KengaRu [80]3 years ago
8 0

Answer:

2.Tropical fish need warm water to survive.

Explanation:

  • The first option describes a relationship between two abiotic (non-living) factors i.e. the effect of high temperature on the oxygen concentration of water.
  • Option 3 describes the relationship between two biotic (living) factors i.e. the smaller fish is prey for the larger fish.
  • Option 4 again describes the relationship between two abiotic factors i.e. the effect of increase in light on water temperature.
  • Therefore, the option 2 is the correct one as it describes relationship between tropical fish (biotic factor) and water temperature (abiotic factor)

Which type of population growth is shown in this graph? Population of Bacteria
Lesechka [4]

Answer:

Bacterial population shown in the graph is of Exponential type.

Explanation:

When the rate of population increases over time in proportion to the population size,  it is known as exponential growth of population. Bacterial reproduction happens in an hour time span for many bacterial species by splitting itself in half.

This shows how the exponential growth occurs in bacteria. The amount of population gets increased with added organisms in generations of species.

Which statements is not true about prokaryotes?
irina [24]

Answer:

The correct answer is b. prokaryotes store their genetic information in a nucleus

Explanation:

Prokaryotes are organisms that do not have a true nucleus. A true nucleus is an organelle that is membrane-bound and contains the cell's genetic material inside it.

In prokaryotes nucleus is not present do its genetic material is spread in the cytoplasm of the cell. Bacteria and archaea are considered to come under the prokaryotes group because they do not have a membrane-bound nucleus and other organelle.

Eukaryotes are the organisms that have membrane-bound nucleus and they store their genetic information in the nucleus. Therefore the correct answer is b. prokaryotes store their genetic information in a nucleus.
