They go through a process called Mitosis. Mitosis is made up of four steps: Prophase, Metaphase, Anaphase, and Telophase. (An easy way to remember them is to remember PMAT) In Prophase, the membrane of the nucleus dissolves and the chromosomes replicate. In Metaphase, the chromosomes line up in the middle of the cells and spindle fibers start to form. Then, in Anaphase, the spindle fibers attach to the chromosomes and pull them apart, towords opposite ends of the cell. In Telophase the nucleus re-form around the two sets of DNA and the cells split in half.

Pepsi [2]

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).

In humans, the antibiotic amoxicillin (a type of penicillin) is used to treat certain bacterial infections. Complete the sentenc
mihalych1998 [28]

Answer:

Amoxicillin inhibits an enzyme required to build cell walls in bacteria.

Since humans have cell membranes, they are unaffected by amoxicillin.

Explanation:

Antibiotics are specifically designed to target bacterial cells, therefore, they don't kill human cells.

Amoxicillin, a type of penicillin, inhibits the biosynthesis of bacterial cell wall. The bacterial cell wall contains peptidoglycan that constitutes almost 95% of the cell wall in some Gram positive bacteria and as little as 5-10% of the cell wall in Gram negative bacteria. Amoxicillin inhibits the cross linkage between the linear peptidoglycan polymer chains that make up a major component of the cell walls of both Gram positive and Gram negative bacteria.

To compare the relative ages of fossils, scientists sometimes use an easily recognized
Natalka [10]
<h2>Answer:</h2>

The fossil is <u>A) </u><u>Index fossil</u>.

<h2>Explanation:</h2>

Index fossils refer to the type of fossil which is used to characterize and distinguish geologic periods. Due to this function of index fossil, they are also called as guide fossil or indicator fossil.  These fossils must have a short vertical range, wide geographic circulation, and quick developmental patterns.

Another term, Zone fossil is utilized when the fossil have every one of the characters expressed above with the exception of wide topographical dispersion, they are restricted to a zone and can't be utilized for relationships of stratas.
