A. Extinction is a natural part of life on earth
I can just send a picture it’s way to confusing
Answer: Myelin
Explanation:
The speed of the neurotransmission increases as we grow. The behavior of the teenager is quite different from the behavior of the adolescents.
They are more active, heroic and wants to take risk. This is because their brains are not completely developed till they reach the age of 25.
As they grow and reach the late 20s the white mater in the brain increases as the frontal lobe is the last part of the brain development.
Due to the development of the myelin in the frontal lobe the transmission of the signal increases at adolescence.
The answer is <span>Fish are ectothermic and lay eggs to reproduce, while mammals are endothermic and give live birth to offspring.
Through the elimination process:
</span><span>* Fish are <u>invertebrates</u> and have scales and paired fins, while mammals are vertebrates and have fur or hair. - Fish are vertebrates!
</span><span>* Fish are <u>endothermic</u> and have gills, while mammals are <u>ectothermic</u> and have lungs. - Fish are ectothermic (cold-blooded), and mammals are endothermic (warm-blooded)!
</span>* <span>Fish have streamlined bodies and <u>three-chambered hearts</u>, while mammals are <u>bipedal</u> and have four-chambered hearts. - Fish have four chambered hearts and not all mammals are bipedal!
This leaves choice: </span><span>Fish are ectothermic and lay eggs to reproduce, while mammals are endothermic and give live birth to offspring. All of this is true, but it should be taken into consideration that some fish give live birth and some mammals lay eggs, but this is the most possible choice among all mentioned.</span>
Answer:
c. Acclimatization
Explanation:
Acclimatization is the process in which an individual adjusted itself in order to respond adequately to a change in its environmentm- in this case, the change from sea water to freshwater- and maintain good performance. Acclimatization occurs in a short period of time and <em>within the organism's </em><em>lifetime </em><em>. </em>This last part is an important difference between acclimatization and adaptation, becasue an adaptation is a change that has taken place over many generations.
