The question is incomplete. The complete question is as follows:
planet a: mass 3,500 kg
planet b: mass 50,000 kg
planet c: mass 750 kg
planet d: mass 100,000 kg
a)planet a
b) planet b
c) planet c
d) planet d
Answer:
Planet d.
Explanation:
The universe consists of the sun, planets, galaxies and stars with all other dust particles. Mercury is the closest planet to the sun. Earth is the only planet that supports the life.
The force of gravity can be calculated by the formula,
F =
From the formula it is clear that the mass of the planet is directly proportional to the force of gravity.
Here, the distance is same. So the planet with the largest mass has highest force of gravity. Among the given options planet (d) will experience the strongest force of gravity.
Thus, the correct answer is option (d).
Answer:
The PH at which an enzyme will function best is;
In the optimal range
Explanation:
Every enzyme has an optimal pH value which is specific for the enzyme, and where their maximum activity of the enzyme is observed, which is known as its optimal pH
When the enzyme is placed in a different pH, the enzyme activity is observed to be diminishing until the effect of the enzyme stops
This is so because, as the pH of the environment changes, the shape of the active site on the substrate to which the enzyme binds to have an effect changes and the enzyme is no longer able to effectively interact with the substrate
The enzymes in the stomach work best in the acidic environment of the stomach and have an optimal pH of 2, while the enzymes of the small intestine have an optimal pH of 7.5
Answer:
c. the presence of nucleic acids
i hope that this is the answer imma say choice b
Cancer is a genetic disease—that is, cancer is caused by certain changes to genes that control the way our cells function, especially how they grow and divide. Genes carry the instructions to make proteins, which do much of the work in our cells.
