Answer:

Explanation:

Water is a compound and scientifically known as H $_{2}$ 0 (2 hydrogen atoms and 1 oxygen). Therefore, the answer is...

Not A because water is not an element of one pure substance; rather, it is a compound and can be broken down into two pure substances.
Not B because the statement contradicts itself: a compound is made of different atoms and, thus, different molecules.
Not C because a mixture contains different substances that are physically -- not chemically -- combined. And as we know, water is a compound, which means that its atoms are chemically bonded to one another. Or else it would just be 2 free hydrogen atoms and 1 oxygen.
D (yay!) because it is not the *most* accurate, but simply the <em>best</em> description of those provided. Water can be described as a homogenous (uniform in appearance) mixture because, minus the "mixture" part, that's what it is, essentially: a substance that looks pure but is really made of up different molecules.

Ngl this was tricky, but I hope this helps :)

Describe in words what occurs during the process represented by the photosynthesis equation. Include the importance of sunlight

8_murik_8 [283]

Photosynthesis usually takes place in the leaves. Leaf cells contain many chloroplasts (up to 50 per cell). These organelles contain a green pigment, chlorophyll, capable of capturing light energy. This energy is used to make sugar molecules from water drawn from the soil by the roots and carbon dioxide from the atmosphere, captured by the leaves. The sugars produced subsequently distributed in the different parts of the plant.

Here is the reaction of photosynthesis:

6 CO2 + 6 H2O + light energy ==> C6H12O6 (glucose) + 6 O2

But this balance is in fact broken down into two successive stages:

photochemical reactions (clear phase):

12 H2O + light ==> 6 O2 + chemical energy;

the Calvin cycle (dark phase):

6 CO2 + chemical energy ==> C6H12O6 + 6 H2O.

The first phase of photosynthesis, called clear phase, requires the illumination of the leaf. Chlorophyll, which is embedded in the thylakoid membrane, absorbs light energy. This energy absorption is accompanied by the degradation of water molecules and the release of oxygen.

In a second phase independent of light, called the dark phase, the energy absorbed by chlorophyll is used for the transformation of carbon dioxide molecules into sugar molecules.

The sugars made by photosynthesis are stored in the cell as starch, transformed into other organic molecules, such as proteins, or degraded in the mitochondria during respiration to meet the energy needs of the plant.

Answer:

Periosteum.

Explanation:

Periosteum is an extremely thin region of non-calcified tissue on the exterior of bones. It covers the entire surface of every bone in the body, with the exception of the joint-forming ends of bones where cartilage forms the bone’s outer layer.
