Why are fungi fossils so rare?
Volgvan
The reason as to why fungi fossils seem so rare is that they are usually microscopic and often difficult or impossible to identify. Not much information on fungi fossils has been documented. This could be because fungi fruiting bodies consist of soft, fleshy and easily degradable tissues which due to their poor integrity do not keep or preserve as well as animal tissue. Even when available, it takes a trained eye to recognize fungal fossils. Not many people have the training and expertise to recognize the fossils.

Explain the stages of tissue repair and fill in the blanks.
svp [43]

Answer:

a. Following an injury that breaks the surface of the skin. blood vessels dilate as a result of histamine release from mast cells and other damaged cells.

b. The blood forms a clot and upon drying, a scab forms a barriers between the body and the environment, while phagocytes work to clear the underlying debris from the wound site.

c. Blood vessels begin to re-grow into the wound while fibroblasts begin process of replacing the blood clot with Collagen

d. The remodeling phase then occurs as fibrosis and regeneration of tissues may continue for prolonged period of time.

Explanation:

Hello. Although you did not have all the answer options for the blanks presented in the sentences above, it is possible to conclude that the words in bold are the most appropriate to fill these spaces.

That's because when we cut ourselves, the blood vessels on the surface of our skin rapidly dilate, allowing a flow of blood to be observed. This dilation is accomplished by the release of histamine, which is released by mast cells, which are glands that regulate the immune response. At this point, it is important that any impuzera or microorganism, close to the wound site, is removed and this site undergoes cleaning. This is done by phagocytes, which are intended to prevent the cut from becoming the entrance to a bacterial infection.

Then the blood vessels begin to move and grow again across the wound, with the aim of covering this opening. In this comment, fibroblasts begin to apply collagen and replace the blood clot formed to prevent blood loss. Collagen will be responsible for maintaining the skin and tissues that will be rebuilt in the remodeling phase.

When gas molecules begin to clump together in molecular cloud they increase the
Schach [20]

At the center of the cloud, more weight of the gas molecules are present.

The mass or weight at the center of the cloud increases when the gas molecules group together in a molecular cloud because more gas molecules are present at the center which combines with each other leads to heavier weight of gas molecules. The combination of gas molecules make the center of the molecular cloud denser as compared to other parts of the cloud so we can conclude that increase in mass occur at the center of the cloud.
