Which statement best describes the role of DNA in relation to RNA and proteins? A.
DNA is made from RNA, which is created from proteins.

B.
Proteins are made from RNA, which is created from DNA.

C.
RNA is made from DNA, which is created from proteins.

D.
Proteins are made from DNA, which is created from RNA.

Answers

The DNA, RNA and Proteins. DNA or other wise called deoxyribonucleic acid is the building block of the life. It contains the information the cell requires to synthesize protein and to replicate itself, to be short it is the storage repository for the information that is required for any cell to function.
c. RNA is made from DNA, which is created by proteins.

Diffusion, Osmosis and EnzymesThe diffusion of water from a high concentration to a low concentration
Lowers the amount of energy needed to perform chemical reactions
When you breath O2 passes into your blood stream while CO2 passes out of your blood stream
Involved with, but does not become a part of chemical reactions
Small molecules with no charge can move through semi-permeable membranes by this process
a. Enzymes
b. Simple Diffusion
c. Enzymes
d. Simple Diffusion
e. Osmosis

These are to match up

Answers

The given statements can be matched as following:

a)The diffusion of water from a high concentration to a low concentration  - Osmosis

b)Lowers the amount of energy needed to perform chemical reactions- Enzymes

c)When you breath O2 passes into your blood stream while CO2 passes out of your blood stream-Simple Diffusion

d)Involved with, but does not become a part of chemical reactions-Enzymes

e)Small molecules with no charge can move through semi-permeable membranes by this process-Simple Diffusion

Explanation:

a) Osmosis is generally defined as the process by which water is transported from a region of Higher concentration to the region of Lower concentration.

b) Enzymes are well known to reduce the amount of energy required or needed for a chemical reaction to take place.

c)The process by which oxygen passes through our blood stream and carbondioxide passes through the other is known as simple diffusion process.

d) Enzymes are ones that actively gets involved in the chemical reaction but they will never become a part of that chemical reaction.

e) Diffusion is the process by which very small molecules that carries no charge moves through semi permeable membrane.

What does reproductive isolation within a species cause?A. A decrease in genetic drift
B. A decrease in gene flow
C. An increase in gene flow
D. an increase in genetic drift

Answers

Reproductive isolation within a species causes is an increase in gene flow. The correct option is C.

What is reproductive isolation?

Reproduction isolation is a mechanism constituted by some factors like behavior, physiological process, etc. by which the species does not reproduce with other species.

Gene flow is the flow of genes in forward generations, and reproduction isolation increase the gene flow within species.

Thus, option C. An increase in gene flow is correct.

Will give brainlist HELP ASAPOmnivores carnivores herbivores and decomposers are all consumers. True or false?

Answers

Answer:

True

Explanation:

Carnivores that eat herbivores are called secondary consumers, and carnivores that eat other carnivores are called tertiary consumers. Animals and people who eat both animals and plants are called omnivores. Then there are decomposers (bacteria, fungi, and even some worms), which feed on decaying matter.

In 1967 a penicillin-resistant pneumonia, caused by Streptococcus pneumoniae and called pneumococcus, surfaced in a remote village in Papua, New Guinea. At about the same time American military personnel in southeast Asia were acquiring penicillin-resistant gonorrhea from prostitutes. By 1976, when the soldiers had come home, they brought the new strain of gonorrhea with them and physicians had to find new drugs to treat it. In 1983 a hospital-acquired intestinal infection caused by the bacterium Enterococcus faecium joined the list of bacteria that could not be killed by penicillin.Which of these BEST describes why certain bacteria have become resistant to penicillin?A) The penicillin in the 1970's was much weaker that the penicillin used today, thus it was not as effective. B) Penicillin was not effective in treating any bacterial diseases, so the doctors had to find new treatments. C) These new bacterial strains came out of the jungles and forests already equipped to be penicillin-resistant. D) Penicillin was so heavily prescribed by doctors that it led to certain, more fit, strains of bacteria to be able to survive. 2)
