The ozone layer absorbs most of the Sun's ultraviolet (UV) radiation. It contains high concentrations ofozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere and the inner core inner core is the Earth's innermost part and according to seismological studies, it has been believed to be primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 70% of the Moon's radius. It is composed of an iron–nickel alloy and some light elements.
The answer to this question would be: half of
Gametes cell is a haploid cell that only has half of genetic material from the parent cells. The process of making gamete cells is called meiosis.
The gamete is haploid because it was used in fertilization and need to fuse with other gametes(example: sperm with the egg) resulting in a full paired chromosomes.
The correct answer is - A and B.
The nuclear energy can been seen at either way, and that is why it has both its supporters and its critics.
The nuclear energy is cheaper, cleaner, and nuclear centrals can produce much more and much more efficiently as well, so it can easily be seen why it can be extremely useful in a world where the energy demand is ever-growing.
On the other side, there's a huge risk with the nuclear centrals because if there's some problem, it can all turn into a catastrophe that will affect huge area. The consequences of a nuclear reactor exploding or leaking are long term, and takes lot of time that the area can be used for anything. Lots of human lives can be lost, and affected for numerous generations, as well as destroying the natural environment in a brutal way.
Answer:
The correct answer will be- Meiosis I, anaphase I
Explanation:
Alleles are the variant alternative forms of a gene which determines the trait of an organism. The trait or phenotype is expressed only when the two alleles controlling a single trait on separate chromosomes are aligned in a complementary position.
During gamete formation, the alleles controlling a trait segregate independently of each other. This segregation of alleles takes place during Anaphase I of meiosis I. During anaphase, the sister chromatids are separated by the mitotic spindles so that the chromosomes can reach the opposite poles.
Thus, Meiosis I, anaphase I am the correct answer.
