Answer:

a. Exothermic.

Explanation:

We know that there are several types of chemical reactions. In some reactions, the energy which is absorbed to break down the bonds of the reactants becomes less than the energy which is released at the time of forming new bonds of the products.

This means that in the whole reaction, energy is released as either light or light. This type of reaction is called an exothermic reaction.

Which best describes how the fossil record supports the theory of evolution?
kipiarov [429]
Fossil records show us that over time animals have 'changed' and become better adapted to their surroundings and so we can see similar characteristics in a horse from 100, 000 years ago in our present day horses. This supports the theory of evolution

50 POINT + BRAINLYEST PLZZZZ UNGENTS!!
KonstantinChe [14]

Answer:

      Carbon is the foundation of all life on Earth, required to form complex molecules like proteins and DNA. Carbon helps to regulate the Earth's temperature, makes all life possible, is a key ingredient in the food that sustains us, and provides a major source of the energy to fuel our global economy. The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change. Where the carbon is located in the atmosphere or on Earth is constantly in flux.

       On Earth, most carbon is stored in rocks and sediments, while the rest is located in the ocean, atmosphere, and in living organisms. Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms. In the case of the ocean, carbon is continually exchanged between the ocean's surface waters and the atmosphere, or is stored for long periods of time in the ocean depths. Humans play a major role in the carbon cycle through activities such as the burning of fossil fuels or land development. As a result, the amount of carbon dioxide in the atmosphere is rapidly rising; it is already considerably greater than at any time in the last 800,000 years.

A. Reactants: glucose products: oxygen
kifflom [539]

Answer:

I believe the correct answer is option <u>C. Reactants: carbon dioxide and water products: oxygen and glucose.</u>

Explanation:

I'm pretty positive that the two main reactants are carbon dioxide and water, while the products are oxygen and glucose. Carbon dioxide and water + sunlight are the reactants which are present at the start of the reaction <u>6co2+6h2o c6h12o6+6o2.</u>

Hope I could help!
