Well, I need the chart first of all, but second, If you have to find out which one is closely related to A, just take the amino acid sequence and compare the sequence to each organism, and which ever one has the most related sequences, is the closely related organism.

What is the difference between natural selection and selective breeding? Then, give examples of natural selection and selective
serg [7]

Natural Selection is when traits are "naturally" selected for, because "survival of the fitttest."  Example would be a species becoming bigger over time, because the smaller animals of that species were more likely to be eaten by predators.  Natural selection is when the "best" trats are passed down due to chance

Selective breeding is if an outside forece (like a dog breeder) "chooses" a triat to be passed down.  Example, instead of breeding a brown dog with a white dog, the breeder breeds two black dogs together in orer for the litter to all have black fur

mojhsa [17]

Answer:

b. they require more oxygen per unit of volume.

Explanation:

Large animals have a specialized organs for exhalation and inhalation of gases due to the requirement of large amount of oxygen for cellular respiration.

"the medulla, the pons, and the cerebellum are three main parts of the ______."
MA_775_DIABLO [31]

The medulla, pons, and the cerebellum are three main parts of the hindbrain.

Brain is the centre of the nervous system. It is enclosed in the skull cranium. The primary regions of the brain are the forebrain, midbrain and the hindbrain. The forebrain consists of the cerebrum and diencephalon. The midbrain is a small tubular region between the forebrain and the hindbrain. The hindbrain is made up of the medulla oblongata, pons and cerebellum.

Cerebellum is the second largest portion of the brain which helps in maintaining the body's equillibrium, coordinates muscular movements and body posture. Pons is the structure located in the brain stem which relays impulses from medulla to cerebellum and vice versa. Medulla oblongata is the lowest part of the brain stem controlling involuntary reflexes and has the respiratory and cardiac centres in it controlling respiration and heart beats respectively.

Stability mechanism- this happen when individual stabilizes them selves in a particular habitat dealing with

environmental variations that may occur and drift them apart.

Equalizing mechanism - they all try to be at the same pace to avoid been out compete, even though some are stronger they equalize their energy for all to manage the limited resources.
