Which term is defined as masses of rock,earth and/or debris that flow downhill.
A.tsunami
B.aftershock
C.liquefaction
D.landslide
Answer:
The term that defines masses of rock, earth and/or debris that flow downhill is landslide (option D).
Explanation:
When a landslide occurs, a certain amount of the mass of earth is detached or displaced downwards, due to the instability present in a certain area, especially when there is a slope in that land or slope .
The area that is unstable is usually in proximity to a stable ground zone, over which the slide occurs. The instability produced by the phenomenon is due to the fact that this ground has reached its maximum tangential tension.
In a landslide, the movement of rocks, debris and everything in the strip of land that slides can also be observed.
The other options are not correct because:
A. Tsunami is the term for tidal wave, which impedes the displacement of large bodies of water, like waves, that reach the continent.
B. Aftershock is the term that defines the seismic movements after an earthquake.
C. Liquefaction of the earth implies that a compact terrain loses strength and becomes semi-liquid.

Explanation:
explain why a fresh wound on the skin bleeds more on a hot day than a cold day
Answer: This is more of a guess based on what I already know about liquid in certain temperatures but I would say it would have to be related to the blood having a harder time congealing due to the molecules moving faster because of the temperature. You probably already know that atoms move faster in higher temperatures as opposed to cooler ones, therefore the process of congealment and essentially transitioning from liquid to solid would be easier/quicker in cooler temperatures where the atoms in and around the wound would be moving slower.

2. A unique characteristic of the banyan tree is that roots grow down from its
branches into the ground. The tree can appear to have several trunks. What
advantage does this root characteristic give the banyan tree over other trees?
A. The roots provide shelter for ground-dwelling animals, which carry nutrients
to the tree.
B. The banyan can grow near the equator, because aboveground roots are
more protected from the sun.
C. The banyan can only grow in humid climates, because aboveground roots
are more likely to dry out and die during droughts.
D. The banyan can grow in areas prone to hurricanes and typhoons because
the roots make the tree more stable in high winds.
Answer:
D. The banyan can grow in areas prone to hurricanes and typhoons because
the roots make the tree more stable in high winds.
Explanation:
According to this question, banyan tree posseses a unique characteristic in which roots grow down from its branches into the ground making the tree appear to have several trunks. This type of root is called STILT OR PROP roots.
The major function of this stilt roots is to provide additional support for the plant during adverse conditions. Hence, a major advantage that this root characteristic give the banyan tree over other trees is that it confers resilience upon the banyan tree, making it able to grow in areas prone to hurricanes and typhoons because the roots make the tree more stable in high winds.

Which of these most likely caused the cavities in the land surface?
shifting of tectonic plates
dissolving of rocks by groundwater
lack of water during long periods of drought
breaking up of rocks due to high temperature
Answer:
I think is B as well.. c:
Explanation:
These crevices frequently appear when a construction crew buried organic waste, including tree branches, brush, stumps, and building supplies. Thus, option B is correct.
What caused the cavities in the land surface?Rainfall that seeps through the soil absorbs carbon dioxide and combines with decomposing vegetation to produce water that is just a little acidic.
This subsurface water progressively dissolves limestone while forming a network of holes and cavities as it travels via fissures and cracks.
After a few years, the degradation of this buried waste produces a sizable underground void that is concealed by a thin layer of flora and soil.
Sinkholes can be created when water from a damaged pipe seeps through mud and rocks and erodes the ground below.
Therefore, dissolving of rocks by groundwater caused the cavities in the land surface.

Write and discuss brifely the basic application and implication areas of major branchs of psycology
Answer:
Psychology is the academic discipline concerned with the inner life (knowing, feeling and striving) and the behavior of people. It generally does this by following the scientific method, but in some cases it makes use of symbolic interpretation and critical analysis, following the example of other social sciences.
The goal of psychology is to acquire knowledge about the behavior of humans, both in their everyday environment and under special circumstances. With the emergence of the behavioral movement, the object of psychology was reduced to the outwardly observable and measurable behavior of animals humans, because the inner life would not be objectively registered by scientific observation, but only subjectively by introspection and understanding. This limitation has been reversed, among other things by the 'cognitive revolution' in psychology, by the great social importance of psychotherapy and by the connotations that the word 'psychology' evokes in everyday language use.

In her report of an investigation, shira states that the height of a bush is 0.65 meters. Nathaniel states that the height of the same bush is 65 centemeters. How do the statements of the two students compare?
Answer:
See the answer below
Explanation:
The statements of the two students are the same, just that they used different units for the height.
100 centimeters is equivalent to 1 meter
65 centimeters would be equivalent to 65 x 1/100
= 0.65 meters
Hence, 0.65 meters and 65 centimeters are the same height but with different units.

In what stage are humans learning essential skills like hunting, cooking and animal identification
Adult
Childhood
Adolescence
Infancy
Answer:
Adolescence
Explanation:
Given that infancy, age is the age of little children from the point of birth to about four years
Hence, this cannot be an answer.
Childhood is wrong because the childhood age is the age of 2 to 13. At such a tender age, one cannot go hunting due to fear of wild animals or have the capacity to learn to cook different food
Adult is also not correct because Adult age lies between 21 to 40 when middle age comes by. At this stage, one is expected to have at least basic skills to survive.
Therefore the correct answer is Adolescence. This is the age of 10 to 19. It is the last stage before Adulthood where one has to hone his basic and surviving skills. At this point, it is believed one has full mental capacity.

