Answer: Option B; correlation

Explanation: Cessation means a study made in controlled manner to evaluate the result of a condition which is terminated. Hypothesis in an experiment is a statement proposed at the beginning of the experiment, which is to be proved right or wrong. Causation is described as a situation where one event cause other even to happen.

When two variables are related, we use the term "Correlation".

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Below are the choices:

homogenous mixture
heterogeneous mixture 
semi mixture

You want to decorate the bottom of an aquarium with brightly colored rocks of different shapes and sizes. this describes a homogenous mixture

The word hetero means different. Since the rocks are varied i assume it would be a heterogeneous mixture.

How could the aquifer around the Los Angeles are in California be susceptible to an impact by a Tragedy of the Commons?

GuDViN [60]

Answer:

Due to over-pumping of water.

Explanation:

The aquifer around the Los Angeles are in California could be susceptible to an impact by a Tragedy of the Commons because the people used more water than the aquifer receives. The excess use of water from the aquifer through the well causes depletion of water which results in the shortage of water to fulfill the needs of existing population so it is wise to use water efficiently and used lower or equal water the aquifer receives in order to maintain level of aquifer.

Imagine that two unlinked autosomal genes with simple dominance code in goats for size, where T is tall and t is short, and for

Fittoniya [83]

Answer:

(A) 0.0625

(B) 25%

Explanation:

Given that ;

T is tall

t is short

R is red

r is tan.

If a short, tan male goat mates with a tall, red female goat of an unknown genotype;

Let's take it one after the other;

A short tan male goat = ttrr

The female goat is an unknown genotype, we will have to determine that but we were told that it is tall and red

∴ For tall it is T and red is R;

Definitely, the female genotype should be T_ R_;

the probability genotype of the female for each allele is either:

- TT or Tt

- RR or Rr

However, from above;

the probability that the female will be Tt = $\frac{1}{2}$

the probability that the female will be Rr = $\frac{1}{2}$

the probability that the recessive allele 't' will be transferred to the offspring = $\frac{1}{2}$

the probability that the recessive allele 'r' will be transferred to the offspring = $\frac{1}{2}$

∴ the probability that they would produce short, tan offspring (ttrr) will be;

= $(\frac{1}{2})^{4}$

= $(\frac{1}{16})$

= 0.0625

(B)

One of a pea plants is homozygous recessive for both genes, resulting in the cross Yy Rr × yy rr. Calculate the percentage of green and round offspring.

For Color, Let;

Y = Yellow

y = Green

For shape, Let;

R = Round

r = wrinkled

If a cross occur between Yy Rr × yy rr. (i.e yellowround and green wrinkled)

the percentage of green and round offspring will be;

If Yy Rr self crossed; we have the following traits (YR, Yr, yR, yr)

yy rr will result to (yr, yr)

YR Yr yR yr

yr YyRr Yyrr yyRr Yyrr

Yellow Yellow Green Green

Round Wrinkled Round Wrinkled

Therefore, the percentage of Green and Round offsprings from above is:

= $\frac{2}{8}*100%$ %

= $\frac{1}{4}*100$ %

= 25%
