2. Explain why glucose continues to enter a cell, even when the concentration inside the cell might be higher than outside.
Answer:
Both diffusion and facilitated diffusion are driven by the potential energy differences of a concentration gradient. Glucose enters most cells by facilitated diffusion. ... Na+ is maintained at low concentrations inside the cell and K+ is at higher concentrations. The reverse is the case on the outside of the cell
Glucose continues to enter a cell, even when the concentration inside the
cell might be higher than outside as a result of the process known as active
transport.
Active transport involves the movement of molecules through a
cell membrane against the concentration gradient. Examples include:
Antiport Pumps.Symport Pumps.This type of transport requires the use of energy such as ATP to move the
glucose molecules into the cell.

Why is the surface temperature of the ocean usually greater than the temperature on the ocean floor?
Answer:
Cold, salty water is dense and sinks to the bottom of the ocean while warm water is less dense and remains on the surface.
Cold water is a higher density in warm water.
The actual amount of heat generated per square meter of earth is quite small, especially compared to the amount of heat necessary to warm the ocean.

Thyroid hormone receptor (TR) regulates growth, development, and differentiation of mammals. TR contains both a domain that binds to T3, the thyroid hormone, and a separate domain that binds to DNA. Which of the following BEST explains how TR signals?
A. T3 binds to TR at the cell membrane, which then releases second messengers to regulate gene expression.
B. T3 binds to DNA at the cell membrane, which then releases second messengers to regulate gene expression.
C. T3 diffuses through the cell membrane to bind to TR, which then binds to DNA to regulate gene expression.
D. T3 diffuses through the cell membrane to bind to DNA, which then binds to TR to regulate gene expression.
Answer:
C. T3 diffuses across the cell membrane, attaches to Tr, and then binds to DNA to control gene expression.
Explanation: Thyroid hormone, as a ligand, diffuses across the plasma membrane, then searches for the nucleus TR (Thyroid receptor and RxR aie heterochimeric bind to DNA).
When Thyroid Hormone binds to the A domain of T3, Corepressor Proteins are removed, which stimulates gene transcription.

Explanation:
How does the friction affect the total time a pendulum is in motion? And what could cause this friction in the real world?
Answer:
Without friction, the equation of motion for a pendulum of length L is,
md2θdt2+mgsin(θ)L=0.
Or for small oscillations, (i.e., sin(θ)≈θ),
md2θdt2+mgθL=0.
Assuming an initial angle θ0 and a pendulum that starts at rest, the solution to this differential equation is,
θ(t)=θ0cos(gL−−√t).
Frictional force adds an additional damping term into the equation of motion,
md2θdt2+λdθdt+mgθL=0,
where λ is a coefficient of kinetic friction.
Assuming an initial angle θ0 and a pendulum that starts at rest, the solution to the damped differential equation is,
θ(t)=θ0e−12λmtcos((gL−λ24m2−−−−−−−−√)t).
(Note: If you would like to consider closed form solutions for large angles, I would recommend consulting the mathematics section. The solutions to that problem are called elliptic integrals of the first kind.)
Friction decreases the total time that a pendulum is in motion.
If we consider a pendulum in motion, in accordance with Newton's law, the pendulum will continue moving unless it is acted upon by an external force.
In the case of the pendulum, the external force that acts on it is the air resistance or friction. As a result of this friction, the pendulum will eventually come to a stop.
In the real world, the surface of objects cause friction which causes moving objects to stop.

A hormone signals through a G protein-coupled receptor as shown in the diagram. After the production of IP3, which of these events will MOST quickly stop the transduction of the signal?
A. the hydrolysis of IP3
B. the hydrolysis of GTP
C. the hydrolysis of PIP2
D. the hydrolysis of the hormone
Answer: The answer is A
Explanation: Took the test lol
The quickest halt to the signal transduction process after IP3 production occurs through the hydrolysis of IP3 itself, as option A.
The hydrolysis of IP3 results in the quickest termination of the signal transduction pathway among the available alternatives. A series of actions are triggered by IP3, which causes the release of calcium ions from intracellular reserves. IP3 is hydrolyzed by phosphatases, which halts the calcium release and prevents protracted signaling.
Even while the hydrolysis of GTP and PIP2 is a necessary step in the cessation of G protein-coupled receptor signaling, it happens later and does not have the same rapid effects as IP3 hydrolysis. The hormone's own breakdown is not a known mechanism for halting signal transmission.

