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.
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.

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

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
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.
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?
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.
There is an enzyme in your stomach. Explain how the enzyme would be affected if it was moved
the small intestines.
Answer:
It might not work as efficiently because the conditions are different
Explanation:
The stomach is highly acidic compared to the small intestine. That means the pH is higher in the small intestine. Stomach enzymes are adapted to work at low pH, but might not work at a higher pH as in the small intestine. They might not be able to efficiently catalyze reactions in the small intestine.
