answer:

Coal is formed by the decomposition of dead plant and animal under the earth for millions of years under heat and pressure.

astra-53 [7]

The clear fluid found in whole blood in which the cells are suspended is called <u>plasma </u>however, when the clotting factors are removed, it is now called <u>serum</u>.

Plasma is the frequently forgotten part of blood. White blood cells, red blood cells, and platelets are essential to body characteristics. However, plasma also plays a key function. This fluid consists of the blood components during the frame.

The serum consists of all proteins not utilized in blood clotting; all electrolytes, antibodies, antigens, hormones; and any exogenous substances (e.g., capsules or microorganisms).

Serum does now not incorporate white blood cells (leukocytes), red blood cells (erythrocytes), platelets, or clotting elements.

10 points! When looking out of my back door, I see robins, blue jays, finches, crows, hawks and owls all living in the same area
forsale [732]

The possibility for all of the mentioned birds to live all in a same area is because they are all specialized and occupy a certain niche in the food chain, thus not standing in each others ways when it comes to competition for food.

All of these birds have adapted to be able to survive in their respective environment, developing characteristics that will enable them to be superior in something. Through natural selection, the individuals that were performing better, got the chance to mate, thus the offspring was better adapted and stronger in its niche of the food chain.

The robins and the blue jays are birds that are very opportunistic in their food choice, thus giving them greater flexibility and ability to survive, they mostly feed on worms, insects, fruits, vegetables, so they have a big menu.

The finches are specialized in eating nuts and seeds, thus avoiding the competition with the previous two, thus having that food type for themselves.

The owls and hawks are both birds of pray, but the owls hunt mostly at night, while the eagles during the day. Also, the owls prefer to have rodents as their pray, while the hawks are mostly eating other birds, thus not standing in each other's ways.

What obstacles did Gerald ford go through
Mila [183]
<span>Challenges:
1. Vietnam
2. The worst economy since the Great Depression
3. Communist Europe (the Helsinki Accords)
4. Richard Nixon

One month after taking over the presidency, Ford pardoned Nixon. This caused a lot of controversy but Ford claimed he did it to save the nation from the prospect of a long, messy, and divisive trial.
In 1974, President Ford also offered clemency to those who evaded the draft during the Vietnam War if they would swear allegiance and perform two years of public service. Similarly, those who deserted during the war could return for two years in the branch they left to achieve clemency. However, Ford was criticized both by those who felt he was being to easy on the draft dodgers and those who had avoided the service because they felt they were in the right.

In 1974, Ford asked for aid to be sent to South Vietnam as fighting had resumed. Congress would not agree. In April 1975, Saigon fell and by 1976, North and South Vietnam were united into one country.

Ford escaped two assassination attempts, both by women. First on September 5, 1975, Lynette Fromme, a follower of Charles Manson, pointed a gun at him but did not fire. She was convicted of attempting to assassinate the president and sentenced to life in prison. The second attempt on Ford's life occurred on September 22, 1975 when Sara Jane Moore fired one shot that was deflected by a bystander. Moore was trying to prove herself to some radical friends with the assassination of the president. She was convicted of attempted assassination and sentenced to life in prison.</span>
