Write the formula that shows the release of energy by a molecule of ATP

Answer:

Based on the provided data, the six goldfish are placed in aquariums of varying sizes to assess how living space impacts their survival rates. The food type and quantity, sanitary conditions, and water temperature are kept consistent across the board.

Consequently, from this information, one can conclude that:

A. The independent variable is the aquarium size.

B. The number of fish remaining after six months represents the dependent variable.

C. Water temperature, food type and quantity, upkeep, and cleanliness are the controlled variables or constants.

Controlled experiments include both dependent and independent variables. The independent variable is usually the one that is altered and compared against a stable control. Meanwhile, the dependent variable, which is measured in the experiment, relies on the independent variable. The control group in an experiment is kept constant and is used for comparison with the experimental group.

Answer:

(A) 0.0625

(B) 25%

Explanation:

A

With the following:

T indicates tall

t indicates short

R indicates red

r indicates tan.

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

Let's analyze separately;

A short tan male goat = ttrr

The female goat’s genotype is not specified but it is known to be tall and red

∴ We determine that she must be T_ R_;

the potential genotype probability of the female for each allele could be:

- T

or Tt- RR

r

Nonetheless, from earlier discussion;

the chance that the female is Tt =

the probability of the female being Rr =

the probability of passing on the recessive allele 't' to offspring =

the probability of passing on the recessive allele 'r' to offspring =

∴ the likelihood that the pairing would yield short, tan offspring (ttrr) stands at;

=

=

= 0.0625

(B)

In pea plants, one is homozygous recessive for both traits, leading to the cross of Yy Rr × yy rr. Determine the green and round offspring percentage.

For Color, let:

Y = Yellow

y = Green

For shape, let;

R = Round

r = wrinkled

If a cross occurs between Yy Rr × yy rr. (yellow round and green wrinkled)

the ratio of green and round offspring will be;

If Yy Rr self-crosses; various traits (YR, Yr, yR, yr)

                   YR                    Yr                    yR                    yr

yr                 YyRr                 Yyrr                 yyRr                 Yyrr

yr                 YyRr                 Yyrr                 yyRr                 Yyrr

                   Yellow              Yellow            Green              Green

                   Round               Wrinkled        Round              Wrinkled

                   Thus, the percentage of green and round offspring based on the above is:

=
