a food chain
Answer: A community
Explanation: Abiotic is not living, all the things mentioned are alive so this is not correct.
A population is a number of organisms of the same species living together in an area at the same time.
A community is an interacting group of various species in a common location. The common location here is a pond.
A food chain shows the flow of energy and material being transferred from one organism to the next. The example given could be a food chain, but what disqualifies it from being a food chain is the perch it does not provide energy to any of the organisms listed in your example.

Invertebrates have a higher net production efficiency than mammals. Which statement most likely explains this observation? A. Invertebrates are more abundant than mammals in an ecosystem. B. Mammals maintain their body temperature; invertebrates don't. C. Most mammals are secondary consumers. Most invertebrates are primary consumers. D. Invertebrates have smaller bodies than mammals.
Answer:
C. Most mammals are secondary consumers. Most invertebrates are primary consumers.
Explanation:
Net production efficiency (NPE) refers to how efficient an organism at one trophic level is in utilizing and transferring energy to the next trophic level. Consumer organisms obtain energy (from biomass) when they feed on other organisms. They then use this energy for their metabolic activities and transfer the rest when eaten or fed on.
The net production efficiency decreases with increasing trophic level because higher organisms use more energy than lower ones. In this case, invertebrates use energy they obtained lesser or more efficiently than mammals, hence, making them have a HIGHER net production efficiency than mammals. Therefore, invertebrates are mostly primary consumers and utilize energy lesser than mammals which are mostly SECONDARY CONSUMERS.
Please hurry! What is our body’s hidden strength?
Answer: One major clue is that we humans are, quite simply, stronger than we realise. Our movements are controlled by the contraction of muscles through signals relayed by nerves. When going about our daily lives, our bodies tend to use whatever the least amount is of muscle-and-nerve "motor units" to perform an action.

Which three minerals are most commonly found in the igneous rock granite?
Answer:
Granites and rhyolites consist predominantly of quartz and potash feldspar; gabbros and basalts, predominantly of pyroxene and plagioclase feldspar. Other rock types have intermediate mineral compositions.
Explanation:
It is made up of sodium feldspar, potassium feldspar, and coarse quartz grains (10–50%). More than 80% of the rock is composed of these minerals.
What is igneous rock granite?Granite is a pale-colored plutonic rock that is mostly found in mountainous regions of the continental crust.
Quartz and potash feldspar make up the majority of granites and rhyolites, whereas pyroxene and plagioclase feldspar make up the majority of gabbros and basalts. Other types of rocks contain mineral compositions that are in between.
Magma, which is a molten substance that flows and hardens underground while slowly cooling, is the source of intrusive rocks.
Therefore, the majority of the continental crust is composed of granite, the most common kind of igneous rock, intrusive igneous rock is granite.

What were the major contributions of the H.M.S. Challenger to the study of oceanography? How did its expedition contribute to future studies of the ocean?
Answer:
The H.M.S. Challenger embarked from Portsmouth, England on December 21, 1872 and changed the course of scientific history. Physicists, chemists, and biologists collaborated with expert navigators to map the sea. This interdisciplinary spirit has continued to the present day. During the 4 year journey, the voyages circumnavigated the globe, sounded the ocean bottom to a depth of 26,850 feet, found many new species, and provided collections for scores of biologists.
C. Wyville Thomson led the expedition but died of exhaustion from the journey, which ended on May 24, 1876. The Challenger had zig-zagged around the globe and had visited every continent, including Antarctica.
The reports of the Challenger expedition were supervised by Sir John Murray, whose biological conclusions were of great importance to the later development of marine biology. He concluded, for example, that the deep-sea fauna was not "ancient," in that it did not resemble the faunas found in ancient fossil deposits.

The H.M.S. Challenger changed the course of scientific history. The expeditions circumnavigated the world, sounded the ocean floor to a depth of 26,850 feet. Itdiscovered numerous new species, and supplied collections for hundreds of researchers over their four-year adventure. The Challenger was a corvette, a military ship that went by sail but had auxiliary steam power to help steady the ship during sampling. The expedition was commanded by C. Wyville Thomson, who died of fatigue on May 24, 1876, at the end of the voyage. The Challenger has zig-zagged its way around the world, stopping at every continent except Antarctica. Sir John Murray oversaw the Challenger expedition's reports, and his biological results were crucial to the eventual development of marine biology. For example, he decided that the deep-sea fauna was not "old" since it did not reflect faunas found in ancient fossil beds.

Which of the following best describes the relationship between the endoplasmic reticulum and the plasma membrane in eukaryotic cells?
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, there is a distinct relationship between the endoplasmic reticulum and the plasma membrane. The endoplasmic reticulum are responsible for protein synthesis which are used by the remaining organelles (including the membrane) to function. The endoplasmic reticulum is also involved in lipid synthesis and has a network of tubules (which are used for carrying materials throughout the cell) that can deliver lipids into the cell membrane. These lipids are responsible for the semi-permeability function of the cell/plasma membrane.

he cell cycle is essential for ensuring that our cells don't grow too large. Explain why it is necessary for cells to remain small in size.
Answer:
it is necessary for cells to remain small in size because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients and exchanging materials between the inside and outside of cells.
Cells are small so they can have an efficient surface area to volume ratio. This is going to allow the cell to easily excrete waste product.
That is why the cell needs to be small. The smaller it is, the larger the surface area to volume ratio is.
