Answer: Air pressure is influenced by temperature because, as the air is warmed, the molecules start moving around more, so they bump into each other more often and create more pressure. But, air pressure also affects temperature - the more those molecules bump into each other, the more heat they generate.
Explanation:
Vertebrates developed about 550 million years ago. The oldest vertebrate fossils are those of FISH with no jaws. These e<span>arly jawless fish did not have paired fins and their bodies were covered with heavy, bony scaled, but their skeletons were made of cartilage. For the next 50 million years, they were the only vertebrates.</span>

Explanation:I saw it on a quiezlet online lol
<h2>B) option is correct </h2>
Explanation:
- Mosses are waxy little plants with no leaves and no stem that use each other to stay upright, their grouping helps them retain water in the area
- A waxy covering across their bodies helps keep water from evaporating and are usually found in moist areas out of the direct sunlight
- In mosses, gametophyte (1N multicellular adult plant) is the dominant portion
- When top of the female gametophyte plant is sectioned longitudinally and examined with a microscope, several egg-producing structures called archegonia are present, two archegonia each produces one 1N egg cell
- The egg is clearly visible in the archegonium at the left and only part of the egg cell is visible in the archegonium on the right
- Once sperm have been splashed to the female plants, sperm swim into the archegonium and fuse with the egg, the process is called fertilization
- A single 2N cell called the zygote (or fertilized egg) is formed
- Zygote further undergoes mitosis many times to eventually form a multicellular 2N plant called the sporophyte
