Answer:

Both bacteria and blue algae are prokaryote organisms, meaning that they do not have a differentiated nucleus, and therefore they are more primitive. But blue algae are able to perform photosynthesis and so we can believe that the first forms of life on Earth date even further back than 3 and a half billion years ago.

Answer:

Chloroplast is crucial for photosynthesis not mitochondria...

Explanation:

Chloroplast isn't found in animal cells not because of it's evolutionary choice but because of it's rather different way of energy production. Chloroplast is modified by nature to produce energy using photons or photosynthesis that can only occur in plants but mitochondria does not used photons. It utilizes electron transport chain strategy instead.

Animals would never be able to make their surfaces photosensitive for photosynthesis to occur and produce energy with the help of chloroplasts.

Compare the reactants and products in the chemical equations below. Which statement best describes the relation between matter a
pshichka [43]

Answer and Explanation:

Chemical reactions are very complex processes which include the collision of molecules. During the chemical reactions, bonds between the breakdown of the atom and transformed in new ways. The chemical compounds that react together during the chemical reactions are called reactants, shown on the left side of the equation. They are broken down during the reaction and used as the reaction progresses. The chemical compounds that are formed from the rearrangement and breakdown of the reactants are called products. The products are shown on the right side of the chemical equation. As compare to the reactants, the products are more stable molecules. For example, in the reaction between H2SO4 and Zn, these two chemicals are the reactants, while ZnSO4 and H2 are the chemical reaction products.

                                                Zn + H2SO4       ZnSO4 + H2

                                                 (Reactants)            (Products)

The matter is a material that everything is made of matter. A property that matter has is known as energy. The same quantity of matter can have a diverse quantity of energy. Both energy and matter are identical. For example, if we add some energy into an ice cube, it will turn into liquid. After that, if we add more energy, liquid will turns into steam.
