Answer:
We are only given one leaf, but the leaves in layer D of the same species would not be identical. Some of them could have deeper indentations or fewer indentations. A wider leaf surface area lets a plant absorb more sunlight, so it would be an advantage if leaves have fewer indentations.
The plants with fewer indentations will reproduce more, passing on their genes for fewer indentations. This repeats for a long time, then plant leaves overall would only have very small indentations (like the leaf for layer B).
Explanation:
There are mutations and variations that make one organism different from another organism, even if they're the same species.
Natural selection is when the environment "chooses" the organisms that have an advantage in the environment to reproduce. Organisms that are selected to reproduce can pass on their genes to future generations.
The deep indentation leaves from layer D were basically "phased out".
It would need to be in a place with lots of space because solar power requires two things: space and money. (It's also a clean energy source!)
Answer: Length, Shape and density of an object do not necessarily determine the shape of a crater
Explanation: a crater is a rough opening on a solid surface, it might be circular or any shape. The major factor that determines the shape of a crater is the mass and velocity of the impactor like the meteorite. When an impactor hits a solid surface, it breaks out in all director irrespective of the shape of the impactor. We have simple and complex craters depending on the impact strength.
Answer:
The correct answer would be the heterozygous condition in incomplete dominance type of inheritace.
Explanation:
Incomplete dominance is the point at which dominant allele, or type of a quality, doesn't totally veil or masks the impacts of a recessive allele, and the living being's subsequent physical appearance shows a mixing of the two alleles. It is additionally called semi-dominance. One model has appeared in roses.
In roses, if two true breeding plants crossses together they will produce heterozygous in F1 with the impact of the both dominant and recessive alleles.
To be clear MOST cells have identical dna(sex cells don’t have identical) but they do have identical cells because of what during the cell cycle(interphase-s phase) duplicates the dna
