Simon is comparing the communities of living things that live in two bodies of water a long river, and the ocean bay just beyond the mouth of the river.
Comparing which of these abiotic factors would be most useful for Simon to explain the differences in the communities? Assume that the water is
unaffected by pollution
A
the salinity of the water
O
B В.
the volume of water in each ecosystem
C. the rate of evaporation of the water
D
the sediments that are deposited on the river bottom or ocean floor
Review progress

Answers

The answer should be A

The abiotic factor that would be most useful for Simon to explain the differences in the communities would be A) the salinity of the water. Salinity refers to the salt concentration in the water, and it can have a significant impact on the types of organisms that can live in the water.

What are abiotic factors?

Abiotic factors are the non-living components of an ecosystem, including physical and chemical factors such as temperature, sunlight, water, soil composition, air, and nutrients. These factors can significantly affect the living organisms and communities within an ecosystem.

The ocean bay is likely to have a higher salinity than the river because of its connection to the open ocean. Therefore, the types of organisms that live in the ocean bay may be better adapted to higher salinity levels, while the river may support a different community of organisms that are adapted to lower salinity levels.

The other factors listed (volume of water, rate of evaporation, and sediments) may also impact the communities of living things in the two bodies of water, but salinity is likely to be the most significant factor.

When glycogen is formed from monosaccharides, it occurs by a process called hydrolysis.

True

False

Answers

Answer:

yes its true. it occurs by a process called hydrolysis

The formation of glycogen from monosaccharides happens through the process of dehydration. So the statement is false.

What is the process of glycogen formation?

The process of formation of glycogen is called glycogenesis. Glycogen is the storage form of glucose, a primary carbohydrate in the liver and the muscle cells of animals

The process of Glycogenesis happens when the levels of glucose in the blood are high enough to allow the excess glucose to be stored.

The process of glycogenesis is stimulated by the insulin hormone. It helps the muscle cells to uptake glucose into themselves. Insulin is not required for the transport of glucose into the liver cells.

However, insulin has very important effects on the metabolism of glucose inside the liver cells. Insulates stimulates the process of glycogenesis and inhibit the process of glycogenolysis, which is the breakdown of glycogen into glucose.

Therefore the statement is false.

a essay explaining why i choose a certain university​

Answers

Answer:

Because the facilities here for my subject are second to none” – this shows that your subject has been at the forefront of your mind when making a sensible choice of university, again demonstrating your level of commitment to it. You can mention specific facilities to show that you’ve read into it thoroughly.

“Because I liked the approach this university takes to my course” – even within the same subject, every university takes a slightly different approach to the way it’s taught and structured. The university question is another good opportunity to show that you’ve really thought about the course and gone to the effort of finding a university whose approach to the subject you agree with. You can even name specific modules that set this university’s course apart from the others offering the same subject.

Along similar lines, you could also mention the university’s great reputation for your subject, or the presence of certain lecturers you feel inspired by (though don’t let this last point dominate your answer; lecturers often move about or go on sabbatical, so even if there’s a particular academic you admire, they may not end up teaching you).

Intermediate disturbance

Linear regression is used to examine the relationship between nitrogen concentration and plant growth. The correct option is A.

What is linear regression?

When modelling the relationship between a scalar answer and one or more explanatory variables in statistics, linear regression is a linear method.

Simple linear regression is used when there is only one explanatory variable, and multiple linear regression is used when there are numerous variables.

The processes that underlie the experimentally based nitrogen productivity hypothesis can be investigated using model equations.

It depicts a linear relationship between relative growth rate and plant nitrogen concentration and has a negative intercept at a nitrogen concentration of zero, is consistent with this theory.

Thus, the correct option is A.
