The correct option is this: BECAUSE OF A SPINAL REFLEX.
Reflex action refers to the involuntary movement of any part of the body when such a part receive a stimulus. The response to reflect action is always immediate and it occurs without the consent of the affected person. Examples of reflex action is the contraction of the pupils when light shines in one's eyes and the quick withdrawal of one's hands when one touch a hot object.
Answer:
C. You can see the parts in a heterogeneous mixture but can't see them in a homogeneous mixture.
Explanation:
a heterogeneous mixture is in other words, the one that does not mix or is not uniformly combined, hence leading to the creation of layers of the substances used.
a homogeneous mixture is the one that completely dissolves, or mixes, or is uniformly combined.
Answer:
TRUE
Explanation:
If the population follows a logistic growth curve, the graph of P vs t will look like the diagram below.
The rate of growth (P') increases slowly at first, then increases rapidly from 2 to 4, and then slows down, but always P > 0.
The graph has an inflection point at (3, 1000). That's the point at which the rate of growth starts slowing down.
When t < 3, P'' > 0.
When t = 3, P'' = 0.
When t > 3, P'' < 0, because the rate of population growth is slowing down.
Thus, if the population is in the final phase of logistic growth, the population is increasing at a decreasing rate (TRUE)..
Saturated fatty acids are different to unsaturated fatty acids because they have no C=C double bonds.
<h3>What are the differences between saturated and unsaturated fatty acids?</h3>
- Saturated fatty acids do not have C=C double bonds, while in unsaturated fatty acids there is at least one C=C double bond in the fatty acid chain.
- Saturated fats are usually solid at room temperature and are derived from animal sources, whereas unsaturated fats are usually liquid at room temperature and are from plant sources.
- One must reduce the amount of saturated fat in their diet and consume more unsaturated fats like olives, seeds and nuts.
- Unsaturated fats can be monounsaturated (contains only C=C double bond) or polyunsaturated (contains two or more C=C double bonds).

The release of pyrophosphate from the incoming nucleotide, and then hydrolysis of the pyrophosphate to inorganic phosphate provides energy for the addition of nucleotide onto a DNA strand.
Nucleotides are linked together by a condensation event that yields a tiny, stable molecule. But the released molecule is pyrophosphate, not water. A good amount of free energy is released when water is added to pyrophosphate.
The high-energy link between the ejected beta and gamma phosphates stores the energy for each incoming nucleotide's addition. The subsequent hydrolysis that occurs drives the process. A substantially greater quantity of energy is released when two phosphates are separated into individual phosphates.
