Well first off, Mendel’s law of segregation states that individuals possess two alleles and a parent passes only one allele to his/her offspring. Mendel’s law of independent assortment states the inheritance of one pair of factors (genes) is independent of the inheritance of the other pair. Now Mendel discovered this through his little experiment with the pea plants that showed certain traits through a particular pattern, subsequently becoming the foundation of modern genetics and heredity.
Answer:
they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.
The walls of the alveoli are only one cell thick. This makes the exchange surface very thin - shortening the diffusion distance across which gases have to move. Each alveolus is surrounded by blood capillaries which ensure a good blood supply.Adaptations of the alveoli:
Thin walls - alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through.

Have great day
The mouth is the beginning of the digestive tract. In fact, digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use. Hope I’ve helped ;)
Answer:
It is called Parathyroid hormone
Parathyroid hormone, also called parathormone or parathyrin, is a peptide hormone secreted by the parathyroid glands that regulates the serum calcium concentration through its effects on bone, kidney, and intestine.
<span>The answer is anulus fibrosus.
</span>
The intervertebral disk is located between vertebrae. It is has two parts, the middle part which is called nucleus polposus and the outer part, the <span>Anulus Fibrosus. This outer part, </span>is a strong fibrous tissue in the form of a ring, that can withstand compressive forces.
