In the early 1900s a scientist hypothesized a link between DNA and the production of proteins in the cytoplasm. However, the fac

t that DNA could not be found outside the nucleus led scientists to believe that another substance was also involved in the synthesis of protein in the cytoplasm. In the 1940s scientists performed an experiment that ultimately identified the site of protein synthesis. They also identified the molecule responsible for transporting information form the nucleus to the site of protein synthesis. What was this newly identified molecule? A) A gene B) mRNA C) ATP D) Thymine

Let us go over the definitions and the functions of each term:
a) Gene is a bit vague but in general it means a part of DNA that encodes one protein. Genes are the building blocks of our genomes but not the answer to this question.
b)mRNA. This is correct. The name itself means messengerRNA and its role is to copy the genetic information in the nucleus and bring it outside to be translated into protein.
c) ATP is an important molecule in our metabolism; energy is stored in this molecule and then used. It has no relationship to the mechanisms concerning DNA.
d) Thymine is one of the 4 nucleotide bases that are found in DNA, the other three being guanine, cytosine and adenine. They are essential components of a nucleotide (building blocks of DNA and RNA) but again, they do not transfer information out of the nucleus.

A zoologist analyzes the jawbones of an extinct mammal and concludes that it was an herbivore. The zoologist most likely came to this conclusion based on the shape of the teeth.

Animals that consume plants, such as deer, elephants, cows, and many others, are known as herbivores. They eat a range of vegetables, fruits, grasses, grains, and other foods depending on the habitat of the specific animal, hence they are essentially vegetarians.

The broad, flat teeth of herbivores are perfect for chopping up the plant material they consume. These animals' teeth enable them to break down the fibers in their food, making it much simpler for them to digest.

Plant-eating animals known as herbivores have large, flat molars and sharp incisors. They don't own any dogs. The incisors, canines, and molars of omnivores are used for a range of foods. The teeth of herbivores are designed to crush and ground vegetation.

To learn more about herbivores refer to:

Of the 200 to 400 million sperm cells released in a typical ejaculation, approximately how many do you think will reach the ovum
Travka [436]
Only 200 out of 2 000, 000 sperm cells reach the ovum. And only one (in exception to very rare cases of two) sperm cells actually participate in the process of fertilization. In comparison, an average female only produces 400 of egg cells during their lifetime, but the eggs cells are significantly larger than sperm cells.

Most of the atp supplies for a skeletal muscle undergoing one hour of sustained exercise come from _____.
ioda

The question is incomplete as it does not have the options which are:

A) creatine phosphate.

B) glycolysis.

C) substrate phosphorylation.

D) oxidative phosphorylation.

E) de novo synthesis.

Answer:

D) oxidative phosphorylation.

Explanation:

The ATP is the energy molecule which provides energy to every metabolic process in the organism.

The ATP in humans is produced by a process called cellular respiration where the last phase of the process called electron transport chain produces the highest amount of protein. The electron transport chain is also known as the oxidative phosphorylation as the oxygen is gained and electrons are lost during the phase.

Thus, D) oxidative phosphorylation is correct.
