Answer:
C, the specimen will appear fuzzy and have poor resolution
Explanation:
Immersion oil is used in a microscope to improve image quality. The oil has a high refractive index that allows light concentrate on the specimen (prevent light from away from the specimen).
Choice two and five are correct!
WHAT IS THE MAJOR EVOLUTIONARY ADVANTAGE TO PRODUCING AN AMNION?
The main evolutionary advantage of producing an amnion is that the embryos of the amniotic membrane,the amniotes are made available with their own aquatic environment,this in-turn resulted to a lesser dependence on water for it's maturation and development therefore allowing or giving room for the amniotes to branch towards environments that are drier.
WHAT FOES THAT MEAN GOR EMBRYONIC DEVELOPMENT OF THE ANIMAL PHYLUM AS COMPARED TO THE ANIMAL PHYLA?
The embryonic development of animal phylum is also known as embryogenesis.
It is the development of the embryo from the point of fertilization of an egg,(the ovum) by a sperm cell ,this makes the fertilized egg a diploid cell otherwise known as a zygote.
This zygote undergoes mitosis,a mitotic division known as cleavage and a differentiation resulting in a multicellular embryo.
This embryonic development of animal phylum comprises of 36 animal phyla.
A.
The independent variable (experimental variable) is the exposure to UV lights of the tadpoles because it is being varied. The dependent variable is the survival of the tadpoles, because it is the one being affected by the independent variable.
B.
The information from the experiment does not support the hypothesis because an equal number of tadpoles remain, while the hypothesis predicted that less would remain in the tank exposed to UV light.
C.
Other factors such as temperature of the water may be affecting the frog populations.
D.
The control group was the tank covered with glass and the experimental group was the tank covered with acrylic plexiglass
E.
The difference was that one group was exposed to the UV light, while the other group was not. No, they should not be different in any other way, because that may lead to inconclusive experimental results.
Both mitochondria and ribosome are so tiny structure, it can not be seen under light microscope. It needs more magnification to study the detail structure, hence electron microscope is best to use.
<h3>What is ribosome ?</h3>
Ribosomes are small membrane less organelles and are the sites of protein synthesis.
It is present in are found in both eukaryotic and prokaryotic cells.
Ribosomes can either be present alone or in groups in cytoplasm while some ribosomes are attached to the endoplasmic reticulum called as rough endoplasmic reticulum.
These are composed of ribosomal protein and RNA, have two subunit larger and smaller subunit.
