How is mRNA or protein synthesis in general related to communication?

Answers

Answer:Three general classes of RNA molecules are involved in expressing the genes encoded within a cell's DNA. Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein synthesis. In eukaryotic cells, each class of RNA has its own polymerase, whereas in prokaryotic cells, a single RNA polymerase synthesizes the different class of RNA. Other types of RNA also exist but are not as well understood, although they appear to play regulatory roles in gene expression and also be involved in protection against invading viruses.

A shipwrecked sailor is stranded on a small desert with not fresh water to drink. He knows he could last without food up to a month, but if he didnt have water to drink he would be dead within a week. Hoping to postpone the inevitable, his thirst drove him to drink the salty seawater. He was dead in two days. Why do you think drinking seawater killed the sailor faster than not drinking any water at all?

Answers

Answer: The salt dried and dehydrated him even further.

Explanation: When we become dehydrated, the sodium concentration in the body is already elevated. Adding salt only aggravates the condition by forcing the kidneys to excrete more water in order to eliminate the extra salt.

proved that dna Carries genetic information

Answers

Answer:

Hope it helps...

Explanation:

The Hershey–Chase experiments were a series of experiments conducted in 1952 by Alfred Hershey and Martha Chase that helped to confirm that DNA is genetic material. Hershey and Chase and subsequent discoveries all served to prove that DNA is the hereditary material.

Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. In eucaryotes, DNA is contained in the cell nucleus.

Dr. Kettlewelll predicted that clean forests would have _____________ colored moths, and polluted forests would have _________ colored moths.

Answers

Answer:

Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.

Dr. Kettlewall predicted that clean forests would have light-colored moths and polluted forests would have dark-colored moths. This is an example of natural selection.

What is natural selection?

Natural selection is a phenomenon in which the fittest individual is chosen by nature. The animal can live and reproduce in that particular environment. An example is the peppered moth population.

The light-colored moths were found on the light-coloured bark, but their population started to decline after the pollution. In the polluted environment, they were easily chosen by predators. So only dark moths survived because they blended in with the polluted environment.

Following the end of the pollution, light colored moth increased again. Predators had a difficult time identifying the light moth because it blended in with the unpolluted environment. Hence, their population increases in unpolluted areas.

Hence, Dr. Kettlewall predicted that a clean forest would have a light-colored moth and a polluted forest would have a dark-colored moth.

PLEASE ANSWER ASAP. Thank you. QUESTION: Explain the evidence that suggests that the universe is expanding.

Answers

One piece of evidence that proves that the universe is expanding is that there is a direct relationship between the speeds of distant galaxies and their distances from Earth. In fact, Hubble discovered that the farther away a galaxy is, the faster it is moving away from us. Although scientists today still don’t know the nature of this mysterious energy causing this acceleration, Hubble’s evidence has strengthened many theories about the large-scale structure of the universe.

Explain why you cannot draw a conclusion about the effect of one variable in an investigation when the other variables are NOT controlled.

Answers

Answer:

Because you don't know which variable caused the effect.

Explanation:

It's always important to have a control because you need to be able to pinpoint exactly what variable caused the specific effect to take place. This is also why multiple variables can not be tested at once.

An organism was found. It is unicellular, but its one cell does contain a nucleus and the cell is autotrophic. What type of organism is this?
A
animalia
B
protista
C
bacteria
D
fungi

Answers

Answer:

B protista

Explanation:

The cell is unicellular, so it can not be an animal, which are all multicellular.

It contains a nucleus, which means it cannot be prokaryotic (it cannot be bacteria)

The cell is autotrophic, which means it cannot be a fungus, which are heterotrophs

Therefore, the organism must be a protist, so the answer is B, protista.
