E)

none of the above

Answers

Answer 1

Answer:

E) none of the above

Explanation:

Mining can be defined as the process of extracting mineral resources from the Earth's surface such as seem, placer, ore-body, vein etc. Some examples of minerals that can be mined are gravel, gold, chalk, petroleum, limestone, coal, potash, rock salt etc.

The various techniques used for mining includes the following;

1. Sluicing.

2. Placer mining.

3. Hard rock mining.

4. Hydraulic mining.

Acid mine drainage can be defined as the quantity of acidic water that is being drained or flows out from a mining site.

Generally, acid mine drainage occurs when surface water infiltrates spoil banks where chemical reactions (oxidation) occur with pyrite such as iron sulphide.

Scientists build models based on what they know from previous research to derive testable hypotheses.Independently, both Watson and Crick and their competitor Linus Pauling constructed an incorrect triple-helix model with the nitrogenous bases arranged so they were on the exterior of the molecule and the phosphate groups on the interior. What evidence caused Watson and Crick to revise their model (CHOOSE 2)

Answers

Answer:

Hello. You didn't show the answer options, but we can consider that Watson and Crick revised the DNA model after seeing DNA images taken through Franklin's x-ray and by observing the pairing of the nitrogenous bases.

Explanation:

For a long time it was believed that the DNA molecule had 3 strands, instead of two, however this information was inaccurate and although defended by some scholars it was somewhat controversial and showed the need for further investigation. With that in mind, Watson and Crick decided that it was necessary to evaluate DNA in a three-dimensional way and therefore, they obtained x-ray images of DNA molecules, taken by Franklin. In these images, it was possible to notice that the DNA had two strands, instead of three. To prove this discovery, Watson and Crick analyzed the nitrogenous bases discovered by Chargaff and the way they were paired, coming to the conclusion that the DNA had two strands.

If Earthquake X measured 1 and Earthquake Y measured 3 on the Richter scale, then

A. Earthquake Y had three times the ground motion of Earthquake X.

B. Earthquake Y had ten times the ground motion of Earthquake X.

C. Earthquake Y had 100 times the ground motion of Earthquake X.

D. None of the above

Answers

Answer: C. Earthquake Y had 100 times the ground motion of Earthquake X.

Explanation:

The Richter Scale is used to measure the intensity of earthquakes by comparing them to each other. There are 10 levels to the Richter Scale and each level is 10 times more intense than the last level.

If earthquake X measured 1 on the scale and earthquake Y measured 3, then Y was (10 * 10) times the intensity of X thereby placing Y at 100 times the intensity and ground motion of earthquake X.

Most cells use a tremendous amount of ATP Multiple Choice so our bodies therefore produce and maintain a huge amount of ATP in storage. but the amount of stored ATP is not great because our body constantly generates ATP from ADP P. mainly because ATP is not very efficient as an energy currency. but only for chemical work; transport and mechanical work must use a different form of energy.

Answers

Answer:

but the amount of stored ATP is not great because our body constantly generates ATP from ADP + P.

Explanation:

When the cell needs energy the ATP present in our body is broken down into ADP and phosphorus ion. This phosphorus ion is used as a fuel for doing different activities but when there is extra phosphorus ions so this ion again combine with ADP to form ATP molecules and this cycle continues to happen in our body in order to produce energy that is necessary for our body so we can say that the quantity of stored ATP is not great due to continuous formation of ATP from ADP + P.

6.) State the principle of dominance? I

Answers

Answer:

Please find the answer below

Explanation:

According to the convener, Gregor Mendel, the law of dominance states that one allele of a gene called DOMINANT ALLELE possess the ability to mask the phenotypic expression of another allele called RECESSIVE allele.

This law explains that in a heterozygous state of a gene, the dominant allele will always be expressed over the other. For example, in the trait of height, if T is tall and dominant, it will mask the allele of the other phenotype.

Sperm goes to the vas deferens after leaving the epididymis, which is option A. Details about sperm cells can be found below.

What is sperm cell?

Sperm is the reproductive cell or gamete of the male. The sperm is responsible for the fertilization of a female gamete to form zygote.

The sperm cell is produced via a process called spermatogenesis which occurs in the testes.

The epididymis is a narrow, tightly-coiled tube where sperm are stored during maturation. However, the sperm enters the vas deferens after leaving the epididymis.

Answers

Answer:

The three basic types of adaptations, based on how the genetic changes are expressed, are structural, physiological and behavioral adaptations. Most organisms have combinations of all these types.

Explanation:

Living things are adapted to the habitat they live in. This is because they have special features that help them to survive. The development of these special features is the result of evolution due to gene mutation. These mutations aid in the survival and reproduction and passes on from one generation to the other.

Answer:

Behavioural-Physiological-Structural

Explanation:

Behavioural - responses made by an organism that help it to survive/reproduce.

Physiological - a body process that helps an organism to survive/reproduce.

Structural - a feature of an organism's body that helps it to survive/reproduce.

Desensitization is a cognitive phenomenon in which those exposed to violence tend to
A. behave more aggressively
B. become numb to more violence
C. see violence as exceptional
D savor violent iconography

Answers

Answer:

B

Explanation:

Desensitization is a cognitive phenomenon in which those exposed to violence tend to become numb to more violence.

Desensitization is a cognitive phenomenon in which those exposed to violence tend to become numb to more violence. So the correct option is B.

What is desensitization?

This is a very well-studied effect of being exposed to violence, either on-screen violence or real-life experiences of viewing violence. It is a psychological condition in which a person becomes so accustomed to violence that they don't respond the way that they did initially.

This can also be caused if a person feels like their aggressive response to violence has not caused any change in their surroundings, so now they have stopped themselves from responding at all.

Hence, a person who has been desensitized against violence would eventually stop reacting when they are exposed to more violence and will become numb.

Desensitization therapy has proven to be very effective in managing phobias where people suffering from phobias of various kinds have stopped reacting to them. But when it comes to exposure to violence, desensitization can be harmful as it would lead to the perpetuation of more violence.

Therefore, the correct option is B.
