Answer:
(D) Enzymes can function only within living cells.
Explanation:
<em>Enzymes are biological molecules that are proteinous in nature and speed up the rate of biological reactions.</em>
Option A is true because enzymes are not used up or changed when they are used to catalyze reactions
Option B is true. Enzymes are very specific with regards to the reactions they take part in.
Option C is true. Some enzymes contain non-protein component that assist them in their functioning. These non-protein components are called co-factors.
Option E is true. Because enzymes are proteinous in nature, they can be destroyed/denatured by high temperatures.
<em>The only untrue option is D. Some enzymes can function outside living cells. For example, the enzymes involved in digestion can function not just within living cells but also outside it. The functions of some of the digestive enzymes can be demonstrated in the laboratory.</em>
The correct option is D.
Here is your answer
D. Losing electrons
REASON:
Cations means positive ions.
Positive ions are formed by losing electrons which increase positive charge on the body.

In order for a barrier island to form, the coastal sand is organized into barrier islands. There are three conditions for an Island of this type to form.
1. There must be a sufficient supply of sand to form the island.
2. The sea level must be rising.
3. There needs to be winds and waves with sufficient energy to move the sand around

Answer:
The tissue fluid is less concentrated
Explanation:
Water naturally moves via the passive process of OSMOSIS, which is the movement of water from a region that is less concentrated to a region that is highly concentrated via a semipermeable membrane.
In this question, there is said to be a net movement of water into a cell from the surrounding tissue fluid. Based on osmotic principles, this means that the solute concentration of the tissue fluid is lower than that of the cell. Hence, the tissue fluid contains more water, causing it to move towards the cell.
<span>The correct answer is a lizard. The prefix "hydro-" means water, so the hydrosphere means the parts of the earth covered in water, such as oceans, lakes, etc. The prefix "litho-" means stone or rock, so the lithosphere indicates the land on the earth. An animal who lives in both the hydrosphere and lithosphere will likely be an amphibian (such as frogs and lizards), which lives both on land and in water. An eagle is incorrect because it does not live in water. A duck is incorrect because, although it often visits the water, it does not live there (it's a mammal like us). A shark is incorrect because it does not live on land.</span>
