Basic Meiosis. An important part of gamete production is meiosis. In this process, diploid cells get the karate chop to turn them into haploid cells. Although sperm and egg production differ in many ways, meiosis is critical to both processes.
night blindness-vitamin A deficiency
color blindness - trouble distinguishing colors
hyperopia-eyeball too short
myopia-eyeball too long
astigmatism-light refracted aspherically.
<h3><u>Explanation:</u></h3>
Night blindness is defined as the disease which involves the mal production of retinol in the rod cells of retina. This leads to the decreased sensitivity of eye to dim light.
Similarly, colour blindness is a genetic disease which is characterised by absence of a particular pigment in cone cells. This restricts the vision of a particular colour.
Hyperopia or hypermetropia is the shortening of eyeball which leads to the focusing of light rays behind the retina. So convex lenses are required to focus them on retina.
Myopia is the opposite of hypermetropia where the eyeball is elongated and the light rays doesn't reach the retina. So concave lens are required to focus the rays on retina.
Astigmatism is the case where the curvature of lens isn't correct, and the lens required for the correction is cylindrical lens
B, when humans exhale we put out carbon dioxide.
Answer:
Transcription is DNA -> RNA
Explanation:
Transcription is DNA to RNA
Translation is RNA-> Proteins
Purple is dominant to white flowered.
Purple gene(which occurs in pairs of PP which are both dominant alleles) crossed with a recessive pp(white flowered) after crossing, all the offspring had Pp. Purple being dominant suppressed the white(p).
after crossing the offspring, (Pp and Pp) a quarter the offspring lacked the dominant allele P hence allowing the recessive colour white to be shown.
