In a prairie ecosystem, which of the following populations has the most stored energy for use by other organisms?
A prairie grasses
B. prairie dogs
C. coyote
D. hawks
Answer:
I believe the answer would be A. because grass stores the energy it gets from the sun. Therefore it'd have more stored energy for other organisms to use.
Explanation:
In prairie ecosystem, the population with the most amount of stored energy for use by other organisms would be the prairie grasses.
Prairie ecosystems are ecosystems formed from continuous interactions between some biotic and abiotic factors such as plants, animals, fire, temperature, landforms, and precipitation. These interactions lead to the ecosystem being dominated by grasses and forbs as well as animals such as prairie dogs, squirrels, pronghorn, coyotes, and many more.
Prairies grasses are the primary producers in prairie ecosystems. They fix energy directly from the sun through the process of photosynthesis.
Thus, prairie grasses, and generally, producers in any ecosystem, hold the highest amount of energy that can be used by other organisms in the food chain or web of an ecosystem.
Other organisms such as the prairie dogs, coyote, and hawks are consumers.

The relative concentration of solute inside and outside a cell can cause water molecules to move across the membrane. Which phrase would be an alternative title to the diagram
A. Facilitated Diffusion Across a Membrane
B. Osmosis Across a Membrane
C. Exocytosis in a Cell
D. Active transport in a cell
Let's look at the original hypotheses arising from the original question: "Does the size of the
substance affect its ability to diffuse across cell membranes?"
Small substances: If the size of a substance is important in its ability to
diffuse across a cell membrane, then small substances should be able to
freely diffuse across cell membranes.
?
Large substances: If the size of a substance is important in its ability to
diffuse across a cell membrane, then large substances should not be able
to freely diffuse across cell membranes.
?
Do the observations of H+?glucose and cortisol support the
hypotheses?
Explain your answer
Answer:
H1: false, the observations of the molecules do not support the hypothesis...
Explanation:
The cell membrane is comprised of a phospholipid bilayer, proteins, and cholesterol. These components help the membrane to maintain its selective permeability and concentration of solutes and water.
The lipid molecules have polar hydrophilic heads and hydrophobic tails. These only readily allow for the movement of small non polar molecules. Other substances, like charged ions and large molecules require transport proteins to move in and out of the cell. Hypothesis: H+ is small and should be able to move freely through the membrane, While glucose is large and cannot move freely
Observing H+, despite being very small these cannot easily pass through the membrane. They require transport proteins called channels for their free movement or passive movement across the membrane.For glucose, these molecules pass through specialized channels in facilitated diffusion. They move down their concentration gradient into the cell. To move out of the cell against its concentration gradient glucose requires ATP for active transport.Cortisol, is a large steroid hormone, taken into the cell by simple diffusion across the lipid membrane, down its concentration gradient.2. Which biome do we live in with hot summers, cold winters and moderate rainfall?
O desert
O temperate grassland
O tropical forest
O chaparral
This molecule is a product of photosynthesis and is a major source of energy for plants and animals. This molecule is converted to ATP by the mitochondria.
Answer:
This question is asking to identify the molecule being described.
The molecule is GLUCOSE
Explanation:
Photosynthesis is the process by which green plants make their food using energy from sunlight. This food, which happens to be the product of the photosynthetic process is GLUCOSE molecule. Glucose is the source of energy during cellular respiration for plants and animals as it is broken down to synthesize ATP.
The process of cellular respiration, which is carried out by virtually all living organisms make use of the GLUCOSE MOLECULE. The energy stored in the glucose molecule is converted to ATP in the mitochondria.

