Microscopes use lenses to magnify objects. A simple microscope uses only one lens; a magnifying glass could be called a simple microscope. The magnification of a simple microscope doesn't need any calculation because the single lens is usually labeled. A hand-lens, for example, might be labeled with 10x, meaning the lens magnifies the object to look ten times larger than the actual size.
Explain the relationship between the number of whales, the number of plankton (Biomass), and the amount of CO2 (Carbon Dioxide) in the atmosphere.
Answers
Answer:
Plankton are producers therefore they use the CO2 in the atmosphere and convert it to oxygen. Whales eat the plankton while sometimes using the oxygen that the plankton produces. In this situation, the whale is a primary consumer, or a heterotroph, as the plankton is the producer, or autotroph. Hope this helped :D

What is the ABO blood classification based on?
antibody on the red blood cell
antigen in the blood
antigen on the red blood cell
hemoglobin in the blood
Answers
The ABO blood classification is based on antigen on the red blood cell. Therefore, option (C) is correct.
What do you mean ABO blood classification?Based on the presence or absence of antibodies and antigenic substances on the surface of red blood cells, a blood type is a classification of blood.
A framework used to human blood into various kinds, in view of the presence of specific on the outer layer of platelets. A, B, O, and AB are the four blood ABO types.
When there are more than two possible alleles for a single chromosomal locus, this is called a multiple allele. The ABO blood bunch is an exemplary illustration of this. Each person has two alleles for the ABO blood type because they have two number 9 chromosomes.

Why are the properties of a compound so different than the properties of the elements that make up the atom?
Answers
Answer:
The properties of compounds are different from the properties of the elements that form them—sometimes very different. That's because elements in a compound combine and become an entirely different substance with its own unique properties. Do you put salt on your food? Table salt is the compound sodium chloride.

Copper sulfide is found written as both CuS and Cu2S. Why are there two forms for writing this chemical formula?
SELECT AN ANSWER
This is an example of a combination reaction: CuS is the halfway stage, before the second copped atom joins the molecule.
Copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+).
This is a synthesis reaction and so the formula will continue changing until all the atoms have conglomerated.
One of the versions is a mistake, the correct form should be Cu2S.
Answers
Answer:
option 3
Explanation:
Copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+).
There are two forms for writing the chemical formula because copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+)
Copper is a transition metal with variable oxidation states. The oxidation states of copper is what determines the name of CuS and Cu₂S.
Now, we shall determine the oxidation states of copper in each compound.
For CuS:
CuS = 0
S = –2
Cu =?Cu + S = 0
Cu + (–2) = 0
Cu – 2 = 0
Collect like terms
Cu = 0 + 2
Cu = +2For Cu₂S:
Cu₂S = 0
S = –2
Cu =?2Cu + S = 0
2Cu + (–2) = 0
2Cu – 2 = 0
Collect like terms
2Cu = 0 + 2
Divide both side by 2
Cu = 2/2
Cu = +1From the calculations made above, we can see that copper has oxidation state of +2 in CuS and +1 in Cu₂S
Thus, we can conclude that Copper is a transition metal with two possible ionic states and this accounts for the different names of CuS and Cu₂S

You find and collect several wild plants from around campus and decide to perform some experiments to determine the relationship between the purple and yellow gene traits. You either perform self-crosses (selfing) or you carefully perform cross-pollination experiments between two plants and obtain the following results:
Pollination Purple Progeny Yellow Progeny
Purple (self) 87 0
Purple (self) 76 24
Yellow (self) 0 95

If the endoplasmic reticulum were removed from the cell, which organelle would not be able to function properly, and why? mitochondria, because they rely on the ER as an energy source ribosomes, because they receive proteins made by the ER Golgi apparatus, because it packages proteins received from the ER cytoplasm, because it relies on the ER for structural support
Answers
Answer:
Golgi apparatus, because it packages proteins received from the ER
Explanation:
The function of the endoplasmic reticulum is to produce proteins. It can be smooth or rough. The rough endoplasmic reticulum has ribosomes, which make the proteins.
The Golgi apparatus receives proteins from the endoplasmic reticulum and modifies and sorts them. They are then concentrated and packed into vesicles which are released out of the cell membrane.
If the endoplasmic reticulum is removed, proteins cannot be made and the Golgi apparatus would not be able to perform its job.
Hope that helps.

Which statement describes a disruption that can occur in the cell cycle, leading to the development of
cancer?
A. A virus interferes with checkpoints within the cell cycle, resulting in slower cell proliferation.
B. A virus interferes with checkpoints within the cell cycle, resulting in uncontrolled cell apoptosis.
c. A gene mutation interferes with cell cycle control mechanisms, resulting in uncontrolled cell
proliferation.
D. A gene mutation interferes with cell cycle control mechanisms, resulting in an increased rate of cell
apoptosis.
Answers
Answer:
The correct answer is - option C. A gene mutation interferes with cell cycle control mechanisms, resulting in uncontrolled cell proliferation.
Explanation:
Genetic mutations resulting in the change or absence of any regulatory proteins that used during checkpoints can result in the mechanism of turning on or turning off the cell cycle or allow a cell to move further for the division. Due to this change, the checkpoints are not able to prevent it from division.
Uncontrolled multiplication or proliferation of the cell, resulting in tumor development or cancer.
