Which statement best describes both models?

A. Model X is the heliocentric model in which Earth is the center of the solar system; model Y is the geocentric model in which the Sun is the center of the solar system.

B. Model X is the geocentric model in which the Sun is the center of the solar system; model Y is the heliocentric model in which Earth is the center of the solar system.

C. Model X is the heliocentric model in which the Sun is the center of the solar system; model Y is the geocentric model in which Earth is the center of the solar system.

D. Model X is the geocentric model in which Earth is the center of the solar system; model Y is the heliocentric model in which the Sun is the center of the solar system.

Answers

Answer 1

Answer:

Answer D

Explanation:

Heliocentric is the model we use today, where we all revolve around the sun. Geocentric was a model that was long ago discarded after the discovery of telescopes.

Which of the following organisms evolved after amphibians?

Only cats
Only reptiles
Only marsupials and cats
Reptiles, marsupials, dogs, and cats

Answers

Answer:

Reptiles, marsupials, dogs, and cats

Explanation:

The correct answer is only reptiles as they evolved after amphibians.

Amphibians were one of the earliest groups of land-dwelling vertebrates to evolve. After amphibians, reptiles emerged. Reptiles are a diverse group of cold-blooded vertebrates that includes animals such as lizards, snakes, turtles, and crocodiles. They have adapted to a wide range of environments, including deserts, forests, and oceans.

The other options provided in the question, such as cats, marsupials, and dogs, did not evolve after amphibians. Cats and dogs belong to the mammal group, which evolved much later than amphibians. Marsupials, on the other hand, are a group of mammals that includes animals like kangaroos and koalas. While marsupials did evolve after amphibians, the question specifically asks for organisms that evolved "after amphibians," excluding any other groups that may have evolved concurrently.

So, the correct answer is "Only reptiles" because reptiles evolved after amphibians.

1. What is one major pattern in the fossil record?

Answers

One pattern in the fossil record is the presence of forms with transitional characteristics, arranged in sequential stratigraphic order. This means that the fossil record provides evidence for evolution and it shows tiny changes in the structures of organisms as time moved forward.

Fossils give us information about how animals and plants lived in the past. ... Some animals and plant are only known to us as fossils. By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other.

The fossil record is the highly ordered sequence in which fossils are found in layers of sedimentary rock.

(7th grade chemistry) What makes a polyester, nylon and acrylic a synthetic materials/ products, in other words what happen during polyester, nylon and acrylic chemical reaction?(or what happen during a chemical reaction)

Answers

Explanation:

What you call polyester is technically polyethylene terephthalate or PET plastic molded into filaments that are then woven into fabric. It's made in a chemical reaction between ethylene glycol and therephthalic acid, and these chemicals are derived from fossil fuels, air, and water.

Nylons are condensation polymers or copolymers, formed by reacting difunctional monomers containing equal parts of amine and carboxylic acid, so that amides are formed at both ends of each monomer in a process analogous to polypeptide biopolymers. Most nylons are made from the reaction of a dicarboxylic acid with a diamine or a lactam or amino acid with itself

The binder resin in acrylic paint is man-made, most of the time in some sort of lab. It is made generally from the monomer methyl methacrylate and also any real common catalyst. The catalyst speeds up the reaction to where the monomers create extremely long chains. Which result in polymethyl methacrylate, an acrylic plastic polymer.

The pigments are also mostly made in labs/factories. Most of the time they are either pure elements like pure cobalt powder and carbon charcoal, or they basic bounded compounds like cadmium sulfide. To make cadmium sulfide you react cadmium chloride with hydrogen sulfide to make a bright yellow solid. It is then washed and heated to make a spectrum of different colors.

Basically all of acrylic paints are man-made through various chemical reactions.

**URGENT< WILL MARK BRAINLEST****What is true when a reaction reaches equilibrium? Select all that apply. *
There is more product than reactant.
The reaction has stopped.
The reaction is faster in the forward direction.
The reaction is faster in the backward direction.
The concentration of products and reactants is constant.
There is more reactant than product.
The reaction rate is equal in both directions.

Answers

Answer:

below

Explanation:

The reaction rate is equal in both directions.

In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time.

Reaction rates of the forward and backward reactions are equal and there are no changes in the concentrations of the reactants and products, the amount of reactants and products present is constant.

For example, balanced chemical reaction: N₂(g) + O₂(g) ⇄ 2NO(g).
