Answer: To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
Answer:
b. phospholipid bilayer of membrane
Explanation:
The phospholipid bilayer evidently has in its structure mainly phospholipids, alcohol compounds and fatty acids.
Each molecule in the membrane phospholipid bilayer has two heads and a tail, both heads being hydrophilic (having affinity for water) and the tail being hydrophobic (having no affinity for water, and therefore repelling it).
This structure, with the heads, which are hydrophilic facing the intracellular and extracellular environments of cells, thus prevents the passage of polar compounds.
Answer:
The genotype of the parents are not given. Let's try to answer this question generally. Let's assume the genotype of both parents to be Bb as genotype is not given.
Explanation:
B b
B BB Bb
b Bb bb
There is a 25% chance that the offspring will have BB genotype.
There is a 50% chance that the offspring will have Bb genotype.
There is a 25% chance that the offspring will have bb genotype.
There is a 75% chance that the offspring will have a dominant trait.
There is a 25% chance that the offspring will have recessive trait.
Phenotypic ratio will be 3:1
