Answer:

Gene flow within a population can increase the genetic variation of the population, whereas gene flow between genetically distant populations can reduce the genetic difference between the populations.

Explanation:

Gene flow within the population increases the genetic variability in the wolf population variation can be seen.

Gene migration is another name for gene movement. The movement of genetic material from one group to another is referred to as gene flow.

Through migration, gene flow can occur between two populations of the same species and is mediated via vertical gene transmission from parent to offspring and reproduction.

Any movement of people and the genetic material they carry from one community to another is referred to as gene flow, often known as migration.

Therefore the movement of genetic material from one population to another is known as gene flow.

Answer: earthquake

Explanation: earthquakes shake and have these techtonic plates. this causes the ground to break.

Answer:

two homologous chromosomes travel together into one new daughter cell.

Explanation:

in metaphase I the tetrads line themselves up at the metaphase plate and homologous pairs orient themselves randomly. in anaphase I centromeres break down and homologous chromosomes separate. in telophase I chromosomes move to opposite pols; during cytokinesis the cell separates into haploid cells.

Insulin helps control blood glucose levels by signaling the liver + muscle fat cells to take glucose from the blood. It then helps the cells to take the glucose to be use for energy, and if the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.

Asbestos can cause cancerous mesothelioma in the lungs.

Overexposure to UV rays in sunlight can cause skin cancer.

Smoking can cause lung cancer and chewing tobacco can cause oral cancer.

The DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells is nucleus.

The part of a cell that houses the chromosomes in biology. The membrane-enclosed nucleus is where RNA is synthesised from the chromosomal DNA.

DNA is organised into chromosomes in the nucleus, which is located in the centre of the cell.

The double nuclear membrane (outer and inner) that separates the nucleus from the cytoplasm, known as the nuclear envelope, envelops it. The rough endoplasmic reticulum and the outer membrane are one unit.

The nucleolus' main job is to facilitate ribosome biogenesis by assembling and digesting rRNA into preribosomal particles.

Bacterial cells lack the nucleus, the primary cell structure that houses DNA, that is present in plant and animal cells.

Thus, nucleus is only present is eukaryotic cells.

Answer:

25%

Explanation:

According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.

This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:

30/120 × 100

= 1/4 × 100

= 100/4

= 25% of the selected seeds are infertile.

Answer:

Do Nitrogen, Phosphorus, and Potassium Fertilizers Do for Plants? Nitrogen in Fertilizer. In simple terms, nitrogen promotes plant growth. It is associated with leafy, vegetative growth. Phosphorus in Fertilizer. Phosphorus is involved in the metabolic processes responsible for transferring Each of these fundamental nutrients plays a key role in plant nutrition. Nitrogen is considered to be the most important nutrient, and plants absorb more nitrogen than any other element. Nitrogen is essential to in making sure plants are healthy as they develop and nutritious to eat after they’re harvested. Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.

Explanation: hope im right

Minerals like feldspar and mica are the main suppliers of potassium in soil. The earth provides phosphorus to plants. Usually in the form of synthetic fertilizer or livestock dung, farmers apply phosphorus to soil. The primary source of nitrogen in atmospheric deposition is the combustion of fossil fuels like coal and oil.

Fertilizer, a natural or synthetic substance with chemical components that enhance plant growth and productivity.

The primary sources of potassium in soil are minerals like feldspar and mica. Plants receive phosphorus from the ground.

Farmers add phosphorus to soil, typically in the form of synthetic fertilizer or livestock manure. The burning of fossil fuels like coal and oil is the main cause of nitrogen in the atmosphere.

Plants can take up nitrogen from the soil as [tex]NH^4^+[/tex] and [tex]NO_3[/tex] ions, but most of it is taken up as nitrate due to how common nitrification is in agricultural soils. As plant roots take up water, nitrate readily travels in their direction.

Thus, these are the sources of each of Nitrogen Phosphorus and potassium required for the growth of plant​.

Answer:

In order to be a carrier, the male must be a carrier of the allele without expressing it phenotypically. This can only happen when the inheritance is autosomal because he has a pair of autosomic chromosomes meanwhile he only has one X chromosome. So when the inheritance is X-linked, the allele of the X chromosome will always be phenotypically expressed

Answer:

Yes.

Explanation:

Yes, there is same effects of isotonic, hypotonic, and hypertonic extracellular environments on plant and animal cells because both cells are more similar to each other. If a plant or animal cell is placed in a hypertonic solution, water will go outside the cell, and the cell will shrink, in isotonic environment, there is no water movement inside or outside of the cell, so there is no change in the size of the cell, while on the other hand, if a cell is placed in a hypotonic environment, water will enter the cell, and the cell will turgor.
