Chimpanzee communication involves different combinations of sounds. What are some examples of these sounds?.

Explanation:

interphase ll, DNA not replicated.

chromosome remain visible.

prophase ll, chromosome move towards the poles.

chromosome thickens.

metaphase ll, chromosome lines up in the middle.

anaphase ll, chromotids move apart.

telophase, nuclear appears .

spindle fibres dissapears.

formation of 4 daughter cells.

According to cell biology, the division of duplicated chromosomes into two new nuclei occurs during the mitotic phase of the cell cycle.

Meiosis is the type of cell division that results in four daughter cells, each with half the number of chromosomes of the parent cell.

Mitosis, the process of cell division, creates genetically identical cells with a constant number of chromosomes. Thus, equational division is another name for mitosis.

Meiosis is broken down into two stages. Several phases are split into each step.

Menopause I:

First phase

I. Metaphase

I. Anaphase

I. Telophase

I. Cytokinesis

2. Meiosis

Telophase II, Prophase II, Metaphase II, Anaphase II, and Cytokinesis II.

One of Lamarck's principle ideas about evolution was that Organisms develop and whatever trait they might acquire is then passed down to their offspring.

Jean-Baptiste Lamarck was an avid supporter of the theories of evolution. He himself gave a lot of theories and principles which he felt were the aptest but only because of the lack of scientific proof to prove him wrong. He proposed that organisms pass whatever traits they have to their offspring.

This notion supports the idea that an individual who develops large muscles due to weight training would have offspring that also have large muscles. This has been proved scientifically wrong now but had quite an impact on the then developing theories of evolution back then.

An increase in respiration rate is a change related to the aging of the respiratory system.

Respiration is defined in physiology as the transfer of oxygen from the external environment to the cells within tissues and the removal of carbon dioxide in the opposite direction, that is, back into the external environment. The biochemical definition of respiration, which refers to a metabolic process through which an organism obtains energy (in the form of ATP and NADPH) by oxidizing nutrients and releasing waste products, differs from the physiological definition. Although cellular respiration and the subsequent maintenance of life in animals depend on physiologic respiration, the two processes are distinct: cellular respiration occurs within individual organism cells, whereas physiologic respiration deals with the diffusion and transport of metabolites between the organism and the external environment.

The network of organs and tissues that aids in breathing is known as the respiratory system. It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs. Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.

Thus from above conclusion we can say that an increase in respiration rate is a change related to the aging of the respiratory system.

The regulation of gene expression after transcription is referred to as post-translational control.

The control of gene expression at the RNA level is known as post-transcriptional regulation. It happens after the RNA polymerase has attached to the promoter of the gene and is synthesizing the nucleotide sequence. The control of active protein levels is referred to as post-translational regulation. There are various types. It is accomplished through either reversible events (posttranslational modifications such as phosphorylation or sequestration) or irreversible events.

It is a disorder of acid-base balance in which there are many acidic components in the blood plasma. It can be caused by some increase in proton generation, because the kidneys are unable to excrete hydrogen, or by loss of bicarbonate from the kidney or intestinal tract.

In the case of the infant, the blood gas report may be due to chronic diarrhea since he is also dehydrated.

Answer:

a. mitosis; the injury would trigger cell division to replace those cells ; results in 2 identical cells

Explanation:

Mitosis is the cell-creation process that an animal would undergo while healing a cut. It is a division that results in two daughter cells. The answer is not binary fission as that is an asexual reproductive method that occurs most often in simple, single-celled organisms like bacteria. It would not be used in the body during the process of healing a cut. The answer is not that it results in 4 identical cells, as mitosis (which is the process used in healing a cut) can only result in 2 identical daughter cells, not four. 4 resulting cells is characteristic of meiosis, which differs from mitosis as each of the 4 daughter cells created in this process are genetically unique and only contain half as much DNA as the parent cell. With these understandings in mind, you can rule out all options other than A.

Earth Tilted Axis

Explanation:

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Answer:

The movement of the earth.

Explanation:

"The earth's spin axis is tilted. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected."

Because the earth is constantly moving/spinning *although slowly*. Depending on where the earth is tilted or what side the sun is pointing to will decided the seasons; as mentioned if the earth's axis is pointed away winter can be expected in the said hemisphere.

How does the nitrogen cycle work? Step 1- Nitrogen Fixation- Special bacteria convert the nitrogen gas (N2 ) to ammonia (NH3) which the plants can use. Step 2- Nitrification- Nitrification is the process that converts the ammonia into nitrite ions which the plants can take in as nutrients.

So even when starting with the first question we know that nitrogen is present in soil BUT the cycle begins during Nitrogen Fixation which plants use.

we also know that the nitrogen cycle has a start-- given I just explained that-- and even though it's continuous there is a point where the cycle repeats and therefore starts again. Knowing it's continuous we also know that when nitrogen 'ends' the cycle simply starts again, and the nitrogen is released back into the air. ("Nitrogen gas [N2] diffuses into the soil from the atmosphere")
