Explanation:
The white blood cells that comprise 3-7% of circulating white blood cells (WBCs), are phagocytic, and can migrate out into body tissues to differentiate into macrophages are called "Monocytes." Monocytes are a type of white blood cell known for their phagocytic abilities and their role in the immune response. When they migrate into tissues and mature, they become macrophages, which are essential for engulfing and digesting pathogens, dead cells, and other debris in the body's defense against infections and maintaining tissue health.
Too cold for many living organisms
Mostly temperate near the equator and extremely cold at the poles
Extremely dry with no moisture in the air
The correct answer is option B
The temperature could have been too cold for some of the organisms without greenhouse effect.
The average temperature of the earth could have been much lower than what is today.
It is the green house effect that the temperature is optimum for the survival of all the organism otherwise only that organism could have survived who can live at lower temperatures.
it would be to cold cuz
canoe. Use Newton’s third law to explain why this happened. Hint: First
identify the action-reaction pair in this example.
Answer:
Resistive force from canoe in backward direction
Explanation:
As per Newton's third law of motion for every action, there is an equal reaction and that too in the direction opposite the direction of main action.
Here, the action reaction pair is the contact point of Emilio or the Canoe.
When Emilio tried to jump on the dock, he exerted an action force i.e the KE+PE in the forward direction but while jumping he pushed behind the canoe which in turn exerted resistive frictional force in the backward direction on Emilio which restricted him from jumping exactly on the dock.
