OB. A piece of uncovered meat that was left outside contained maggots by the end of one day.
OC. A container of soup that was heated and sealed did not grow mold even after several months.

What causes the "plastic" nature of
the asthenosphere?
A. it is mostly water
B. it only found under the ocean
C. constant earthquake activity
D. heat from below
The heat from below causes the "plastic" nature of the asthenosphere. The correct option is D.
What is asthenosphere?The asthenosphere is the upper mantle's mechanically sluggish and ductile region.
It is located beneath the lithosphere, somewhere around 80 and 200 kilometers underneath the surface, and can extend up to 700 kilometers. However, the asthenosphere's lower boundary is not well defined.
Semi-plastic rock makes up the Asthenosphere. Because of Lithosphere has a lower density, it resides on top of the Asthenosphere, much like an iceberg or a block of wood does on water.
The lower mantle beneath the Asthenosphere is stiffer and less plastic. The outer core is located beneath the Mantle.
The "plastic" essence of the asthenosphere is caused by heat from below.
Thus, the correct option is D.

what is a function of a protein marcomolecule?
Answer:
Proteins are a class of macromolecules.
Explanation:
Proteins are a class of macromolecules, that can perform a diverse range of functions for the cell. They help in metabolism by providing structural support and by acting as enzymes, carriers or as hormones. The building blocks of proteins are amino acids.
Herbivores get energy by eating plants. Plants get energy from sunlight. Why does most of the energy captured by plants never become available to herbivores?
Answer:
Because they lose most of the energy as heat when they perform metabolic activities
Explanation:
Cells of all living organisms require energy in form of ATP to perform their cellular functions. In an ecosystem, organisms obtain this energy by feeding on one another. However, these energy transfer starts from organisms capable of using sunlight called PRODUCERS e.g plants.
Herbivores, which are PRIMARY CONSUMERS get their energy by feeding on these plants. However, according to the PYRAMID OF ENERGY, which represents the flow of energy in an ecosystem, only a few portion of the energy (about 10%) derived by plants from the sun gets transferred to herbivores. This is because most of the energy (about 90%) is lost as heat when the plants undergo metabolic activities.
The majority of the energy captivated by the plants never become accessible to herbivores because of the 10 percent rule, that is, for each trophic level, only approximately 10% of the energy moves from one level to the next level.
• An animal, which primarily consume plants and its products is termed herbivore.
• The herbivores occupy the second level and consume producers, that is, the plants, thus, they are termed as the primary consumers.
• Approximately, 10% of the energy is passed from one level to the next, for each trophic level. This is known as the 10% rule.
• Due to this rule, the herbivores only get about 10% of the energy stored by the plants they consume.
Thus, due to 10% energy rule, the majority of the energy captured by the plants never become available to herbivores.

Classify photosynthesis and cellular respiration as endergonic or exergonic. Explain how you know.
Explanation:
photosynthesis is an endergonic process as it involves the absorbtion of energy (in the form of sunlight), while cellular respiration is an exergonic process as it involves the release of energy in the form of ATP molecules-the energy currency of the cell.

The examples of geological processes that occur slowly is soil erosion and weathering.
What do you mean by soil erosion?Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, and animals.
Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
Removing trees and plants, plowing fields, and overgrazing by livestock disrupts roots that stabilize sediment and soil. These human activities can increase erosion rates 10 to 100 times that of non-human geologic processes.

A man catches a disease. The man has not been immunised against this disease. A doctor gives the man a course of antibiotics. Figure 2 shows how the live number of live disease in the body changes when the man is taking the antibiotics. Four days after starting the course of antibiotics the man feels well again. It is important that the man does not stop taking the antibiotics .Explain why
Answer: To kill the bacteria causing the illness
Explanation:
When a person takes antibiotics, the bacteria causing diseases will be severely hampered in its operations which will lead to the symptoms of the disease reducing. The bacteria will not die until the drug is taken as prescribed which is why the full dosage must be taken.
If it is not, the bacteria can regain strength and start causing sickness again except this time, it may grow an immunity to the antibiotics which means that an even stronger dosage of antibiotics will be needed.

If you need to drive from Dallas, Texas, to Salt Lake City, Utah, (about 1500 miles), and the speed limit is 60 mph most of the way, what is the least amount of time you will need?
Answer:
25 hours
Explanation:
Speed is a measure of the distance traveled by a body relative to the time taken to complete a trip or a journey. Mathematically, speed can be expressed as;
speed = distance/time
Hence, time = distance/speed
The distance covering Dallas, Texas, to Salt Lake City, Utah is about 1500 miles and the speed limit is 60 mph, hence;
time = 1500/60
= 25 hours
Therefore, the least amount of time that would be needed to cover the journey is 25 hours.

25 hours is your answer

What are enzymes?Enzymes may be defined as the bio catalyst that can increase the speed of a bio chemical reaction of the body. Enzymes decreases the activation energy of the reaction and maintains the reaction equilibrium.
Wendy has investigated the rate of the catalysis of reaction at different temperatures. Enzymes are very specific in nature and works at optimum temperature conditions only. The enzyme catalyze the reaction at highest speed if the temperature is optimum for the enzymes.
Enzymes are the biocatalyst that increases the rate of a reaction without getting consumed in a reaction. They participate in the reaction and increase the rate of the reaction by decreasing the activation energy of the reaction.
The relation between the reaction rate and enzyme is shown in the following graphs. The rate of reaction is on the x-axis and the enzyme-catalyzed reaction is on the y-axis.
Therefore, As the temperature increases the enzymes gradually increase their performance until it reaches the optimum temperature.
