Answer:

gills

Explanation: A fish without a jaw was the first vertebrate to evolve. These fish used filtration to capture their food and sucked water and debris from the sea through their mouths and then released the water and trash through their gills. Some features are as follows:

1. They have a notocorda that serves as support through the back of the fish.

2. Gill bags. These organs are responsible for filtering the oxygen in the water.

3. A pineal eye that is sensitive to light

4. A cartilaginous skeleton

HELP+EXPLAIN PLEASE Describe how a sarcodine, such as amoeba, gets food.

frosja888 [35]

Well, the food is in the environment. I would like to compare it with how bacteriae feed (however my biology is quite rusty), that is, they engulf their food and they "digest" -- not the proper term, since there are no organs to do real digestion -- it.

Differential survival and reproduction is best described by which term? natural selection creationism inheritance of acquired ch

Sophie [7]

I believe it is natural selection. Natural selection is when over a period of time, traits that are formed to help the organism survive, are passed to the next generation. For example, if there were two types of rabbits. One had black fur and the other was white. They both lived in the artic. The black furred rabbits are mostly eaten by predators because their black fur is easily seen against the ice and snow. Over a period of time, the black furred rabbit would die out. The next generation would mostly have white fur to help them survive.
