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.
G . because the bat population will change with no bugs.
Answer:
The correct answer will be option-C
Explanation:
The plant absorbs the sunlight to perform photosynthesis which helps produce the sugar molecule used by the plants.
The plants absorb maximum sunlight at two wavelengths that are red and blue wavelength by chlorophyll and other pigments. The efficiency of photosynthesis is also measured maximum at these two active wavelengths called action spectrum.
In the given question, since the efficiency of photosynthesis has been discussed which could be measured with the production of oxygen and consumption of carbon dioxide. The experiment performed by the Engelmann showed that aerobic bacteria got concentrated in the blue and red wavelengths as the output of the photosynthesis were observed maximum.
Thus, the selected option is the correct answer.
Answer: The length of the cell in millimetres is 0.0015.
Explanation:
Given conversion :
Thus 
Given : Length of the cell = 1.5 micrometers 
To find: Length of the cell in milllimeters (mm)
Length of the cell in milllimeters (mm) = 
The length of the cell in millimetres is 0.0015.
The respiratory system is a collection of organs involved in carrying out gas exchange in your body. Deep in the lungs, tiny sacs called alveoli take in oxygen from the atmosphere and release carbon dioxide.
