Answer:
The options are:
A. Did a lack of Rain cause the hemlocks to stop reproducing?
B. Are deer eating most of the young hemlocks?
C. Do the young hemlocks have a disease?
D. Why are there so many deer in the forest?
The answer is B. Are deer eating most of the young hemlocks?
Hemlocks are referred to as plants which are considered poisonous when eaten by animals. Since Deers are herbivorous and eats plants alone then the most suitable option will be B which talks about if the deers are eating most of the young hemlocks as a result of it being closely related to the relates to the fosters observation and the collective scientific data on forest.
Answer:
B. Masturbation.
Explanation:
Mutual masturbation occurs when two people masturbate together with consent.
Coitus is sexual intercourse, so two people are needed and doesn't count as masturbation per se.
Fellatio is oral stimulation of one's penis.
Cunnilingis is oral stimulation of a female's vagina.
Hope this helps :)
Answer:Plant cells have plasmodesmata, a cell wall, a large central vacuole, chloroplasts, and plastids. Animal cells have lysosomes and centrosomes.
Explanation:The best answer
The type of nervous tissue that contain neuronal cell bodies, dendrites, unmyelinated axon, axon terminals and neuroglial cells is the GRAY MATTER OF THE BRAIN. The gray matter of the brain include regions responsible for muscle control, sensory perception, memory, emotion and self control. The gray matter processes information in the brain.
Complete question:
1. In Model 1 a pathogen (virus, bacteria, foreign protein, parasite) has entered the bloodstream of an individual. Describe the symbol that represents the pathogen.
3. Another type of white blood cell that is involved in the cell-mediated response is a helper T-cell.
a. Draw the symbol that represents the helper T-cell in Model 1.
b. In your drawing above, circle the specialized surface proteins on the helper T-cell.
Answer:
1. The pathogen is the one with the "star-like" symbol
3. a) The helper T-cell is represented like a Circle with the Th wrote inside.
b) The surface protein on the Th cell is the symbol that looks like this ⊥
or T Th cells.
<em>Note: All the symbols are shown in the attached file</em><em>.</em>
Explanation:
- Pathogens: These are invading the bloodstream, so you can see them among the white cells, and too many of them.
- Macrophages are one of the different types of white globules involved in the organism's defense against strange substances and pathogen agents. These cells are the principal actors in the immune response.
- Macrophages are the principal phagocytes of tissues, capable of recognizing different strange molecules that penetrate the organism, such as bacterias, parasites, and viruses. Macrophages phagocyte these substances and eliminate them, a process known as phagocytosis. Macrophages also have the capability of inducing an adaptative immune response. Macrophages show the antigens on their surfaces where they are recognized by lymphocytes.
- Helper T-cell: T-Lymphocytes are in charge of the regulation of the immune system. T-cells are the helper cells that coordinate the initial response in front of the pathogen. There are three types of helper T-cells: TH1 (lymphocyte T helper), TH2, and TH17. TH1 cells are highly effective during the elimination of intracellular pathogens.
