Answer:

if the sun was farther away from Earth

Explanation:

by using the Formula of Universal Law of gravitational F = GM1M2/R² we can deduce the relationship of those symbols

for option 1

when the size increases , the mass also increases. Then the gravitational force increases

for option 2

when the size of Earth increase, the mass increase and thus the gravitational increases.

for option 3

when the distance between sun and Earth increases. The Gravitational Force decrease because F is inversely proportional with R²

for option 4

if the distance between Earth and the sun decrease, the gravitational force increases. then option 4 is wrong

the option 3 is the correct one .

What is the expected phenotypic ratio for feather colour if two chickens with blue feathers are crossed
ss7ja [257]

Answer:

The correct answer is - 1:2:1 for black : blue : white chicken.

Write the formula that shows the release of energy by the mitochondria
Pie

Answer:

Mitochondria is the organelle where cellular respiration takes place. Cellular respiration can be described as a process in which oxygen and glucose are converted into carbon dioxide and water along with the release of ATP. This reaction can be written as:

Glucose + Oxygen → Carbon dioxide + Water + ATP molecules

C6H12O6 +   6O2→  6CO2 +  6H2O +  ATP

The ATP made can be broken down so that energy is released.

ATP + H2O → ADP + Pi + free energy
