The question is incomplete as it does not have the option which are:
Answer:
Primates A and B are more closely related to each other than either is to primate C.
Explanation:
In the given question, on the basis of the given information, it can be predicted that the Primate A and B are more closely related to C as the DNA sequences of these two primates are almost similar. The similarity of the sequence suggests that these primates have descended or diverged from a common ancestor.
The DNA sequence of C is different from both A and B which shows that both A and B are different from the C.
Thus, the selected option is the correct answer.
Answer:
The DNA sequencing is important for the determination of the evolutionary relationship with the organisms. The ancestory and descendants can also be identified by DNA sequencing.
Three primates A,B and C DNA sequences has been identified. It is given that primates A and B has same sequence and they are more closely related with each other. The primates C is unique and do not share relation with the primates A and B.
b. C4H10
c. C4H4
d. C4H6
A hydrocarbon consists of four carbon atoms with one double bond. Predict the molecular formula of this compound.
the awnser would be c4h8
B. Catalase
C. Chlorophyll
D. Hemoglobin
E. RNA polymerase
B. contains enzymes that begin the breakdown of proteins
C. moistens food and aids in compacting of the bolus
D. dissolves food chemicals so they can be tasted
Saliva cleanses the mouth, moistens and compacts food, and dissolves food chemicals for taste.
Saliva is a clear liquid that is produced by the salivary glands in the mouth. It serves several important functions in the digestive process. It keeps the mouth clean by cleansing it and helps to remove food particles. Saliva moistens food and aids in the compacting of the food into a bolus, which can be easily swallowed. Additionally, saliva contains enzymes such as amylase that begin the breakdown of carbohydrates, not proteins. Lastly, saliva dissolves food chemicals so they can be tasted.

Answer:
C. When exposed to antibiotics, most bacteria in a population die but some survive and live to reproduce.
Explanation:
Darwin suggested natural selection as the mechanism that explained the evolution of species. This idea states that a population of individuals living in a certain environment is adapted to thrive in it. However, if there is a change in the environment, individuals must adapt in order to survive, otherwise they will die. Only a handful of individuals which had a particular (and random) variation before the change of the envirnonment will be able to adapt and survive. If the variation is heritable, the next generation will have that same trait and will be able to thrive in the new environment.
In the answer C., a population of bacteria is composed of some individuals which are susceptible to the antibiotic and some individuals that are resistand because they possess a mutation in their DNA that allows them to survive an environment with antibiotics. If no antibiotic is present, then both types of bacteria can survive. However, if they are exposed to the antibiotic, the previously resistant bacteria are the only ones that will be able to survive and reproduce.
