Explanation:
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].

Summarize the video.
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.

Which best describes how the photosystems are used in the light-dependent reactions?
photosystem I is used first then photosystem II
photosystem II is used first then photosystem I
Both processes are used at the same time.
Both processes are used during the light-independent reactions.
Answer:
B. photosystem II is used first then photosystem I
Photosynthesis is a series of metabolic reactions that convert sunlight, water and CO2 into sugar and oxygen. The reactions in photosynthesis can be divided into light-dependent and light-independent reactions.
The statement "photosystem II is used first then photosystem I" BEST describes how the photosystems are used in light-dependent reactions.Photosystem I (PSI) and photosystem (PSII) are protein complexes localized in the thylakoid membrane of the chloroplast.During light-dependent reactions, energy from sunlight is absorbed by chlorophyll of the photosystems. Subsequently, this energy is then converted into chemical energy (ATP and NADPH), a process that involves the transference of electrons.Both photosystem I and photosystem II contain pigments to collect sunlight energy and a reaction center in which excited electrons can be transferred from chlorophyll to an electron acceptor.Photosystem II is upstream in the electron flow pathway, but this photosystem (PSII) was discovered after photosystem I.Subsequently, electron flow is coupled to the generation of an electrochemical proton (H+) gradient across the thylakoid membrane, which is used to synthesize ATP by an ATP synthetase.In conclusion, the statement "photosystem II is used first then photosystem I" BEST describes how the photosystems are used in light-dependent reactions.

D: Geothermal
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

Which of these is dictated by the law of supply and demand?
1) oil
2) renewable resources
3) biodegradable resources
4) air pollution
The law of the supply depends on the demand and need of the resource in the market for various uses. Oil (non-renewable) is dictated by the law of supply and demand. Thus, option 1 is correct.
What are non-renewable resources?Non-renewable resources are limited resources that are not easily replenishable as it takes a very long time for them to be produced. Oil is a fossil fuel and a non-renewable resource that has limited supply and follows the demand.
Renewable resources like wind, water, soil, etc., are infinite in number and hence they are not balanced by demand and supply. On the other hand, air pollution has no demand and biodegradable resources do not dictate the demand-supply law.
Therefore, option 1. oil being a non-renewable resource is dictated by the law of supply and demand.

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.
