solniwko [45]

Answer:

All the above keywords conclude a process used by plant which is known as photosynthesis. This process is done by all the green plants in the presence of sunlight and also in dark.

Explanation:

Photosynthesis is defined as the process by which all the green plants prepare their food in the presence of sunlight by the use of water, minerals and carbon dioxide. Chloroplast provides green color to the plant and it is also known as photosynthesis site. Glucose is the product and oxygen is a byproduct of photosynthesis.

Calvin cycle is a type of photosynthesis that is also followed by some. the energy released is counted in the terms of ATP which is also known as adenosine triphosphate. Sunlight plays a role of catalyst in the formation of food by the process of photosynthesis

Karolina [17]

Answer:

allopatric speciation.

Explanation:

  • When the population belonging to the same biological species becomes separated from each other due to some geographical factor such that no gene flow can occur between the two separated populations then the speciation that occurs on account of this is known as allopatric speciation.
  • The geographical isolation that separates the two groups can be the origin of a mountain,  the formation of islands, volcanic eruption, etc. which prevents the two groups fro mating with each other and ultimately causes their lineage to speciate.
  • Although the two separate populations are unable to mate due to geographical factors, if the two populations are allowed to mate again, given that they have not been separated very long ago, they can give rise to hybrids.
  • Thus, in the given question it is given that polar bears and grizzly bears have been mated and hybrids have been produced and this points out to the fact that polar bears are result of allopatric speciation.

Why do so many (~30%) gorilla babies die within the first few months of their lives?
katrin2010 [14]

(30%) gorilla babies die within the first few months of their lives because of inherent weakness of the infant or disease.

What is inherited disease?

Genetic factors play a role in almost all health conditions and traits, but there are some conditions in which genetic alterations play a role in almost all of the causes that cause the condition.

Genes are passed from parent to child, so are DNA changes within the gene. DNA changes can also occur spontaneously, first appearing in children of unaffected parents. This is called a new mutation, and the word mutation means change.

Therefore, (30%) gorilla babies die within the first few months of their lives because of inherent weakness of the infant or disease.
