Why is it important to maintain the ph of blood and tissue fluids within normal limits?
Sladkaya [172]

It is important to maintain the ph of blood and tissue fluids within normal limits because the structure and function of macromolecules are pH sensitive, and even little variations from normal pH can cause metabolic processes to shut down.

Tissue fluid is found in the spaces around cells. It comes from substances that leak out of blood capillaries (the smallest type of blood vessel). It helps bring oxygen and nutrients to cells and to remove waste products from them.

The two forms of connective tissue in this subcategory are blood and lymph. Both are fluid rather than solid, and neither has the network of extracellular protein fibers that other types of connective tissue have.

Diffusion and filtration processes create tissue fluid from plasma. This fluid fills the intracellular space and serves as a link in the transmission of nourishment, gases, and metabolic end products between blood capillaries, tissue fluid, and lymph.

A true-breeding plant that produces yellow seeds is crossed with a true-breeding plant that produces green seeds. The F1 plants
nadya68 [22]

Answer:

The phenotypic ratio will be 3:1

Explanation:

As per this question there are two phenotypes for seed color, yellow and green. Both the parents are true breeding that means they are homozygous for this trait. Also, all the F1 plants have yellow seed color which clearly indicates that yellow seed color is a dominant trait while green is recessive trait.

The cross of true breeding plants as mentioned above is depicted as under:

Parents                             YY    x   yy

                                          /   \       /   \

F1 generation                Yy   Yy  Yy   Yy

So, as per the law of dominance because of the presence of Y allele, all these progeny will be yellow in color.

Next, when these F1 plants will be crossed, the result will be as under:

F1 generation                    Yy   x    Yy

                                         /   \         /   \

F2 generation               YY   Yy   Yy   yy

The genotypic ratio of F2 generation is 1:2:1

The phenotypic ratio of F2 generation is 3:1

It simply means that in F2 generation, 3 progeny which have allelic combination YY & Yy will be yellow colored while 1 progeny which has allelic combination yy will have green color.

all of the following are forms of energy a living organism can use except: heat mechanical chemical nuclear
yuradex [85]

All of the following are forms of energy a living organism can use except nuclear energy. Nuclear energy is the use of nuclear reactions that release nuclear energy to generate heat ( thermal energy is being transferred between two objects).Exposure to any radioactive material and energy  is bad because the nuclear energy damages human body and cells.
