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.
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.

A K system is an allosteric enzyme for which the apparent affinity of the enzyme for its substrate is altered in the presence of effector and for which the apparent Vmax does not change. ... KM is a constant for any enzyme.
if a cell is placed in hypotonic solution water will flow
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.
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
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.

Explanation:
An organism has brown fur, eats nuts and berries, and hibernates in the winter. What biome is this organism likely a part of? Explain your thinking.
Answer:
Forest.
Explanation:
Berries and nuts are typically fruits and products of trees, and there must be plentiful amount in which to have a population (though it states only an organism, but it can be assumed). Brown fur is typically camo against a brownish background, which can be reflected essentially through bark & wood of trees.
*Most likely the given organism is a squirrel, which typically prefer forest or habitats with trees or tree-like objects.

chipmunks
Explanation:
as you know squirrels have brown fur and eats nuts and fruits but many squirrels does not hibarnate in winter so the squirrel is not actual answer so chipmunks is the species of animals which have brown fur and eats nuts and fruits and hibarnates in winter.

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
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

How is bohr's atomic model different from rutherfords model
Answer:
Rutherford described the atom as consisting of a tiny positive mass surrounded by a cloud of negative electrons. Bohr thought that electrons orbited the nucleus in quantised orbits.
Explanation:
Bohr built upon Rutherford's model of the atom. In Rutherford's model most of the atom's mass is concentrated into the centre (what we now call the nucleus) and electrons surround the positive mass in something like a cloud.
Bohr's most significant contribution was the quantisation of the model. He believed that electrons moved around the nucleus in circular orbits with quantised potential and kinetic energies. So it was not possible for electrons to occupy just any energy level.

Explanation:
Ciara believes that whenever
the Moon is in the position that
is shown from above (top view)
in Diagram A, the Moon always
looks completely dark in the
view from Earth, as shown in
Diagram B.
Is Ciara correct? If she is
correct, explain why the Moon
always looks dark from Earth in
that position, and explain how
she should show light in
Diagram A. If she is incorrect,
explain how else the Moon can
look when it is in that position.
Given the diagrams attached in the question, we can conclude that Ciara is correct in her prediction of the lunar cycle.
Ciara is correct in her prediction given that if the moon should be in this position, on the far side of the earth in relation to the sun, it would appear, when viewed from earth, to be completely dark. The reason behind this is that the moon does not have an internal light source. What this means is that the moon, much like the earth and unlike the sun, cannot generate light on its own.
Therefore, the light that we see when looking at the moon from the Earth is actually just reflected sunlight bouncing off the surface of the moon. The diagram shows that the moon is on the far side of the Earth in relation to the sun, meaning that in this case, the Earth would block most if not all of the light from reaching the moon, giving it a dark appearance.

C. Humans can have dimples or not have dimples
Explanation:
The presence of freckles and dimples are just a few examples of Mendelian traits that are passed down from our parents. Examples of traits are the presence of freckles, blood type, hair color, and skin tone. Mendelian traits are traits that are passed down by dominant and recessive alleles of one gene.

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