Explanation:
1 to 8 km/sec- use this to work out 10 minutes
Answer:
Hi There!
Explanation:
1 to 8 km/sec
S-waves are transverse waves. Even though they are slower than P-waves, the S-waves move quickly. Typical S-wave propagation speeds are on the order of 1 to 8 km/sec. The lower value corresponds to the wave speed in loose, unconsolidated sediment, the higher value is near the base of Earth's mantle.

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.

Connect the importance between meiosis and the process of sexual reproduction. Is it possible to survive without your reproductive system? Explain.
Answer:
This can be made possible through reproductive cells undergoing meiosis since such process has specialized sex cells split and multiple after copulation. To answer the question if is it possible for a human to survive without a reproductive system, the answer is yes.

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.

22. Why do you think the sea urchin was chosen to test the effect of changes in pH?
Answer:
as it settles deeper underwater ph tends to be higher and a sea urchin tends to be more resilient to change
Acidic seawater, at current pH levels found in the world's oceans, can have a negative impact on sea urchin larval development so it is taken to test the effect of changes in pH.
What is sea urchin?Sea urchins are spiny, globular echinoderms of the Echinoidea class. The urchins were able to compensate for internal pH in modest acidification (pH 7.8) and not in higher acidification (pH 7.6).
The pH of coelomic fluid was lower at higher temperatures.
Thus, due to this, the sea urchin was chosen to test the effect of changes in pH.

Use your knowledge of osmosis to explain why the mass of each cube increased.
Osmosis passes from a medium with a high concentration of water molecules to another with a low concentration of water molecules and since the potato has low water concentration so the water transfers to it increasing its mass
The mass of each potato cube increased because they have gained water by osmosis.
Recall that: osmosis is the movement of water molecules from the region of high water concentration (high water potential) to the region of low water concentration (low water potential) through a semipermeable membrane.
A solution with a high solute concentration will have low water potential and vice versa. They are also said to be hypertonic when compared to a solution with a low solute concentration (hypotonic).
Thus, the potato cubes increased in size because the cells of the potato have low water potential when compared to the distilled water in which they were thrown. In other words, the cell sap of the potato cubes is hypertonic while the distilled water is hypotonic.

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.

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.
