Answer:
The average kinetic energy of the molecules is proportional to absolute temperature. At any given temperature, the molecules of all gases have the same average kinetic energy.
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. Solids, liquids and gases all expand when heat is added.

Consider the diagram of the basic structure of a bacterium. A diagram of a bacterium is labeled. Part A is the cell membrane, part B is the flagellum, part C is the nucleoid, and part D is the pilus. Which of the labeled structures in the image allows bacteria to exchange genetic material and thus evolve to be better pathogens?
Answer:
Part D: pilus
Explanation:
Conjugative pili allow for the transfer of DNA between bacteria and thus evolve to be better pathogens.
The structure in bacteria that allows them to exchange genetic material and evolve is the pili
Bacteria piliPili (pilus, singular) are thin, proteinous structures located on the surface of bacteria that serves as:
they help bacterial cells to attach to surfacesthey serve as channels for the transfer of genetic materials during conjugationWhen genetic materials are transferred through the pilus, gene recombination occurs and bacteria evolve as a result.

A group of cells that work together to perform a specialized function are called?
Answer:
tissue
Explanation:
Groups of cells working together form tissues. ... When specialized cells work together to perform a specific function, they are known as a tissue. There are four basic types of tissues: muscle, epithelial, connective, and nervous tissue.
Scientists are now studying human DNA in labs all over the world. Which are current goals for the scientists at these labs? Select three answers that apply. A. completing a full sequence of human DNA (the Human Genome Project) B. identifying the regions of human DNA that are transcribed into RNA C. identifying the regions of human DNA that bind to proteins D. analyzing the regions of human DNA that vary among individuals E. describing the molecular structure of human DNA
Answer:
B. identifying the regions of human DNA that are transcribed into RNA
C. identifying the regions of human DNA that bind to proteins
D. analyzing the regions of human DNA that vary among individuals
Explanation:
The double helix structure of the deoxyribonucleic acid (DNA) molecule was characterized and published in April 1953 by Francis Crick and James Watson. Moreover, the Human Genome Project was a project aimed at completing mapping and sequencing of the human genome. This project was completed and published in April 2003. Nowadays, scientists are focused on identifying which genes are expressed (i.e., transcribed into RNA) in specific cell types/tissues. For this purpose, it is imperative 1-to identify the promoter and enhancer regions that bind to specific proteins (transcription factors) in order to activate gene expression, and 2-to understand how genetic variation is related to gene expression patterns in specific cell types and/or in response to specific environmental stimuli.

The following diagram shows the branching tree for four kingdoms and some of their shared derived characteristics.
What shared characteristic can be written at point X? Use complete sentences to explain your answer.
Answer:Multicellular and Eukaryotic are traits that can be true for every Kingdom past Protists on this branching tree diagram. These are the traits which were evolved that Protists just missed, plants and fungi got these traits and transferred them to their descent as well.
Explanation:
A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
Answer:
Option D
Explanation:
The complete question is
A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
a) Energy was destroyed during certain steps in the experiment.
b) The steps in the experiment required more energy than was available
c) The experiments created energy that was then used up at a faster rate.
d) Some energy was transformed into unwanted heat or sound that was not detected
Solution -
Option D is correct
While transfer of energy through any medium, some energy is lost in the form of heat and light. This loss of energy is not accounted at the beginning of the process and hence the initial energy loss was zero. With the succession of the process energy kept loosing and hence the final energy count was low at all steps.

Why is it important the blood is constantly moving?
Answer:
Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell. There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy.

Why is investment in capital goods important for a country like Japan? Japan's economy depends heavily on industry and must be modern to be competitive. Japan needs investment in capital goods to develop its rich natural resources. Investment in capital goods makes up for a poor literacy rate in Japan. Investment in capital goods makes overseas trade unnecessary.
Answer: Japan's economy depends heavily on industry and must be modern to be competitive.
Explanation:
Capital goods are referred to as the physical assets which are utilized during production process and they're simply used to produce other goods. Examples of capital goods are machinery, buildings, vehicles etc.
Investment in capital goods is important for a country like Japan because the economy of Japan depends heavily on industry and must be modern to be competitive. It is a highly industrialized country and must continually invest in order to keep up with other nations.

Question: how the distance from a plate boundary affects the earthquake
Answer:
The strength of shaking from an earthquake diminishes with increasing distance from the earthquake's source.
Explanation:
So the if the strength of the shaking at the surface from an earthquake that occurs at 500km deep is considerably less than if the same earthquake had occurred at 20 km depth.
Answer:
lol , ok so the strength and the shacking of the earthquake diminishes with increasing distance from the earthquake's source, so the strength of shaking at the surface from an earthquake that occurs at 500km deep is considerably less than if the same earthquake had occurred at 20 km depth.
