D is the most logical answer

Answer from: hipstergirl225

D. Shelly and Jason inherited different combinations of 23 chromosomes from their mother and 23 chromosomes from their father.

Explanation:

All people receive exactly the same number of chromosomes from their father and hand. This is because, all people have the same number of chromosomes, which are divided in the formation of gametes. Leaving specifically, everyone has 46 chromosomes, during a crossing gametes are formed, the male gamete has 23 chromosomes, and the female gamete has 23 chromosomes.

In this way we can say that Shelly and Jason received the same number of chromosomes from their father's and their mother's. However, as Mendel discovered in his experiments, the father and mother alleles are inherited by the children completely independently, which means that Shelly and Jason inherited different combinations of 23 chromosomes from the mother and 23 chromosomes from the father.

Answer from: Quest

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

The diagram below represents a marine food web and a process that can harm the human population. each circle represents an organism and the smaller dots inside them represent a toxic substance. what is being represented and how does it harm the population? the diagram represents biological half-life, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents the process by which different organisms prey upon each other; this can impact the human population by reducing the number of organisms that do not contain the toxin. the diagram represents the way that toxins are metabolized by living organisms, with those at greater trophic levels able to metabolize more efficiently than those at lower levels. this means that those at higher tropic levels are safer for humans to consume compared to the organisms at lower trophic levels.
