Answer:
a.) rate of population growth
Explanation:
The population growth rate determines how a population will be distributed in a region. Populations with a high growth rate need to occupy more spaces, in addition to needing to consume a greater volume of natural resources. As the population grows, the distribution in the region becomes more intense, the opposite also happens. When the population growth rate indicates that the population is decreasing it means that this population will need less space and therefore, its geographic distribution will be smaller, as well as its impact on the region.

Ribosomes read information in a DNA molecule and use it to synthesize protein
Answer:
Explanation:
Why does your heart have to pump your blood to your lungs BEFORE it can pump it to the rest of the body?
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
what is responsible for pumping blood to the lungs?
The oxygen-poor blood fills the right atrium and then flows to the right ventricle, where it is pumped to the lungs through the pulmonary arteries. The lungs refresh the blood with a new supply of oxygen, which comes from the air that you breathe in.
The structure that are subunits of ribosomes manufactured in the nucleolus, inside the nucleus.
In eukaryotes the ribosomes are produced and assembled in the nucleolus. Here, the ribosomal proteins enters the nucleolus and combines with new four ribosomal RNA strand and create the two ribosomal subunit one is larger subunit 60s and another is smaller subunit 40s.
Then the ribosomes are connected by the 12 molecular bridges and both unit overlap to form 80s ribosome. The assembly of the ribosomes also took place in the nucleolus. Now the ribosomes undergoes the translation, formation of proteins.
