B. Today's plethora of microorganisms is the result of an extremely brief period of genetic recombination events.
C. Mutations function to prevent the offspring of an organism from evolving.
D. Random, heritable genetic mutations are a source of genetic variation. This variation is necessary for natural selection to occur.
The statement which is true regarding genes and evolution is as follows:
Thus, the correct option is D.
Genetic mutation may be defined as sudden, stable, and inheritable alterations in the genetic material of an organism. It is considered one of the most useful events for evolution to occur.
Random mutation takes time but they are the least effective and non-influential. Such type of mutations are easily heritable and induces genetic variation among individuals of the same species.
As a result of this, as time passes such mutations become a base for natural selection to occur and allow the favorable variation to survive and reproduce effectively.
Therefore, the correct option for this question is D.

Answer:
the answer is D! :)
Explanation:
Answer: The correct answer for the blank is-
a description of a trait or habitat.
According to the binomial system of classification, living organisms can be named scientifically, using two words. The first word in the scientific name of the organism corresponds to the Genus and the second word/ part is the species to which the organism belongs. The second part that is the species depicts the description of a trait or habitat.
For example- Scientific name for Human beings is Homo sapiens, which shows that they belong to species 'sapiens' that gives description of human beings.
Thus, first option is the right answer.
Answer:
Messenger mRNA: contains the genetic blueprint to make proteins.
Transfer TRNA: They translate mRNA into proteins. They carry amino acids on its third aceptor site to a ribosome complex.
Ribosome rRNA: They form ribosomes essential in protein synthesis.

Answer:
All invertebrates except echinoderms are protostomes. Protostomes include the phylum: coelenterata, ctenophora, platyhelminths, nematyhelminths, annelida, arthropoda and mollusca.
Explanation:
Echinoderms and chordates have tube within tube type of body plan which has evolved along deuterostomic evolutionary line. Other similarities between echinoderms and chordates (which includes vertebrates) are:
-They possess a true coelom called enterocoelom.
- They have mesodermal skeleton made of calcareous plates or ossicles.
It differs due to the life cycle of each tree, and the very specific way the trees go.
