In an ecosystem, a deer consumes grass. What percentage of energy will the deer acquire from the grass? 0. 1% 1% 10% 100%.
In an ecosystem, the energy is transferred between the organisms participating in the food webs from producers and consumers.
The percentage of energy transferred to the deer after feeding on the grass is 10%.
The 10% law of the energy states that:
1. The food chain at each trophic level passes or transmits only 10% of the energy and 90% of the energy is lost as heat.
2. The amount of energy at each trophic level decreases, such that the producers if consuming the 100 J of energy, the deers or primary consumers at the first trophic level will have only 10% of the energy.
Thus, the deer will possess only 10% of the energy at each trophic level, following the 10% law.
The correct answer is Option C.

if the atmosphere is like a greenhouse what is the glass?
Answer:
earth's atmosphere is like the glass in a greenhouse because sunlight streams through the atmosphere and heats the Earth. As the heat radiates up from the Earth's surface, some escapes into space. The rest of the heat is absorbed by gases in the troposphere and warms the air.

Where is the rainshadow area on the Big Island of Hawaii? Please help
Answer:
Applied to the Big Island, since the trade winds blow from the northeast and must pass over the mass of Mauna Kea and Mauna Loa, it means that the Hilo side is considerably rainier than the Kona side. The best place to view this rain shadow effect is to drive from Kohala to Hilo through the town of Waimea.

what specific parts of the brain have been affected by the injury so as to cause the muscle weakness and language problems?
Publishing can play a major factor in how a scientist is regarded. This is because the number of publications scientists produce can affect who gets a raise, who gets hired, who gets fired, and who gets funding to do more experiments. Consequently, a phenomenon is known as “salami-slicing” has arisen in science. Instead of publishing a large comprehensive study containing all the results as one large paper, scientists often slice up the work into the smallest units possible and publish these as several separate papers—often in different journals.
Research the phenomenon of scientific salami slicing, and list at least two possible ethical problems that can arise from this practice.
Explain how this practice can affect the way that scientific information is disseminated to nonscientists.
Create a suggestion for a policy that scientists or science journals could follow that would reduce the amount of salami-slicing that occurs in research. Suggest any problems that the policy might cause.
Salami slicing is the procedure of dividing one single article research into several publications. It is an unethical practice because hampers the healthy competence between scientists for research (job) positions.
In the phenomenon referred to as 'salami slicing', a group of similar research articles published by the same research group are considered 'slices' of the same salami.
This practice can affect not only the work of scientists but also journalists who might report the same results once and again.
A possible solution for this problem is to create a Review Board consisting of experts capable of identifying salami slice articles and then punish the responsible parties.

the membrane activity most nearly opposite to exocytosis is:
Answer:
endocytosis
Explanation:
Endocytosis is defined as the process of trapping a particle or even a substance from the external environment by the process of engulfing it. The flexibility of the cell membrane helps the cell to engulf the food and also other materials from the external environment. Such a process is called endocytosis whereas exocytosis is the fusion of secretory vesicles with the plasma membrane and results in the discharge of vesicle content into the extracellular space

A student is investigating the process of osmosis. She fills a medicine dropper with red
blood cells. Next, she creates a saline solution that is isotonic to the red blood cells.What will most likely happen to the red blood cells after they are placed in the
solution?
A. Water will exit the cells and cause them to shrink in size.
B. Water will enter the cells and cause them to grow in size.
C. Water will neither enter or exit the cells and their sizes will remain the same.
D. Water will enter and exit the cells at a steady rate and their sizes will remain
the same.
Answer: D. Water will enter and exit the cells at a steady rate and their sizes will remain the same.
Explanation:
Osmosis occurs when the salt content is NOT the same as our red blood cells: the salt or lack of it causes our RBCs to swell or shrink. Isotonic fluid has the same salt content as our RBCs. This is why it's important to watch salt intake in congestive heart failure.
