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).

The diploid number for a lily whose pollen contains 12 chromosomes would be _________ and is produced when the pollen, containin
kirza4 [7]
The answers would be 24 and fertilises. 

Pollen is the male gamete of lily, which is a haploid cell, with only half the chromosomes of the normal diploid ones. Therefore, if the haploid gamete has 12 chromosomes, so the diploid would be 12+12 which makes 24. 

The egg is also a gamete of lily, but it's a female gamete. It is also a haploid cell, with only 12 chromosomes which is given in the question. So, when the sperm fuses and fertilises the egg, the zygote would have 24 chromosomes which is formed by 2 haploid gametes.

Which organ is responsible for dehydration and compaction of indigestible materials?
My name is Ann [436]

Answer:

Large intestine

Explanation:

After the completion of digestion process in the small intestine, the indigestible residual materials are passed to the large intestine.

The large intestine serves three primary functions -

  1. Absorption of water and electrolytes
  2. Production and absorption of vitamins
  3. Formation and propelling of feces accomplishing their removal through the rectum.

When water gets absorbed, the indigestible materials get dehydrated and during feces formation they are compacted and then eliminated through the rectum.
