What are some questions that biologists might ask about the living things they study?

Answers

Answer:

What are some questions that biologists might ask about the living things they study?

Explanation:

Five fundamental questions in biology ...

1) The origin of life.

2) The mechanisms of evolution.

3) The control of the size, both of the organs and of the living beings.

4) The functioning of the brain.

5) Aging.

Biologists might ask some questions about the living organisms they study. These questions include, but not limited to:

  • What group of living organism do they belong to? Is it a plant, animal, protozoan, fungi or moneran?
  • How complex is the organisms' body? is it multicellular or unicellular?
  • How do the organisms feed? is autotrophic or heterotrophic?
  • How do the organisms reproduce? sexual, asexual, or both?
  • How do the organisms get energy? aerobic or anaerobic?
  • How do the organisms move?
  • How do the organisms grow?
  • How do the organisms get rid of waste products from their systems?
  • How long do the organisms live? What is their life cycle like?
  • How do they interact with the biotic and abiotic components of their environments?
  • What kind of habitats do they live?
  • What role do they perform in their habitats?

All these questions and more might be asked by Biologists about the living organisms they study.

What is a potential outcome if one of your father's gametes did not go through meiosis correctly and one of the chromosomes did not separate correctly? You inherited a normal amount of genetic material from your mother but inherited an extra chromosome from your father. One of your pairs of chromosomes will not be homologous. You inherited an abnormal amount of genetic material from both your mother and father. One of your pairs of chromosomes will not be homologous. You inherited a normal amount of genetic material from your mother but inherited an extra chromosome from your father. Two of your pairs of chromosomes will not be homologous. You inherited a normal amount of genetic material from both your mother and father resulting in the inheritance of a normal amount of genetic material.

Answers

Answer:

You inherited a normal amount of genetic material from your mother but inherited an extra chromosome from your father.

Explanation:

It seems logical because if you think about it. If one of your father's gametes were made incorectly and you got it you could come out looking deformed or you can have something extra.

Please let me know if I'm wrong.

PLS HELP I’m not sure which one it is lol

Answers

Answer:

Option B)

Explanation:

A moon is a celestial body that revolves around a planet.

The others are wrong because, a planet orbits around the sun, not the sun orbiting the planet.

A meteor does not have a fixed orbit, and asteroids orbit around the star near it, in our case, the asteroid belt orbits the sun.

Choose from the list the molecules necessary for every living thing on earth to survive. Select one or more: a. Lipids b. Carbohydrates c. Phosphate d. Nucleic Acids e. Proteins f. Oxygen ( :

Answers

Final answer:

Every living thing requires lipids, carbohydrates, nucleic acids and proteins for survival and proper functioning. These are the biological macromolecules that carry out crucial functions such as energy provision, genetic instruction, and various metabolic reactions.

Explanation:

All living things require certain molecules to survive and function. These molecules include Lipids, Carbohydrates, Nucleic Acids, and Proteins. Lipids are fats that provide long-term energy storage and insulation. Carbohydrates are the body’s main source of energy. Nucleic Acids such as DNA and RNA contain the genetic instructions for the development, function, growth, and reproduction of living organisms. Proteins perform a vast array of functions within organisms, including catalyzing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another. Phosphate and oxygen, while also essential to life, are technically not molecules but atoms or ions involved in various biological processes.

Where does the RNA cap go? The tail?

Answers

Answer:

The post-transcriptional modifications in the mRNA produced as a result of the transcription in eukaryotes provide many advantages to the mRNA.

The two post-transcriptional modifications are the addition of  7-methylguanosine cap at 5' end of mRNA called capping whereas the addition of the poly(Adenyl) tail at 3' end called tailing.

The advantages of capping are:

1. Protection of nascent mRNA from the degradation.

2. Recognition by transcription factors helps in translation.

The advantages of tailing are:

1. Protection of the mRNA from enzymatic degradation in the cytosol.

2. Transcription termination

3. Export of the mRNA from the nucleus
