Answer:
Many flowers use visual cues to attract pollinators: showy petals and sepals, nectar guides, shape, size, and colour. I personally think it is very cool how they know what to do to attract pollinators.

Answer:
Deletion of a DNA base from a gene affects an organism by changing the sequence of amino acids in a protein.
Explanation:
A DNA fragment forms a gene, with a specific sequence of nitrogenous bases, which determines the synthesis of a specific protein. When a deletion of a base occurs in such a gene, it affects:
- Transcription of the mRNA, which will have the sequence of altered bases.
- During translation, the mRNA codons will encode at least one different amino acid.
- The structure of the synthesized protein, which will be altered by changes in its amino acid sequence.
In summary, the <u>deletion of a base in the DNA</u><u> will affect the </u><u>protein</u><u> to be synthesized by </u><u>changing the amino acid sequence</u><u> of its structure</u>.
The other options are not possible, because the deletion of a base in the DNA of a gene
<em> Does not influence the number of chromosomes that the gametes will have.
</em>
<em> It does not produce long chains in the chromosomes.
</em>
<em> It does not affect the ribose structure of the nucleic acids.</em>
The ability of microtubules to undergo rapid <u>depolymerization </u>and slower<u> polymerization</u> is associated with the ability of the <u>spindle apparatus</u> to explore the cell and locate chromosomes.
<u>Explanation:</u>
Microtubules are tubulin polymers that make up part of the cytoskeleton and provide eukaryotic cells with framework and shape. These are formed by polymerizing the dimer into protofilaments of two globular proteins, alpha and beta tubulin, which can then be combined laterally to form the microtubule, a hollow tube.
Tubulin dimers can attach two GTP molecules, one of which may be hydrolyzed following assembly. Tubulin dimers are in GTP-bound state throughout polymerization. Once hydrolysis reaches to the peak of the microtubule, a rapid depolymerization and shrinkage is initiated.

Answer:
Explanation:
Isotonic: an isotonic solution is one that has the same osmotic pressure compared to another one usually cells or body fluid.
If eye drops had high osmotic pressure they would cause the eye to be dry since fluid would move out the cells making up the eye.
If the eye drops had low osmotic pressure this would cause swelling of the eye since the cells would retain the fluid from the eye drop.
