Answer:
There is some debate about the definition of a species, especially across fields. However, what it likely being discussed here is the biological species concept which states that:
An organism is considered a new species when there is reproductive isolation from the population that they originated from. In other words, for two organisms to be the same species they must be able to reproduce to create viable (able to survive) and fertile (able to reproduce) offspring.
Reproductive isolation can occur by different means, classified as being prezygotic or postzygotic isolation. These include things like mechanical, behavioral, temporal, ecological, and geographical isolation for prezygotic isolation. And things like hybrid infertility and hybrid inviability for postzygotic isolation. These are not relevant to the question but they give you an idea of what you could look up if you wanted more information.

Answer:
F=dominant, 6 fingers
f= reccessive, 5 fingers
Ff= 6 fingers( contains dominant gene)
if you combine Ff and Ff you get:
25% FF (6 fingers)
50% Ff (6 fingers)
25% ff ((5 fingers)
so only 25% will have 5 fingers (normal)
Answer2:
Dominant=normal hearing
Recessive= deafness
If one parent is RR and the other Rr, the offspring will be:
50% RR
50% Rr
so all the offspring will have normal hearing, and there is 0% of deafness.

Answer:
Parenchyma cells are the abundant cells that make up ground tissues in plants.They are flat at point of contact.they have thin primary cell walls and have large vacuoles for storage of food.In leaves they are called mesophyll and are sites of photosynthesis.In other parts they are sites for respiration and protein synthesis.
Sclerenchyma cells are cells with rigid secondary cell walls.Their cell walls are hardened with lignin which is the main chemical component of wood.Mature sclerenchyma cells cannot elongate and most of them are dead.
