One of the primary advantages of cell culture is the ability to isolate a single type of cell from a multicellular organism. How has this advance changed the study of biology?
Single-type cultures are easier and cheaper to maintain than cultures made of mixed cell types.
Scientists can completely avoid using animal or human test subjects during their experiments.
Cultures with single cell types behave in culture exactly as they would behave in a tissue or organ.
Scientists know that any response during an experiment is associated only with that cell type.

Erosion typically wears the Hawaiian volcano Mono Loa down about 20 cm in 5 years. Lava flows build the volcano up about 10 cm every time there is an eruption. Mono Loa erupts about once every 2 years. Is the volcano growing or wearing down?
Answer: The Volcano is growing little by little
Explanation:
it goes down 4cm every year so in 2 years it will have gone down by 8cm then it erupts and goes up by 10cm gaining back to 8cm it lost, plus the extra 2cm.

Explanation:
Anjuli performed an experiment to determine the respiration rate of yeast. She determined this by measuring the amount of carbon dioxide (CO2) that was produced. Then, she created the following graph.
She should redraw her graph as a line graph because she was measuring a rate of change and is therefore denoted as option B.
What is Graph?This is referred to as a pictorial representation of data or variable in an organized or definite manner.
A line graph is a type of graph comprises of points which are usually connected by a straight line and it is used to show how different types of variables change over a given period of time. The slope of the line graph provides information about the rate involved.
Anjuli was told to redraw her graph as a line graph because the rate of respiration of yeast is what is to be determined and will provide sufficient information about it which is therefore the reason why option B was chosen as the most appropriate choice.

You are examining two primary options and their trade-offs before making a decision at the margin.
The margin represents the activity's current level. Consider it as the vantage point from which to make a decision. A decision to do something a little bit more or a little bit less is referred to as a margin choice. Making decisions at the margin can reveal very insightful information. Virtually almost all choices, are made at the margin. Individuals do not make choices about whether they should or should not consume something or not. Rather, they decide whether to consume a little more or a little less of it.

Answer: Option C should be the best answer
Explanation: If you look at option A it can be ruled out because when population 1 temp, on the graph, changes from 15C to 20C there is a decline according to the arch.
Option B is similar in that population 1 continues to decrease on it's arch with temps from 20C to 25C.
Option C is not incorrect, as population 1 arch has a pinnacle of 15C and population 2 has a pinnacle of 25C respectively.
Option D can also be ruled out because neither populations reach those numbers for their arched graphs.

Which equation shows how cells use the energy stored in an energy carrier?
A. ADP + H+ → ATP
B. NADPH →NADP+ + H+
C. NADP+ + P→ ATP
D. ATP → ADP + NADPH
The equation that shows how cells use the energy stored in an energy carrier is as follows: ATP → ADP + NADPH (option D).
How is energy used in the cell?Energy is the capacity to do work and a very important criterion for every metabolic activity that occurs in living cells.
The energy currency in the cells of living organisms is Adenosine triphosphate (ATP). ATP is a biomolecule that is used as a source of energy in cellular reactions.
Energy is stored in the cell when a phosphate group is added to ADP while the energy is dispensed for use when phosphate group is lost from ATP to become ADP.
This means that the equation that portrays how cells use the energy stored in an energy carrier is as follows: ATP → ADP + NADPH.

Question 1 of 5
Prove: If two angles are supplementary, then one of the
angles must be obtuse.
Which image provides a counterexample to this
statement?
If two angles are supplementary then one of it must be obtuse. Because supplementary angles are those two angles whose sum is 180. If either of the two is acute then the other must be obtuse to satisfy the condition.
When two angles formed on a line and they adjacent to each other, then their sum is equal to 180°. Such two angles are called supplementary angles.
In the figure A,
Two angles are drawn, one of 40° and another of 140°. Sum of these two angles are 180°, so these two angles are supplementary.
Now, for any general case,
Let us assume that an acute angle of x° is is drawn on a line. Let the adjacent angle on that y° angle will,
x° + y° = 180°
y° = 180° - x°
the value of x can take place between,
0° < x° < 90°
So,
y° = 180°-x°
Y becomes,
90° < y° ≤ 180°
Hence Y is an obtuse angle.
It is proved that If two angles are supplementary, then one of the
angles must be obtuse.
There is no counterexample to this statement except the case referred in Image B.

4. Critical Thinking How would Mendel's observations and conclusions have been different if
many of the characteristics he studied, such as seed color and seed texture, had been controlled
by genes located close together on the same chromosome?
If following that would have happened in Mendel's observations and conclusions then there wouldn't be independent assortment.
What was Mendel's original experiment?Mendel started out by testing out a single pea plant trait at a time. He began with the hue of flowers. Mendel crossed-pollinated parent plants with purple and white flowers, as seen in the illustration below. The P (for parent)generation in the experiments stands for the parent plants. Mendel proposed three laws of inheritance, which are as follows.
The segregation of the two alleles of a particular gene into the gametes is described by Mendel's first law.In a heterozygote, one trait will mask the presence of another trait for the same characteristic, according to Mendel's law of dominance.According to Mendel's law of independent assortment, the alleles of two or more distinct genes are independently sorted into gametes.To know more about heterozygous :
