Why do you think that dilating blood vessels will decrease temperature of the blood as well as decrease blood pressure?

Answers

Answer 1
Dilation of blood vessels will cause them to be nearer to the skin surface. This means that it will be easier for heat to be lost from the blood vessels to the skin and ultimately to the atmosphere via conduction. This loss in heat reduces the temperature of blood and hence the body temperature in general.
If the rate at which blood is pumped is constant (whether blood vessels are constricted or dilated), then blood pressure decreases when blood vessels are dilated because blood pumped at constant speed has more space to pass resulting in decreased blood pressure.

Global population growth is roughly 83 million people per year, or 1.1 percent per year. From 1 billion in 1800 to 7.9 billion in 2020, the world's population has increased dramatically.

What will be the world's population growth rate in future?The world's population is expected to reach 10.9 billion by 2100 in future, with yearly growth of less than 0.1 percent – a significant decrease from present rates. Between 1950 and today, the world's population increased by 1% to 2% per year, going from 2.5 billion to more than 7.7 billion people.

Hence, the correct option is D.

A tan might indicate sun damage to the skin.

Tanning produces healthier skin.

A tan strengthens the elastic in the skin.

Tanning makes skin look younger.

Answers

Answer:

A tan might indicate sun damage to the skin.

Explanation:

Tanning is the process by which the skin is exposed to the ultraviolet rays that comes from the sun with the purpose of producing a dark-brown coloration called a TAN.

A tan achieved by exposure to the sun can actually indicate that a person's skin is undergoing damage from the UV rays of the sun, hence, the skin responds by producing a protein called melanin, which protects the skin and later forms the dark coloration- tan. From this explanation, tan is got in response to a damaging signal received by the cell, hence, a tan might indicate sun damage to the skin.

Answer:

Explanation:

High pressure, warm temperatures, and high humidity are  factors that creates snow.

What are the factors that create snow?

Snow and/or ice formation requires temperatures below freezing, both in the atmosphere and close to the ground.

Something that will induce the moist air to rise, forming clouds and precipitation, moisture, produces precipitation and clouds.

Water that has frozen solidly is snow, and the atmosphere (layer of gases around Earth) contains water in the form of vapor (gas). When there is a lot of vapor present, clouds develop, fill up with water droplets, and eventually begin to rain.

Therefore, when a very cold water droplet freezes onto a pollen or dust particle in the atmosphere, a snowflake starts to form.

False. Starch is a polysaccharide used as an energy storage molecule in plants, but it is not a component of cell walls.

What are structural component of cell wall?

Cell walls are structural components found in the outermost layers of cells in plants, fungi, and some bacteria. They provide support and protection for the cell, and are composed of a variety of different biomolecules, including cellulose, pectin, and lignin.

Starch, on the other hand, is a complex carbohydrate that is synthesized and stored in the cells of plants, particularly in the seeds, roots, and tubers. It is made up of long chains of glucose molecules and is used by plants as an energy source, particularly during times when the plant does not have access to light for photosynthesis. Starch is not a component of cell walls.

When DNA code changes, what happens to the protein made?

Answers

This occurs when one nucleotide base is substituted for another in a DNA sequence. The change can cause the wrong amino acid to be produced. In some cases, the change has little effect. In other cases, the incorrect amino acid can affect the structure or function of the protein being encoded. A missense mutation is a mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes. Changes in amino acid can be very important in the function of a protein.
