The gene EEF1 ALPHA1 supports cell theory. Cell theory states that all living things are made from cells. Since all living things share this gene that dates back to an organism that lived billions of years ago, it makes sense to conclude that all living things originated from the earliest forms of life. This conclusion would explain why all living things on Earth are made of cells.
Answer:
Explanation:
The theory of uniformatrianism was proposed by James Hutton, a Scottish Geologist by profession.
This theory was a contrast proponent to the tenets of the theory of catastrophism in existence before then in the scientific circles
The theory states that "the present is the key to the past and geologic processes occurring today have happened in the times past".
- The theory correlates geologic processes as continuous in nature rather can punctuated situations.
- Erosion occurring today has been changing the land surface on earth as far back into the geologic times and periods.
- From the image, the erosional activities are still continuing today.

Explanation;
Cultural familial is a mental deficit in which no evidence of organic brain damage can be found; individuals' IQ range from 55 to 70. Psychologists suspects that these mental deficits often results from growing up in a below average intellectual environment.
The correct answers are evolution, genetic mutation and selection.
The early ancestors of horses showed the pressence of digits and now the modern horses have hooves in their limbs. There could be many reasons for the pressence of hooves horses.
These could be due to the genetic mutations, which could have changed the shape of the digits in the limb. Sudden change in DNA can cause mutation and this mutation can change the phenotype of the horse.
There are chances that evolution took place over a period of time that changed the character in the horse.
Natural selection can also be one of the reason for the change in the phenotype of the digits on the limb of the horses.
