Answer:

B. Reverse

Explanation:

A hanging wall and footwall are present in every fault that is inclined from vertical. In reverse type of fault is the hanging wall above the footwall. Therefore, option B is correct.

The higher or overlaying block along the fault plane is referred to as the hanging wall, or headwall, and the block below is referred to as the footwall as rocks slide past one another during faulting. The direction in which the fault plane and Earth's surface collide is known as the fault strike.

The rock above the fault zone in a cross-section view of a fault is referred to as the hanging wall.The foot wall refers to the rock beneath the fault zone.

Consider digging a mine along the fault line to help you distinguish between the two. The footwall is the brick directly beneath your feet, and it is also the one on which you would hang your miner's lantern.

Thus, option B is correct.

Answer:

may cause negative side effects

Explanation:

Answer:

May cause negative side effects.

Explanation:

I took the test

Genetic Engineering is used to put genes from one organisms into another. The new organism can reproduce. And while it may seem like it's the answer the nutrition value and scarcity of food is in no way impacted. It's not like cloning. Where more are being created in large amounts with similar diets. They can be cross-pollinated with organisms with different diets. So the only obvious answer would be the negative side effects.

Answer:

Hershey and chase sought to determine if the replicating piece of phages that entered bacteria during infection, the genetic parts, were solely DNA.

Explanation:

Answer:

The process through which creatures evolve is known as evolution. Mutations cause genetic variety throughout populations, and the ecosystem works with this diversity to select people who are most suited to their surroundings. Eventually, a species can develop into a plethora of others; as a theory suggests that sapiens started as monkeys but evolved into the humanoid beings that we are today. In biology, adaptation is the procedure where a species fits to its habitat; it is the outcome of natural selection acting on hereditary diversity over numerous generations. Survival the fittest is a saying that suggests the fittest survive, not the weak. This is commonly seen in everyday life, whether with humans, animals, plants, it holds the same meaning. An example would be that a person in better physical and mental health would go farther and live longer than one with weak physical and mental health.

The concept of "survival of the fittest" is a key tenet of evolution, which refers to the idea that individuals with traits that provide them with a competitive advantage in their environment are more likely to survive and reproduce than those without these traits. This process of natural selection leads to the gradual accumulation of beneficial traits in a population, resulting in adaptation and evolution over time.

Adaptation refers to the process by which organisms develop characteristics that allow them to better survive and reproduce in their environment, such as camouflage or the ability to digest new types of food.

Evolution refers to the broader process of change over time in a population's genetic makeup and physical characteristics, resulting from the interaction between genetic variation, natural selection, and other factors. Together, these concepts help explain how organisms are able to adapt and change over time, resulting in the diversity of life that we see today.

The study of evolution has important implications for understanding the history and development of life on Earth, as well as for addressing modern challenges such as biodiversity loss and climate change.

Short paragraph:

Homeostatis is the process by which the body maintains a stable internal environment. The hypothalamus is a part of the brain that regulates many key body processes. It works to restore the system to its normal state when an internal change in one of these systems occurs.

Long paragraph:

The hypothalamus is a part of the brain that regulates many key body processes including internal body temperature, hunger, thirst, blood pressure, and daily (circadian) rhythms. When the brain receives signals from the body about an internal change in one of its systems, it works to restore the system to its normal state. For example, the normal internal temperature for the human body is approximately 98.6 degrees Fahrenheit. If the body temperature rises because of exercise, the body will try and cool itself off. This happens through coordination between the hypothalamus and the various body systems that are affected.

Explanation:

Answer:

When plants are growing, photosynthesis outweighs respiration. As a result, plants take more CO2 out of the atmosphere during the warm months when they are growing the most. Levels of carbon dioxide in the atmosphere rise and fall each year as plants, through photosynthesis and respiration, take up the gas in spring and summer, and release it in fall and winter. Now the range of that cycle is expanding as more carbon dioxide is emitted from burning fossil fuels and other human activities.

All the options are true statements  regarding the glycolysis and its mode of

operation.

Glycolysis involves the breakdown of glucose in order to release energy.

This produces pyruvate, two hydrogen ions , two molecules of water and

the free energy is used to produce ATP

In glycolysis, electrons and hydrogens get removed from glucose when it

gets oxidized and then they get transferred to NAD+, making NADH.

The ATP is generated by the transfer of a phosphate to the ADP to form ATP

which is a source of energy.
