How do vasoconstriction and vasodilation contribute to the homeostasis of body temperature ?​

Answers

Answer 1
Blood vessels, which lead to the skin capillaries, become narrower they constrict which allows less blood to flow through the skin and conserve the core body temperature. This is called vasoconstriction.

What do you think which cell will be moving a sprem cell or an egg cell and why?​

Answers

Explanation:

sprem cell will move Ok because it has high potential

Each sperm cell, or spermatozoon, is small and motile. The spermatozoon has a flagellum, which is a tail-shaped structure that allows the cell to propel and move. In contrast, each egg cell, or ovum, is relatively large and non-motile. During fertilization, a spermatozoon and ovum unite to form a new diploid organism.

Natural selection is the concept of genes being picked out of the gene pool due to an organisms ability to survive. Animals who instinctually or physically are able to live longer produce more offspring, therefore its genes get passed down. Over a long period of time that strain of genes may very well be common in a species having the ones who aren’t able to adapt be the minority or extinct. Artificial selection is when a human specifically breeds certain traits in an organism for a function or aesthetic, like dogs for example. The dachshund was bred to hunt badgers because of their narrow body, they can crawl into burrows.

Rapid glacial retreat due to climate change.

The disturbances, which can only be categorized as extreme, are the rapid glacial retreat due to climate change.

What is the glacial retreat?

The glacial retreat is when the terminal does not extend as far.

When the ice melts quicker than the snow falls, the retreat of glacial occurs.

When the glacier loses its ice more it gains, than water level rises.

Sometimes, the pieces of ice rocks float in between the water.

Thus, the correct option is D.

3. How can mutations benefit a species?

Answers

Answer: They can lead to speciation.

Explanation: Speciation can introduce new survival traits to a species which can lead to higher survival rate in their environment and that can lead to population growth.

Answer:

They result in specific gene variants that aid organisms in adapting to environmental changes. Beneficial mutations are required for evolution to take place. They improve an organism's chances of survival or reproduction, and as a result, they are likely to become more frequent over time.

They do not move.


They move backwards.

Answers

Water waves are an example of waves that involve a combination of both longitudinal and transverse motions. As a wave travels through the waver, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water increases. The animation at right shows a water wave travelling from left to right in a region where the depth of the water is greater than the wavelength of the waves. I have identified two particles in orange to show that each particle indeed travels in a clockwise circle as the wave passes.
