Answer:
Crossing over
Explanation:
Crossing over is the process during which two chromatids of two homologous chromosomes exchange part of their genetic segments. It occurs during the pachytene stage of prophase I of meiosis I.
Linked genes are mostly inherited together and do not exhibit independent assortment. However, when linked genes are present far apart from each other on the same chromosome, crossing over can occur between them to produce recombinant chromatids. Therefore, crossing over can break the linkage and produce recombinant progeny as it occurs during the independent assortment of unlinked genes.
Answer:
The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, vitamins green spinach, Fat and oil or lipids from sunflower seeds, proteins...
The Carbohydrates is processed into glucose, proteins is processed into amino acids, lipids is processed into fatty acids and glycerol.
Explanation:
From the food consumed, The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, green spinach contains vitamins like vitamin K, vitamin A, vitamin C, vitamin B12 , minerals like magnesium, iron, Fat and oil or lipids from sunflower seeds, proteins...
The Carbohydrates is processed into glucose after enzymes like salivary amylase acts on it from the chewing and in the stomach which produces glucose which makes it easily absorbable , proteins is processed into amino acids by the activity of hydrochloric acids and protease that processed it into amino acids, lipids is processed into fatty acids and glycerol by the activities of the enzymes lipase.
The minerals and vitamins present are in a way they can be absorbed.
Answer: D.) It allows water to resist freezing and thawing cycles.
The ability of the water molecule to absorb and retain heat is called as heat capacity of water, because of this property the temperature of water remains the same for long, irrespective of the external environment. It allows water to resist freezing and thawing cycles because water molecules will resist change in it's temperature. This temperature regulation will prevent instant heating and cooling, hence, will provide suitable environment for the survival of marine organisms.
The best answer is C.
Enzymes are proteins that speed up the process of chemically breaking down food molecules. In other words they act as catalysyts. Catalaysts increase the rate at which chemical reactions occur without being consumed or permanently changed themselves.
A chemical reaction is a process that converts one or more substances known as substrates to another type of substance which is termed the product. As a catalyst, an enzyme can repeat the same type of reaction over and over again. Each enzyme has an active site where its specific substrate binds so that a reaction can begin to take place and continue to completion.