Where in a cell would you most likely find DNA?
Your answer is → compartment within the cell called a nucleus
In a cell, DNA would most likely be found inside the nucleus which is known as the controlling center of the cell.
What is DNA?DNA stands for Deoxyribonucleic acid. It is considered the most common genetic material of living organisms. The genetic information of a particular organism is encoded with these segments, known as DNA.
The process of transcription is initiated within the nucleus of the cell which transforms DNA into mRNA. It is known as the brain of the cell. Due to compartmentalization in eukaryotic organisms, a well-defined nucleus has appeared which helps in the transfer of genetic information from one generation to the next.
Therefore, the nucleus is the region where DNA is most likely found within the cell.

Which of the following best describes sickle-cell anemia?
O Caused by environmental factors that an individual was exposed to during pregnancy.
O A hereditary genetic mutation that causes a resistance to malaria.
O An inherited disorder that increases the risk of contracting malaria from mosquitos.
O A genetic mutation that is inherited from a dominant allele of one parent.
Answer: The answer should be B "O A hereditary genetic mutation that causes a resistance to malaria."
Explanation:
I do FLVS also you can find this out in your lesson 3.04 on page 5.
It says, "Sickle-cell disease is a genetic disorder that gives red blood cells a crescent shape instead of the typical disk shape. Sickle cells are stiff and sticky. They tend to block blood flow in the blood vessels of the limbs and organs. Blocked blood flow can cause pain, serious infections, and organ damage. This genetic disease is recessive, meaning the allele must be inherited from both parents to be expressed in a person’s phenotype. It is caused by a mutation in the gene that produces hemoglobin, the blood’s principle oxygen-carrying protein. Sickle-cell disease occurs more commonly in people and descendants from tropical and subtropical regions where malaria is common. Scientists have discovered that individuals with just one allele for sickle-cell disease are not only healthy, but they actually have a high resistance for the parasite that causes malaria. This resistance gives the carriers of one sickle-cell allele a great advantage over malaria, which claims more than a million lives each year, and explains why the allele for this dangerous genetic disease survives to be passed down to future generations."

The sickle cell gene is inherited and results in sickle cell disease. You cannot catch HPV from an infected person because it is not brought on by whatever the parents did either before or during the pregnancy. Thus, option B is correct.
What are the characteristics of sickle-cell anemia?Red blood cells are typically disc-shaped and sufficiently flexible to pass readily through blood arteries.
Red blood cells with sickle cell disease have a crescent or “sickle” shape. Because sickle cells impede blood flow to particular organs, sickle cell disease complications can develop.
The severe side effects include stroke, acute chest syndrome, organ damage, various disabilities, and even early death. Acute chest syndrome lowers the blood's oxygen content.
Therefore, A hereditary genetic mutation that causes a resistance to malaria.

Every year, 25 km 3 of sand is deposited on a beach by a nearby river, and 28 km 3 of sand is removed by wave action. Is the size of the beach increasing or decreasing? Explain your answer.
If 25 km3 of sand is deposited on a beach yearly and 28 km3 of sand is removed by wave action, the size of the beach would be decreasing, not increase.
First, there is a need to understand that the size of a beach is a function of the amount of sand deposited into it. The more the sand deposited, the more the beach would increase in size.
In this case, 25 km3 of sand is deposited annually but 28 km3 of sand is washed away by waves. The net amount of sand deposited can be calculated by subtracting the amount washed away by waves from the amount deposited. Thus
Net sand deposited = 25 - 28
= -3 km3
Hence, the net amount of sand deposited annually is negative, meaning that the beach would decrease in size.

What are some explained examples of pathways on how cells obtain energy.
Answer:
Catabolic pathways release the energy stored in complex molecules through the breakdown of these molecules into simpler compounds. Anabolic pathways, sometimes called biosynthetic pathways, require energy to combine simpler molecules into more complicated ones.
Exergonic reaction proceeds with a net release of free energy and is spontaneous. Endergonic reactions are nonspontaneous; they must absorb free energy from the surroundings.
Enzymes are biological catalysts agents that speed the rate of a reaction but are unchanged by the reaction
Investment of activation energy is known as a free energy of activation where the energy that must be absorbed by reactants to reach the unstable transition state, in which bonds are likely to break, and form which the reaction can proceed.
