Match each type of stress with its description.
stress caused by rocks pulling apart
compression
stress caused by rocks being pushed in
opposite directions
tension
stress caused by rocks pushing together
shearing
Correct!
Answer:Shearing: stress caused by rocks being pushed in opposite direction
Tension: street caused by rocks pulling apart
Compression: stress caused by rocks pushing together
Explanation:
Matching the description with each type of stress associated with rocks, we have:
1. Tension: street caused by rocks pulling apart.
2. Shearing: stress caused by rocks being pushed in opposite direction.
3. Compression: stress caused by rocks pushing together.
A rock can be defined as a solid naturally occurring landform that is made up of minerals.
In Geology, stress can be defined as a force that acts on a rock per unit area.
Generally, there are four (4) main types of of stress associated with rocks and these include:
1. Tension: it is a stress typically caused by rocks pulling apart, which makes them to either increase in length or break apart.
2. Shearing: it is a stress typically caused by rocks being pushed in opposite direction due to the effect of parallel forces.
3. Compression: this is a stress that is caused by rocks pushing together, which makes them to either fold or fracture (break).
4. Confining stress: it is a stress typically caused by rocks being pushed down by the weight of any material above it.

In the energy pyramid, the snake is classified as a
A)
consumer
B)
decomposer
herbivore.
D)
producer.
In the energy pyramid, the snake is a consumer. Therefore, the correct statement is option A.
What is a food chain?A food chain is a series of organisms in an ecosystem where the energy flows from one organism to another organism and each organism serves as food to another organism. For example, plant is consumed by herbivore. The herbivore is then consumed by a secondary consumer, which is in turn consumed by a tertiary consumer.
In an energy pyramid provided, the snake is classified as a consumer. Consumers are organisms that consumes other organisms to obtain energy. Snakes are carnivorous animals that consume other animals, such as rodents, birds, etc. Therefore, they are consumers in the energy pyramid.
Decomposers are organisms that feed on dead organic matter, while herbivores are animals that consume only plants, and producers make their own food.
Therefore, snake is a consumer in the energy pyramid.

Typically, screws and bolts are made from steel due to its strength and relatively inexpensive cost. However, screws and fasteners can also be produced from stainless steel, brass, titanium.
To measure the diameter of screws and bolts, you measure the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.

Explanation:
Predators usually prey upon sick animals so that the best among the specie is able to reproduce and produce the most fertile offspring. This maintains the cycle of nature. If too many predators are killed, it will cause sick animals to live longer. As a result, they will reproduce and the offspring will not be healthy enough which in future, can cause many problems.

~AH1807How did Watson and Crick learn about Chargoff's rules?
Answer:
Chargaff explained his findings and research to Watson and Crick at Cambridge.
Explanation:
Watson and Crick met Erwin Chargaff at Cambridge in 1952, where he explained his research and findings to them. His rule of parity, or 1:1 rule, stemmed from his discovery of guanine's equal ratio in pairing with cytosine.
Watson and Crick went in to use Chargaff's findings and the work of the researcher Rosalind Franklin as a basis for their work on DNA's double-helical structure.
2. In some dogs the allele for barking is dominant to the allele for non barking. How would a breeder get a strain of pure breeding barkers? Assume he has males and females of both types.
Answer:
Explanation:
Dominant traits are traits that are visible in the phenotype of an organism.
If barking is dominant in some allele of the dog and it has both male and female then a cross between the male and female with the dominant allele for barking will give a strain of pure breeder barkers.
A recessive allele cannot breed a pure barker because it does not have the allele for barking.
Hence a cross between two individual that dominos of the allele will breed true type.
Which of the following is not a way that the environment can influence traits?
the presence of toxins in the environment
through epigenetic factors
expression of the dominant trait
through variation in temperature
Answer:
The correct answer is - expression of the dominant trait
Explanation:
The ineraction of the genes such as dominant and recessive trait are incorporated in the genes and not influence by the environmental condition. These interaction are by the de noo mutations or due to the error in gene expression.
The environmental conditions like toxins cause alteration or mutation in the gene expressions. Temeprature or epigentic conditions are also the factor the can cause influence to traits.

The statement that best illustrates how an organism maintains homeostasis is as follows: desert plants close the pores on their leaves during the day to reduce water loss (option A).
What is homeostasis?Homeostasis is the ability of a system or living organism to adjust its internal environment to maintain a state of dynamic constancy; such as the ability of warm-blooded animals to maintain a stable temperature.
Homeostasis is a very important process in ensuring the survival of an organism. It is the way that living organisms regulate their internal environment despite the changing external environment.

What is pseudoscience?Pseudoscience is a proposition, a finding, or an explanation system that is presented as science but lacks the rigor required by the scientific method.
Pseudoscience can also result from research that is based on flawed premises, a flawed experimental design, or poor data.
Astrology has not been proven effective in controlled studies, has no scientific validity, and is thus considered pseudoscience.
The main distinction Popper draws between science and pseudo-science is one of attitude.
A pseudo-science is set up to look for evidence that supports its claims, whereas a science is set up to challenge its claims and look for evidence that may prove it false, according to Popper.

Which of the following is true for gravitational force
Answer:
B increases with increase in mass
Explanation:
Like most students, Megan really enjoyed doing labs in science class. One day her teacher allowed the class to design their own experiment. Her task was to see if she could blow up a balloon using chemicals. Megan knew that vinegar and baking soda would fizz and produce a gas. However, her teacher didn't give her any vinegar to use, only dilute hydrochloric acid. Megan thought she could use the acid in place of the vinegar.
Based on the reading above, which hypothesis would be supported by the experiment?
The BALLOON BLOW UP SCIENCE EXPERIMENT provided evidence to support this claim.
When baking soda, a basic, and vinegar, an acid, are combined, a chemical reaction occurs that produces carbon dioxide gas. Instead of having a predetermined volume or shape, gases expand quickly to fill their container. Because of the fast particle motion in all directions, gases expand quickly. The carbon dioxide gas starts to fill the balloon as it fills the bottle since it has nowhere else to go. The balloon fills with carbon dioxide gas and expands as a result. The size of the balloon will increase with the amount of gas produced. A material is said to be acidic if it has a bitter taste, reacts with metals and carbonates, and turns blue litmus paper red. A base is a compound that has a bitter taste, is slick to the touch, and causes red litmus paper to turn blue.
