Which scenario causes gene flow

Answers

Answer: Migration is one way that genes are transferred from one population to another.

Explanation:  Gene flow is caused by a significant change in the population of individuals due to the addition of other individuals whose alleles are slightly different from those of the existing individuals

Answer:

Introgression refers to gene flow from another taxon. While low levels of gene flow between species are not uncommon, it is a serious issue when an introduced invasive species hybridizes with a native species and overwhelms its genetic constitution (genetic swamping). This is a major threat in canids, ducks, fish and plants. For example, exotic rainbow trout introduced into the habitats of native cutthroat trout in the Western United States led to hybrid swarms that eventually overwhelmed the local species. Introgression is readily detected by molecular genetic and genomic methods.

some of the advantages of inorganic farming.

Answers

Answer:

With the use of pesticides, farming can be faster and it also detracts insects and weeds

Answer:

One advantage inorganic fertilizers offer is that they are fast acting. These nutrient-rich salts dissolve quickly and are immediately available to the plants depending on them to provide essential nourishment in the form of nitrogen, phosphorus and potassium.Organic fertilizers usually contain plant nutrients in low concentrations. Since many chemical/inorganic fertilizers are concentrated and very soluble, it's easier to apply too much and damage your plants. Fresh, non-composted manure can damage your plants as well, because some manure contains harmful amounts of salts

Where are metamorphic rocks likely to form?

Answers

Answer:

You would most likely find metamorphic rocks if you dug deep into the earth. This is because these types of rocks form in areas of extremely high heat and pressure.

Answer: deep in planets crust

Explanation:

Although metamorphic rocks typically form deep in the planet’s crust, they are often exposed on the surface of the Earth. This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment.

Answers

I couldn't see ur picture But I think from the options I think the answer is option D

D) organisms are made up of large number of cells

The feature of cell theory that is best demonstrated in the image is organisms are made up of a large number of cells. Thus, the correct option for this question is D.

What is Cell theory?

The cell theory was proposed by two famous scientists. i.e. M.J. Schleiden and T. Schwann. There are three assumptions that fall under the cell theory.

All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.It is the basic structural and functional unit of life.

Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells.

According to the three assumptions given above, the one which is best demonstrated by the image is that Organisms are made up of a large number of cells.

Therefore, the correct option for this question is D.

Which type: Land breeze or sea breeze would most likely form on a warm, cloudless, summer day? How do you know? Explain

THXSSS PLEASE HELP AND HURRY

Answers

Answer:

Explanation:

Sea breeze is a breeze that comes from the ocean to the land. The breeze is usually more when the temperature difference between land and ocean is high especially when it is summer and hot afternoon.

When the temperature is hot both land and water are been heat up, the land begin to release heat and warm air will rise over the land. Water do not get heat up easily hence the air is cooler leading to high pressure on the ocean air then blows from here to the land.

Answer:

Sea breeze.

This is because sea breeze occur on hot summer days which is due to unequal heating on the land surface and sea surface

Explanation:

Land and Sea breezes are as a result of different rate of heating on land or sea surfaces along coastal areas.

Sea breeze occur in a warm, cloudless summer days because of the unequal heating of the land and water surfaces.

During the day, the land surface heat more that the water surface. The air that is above the land become warm and it is warmer than that on the sea surface but the warm air is lighter than cool air. The warm air above the land surface rise, and the cool air on the sea surface rises and replaced the land warm air . This is sea breeze
