<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:
the sample contains starch and starch is stored in ground tissue.
Explanation:
It should be understood that Iodine solution is used to test leaves for the presence of starch. This will show a blue-black color, which means the presence of starch.
This process can simply be demonstrated by simply following these steps.
* Take two potted plants of the same kind.
* Keep one in the dark (or in a black box) for 72 hours and the other in the sunlight.
* Take one leaf from each of the plants.
* Put few drops of iodine solution on each of the leaves.
* The leaf kept in the sunlight will turn blue-black due to presence of starch.
* The leaf kept in the dark will not turn blue-black because of absence of starch.
In conclusion, the iodine is used to test for starch.
Answer:
Endorphin is a type of neurotransmitter with similar properties to morphine.
Explanation:
Endorphins are a large group of peptide hormones in humans and other animals. Endorphins are produced by the pituitary gland and nervous system. They are helping to reduce pain, they are releasing in responding to pain and stress, They are also releasing in other activities such as eating, exercise etc.
Other benefits of endorphins includes:
Reducing the weight.
Reducing stress and anxiety.
Helping in deal with pain during childbirth.
Reducing the symptoms of depression.
Volume - the amount of something in a three-dimensional area.
Meniscus - the curve that a liquid makes at the surface from surface tension.
I measured the volume of water in the container.
The water formed a meniscus near the top of the container.
