These include clumped, even, and random. If individuals are evenly dispersed, they are located at equal intervals. If they are clumped, they are bunched together in clusters. Random dispersion means the location of each individual is determined by chance. The most common type of dispersion in nature is clumped.
D) This is a point mutation, resulting from the substitution of one nitrogen base. If this strand of DNA is used for transcription, it will affect the coding of ONE amino acid, resulting in placing the correct amino acid in the protein, placing the wrong amino acid in the protein, or coding for the protein to stop building.
Answer:
The answer to the question: Class II MHC proteins are found on which of the following cell types, would be: on macrophages and lymphocytes, particularly T-Cells.
Explanation:
MHC, or Major histocompatibility complex, is a very important part of the immune response that the body gives against an invading pathogen, or other foreign substances. There are three types in the human body, Class I, Class II and Class III and each of them will play a role on the cellular membrance of different types of cells and mediate different types of responses. In the human body, this histocompatibility complex is best known as HLA, or human leukocyte antigen, and it will ensure the recognition, or non-recognition of substances, tissues, and other organisms, by the human immune system. Class II, as mentioned before, are most usually found on the immune cells macrophages and lymphocytes, and they are the ones responsible for presenting antigens to these proteinic antibodies so that the immune cells can initiate a proper immune response.
B because it takes in nutrients through endocytosis so the membrane opens up and envelopes the nutrients
Answer:
He can deduce that The pO2 of her cells is less than or equal to 200 mmHg.
Explanation:
Partial pressure of oxygen(pO2) measures the amount of gaseous oxygen dissolved in the blood. It purposes to measure the effectiveness of the lungs in pulling oxygen from the atmosphere to the lungs.
In the incubator where the gases levels are carefully regulated, a pO2 of 200mmHg on the incubator deduces that the pO2 of her cells is equal or less than 200mmHg.
