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.

Which best explains how rotation affects the colors we see in the sky at dawn and dusk?
A. At dawn and dusk the rotation of Earth slows down so the light from the increased sunlight creates colors.
B. At dawn and dusk, Earth has rotated closer to the Sun, so the heat creates the colors in the sky.
C. At dawn and dusk, sunlight is closer to Earth’s curved surface, refracting in the atmosphere, creating colors.
D. As dawn and dusk, the light from the Sun is fading and phases through all the colors of a prism in a cycle.
Answers
Option (c) best describes about the rotation that, how it affects the colors we see in the sky at dawn and dusk.
What is dawn and dusk?'Dawn' is the early morning time or sunrise time and 'Dusk' is the twilight time or sunset time.
When earth is rotating at its own place, so at the dawn and dusk time sun is near to the horizon line and distance between the earths surface and sun is less as compared to the day time. And at that time red light travels much easily to the earth side due to long wavelength and blue color travels at the day time when distance is more. Due to scattering and refraction of light we are able to see colors.
Hence, at dawn and dusk, sunlight is closer to Earth’s curved surface, refracting in the atmosphere, creating colors.

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).

How is precambrian time different from other divisions of the geologic time scale?
Answers
Precambrian time is different from other divisions of the geologic time scale as the life forms in this time had soft bodies.
What are geologic time?Geologic time is the time that is begins at the start of the Archean eon and it is the extensive interval of time occupied by the geologic history of the earth.
Precambrian time is the the earliest time of the geologic ages, which are marked by different layers of sedimentary rock including the fossilized remains of plants and animals buried when the sediments were formed. Main difference between both the times is in Precambrian time life-forms had soft body parts and in Geologic time life-forms had hard body parts.
Hence main difference is of life forms.

A block is pulled 0.90 m to the right in 4.5 s. What is the block's average speed to the nearest tenth of m/s?
Answers
Answer:
The average speed of the blocks are 0.36 m/s.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed with respect to time. As at time t = 0 , the speed is also zero, and at time t = 2.5 s , the speed will be.
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

(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.
