Answer:
Fossils provide direct evidence of evolution. They show the changes of animals from ancient organisms to present form. Fossils are the preserved remains of earth layers. There are 4 types of fossils-
Original fossils that are not very old. e.g. teeth, skeleton, shells.
Frozen fossils
less permanent fossils
casts, molds, and prints - wings, skin, leaves, etc.
The fossils show the adaptive radiation in horses, humans. The transition fossils form the connecting link between different groups such as fish and amphibians, reptiles and birds, etc.
e.g. Archeopteryx is the connecting link between the reptiles and birds.
The modern horse Equus have several ancestor species, we came to know from the fossil records.
The fossil record shows the evolution of humans and their ancestors.

Answer:
Soil is the basic requirement for any plant or microorganism(that lives on land) to grow and get all the required amount of nutrients from the environment. Because, when a seed is planted inside a specific amount of soil it grows and develop in to a bud having its initial structure well set for having roots at one end and stem at the other, however the soil provides the bud the main protection and support which is required to balance its structure in a proper way or orientation.
As, there are different layers of soil and each layers consists of a different level or amount of components in it and provides different specification to the over all development of plant life.
Explanation:
- Along, with that there are different level of nutrients inside the different samples of soil taken from various regions or areas which makes it more different in nature to support life and give it a chance to grow or develop itself in it. As different species of plant life requires a more different form minerals and constituents to grow in which brings diversity among plant life, as not all of them requires the same sample of soil to grow in.
- Having, the specific structure of molecules in it, the soil also acts as a barrier for the plant life to save it self from any foreign object or pathogen.
It is likely that the light blue colonies have a mutation in GENE I (lacI gene). LacI (lactose inhibitor) is a DNA-binding factor that represses transcription of the lac operon.
The lacI gene (regulatory gene for lac operon) is a gene located upstream of the three genes of the lac operon (i.e., lacZ, lacY, and lacA), which are transcribed as a unit.
The inducer of the lac operon is allolactose. When lactose is present, a small amount of this molecule is converted to allolactose.
The lac repressor, which is encoded by the lacI gene, binds to the operator upstream of the lac operon, thereby preventing its transcription unless the inducer is present.
Finally, the lacZ gene produces an enzyme called β-galactosidase, while X-gal is a blue-colored product precipitated when a bacterial colony expresses a functional β-galactosidase.

Answer:
The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. ... Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration
