Answer:
closely related
Explanation:
DNA, RNA, and protein are all closely related. DNA contains the information necessary for encoding proteins, although it does not produce proteins directly. RNA carries the information from the DNA and transforms that information into proteins that perform most cellular functions.

These antibiotics include penicillin and its derivatives and work by inhibiting the production of the bacterial enzymes.
What is Penicillin's mechanism of action?
The Penicillium mold is the source of penicillin, one of the first and still-commonly-used antibiotics. The numerous mold species that produce different types of penicillin ; the naturally occurring penicillins (those produced during the fermentation process of mold) and the semi-synthetic penicillins are two categories into which penicillium can be categorized.
All penicillins function in the same way, which is to inhibit the bacterial enzymes necessary for the creation of cell walls in replicating microorganisms and to activate other enzymes that demolish the microorganism's protective wall. They are therefore only effective against microbes that are actively forming cell walls and multiplying, and they are likewise safe for use on human cells.

B)
C)
E)
F)
Answer:
F)
Explanation:
Animals are multicellular organisms (that's why we can see them) with a nucleus containing DNA. They consume other organisms. This means they are heterotrophs. Animal cells don't have cell walls. If you look at its cell, there is no cell wall visible. This eliminates options B, C, and E. So, option F would represent animals.

Answer:
C, that a sedimentary layer is 100 million years old.
Explanation:
The law of superposition functions without regard to exact times, basing its times relative to the layer above or below it. Without the age of a specific layer being giver in advance, you will not be able to determine the specific age of the layer being examined, only a relative age.

When a protein is subjected to unusual environmental circumstances, it undergoes denaturation, which is a physical change. Proteins can be denatured by heat, acid, strong acids, alcohol, mechanical agitation, and high salt concentrations.
What are the main cause of enzyme denaturation?pH and temperature. When an organism is at its ideal temperature, enzymes work best. This temperature in the human body is 37 °C. Only up to a certain degree do enzyme activity and reaction rates rise slightly with temperature.

Which term refers to the energy an object has due to its position? A Electrical energy B. Potential energy C. Thermal energy D. Kinetic energy
Answer:
Option B
Explanation:
Using the process of elimination, we will find this answer.
It's not option A because electrical energy involves electricity and has nothing to do with motion/position, although you can build machines fueled on electrical energy to create motion or position. (Hence; vehicles)
It is option B because potential energy is energy the object has when it's at rest, which means when the object remains in the same position it has potential energy.
It's not option C because thermal energy involves heat which you could use heat energy and convert it into electrical and then build a machine that is fueled on electrical energy that creates motion or position. (Hence; boats)
It's not option D because Kinetic energy is purely energy when a object is in motion, has nothing to do with a position of a object. As long as the object is moving it has kinetic energy.
Your answer is option B or "potential energy."

A man has type A blood and his wife has type B blood. A physician types the blood of their four children and is amazed to find one of each of the four blood types. He is not familiar with genetics and calls upon you to explain how such a thing could happen. What would you say? Explain using a description of the parental allele possibilities.
Answer:
Explanation:
There's nothing to get amazed to find all the four types of blood groups in the progeny, provided the parental genotypes are AO and BO.
The four types of blood groups included A, B, AB and O.
Had the parental genotypes been AO and BO, the progeny would include all the four blood groups A with genotype AO, B with genotype BO, AB with genotype AB and O with genotype OO.
It happens only in this case and not in any other as the alleles A and B are co dominant to each other and completely dominant over the allele O.

Today, biologists classify organisms primarily by their
Group of answer choices
a.DNA.
b.All choices are correct.
c.behavioral differences.
d.Appearances only.
Answer:
It's DNA.
Explanation:
DNA is the most recent utility to determine the origin of an organism and it's powers compared to it't weaknesses.
Nowadays, it is the primary tool:
Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
An organism with a genome of about 50,000,000 base pairs is found to have faulty dna repair proteins, even though its dna polymerase still proofreads while replicating the dna. About how many point mutations would you expect in this genome after two rounds of dna replication?.
Based on the error rate of 1 in 10000 nucleotides, the number of point mutations is 1000 mutations.
What is DNA repair?DNA repair is the method where errors which occur during DNA replication are corrected.
During DNA replication, the error rate is approximately 1 error for every 10,000 nucleotides copied.
This rate is reduced to only 1 error for every 1 billion nucleotides by DNA repair proteins.
Since the DNA repair proteins of the organism are faulty, the error rate is 1 in 10000.
Number of nucleotides copied = 2 × 50,000,000 = 100,000,00
Number of errors = 100,000,00/10,000 = 1000 point mutations
Therefore, the number of point mutations is 1000 mutations.

B.
They find fossils of animals that died suddenly.
C.
They find a sudden disappearance of many fossil species.
D.
They find evidence of changes in the Earth's atmosphere.
Answer:
C.
They find a sudden disappearance of many fossil species.
Explanation:
A mass extinction is usually defined as a loss of about three quarters of all species in existence across the entire Earth over a “short” geological period of time. Given the vast amount of time since life first evolved on the planet, “short” is defined as anything less than 2.8 million years.
