Answer:

It may be that synthesis in population dynamics has been slow to emerge because population change is more complicated than it first appears. After all, population change is determined ultimately by only four factors: birth, death, immigration, and emigration.

Explanation:

Research has shown that population size and growth are important factors in the emission of greenhouse gases. ... While population-driven emissions from developed nations are estimated to contribute 42 percent of CO2 emissions between 1985 and 2020, they are expected to contribute only 3 percent between 2025 and 2100.

If sewage is only partially treated before it is disposed of, it can contaminate water and harm huge amounts of wildlife. Alternatively, leaking or flooding can cause completely untreated sewage to enter rivers and other water sources, causing them to become polluted. The consequences aren't great

+Social and cultural factors. ...

+Availability of family planning. ...

+Female labour market participation. ...

Answer:

D) Beta galactosidase will not be produced.

Explanation:

Promoter is necessary to start the transcription of the structural gene. The position of promoter is important because the gene which is downstream to promoter will be transcribed and the gene upstream to the promoter will not be transcribed.

Lac operon has three structural gene lacZ, lacY, and lacA. Lac Z codes for β galactosidase, lac Z codes for permease and Lac A codes for transacetylase. So if promoter for the lac operon moves between the beta-galactosidase (lacz) gene and the permease (lacy) gene, then the beta-galactosidase gene will not be produced because it is places upstreamed to the promoter.

Marine biologists have determined that when a shark detects the presence of blood in the water, it will swim in the direction in

blondinia [14]

Blood concentration is approximated by the distance from the source.

The concentration of blood at a point P(x,y,z) on the surface of sea water is approximated by the distance from the source where the blood moves. Point x is the place where the concentration of the blood is the highest because at this point the source of blood present.

At point y, the concentration of the blood is lower as compared to point x but higher than point z, while on the other hand, at point z the concentration of blood is the lowest due to its presence farther from the source so we can conclude that blood concentration is approximated by the distance from the source.

Glucagon secretion is stimulated when blood glucose concentration decreases. which carbohydrate pathways does glucagon stimulate

Ugo [173]

The correct answers are gluconeogenesis and glycogenolysis.

Glucose is the prime energy source, which is utilized by the body. Glucagon refers to the peptide hormone, which enhances the levels of glucose in the body when its amount is critically low in the blood.

The upsurge in the number of glucose levels in the bloodstream is encouraged by the processes, gluconeogenesis, and glycogenolysis. Gluconeogenesis refers to the metabolic pathway, which generates glucose molecules, this generally occurs in the liver.

Glycogenolysis refers to the biochemical dissociation of glycogen molecules to glucose. It takes place in the liver tissues.

Which statement is true of succession? Most communities are already completely stable. Most communities take hundreds of years t

Setler79 [48]

Answer:

Option B, Most communities never become completely stable

Explanation:

In an ecological succession, most of the species are unstable and they keep on changing continuously. The succession is primarily of two types –

a) Primary Succession – In this, community of species occur on a new habitat which had been never occupied earlier. Or it can be said that it is entirely a new habitat.

b) Secondary Succession – In this, community of species occur in a habitat where earlier life existed but it was disturbed or damaged by some environmental condition.

Hence , the correct answer is option B
