The tree creates a layer known as the abscission layer, which prevents nutrients and water from reaching the tree and inhibits the growth of the leaves. Hormones in the trees cause the process of abscission.

Tiny tubules in the abscission layer are responsible for carrying carbohydrates back into the tree and delivering water to the leaf, flower, or fruit.

The amount of nutrients and water that pass through the tubes is decreased in the autumn because cells in the abscission start to expand and exude a waxy substance.

Abscission of leaves, which takes place in the fall, is the natural loss of an old leaf at the base of the petiole. Many physical and biochemical changes occur during leaf abscission, most of which are controlled by plant hormones.

Therefore, every fall that the trees in the forest lose their leaves.

Answer:

The correct answer is - phagocytosis.

Explanation:

Phagocytosis is a type of endocytosis that also engulfs the solid material including microbial pathogens like bacteria and others. In immunity response macrophages, neutrophils and. immature dendritic cells are white blood cells that perform the phagocytosis process to kill the microbes and antigens.

Phagocytosis ingests and digest pathogens and develops an adaptive immune response an essential part of the innate immune system. WBC will most likely take it in through phagocytosis in the given case.

Explanation:

Earth's magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are ripped off by solar winds.

D) A population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season

Based on Darwin's ideas, a population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season (Option D).

According to Darwin, evolution can be defined as descendence with modification, which mainly occurs via natural selection.

Answer:

Natural processes are interactions among plants, animals, and the environment. These interactions, which include photosynthesis, pollination, decomposition, and others, help create and shape natural communities.

Explanation:

A natural resource is the winds, which are produced by the displacement of atmospheric air.

Examples of renewable natural resources:

Renewable natural resources are those that are renewed in nature, existing in abundance. Typically, these resources do not run out easily due to the renewal time and their ease of renewal.

With this information, we can conclude that there are several types of natural resources, with different forms of formation.

Answer:

D. Increased availability of food

Explanation:

Trust

The factor that would increase an area's carrying capacity for black-footed ferrets is the increased availability of food. The correct option is D.

Carrying capacity is defined as the average population size of a species in a given habitat.

Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.

If there is more food available in an area, more black-footed ferrets can survive and reproduce, increasing the species' carrying capacity.

Increased competition for space, more diseases, and more predators would all reduce the carrying capacity of black-footed ferrets by reducing the number of individuals that could survive and reproduce in the area.

Thus, the correct option is D.

Answer:

The only cells that aren't considered somatic cells in the body is the reproductive cells.

Answer:

A. HH - tall head, Hh - tall head, hh - short head

B. 75% or 3/4

C. 25% or 1/4

Explanation:

Paul and Penelope are heterozygous for their tall head, which means they have one dominant and one recessive allele. So, their genotype is Hh.

When crossed, the results are 1 HH - h0m0zygous dominant tall head, 2 Hh - heterozygous tall head, and 1 hh - h0m0zygous recessive short head.

So, there is a 75% of a child with a tall head and a 25% chance of a child with a short head.

Hope that helps.

Answer:

Griffith's experiment, reported in 1928 by Frederick Griffith, was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation. Griffith's findings were followed by research in the late 1930s and early 40s that isolated DNA as the material that communicated this genetic information.

Griffith's experiment discovering the "transforming principle" in pneumococcus bacteria.

Pneumonia was a serious cause of death in the wake of the post-WWI Spanish influenza pandemic, and Griffith was studying the possibility of creating a vaccine. Griffith used two strains of pneumococcus (Streptococcus pneumoniae) bacteria which infect mice – a type III-S (smooth) which was virulent, and a type II-R (rough) strain which was nonvirulent. The III-S strain synthesized a polysaccharide capsule that protected itself from the host's immune system, resulting in the death of the host, while the II-R strain did not have that protective capsule and was defeated by the host's immune system. A German bacteriologist, Fred Neufeld, had discovered the three pneumococcal types (Types I, II, and III) and discovered the quellung reaction to identify them in vitro. Until Griffith's experiment, bacteriologists believed that the types were fixed and unchangeable, from one generation to another.

In this experiment, bacteria from the III-S strain were killed by heat, and their remains were added to II-R strain bacteria. While neither alone harmed the mice, the combination was able to kill its host. Griffith was also able to isolate both live II-R and live III-S strains of pneumococcus from the blood of these dead mice. Griffith concluded that the type II-R had been "transformed" into the lethal III-S strain by a "transforming principle" that was somehow part of the dead III-S strain bacteria.

Completing the attached chart about the three main research projects ;

All three researches were carried out to discover the genetic material ( DNA ) which is responsible for the transfer of genetic traits from parent cells to daughter cells.

Griffith research shows that bacterias can get there DNA ( genetic material ) through a process known as transformation and the experiment to prove this research was carried out by killing S bacterias through heat and then adding them to R-strain bacteria. Griffith observed and concluded that the Genetic materials of the S bacteria was taken up by the S -bacterias through a process known as " transforming principle "

During Avery research for the genetic material ( DNA ) Avery treated a mixture with DNA-destroying enzymes to see if the colonies of the mixture will transform but they failed to transform which proves that proteins are not the transforming factors and that DNA is the genetic material.

Hence we can conclude that Completing the attached chart about the three main research projects is as written above.
