Transmitted, vertical
A transparent specimen is viewed through a microscope using transmitted light while an opaque object requires vertical illumination.
Transmitted light is the light that passes through an object. Transmitted light microscopy is any kind of microscopy in which the light is transmitted from a source located directly across the specimen from the objective. The light is commonly passed through a condenser in order to focus it on the specimen to obtain very high illumination. After the light passes through the specimen, the image of the specimen moves through the objective lens and later to the oculars where the enlarged image is viewed.
Answer:
Organism with AABBCCDD genotype will produce only one type of gamete, ABCD and the organism having the genotype AaBbCcDd will produce 16 types of gametes.
This is a percentage of 3.1%
Explanation:
It takes seven seconds for the pupil to adapt once again to dark conditions after getting exposed to headlight glare.
The pupil of the eye refers to the black circle at the midpoint of the iris. The pupil functions mainly to monitor the amount of light getting inside the eyes, to make sure that to much light does not blanch out the visions in extremely bright light conditions, and to capture as much light as possible in dim light conditions.
All mentioned complexes (receptor-hormone, antibody-antigen, enzyme-substate) are involved in a molecular recognition.The molecular recognition involves <span>non-covalent </span> interaction between molecules. To form complex, molecules must be complementary in shape and charges, and usually, they are compared to key and lock. This way, the selectivity and specificity of recognition between molecules are assured.
Answer:
<h2>
A
</h2>
Explanation:
1. A channel between two adjacent cells in known as an intercellular cleft.
2. And through these channels many molecules can easily pass between cells.
3. Importance of Intercellular clefts:
i) It is very important in transportation of fluids and small solutes.
ii) It contains gap junctions, tight junctions, desmosomes, and adheren proteins and these junctions help in regulate cell communication by signal transduction, surface receptors, or a chemogradient.
