During metaphase 1 of meiosis of the cell cycle chromosomal translocation occur.
Explanation:
Chromosomal translocation is abnormal phenomenon when a fragment of chromosomes detaches and gets stick to the non-homologous chromosome in an individual. These are causative of aneuploid, cancer and infertility in organism.
In metaphase 1 of meiosis the chromosomes gets aligned on the metaphase plate. This leads to surety of equal number of chromosome in the cell.
Chromosomal translocation are seen in metaphase 1 because it is the phase of rearrangement of chromosomes where fragments easily gets attach to the other chromosome.
3. any trait that confers even a small increase in the probability that its possessor will survive and reproduce will be strongly favored and will spread through the population.
Explanation:
- Natural selection is a nonrandom process by which biological traits become more or less common in a population as a function of the differential reproduction of their bearers of differences in the rate of survival.
- Natural selection can act on any heritable phenotypic trait and operate among any entities that reproduce, show inheritance of their characteristics from one generation to the next, and vary in fitness.
- Natural selection is the machine that drives evolution. It also explains adaptation.
There are actually two planets referred to as gas giants which are Jupiter and Saturn. These two planets are made of mostly helium and hydrogen which makes them gas giants, while Uranus and Neptune have more ice and rock substances, so they are not considered gas giants.
Answer:
The iodine might have got into the bag by the process of diffusion/osmosis.
<em>In the process of diffusion, particles move from an area of higher concentration to an area of lower concentration along a concentration gradient. </em>
As we know, the iodine solution in the large container had more particles of iodine whereas the baggie had none of the iodine solution. As a result, a concentration gradient developed due to which iodine solution moved into the baggie through the process of diffusion or osmosis.
Answer: Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however. Some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.
