Explain how is it possible that when you look at the nice guy he may be looking at stars for millions of years ago

Biology
1 answer:
USPshnik [31]3 years ago
8 0

Answer:

The reason is because it takes a long time for the light from the stars in the sky to reach earth, so the light the star was producing millions of years ago has just now reached Earth.

Hope this helped! :)

What do many scientists believe about the purpose for asteroids.
katovenus [111]

Answer:

Various scientists describe asteroids in different ways:

  • Some scientists consider it to be rocks which orbit around the sun.
  • Other consider it to be small planets.

The majority of the scientists agree that asteroids might have come into existence at the time of solar formation. The parts which broke down during the formation of the solar system resulted in the formation of asteroids.

<u><em>Scientists believe that asteroids might not have a major function in the universe but studying them would be of great benefit. This is because as they are parts broken from the solar system, exploring them will let us know about some unknown features of the other solar system bodies. </em></u>

4) Explain the term "endoskeleton". 5) What is an exoskeleton?​
Elena-2011 [213]

Answer:

Below

4) An endoskeleton is an internal skeleton made out of mineralized tissue that is attached to muscles as well as enabling movement.

5) An exoskeleton is the external skeleton that supports and protects an animal's body. As an example, a snail's shell is an exoskeleton

Meiosis ensures the transmission of traits from one generation to the next. At the same time, it is a key process that introduce
liraira [26]

The question is incorrect so the answer consists of the genetic context of meiosis.

Answer:

Two main types of cell division are mitosis and meiosis. Meiosis is the process of cell cycle division in which the parents cell divides into the four daughter cells. This division is also known as reductional division.

In meiosis, the gametes are haploid where as the parent cell is diploid in nature. The cell undergoes the two meiosis division, the first division is reductional in nature whereas the second meiosis division is same as the mitotic division. This division occurs in the sex cells and results in the formation of haploid gamete hat restores deiploidy during fertilization process. Crossing over during meiosis bring variation in the cells.

In the area with the largest sea lamprey population, what is being done to reduce this population?
victus00 [196]
In the area with the largest sea lamprey population, a few things are done to reduce and control this population. Lampricide, Currently, the primary method to control sea lampreys utilizes a lampricide, called TFM, that kills sea lamprey larvae in streams with little or no impact on other fish.   Barriers,Barriers have been constructed to block the upstream migration of spawning sea lampreys; most barriers allow other fish to pass with minimal disruption. Barriers have eliminated lampricide treatment on some streams and reduced the stream distance requiring treatment on others. The Sterile-Male-Release-Technique, The sterile-male-release-technique aims to reduce the success of sea lamprey spawning. Each year male sea lampreys are collected and sterilized. When they are released back into streams the sterile males compete with normal males for spawning females. Lastly trapping, Sea lamprey traps are operated at various locations throughout the Great Lakes, often in association with barriers. Traps are designed to catch lampreys as they travel upstream to spawn.

In prokaryotes, how does the length of a typical monocistronic mRNA compare to the length of the protein generated from this mRN
Nastasia [14]

1. The correct answer is: a. There are more mRNA bases than amino acids.

The transcription of monocistronic mRNA in prokaryotes is a rare process (it is more characteristic for the eukaryotes). Monocistronic mRNA is RNA, which encodes for only one or specific protein. Three bases of mRNA encode one amino acid of protein, thus it has more bases than amino acids of the final product, protein.  

2. The correct statements are:  

The mRNA contains 5' and 3' untranslated regions.

The stop codon does not code for an amino acid.

The start site of transcription is upstream of the start codon.

Each codon contains 3 RNA bases.

All of these approve that more bases are in mRNA since not all of them are translated into amin oacids.

Other statements are hallmarks of eukaryotic RNA processing, and therefore not relevant to prokaryotes.
