Answer: Capillaries
Explanation:
Capillaries are the thin-walled blood vessels that connect arteries to veins. They are essential for the distribution of oxygenated blood from arteries to the tissues and carrying back deoxygenated blood towards the heart. Capillaries, which are about 120 angstroms in diameter, also facilitate the exchange of nutrients, oxygen, and waste products between the blood and cells.
The thin-walled blood vessels that connect arteries to veins are called capillaries. Capillaries are the smallest and thinnest of the blood vessels in the body and they serve to distribute oxygenated blood from arteries to the tissues. After oxygen is used by these tissues, the deoxygenated blood is then carried back towards the heart by veins.
Because capillaries are so thin, they allow the exchange of nutrients, oxygen, and waste products between blood and the cells. With a diameter of about 5 to 10 micrometers, they are just about 120 angstroms, which is wide enough for blood cells to pass in single file. Capillaries are a crucial part of the circulatory system and are found throughout the body, making up a large part of the body's total blood vessels.

Homologous chromosomes are two similar chromosomes that an individual inherits from their parents. They contain identical gene segments in the same locations, determining specific characteristics or traits. For an example, different gene sequences in these chromosomes determine a trait like human blood type.
Two similar chromosomes you inherit from your parents are called homologous chromosomes. These matched pairs of chromosomes within a diploid organism are the same length and have specific nucleotide segments, called genes, at the same location. These genes, which are found on the homologous chromosomes, determine specific characteristics by coding for specific proteins, also known as traits.
One chromosome of a homologous pair is inherited from each parent. For instance, human blood type, a certain trait, is determined by three possible gene sequences (A, B, O) that can be found on these chromosomes.

Global warming can be affected by deforestation because the removal of tress affects the level of carbon dioxide in the environment. The level of carbon dioxide increase with a decrease in the number of trees that cause global warming.
Further Explanation:
The deforestation or the removal of vegetation from the shore can result in soil erosion. The soil erosion will result in the loss of nutrients rich soil. These nutrients are essential for the development of algae and plants. Global warming is a serious concern because of two reasons: Rapid warming of the Earth leads to rapid environmental changes making it difficult for species to adapt. Over time, natural habitats have become limited because of the resilience to climatic changes caused by global warming. The increased human population leading to urbanization and deforestation resulted in these changes. The increase in the human population leads to an increase in their needs for survival. They started to disrupt the food chains by removing predators. They hunted animals for food and other needs. They removed trees for their shelter. These human activities lead to a change in the environment and habitat.
