Individuals with the recessive trait of night blindness (genotype nn) have difficulty seeing in low light. The pedigree shows the inheritance of night blindness in a certain family.Which of these are possible genotypes of the parental generation? Refer to the figure below and match the angle with the correct measurement in degrees.
Answers
Answer:
Cool
Explanation:
The possible genotypes of the parental generation are as follows :
Male : Night Blindness Female : Normal What is Genotype ?Genotype is the collection of the the two alleles that makes up the gene inherited by an offspring from its parents.
Given that only one of the males of the first generation suffers from Night blindness, He inherited the Night blindness from the parental generation. therefore the male from the parental generation is a carrier of the Night blindness allele while the Female is not a carrier.
Hence we can conclude that The possible genotypes of the parental generation are Male : Night Blindness and Female : Normal.

Answer:
the answer is a i hope this helps
Explanation:
The sac-like structure of the alveoli increases their surface area. In addition, the alveoli are made of thin-walled parenchymal cells. These features allow gases to easily diffuse across the cells. so the
Alveoli has thin walls which are surrounded by blood vessels, and they have maximized are for gas exchange. Thus, option A, B, and D are correct.
What are Alveoli?These are basic respiratory units, which are balloon like structure present in the lungs, where exchange of gases takes place. A pair of human lungs can contain approximately 480 million alveoli, which produces about, 50 to 75 square meters surface are.
Alveoli are made of thin walls, and they are covered by a rich blood supply through capillaries, this supplies a diffusion gradient for oxygen to move into the blood and carbon dioxide to move into the lungs.
Therefore, the larger surface area, presence of thin wall, which is only one cell thick, and rich blood supply due to presence of blood vessels enable them to exchange gases efficiently.

Sorry I really just needed the points ;(
Explanation:
Answer:
1) Amplitude of wave A: 0.5 meters
2) You would have to find the wavelength with the equation λ = [tex]\frac{v}{f}[/tex]
Explanation:
1) Amplitude of a wave is the height of the wave from the horizontal line drawn on "0" to the highest point on the wave.
2) λ is lambda, sign for the wavelength. V is the velocity of the wave, and F is the frequency of the wave.
