B, if he didn't end up taking all of the antibiotics that will happen
Answer:
Because natural selection selects for it. Thus it persists.
Explanation:
You have to understand heterozygote advantage. Basically, it's where heterozygotes have an advantage over homozygotes. In the case of sickle cell disease, heterozygotes have an advantage, and natural selection favors whatever is advantageous. Thus, because heterozygotes each have one recessive sickle-cell allele, as natural selection favors the heterozygotes, the recessive sickle-cell allele persists and remains in the gene pool.
In the context of protein digestion, protein breakdown into its amino acid constituents is completed by <u>proteases </u><u>produced in the small intestine</u>
<u />
- Protein-degrading enzymes are referred to as proteases. These enzymes are produced by bacteria, fungus, plants, and mammals.
- Proteins in the body or on the skin are broken down by proteolytic enzymes.
- This may aid in digestion or the breakdown of proteins that contribute to inflammation and pain.
- The small intestine, pancreas, and stomach all manufacture protease.
- The stomach and small intestine are where the majority of chemical reactions take place.
- Pepsin is the primary digestive enzyme that targets proteins in the stomach.
- Proteases are released by the pancreas into the proximal small intestine, where they combine with proteins that have already been altered by gastric secretions and break them down into amino acids, which are then absorbed and utilized by the body as necessary.

Answer: The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties.
Explanation:
Starch and Cellulose flare both polysaccharides which are constructed from the same monomer called glucose. The functions they provide in plants are different which includes the following:
- STARCH is used by plants for energy storage because unlike Cellulose, it's formed from glucose units( oriented in the same direction) connected by alpha linkages which can form compact structures that can easily be broken down.
- Cellulose provides structural support for plant cell wall because unlike Starch, it's formed from glucose units( which rotates 180 degrees around the axis of the polymer backbone chain) connected by beta linkages. This pattern gives Cellulose it's rigid features as is allows for hydrogen bonding between two molecules of Cellulose.
Therefore the statement that best describes why starch and cellulose provide different functions in plants is that (The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties).
Answer:
Transcription factors
Explanation:
This is because Eukaryotic gene expression is regulated by transcription factors and RNA processing, which occur in the nucleus, and during protein translation, in the cytoplasm.
Transcription in eukaryotic cells is controlled by proteins . These proteins then bind to some specific regulatory sequences and try to control the activity of RNA polymerase. The Gene expression is regulate by transcriptional regulatory proteins . Also ,the packaging of DNA into chromatin and methylatiin indicate levels of complexity to the control of eukaryotic gene expression.
