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).
<h3>Answer</h3>
Approximately 40% of the energy stored in sugar molecules is converted into energy and the remaining 60% is wasted as heat energy.
<h3>
Explanation</h3>
Cellular respiration is the process which take place inside a living organism by which organic compounds, usually carbohydrates, are broken down releasing energy that is used to produce ATP molecules that supplies energy/power to cells.
<h3>Example of respiration</h3>
C6H12O6 + 6O2 —– enzymes & coenzymes ——> 6CO2 + 6H2O + Release of Energy (≤38 ATP) + Heat
So, 40% of the available energy of glucose is release as ATP and the remaining 60% is lost as heat and helps to generate your relatively high body temperature.

<span>The appropriate answer is A. the hemisphere is is tilted toward the sun and the sun reaches its highest point in the sky. This usually occurs on June 20 or 21. At this time the northern hemisphere experiences its longest day. Summer in the nothern hemisphere means that the earth is tilted towards the sun and receives sun rays that are more direct. </span>
Answer:
Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell. Indeed, apart from random mutations, each successive duplicate cell will have the same genetic composition as its parent, due to the inheritance of the same chromosome set and similar biological environment. This works well for replacing damaged tissue or for growth and expansion from an embryonic state. Because the genes contained in the duplicate chromosomes are transferred to each successive cellular generation, all mitotic progeny are genetically similar. However, there are exceptions. For example, there are genetic variations that arise in clonal species, such as bacteria, due to spontaneous mutations during mitotic division. Furthermore, chromosomes are sometimes replicated multiple times without any accompanying cell division. This occurs in the cells of Drosophila larvae salivary glands, for example, where there is a high metabolic demand. The chromosomes there are called polytene chromosomes, and they are extremely large compared to chromosomes in other Drosophila cells. These chromosomes replicate by undergoing the initial phases of mitosis without any cytokinesis (Figure 2). Therefore, the same cell contains thick arrangements of duplicate chromosomes side by side, which look like strands of very thick rope. Scientists believe that these chromosomes are hyper-replicated to allow for the rapid and copious production of certain proteins that help larval growth and metamorphosis
