Answer:
Mitosis and meiosis are similar at the level of writing, and possess a very close mechanism; however, they do not achieve the same result!
Mitosis corresponds to a single "asexual" cell division of somatic cells (almost all cells in the body), and clones two daughter cells from a mother cell, which will be identical, and inherit exactly the same heritage genetic, indeed these two daughter cells will each have an identical karyotype (same chromosomes) and an identical genotype (same alleles) to that of the mother cell.
Meiosis corresponds to two successive "sexual" cell divisions affecting only germ cells; starting from a diploid cell (chromosomes present in pairs), meiosis leads to the formation of four gametes (haploid sexual cells, spermatozoa or oocytes) (a single copy of the chromosomes). Then, during fertilization, two gametes (each from meiosis, in the male and female) come together to form a zygote, in which diploidy will be restored.
The right answers are:
create two identical cells ==> mitosis
create four non-identical cells ==> meiosis
create haploid cells ==> meiosis
creates diploid cells ==> mitosis
occurs in all cels other tha gametes ==> mitosis
occurs in all cells related to sexual reproduction ==> meiosis

Explanation:
Answer:
A) heritable traits cannot be altered by experience
Explanation:
This is because the Darwinist believe that heritable traits were acquired from previous generation not from practise or learning which may develop to experience with time.He believed that certain selective pressures must have acted or selected these organisms to possess these heritable characteristics, and can not be altered by experience whicg is acquired with age.
He should conclude therefore that variation in the organisms which possess these characteristics should be the main factor which gives them selective advantages to inherit these traits compare to others in this same surrounding environment Therefore he will discard the influence of environment.
Cancer: An abnormal growth of cells which tend to proliferate in an uncontrolled way and, in some cases, to metastasize (spread). Cancer is not one disease. It is a group of more than 100 different and distinctive diseases. Cancer can involve any tissue of the body and have many different forms in each body area.
im pretty sure it is the first one
Answer:
I'm thinking the answer would be C if not then it would be B
Explanation:
Answer:
B) temporal summation
Explanation:
When two EPSPs occur at the same synapse, the process called temporal summation occurs.
Temporal summation is the process of combining the postsynaptic potentials of different neurons as they are added in sequence.
When occurring in rapid succession, the final potential becomes a cohesive sum of the postsynaptic potentials. Therefore, temporal summation can be defined as the sum that creates postsynaptic potentials at different times.
