why do food chains in an ecosystem rarely contain more then five organisms
Why do food chains in an ecosystem rarely contain more than five organisms? ... Nutrients are lost from the ecosystem when organisms die. The conversion of food into growth by an organism is not very efficient. Energy is recycled by the decomposers back to the producers.

How are DNA and proteins related
Answer: Carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies. Each DNA sequence that contains instructions to make a protein is known as a gene
Answer:
The significance of DNA is very high. The gene's sequence is like a language that instructs cells to manufacture a particular protein. An intermediate language, encoded in the sequence of Ribonucleic Acid (RNA), translates a gene's message into a protein's amino acid sequence. It is the protein that determines the trait.

What does lemon juice, snake venom and cyanide have in common?
Answer:
enzymes are protein molecules that act as catalysts, speeding up chemical reactions without themselves getting used up. Each enzyme will only speed up a specific reaction, for example, catalase will speed up the decomposition of hydrogen peroxide into water and oxygen but it will not speed up the breakdown of starch into glucose. Enzymes (e.g. catalase) have active sites with specific shapes that bind to the substrate molecule (e.g. hydrogen peroxide) forming an enzyme-substrate complex. The enzyme-substrate complex then breaks down into the enzyme and product, allowing the enzyme to go on and react with another substrate molecule. Temperature and pH affect enzyme function because they can change the shape of the enzyme’s active site, preventing it from binding to the substrate, just as a broken lock will no longer fit the key. When the shape of an enzyme changes we call this denaturation. Any factor that increases the frequency of collisions between enzymes and substrates (increasing concentration, surface area or temperature) will increase the rate of reaction.

How does the Gulf Stream affect weather in the United States? A. It brings cooler temperatures from the poles. B. It brings cooler temperatures from the tropics. C. The warm surface currents help create storms and fog. D. The cool surface currents produce cooler weather and fog.
Answer: C. The warm surface currents help create storms and fog.
Explanation:
The gulf stream can be defined as strong ocean currents that brings about the warm wind currents from the oceanic water of the gulf of Mexico to the eastern coastal areas of the United States. These wind currents bring warm weather conditions in the United States. The strong wind currents can also cause storms and fog in the coastal areas of the United States.

explain how animal cells differ from plant cells with respect to the effects of net water movements
Answer:
Terms in this set (4) Animal cells do not have a cell wall, meanwhile plant cells do have a cell wall. As a result, water passes freely in an animal cell due to osmosis. In a hypotonic solution, there is more free water outside the cell than inside the cell.
Bats are common in Texas especially in rocky regions bats with longer hang claws have demonstrated higher fitness because of their ability to cling to rock while resting this adaptive on is becoming more frequent in the population.What mechanism of evolution is this
Answer:
Natural selection
Explanation:
Natural selection is the mechanism of evolution in which organisms evolve in order to adapt the changes in the habitat for their survival. Living organisms are naturally variable and adjust themselves according to their surroundings.
In the given example, bats in Texas evolve themselves with longer hang claws to adapt the rocky nature of the surrounding. These longer hang claws provide them the ability to cling to the rock, which is an adaptive feature of bats that is influenced by the environment.
Hence, the correct option is "Natural selection".

Geese fly in a v-like formation when migrating. Which statement is evidence that supports advantages of this group behavior? (4 points)
A) Birds can work together to find food and shelter.
B) Birds conserve energy and reduce wind resistance.
C) Birds need to move faster to avoid being seen by predators.
D) Birds can compete for mates when they fly together.
Answer:
B
Have a nice day :D
Birds conserve energy and reduce wind resistance when they fly in V-like formation.
Why Geese fly in a V-like formation?Flying in a v-like formation allows geese to conserve energy and reduce wind resistance as they migrate. The lead goose breaks the wind for the rest of the group, which allows the other geese to fly more efficiently and use less energy. This group behavior helps the geese to cover long distances during migration, as they are able to fly for longer periods of time without tiring.
The other options do not provide evidence of advantages of this group behavior. Option A) may be true, but it is not specific to flying in a v-like formation. Option C) is not necessarily related to group behavior, as geese may need to move faster for other reasons. Option D) is not relevant to the topic of migration.

Which process occurs within the mitochondria?
lactic acid fermentation
alcohol fermentation
glycolysis
Krebs cycle
The correct answer is D i.e. krebs cycle occurs in mitochondria.
what is mitochondria?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP)
what is krebs cycle?
The tricarboxylic acid (TCA) cycle, also known as the Krebs or citric acid cycle, is the main source of energy for cells and an important part of aerobic respiration. The cycle harnesses the available chemical energy of acetyl coenzyme A (acetyl CoA) into the reducing power of nicotinamide adenine dinucleotide (NADH).
it is a closed cycle which produce 8 intermediates which are;-