If it is __________ in the Northern Hemisphere, then it must be __________ in the Southern Hemisphere. A. summer . . . Summer B. spring . . . Winter C. winter . . . Winter D. winter . . . Summe
Answer:
The correct answer is D. winter ... summer
If it is WINTER in the Northern Hemisphere, then it must be SUMMER in the Southern
Explanation:
There are different cycle processes on earth. One of them is the season cycle. Seasons are the result of the Earth´s movement of translation and the inclination of the Earth´s axis with respect to the plane of the orbit. The solar radiation reaches perpendicularilly the surface in different regions of the earth, during an annual cycle. This differential heatting produces the seasons. When it is winter in the northern hemisphere, it is summer in the southern hemisphere. When it is autumn in the northern hemisphere, it is spring in the southern hemisphere. And the exact opposite this occurs. Also, due to the shape of the orbit, summers are warmer in the southern hemisphere.
So, imagine the Earth as a circle. Now imagine that this circle is crossed by a longitudinal line (the earth axis). This axis points to the north pole and to the south pole. Now imagine that this axis is not exactly vertical, but it is inclined.
This circle (the earth) is in an orbit, which has an ovoid shape. This ovoid shape has two extremes, let us call them extreme A and B. Inside the orbit, there is the sun. But the sun is not in the middle. Instead, it is nearer to one of the arbit extremes, let us say it is closer to the B extreme.
During translation, the earth moves along the orbit receiving the sun´s radiation. When the earth is in the B extreme, it is closer to the sun and receives higher radiation. And due to the earth´s inclination, the southern hemisphere is getting much more radiation than the northern hemisphere. At this point, there is summer in the southern hemisphere and winter in the northern hemisphere. But when the earth is in the extreme A of the orbit, the north is getting more direct radiation from the sun. In this extreme, it is summer in the northern hemisphere and winter in the southern hemisphere.
Answer:
If it is winter in the Northern Hemisphere, then it must be Summer in the Southern Hemisphere.

For each molecule of glucose, glycolysis only makes 2 ATP, the Krebs cycle only makes 2 ATP and the ETC makes 34 ATP. If the suspects had given Jared the 2-deoxyglucose poison, would the decrease in ATP concentration be smaller, the same or larger as when they used cyanide? Explain your answer.
(This is from the cellular respiration gizmos lab)
Answer:
Decrease in ATP concentration be larger.
Explanation:
Decrease in ATP concentration be larger because 2-deoxyglucose poison inhibit glycolysis. Glycolysis is the first step of energy production where glucose break down started. If the first step of ATP production is stopped, no energy will be produced so we can conclude that 2-deoxyglucose poison causes decrease in ATP concentration be larger.
The decrease in ATP concentration would be larger when 2-deoxyglucose
poison is given alongside cyanide.
This is because 2- deoxyglucose will inhibit the production of ATP in the
cells of the body. This lead to decreased or no ATP being generated. The
presence of cyanide will also lead to a decrease in the concentration due to
presence of other compounds.
This subsequently leads to a decrease in the concentration of the ATP
present in the solution. This also enables us to deduce that the decrease in
the ATP concentration would be larger.

1. In cellular respiration, stored energy is released from ____________ molecules and transferred to ____________ molecules, which cells can use to provide energy for cellular processes.
Answer:
Glucose, and ATP.
Explanation:
During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP.
In cellular respiration, stored energy is released from glucose molecules and transferred to ATP molecules, which cells can use to provide energy for cellular processes.
CELLULAR RESPIRATION:
Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells. Cellular respiration is a requirement for every living cell in order to produce the energy needed for metabolic activities. Cellular respiration, generally, combines glucose molecule and oxygen according to the following reaction:C6H12O6 + 6O2 → 6CO2 + 6H2O + ATPBased on the equation above, stored energy is released from glucose molecules and transferred to ATP molecules, which cells can use to provide energy for cellular processes.Learn more at: https://brainly.com/question/13721588?referrer=searchResults

18
6
12
2
The number of O2 molecules required for two glucose molecules to undergo cellular respiration would be 12.
First, let us look at the balanced equation of respiration:
[tex]C_6H_1_2O_6 + 6O_2 ---> 6CO_2 + 6H_2O[/tex]
From the equation, for every 1 mole of glucose molecule, 6 moles of O2 is required for complete reaction.
Thus, 2 glucose molecules will require 6 x 2 = 12 moles of O2.
