In mammals, alveoli is the region inside lungs where gaseous exchange occur between pulmonary blood and atmosphere.
Answer:
Answer is Option C.
The concentration of organic molecules by the process of dehydration synthesis can facilitate their assembly into macro molecules.
Explanation:
Macromolecules are large molecules formed by covalent bonds between monomers. They are a growing chain of monomers assemble through a process called dehydration synthesis in which one monomer forms a covalent bond with another monomer by releasing a water molecule. This is a process that requires energy. For example, two glucose molecules (monomers) combine to form a single maltose molecule. As a new covalent bond forms between the two glucose molecules, a water molecule is released.
Evaporation is a process in which water vapor is formed from water. The tendency of dissimilar particles to stick together is known as adhesion.

1. They have a nucleus which serves a great function in many cellular activities. <span>Nucleus,
the control center of the cell is the organelle which intiates,
enables, and manages the various simplex. compound and complex cellular
activities. It also stores the DNA of the cell which is then replicated
and recopied over a hundredth and thousandth times over through cell
division processes. In the nucleoplasm -nucleolus, the inner part of
nucleus of a cell is where the DNA to mRNA and to protein; vice-versa
happens. <span>

Answer:
8. pulmonary veins, 2. left atrium, 4. left ventricle, 6. aorta,
5. venae cavae, 1. right atrium, 3. right ventricle, 7. pulmonary trunk
Explanation:
The heart maintains the flow of blood with the help of veins and arteries. The pulmonary veins transfers oxygenated blood from lungs to left atrium that contracts and releases blood into left ventricle and further to aorta and then to the body.
The deoxygenated blood transfers from the venae cavae to right atrium that contracts and releases blood to right ventricle. It transfers blood to pulmonary trunk which divides to pulmonary arteries that flows deoxygenated blood to lungs for oxygenation.
Answer:
I think the answer is A. They are different species, therefore their niches do not overlap and they do not compete.
Explanation:
I hope this helps!
