Breast milk composition and frequency of demand feedings separate a carrying species from a nesting species.
<h3>What does patterns of parental care mean?</h3>
The patterns of parental care can be defined as stimuli that shape the relationship between parent and offspring in different species.
Carrying species are those species where parent care do not involve building nests for their offspring (conversely to nesting species).
In conclusion, breast and demand feedings separate a carrying species from a nesting species.

The process is when the magma cools and make crystals
Answer:B
Explanation:
Selective breeding is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males

<h3>What is a anaerobic respiration?</h3>
Anaerobic respiration is respiration which occurs in the absence of oxygen.
Oxygen is used as an electron acceptor during respiration. However, when oxygen is absent or insufficient, other molecules are used as electron acceptors in order to produce energy.
Anaerobic respiration in large organisms may result in the formation of lactate known as lactic acid fermentation.
In lactic acid fermentation, after glycolysis, the two pyruvate molecules receive hydrogen atoms from NADH creating lactic acid. Lactic acid can be converted back into pyruvate in the liver. The pyruvate can then enter into the mitochondria and cellular respiration, can proceed.
On the other hand, anaerobic respiration in microorganisms produce ethanol and is known as ethanol fermentation.
After glycolysis, the two pyruvate molecules lose a CO₂ atom, creating acetyl CoA. The acetyl CoA atom combines with hydrogen to form acetaldehyde. Acetaldehyde receives a hydrogen atom from NADH, resulting in the production of ethanol.
In conclusion, anaerobic respiration can occur either as a lactate fermentation or ethanol fermentation.
