PLEASE ANSWER FAST! In the cells of an organism, the synthesis of biological molecules involves chemical reactions that have a positive change in free energy. Which of the following best explains the impact of this change in free energy?
A. It allows spontaneous reactions to occur.
B. It causes a decrease in entropy.
C. It causes the cell to give off heat.
D. It moves the cell toward equilibrium.
When a molecule is biologically molecule synthesized, there will be a monomer unit converted into the polymer, so there is a change in molecule randomness so entropy is decreased, hence option b is correct.
How biological molecules is synthesized?When a biological molecule is synthesized the monomeric unit is converted into the polymeric unit and there will be a synthesis of bonds.
In a biological system, the system moves towards the spontaneous system, and the change in entropy should be increased. The biological system works only when it is a thermodynamically active system.
All the chemical reactions are held to move towards the equilibrium state when a biological molecule is synthesized change in the entropy of the system is decreased but a change in the entropy of the surroundings increases.
Therefore during the synthesis of biological molecules, entropy is decreased, hence option b is correct.

Benefits of Microscopes
3. Consider the technology behind each type of
microscope. Why can light microscopes produce
images in their natural color, while scanning
electron and transmission electron microscopes
only produce grayscale images?
Answer:
See the answer below
Explanation:
The light microscope is able to produce images in their natural color because photons of visible light are utilized as a light source and color is a function of light. Both transmission and scanning electron microscopes are not able to produce images in their natural colors because they utilize beams of electrons to image specimens. They produce grayscale images instead because the regions of the specimen where electrons pass through are usually white while other regions remain black.

How does water form during cellular respiration?
Answer:
The electron transport chain is the third and final step of cellular respiration. Toward the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen that the cell has consumed and reacts with it to form water. In this way, water is created as a byproduct of the metabolism reaction.

Which process does not add carbon to the atmosphere?
Answer:
photosynthesis
Explanation:
Plants and photosynthetic algae and bacteria use energy from sunlight to combine carbon dioxide (C02) from the atmosphere with water (H2O) to form carbohydrates. Oxygen (O2) is a byproduct that is released into the atmosphere.
Photosynthesis does not add carbon to atmosphere.
What is Photosynthesis?
The process by which light energy is transformed into chemical energy in the form of sugars is known as photosynthesis. Using light energy, glucose (or other sugars) are created from carbon dioxide and water, with oxygen being released as a byproduct.
The glucose molecules act as the fuel for the cells; their chemical energy can be obtained through procedures like cellular respiration and fermentation, which result in the production of adenosine triphosphate (ATP), a small energy-carrying molecule, to meet the immediate energy requirements of the cell.
It is possible for organic molecules to integrate inorganic carbon from carbon dioxide; this process is known as carbon fixation, and the carbon in organic molecules is also known as photosynthesis.
Therefore, Photosynthesis does not add carbon to atmosphere.

According to the theory of island biogeography which of the following ecosystems is not an island ecosystem?
A) cave
B) Salt marsh
C) mountaintop
D) desert OasIs
Thanks!
Answer:
Salt marsh
Explanation:
Coastal areas which are surrounded and drained by sea water washed in by the oceans are sea marshes. These are marshy since deep muddy and peat can make up the soil. Peat is made from decomposition process, sometimes many feet high, plant matter. It is submerged in water, bottom-filled, and very fibrous with peat.
How is a species’ population dynamics affected by the presence of another species with the same niche?
Answer:
If two species occupied the same niche, they would be competing for the exact same resources. The competitive exclusion principle states that one of the species would drive the other to extinction.
Two species would be in direct competition for the same resources if they both occupied the same niche. According to the competitive exclusion principle, one of the species would inevitably wipe out the other.
What is niche?It defines how an organism or population responds to the distribution of resources and competitors.
(for instance, by growing when resources are abundant and when predators, parasites, and pathogens are scarce) and how it then modifies those same factors.
According to the competitive exclusion principle, often known as Gauss's law, two species that are vying for the same resource in the same habitat but occupy distinct niches cannot coexist at constant population values.
Two species can dwell peacefully in ecological niches without facing any rivalry. It encourages diversity and keeps the food chain in balance.
Therefore, population dynamics affected by the presence of another species with the same niche.
