The answer is B.

Water in the form of vapor enter the atmosphere. The vapor accumulates in the atmosphere to form clouds. Once the clouds are heavy enough, the water in the form of droplets fall towards land or as rain. It could also be in the form of other precipitation such as snow or hail. As the sun hits the waters in the land, it causes the water to evaporate and the cycle continues.

If the diameter of the afferent arterioles leading to the glomerulus increases (vasodilation) net filtration pressure will incre
Vinvika [58]

True. If the diameter of the afferent arterioles leading to the glomerulus increases due to vasodilation, which ultimately increases the net filtration pressure.

The filtration of blood occurs in the kidney, an excretory organ. The kidney is composed of numerous small units called nephrons, which is responsible for the blood filtration.

Glomerulus is part of nephron and the glomerular filtration occurs in the renal corpuscle of the kidney. This process is driven by hydrostatic and colloid osmotic pressure.

These pressures are collectively called net filtration pressure, which is influenced by the diameter of afferent arterioles.

If the arterioles constricts, net filtration pressure will decrease and if arterioles dilates, net filtration pressure will increase. This mechanism is regulated by neural, renal and hormonal regulation.

What would be the effect of a mutation in the coding region of the lactase gene?
Fynjy0 [20]

Lactase refers to an enzyme that can dissociate lactose sugar into glucose and galactose. This enzyme plays an important role in the digestion of milk that comprises high lactose sugar. In case, if a mutation occurs in the gene codon of lactase, then two possibilities can take place. These are as follows:  

1. Loss of mutation: In this case, the person becomes lactose intolerant because of mutation in lactase gene codon. Due to this, there is low mRNA expression and thus low production of the enzyme lactase. This is also known as lactase non-persistent phenotype.  

2. Gain in mutation: In this case, the person gain an increase in mRNA expression of the lactase gene, thus more production of lactase takes place than usual. This kind of individual exhibits lactase persistent phenotype.

Parland’s alligator population has been declining in recent years, primarily because of hunting. Alligators prey heavily on a sp
IRISSAK [1]

Answer:

(C) The main predator of these fish is another species of fish on which alligators also prey.

Explanation:

The ecosystems are complex systems, and removing one species of them, always has a chain reaction and affects the population of the other species, be it in a positive or negative manner. In this case, the alligators prey upon fish, multiple different species. The alligators though have been removed from the ecosystem, thus the apex predator exists no more. This has opened up the top predator niche in the food chain in this particular ecosystem. The predatory fish species had no predators of its own, so its population increased, thus it needed more food, and that food was obtained by hunting the other fish species, resulting in a decline in the population of the other species of fish. Only when the carrying capacity is reached in the ecosystem for the predatory fish, the population of the other fish will stop declining.

Answer:

1. in animal cell and 3. in plant cell In animals mitochondria transforms energy and chloroplast in plant cell  absorb energy from sun light and turns water and carbon dioxide into glucose

Explanation:

1. Mitochondria: It is the powerhouses of a cell oval in shape found in eukaryotic cell.Its a site of cellular respiration. It converts glucose in chemical energy known as ATP (Adenosine triphosphate). ATP provides energy to carry out cellular function by breaking high energy bond.Mitochondria are abundant in cells requires energy to perform functions such as muscle and liver cells.

2. Chloroplast: In plants and algae chloroplast is a site of photosynthesis,it contains a pigment chlorophyll which captures energy from sunlight and turn water and carbon dioxide into glucose as food of plants.
