what would be the advantage of using a molecular model that shows the compounds involved during cellular respiration to compare the amount of carbon released into the atmosphere
a) allows a visual of the process that is not visible to the human eye
b) allows a comprehensive view of the entire carbon cycle
c) allows for the production of certain environmental conditions that could affect the process
d) allows comparison between cellular respiration and photosynthesis in the movement of carbon

Answers

Molecular models help us to visualize the chemical molecules that we can not see with our optical eyes.

Molecular models are three dimensional visual representations of molecule. Molecular models help us to see clearly what a molecule looks like. Using a molecular model, we can have a deeper understanding of the possible transformations that could occur in a molecule.

Carbonic anhydrase is an enzyme that converts carbon dioxide into
bicarbonate so red blood cells can transport it. What is the best way to
increase the rate of reaction?
A-Add more carbonic anhydrase
B-Add more bicarbonate
C-Reduce the amount of water
D-Reduce the amount of carbon dioxide

Answers

Answer:

A

Explanation:

Increase enzyme concentration so more enzymes can react with carbon dioxide to form bicarbonate. D would make the reaction slower, C does not relate to the question and B is the product so would not help increase the rate of the reaction, only A

A team of biologists discovers a new ecosystem with lush vegetation but no bodies of water nearby. They monitor the ecosystem for a year, recording daily rainfall during that time. Which statement best explains the lack of bodies of water in this ecosystem?

The water is permanently held in clouds.
Water stays predominantly in groundwater sources.
Evaporation transfers rainwater into the atmosphere.
Water is frozen underground instead of flowing on the surface.

Answers

The statement that best reveals the scarcity of bodies of water in this ecosystem is as follows:

Evaporation transfers rainwater into the atmosphere.

Thus, the correct option for this question is C.

What is an Ecosystem?

An ecosystem may be defined as a place or an area where individuals of different species live together and interact with one another for the purpose of food, shelter, and space.

A newly formed ecosystem that a team of biologists identified significantly illustrates the scarcity of water or no bodies of water near its geographical locations. The most prominent and valid reason for this claim is the rate of evaporation that converts rainwater into vapor form in the atmosphere.

The amount of water in any ecosystem may significantly be found less or completely absent when the rate of evaporation is significantly high in that ecosystem. It is based on the fact of temperature.

Therefore, the correct option for this question is C.

if a cell is placed in hypotonic solution water will flow

Answers

Answer: there will be a net flow of water into the cell

Explanation: If a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume. If the solute concentration outside the cell is lower than inside the cell, and the solutes cannot cross the membrane, then that solution is hypotonic to the cell.

IN FIVE TO TEN SENTENCES, DISCUSS the major concepts of populations, and
how these concepts contribute to balance in the ecosystem.

Answers

Answer:

A small change in our ecosystem could forever impact the whole web. For example, if bees were to go extinct, then flowers wouldn't be able to reproduce (since bees fertilize the flowers). Meaning the flowers would die out. And a lot of living things, including humans, depend on bees. Or let's say that a sharks were to go extinct. They play a major role in our ecosystem, because they eat fish and other sea creatures. The prey would then grow in population. Which would lead to a disaster. So in short terms, every creature in the ecosystem is vital to maintain the balance. I hope this helps!! :)

Which colony was owned and run by the West India Company?New Netherlands New York New Jersey New France Joan, an employee of Great American Market, was warned about her excessive absenteeism several times, both verbally and in writing. The written warning included notice that "further violations will result in disciplinary actions," including suspension or discharge.A short time after the written warning was issued, Joan called work to say she was not going to be in because her babysitter had called in sick and she had to stay home and care for her young child. Joan's supervisor, Sylvia, told her that she had already exceeded the allowed number of absences and warned that if she did not report to work, she could be suspended. When Joan did not report for her shift, Sylvia suspended her for fifteen days.In a subsequent hearing, Joan argued that it was not her fault that the babysitter had canceled, and protested that she had no other choice but to stay home. Sylvia pointed out that Joan had not made a good faith effort to find an alternate babysitter, nor had she tried to swap shifts with a co-worker. Furthermore, Sylvia said that the lack of a babysitter was not a justifiable excuse for being absent. Marie is reading a271-page book. She has already read119pages.
