The phagocytotic barrier, which is a part of innate immunity best describes the above scenario.
Answer: Option C
<u>Explanation:</u>
The largest organ of the body is the skin, similarly the skin also an immune barrier to the body. If there is any damage in the skin , its pH gets compromised and there it calls in for a microbial attack.
When there is a cut in the skin and bacteria enter the body, the immune system responds. First, macrophages approach the area of the cut. Next, the macrophages surround any bacterial cells and engulf them, the Phagocytosis barrier which is the part of the innate immunity
Some examples of physical properties are:
color (intensive)
density (intensive)
volume (extensive)
mass (extensive)
boiling point (intensive): the temperature at which a substance boils.
melting point (intensive): the temperature at which a substance melts.
Hope this helped!!!XD
Answer:
Through a chemical process called "condensation". The addition of the two molecules typically proceeds in a step-wise fashion to the addition product, usually in equilibrium, and with loss of a water molecule.

The types of evidence for evolution include
i) Changes in allele frequency over subsequent generations.
ii) When the population in question is examined it does not follow Hardy-Weiberg equilibrium.
iii) Signs of gene flow between populations.
iv) Presence of Sewall-Wright effects or genetic drift in the population.
