Answer:
To keep the earth safe and clean
Explanation:
If we keep the ocean clean then the water creaters will be able to live better, I mean how would you feel if someone was putting trash in your home., not so good huh. if you recycle your stuff like paper then frewer trees are cut down, yes they do plant one tree every time they take one, but it takes years for the oxygen to rebuild to the same leave, and without trees, not co2 and oxygen.
It is quite possible that introducing a new predator to the food chain may set it off balance. The cougar will flourish in southern Alabama based on the circumstances given above because of the high availability of deer. The introduction of the cougar will decrease the deer population overall.
Hope this helps in some way!
If I remember that abiotic means not living then rocks, soil, air.
The answer regarding the components of an arthropod's nervous system would be item C. It consists of brain, nerve chord, and ganglia. The brain is located dorsally, while the nerve cord together with the ganglia is ventrally structured — extending on each segment of an arthropod’s body.
Answer:
A. Yes, because the %A approximately equals the %T and the %G approximately equals the %C in both species.
Explanation:
According to Chargaff's rule, in all cellular DNAs, the number of adenosine residues (A) is equal to the number of thymidine residues (T). And the number of guanosine residues (G) is equal to the number of cytidine residues (C). Therefore, the sum of the purine residues equals the sum of the pyrimidine residues (A+ G= C+ T). It is based on the fact that a purine base always pairs with a pyrimidine base in a double helix DNA.
Chargaff’s rule is followed in all the double-helical DNA molecules irrespective of the species. In DNAs of sea urchin and salmon, the percentage of adenine is equal to that of the thymine and the percentage of guanine is equal to that of the cytosine. Therefore, Chargaff's rule is followed.
