1 answer:

7 0

One way in which experimental research differs from observational research is that only experimental research can show cause and effect and is denoted as option D.

<h3>What is Cause and effect?</h3>

This is the situation in which one event contributed to the formation of another according to the type of relationship between the variables.

This is commonly used in experimental research so as to prove the interconnection and is tested by scientists in other to ascertain its authenticity.

A black chicken and a white chicken are crossed. What is the probability that they will have erminette chicks?

VashaNatasha [74]

Answer:

$Probability = 100\%$

Explanation:

Given

Crossing of a black chicken and a white chicken

Required

The probability of having erminette chicks

The genotype of a black chicken is represented as: BB

The genotype of a white chicken is represented as: WW

The genotype of an erminette chicken is represented as: BW

Using a Punnett square, we have:

$\begin{array}{ccc}{} & {B} & {B} & {W} & {BW} & {BW} & {W} & {BW} & {BW}\ \end{array}$

The result of crossing the two chicken gives 4 BW out of a total of 4

i.e 4 erminette chickens out of 4 possible chickens

So, the probability is:

$Probability = \frac{4}{4}$

$Probability = 1$

Represent as percentage:

$Probability = 100\%$

Identify the molecule that allows "complex chemical reactions to occur"?

Crossing over at prophase I results in the linked genes (those on the same chromosome) becoming unlinked and separated. Prophase I is this first stage of meiosis, the chromosomes condense, form tetrads, and exchange DNA. The nucleolus and nuclear envelope disappear.
