Answer:
D. Active transport.
Explanation:
Active transport is the method that uses the ATP's energy to move ions and molecules from one side to the other of the membrane. The elements move from a place of lower concentration to one of a higher concentration. They move against their concentration gradient, which is why they need the energy to do it. There are two types of active transport, primary and secondary.
The primary active transport is ion pumps that hydrolyze ATP using one of the phosphates of the ATP to change the pump's shape and move the elements against their concentration gradient. It uses the ATP's energy directly.
The secondary active transport does not use ATP directly. It uses the electrochemical gradient that the primary transport had created when hydrolyzing ATP to transport the ions and molecules.
Answer:
Arginine
Explanation:
A specific genetic code specifies a particular amino acid. One amino acid can be encoded by more than one genetic code.
When a particular amino acid is encoded by more than one genetic code, all the genetic code for that amino acid mostly share common first two bases and differ from each other in the last base. This allows the same tRNA with particular anticodon to read all the possible genetic code for that amino acid and to serve as a carrier due to wobble base pairing.
Given that code "CGG" specifies arginine, the code "CGA" should also specify "arginine" since both differ with respect to the last base only.
Answer:
Physical trauma, acute disease, chronic disease, infectious disease and emotional trauma.
Explanation:
Physical trauma, acute disease, chronic disease, infectious disease and emotional trauma are the ways from which health should be affected by happening of natural disasters such as earthquake and cyclones. We are able to predict the weather with the help of satellites that monitors the movement of clouds on the earth atmosphere. Advancement of technology is the main reason which enable us to predict the weather conditions as well as the coming of cyclones in a specific region.
Answer:
Those organisms survive and maintain its population who are chosen by natural selection.
Explanation:
This statement means that when the population experiences a new set of environmental conditions, two things are happened i. e. the population either adjusts through natural selection or becomes extinct. The fossil of dinosaur indicates that extinction occur due to changed in the environment. If the population made changes in itself and adapt the environment then the organism survive otherwise extinction occur.
