A light microscope uses focused light and lenses to magnify an object. Light microscopes come in several forms. (1) Simple light microscopes use a single lens to magnify an object and cannot reach high magnification just like a handheld lens whose highest clear magnification in the best conditions is 25x. (2) Compound light microscopes use two sets of lenses - an objective lens and an eye piece. This is the type of light microscope whose magnification power reaches between 1000x and 2000x.

Explain how the independent alignment of homologs, and also crossing-over during the first meiotic division, each contribute to

BartSMP [9]

Answer: Homologous chromosomes are randomly distributed to daughter cells, this means different chromosomes segregate independently of each other. And they exchange segments of DNA during crossing over. This recombination creates genetic diversity because genes from each parent are exchanged.

Explanation:

Meiosis is a type of cell division that produces gamete cells, which are sex cells (egg and sperm)

Chromosomes that form a pair and are found together are called homologous chromosomes, and they are inherited from each parent. During prophase of meiosis I, the homologous chromosomes exchange segments of DNA in a process called crossing over. This recombination creates genetic diversity because genes from each parent are exchanged. It results in new combinations of genes on each chromosome.

After that, during the anaphase of meiosis I, the two chromosomes line up on the equatorial plane of the cell. Then, they are separated and each will go to a new daughter cell. So homologous chromosomes are randomly distributed to daughter cells, this means different chromosomes segregate independently of each other.

When resources are limited, explain 4 ways by which lizard species on the Bahamas Island can coexist

aliina [53]

Answer:

Explanation:

Coexistence occur when individual occupying in a particular place are able survive with limited resources.

Dispersal - some of the lizard go hunting, they disperse themselves to various places to get resources.

Stability mechanism- this happen when individual stabilizes them selves in a particular habitat dealing with

environmental variations that may occur and drift them apart.

Equalizing mechanism - they all try to be at the same pace to avoid been out compete, even though some are stronger they equalize their energy for all to manage the limited resources.
