If a reaction in one direction releases energy, the reaction in the opposite direction ABSORB ENERGY (Option B)
All chemical reactions involve some type of transfer of energy.There are two types of chemical reactions: exothermic reactions and endothermic reactions.An exothermic reaction is a process that releases heat (i.e., releases energy), while an endothermic reaction requires an input of energy to proceed.In conclusion, if a reaction in releases energy, a reaction in opposite direction ABSORB ENERGY (Option B).

Why do you think electron microscopes allow for greater magnification than compound microscopes?
Explanation:
Electron microscopes have a greater magnifying power than optical microscopes due to the use of shorter wavelength electrons.they allow magnifications of up to one million times the size of a specimen while optical microscopes can achieve a magnification of no greater than 1000x.
I hope it's helpful!
An Electron microscope allows for greater magnification than compound microscopes it utilizes electrons of a much shorter wavelength as compared to the visible light in a compound microscope.
What is an Electron microscope?An electron microscope may be defined as a type of microscope that utilizes a beam of accelerated electrons in order to construct or produce an enlarged image of tiny objects or specimens like virus cells.
The higher resolution power is the characteristic feature of the electron microscope. An Electron microscope allows a magnification of approximately one million times the actual size of objects or biological specimens.
While, when it comes to the compound microscope, the magnification power limits to a thousand times the actual size of objects or biological specimens.
Therefore, the utilization of electrons of a much shorter wavelength is responsible for greater magnification in the electron microscope.

9. Doctors tested a patient to find out what molecules were in her cells. Her cells contained normal
levels of oxygen molecules, low levels of amino acid molecules, and low levels of glucose molecules
Will this patient be able to exercise normally?
a
Yes, as long as her cells have enough oxygen, her body will be able to exercise,
b
No, her cells need glucose to react with oxygen to release enough energy to exercise.
С
No, her cells need amino acids to react with oxygen to release enough energy to exercise.
d
No, her cells need glucose to react with amino acids to release enough energy to exercise.
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.

remember to imagine that blood in the heart is color-coded according to its oxygenation status. What color of blood would you expect to see in isabelle's left ventricle
Answer:
Red blood.
Explanation:
Red blood is for oxygenated blood, while blue blood is for deoxygenated blood.
The blood in Isabelle's left ventricle would be red, in other words, oxygenated. The left ventricle has oxygenated blood because this blood was first in the right ventricle. Then, it went to the pulmonary arteries, which led the blood to the capillaries close to the alveoli in the lungs. In this area, the deoxygenated blood dropped the CO₂ and took O₂ becoming oxygenated blood. Now, this blood is color-coded red and will go to the pulmonary venules, then to the pulmonary vein, and from there, it will go to the left atrium. Lastly, it will go to the left ventricle to start the systemic circulation, which is the one that distributes the oxygenated blood in the body.

If phosphofructokinase experienced a mutation that interfered with substrate binding, then what other enzyme is going to be most immediately impacted in terms of accessing substrate
Answer: Aldolase
Explanation:
In the metabolism of glucose( glycolysis) phosphofructokinase is an enzyme that catalyzes the conversation of fructose-6-phosphate into fructose-1,6-bisphosphate. This in turn is converted to pyruvate after various steps of enzymatic activity in the glycolytic pathway.
If phosphofructokinase experienced a mutation that interfered with substrate binding, the enzyme that is going to be most immediately impacted in terms of accessing substrate is the ALDOLASE.
Aldolase enzymes cleave fructose-1,6-bisphosphate to triose phosphates( glyceraldehyde 3-phosphate and dihydroxy-acetone phosphate) facilitating an increase in anaerobic production of ATP in muscle.
Therefore, the substrate for binding of aldolase, which is fructose-1,6-bisphosphate is lacking due to mutation of phosphofructokinase enzyme.

Why might it be harder to convince people of the value of forest ecosystem services as opposed to the value of it's economic service?
Answer:
It might be harder to convince people of the value of the forest ecosystem services as opposed to the value of its economic service because truthfully, people have different ideas on what is important and what´s not. So some people may think that the forest has no worth and it doesn´t matter to them if it gets torn down or not, as long as it makes them money, but others may feel that a forest is a special place where animals and such have a place to be free. In the end, it´s always about money and morals. I hope this helps!!

If a gene sequence in one organism is highly similar to the sequence of another gene in another organism it is called
Answer:
This question lacks options, options are: a.related. b. homologous. c protein-coding, d. comparative. The correct answer is b.
Explanation:
Homology refers to the fact in which the sequences of two or more proteins or nucleic acids are very similar due to the fact that they have the same evolutionary origin. Normally two sequences have a high similarity because they are homologous, that is, they share a common ancestor. If two sequences in an alignment are from a common ancestor, mismatches can be interpreted as point mutations (substitutions), and gaps as insertion or deletion mutations introduced into one or both lineages in the time since they diverged.
