PLEASE I NEED THIS ASAP If you had a cell that was cube-shaped with a side length of 20µm, calculate the surface to volume ratio of the cell. Round your answer to the tenths place.
Answer:
Ratio = [tex]3\times 10^5[/tex]
Explanation:
Side of a cube, a = 20 µm
[tex]a=20\times 10^{-6}\ m[/tex]
The surface area of a cube, A = 6a² (a is side of the cube)
The volume of a cube, V = a³
The ratio of the surface to volume ratio of the cell will be given by :
[tex]R=\dfrac{6a^2}{a^3}\\\\R=\dfrac{6}{a}\\\\R=\dfrac{6}{20\times 10^{-6}}\\\\R=3\times 10^5[/tex]
So, the ratio of the surface to volume ratio of the cell [tex]3\times 10^5[/tex].

There's a block of metal with the dimensions below that weighs 2500 grams. What is the density of
the metal?
The correct answer is 37.72 g/[tex]cm^{3}[/tex]
Explanation:
To find the density of this block the first step is to find the total volume or space occupied by the block. This is because the volume is one of the factors that determines density (Density = mass ÷ volume). Now, to find the volume multiply the three sides given or the length, width, and heigh:
6 cm × 3 cm × 4 cm = 72 [tex]cm^{3}[/tex]
Finally, calculate the density:
2500 grams ÷ 72 cubic centimeters = 37.72 g/[tex]cm^{3}[/tex]
Suppose a volcano sent large amounts of ash into the air that blocked the sunlight over a large area of ocean water for several months. Would this affect life in the ocean? Explain why or why not.
Answer:
Explanation:
Certain types of volcanic ash do not dissolve easily in water. Instead, they clump on the surface of the ocean in pumice rafts. These rafts can clog salt water intake strainers very quickly, which can result in overheating of shipboard machinery dependent on sea water service cooling.

Two examples of enzymes and their pH in the environment in which it works are pepsin whose pH is 2 and Lipase whose pH is 8.
What are enzymes?Enzymes are biocatalysts made up of proteins to increase the speed of the reaction.
Enzymes do not involve in the reaction and in the end of the reaction they separate from the reaction and their substance is specific. They are specific to reactions whose speed is increased by these enzymes in high temperatures and pH their structure changed as they are protein and with extreme where they also get the nature.
The two enzymes are pepsin works best in strongly acidic environments and lipase works best in a basic environment.
Therefore, Pepsin, an enzyme with a pH of 2, and lipase, an enzyme with a pH of 8, are two examples of enzymes and the environments in which they function.

Fermentation and aerobic respiration break down glucose to make
energy. Which statement correctly compares the two processes?
Fermentation uses more oxygen than aerobic respiration uses.
A.
B.
Aerobic respiration uses more glucose than fermentation uses.
C.
Aerobic respiration produces less energy than fermentation

D.
Fermentation produces less energy than aerobic respiration
produces.
Answer: Fermentation produces less energy than aerobic respiration produces.
Explanation:
Just took the quiz
Fermentation has been the process that occurs in the bacteria and yeasts to break sugar in absence of oxygen. It produces less amount of energy than the process of aerobic respiration. Thus, option D is correct.
What are fermentation and aerobic respiration?Fermentation has been the process of producing energy by the chemical breakdown of the carbohydrates molecule by the enzymes in absence of oxygen molecules in yeasts, bacteria, etc. The end products also produced carbon dioxide gas as an effervescence.
On the other hand, aerobic respiration has been one of the processes of cellular respiration that uses oxygen to break the carbohydrate molecules into energy in the form of ATP. This type of respiration is the most common and occurs in the majority of organisms.
Both processes use carbohydrate molecules to produce energy, adenosine triphosphate (ATP) at the end of the reaction. Aerobic respiration is metabolic and fermentation has been the catabolic process. The amount of energy produced in fermentation is relatively less compared to aerobic due to incomplete oxidation of glucose.
Therefore, in option D. the amount of energy differs in both processes.

A proteinâs function is determined by the properties of its amino acids. Which replacement of one amino acid with another is least likely to affect the proteinâs function?
a. A hydrophilic amino acid is replaced by a hydrophobic amino acid. an amino acid with a C=O group is replaced by an amino acid with an O-H group.
b. A charged amino acid is replaced by an amino acid with a side chain consisting of a group with three C-H bonds.
c. A hydrophobic amino acid is replaced by a charged amino acid.
b. A negatively charged amino acid is replaced by a positively charged amino acid.
Answer:
an amino acid with a C=O group is replaced by an amino acid with an O-H group
Explanation:
When an amino acid is substituted by another with opposite properties the replacement will modify the structure (and consequently also the function) of the resulting protein. For example, it is expected that the replacement of amino-acid residues with different solubility will alter the protein’s structure and this protein will establish different interactions with water, cell structures, or further segments of the protein. Therefore, in the cases above enumerated, only C-O and O-H groups have similar properties (i.e. they are hydrophilic and have polar bonds), and thereby it is expected that this replacement has no significant incidence on the protein’s structure and function.
If less dense crust collides with less dense
crust, then this must be an example of
A. continental crust to continental crust collision..
B. continental crust to oceanic crust collision.
C, oceanic crust to oceanic crust collision.
D, a subduction zone.
The subduction zone is the area where a less dense plate collides with a denser plate, causing the subduction of this last one. The correct option is D. a subduction zone
What is a subduction zone?
The term subduction refers to the sinking process of one plate under another plate after a collision event.
Subduction zones are the areas in which plates approximate, collide, and one of them must subduct under the other one.
The plate that subduces is always the denser and older one. The less-dense plate superpose over the denser one and push it down toward the mantle. At this point, rocky material from the subductive plate melt again.

2. What is exponential growth? When does it occur?
Answer:
Exponential growth is a pattern of data that shows greater increases as time goes on. you can recognize exponential growth when there is a curve of an exponential function. If a population of mice doubles every year starting with two in the first year, the population would be four in the second year, 16 in the third year, 256 in the fourth year, and would keep rising. The population is growing to the power of 2 each year in this case which means exponentially. It occurs when a pattern of data shows high increases over time

Explanation:
Which of the following does not occur during anaphase?
A. Centromeres divide
B. Chromosomes move toward opposite poles
C. Spindle fibers pull on the chromosomes
D. Nuclear envelope dissolves
Answer:
D. nuclear envelope dissolves
Explanation:
this happens in prophase
Anaphase is a part of meiosis. In anaphase, the nuclear envelope does not dissolve. In this phase, centromeres divide, spindle fibers pull on the chromosomes, and the chromosomes move toward opposite poles. Hence, opton D is true.
What is anaphase?
Anaphase is a part of both meiosis and mitosis in the cell division process. In mitosis, the anaphase separates the daughter chromatids of the homologous chromosome by pulling them via their centromeres to the opposite poles. In meiosis, there are two stages of anaphases, such as anaphase I and anaphase II, and in each stage there are different types of chromosome separation.
In meiosis I, in anaphase I, each chromosome of the homologous chromosome is attached with a spindle fiber, but this phase only separates the homologous chromosome. The further separation of sister chromatids takes place in meiosis II, with each cell getting a haploid set.
Hence, in anaphase, the nuclear envelope does not dissolve, as this takes place in prophase. The last option is true.
