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).

Compare the two processes: mitosis and meiosis. Can you identify the the true statements about the two? Meiosis results in four
Alborosie

Answer:

The correct statements are:

  • Meiosis results in four haploid daughter cells.  
  • During meiosis, the 2N mother cells produce N daughter cells.  
  • In both processes, DNA replication must occur.  
  • Mitosis is responsible for genetic continuity; in higher organisms, it is essential for growth and repair.  

Mitosis is a type of cell division in which a parent cell is divided into two identical daughter cells. Each daughter cell contains identical genetic material as that of the parent cell.  

It plays important role in growth and repair of cells and tissues in multi-cellular organisms.

Meiosis is a type of cell division in which a parent cell is divided to produce four daughter cells. Each daughter cell contains exactly half the genetic material (chromosomes) as that of parent cells

It plays important role in the production of gametes (eggs and sperms) in sexually reproducing organisms.

Before either cell division, the DNA is replicated in the S or synthesis phase of the cell cycle.

11. Who suggested that peppered moths were an example of natural selection?
weeeeeb [17]

Answer:

J. W. Tutt suggested that peppered moths were an example of natural selection.

Explanation: Before industrial revolution, the population of white peppered moth is high as compared to dark peppered moth because white peppered moth can't be seen at night by the birds. After industrial revolution, sooth is spread on the surface of the trees which make easy for the bird to see white peppered moth and feeds on them. Population of white peppered moth decreases while the population of dark peppered moth increased because they cannot be seen in the dark due to black color of sooth.

The portion of the circulation governed by the right side of the heart is the ______ circulation.
AlekseyPX
<span>The correct answer is B. Pulmonary. The answers C. Cerebral and D. Extremity, are baseless regarding this question; A. Systemic could be a good alternative, as the blood flows from the systemic to the pulmonary circulation in the right side of the heart; but the systemic circulation is in fact mostly handled in the left side of the heart, while the right side handles the pulmonary one. </span>
