How can I extend my knee after surgery?

Answer:

Because objects with larger mass have a larger potential energy, therefor it would have more kinetic energy compared to a less massive object dropped at the same height, thus creating a larger crater.

movement along the sagittal plane that decreases the angle between two bones is Flexion.

Movement along the sagittal plane that decreases the angle between two bones is called flexion. The sagittal plane is an imaginary plane that divides the body into left and right sections. Flexion is a movement that decreases the angle between two bones, such as when you bend your elbow or knee. This movement is the opposite of extension, which increases the angle between bones, such as when you straighten your elbow or knee. Flexion and extension are the two main types of movement that occur along the sagittal plane.

Viruses have no cellular machinery and do not exhibit the characteristics of life until they enter an organism/host and replicate using the host cell.

Viruses are microscopic, acellular organisms that are considered non-living or non-living. In the environment, viruses are considered dead because they do not have cellular properties.

Viruses are the smallest biological particles (the smallest being only 20 nm in diameter). However, since they are not living organisms, they do not belong to any living kingdom. They have no organelles and are unable to perform respiratory or metabolic functions.

Viruses cannot multiply within themselves and must rely on the protein synthesis pathways of their host cell to do so. This is normally accomplished by the virus injecting its genetic material into host cells, co-opting the proteins to generate viral replicates, and causing the cell to burst due to the high amount of fresh viral particles.

Protein channels do not use energy to transport molecules.

This refers to large, complex molecules that perform very important roles in the body. They do the majority of the work in cells and are needed for the structure, function, and regulation of the body's tissues and organs.

Protein channels do not use energy to transport molecules. They allow specific molecules to pass through the cell membrane passively, driven by their concentration gradient. Exocytosis, endocytosis and protein pumps, on the other hand, use energy in the form of ATP to transport molecules across the cell membrane.

RNA polymerase, also referred to as DNA dependent RNA polymerase enzyme, produces RNA from DNA.

Ribosomal RNAs (rRNAs) are produced by RNA polymerase I, mRNAs and short regulatory RNAs are produced by RNA polymerase II, and transfer RNAs are produced by RNA polymerase III (tRNAs). DNA viruses use DNA-dependent DNA polymerases (also known as DNA polymerases) to replicate their genomes and DNA-dependent RNA polymerases to transcribe mRNA (also called RNA polymerases).

Mitosis is the process through which a cell's nucleus divides into two new nuclei. During mitosis, one copy of the DNA is transferred to each of the two daughter cells.

Mitosis is a cell cycle step in which replicated chromosomes separate into two new nuclei. Mitosis produces genetically identical cells with the same number of chromosomes.

As a consequence, mitosis is also known as equational division. Mitosis is usually preceded by the S phase of interphase (during which DNA replication occurs) and is frequently followed by telophase and cytokinesis, which divides the cytoplasm, organelles, and cell membrane of one cell into two new cells with nearly equal proportions of these cellular components.

The lowest energy orbital that can receive an electron is the ground state orbital, which is the lowest energy state an electron can occupy.

This occurs when the electron is in its most stable configuration, meaning that it has the lowest possible energy and is in the lowest possible energy level. To reach the ground state, the electron must release any potential energy it has and move to the lowest energy level. In an atom, this is the closest orbital to the nucleus.

The ground state orbital is also known as the "fundamental state" because it is the most basic and fundamental state of an electron. The properties of the ground state orbital depend on the atom in question and its size. In general, the ground state orbital is the closest orbital to the nucleus and has the lowest energy level of the atom.

Behavioral sciences study the cognitive processes that occur within creatures as well as the behavioural interactions that occur between species in the natural environment. Naturalistic observation, regulated scientific testing, and mathematical modelling are used to conduct a systematic examination and investigation of animal behavior. It uses rigorous definitions and observation to get genuine, objective findings. Psychology, psychobiology, anthropology, economics, or cognitive science are examples of behavioral sciences. Behavioral science has principally demonstrated how human conduct frequently strives to generalize about human behavior as it pertains to society and its influence on society in general.

Behavioral Science was first researched extensively with in early 1900s. John B Watson was a expert pioneer in the field. In 1908, he started teaching psychology at Johns Hopkins University. He was president of the American Psychological Association in 1915. Some of his methodologies for researching behavioral science have been called into question.

The independent variable is not manipulated in a negative control group. this is the key difference between test and negative control groups in an experiment.

In a scientific experiment, a control group is a subset of participants who are kept apart from the other participants so that the results of the independent variable under study are unaffected. As a result, the effects of the independent variable on the experiment are isolated, and it may be possible to rule out other possibilities for the meaning of the results of the experiment. Another distinction that might be made is between positive and negative control groups. The experimental settings in positive control groups are those that ensure a favourable outcome.

The two ways water returns to the atmosphere are Evaporation and Transpiration.

How is water recycled in atmosphere?

Water is recycled in the atmosphere through the process of evaporation. When the sun’s energy heats up the surface of the water, molecules of water absorb the energy and evaporate into the air. As the air rises, it cools and the water vapor condenses back into liquid droplets and forms clouds. When the clouds become full, they release the water as precipitation, which falls back to the surface and the cycle begins again. 

Evaporation is the process by which water in liquid form is converted into water vapor. This can occur when liquid water is heated and the molecules gain enough energy to escape the bonds that hold them together, allowing them to move into the atmosphere as a gas. Transpiration is the process by which water is released from plants in the form of water vapor. Water is absorbed by the roots of the plants and is then released through the stomata of the leaves via evapotranspiration. As the water vapor is released, it cools the plant and helps to regulate its temperature. This process also helps to move water and nutrients throughout the plant.

Therefore, Evaporation and Transpiration are two ways water returns to the atmosphere.
