Answer: B.
Explanation:
Which molecules may diffuse across a cell membrane without the expenditure of energy or the use of membrane proteins?
Explanation:
In simple diffusion, small molecules without charges such as oxygen and carbon dioxide flow through a plasma membrane without assistance and without expending energy. Other substances such as proteins, glucose and charged particles called ions cannot pass through the selectively permeable membrane
what is the relationship between heart rate & respiratory rate (impact on oxygen, carbon dioxide & energy levels)
What is the substance with which an enzyme interacts?
protein
glucose
carbohydrate
substrate
Answer: substrate
Explanation:
What principle can be applied to all chemical reactions?
A) conservation of mass
B) reactants formed from products
C) energy loss theory
D) coefficient principle
what is the function of Motor Proteins
Answer:
Motor proteins propel themselves along the cytoskeleton using a mechanochemical cycle of filament binding, conformational change, filament release, conformation reversal, and filament rebinding.

Predict what would happen to the wolf and elk populations if there was a drought that caused many of the plant species to dry up and/or die.
Answer:the elk would die because there would be no plants left and then the wolf would die to because there would be no more elk
Explanation:
If a drought were to cause many plant species to dry up and die, it would have indirect effects on the populations of wolves and elks, which are interconnected through a predator-prey relationship.
The drought leads to a scarcity of water, which affects plant growth. Many plant species, including grasses and shrubs that serve as food sources for elks, dry up and die due to the lack of water.
With the decline in plant food sources, the elk population would face food scarcity. The reduced availability of vegetation would result in limited feeding opportunities for elks, potentially leading to malnutrition and weakened individuals.
Therefore, it's important to note that the specific outcome may vary based on the severity and duration of the drought, the overall ecosystem resilience, and the presence of alternative food sources or migration possibilities for elk and wolf populations.

3. How does ATP provide energy to your body?
Answer:
ATP(or Adenosine Triphosphate) provides energy to your body because it is a chemical that takes energy from the food you eat and turns it into energy your body can absorb. So because of this, it is considered a source of energy.

Q: What is a controlled variable? Give an example
(BTW if u can let me know if the answer is from google so I can put it in my own words, if it's not also let me know! if you don't it's fine! , works either way!)
Answer:
A control variable is the variable in the experiment that does not change.
Explanation:
If you are testing how seeds grow in different types of water, and you add 1tbps of salt to one pot of water with the plant, and then added 2tbps to another pot of water with the plant. The control variable in this experiment would be the water with no salt because it was not altered.
FYI I did not pull from google. Good luck!

Why is the series of reactions in the Calvin cycle called a
"cycle”?
Answer:
You can think of the Calvin cycle as being somewhat like a sugar factory within a chloroplast. It is called a cycle because, like the Krebs cycle in cellular respiration, the starting material is regenerated each time the process occurs. In this case, the starting material that gets regenerated is a compound called RuBP, a sugar with five carbons.
With each turn of the Calvin cycle, there are chemical inputs and outputs. The inputs are carbon dioxide from the air and the ATP and NADPH produced by the light reactions. The Calvin cycle uses carbon from the carbon dioxide, energy from the ATP, and high-energy electrons and hydrogen ions from the NADPH. The cycle's output is an energy-rich sugar molecule. That sugar is not yet glucose, but a smaller sugar named G3P. The plant cell uses G3P as the raw material to make glucose and other organic molecules it needs.
Explanation:
You can follow the process of the Calvin cycle in the figure.
The series of reactions in the Calvin cycle are called a cycle because it involves inputs and outputs.
The Calvin cycle simply refers to the process that algae and plants use in turning carbon dioxide into sugar. The Carbon cycle is made up of steps such as Carbon fixation, reduction phase, carbohydrates formation, and the regeneration phase.
The series of reactions in the Calvin cycle are called a cycle because it involves inputs and outputs. The input molecules are ATP, carbon dioxide, and NADPH. On the other hand, the output molecules are ADP, sugar, and NADP.

Questions:
A. Is the suspect guilty of the crime?
B. How do you know?
Answer:
A. No
B. because, the suspect doesn't add up to any of the DNA of the killer, victim, or the control, so no the suspect is definetly not guilty and is definetly not the killer. It just wouldn't add up right, none of the other's DNA matches to the suspect, leaving the suspect as not guilty but inisent and doesn't lead or match that suspect to in any way the killer. In other words the killer and suspect don't link in any way!
