Which of the following do all cells in a multicellular organism have in common?1. They all express the same genes.

2. They all have the same proteins.

3. They all have the same mRNA.

4. They all have the same DNA.

Answers

The correct answer is (d) They all have the same DNA.

  • All the multicellular organisms have same DNA but the different parts of the body has different gene expression.
  • For example: the same DNA is found in the cells of kidney and liver, but the gene expression for liver results in large number of hepatocytes and the same DNA in the kidney will give rise to nephrons.
  • This proves that all the cells in the multicellular organisms have same DNA but their expression of protein in different cells are different.

A plant will wilt if it does not have enough water in the ____ of its cells My choices I have are nucleus, lysosomes, central vacuole, or golgi apparatus

Answers

Central vacuole. That is the part of the plant that stores most of the water. It is the really large sac you can see in plant cells but  you don't see it in animal cells:) 

According to the biological species concept, for speciation to occur, _____. according to the biological species concept, for speciation to occur, _____. the number of chromosomes in the gene pool must change large numbers of genes that affect numerous phenotypic traits must change at least one gene, affecting at least one phenotypic trait, must change changes to centromere location or chromosome size must occur within the gene pool

Answers

The answer is; at least one gene, affecting at least one phenotypic trait, must change

This change, due to mutation, may result in an extreme trait in a small proportion of the population . If this extreme trait proves to be favorable with the environment it will continue to increase in the population with every generation. Eventually, the trait will become common in most individuals and the population will have speciated.


How do the light-dependent reactions and light-independent reactions work together?

Answers

Answer:

In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. ... In addition, several enzymes of the light-independent reactions are activated by light.

Elements produce their spectrum when their electrons _____. are in the ground state move away from the ground state move toward the ground state all of the above

Answers

The best answer to the question that is being presented above would be 'move toward the ground state'. Elements produce their spectrum when their electrons move toward the ground state. All the other choices do not fit the blank space provided.

Answer:

Option C, move toward the ground state

Explanation:

When electron of an element move from a region of ground state to a region of high energy, it absorbs certain amount of energy. Now, when this electron starts moving from its excited stage to its ground stage it emits energy in the form of eigen states that vibrates with certain frequency just like the vibration of violin.

A spectrum is a distributed set of frequency and wavelength which corresponds to these eigen states

Hence otpion C is correct

What had the instructions to make proteins in the cell

Answers
