translating the code contained by the DNA into the proteins the cell needs for structure and function
Answer:
El nucleolo
Explanation:
El nucleolo es una región del núcleo celular que se ocupa de la producción y ensamblaje de los ribosomas de las células. Tras el montaje, los ribosomas son transportados al citoplasma de la célula donde sirven como centros de síntesis de las proteínas.

why virus is imortal?
Answer:
Strictly speaking, viruses can't die, for the simple reason that they aren't alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can't thrive independently. Instead, they must invade a host organism and hijack its genetic instructions.
Explanation:
Answer:
A flu is a virus and the reason that you have to get flu shots every year is because every time a virus enters a host it is mutated by the antibodies, cells and biology of that host, so it can be passed on to another host who may not be immune to every part of this NEW virus.
Explanation:
So your answer is both yes and no.
Imagine a glucose molecule entering the cell membrane. Would that
molecule be able to reach the mitochondria faster if the cell had a smaller
volume or a larger volume? Explain.
Answer: THE TRANSPORT OF A MOLECULE FROM THE CELL MEMBRANE TO THE MITOCHONDRIA WOULD BE FASTER IN A CELL WITH A SMALLER VOLUME BECAUSE THERE WOULD BE LESS DISTANCE TO TRAVEL
Explanation:
I hope this helped
Glucose is a simple sugar that constitutes of carbon, hydrogen and oxygen atoms. It is the most abounding monosaccharide out of all the carbohydrates.
The glucose molecule will move actively to the mitochondria from the cell membrane if the membrane has a smaller volume.
The reason for the answer is:
Smaller the cell size less will be the covering space, hence the molecule will move less distance to reach its target.Mitochondria uses glucose molecules and generates carbon dioxide as the waste material.It is not always beneficial for the cell to be larger sometimes smaller cells can be more dynamic.Therefore, the glucose molecule will travel faster when the cell membrane has a small volume.

explain what natural selection is and how it occurs
Answer:
Natural selection is when an animal adapts to their environment to survive and produces more offspring. It occurs when the animal isn’t thriving in their environment and they make adaptions to where they can survive.
Explanation:
An example of natural selection is, a bird used to have a really thick and short beak. But to have more access to food they adapted to their environment and now have a long and skinny beak.

Which principle states that two species in the same habitat cannot have the same niche?
niche exclusion principle
competitive exclusion principle
habitat exclusion principle
population exclusion principle
Answer:
competitive
Explanation:
example 1: two male bucks cannot inhabit the same habitat or area because one needs all the females or pride for itself so it chases away the others
The competitive exclusion principle explains that two species occupying the same niche cannot coexist in the long term since competition is created between them for resources.
What is the competitive exclusion principle?It is a phenomenon that refers to the competition that one species has with another and the dependence of one organism to develop in terms of the other organism.
In competitive exclusion, one species is displaced by another when their niches overlap and compete for the same resources.
Therefore, we can conclude that the competitive exclusion principle establishes that two species that have the same ecological needs cannot live together since they create competition between them for resources.

significance of sexual reproduction
please answer fast
Answer:
Sexual reproduction is the process in which male and female gamete fuse to form zygote through a process called fertilization and it is important for plants as it provides variation to the progeny that helps in the better survival and help it to gain its own uniqueness within the species and remove the unwanted genes and lower the risk of getting a disease
Answer:
Sexual reproduction leads to variation which provides protection as different organisms will be more prone to different things
Emission lines are lines that are made when wavelengths of light are given off by cooling gases.
O True
O False
Answer:
Its FALSE on edge
Explanation:
When cooling gases emit light wavelengths, lines known as emission lines are created. The first people to notice constellations were the ancient Romans and Greeks.
What Emission lines that are made when wavelengths light?Monochromatic light has a single wavelength and is generated by lasers, which exploit transitions between two atomic energy levels to generate light with an extremely restricted range of wavelengths.
While emission lines refer to the lines of light produced by burning hot gas, absorption lines refer to the tendency of cool ambient gas to absorb the same lines of light.
Some light at specific wavelengths is scattered when it travels through the atmosphere's gas, producing darker bands.
Therefore, It is false that Emission lines are lines that are made when wavelengths of light are given off by cooling gases.
