Answer:

Compound light microscope

Explanation:

This is the ideal microscope because it requires the passage of  harmless beam of light through the specimen.Since the pond contain living creatures this is best to use.

C and D both require the transmission of beam of electrons through a sample. D depends on the reflection of the electron  after scanning the specimen surfaces and sent this to the lenses of the observer.(C)involved the  passing of the beam of electrons through the specimen the interaction of the electrons with the atoms in the specimen(,therefore in both cases  these specimens can not be wet and living.

The specimen should be dry in both cases and therefore non -living ,because the chamber for the specimen must be a vacuum,and living organism can not survive in the vacuum. Thus pond water can not be used as specimen because the specimen in the water but me be living.

Why are telomeres problematic for eukaryotic chromosome replication? a) They are highly repetitive and thus hard to replicate co
Natalka [10]

Answer: Option E

Maintaining very long telomeres promotes cancer cell formation.

Explanation:

Telomere refers to either of the sequences of DNA at each end of a eukaryotic chromosome.

Usually, in eukaryote chromosome replication, telomeres are not replicated.

Hence, they are usually lost resulting in the shortening of the telomere ends after repeated cycle of cell division. This also leads to cell aging and stoppage of cell division.

The shortening of telomere combined with stoppage of cell division, and cell aging initiation prevent CANCER, which thrives on lengthy telomeres
