Answer:
1.) The two gametes found in humans are the sperm and the ova.
2.) Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).
3.) Because the alleles that the mother and the father carry are mixed together in the offspring.
4.) Because it only introduces genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.

Answer:
The observed image will not be sharp
Explanation:
When 100x microscope objective lens is being used, light refraction in the air is enough high to produce image alterations. Image distortions can be minimized by immersion oil because this liquid has a higher refractive index than air. However, light refraction is not usually noticeable when using 4x, 10x and 40x objective lenses. Moreover, this image will not be sharp after putting oil on the slide and going back to the 40x objective, it is for that reason that the 40x is called 'high dry' lens. In consequence, it is required to clean the immersion oil off the 40x objective. In general, it is required to to remove the oil and refocus off the slide and lens immediately after oil immersion (it can be done by using an oil-soluble solvent).

How do pseudopods work?The Function of Pseudopods. Pseudopods are actually extensions of the cytoplasm, or the thick liquid that is inside organisms like amoeba. The organism can change the shape of the pseudopod, making it move, appear, and disappear. The pseudopods are used in movement and as a tool to capture prey.
