puteri [66]

The complete question is :

Algae are plantlike organisms that live in the water. These algae have been in sunlight for several hours now. What can the algae do because they are in sunlight? What does this mean for the number of energy storage molecules in the algae?The algae can . . .

take in carbon from the air. The carbon is used to make energy storage molecules.

take in carbon from the air. The carbon is used to break down energy storage molecules.

give off carbon to the air. Giving off carbon allows them to make energy storage molecules.

give off carbon to the air. Giving off carbon uses up energy storage molecules.

Answer: Option A

Explanation:

Algae are plant like organism found in water, they are capable of performing photosynthesis.

Th algae in water trap carbon dioxide from the atmosphere( water) in order to convert into energy molecules known as glucose in the presence of sunlight.

This means the number of energy storage molecules in the algae increases after photosynthesis.

This is how the algae uses sunlight in order to prepare glucose from them.

Why do reptiles not have to return to water to lay their eggs?
daser333 [38]
Reptiles do not have to return to water to lay their eggs because they produce eggs that are already contained with liquids.

The babies must be able to hatch themselves then return back to the water, why have the eggs be in the water and then have the baby reptile be exposed to such an environment so quickly?

Hm, there is no definite answer according to my research that I've done, possibly check out your local library.

lorasvet [3.4K]

In order to study viruses in the environment, scientists isolate nucleic acids from an environmental sample, sequence them, and use computers to assemble genomes and compare them to known sequences in databases. This approach is known as Metagenomics.

  • The study of whole nucleotide sequences that have been extracted and examined from all of the organisms (usually bacteria) in a bulk sample is known as metagenomics.
  • Metagenomics is frequently used to investigate a particular population of microbes, such as those found in soil, water, or on human skin.
  • The study of viral genetic material that is derived directly from the environment rather than from a host or natural reservoir is known as viral metagenomics.
  • In research focusing on certain potential reservoirs, viral diversity in the environment is frequently overlooked.
  • Without the need to isolate and grow viral species in the lab, it provides crucial information on virus evolution and the genetic diversity of the viral population.
