Answer:
The crust cracking.
Explanation:
Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. ... The less-dense material rises, often forming a mountain or elevated area of the seafloor.
Fossil evidence suggests that the tiktaalik had lungs, which meant that it could breathe in air, instead of just water.
This trait allowed the tiktaalik to survive despite the low oxygen content of the shallow water because the tiktaalik would simply get its oxygen from the air. This selective advantage was passed on to the tiktaalik's offspring and over time, more amphibious creatures evolved with the ability to survive both on land and in water.
Answer:
Intelligence is multifaceted
Explanation:
Most parents try to provide the maximum advantage for their children when they are in the womb to provide the best avenue for success when they are born. One popular belief is that listening to classical music in the womb makes them score higher in IQ tests.
Factually speaking, intelligence is was measured when the individuals were babies but when they were already older children. This does not accurately reflect other input that has occurred to that point. As a point of fact, parents that are in the position to provide classical music to their children may also be in a better position to provide a nurturing environment for optimal success.
Stimulation of glucose production and release into circulation to provide a quick fuel source for muscle tissue so that the body is readied for action during a stress event.
Option B.
<h3><u>Explanation:</u></h3>
Cortisol is a steroid group of hormone that is secreted from the Adrenal Cortex from the zona fasciculata. It's the middle layer of Adrenal Cortex. Cortisol helps in different functions of the body that includes the suppression of immune system, increasing the blood sugar level, gluconeogenesis, metabolism of fat, and proteins. This hormone helps in the gluconeogenesis which helps to produce glucose from non glucose sources. The primary sources include the fats and proteins and the glycogen reserve in liver and muscles. Thus increase in cortisol levels help in the retaining glucose levels in stress or hypoglycemia.
