Explanation:
Aldosterone is a hormone secreted by the adrenal gland that activates the receptor protein to turn on genes that control water and sodium flow in kidney cells. The kidney cells contain receptor cells
with mutations. How will this impact the cellular response?
A. The aldosterone signaling molecule will also become mutated.
B. The aldosterone signaling molecule will conform to bind to the receptor cells.
C.The downstream components will be altered and ultimately affect blood volume.
D. The downstream components will function as usual, even if the receptor protein is not activated.
Pls help soon!!
Answer:
The correct option is C
Explanation:
Since the receptor cells is mutated, the adrenal gland might (depending on the type of mutation) no longer be able to activate the receptor protein which will affect water and sodium flow in the kidney cells. Thus, the flow of the downstream components (water and sodium) will be altered in the kidney which will ultimately affect the blood's volume.

Explanation:
A Paramecium has an internal sucrose concentration of 0.040 M, a glucose concentration of 0.035 M, and a fructose concentration of 0.0050 M. The Paramecium is placed in an aqueous solution that has solute concentrations of 0.025 M for sucrose, glucose, and fructose. Which solutes will diffuse out of the Paramecium?
a. Glucose and fructose
b.Sucrose and fructose
c.Sucrose and glucose
d. Sucrose, glucose, and fructose
Answer:
c. Sucrose and glucose
Explanation:
The paramecium is a large, single-celled microbes, surrounded by a plasma membrane. Simple diffusion occurs in cells across plasma membranes, as a form of passive transport. In diffusion, solutes move from regions of high concentration to regions of low concentration across the plasma membrane.
Here, the internal environment has higher concentrations of sucrose and glucose, but lower concentrations of fructose, thus the solutes will move along their concentration gradient, to where the concentrations are lower. In order for the fructose molecules to move out of the cell, the molecules have to move against their concentration gradient - a process requiring energy known as active transport.

Which statements describe what happens when enzymes are added to a chemical reaction?
Select all that apply.
- The chemical reaction is sped up.
- The chemical reaction is stopped.
- The activation energy is lowered.
- The enzymes are used up.
Answer:
The chemical reaction is sped up.
The activation energy is lowered.
Explanation:
When enzymes are added to a chemical reaction, they lower the activation energy needed in the reaction.
In return, that also speeds up the chemical reaction, since less energy is needed to start it.
Enzymes do not stop chemical reactions, and enzymes can also be reused, so they are not used up.
So, the first and third statements are correct.

Describe how deep oceanic currents are formed.
Answer:
Explanation:
Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.
Answer:
They are caused by: the sinking and transport of large masses of cool water giving rise to the thermoahline circulation. The earths rotation also influences them!

Explanation:
prophase, the condensation of the chromatin and the disappearance of the nucleolus
metaphase: chromosomes align in the equator of the cell before being separated into each of the two daughter cells.
anaphase: chromosomes are split and the newly-copied chromosomes are moved to opposite poles of the cell.
interphase: G1, S, G2
telophase: nucleoli reappear, and chromosomes begin to come back into the expanded chromatin that is present during interphase.

How does the ligand-gated channel for CFTR work?
Answer: Ligand-gated channels require a special “key” to unlock their doors, which usually comes in the form of a small molecule.
CFTR is a ligand-gated channel, but it’s an unusual one. Its “key” is ATP, a small molecule that plays a critical role in the storage and release of energy within cells in the body. In addition to binding the ATP, the CFTR channel must snip a phosphate group – one of three “P’s” – off the ATP molecule to function. But when, where and how often this crucial event takes place has remained obscure.
Explain why renewable energy sources like solar, wind, and geothermal power have more limitations to their use than

Page 1 Page 2 Radioactive decay involves the changing of a radioactive atom into another radioactive atom. For example, rocks and minerals may contain potassium-40 that changes into argon-40. Mass spectrometers measure the number of these atoms in a rock or mineral sample. This information and knowing the half-life of potassium-40 can help determine the age of rock layers. The half-life of potassium-40 is 1.3 billion years. The potassium-40 in rocks and minerals will decay through many half-lives until all of them change into argon-40. How many atoms will there most likely be at the third half-life of potassium-40 in this model? A model rock layer had 50 pennies (atoms of potassium-40). How old is the rock layer?

How can a ‘FIXED’ cell be used to estimate the time spent in each phase of mitosis. Explain the process you used to determine the times for each phase.
Answer:
Calculate the percentage of time spent in each phase by counting the total number of cells in each phase (total in interphase, in prophase, etc.) ... Multiply the percentage of time in each phase by the total time of the cell cycle (720 minutes) and this gives you an estimate of the time spent in each phase.

Which of the following must occur before DNA replication can take place?
Answer:
Before replication can occur, the length of the DNA double helix about to be copied must be unwound. In addition, the two strands must be separated, much like the two sides of a zipper, by breaking the weak hydrogen bonds that link the paired bases.
Explanation:
have a nice day :)
The length of the DNA double helix that is about to be duplicated must first be unwound before replication can take place.
What is DNA?Additionally, the weak hydrogen bonds between the paired bases must be broken in order to separate the two strands, much like the two sides of a zipper.
Positive sigma, which indicates the percent of supercoiled and wounded DNA, and the same negative sigma, which indicates the percent of DNA that was left unwounded in the presence of isomerase.
Denote the superhelical activity of DNA seen during replication during the absence of topoisomerase and will cause DNA to become more and more wounded and stop the replication process.
Therefore, DNA double helix that is about to be duplicated must first be unraveled before replication.

How are the equator and the prime meridian used on maps?
to provide a reference system
to separate Earth’s four hemispheres
to measure distances east and west
to identify the location of Earth’s continents
Answer:
A- to provide a reference system
Explanation:
The equator and prim meridian used on maps provides a reference system for determining location and navigating the earth.
An equator is the only line of latitude that is a great circle.
Prime meridian is a line of longitude that is 0°
When both are used, they can form the basis of a reference system to determine places on earth.
Using these lines, we can assign values of coordinates to the earth surface to facilitate location determination.
The equator and prime meridian are used on maps to provide a reference system.
The equator and the prime meridian used on maps to provide a reference system. Thus, option A is correct.
