Telophase 2 is the final step of meiosis 2 in which homologous chromosomes reach the opposite poles and four haploid cells are formed.
Explanation:
The telophase 2 ends up in four haploid (n=2) cells. It is in this phase the genetic material of the parent cell is divided into 2 daughter cells. The events taking place are nuclear membrane reappears (karyokinesis has taken place by now), spindle fibres and astral rays disappear, chromosomes decondensed to become chromatids (thin fibres), constriction on equatorial plate consequently four daughter cells formed.
Answer:
The bell of the stethoscope is used during auscultation to listen for low pitched sounds typical of a heart murmur.

it is actually forests so a
Answer:
Air is a matter
Explanation:
Matter is anything that has mass and takes up space. So, in order to prove that air is matter, we need to prove that air has mass and takes up space. It's easier to prove that air takes up space, so let's do that part of the problem first.
Get a balloon and inflate the balloon with air. The balloon get larger as you put air into them. The only way that air could make them get larger is if air takes up space.
Also the balloon can be weight before air is added and after addition of the air. The weight will be much after adding air
