A student swings his keychain around in a circle. What is the source of the centripetal force for this action?
Answer:
The correct answer will be- tension
Explanation:
Centripetal force is the force acting on the object moving in a circular path with direction towards the center. The centripetal force causes the object to follow a curved path.
Three forces together act on the string with key: Tension (a force acting on the key chain due to string), gravity (the downward force), and friction (resisting force). Out of these the main source of action of centripetal force is the "tension" applied by the string on the key-chain.
Thus, tension is the answer.
a human impact on the nitrogen cycle, such as fertilizer
When farmers harvest crops, a lot of the plant material is also removed. Little is left to decay and return nitrogen to the soil. If the soil stays this way, it will start producing fewer crops. Fertilizer contains the nitrogen compounds that are essential for plant growth. It can be used to replace the nitrogen in the soil to ensure the growth of healthy crops.

Chains of amino acids make___ which can join together to make a ____
Amino acids form chains called peptides, which can join together to form polypeptides. When many amino acids are linked, or when multiple polypeptides combine, they form proteins. The characteristics of a protein are determined by the sequence and arrangement of amino acids in the chain.
Explanation:Chains of amino acids form short chains called peptides. These peptides can join together to form longer chains, which are referred to as polypeptides. When the number of amino acids joined together becomes very large, or when multiple polypeptides are used as building subunits, the resulting macromolecules are known as proteins.
Each amino acid is attached to another amino acid by a covalent bond, known as a peptide bond, which is formed by dehydration synthesis. Dehydration synthesis in this context involves the carboxyl group of one amino acid combining with the amino group of another releasing a water molecule, hence the term dehydration. The process can continue, linking numerous amino acids together in a chain.
The sequence, number, and specifically the arrangement of these amino acids in the chain ultimately determines the protein's unique shape, size, and function.

1. The graph below depicts the frequency of expression of the coloration of beetles on an island:
Graph is the 1st Pic
Birds are the main predators of these beetles; they hunt the beetles by sight and pick them up off of the tree bark where they feed. A logging company clears the trees off of the island and plants younger trees as a replacement. Trees with light bark are planted on one side of the island and trees with dark bark are planted on the other side of the island. What do you predict would happen to the range of coloration in the populations of beetles on each side of the island? Select TWO answers, one to represent the beetles living on the light colored trees and one to represent the beetles living on the dark colored trees. (2 points)
A. graph 2 below
B. graph 3 below
C. graph 4 below
D. graph 5 below
Graph 3 represent the beetles living on the light colored trees and graph 5 represent the beetles living on the dark colored trees.
Options B and D are correct
How do we explain?These beetles are likely to experience selective pressure favoring lighter coloration because lighter-colored beetles would be better camouflaged against the light bark, making them less visible to birds. Over time, natural selection may lead to an increase in the frequency of lighter-colored beetles in this population.
In the same way, beetles on the dark-colored trees may experience selective pressure favoring darker coloration. Darker-colored beetles would be better camouflaged against the dark bark, providing them with a better chance of avoiding bird predation. Over time, natural selection may lead to an increase in the frequency of darker-colored beetles in this population.

They include monosaccharide and polysaccharides.
They provide immediate energy boost or short term energy storage for animals as well as long term energy storage for plants and animals.
PROTEINS are molecule composed of amino acids
They serve as catalysts which speeds up chemical reactions by lowering activation energy.
They are used to form bones and build muscles.
LIPIDS are a large group of molecules which are not soluble in water .They provide long-term energy storage for animals.

which statement best describes the presidents role in the federal legislative process?
A- THE PRESIDENT MUST APPROVE BILLS BEFORE CONGRESS CAN VOTE ON THEM
B-THE PRESIDENT DETERMINES WHETHER TO SIGN OR VETO BILLS PASSED BY CONGRESS
C-THE PRESIDENT CAN ORDER A FILIBUSTER OF BILLS TO PREVENT A VOTE BY CONGRESS
D-THE PRESIDENT SETS THE RULES FOR FLOOR DEBATES ON BILLS PRESENTED TO CONGRESS
B-The president determines whether to sign or veto bills passed by congress.
Explanation;The president's only role in the federal legislative process is to sign or veto the bills that are passed by the Congress.When the president signs a bill that has been passed by the congress it becomes a Law. On the other hand, if the presidents vetoes the bill then it goes back to the congress. The congress has power to override the veto by the president with a two-third votes by the two houses.However, the override by the congress are not common, and usually the presidential vetoes kills bills.Answer:
The answer is B.

What's the difference between primary succession and secondary succession
Final answer:
The difference between primary and secondary succession is that primary succession occurs on newly formed land with no soil, requiring pioneer species to create soil, while secondary succession occurs on disturbed land with existing soil, allowing for faster recovery.
Explanation:
Ecological succession is the process where a community experiences a sequence of changes with the appearance and disappearance of species over time. The main difference between primary succession and secondary succession lies in the condition of the environment where the succession begins.
Primary succession occurs in areas where no soil exists because it's a newly formed or exposed environment, such as land formed from lava flow or locations where glaciers have retreated. Here, the environment is colonized by pioneer species which can grow in such harsh conditions and gradually create soil by breaking down rock and contributing organic matter as they die off.
In contrast, secondary succession happens in areas that were once home to existing life but were disturbed by events like wildfires or human activities. In these cases, soil is already present, and remnants of the destroyed community provide a basis for new growth. Succession in these situations tends to be faster than primary succession because the soil already contains nutrients needed for plant growth.
