Elena L [17]3 years ago
3 0

Answer:

D

Explanation:

A is incorrect because leukocyte is a colorless cell that circulates in the blood and body fluids and is involved in counteracting foreign substances and disease; a white (blood) cell.

B is incorrect because phagocytes are a type of cell within the body capable of engulfing and absorbing bacteria and other small cells and particles.

C is incorrect because lymphocyte are a form of small leukocyte (white blood cell) with a single round nucleus, occurring especially in the lymphatic system.

D is correct because erythrocyte are a red blood cell that (in humans) is typically a biconcave disc without a nucleus. Erythrocytes contain the pigment hemoglobin, which imparts the red color to blood, and transport oxygen and carbon dioxide to and from the tissues.

The diagram represents some stages in the 19. development of the modern horse, according to evolutionary theory. The diagram is
alexdok [17]

Hello. You forgot to add the diagram.

The diagram is attached below.

Answer:

1. examination of homologous fossilized structures of primitive horses

Explanation:

As you can see in the diagram, to show the stages of the development of the modern horse, a comparison is made between the forelimb structure and the molar tooth of these horses (related to the adult form). These two factors of comparison establish the representation of fossilized homologous structures of primitive horses.

As you may already know, homologous structures are different body structures from different animals that have a strong similarity (because they are inherited from a common ancestor). When these animals die and these structures are conserved, we can say that they have been fossilized.

As the forelimb structure and the molar tooth of the horses shown in the diagram are homologous structures that were fossilized, we can say that option 1 is the correct answer to your question.

What type of immunity exists when a person is exposed to an antigen and subsequently makes antibodies against the antigen?
Anni [7]

Acquired immunity is the type of immunity that exists when a person is exposed to an antigen and subsequently makes antibodies against the antigen.

Immunity is the defense mechanism of the nervous system to avoid pathogens affecting the body and making it sick. There are two major types of immunity: innate and acquired. Innate immunity is the kind of immunity present in the human body by birth. Whereas, acquired immunity is gained over time.

Acquired immunity specifically promotes the antibodies or lymphocytes to inhibit the action of pathogens when it encounters one. It is further categorized into two types: active and passive immunity.

Active immunity indulges in the primary response to a pathogen. It produces antibodies to fight against it and preserves some to fight against the same pathogen encountered for the second time. Passive immunity, in addition, involves the medications prescribed to enhance immunity.

To know more about acquired immunity, refer to the following link:
