They are a type of photoreceptor in the retina responsible for color vision. There are three types of cones; blue, green and red mainly packed in the fovea.  The other type of photoreceptor is the rods responsible for black and white vision and are mainly located in the peripherals of the retina.  Rods can perceive dim light, unlike cones.

Viefleur [7K]

Answer:

<em>The correct option is A. Nucleotide sequence, human, hemoglobin</em>

Answer:

Option B

Explanation:

ALL options are as follows -

a. teosinte and maize can produce fertile hybrids.

b. teosinte and maize have similar chromosomes.

c. Both Teosinte and maize have naked, soft kernel.

d. Teosinte and maize can produce fertile hybrids

Solution

Beadle started working on maize genetics since 1962 after joining graduate school at Cornell University.  

During his research he found that the chromosomes of teosinte and maize possess higher similarity and also show signs of intercross ability of the two species and hence confirmed that wild teosinte is an ancestor of domesticated maize.  

He later concluded that there are only 4 to 5 genes that make these two species different from each other rest all is similar.  

Option B is correct

Explain how the structure of epithelium and the structure of connective tissue, specifically bone, relate to the function of the
Aneli [31]
<span>Epithelial tissue is densely packed cells that used most in the area where protection is needed. This cells mostly used in skin, some with more keratin which will increase their ability to protect. In bone, the main protective layer is calcium mineral which was deposited by osteocytes. Because this bone doesn't really need more epithelial cells. Bone tissue only needs a good vascularization and connective tissue to support it.
