why are the models of solar systems that you can purchase in stores not to scale?
Answer:
If they were to scale, it wouldn't fit on Earth since a lot of planets are much bigger than Earth
As the solar systems are around 287 billion kilometers across, the models of a solar system we can buy in stores are not accurate to size.
What is Solar system?The Sun and the asteroids that orbit it make up the gravitationally bound system is known as the Solar System. A massive interstellar molecular cloud gravitationally collapsed to make it 4.6 billion years ago. The Sun contains the great majority of the remaining mass, with Jupiter holding the lion's share of the remaining mass.
The Sun and the things that orbit it make up the Solar System. The Sun, our star, and everything gravitationally attracted to it, including planets like Earth, asteroids, meteors, comets, and many other objects, make up our solar system.
Thus, as the solar systems are around 287 billion kilometers across, the models of a solar system we can buy in stores are not accurate to size.

Cells in the nervous system have a potential difference of 70mV across the cell membrane separating the interior of the cell from the extracellular fluid. This potential difference is maintained by the iion pumps that move charged ions across the membrane. Is this an emf
Answer:
The correct answer is - yes, The ion pumps can actively separate charge; thus, they can create a potential difference.
Explanation:
Ion channels create a potential difference by providing a path for the flow of current across the membrane. Ion pumps such as Na+/K+ pump create a potential difference across the membrane by separating the charge.
In the sodium-potassium pump the movement of ions across the inside and outside of the membrane by active transport. The concentration difference between the inside of the membrane and outside of the membrane causes a potential difference.

A student wanted to test the effectiveness of a new type of drug that would partially block Ca2 channels on the sarcoplasmic reticulum. She had a population of 15 frogs and divided them into three groups: 5 frogs received 50mg of the drug, 5 frogs received 25mg of the drug and 5 frogs received a placebo. She isolated a muscle from each frog and measured how much force it exerted during a contraction. She also recorded the air temperature in laboratory because temperature could affect muscle proteins. What was her dependent variable
Answer:
This question is incomplete as it lacks options, the options are:
A. drug dose
B. type of drug
C. force of contraction
D. air temperature
The answer is C. Force of contraction
Explanation:
In an experiment, the DEPENDENT VARIABLE (effect) is the variable that responds to the changes made to the independent variable (cause). It is the variable that is measured as the independent variable is being manipulated in the experiment.
In this case, a student wanted to test the effectiveness of a new type of drug that would partially block Ca2 channels on the sarcoplasmic reticulum. She used a total of 15 frogs, which were divided into three groups and administered different doses of the drug (independent variable). However, the AMOUNT OF FORCE A MUSCLE EXERTED DURING CONTRACTION was measured. Hence, the dependent variable is the force of contraction of the muscle.

In summary, transgenic _______________ flies will produce light in a pattern that reflects the _________________________________ activity of the _______________ gene.
Answer: per-luc; transcriptional; period
Explanation: While the transgenic fly is expected to have normal transcriptional activity per gene, and a normal biological clock, however, the transgenic fly can have red eyes and per transcriptional activity can be reported as light emissions. Transcription of the transgene results in production of the enzyme luciferase, which acts on luciferin substrate. Therefore, in summary, transgenic per-luc flies will produce light in a pattern that reflects the transcriptional activity of the period gene.

1. Why do you have a dedicated circulation pathway for the spleen, stomach, pancreas, gallbladder, and intestines that passes through the liver
Answer:
Because the liver is a crucial organ that processes the nutrients that the blood carries. Also, we storage blood when the volume of it is above the normal levels.
Explanation:
The blood that circulates through the spleen, stomach, pancreas, gallbladder, and intestines has to pass through the liver. This organ will metabolize proteins, lipids, cholesterol, bilirubin, toxins, and steroid hormones, also store glycogen, fats, Ferrum, and vitamins, and produce bile. The nutrients that the blood carries are processed in the liver to keep the body healthy and to eliminate substances through bile. The bile will also help with the digestion of nutrients in the intestine.
When the blood from these organs (spleen, stomach, pancreas, gallbladder, and intestines) goes to the liver via the hepatic vein, the hepatic cells process it and deals with the functions previously mentioned. Once that blood is filtered, it goes to the hepatic veins, and from there, to the heart.
The liver and Spleen are the two primary organs of the body, through which blood circulates and purifies. The organs like the gall bladder, spleen, liver, and pancreas are involved in the circulation of blood.
The blood circulated between the organs like the spleen, stomach, intestine, and pancreas is sent to the liver.
The liver plays a crucial role in the metabolism of toxins, bilirubin, proteins, lipids, and cholesterol. Also, glycogen, hormones, and vitamins are also stored in the liver.
The nutrient-rich blood is present in the blood, which helps in maintaining the health and proper functioning of the body.
The blood from these organs is delivered by the hepatic vein to the liver, and the hepatocytes metabolize the nutrients. The blood once filtered and purified, is delivered to the heart via hepatic veins.
Thus, the blood circulation between the liver and other organs like the spleen and gall bladder is necessary to metabolize nutrients before sending them to the heart.
