Answer:
b. No, her cells need glucose to react with oxygen to release enough energy to exercise.
Explanation:
Living organisms are able to perform any of their day-to-day activities due to the release of energy in their individual cells. The process by which this energy is obtained by their cell is called CELLULAR RESPIRATION. Cellular respiration is the process whereby glucose (from digested food) is broken down in the presence of oxygen to yield energy in form of ATP. The general equation is as follows:
C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 + 6H2O + ATP
According to this question, a doctor is said to test a patient for the content of molecules in her cells. Her cells were found to contain normal levels of oxygen molecules, low levels of amino acid molecules, and low levels of glucose molecules. This patient will NOT BE ABLE to exercise normally because her cells need glucose in optimal amount to react with oxygen to release enough energy to exercise.
On the basis of blood type, you know that one of the children could not have been the son of the two adults. Does this prove that the other child is their son
Answer:
No.
Explanation:
No, Blood test can't tell us that the which child is the son of two adults, it can only be find out by DNA testing of children with the two adults. If the DNA testing matches of children to the adults then we can say that these children are the sons of two adults while on the other hand, if the DNA of two children not match with the two adults then we can say that they are not their child.

Answer:
False
producers make food
Explanation:
Ligand gated means controlled by the _______________ or signal molecule. If the door is closed, certain ______________are blocked from entering the cell. When the ______________or signal molecule is attached, the door is open for certain ________________to enter the cell. These types of receptors are important in the _________________.
Answer:
ligand; ions; ligand; ions; nervous system
Explanation:
Ligand-gated ion channels are transmembrane protein complexes that open when they bind to their corresponding ligands (e.g., neurotransmitters). This type of receptor is known to modulate the synaptic transmission between neuron cells or neuron and muscle cells. In the nervous system, ligand-gated ion channels located at sites of synaptic contact determine the ion flow in response to neurotransmitter binding. Some examples of ligand-gated ion channels include gamma-aminobutyric acid A (GABA-A) and nicotinic cholinergic receptors.

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.

what is the carbon cycle in the alpine tundra ecosystem. (how does carbon move)
Answer:
Tundra is one of the biggest carbon dioxide sinks on Earth. ... As a result of climate change, tundra soils are thawing deeper and deeper and for a longer periods of time in the upper layers of permafrost. This causes organic matter to decompose faster, releasing larger amounts of carbon dioxide into the atmosphere.
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.
What is copied each time a cell divides?

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.

which of the following is the correct pathway of blood through the body, including the lungs?
no troll please!!!!
The correct pathway of blood through the body, including the lungs, is heart----> aorta----> body----> vena cava----> heart----> pulmonary arteries----> lungs----> pulmonary veins----> heart.
What is blood circulation?It is the circulation of blood throughout the body.
What are the two types?The two types are:
Pulmonary circulation starts with deoxygenated blood from the right ventricle where, through pulmonary arteries, it reaches the lungs (oxygenation of blood occurs), then through pulmonary veins, blood enters the heart in the left atrium.
Systemic circulation starts with oxygenated blood from the left ventricle, from where, through the aorta, it is pumped to the body, then to the superior or inferior vena cava, and then blood reenters the heart in the right atrium.
Hence, the correct answer is option b): heart--> aorta--> body--> vena cava--> heart--> pulmonary arteries--> lungs--> pulmonary veins--> heart.

Why is it important to reduce the number of chromosomes in half when forming gametes for sexual reproduction?
a) The offspring will have the correct number of chromosomes when sperm and egg are joined.
b)Gametes have single function which requires less DNA to preform the function compared to somatic cells.
c)A reduction in the number of chromosomes reduces the chances for mutations that would affect the offspring.
d)The chromosomes in gametes are already replicated strands of DNA which returns the number of chromosomes to the original amount.
Answer:
B.
Explanation:
It is important to reduce the number of chromosomes in half when forming gametes for reproduction because offspring will have the correct number of chromosomes when sperm and egg are joined.
WHAT ARE GAMETES:Gametes are cells produced for the purpose of reproduction. Gametes are produced as a result of meiosis, which reduces the chromosome number by half. Gametes include sperm cells and egg cells, which fuse together to form zygote. The zygote develops into a new organism.Therefore, reduction is necessary in order to have the correct number of chromosomes when sperm and egg are joined.
