Under the dissecting microscope I was able to view the surfaces of specimens such as a feather, insect, and leaf.
Under the compound microscope I was able to view a leaf, blood, and algae. I was able to observe the surface of the specimens in greater detail then I was able to view the surfaces under the dissecting microscope. For an example under the compound light microscope I was able to view the leaves surface which contained multiple lines that intertwined into each other and rectangular chambers of green dots. But under the dissecting microscope I was only able to view the surface of the leaf which consisted of thin white cracks in the leaf.
Under the scanning electron I was able to view the internal structure of the following specimens: a leaf, blood, and algae.
Under the transmission electron I was able to view a more in depth internal structure of the following specimens:a leaf, blood, and algae. I was able to observe the intern
al structures of the specimens in greater detail then I was able to view the internal structures under the scanning microscope. For an example under the TEM I was able to study the internal structure of a leaf which consisted of long thick and thin black and gray lines coated with black rectangles and tiny dots littering he perimeter of what looks to be the internal structure of the leaf. But with the SEM I was only able to view the first layer of the leaf's internal structure which consisted of mushroom like figures surrounded be compound and single molecules.
Answer is A.. hope this helps:)
Answer:
stratum corneum
Explanation:
Keratin is a structural protein that builds up hair, skin and nails.
The stratum corneum is the outer most layer of the epidermis that contains Keratinized cells. It serves as the primary protective barrier. Its thickness varies throughout the body .
The hair shaft is the part of the hair seen above the skin. Just like the stratum corneum , it is also made up of the protein keratin compacted and fused together.
Answer:
Plasma.
Explanation:
Plasma is the liquid component or constituent of the blood after the removal of all the cells and platelets. It is composed of 90% water, coagulation factors like antibodies, electrolytes, proteins , lipids e.t.c which help to maintain the blood PH and osmotic balance of the blood during the process of giving viscosity to the blood. The plasma comprises of 55% of the blood.
