(B) A sample of water collected just downstream of the housing development
C)A sample of water collected just downstream of the northern forest
D)A sample of distilled water
Answer:
D. A sample of distilled water
Explanation:
You need to have a control sample that hasn't been messed with to see what would happen if you had no reaction to your experiment
A sample is the smaller set of data which a researcher makes use of to complete a research.
As a result of this, we can see that a sample study is the use of these samples to come to a conclusion about the investigation or research which is going on.
Some examples of a sample study include:
Simple random sampling. Systematic sampling. Stratified sampling, etcPlease note that your question is incomplete so i gave you a general overview which would help you get a better understanding of the topic.

The image below shows part of the surface of a leaf.
0.1 mm x 0.1 mm
The length and width of this piece of leaf surface are both 0.1 mm
Calculate the number of stomata per mm of this leaf surface.
Explanation:
You didn't attach a picture so i'll just explain how to find the number of stomatas/mm^2.
first you find the surface by multiplying the length by the width
0.1*0.1=0.01mm^2
now you count the numer of stomatas in the picture
in0.01mm^2 you have.........................x stomatas
in 1mm you have ...............................y stomatas
y=100x

if the egg of a particular butterfly has 14 chromosomes, how many chromosomes will be found in a somatic cell for this butterfly - PLEASE HELP DUE TONIGHT
Answer:
not
Explanation:
If the egg of a particular butterfly has 14 chromosome, then the somatic cells will have same 14 chromosomes.
What are somatic cells?A somatic cell, also known as a vegetal cell, is any biological cell other than a gamete, germ cell, gametocyte, or undifferentiated stem cell that forms the body of a multicellular organism.
These cells make up the body of an organism and divide via binary fission and mitotic division.
Mitosis is a cell division process that produces somatic cells. They have two copies of each chromosome, one from the mother and one from the father. Diploid cells usually have two copies each of each chromosome.
Mitosis is the method by which one cell splits into two genetically identical daughter cells.
The cell's chromosomes are copied and then distributed evenly between the two new nuclei of the daughter cells during the various stages of mitosis.
Thus, as these are somatic cells, they will have same number of chromosomes.

Which type of reproduction is responsible for genetic variation?
Answer:
sexual reproduction
Explanation:
Sexual reproduction results in infinite possibilities of genetic variation. In other words, sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other.
Other reproductions like asexual, budding or fragmentation don't produce genetic variation.
The type of reproduction is responsible for genetic variation is - sexual reproduction.
Sexual reproduction is combining genetic information from two individuals, by the fusion of gametes such as sperm and egg, called fertilization which generates more genetic variation, by the process like the combination of alleles and crossing over.
Parents and offsprings are not identical in this reproduction type, however, they are genetically similar.Fusion or combination of two different parent's gametes.There is recombination take place which causes genetic variations as well.Thus, the correct answer that is responsible for genetic variation is - sexual reproduction.

Use the concept of negative feedback to explain body temperature control in humans.
Answer:
Negative feedback is a vital control mechanism for the body's homeostasis. ... When body temperature drops, the hypothalamus initiates several physiological responses to increase heat production and conserve heat: Narrowing of surface blood vessels (vasoconstriction) decreases the flow of heat to the skin.
