animal cells are classified into two main types. which ones? multiple select question. stem cells embryonic cells somatic cells non-stem cells germ-line cells adult cells

Answer:

not

Explanation:

If the egg of a particular butterfly has 14 chromosome, then the somatic cells will have same 14 chromosomes.

A somatic cell, also known as a vegetal cell, is any biological cell other than a gamete, germ cell, gametocyte, or undifferentiated stem cell that forms the body of a multicellular organism.

These cells make up the body of an organism and divide via binary fission and mitotic division.

Mitosis is a cell division process that produces somatic cells. They have two copies of each chromosome, one from the mother and one from the father. Diploid cells usually have two copies each of each chromosome.

Mitosis is the method by which one cell splits into two genetically identical daughter cells.

The cell's chromosomes are copied and then distributed evenly between the two new nuclei of the daughter cells during the various stages of mitosis.

Thus, as these are somatic cells, they will have same number of chromosomes.

Option 1 is Correct. Genetic material crosses over when it moves from one chromosome to a nonhomologous chromosome.

When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place. Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up. The same genes may be present on the two chromosomes in different versions.

The exchange of genetic material across homologous chromosomes is known as crossing-over. New gene combinations are created on each chromosome as a result. Homologous chromosomes are randomly allocated to daughter cells during cell division during meiosis, whereas distinct chromosomes segregate apart from one another.

The adrenal glands are responsible for the general adaption syndrome's non-specific physiological reactions to stress.

The Canadian scientist Hans Selye developed the term "general adaptation syndrome" (GAS) to characterise the body's reaction to stress. The alert stage, the resistance stage, and the weariness stage are the three stages of the GAS, according to Selye. Namely, the adrenal cortex generates the hormone cortisol, which raises blood sugar levels and inhibits the immune system, and the adrenal medulla produces adrenaline (epinephrine), which triggers the "fight or flight" response.

Hence, the glands that generate the general adaptation syndrome's nonspecific physiologic reactions under stress are:

If all diseases were completely removed from the body, it would result in a state of optimal health. Without the presence of diseases, the body would be able to function at its full potential, and there would be no symptoms or negative effects caused by illnesses.

This would lead to improved overall well-being, increased energy levels, and enhanced physical and mental functioning. Removing diseases from the body would also mean that the immune system is no longer burdened with fighting off infections or managing chronic conditions. The immune system could focus on maintaining normal physiological functions and protecting the body from potential future infections or threats. However, it is important to note that the complete absence of diseases is not a realistic or attainable goal in most cases. The human body is constantly exposed to various pathogens and environmental factors that can lead to the development of diseases. While it is possible to prevent and manage certain diseases through healthy lifestyle choices and medical interventions, eliminating all diseases entirely may not be feasible.

Afterload is the cardiac factor which indicates the increased work experienced by the heart and leads to increasing blood pressure.

The afterload is basically defined as the amount of pressure which the heart needs to exert in order to eject the blood during ventricular contraction. This is pressure is recorded as the systolic pressure of the heart.

Any changes in the afterload of the heart happen to affect the stroke volume, end-diastolic volume, end-systolic volume, and left ventricular end-diastolic pressure. An increased afterload indicates an increase in the work that is experienced by the heart and leads to an increase in the blood pressure. With aging, an increase in systolic blood pressure is observed and also a widened pulse pressure.

Answer:

The source of energy that drives the water cycle is C. Sunlight.

Explanation:

The source of energy that drives the water cycle is C. Sunlight.

The sun's energy causes water to evaporate from oceans, lakes, and other bodies of water, forming water vapor that rises into the atmosphere. As the water vapor cools and condenses into clouds, it releases heat energy, which helps to power atmospheric circulation and weather patterns. When the clouds release precipitation in the form of rain or snow, the water returns to the surface and the cycle starts again.

So, the sun's energy is the primary driver of the water cycle.

It cannot change individuals. This is because it happens over many generations. E.g. Peppered moths camouflage with bark. Black moths do not, so they are easily seen by predators. The black moths are eaten because they do not have a desirable trait for survival. The black moths cannot then pass on the trait for black wings to their offspring. However, the peppered moths can pass on their trait for peppered wings to their offspring. Overtime, the population of black moths will decrease and most of the population will have peppered wings. The trait for peppered moths will be present even after many generations and black moths will be rare.
