Shleiden and Theodor Schwann were the first to recognize that all plants and animals are composed of cells.
Hope this helped :)
Answer:
A 50% chance I believe. The mother will always give the X chromosome and since the father is normal and doesn't carry that ressecive trait they can only get it from the mother. (I'm not completely sure!))
Answer:
A- A pH change can cause the enzyme to change its shape
Explanation:
A rise or fall in the pH of the medium from the optimum of pH 7 usually affect the enzymes' active sites of and therefore the shape and the rate of enzyme activity.
Assuming the pH is too low, the enzyme medium becomes acidic;Acidosis. The high Hydrogen ions concentration interacts with the R-groups of the amino acids moiety of the enzymes, this interaction affects the ionization of the R-groups, disrupting the ionic bonding holding these R-groups in shape.
This results in loss of the 3-Dimensional shape arrangements of the protein molecule and therefore of the active sites. Since active sites of enzymes determines the specificity of the <u>enzymes substrate- complex </u> to give <u>enzyme-product complex,</u> the catalytic activity of the enzymes decreases, <u>the rate of reaction decreases,and products formation stops, and the reaction also stops.</u>
The same is applicable to extremely high pH=Alkalosis.
However, the effective buffer system of the body prevents this scenarios from happening in real sense in the body. Through mopping by the haemoglobin, excretion by the kidney, etc
<span>Carbon is the building blocks of all living molecules. With the ability to form carbon-carbon bonds, many different compounds formed into different structures can be used for different purposes such as macromolecules. </span>
Grass I think Bc it’s not a living thing
