Answer:

Protein synthesis

Explanation:

Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation.

Answer:

The correct sequence is:III) Antigenic determinants from pathogen bind to antigen receptors on lymphocytes.

IV) Lymphocytes specific to antigenic determinants from pathogen become numerous.

II) Lymphocytes secrete antibodies.

I) Pathogen is destroyed.

V) Only memory cells remain.

Explanation:

Effective resistance against infection is essential for the development and functioning of the mammalian organism, and for it to be effective, multiple defense systems must be available. In order to meet these objectives, the body has developed a complex system of overlapping and interrelated defense mechanisms, which together can destroy or control almost all invaders.III) Antigenic determinants from pathogen bind to antigen receptors on lymphocytes. It consists of the binding of the foreign antigen to the specific receptors existing on the membrane of mature lymphocytes. The B lymphocytes that mediate humoral immunity express antibody molecules on their surface, which bind to foreign proteins, polysaccharides or lipids in their soluble form; T lymphocytes, responsible for cellular immunity, express so-called T cell receptors (TCR), which recognize small sequences of antigenic peptides.

IV) Lymphocytes specific to antigenic determinants from pathogen become numerous.II) Lymphocytes secrete antibodies.

Activation phase: sequence of events that occur in lymphocytes as a result of specific antigen recognition. All lymphocytes undergo two fundamental changes: a) proliferation: expansion of antigen-specific clones and amplification of the protective response, in which the CD4 T lymphocyte, capable of activating CD8 B and T lymphocytes, assumes a preponderant role; b) differentiation: stage in which effector cells and memory cells are formed. The first produce various substances that can interact with the antigen, such as antibodies and lymphokines; the second are partially differentiated lymphocytes, that is, they do not become effector cells.

I) Pathogen is destroyed.

In this phase, the T lymphocytes differentiated into effector cells migrate to the sites of attack, where they carry out their functions of eliminating pathogens, while the B lymphocytes perform them in the peripheral organs themselves.

V) Only memory cells remain.

One of the most important consequences of the adaptive immune response is the establishment of the state of immunological memory, which lies in the ability of the immune system to respond more quickly and efficiently to microorganisms that have previously infected the host and it reflects the preexistence of a clonally expanded population of antigen-specific lymphocytes. We call, therefore, the immune response that the organism gives when it comes into contact for the first time with a foreign agent and from which a series of events derives that include nonspecific innate defense mechanisms and adaptive response mechanisms, if the pathogen manages to survive the first ones.

Answer:

Implantation is the mechanism by which a blastocyst, which is passing through the uterus as a developing embryo, makes contact with the uterine wall and remains bound to it before birth. The uterine lining (endometrium) undergoes several internal modifications in order to allow for the emerging blastocyst to bind to it.

Explanation:

- Eijiro <3

Answer: yes

Explanation:

Answer:

B

Explanation:

Answer:

True

Explanation:

The first contact that an organism has with a particular antigen will result in the production of effector T and B cells which are activated cells that defend against the pathogen. ... Memory T and memory B cells are also produced in the case that the same pathogen enters the organism again.

The answer is 4-8.

Answer:

50% will have ears

Explanation:

To have ears you must have the trait nn since the ears trait is recessive,  2 of the four possible offspring are like this, so 50%

Answer: Aquifers that are drying up are mainly near arid climates, large cities, or agricultural stations, like farms.if the aquifer is shallow enough and permeable enough to allow water to move through it at a rapid-enough rate, then people can drill wells into it and withdraw water Excessive pumping can lower the water table so much that the wells no longer supply water they can "go dry."

Answer: Root growth begins with seed germination. ... The zone of elongation is where the newly formed cells increase in length, thereby lengthening the root. Beginning at the first root hair is the zone of cell maturation where the root cells begin to differentiate into special cell types.

This would be the The integumentary system

Explanation:

I will write it in comments

Answer:

See explanation

Explanation:

A precipitate is formed when a mixture of two soluble substances results in the formation of an insoluble product. It usually happens during a double decomposition reaction.

The two clear liquids combined both contain soluble substances. These interact to yield an insoluble product also known as a precipitate which is black in colour and settles on the bottom of the beaker.

Answer:

i believe it is 27.3

Answer:  

Trackways/footprints, mold and cast fossils, feeding marks, coprolites, and burrows. Trace fossils show the activity of ancient organisms rather than the body fossil itself. However, it is rather difficult to identify an organism by use of mere trace fossil, and therefore, it is less accurate.

Hi there!

I think the answer would be a protist that is a heterotroph and has chlorophyll. The protist falling under this category is called Euglena. Euglena has the ability to synthesize food using its chlorophyll, but if the light gets scarce it can utilize its heterotroph qualities and catch food instead.

Answer:

A would be the best answer.

Explanation:

A seems to be the answer that matches data shown on the graph.

Cyanide binds to Fe3+ in heme-containing proteins. This inhibits the terminal cytochrome complex IV of the electron transport chain. The blocklock of complex IV by cyanide depletes ATP culminating in cell death. Oxygen is unable to reoxidize the reduced cytochrome a3. Thus, cellular respiration is inhibited, as well as ATP production, in essence depriving the cells, tissue, and, ultimately, the whole body of oxygen. Hypoxia evolves into metabolic acidosis and decreased oxygen saturation. The extent of lactic acidosis indicates the severity of the cyanide poisoning. In a collapsed individual, plasma lactate is an indicator of cyanide poisoning. In severe cyanide poisonings, up to 98% of the cyanide in the bloodstream is tightly bound to red blood cells. The ancillary response is myocardial depression and decline in cardiac output. Bradycardia, hypotension, and cardiac arrhythmia then develop into VF and cardiovascular collapse.
