1)The answer is D.

Thorns are an adaptation that some plants have evolved in order to discourage herbivore from eating the plant. Plants would try to survive when there are environmental pressures (herbivores eating them in this case) so they would evolve to have thorns.

It is not A because bigger leafs (more surface area for absorbing the sunlight) would help plants produce more food from photosynthesis, not thorns.

It's not B because it is an adaptation, not JUST mutation, but it did happen from changing some letters in the DNA sequence to evolve.

It's not C because thorns doesn't help conserve resources from getting used by others. The thorns of cactus decreases the loss of water from the sunlight because it is normally in the desert so it can survive, not protect resources.

Free palmitate is activated to it's coA derivative(palmitoyl-CoA) in the cytosol before it can be oxidized in the mitochondria.
n200080 [17]

Answer: hydrolysis of intermediate palmitoyl Co A ,with loss of labeled CoA.before reaching the matrix gives the answer

Explanation:

This is because when the labeled Coenzyme A of the Plamitate combines as Palmitoy-CoA with oxaloacetate to form intermediate (palmitoyl-CoA )in Citric Acid cycle:

CoA is hydrolysed with loss of the labelled CoA which returns to the cystosol. Therefore, the labelled CoA does not reach the matrix of the mitochondrial,but returns to the Cystosol.

Consequently, the CoA in the Cystosol will be labelled in palmitoylCoA and the one in the matrix of the liver mitochondrial will be non radioactive(,will not labelled).

in a series of experiments Griffith infected mi've with oa nonvirulent r strain bacteria and highly virulent s strain bacteria.
Andrej [43]

Answer:

This demonstrate the transforming principle.

Explanation:

Griffith performed the experiment on the virulent bacteria and non- virulent bacteria. The non- virulent bacteria produce rough colonies and did  not cause pneumonia. The virulent bacteria produces smooth colonies that kill the mice and caused pneumonia.

When Griffith mixed the on virulent bacteria and heat killed virulent bacteria he found that the mice were killed. He concluded that there was transforming principle that turns the non- virulent bacteria into virulent bacteria from the heat killed bacteria. Something, has been transferred from the heat killed bacteria to the non- virulent bacteria. Later, he found that dead mice blood sample contained both the non-virulent rough bacteria strains and virulent smooth strains of bacteria.

  • Autotroph uses energy from the inorganic chemical reactions and light.
  • Heterotrophs depend upon the other nutrition sources because they cannot produce on their own.
