Without the greenhouse effect, there would be more ice on Earth’s surface. The answer is B.
Question continuation;
..........type B. Type A is found to be more common in the mainland population from which the island was settled.
How could a geneticist best explain the dominance of blood type B in the island population?
Multiple choices;
A. Random mutations have occurred in the island population.
B. Genetic drift has reduced the frequency of type A individuals.
C. Natural selection has only occurred in the mainland population.
D. Environmental conditions on the island are less favorable for type B individuals.
Answer;
B. Genetic drift has reduced the frequency of type A individuals.
Explanation;
-Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance.
-It occurs in all populations of non-infinite size, but its effects are strongest in small populations.
Answer:
Both binary fission and mitosis produce genetically identical daughter cells.
Explanation:
The process in which new cells are made in order to grow, replenish (repair), and reproduce is called cell division . The three main types of cell division are binary fission, mitosis, and meiosis. In prokaryotes like bacteria cell division take place through binary fission, while eukaryotes (e.g., plant and animal cells) uses two types of cell division - mitosis (the process of making new body cells like blood, muscle etc ) and meiosis (reproductive cell division that creates egg and sperm cells).
Binary fission is a simple and rapid process in which a single parent cell divides to form two genetically identical daughter cells. The main function of binary fission is reproduction.
In mitosis, a cell is replicated into exact copies of itself and duplicates all of its contents including the chromosomes and splits to form two identical daughter cells. It is a complex process in which cells pass through different phases called cell cycle during cell division.
Meiosis is a type of cell division in which four haploid cells are produced from a diploid parent cell having two copies of each chromosome, where the number of chromosomes in the parent cell is reduced to half by undergoing DNA replication and nuclear division.
Both binary fission and mitosis are types of asexual reproduction in which the DNA is copied and the cytoplasm is divided (cytokinesis) to form two genetically identical daughter cells, which contain an exact copy of the parent cell's DNA.
Answer:
<u>B.It increases the surface area available for ATP production, which results in faster cell growth.</u>
Explanation:
The electron chain reaction in the mitochondria occur at the inner mitochondrial membrane, So greater the folding of inner membrane of mitochondria that is also known as cristea, greater would be ATP Production.
