3. Which of the following is NOT a method that has been used to predict earthquakes?

A) Trying to observe precursors such as foreshocks and changes to animal behavior.

B) Watching changes in weather patterns.

C) Using past earthquake patterns.

D) Predicting stress accumulation based on how recently an earthquake occurred.

Answers

Answer 1

Predicting stress accumulation based on how recently an earthquake occurred is not the method that has been used to predict earthquakes. The correct option is D.

What is earthquake?

Earthquakes typically result from subsurface rock breaking unexpectedly and rapid movement along a fault.

The seismic waves that cause the ground to tremble are brought on by this quick release of energy.

When two chunks of the ground abruptly slide past one another, an earthquake results. The fault or fault plane is the area where they slide.

Erratic animal behaviour, such as fearful or puzzled pets, or birdcalls not typically heard at night, can be a clue that an earthquake is about to happen. Water levels in wells or artesian bores suddenly change.

It hasn't been possible to anticipate earthquakes by basing stress accumulation on how recently an earthquake happened.

Thus, the correct option is D.

At which point of the ball's flight does it reach it's maximum gravitational potential energy (max potential) and maximum kinetic energy (max
kinetic)?

Answers

Answer:

Picture

Explanation:

Study Island

The points at which max potential and max kinetic energy is the last second point away from the boy is max potential and the last point is the max kinetic.

What are max potential and max kinetic energy?

The product of an object's mass (m), gravitational acceleration (g), and height is its potential energy (PE) (h). Maximum kinetic energy is the amount of energy present when both the speed and the potential energy are at their highest levels.

The boy is batting the ball and the ball went to the highest point is the max potential energy, then when the ball goes into the distance is called the max kinetic energy.

Therefore, maximum kinetic and potential energy are present at the final point and the mid or in the diagram, the 4th point respectively.

To assist in completing this question, you may reference the Animated Technique Video - Gel-Filtration Chromatography. Consider a mixture of four proteins with various molecular weights. A histone molecule weighs 15 kDa, a p53 molecule weighs 53 kDa, an actin molecule weighs 42 kDa, and an IgG molecule weighs 150 kDa. Arrange the molecules in order of their elution from a gel filtration column

Answers

Answer:

IgG molecule, p53 molecule, actin molecule, histone molecule

Explanation:

In a Gel-Filtration chromatography, the larger molecules elude faster from the gel than the small ones.

In a Gel-Filtration chromatography, there is a stationary phase and a mobile phase. The stationary phase has beads with pores. Small molecules enter the beads and descend through these beads' pores. On the other hand, large molecules do not enter the beads' pores, so they go down through the mobile phase faster than the small molecules. Since they do not have the obstacle of the pores, they descend between the beads more fluidly. As a result, the larger molecules elute first from the gel than the small molecules.

What would be a good explanation for her to give to the jury?

That at least 10 different points on the two samples matched
That the DNA profile matches someone with the suspect's hair color and skin tone
That she found one point that matched on the two DNA samples
That the DNA samples showed no clear points in common

Answers

She will give the DNA fingerprinting report to the jury which will have samples of suspect and its profile matching to the evidence found at the scene of crime.


In DNA fingerprinting hair, blood, semen, or other biological samples are required for the comparison of suspect and evidence. It depends on the unique polymorphism in their DNA.
The fragments of DNA are made to run on the electrophoresis gel and the similar bands observed will confirm the matching.
The DNA fingerprinting will provide very exact evidence if the DNA samples matched.

Hello. It is not possible to make a report of your class in the laboratory, without having attended that class. For this reason, I will show you how this report can be written. I hope it helps you.

You should start your report with an introduction. This will be a short paragraph, where you will present the laboratory where the class was held, the time and date. Then you will give a brief presentation of what was observed during that class.

In a second paragraph, you will start by explaining better, all the elements of the class, what was discussed and what equipment was used. You should also show all the activities done in the laboratory in the most detailed way possible. This paragraph can be divided into more than one paragraph, if you have a lot of information to tell.

Finally, you should end the report with a conclusion, showing what you have learned from this experience.

Human red blood cells can live from two to four months without a nucleus, and yet they continue to synthesize hemoglobin. This Group of answer choices is a chemical process that does not require continued living pathways; the red blood cells are essentially dead after they lose their nuclei. suggests that there is a low level of RNA polymeraseto degrade the mRNA. means that the necessary ribonucleases are continually translating DNA. means that both the necessary mRNAs must persist and there must be a low level of RNA-degrading enzymes present.

Answers

Answer:

means that both the necessary mRNAs must persist and there must be a low level of RNA-degrading enzymes present

Explanation:

Mature red blood cells (also known as erythrocytes) don't contain nuclei. The red blood cells that enter the bloodstream eject their nuclei in order to have more space for transporting hemoglobin, a protein whose main function is to bind molecular oxygen. Erythrocytes have a life span period of three (3) to four (4) months. During this period, the mRNA of the hemoglobin genes must remain intact in order to synthesize hemoglobin proteins (i.e., their subunits). Moreover, in mature red blood cells, the levels of the enzymes involved in the degradation of cytoplasmic mRNA (ribonucleases) must also be low to avoid bulk mRNA degradation.

Answer:

Explanation:

The Sun would be about 100 times bigger than the earth planet in the scaled-down model of the solar system because in the reality the size of sun is 109 times more than the earth so making a model more perfect and nearer to reality we have to maintain the diameter of the sun more than 100 times than the earth and other planets.

Discuss the adaptations that have enabled flowering plants to overcome the following problems associated with life on land. Be very specific in your description of the adaptations which help angiosperm survive in a land based environment as opposed to an aquatic environment. There are multiple adaptations. Study this before trying to write so that you can include a variety of features. a) The absence of an aquatic environment for reproduction. b) The absence of an aquatic environment to support the plant body c) Dehydration of the plant

Answers

Answer:

a) specialized structures and organs for reproduction (flowers)

b) lignin in the xylem

c) waxy cuticle, stomata

Explanation:

a) Angiosperms have flowers, which are specialized reproductive organs. Flowers contain specialized reproductive cells (i.e., pollen cells) which can be dispersed by wind or animals.

b) Plant tissues can be covered by a waxy cuticle that helps to conserve water and tiny pores called 'stomata' in the epidermis that close in order to prevent water loss.

c) Finally, the xylem in land plants provides mechanical support. The cell walls of the xylem are composed of lignin, an organic substance that provides structural rigidity to the plant fibers.

Answer:

A) The absence of an aquatic environment for reproduction.

Pollination.  Flowers are developed in order to reproduce, flowers help by attracting animals to pollinate (pollination aids).  Pollen for males, seed for females.  The seeds are coated with a hard outer layer to protect it.  Fruits are made so animals can it them and the seeds will spread by the means of their feces.  Seeds can be dormant for a long time.

B) The absence of an aquatic environment to support the plant body.

Roots to help hold to the ground, stems for support, vascular tissue to help hold shape, cell walls more rigid, turgor pressure.

C) Dehydration of the plant.

The cuticle was developed, a waxy outer layer found in the leaves to prevent water from leaving the plant.  Stomates control water movement, in trees scales and cork help keep water in.  Xylem transports water.
