I think it’s D because less carbon would normally be produced in the absence of sunlight. Also, less energy would be present if no sunlight is there
One example that science would not be able to test
I often hear the comment, "Science has proved there is no God." Don't ever be bullied by such a statement. Science is completely incapable of proving such a thing.
I'm not saying that because I don't like science, but rather because I know a little about how science works. Science operates on induction. The inductive method entails searching out things in the world and drawing generalized conclusions about those things based on observation. Scientists can only draw conclusions on what they find, not on what they can't find.Science can prove that this is a god .A god that created the earth
Peritrichous refers to the bacteria having flagella all over the surface of the bacteria. The monotrichous bacteria have only one flagella. The phototaxis refers to the movement of the bacteria towards and away from the light. The movement of bacteria towards or away from a chemical stimulus is referred as chemotaxis.
Hormones are called chemical
messenger of the body, which occur in various tissues where they are produce. They
occur in response to specific biochemical signals from a wide range of
regulatory systems and behavioral activities that is vital in the communication
between organs and tissues. Moreover, hormones create a cellular response by
binding to cell membrane or intercellular receptors.

Answer:
C. a mutation in the genetic code.
Explanation:
A mutation refers to any change or alteration to the nucleotide sequence of a gene caused by mutagen or mistakes during replication. Depending on the manner of occurrence, mutation can be of different types. In this question, partial DNA sequence for normal hemoglobin is given as: G-G-A-C-T-T-C-T-T while the partial DNA sequence for sickle cell anaemia is given as: G-G-A-C-A-T-C-T-T.
From careful observation of the two two DNA sequences above, it can be realized that a SUBSTITUTION MUTATION from T to A has occurred in the sequence of sickle cell. Note that substitution mutation is the replacement of one base by another in a sequence.
