Homeostasis is a state of stable internal environment that is mainteined by an organism. Maintaining the stable temperature (thermoregulation) is one of the examples of maintening the homeostasis and it is achieved by the skin in humans. The skin control of the temperature:
1.sweating- the sweat glands of the dermis secrete sweat that lower the temperature via evaporation,
2. skin circulation-vasoconstriction and vasodilation of the blood vessels inside the skin regulates the temperature. For example, when the body temperature is high, the blood vessels dilate, allowing heat to be released through the surface of the skin,
3. insulation by the subcutaneous layer of the skin which is made of fat cells and fibrous tissue
4.piloerection.
There are 4 ways of the heat loss from the skin:
1.radiation
2.conduction
3.convection
4.evaporation

The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species. Characteristics such as appearance, reproduction, mobility, and functionality are just a few ways in which living organisms are grouped together. These specialized groups are collectively called the classification of living things.
Hope this helps :)
Answer:
the answer is A. Don't expect a explanation because this question is too easy for me to explain . Have a nice day!
Answer:
Crossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.
