Answer: As scientists started improving on the microscopes, the more they got to observe the cells in depth. Compound light microscope uses visible light to produce a magnified image and doesn't allow it to scatter.
Flatworm get most of their oxygen through diffusion.

Explanation:
Antibiotics, Antiparasitic, Antifungal
The answer is c. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
Meiosis is a cell division which results in the reduction of chromosome number by half (from diploid to haploid) in daughter cells. It consists of meiosis I and meiosis II.
In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicates which are present as pairs of sister chromatids. When comes to separation, homologous chromosomes separates only, but not sister chromatids. Homologous chromosomes are present only in meiosis I.
In anaphase II, since the cell is haploid, there are 23 chromosomes in duplicates, which are present as sister chromatids. So, in this phase, sister chromatids are those who separates.
To easy remember it,
Phloem, has the (f) sound, so it carries food and nutrition like sugars all around the plant, up and down movwment.
while Xylem carries water and minerals, from down the soil up to the plant, only up movement.
