Explanation:
When you add extra pulleys, the minimum force that is needed to be given off by the person pulling lowers. For example if you have one pulley and pull on it, you require more force to move the object than your friend with two pulleys. He requires half the force that you do to move the object.
Which two species are most closely related?
Answer:
Two species (B & C) are more closely related to one another than either one is to a third species (A) if, and only if, they share a more recent common ancestor with one another (at Time 2) than they do with the third species (at Time 1).
Explanation:
B and C species are closely related in this phylogenetic tree. A diagram that shows the evolutionary relationships between different species or groups of animals is called a phylogenetic tree.
By showing the branching points where species diverged from a common ancestor, it exemplifies the shared ancestry and evolutionary history of species. The arrangement of species on branches that have a recent common ancestor reflects the degree of relatedness between organisms.
Closely related species tend to cluster together on such branches. Phylogenetic trees are constructed based on similarities and differences in genetic structure, physical characteristics, or other traits observed in different animals. They are important tools in the discipline of evolutionary biology to study patterns of variation and the development of life on Earth.

Answer:
gravity
Explanation:
the sun has a gravitational pull that keeps all the planets in orbit and prevents them from just floating away.
Answer:
The reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

Which would probably have the greatest effect on a protein's function—a change to the primary, secondary, or tertiary structure? Explain your answer.
Answer:
There are 20 different standard L-α-amino acids used by cells for protein construction. Amino acids, as their name indicates, contain both a basic amino group and an acidic carboxyl group. This difunctionality allows the individual amino acids to join in long chains by forming peptide bonds: amide bonds between the -NH2 of one amino acid and the -COOH of another. Sequences with fewer than 50 amino acids are generally referred to as peptides, while the terms, protein and polypeptide, are used for longer sequences. A protein can be made up of one or more polypeptide molecules. The end of the peptide or protein sequence with a free carboxyl group is called the carboxy-terminus or C-terminus. The terms, amino-terminus and N-terminus, describe the end of the sequence with a free α-amino group.
The amino acids differ in structure by the substituent on their side chains. These side chains confer different chemical, physical, and structural properties to the final peptide or protein. The structures of the 20 amino acids commonly found in proteins are shown in Figure 1. Each amino acid has both a one-letter and three-letter abbreviation. These abbreviations are commonly used to simplify the written sequence of a peptide or protein.
figure1-Protein-Structure
Depending on the side-chain substituent, an amino acid can be classified as being acidic, basic or neutral. Although 20 amino acids are required for synthesis of various proteins found in humans, we can synthesize only ten. The remaining 10 are called essential amino acids and must be obtained in the diet.
The amino acid sequence of a protein is encoded in DNA. Proteins are synthesized by a series of steps called transcription (the use of a DNA strand to make a complimentary messenger RNA strand – mRNA) and translation (the mRNA sequence is used as a template to guide the synthesis of the chain of amino acids which make up the protein). Often, post-translational modifications, such as glycosylation or phosphorylation, occur which are necessary for the biological function of the protein. While the amino acid sequence makes up the primary structure of the protein, the chemical/biological properties of the protein are very much dependent on the three-dimensional or tertiary structure.
A change to the PRIMARY structure WILL HAVE the greatest effect on a protein's function.
The primary structure of a protein refers to the linear sequence of amino acids within a polypeptide chain.A change in the protein primary structure will change protein properties and likely will also alter their functions.The secondary structure of a protein refers to the specific arrangement of groups of amino acids. The most common types of secondary structures in proteins include alpha helix and beta sheets.The tertiary structure refers to the three-dimensional shape of the protein. There are two major main classes of protein tertiary structure: fibrous and globular.The quaternary structure refers to the association of different protein subunits to form a multimeric protein.In conclusion, a change to the PRIMARY structure WILL HAVE the greatest effect on a protein's function.

The main difference between the water cycle and the other chemical cycles is that water
never changes its structural form (H2O) .
is much slower than the other cycles.
creates completely new substances.
is made from matter that has been here since the world was formed.
Answer:
The answer is A.
Explanation:
Other cycles change their structural form often, but water does not change it's structural form in the water cycle, which is H2O so that is one main difference between the water cycle and oither checmical cycles. So, your answer is A.
The main difference between the water cycle and the other chemical cycles is that water never changes its structural form (H2O). Thus, the correct option for this question is A.
What is the water cycle?The water cycle may be defined as a type of biogeochemical cycle that significantly involves the gradual and continuous movement of water and its derivative products within the Earth and atmosphere.
The water cycle remarkably consists of three major processes. They are as follows:
Evaporation: a process through which a liquid converts into gas.Condensation: a process through which gas converts into liquid.Precipitation: a process through which liquid water falls on the earth's surface.The most important concept of the water cycle is that the structural form of water remains constant and the same throughout the process. This property of water differs from other chemical cycles because such cycles involve the alteration in their fundamental component.
Therefore, water never changes its structural form (H2O) is the main difference between the water cycle and the other chemical cycles. Thus, the correct option for this question is A.

the molecule that is formed as a result of the acceptance of hydrogen ion and the final acceptor molecule.
Answer:
H2O (Water)
Explanation:
Oxygen (O2) is the final acceptor molecule after the process of aerobic respiration. Specifically, it accepts hydrogen ions at the end of the electron transport chain, the main energy-generating stage of cellular respiration.
This is why oxygen is needed to form large amounts of cellular energy, as without it, the electron transport chain cannot proceed. When oxygen accepts hydrogen ions, it forms water, a byproduct of aerobic respiration.
