I believe the answer would be A.
The flow is larynx, trachea, bronchi, bronchioles, alveoli
Answer:
a. Genotype of male parent= BbNn
Genotype of female parent: bbnn
b: Progeny ratio= 1: 1: 1: 1
c: 1/4
Explanation:
a. Genotype of male parent= BbNn
Genotype of female parent: bbnn
b. Gamete formed by the male parent: BN: Bn: bN: bn in 1:1:1:1 ratio.
Gametes formed by female parent: All gametes with "bn" alleles.
c. The probability that the offspring will have a genotype of Bbnn=
Bb x bb= 1/2 Bb: 1/2 bb
Nn x nn= 1/2 Nn: 1/2 nn
Therefore, probability that the offspring will have a genotype of Bbnn= 1/2 Bb x 1/2 nn= 1/2.
Answer:
Chloroplast and mitochondria
Explanation:
Chloroplasts are organelles present only in plant cells and algae in regions that become illuminated. They are green in color due to the presence of chlorophyll and are responsible for photosynthesis. Chloroplasts produce ATP in the presence of sunlight and therefore the heaviest fractions should contain these organelles.
Mitochondria are cellular organelles related to the process of cellular respiration. They are often referred to as “powerhouses” of cells because, through the cellular respiration process, a large amount of ATP is generated. Mitochondria do not need light to produce ATP, so it is likely that these organelles are present in the lightest fractions.

</span>A. Roche Moutonnees
Explanation:
Rôche moutonnée (or sheepback) could be a rock formation created by the passing of an ice mass. The passage of ice mass ice underlying bedrock usually leads to uneven erosional forms as a result of abrasion on the "stoss" (upstream) facet<span> of the rock and plucking on the "lee".

This mutation type is a substitution mutation. Substitution mutations may be silent or may have adverse effects (missense mutation).
Adverse effects come about because the change in codons in mRNA transcribed from the DNA strand. A point substitution can change the amino acid being coded for in the particular polypeptide change. If that animo acid is a structural residue of the protein, the structure of the protein will be altered, which may or may not lead to a change in protein function. If that particular amino acid is a catalytic residue of the protein, it may alter the 3D conformation and charge of the active site (if protein is an enzyme) or the binding site of protein. Function of protein formed from mutated DNA will be lost or altered.
Hope this helps! :)
