<span>The process of speciation is the
separation of a specific population into different species. The factors that
may affect to maintain this genetic isolation are: allopatric, sympatric,
prezygotic and postzygotic barriers. Allopatric barriers occurs when two
species that are of the same family before cannot go back to the way they were
before unless a contact between the two is established again. Sympatric are a
group of species that shared the same family before but forced to evolve
separately due to environmental factors. Prezygotic barriers are a group of species
that are formed from the developing fertilized egg. </span>
Answer:
a plant scientist who is modifying the genetic information of crop plants in a laboratory
Explanation:
just took the quiz on edg it was correct
Answer:
Apart from AB-type, other genotypes that would be formed will be A- blood type, B- blood type and O-blood type (the probability for each genotype is one-quarter )
Explanation:
As the parents are heterozygous in blood type, the gametes formed will be of IA, IB and i types, and thus the formed genotypes A- blood type, B- blood type and O-blood type will have same probability as that of AB-type.
These cells grow, and then divide to form a total of four cells. Those four cells grow and divide to form eight cells, etc. B) In meiosis, a single cell divides twice, resulting in four daughter cells that do not grow and divide again. Instead, these cells are modified to become eggs or sperm in humans
The correct option is this: MARINE BIOLOGY IS THE STUDY OF ALL ORGANISMS FOUND IN THE OCEAN, WHILE OCEANOGRAPHY IS THE STUDY OF THE PHYSICAL, CHEMICAL AND GEOLOGICAL FEATURES OF THE OCEAN.
Marine biology is the scientific study of all the organisms in the sea while oceanography is the study of the physical, geological and the biological aspects of the ocean.
