Answer: $\dfrac34$ dominants and $\dfrac14$ recessive.

Explanation:

Mendel's monohybrid cross is definied as

a genetic combination of two homogeneous genotypes.
One is dominant(TT) to other (tt-recessive).

Result in F1 generation: 4 dominant(Tt), 0 recessive (tt)

Result in F2 generation: 3 dominant(TT, 2Tt), 1 recessive (tt)

[If one T is present then we call it Tall (Donimant effect), if none then we call it dwarf]

The results in the F2 generation after a monohybrid cross: $\dfrac34$ dominants and $\dfrac14$ recessive.

____ happens when a lineage splits into two or more lines of descent.

Evgesh-ka [11]

When a lineage splits into multiple line of descents, then, it leads to speciation. It is a process by which a single population evolves into different species. The process of speciation leads to the development of two or more species as the lineages are splitted. These two evolved species are genetically independent.

Hence, the blank can be filled with 'speciation'.

Generalizations, explanations of natural phenomena, and additional hypotheses most often come about as a result of

natali 33 [55]

The explanations of natural phenomena, and additional hypothesis most often come about as a result of a scientific theory.

Explanation:

Scientific theory is a general explanation of natural phenomena developed through extensive and reproducible observations, more general and reliable than a hypothesis.

Then Every scientific theory starts as a hypothesis. A scientific hypothesis is a solution for an unexplained occurrence that does not fit into a currently accepted scientific theory. It must be based on careful rational examination of the facts.

9. Which structure helps animal cells maintain their shape?

ludmilkaskok [199]

Answer:

D. Cytoskeleton

Explanation:

It is really none of these answers. The correct answer would be a microtubule which is a component of the cytoskeleton which is in the cytoplasm.

The Cell Walls are only in plant cells so that won't work. So, A wouldn't work.

Chromosomes are the things that both your parents give you as genes. They have nothing to do with keeping the structure of the cell alright.

Cytoplasm cannot be a answer choice because, the thing is in it but, it doesn't do anything with it. So C wouldn't work either

The correct answer is microtubule however, it is a component of cytoskeleton so therefore, that is your answer.
