Genetically identical armadillos were kept in the same controlled environment from birth and provided the same diet. Even though
Vlada [557]

Phenotypic variations in genetically identical organisms that grow in the same controlled environment may be due to mutation.

<h3>Mutation</h3>

This refers to a sudden change to the DNA sequence of living organisms.

When the DNA base sequence of organisms changes, the effect is shown in the morphology of organisms.

For organisms that are genetically identical but grow in different environments, phenotypic variations might exist as a result of environmentally acquired traits during the struggle to adapt to their environments.

In the same environment, however, genetically identical organisms are not expected to be phenotypically different, unless a mutation to the DNA of one has occurred.

Identify whether the following statements are true or false.
Advocard [28]

The True statements are.

Organisms in a population must compete for the resources as the resources are limited and the organism that compete and survives wins.

The best equipped organism survive which is known as the survival of the fittest.

Over the time due to challenges in the environment the beneficial variation takes place in the organisms and it spreads through the generations and then it gradually changes the whole population.

The false statement is Organism of the same species are equipped with the same survival skills.

The organism of the same species have some variation and because of this variation they compete and win against the other member of the same species.

The concept of endosymbiosis (chloroplast &amp; mitochondria) is widely accepted. What kind of relationship is it?
melamori03 [73]

Answer:

mutualistic

Explanation:

The interaction between two organisms in which both the organism gets benefitted from each other is called a mutualistic relationship. This mutualistic relationship is seen in the concept of endosymbiosis.

According to the endosymbiotic theory chloroplast and mitochondria are evolved by engulfment of different bacteria by ancestral cells. Then these bacterial remained in a mutualistic relationship with each other and the ancestral cell evolved into a eukaryotic cell.

So as mitochondria and chloroplast live with a symbiotic relationship with eukaryotic cells, therefore, it is considered as mutualistic relationship.
