<span>Condyloid joint
There are 6 types of synovial joints in the human body. For this question, the 2 types that are most likely are condyloid or ball-and-socket joints. Both of these joint types are very similar to each other, so let's look at them in detail to see which one is the correct answer.
Condyloid - Has an ovoid condyle from one bone fitting into an elliptical cavity. It permits movement in two planes, but does not permit rotation.
Ball-and-socket - A ball shaped surface of one bone fits into a cup shaped depression of another. This type of joint permits movement in multiple planes and rotation.
The key difference between these 2 joint types is the symmetry between them. For the ball and socket, the projection is shaped like a ball which is completely symmetrical whereas for the condyloid, the projection is more ellipsoidal or ovoid which prohibits rotation. And since ovoid is mentioned in the question, the best choice would be the condyloid joint.</span>
Answer:
1. 20 units
2. 4 units
Explanation:
In an ecosystem, energy is transferred from one organism occupying a trophic level to another as they feed on one another. The amount of energy that is being transferred as the chain progresses is called ECOLOGICAL EFFICIENCY. According to this question, the ecological efficiency at each trophic level of the ecosystem is 20%. This means that about 20% of energy units will be transferred to the next trophic level.
If the green plants of the ecosystem capture 100 units of energy, the amount of energy that will be available to support herbivores (plant eaters) is: 20% × 100units i.e. 20/100 × 100 = 20 units.
Also, the amount of energy that will be available to support carnivores subsequently will be 20% of 20 units i.e. 20/100 × 20 = 4 units.
habitat is physical enviroment in 2hich an animal or plant is usually found.
Answer:
D. All the choices are benefits
Explanation:
as you climb higher in the atmosphere, there are three things that happen to your body, one is the circulatory affect, when there is hardly any oxygen in the blood, your body will start to react to this change in supply and either shut down, ((your lungs will give out, and you will pass out because of the lack of O2 in the brain)) or you will become Carbon-drunk. ((your cells will began to literally explode or shrink because of the fact there is no way to filter out your cells of the used up oxygen))
the second thing is with respiratory, your breathing will slow down and it will become hard to breath. its true that oxygen is lighter than carbon-dioxide, but oxygen is heavier then nitrogen and helium. Your body will start to feel heavier than normal and you will become weak. you will start to feel light-headed and eventually pass out if this feeling is new to you.
Third is the carbon affect, your body will end up dying because of it "reusing" carbon cells, and you will end up going into a coma because of the brain damage from no oxygen and too much carbon
