Answer:
b. the activity of lipoprotein lipase.
Explanation:
Lipoprotein lipase (LPL) is considered or known to be a rate-limiting enzyme that hydrolyzes circulating triglyceride-rich lipoprotein such as very low density lipoproteins and chylomicrons.
It is known that the Lipoprotein lipase is activated by glucagon and adrenaline. And this why the activity of LPL increases in muscle tissue and decreases in adipose tissue, during fasting while , its activity decreases in muscles tissue and increases in adipose tissue.
It is known that, it plays an important role in breaking down fat in the form of triglycerides, which are carried from various organs to the blood by molecules called lipoproteins.
In conclusion, women fat cells in the breasts, hips, and thighs produce abundant LPL, storing fat in those body sites , while in men, fat cells in the abdomen produce abundant LPL.

Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Before anaphase begins, the replicated chromosomes, called sister chromatids, are aligned at along the equator of the cell on the equatorial plane. The sister chromatids are pairs of identical copies of DNA joined at a point called the centromere.

During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle. The mitotic spindle is made of many long proteins called microtubules, which are attached to a chromosome at one end and to the pole of a cell at the other end. The sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell.

Anaphase ensures that each daughter cell receives an identical set of chromosomes, and it is followed by the fifth and final phase of mitosis, known as telophase.

Answer: The best way for farmers to prevent fungi from growing is to make sure there is not enough moisture for fungi to survive and grow
Explanation: Fungi require moisture or water for a wide number of reasons. One of the best guesses I can give as a reason to why they might need it is to help them in the process of digestion. Fungi use digestive enzymes which are specially shaped proteins that break down macromolecules like glucose or cellulose and a number of other biological molecules, and they do this through one of two processes, dehydration synthesis, or hydrolysis. Hydrolysis in particular is the one that requires water. It uses pieces of water to break a bond between complex sugars and carbohydrates among other molecules, to separate them into smaller and easier to absorb monomers which are the subunits that make up the molecule. It breaks apart the water and uses the pieces to fill in the gaps of the pieces the monomers used to share.
Answer:
A rock's exposure to the weathering elements and its surface area can affect its rate of weathering. Rocks that are constantly bombarded by running water, wind, and other erosion agents, will weather more quickly. Rocks that have a large surface area exposed to these agents will also weather more quickly.
Explanation:
Properties of the Parent Rock ;
- The mineralogy and structure of a rock affects it’s susceptibility to weathering.
- Different minerals weather at different rates. Mafic silicates like olivine and pyroxene tend to weather much faster than felsic minerals like quartz and feldspar. Different minerals show different degrees of solubility in water in that some minerals dissolve much more readily than others. Water dissolves calcite more readily than it does feldspar, so calcite is considered to be more soluble than feldspar.
-
A rock’s structure also affects its susceptibility to weathering. Massive rocks like granite generally to not contain planes of weakness whereas layered sedimentary rocks have bedding planes that can be easily pulled apart and infiltrated by water. Weathering therefore occurs more slowly in granite than in layered sedimentary rocks.
