Answer:

C.) crystalline solids

Explanation:

The solid materials may be crystalline or amorphous. The concept of crystal structure is related to the organization of atoms in a geometrical form. Crystalline structures are present in various materials, where atoms distributed within their structure form a network called the crystalline lattice. Therefore, crystalline structures have salts, metals and most minerals. Crystalline structures are formed by unit cells that are their basic unit, as they constitute the smallest set of associated atoms found in a crystalline structure.

The molecules of the crystalline structures can have two types of bonds, the directional ones, which include the covalent and dipole dipole and the non-directional ones where the metallic, ionic, van der Walls bonds. When formed by ionic compounds, these crystalline structures can result in crystalline solids.

worty [1.4K]

Answer:

The 5' end has free phosphate group while the 3' end has free OH group.

Explanation:

Each DNA strand has two ends that differ from each other with respect to the functional group. The nucleotide present at the 5' end of a DNA strand has a free phosphate group. This phosphate group of other nucleotides of the DNA strand is bonded in phosphodiester bonds. Likewise, the 3' end of a DNA has a free OH group. This makes the two ends of a DNA strand quite different from each other. A DNA new nucleotide can be added to the 3' end due to the presence of a free OH group.

Which reactant of photosynthesis is also involved in climate change?
choli [55]

Answer:

B. Carbon dioxide

Explanation:

First of all, let’s write out the photosynthesis equation to identify the products and reactants.

6CO2 + 6H2O + energy —> C6H12O6 + 6H2O

In a chemical equation with the arrow pointing right, the reactants are on the left and the products on the right.

In photosynthesis, the reactants, carbon dioxide, water, and energy, react to form the products of glucose (sugar) and oxygen.

Now, let’s look at the answer choices. We can automatically eliminate choices A (oxygen) and D (sugar) because they are products.

We are left with B (carbon dioxide) and C (water). Water isn’t really considered a major contributor to climate change. Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing climate change.

Therefore, the best answer choice is B. Carbon dioxide
