Answer:

The correct answer will be options A, B and E.

Explanation:

Energy flow is the directional path of transfer of energy from one organism to another through a biological food chain.

The autotrophs or producers are present at the lowest trophic level which are capable of converting the sunlight energy to chemical energy or food via photosynthesis, therefore, receives maximum energy so accumulate high amount of biomass.

Energy flows in ascending manner usually from the lowest trophic level to highest trophic level that is from autotrophs to herbivore to carnivores in a food chain by a law called ten percent law. So, the carnivores at the highest trophic level receive less energy as compared to another trophic level.

Thus, options A, B and E is the correct answer.

Four groups of students plan scientific investigations to answer four questions for the science fair. Which question would most

antiseptic1488 [7]

Answer:

The question is incomplete, the questions asked by the students were as follows:

1. What kind of plant life grows naturally in the town park?

2. Which types of treats do different types of dogs like best?

3. Do different types of grass affect how far a ball rolls?

4. How are the chemicals in different vegetables similar?

The answer is 3

Explanation:

Three types of investigation are used by scientists to solve a problem or answer a question. These questions are: comparative investigation, descriptive investigation and experimental investigation. Experimental investigations are conducted to test the relationship between two variables. In the test, one of the variable is manipulated (independent variable) while the other responds (dependent variable).

In this case involving questions asked for a science fair, HOW DIFFERENT TYPES OF GRASS AFFECT BALL ROLLS is most likely an experimental investigation because it is testing the effects of grass type (independent variable) on ball roll (dependent variable).

Some interphase cells contain twice as much DNA as other interphase cells within the same tissue sample. Is this normal? Why?

FinnZ [79.3K]

Answer:

Yes, Since the interphase cells in G2 would have twice the DNA as the interphase cells in G1 phase or start of S phase.

Explanation:

Interphase has three stages: G1, S and G2 phase. DNA replication occurs in the S phase and doubles the DNA content of the cell. So, the DNA content of the interphase cells of the same tissue depends on stages of interphase.

The interphase cells which are in the G1 phase has half the DNA content as it is present in the interphase that has entered the G2 phase after completion of DNA replication in S phase.
