What tells the cell what to do

Answers

Answer 1
Answer: The DNA does. DNA ( deoxyribonucleic acid) is the controller molecule of cells. It gives the codes for protein production, it determines when the cell will divide etc.
Answer 2
Answer: The nucleus is like the control center

After an RNA molecule is transcribed from a eukaryotic gene, portions called _____ are removed and the remaining _____ are spliced together to produce an mRNA molecule with a continuous coding sequence.a. operators ... promotersb. exons ... intronsc. introns ... exonsd. silencers ... enhancerse. promoters ... operators

Answers

Answer:  Portions called introns are removed and the remaining exons are spliced together

Explanation:

The messenger RNA obtained after transcription is known as primary transcribed RNA or precursor RNA, and it has to undergo modifications before exerting its function. This is called RNA processing or maturation.

In the DNA sequence, the coding content of a gene is not continuously distributed along the gene, but has discontinuities, called introns, whose sequence does not encode proteins.The parts of the sequence that encode proteins are called exons. Through a process called splicing (which is one of the modification that are part of the RNA maduration), the introns are eliminated and the exons are joined forming a mature messenger RNA molecule that will be used for protein synthesis.

So the exons are part of the region of a gene that is not separated during the cutting and splicing process and is therefore kept in the mature messenger RNA. Each exon codes a specific portion of the entire protein, so that the set of exons forms the coding region of the gene.

A student is drawing a model of the carbon cycle. Which caption should he include to explain how herbivores contribute to the carbon cycle from the food they eat?

Answers

Answer:

Cellular respiration

Explanation:

Herbivores are organisms that feed on plant materials solely. They are usually animals like sheep, cattle, goats with four stomach compartments. They are part of the global carbon cycle which shows how carbon is circulated in nature.

  • Plant matter is broken down by herbivores through a series of metabolic steps.
  • The final product is a glucose laden material which is the raw material needed for cellular respiration.
  • When oxygen combines with the glucose, energy is liberated, and carbon dioxide, a waste product is released into the atmosphere.
  • This way, carbon is cycled in the ecosystem.

Answer:

Herbivores eat plants, producing carbon dioxide during cellular respiration that is released into the atmosphere.

Environmental designers design structures to match the environment.
a. True
b. False

Answers

The statement above is TRUE; environmental designers design structures to match the environment.

Environmental design is the act of building useful infrastructures while taking the environmental parameters into consideration. Environmental designers refer to professional such as architects, interior designers, etc, who construct different types of structures. Environmental designers usually carry out their work in such a way that they maximize the environmental parameters that are available. For example, in ancient Greece people built their houses in such a way that it faces the direction of the sun. This is done in order to maximize the energy of the sun for solar heating in the houses. Environmental designers also take care to cause minimum damage to the environment when they are engage in construction.

a. True. They create structures that match the environment so that humans do the least amount of damage to it.

Which object in space emits light because it releases energy produced by nuclear fusion?

Answers


My answer to this would be the sun

Final answer:

The Sun is the object in space that emits light due to the energy released from nuclear fusion in its core. This process involves the fusion of hydrogen nuclei to form helium, releasing energy as photons, neutrinos, and gamma rays. The released energy, particularly the photons, is therefore responsible for the Sun's light.

Explanation:

The object in space that emits light because it releases energy produced by nuclear fusion is the Sun. This nuclear fusion takes place in the Sun’s core and involves the combination of two hydrogen nuclei to form helium, releasing energy in the process. This energy is released as light and other particles such as neutrinos and gamma rays.

In detail, the nuclear fusion reaction in the Sun converts about 10³8 protons per second into helium at a temperature of 14 million Kelvin. The energy produced manifests as photons (light), neutrinos, and other particles. The neutrinos and gamma rays escape the Sun's core and propagate out into space.

The energy from this nuclear fusion diffuses slowly towards the surface of the Sun, lighting up the Sun and ultimately, our Earth. It's worth noting that though this process destroys mass, the amount of energy release, known as the Q value, is incredibly large, affirming the application of Einstein's mass-energy equivalence principle, E=mc².

As a result of the absence of plants in the meadow, the rabbit population will probably

Answers

are there any multiple choices?
anyways, without the multiple choices, the answer will probably be; decrease.
Explanation: a meadow is a field or pasture; a piece of land covered or                            cultivated with grass, usually near a river.
                     Rabbits need lots of water and vegetables, so a meadow is                        usually the best habitat for them. 
                     When the meadow is ruined (plants decrease), their habitat                        is ruined, causing them (the rabbits) to slowly decrease.
                     They could decrease as a result of their death, as a result of                       their migration to a different and more suitable place, or as a                      result of both. Usually, though, it is both, since when animals                      start to die, their species start to move away from that                                  location.
