describe how the skin works when the place is very hot
Answers
Answer:
when body temperature rises, such as when exercising on a hot day, the dermal blood vessels will dilate, in the sweat glands begin to secrete more sweat. the invaporation of the sweat from the surface of the skin cools the body by dissipating heat.
Explanation:
Hope this helped Mark BRAINLEST!!!
Answer:
When it is hot, we normally sweat. Sweating removes the heat energy from our skin. Our blood vessels open up which lets more blood flow. This allows a way for the heat to be lost. It lets your body cool down or try and cool down.
In the presence of oxygen, all cells synthesize ATP via the process of glycolysis. Many cells also can metabolize pyruvate if oxygen is not present, via the process of --
Answers
Answer:The option are not given, here are the options gotten from another website.
A. Aerobic respiration
B. Electron Transport Chain
C. Anaerobic respiration
D. Krebs cycle
The correct option is C.
Explanation:
This is because anaerobic respiration is a type of respiration that produced ATP. pyruvate are metabolize in the absence of oxygen by a process called fermentation and fermentation us anaerobic respiration. And fermentation is the chemical process where glucose or substrates are broken down in the absence of oxygen by the activities of enzymes. When pyruvate are metabolize in the absence of oxygen , it will produce lactate.
In the presence of oxygen, all cells synthesize ATP via the process of glycolysis. Many cells also can metabolize pyruvate if oxygen is not present, via the process of fermentation.
In biology, an incomplete oxidation process is called fermentation, which does not require oxygen to take place, and which produces an organic substance as a result.
Fermentation consists of a process of glycolysis (breakdown of the glucose molecule) that produces pyruvate (pyruvic acid).
As it lacks oxygen as a receptor for the excess electrons of the NADH produced (nicotin adenine dinucleotide), it uses an organic substance that must be reduced to reoxidize the NADH to NAD +, finally obtaining a derivative of the initial substrate that is oxidized.
In this process, then, neither the mitochondria nor the structures linked to the cellular respiration process are involved.Only 2 molecules of ATP are produced per molecule of glucose consumed.It is carried out by the muscle cells that ferment glucose when the oxygen input is not enough to continue breathing.Therefore, we can conclude that many cells also can metabolize pyruvate if oxygen is not present, via the process of fermentation.

Which of the following is an advantage of meiosis and sexual reproduction?
A. Meiosis ensures that offspring will not inherit any genetic disorders.
B. Meiosis ensures that offspring are genetically identical as their parents.
C. Meiosis ensures that offspring will have identical phenotypes to their parents.
D. Meiosis ensures a wider variety of genetic variation.

Answer:
D. Meiosis ensures a wider variety of genetic variation.
This happens above all thanks to the Crossing over, the process in which the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids results in recombinant chromosomes.

If too many pandas are competing for bamboo (their food), what could happen?
Answers
Answer:
The correct answer would be - eventually, there will no be enough bamboo for all.
Explanation:
Competition for a single resource usually results in the scarce of the particular resource and eventually, there will be no resources in the end. In this case, it is given that there is too many Panda in a particular area competes for bamboo.
Due to this competition, there will be less bamboo initially, and eventually, there will be not enough bamboo for all the pandas. The correct answer will be - eventually, there will no be enough bamboo for all.
dichotomous key of a cockroach
Answers
Answer:
Identification of cockroaches is limited here to adults. A major source of confusion is the recognition of adults from nymphs.There are subjective differences, as well as morphological differences. Immature cockroaches are known as nymphs. Nymphs closely resemble adults except nymphs are generally smaller and lack wings and genital openings or copulatory appendages at the tip of their abdomen. Many species, however, have wingless adult females. Nymphs of these may be recognized by their shorter, relatively broad cerci and lack of external genitalia. Male cockroaches possess styli in addition to paired cerci. Styli arise from the subgenital plate and are generally conspicuous, but may also be reduced in some species. Styli are absent in adult females and nymphs

Answers
Anaphase I of meiosis in shown in this image.
What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase.
