Answer:
Median height is selected
Explanation:
Stabilizing selection is a particular type of natural selection where the mean of the trait in the population stabilizes on non-extreme phenotypes, thereby favoring intermediate phenotypic variants. At genetic level, stabilizing selection is shaped by selective forces that push the distribution of the trait in the population toward the average (median trait), it is a condition that may happen when a population is completely adapted to its environment. Thus, stabilizing selection acts to purge the extreme phenotypic variants via purifying selection. Stabilizing selection is considered to be one of the most important mechanisms controlling the distribution of different phenotypes after many cycles of artificial selection, it s for that reason that breeders believe that this type of natural selection is the most common in nature.
Answer:
An antigen presenting cell present antigens to helper t lymphocyte is called Macrophage.
Explanation:
Macrophage belong to the family of antigen presenting cell. Macrophage along with the help of low molecular weight protein cytokines migrates to the site of inflammation. After reaching that site Macrophage engulf the antigen and destroy the later by the process called cell eating or phagocytosis.
Then the antigenic fragements are presented to Helper T cell with the help of a protein molecule known as Major Histacompatability complex or MHC.
Answer:Hopefully you feel comfortable with what a number line is. A graph is two number lines (called the x axis and the y axis) which cross each other at zero. A linear equation is a relationship between the two number lines. So if I gave you the linear equation “y=x”, this means if you pick a number on the x axis, the equation tells you what the number is on the y axis. So if you picked x=10, then you would know y=10. You can then draw a point at the co-ordinate (10,10), the point is there to tell you that the equation is true at that point. You can then pick another x, say x=9, then you know y=9 and you can put a point at (9,9), so you know the equation is true at that point also. You can do this with any number that you pick for x, and if you did that for every number, all the points you draw would turn into a line.
Explanation:
True. It takes in O2 and released Co2
Answer:
Biochemistry is the branch of science that explores the chemical processes within and related to living organisms. ... Biochemistry focuses on processes happening at a molecular level. It focuses on what's happening inside our cells, studying components like proteins, lipids and organelles.
