Answer:
Metabolism refers to chemical reactions that occur within the cells of living organisms -that involve the interaction of substrates, co-factors and enzymes to obtain a product- while homeostasis refers to the internal balance within the body.
Explanation:
<u>Metabolism</u> involves a series of processes that occur in order to obtain a result or product necessary for life. Exist chemical reactions that are part of various metabolic pathways, where chemical substances are transformed into others through the intervention of specific substrates and enzymes. In metabolism reactions can be
:
- Anabolic, when necessary molecules are constructed or synthesized, such as the biosynthesis of proteins from amino acids
- Catabolic, when a substrate is broken down to obtain a product, such as glucose to produce energy (ATP)
.
<u>
</u><u>Homeostasis</u><u> </u>is the maintenance of the proportion of elements for the body to function properly. It is the equivalent of internal balance, which makes use of internal regulation mechanisms.
<em>
A correct functioning of the metabolic reactions guarantees an adequate homeostasis, and the balance that is required for the organism to function properly, implies a regulation of the metabolic processes that occur.</em>

I may be wrong but I believe that this is right. sorry if its not.
Answer:
- Sister chromatids are not homologous chromosomes.
- Crossing over occurs between non-sister chromatids.
Explanation:
- "<em>Sister chromatids are not homologous chromosomes</em>". IT APPLIES.
- One chromatid is a chromatin strand that got thick after folding. The chromatin strand is the DNI double helix associated with histones. Before cellular division, the chromatin strand generates a copy or clon, so both of the daughter cells can get the same genetic information. These two strands keep joint together by a centromere. The chromosome is conformed by the chromatin strand and its copy, condensated and joint by the centromere. It looks X-shaped. The chromatin strand and its clon are known as sister chromatids, and they are together on the same chromosome. So one chromosome is composed of two chromatids.
- Homologous chromosomes are those that give information for the same trait, but this information is not necessarily the same. For example, both homologous chromosomes might give information for hair color trait, but one of them gives information for brown hair and the other one gives information for black hair.
2. "<em>Crossing over occurs between non-sister chromatids"</em>. IT APPLIES.
- Crossing-over occurs <u>between two homologous chromosomes</u> in the equatorial plane, that makes the daughter cells to be genetically different from the original one.
3. "Sister chromatids are found on two different homologs". IT DOES NOT APPLY.
- The chromatin strand and its clon, known as sister chromatids, are together on the same chromosome. <u>So one chromosome is composed of two chromatids. </u>
4. <em>"A chiasma forms between four molecules of double-stranded DNA on duplicated homologous chromosomes". </em>IT DOES NOT APPLY
- Chiasma is the point where two chromatids interchange genetic information making a place to new genetic material or information that will be inherited to descendants. Chiasma allows the crossing-over between <u>two homologous chromatids</u>, one of each parent.
Antibiotics can lead to septic shock if used to treat bacterial infections that are gram-negative. They are not effective too these bacteria because these bacteria would not allow the substances to enter the outer membrane. The bacteria have properties that do not allow the utilization of the antibiotics.
The correct answer is B.chloroplasts.
Chloroplasts are plant’s organelles so they cannot be found in a cell from fingernail. The function of chloroplasts is to convert light energy of the Sun into glucose that can be used by cells and this is possible thanks to chlorophyll found in chloroplast . The entire process is called photosynthesis.
