Biology
1 answer:
Dennis_Churaev [7]3 years ago
4 0

Answer:

The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts. Hard parts also decay more slowly than soft parts, giving more time for them to be buried.

Michelle drew a simple diagram to show how a hurricane forms. Which location on the diagram indicates a low-pressure area?
inysia [295]

Answer:

"Location 4" indicates a low-pressure area

Explanation:

A low-pressure area is defined as the region in which the pressure in the atmosphere is comparatively lesser than nearby surrounding areas. This region is a depression that is comprised of more winds, warmer air, and lifting of air mass takes place.

In a low-pressure zone, the warm air becomes less dense, due to higher temperature, as a result of which it rises up into the atmosphere. As it rises up into the atmosphere, it eventually cools and condensation starts taking place. After a definite period of time, rainfall occurs.

Thus, in the given image, location 4 shows the low pressure area.

The synchondrosis is of two types- the temporary and permanent synchondrosis in which the temporary synchondrosis represents the growth plate or epiphyseal plate of the hyaline cartilage which connects the shaft of the bones to the end of the bone.

The thickness of the epiphyseal plate in the children does not change as the bone lengthens.

Thus, D) Cartilaginous synchondrosis is the correct answer.

aliya0001 [1]
John and Pat's occupation best explains the difference between their skin pigmentation. Since Pat works as a lifeguard, she is more exposed to the sun, which tans her skin. John, on the other hand, works in the theater, where he isn't exposed to sunlight that much, so he is much lighter than his twin, Pat.
