Explain how our solar system formed and evolved. also use the terms nebula, planetesimal, protoplanet, gravity.​

Answers

Answer 1

I love this question!(mainly because it is about astronomy lol)

Our solar system formed from a cloud of gas and dust, called a nebula. there are many satellites orbiting our Sun, but there are eight considered to be the main planetesimals that make up our solar system. A protoplanet is a hypothetical eddy in a whirling cloud of gas and dust that later becomes a planet. The asteroids Ceres, Pallas, and Vesta are believed to be protoplanets. Gravity keeps objects like moons and asteroids close to planets. This is called a gravitational pull.

Answers

Transplanting embryonic eye tissue under the skin on the back of a tadopole (frog) is an example of positional information

What is positional information?

Extrinsic (positional) information, which is received from neighboring cells. For example, a cell may receive chemical signals from a neighbor that instructs it to become a particular type of photoreceptor cell (light-detecting neuron).

With this information, we can conclude that transplanting embryonic eye tissue under the skin on the back of a tadopole (frog) is an example of positional information.
