Answer:

-Prophase.

Explanation:

Cell cycle involves a series of events that leads to formation of two daughter cells by division of a parent cell. It can be divided into two phases, interphase and mitotic phase (M phase)

The M phase involves division of nucleus and cytoplasm to produce two daughter cells. It is divided into prophase, metaphase, anaphase, telophase and cytokinesis.

Hence, the first stage of M phase is prophase, in which condensation of chromosomes begins, nuclear membrane disintegrates, and nucleolus starts to disappear.

Thus, the correct word to be fill in the blank is 'prophase

Answer:

Answer for question 2:

It is important to receive data from three separate locations because the more we know about the seismic waves and the places that they are more we gain for learning about them.

In certain mice, long tails (T) are dominant over short tails (t). If 2 hybrid mice mate, what will the outcome be?

yuradex [85]

Answer:

3 long tails : 1 short tail

Explanation:

This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length.

According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:

Tt - T and t

Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.

Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.
