<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>
The observation that is most likely to have led her to form this hypothesis is the fact that flies with long wings can produce offspring with short wings. Recessive traits are the traits that are carried in a person genes without appearing in that particular individual. For example, a dark haired person may have one gene for dark hair, which is a dominant trait, and one gene for light hair, which is recessive.
The first answer is D. The padded webbing on their feet works much like a flipper would and helps them to move faster, by allowing them to move more water.
The second is B. Like pine trees most desert plants have spines so that they can retain as much water as possible.
The third is A. Not only are they sharp, but the way in which the jagged edges on their teeth lines up allows them to interlock to keep their prey from getting away.
Answer:
Option A, the liquid level in a capillary tube will drop below the surrounding liquid and the surface in the capillary tube will have a convex meniscus.
Explanation:
A liquid will wet the surface of the container in which it is contained only when the adhesive forces between the molecules of the liquid are weaker than the adhesive force between the surface wall of the container and water.
A convex meniscus is formed when the attractive forces between the molecules of liquid (cohesion) becomes greater than attractive forced between the water molecule and the container's surface (adhesion)
Convex meniscus simultaneously move the surface of the liquid in the downward direction due to which its level become lower than the surrounding layer.
Hence, option A is correct
Genetic Recombination
"The process in which offspring are produced which are genetically different from their parents is known as genetic recombination"