Answer:
I think its c ?
Explanation:
amino acids form with peptide bonds in order to make a chain kind of, that's the easiest way to explain that
The best description that how proteins form is amino acids form peptide bonds. Thus, option C is correct.
What are the types of amino acid?The three amino acids, lysine (Lys), arginine (Arg), and histidine (His), on the other hand, are regarded as basic amino acids. These amino acids are classified as basic because they include basic amine groups (-NH2) in their side chains that can accept a hydrogen ion (H+) from the environment. It is significant to remember that amino acids can become more basic or acidic depending on the pH of the surroundings.
Aspartic acid (Asp) and glutamic acid (Glu) are the two amino acids that are regarded as acidic amino acids. These amino acids are acidic due to the Carboxylic acid group (-COOH) in their side chains, which has the ability to donate a hydrogen ion (H+) to the environment.
Therefore, The best description that how proteins form is amino acids form peptide bonds. Thus, option C is correct.

In addition, it prevents the breakage of containers with chemical or biological products, which could contaminate the work area or cause damage to the scientist.
Question 2
In this part of the experiment, you’ll prepare and test three milk solutions: milk and water, milk and lactase enzyme, and milk and heated lactase enzyme.
Prepare
Use masking tape to label the three beakers: “milk,” “lactase solution,” and “heated lactase solution.”
Measure 60 milliliters of milk in the graduated cylinder (or ¼ cup of in a measuring cup. Pour it into the beaker labeled “milk.”
In the beaker labeled “lactase solution,” add one lactase tablet and 100 milliliters (or 1/2 cup) of cool or room-temperature water. Use the stirrer to dissolve the lactase tablet in the water.
Add 100 milliliters (or 1/2 cup) of milk to the microwaveable container. Dissolve a lactase pill in the container. Put the solution in the microwave and heat it to boiling (about 2 minutes). Use oven mitts to remove the container. Pour the heated lactase solution into the beaker labeled “heated lactase solution” and let it cool.
Stay safe! Be careful while handling the boiled mixture to avoid spilling it on your hands.
Test
While you’re waiting for the lactase solution to cool, read the directions on the test strips. The test strips in the Edmentum lab kit will react to glucose within a few seconds. If you use different strips, the reaction time may vary. Now follow these steps to test the solutions. Record your data in the answer space.
Milk and water solution: Fill the first test tube one fourth full of milk. Fill the small graduated cylinder with water and gently add it to the milk in the test tube until the test tube is half full. Use the stirrer to thoroughly mix the solution. Then insert the test strip for 10 to 20 seconds. Look at the test strip, and record whether it changed color. Wash the stirrer.
Milk and lactase enzyme solution: Fill the second test tube one fourth with milk and one fourth with the lactase solution. Use the stirrer to thoroughly mix the solution. Insert the test strip for 10 to 20 seconds, and record whether it changed color. Wash the stirrer.
Milk and heated lactase enzyme solution: Fill the third test tube with one fourth milk and one fourth of the heated lactase solution. Use the stirrer to mix the solution. Insert the test strip for 10 to 20 seconds, and record whether it changed color.
Note: Keep the lactase and heated lactase solutions for the next part of the experiment.
Wash the “milk” beaker, the test tubes, and the stirrer. If you used paper cups as an alternative, throw them away.
Answer:
The bacterium should stop production of lactase.
Explanation:
This is because the E. coli bacteria can degrade lactose, but lactose is not preferred as source of fuel or energy to glucose. If glucose is present, E. coli would preferably employ it over lactose as Glucose needs little process and minimal energy to degrade when compared to lactose. Although, if lactose is the major sugar that is present, the E. coli will have no option than to employ it as it's source of fuel or energy. The formation of lactase enzyme utilizes energy, which cannot be utilised in the presence of high level glucose.
This appears to be a set of instructions for a lab experiment involving testing different milk solutions with lactase enzyme.
What is lactase enzyme?Lactase is an enzyme that breaks down lactose, a sugar found in milk and dairy products, into glucose and galactose. People who are lactose intolerant have insufficient levels of lactase, which can lead to symptoms such as bloating, gas, and diarrhea when they consume dairy products.
The experiment involves preparing three different solutions (milk and water, milk and lactase enzyme, and milk and heated lactase enzyme) and then testing each solution with a test strip to see if it changes color, indicating the presence of glucose.
The instructions also include safety precautions, such as being careful while handling the heated lactase solution. Finally, the instructions remind the reader to wash all equipment used in the experiment.
Some people may have lactose intolerance, which means that they do not produce enough lactase to break down lactose in their bodies, resulting in discomfort and digestive problems.

The plants stand still, are not very physically active, and seem to be on the menu of many animals. Precisely because they cannot win at the first sign of danger, one has developed other ways in which they can defend themselves from annoying and dangerous animals.
Some have developed long thorns that repel attackers. Some have poisons that are very strong and because of which animals do not think of trying to eat that plant, but the defense of some plants seems to be well thought out and ready for all forms of attack.
