My neighbor has one that screams its hilarious!
Ribosome packages nutrients and sends itto different parts of the cell
Polar cell: - occur 60 and 90-degrees from the equator, near the north and south poles. - associated with high pressure zones and low precipitation. what is the interaction between Ferrell and Polar cell circulation?
If the drop is small enough, it is a perfect sphere.
<span> A sphere is the geometrical shape that has the smallest surface area for its volume. The drop takes this shape because water molecules tend to stick to each other. So, when not confined by a container, and with nothing around it to distort its shape, a very tiny water drop is perfectly round like a ball because the water molecules are pulling inward toward each other. </span>
<span>If the drop is larger like a raindrop in free-fall, it has a domed top and a semi-flattened bottom because as it falls it must push the air out of its way. That "upward" push of the air being displaced causes the falling drop to have a rather flattened bottom. </span>
<span>Contrary to popular misconception, a free-falling raindrop is not shaped like a teardrop -- round on the bottom and pointy on top.

Answer:
1. When two bones join together and fuse so that no visible separation occurs, it is referred to as a(n) <u>synostosis,</u> or bony joint.
2. Bones that join together and are held in place with threads of collagen, form a joint that is called a(n) <u>synarthrosis</u>.
3. The most complex joints are called <u>synovial</u> joints. They display varying amounts of mobility.
4. Bones joined together with cartilage between the ends of the bones, form a joint called a(n)<u> amphiarthrosis</u>.
Explanation:
The ossification of the connective tissue between two bones results in the fusion of them. As a result, now there is one bone instead of two. It's is called synostosis.
A synarthrosis is a joint that has very little or no movement at all. It has threads of collagen around them that keep the joint together.
A synovial joint is a diarthrosis joint. They have a wide range of mobility and are complex due to the number of components:
- A fibrous joint capsule connected to the two bones.
- Synovial fluid to lubricate the joint.
- Articular cartilage on the bones' joint surfaces.
An Amphiarthrosis is a joint with limited mobility. This type of joint has fibrocartilage that connects the two bones. We can find it in the pubic synthesis.
