What is a small ecosystem in danger of compared to a large and diverse ecosystem?
Answer:
See the answer below
Explanation:
A small ecosystem is in danger when compared to a large and diverse ecosystem because the genetic variability in a small ecosystem is low and a small disruption can wipe out the populations within the ecosystem. This is unlike in a large ecosystem where this is a high genetic variability that gives the populations within the ecosystem resilience against disturbances.
There are enough alleles within the genetic pool of a large and diverse ecosystem to withstand disturbance regimes unlike in small ecosystems where the alleles are few. Hence, a little disturbance can endanger the entire population in a small ecosystem and put them at the risks of extinction.

1)When a phosphate is transferred from ATP, it can phosphorylate another molecule. How could this assist in allowing a protein to transport molecules against their concentration gradient?
2)What is it about the structure of ATP that contributes to its ability to act as an energy currency?
Answer/Explanation:
1) When phosphate is transferred from ATP, (which forms ADP and releases energy) it can phosphorylate another molecule. When this molecule is phosphorylated. It could become "energized" as it enters a higher energy state.
In this higher energy state, the protein has the energy to transfer molecules against a concentration gradient, which is an active process (requires energy).
2) Adenosine triphosphate contains three phosphate groups. The phosphate bonds are high energy. When ATP is hydrolyzed (water is added), these high energy phosphate bonds are broken and energy is released. This forms adenosine diphosphate (ADP).
1) When a protein molecule is phosphorylated, it becomes activated or powered and enables it transport molecules against their concentration gradient.
2) The bond that holds phosphate bonds in ATP gives it the ability to act as an energy currency.
ADENOSINE TRIPHOSPHATE (ATP)
Adenosine triphosphate, commonly known as ATP, is the means by which energy is stored and released in the cells of biological organisms. ATP is structurally made up of a ribose sugar, an Adenine base and three phosphate groups. The phosphate groups are held together by a bond called phosphoanhydride bond. ATP stores energy when one phosphate molecule is added to ADP while it releases energy when one phosphate group is broken. This latter process is called PHOSPHORYLATION. The ability of ATP to lose and accept phosphate group in its structure makes it perform the role of an energy currency in the cell.However, when a phosphate group is added to a molecule e.g. a transport protein, it is said to be phosphorylated. This means it will become activated or powered up to perform the task of transporting molecules against their concentration gradient.Learn more: https://brainly.com/question/15585148?referrer=searchResults
How is energy transferred from one organism to another ? A. by one side draining the energy of the other organism B. by one organism eating another organism C. by one organism giving the other one energy D. by one organism attacking the other organism
Linnaeus developed two groups for classifying organisms: genus and .
Answer:
Species
Explanation:
Carl Linnaeus was a Swedish scientist who developed a formal system of naming organisms- bionnomial nomenclature
The first part of the name identifies the genus to which the species belongs, and the second part identifies the species within the genus.
For example the tiger is called "Panthera tigris". The species is tigris (tiger).
The genus is Panthera (which also includes the lion (Panthera. leo), the jaguar (Panthera onca), and the leopard (Panthera pardus). The species is "tigris"
Answer:
Species

Which statement provides a conclusion about the transport of water in and out of cells based on the results of the student's experiment? A. Water moves freely both inside and outside the cell independent of the solute concentration. B. Water movement into the cell is dependent on the percent concentration of solutes both inside and outside the cell. C. Water transports solutes out of the cell to balance the percent concentration of solutes both inside and outside the cell. D. Water moves into the cell solutes move out of the cell to ensure their concentration is balanced both inside and outside the cell.
Answer:
B.
Explanation:
The transport of water in and out of cells based on the percent concentration of solutes both inside and outside the cell.
The movement of water in and out of the cell is called osmosis. In the process of osmosis, water or solvent moves from low to high concentration of solute (towards high solute concentration). For example, if a cell is placed in a salt (solute) solution, the water will move out of the cell or towards high salt concentration and the cell will get shrink.
Hence, the correct answer is "B."

Explanation:
If PCBs escaped into the river in large amounts and entered the lower levels
of the food chain, what would be the likely outcome?
Answer:
Over time, PCBs would collect in top predators such as salmon, making them unsafe for human consumption.
Explanation:
PCBs last a long time in the environment before breaking down and may find their way into the food chain. Low levels of PCBs can be found in fish, shellfish, meat, poultry, milk, dairy products, and other foods. Since PCBs have not been made since 1977, the levels in the environment have been declining over the past several years. Predators at or near the top of the food chain (e.g. birds, fish) have the highest levels of PCBs in their bodies.
Why does herding help a horse survive better?
Answer:
In natural environments, horses typically live in relatively stable social units. Horses live in herds so that they are able to fulfil their basic needs, which are to avoid danger or harm, and to reproduce successfully and bring up healthy foals.

When you exercise and your
body temperature rises, how
does your body maintain
homeostasis? What are some
things that happen? How do you
cool off? What happens to your
breathing? Blood flow?
Answer:
During exercising, your body's temperature levels up and one of the body's mechanisms of homeostasis is perspiration, which is sweating. Sweat helps cool off the body by excreting the heat to the exterior surface f the body and it gets rid of excess fluids and salts. The breathing rate also gets higher due to the physical activity. Blood flow will increase as well, as the blood vessels dilate and get wider allowing more blood to pass through.

Can someone please give me An example of an ionic bond with a positive ion and negative ion
Answer:
NaCl
Explanation:
ionic bond is the bond results from the electro static force of attraction between oppositely charged ions in other words its the linkage formed by the transfer of one or more electron from one atom to another atom
Na gives it electron to chlroine so Na becomes positively charged and Cl becomes negatively charged and they attract each other to form ionic bond
Na is positive Cl is negative

How is petroleum formed ?
(SCIENCE)
Answer:
Petroleum is a fossil fuel, meaning that it has been created by the decomposition of organic matter over millions of years. Petroleum is formed when large quantities of dead organisms–primarily zooplankton and algae–underneath sedimentary rock are subjected to intense heat and pressure.
