Answer:
Twins, says Dr. Judith G. ... Fraternal twins are known to arise when two eggs are released from the ovaries, get fertilized and implant together in the womb. In contrast, identical twins start out as a single embryo, split, and then develop as separate individuals in the womb.
Nuclear power refers to the application of nuclear reactions, which discharge nuclear energy to produce heat and is most generally utilized in steam turbines to generate electricity in a nuclear power plant. Nuclear energy can be obtained from nuclear decay, nuclear fission, and nuclear fusion reactions.
The controlled release of nuclear energy in a reactor is attained by controlling the fission without controlling a chain reaction. If a chain reaction occurs, then the amount of energy would increase exponentially, so in order to monitor the release of energy, fission must be controlled without controlling a chain reaction.
The oldest type of bacteria is over 3 million years old I think. It comes from the cyanobacteria family! The bacteria is a type of algae! Discovered by Gregorio V. in the Late 1900's.
Answer:
Explanation: Without gene duplication, mutation of genes would not exist. This would prevent organisms from adapting to their environment, making survival much more difficult if not impossible.
<span>Meiosis consists of one round of DNA replication accompanied by two rounds of cell division.
Before meiosis starts, the cell </span><span>goes through an interphase period in which it grows, replicates its chromosomes to have enough material to divide for the daughter cells.
Unlike mitosis, meiosis has 2 cell division (meiosis
I and II). At the end of the first division, </span><span>each cell has half the number of chromosomes of the parent cell. At the end of the second division</span> there is separation of the sister chromatids
