Answer:

Archaea and eukaryotes are very closely related than bacteria and eukaryotes. because both archaea and bacteria responsible for the formation of more complex cells

Explanation:

It has been believed for many years that archaea and eukaryotic cells are genetically related to a developmental process that involves the production of eukaryotic cells by archaea development.
At the same time, scientists believe that archaea have more to do with eukaryotic cells than bacteria.
This is because research shows that bacteria are also closely related to eukaryotic cells, meaning that along with archaea, bacteria are part of the evolutionary process that makes up these cells.

A scientist studied a population of birds for 10 years. During that time, the population was never fewer than 30 birds and never

ahrayia [7]

Answer:

A particular population limiting factor or factors must have been removed

Explanation:

The population of the birds must have been kept between 30 and 50 individuals by population limiting factors such as the presence of predators within the community or competition for resources such as food or spaces.

For the population to shoot up to 90 all of a sudden, it may be that one or more of the population limiting factors has been removed from the population. It could be that a major predator has been removed from the community or the competition for food/space is now significantly reduced due to more food/space in the community.

A medical test indicates that a patient has a defective protein. This

OleMash [197]

Answer:

number of nitrogen bases

Explanation:

The correct answer would be the number of nitrogen bases.

A defective protein is usually caused by mutation, which is defined a change in the DNA sequence of an organism.

Mutation can occur in a variety of ways including:

1. Deletion of nucleotide base sequence in the DNA

2. Addition (insertion) of nucleotide base sequence in the DNA

3. Duplication of nucleotide sequence in the DNA

A change in number of phosphate molecules, sequence of subunits DNA and sequence of sugar molecules if possible in nature, do not lead to mutation if the change does not affect the sequence of DNA.

Hence, the correct option is number of nitrogen bases.
