Italian scientist Camillo Golgi for his discovery of this cell component in 1897.

Answer: there are six possible genotypes

Explanation:

With three alleles 1, 2, 3

genotypes: 11, 12, 13, 22, 23, 33. First we must appreciate that genes do not act in isolation. The genome in which a genotype is found can affect the expression of that genotype, and the environment can affect the phenotype.

Answers

It seems that you have missed the given options for this question, but anyway, the correct answer is the term LINKAGE. When two loci are on the same chromosome, progeny sometimes do not exhibit the phenotypes that would be predicted by the law of independent assortment and this outcome can be explained by the phenomenon of linkage.

Peter Rodman proposed that human evolution was linked to ________ while Owen Lovejoy suggested the best explanation was ________. a. the ability to carry food in order to provision family members; increased efficiency in walking as forests transformed to wooded environments b. the increased efficiency in walking as forests transformed to wooded environments; the ability to carry food in order to provision family members c. the ability to make and use stone tools; the loss of the diastema and evolution of thick enamel d. the early emergence of a large brain; the later emergence of a large brain

Answers

Answer:

b. increased efficiency in walking as forests transformed to wooded environments; the ability to carry food in order to provision family members.

Explanation:

Peter Rodman and his colleague proposed a 'patchy forest hypothesis' according to which forests become more patchy and the food in them is in dispersed form so, the hominids their can move efficiently with energy and can carry food now with free hands.

While Owen Lovejoy suggested that monogamous males, provision their females and protect them from predators, females that are provided with foods, could now take care of more than one offspring at a time, and thus reduce the gap between births.

Final answer:

Rodman proposed that human evolution was driven by efficiencies in walking due to environmental changes while Lovejoy suggested it was due to the ability to carry food and provision for family members.

Explanation:

Peter Rodman and Owen Lovejoy were anthropologists who each contributed significant theories about the forces that drove human evolution. According to their theories, Peter Rodman proposed that human evolution was linked to the increased efficiency in walking as forests transformed into wooded environments. This transformation would have required our ancestors to travel further for resources, thus selecting for those who could walk more efficiently. On the other hand, Owen Lovejoy suggested the best explanation was the ability to carry food in order to provide for family members. In his view, the capacity to carry food would have promoted pair bonding and increased survival of offspring, propelling human evolution.
