Answer:

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.

Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!

Answer:

The answer is Mitochondria. I took the test and that's the correct answer.

Energy conversion within a plant cell would be limited most severely by removal of the cell's  by mitochondria.

Mitochondria are membrane-bound organelles (mitochondrial, singular) that produce most of the chemical energy required for biochemical reactions in cells.

The chemical energy produced by mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Mitochondria contain their own small chromosomes. In general, mitochondria, and thus mitochondrial DNA, are inherited only from the mother.

Therefore, Energy conversion within a plant cell would be limited most severely by removal of the cell's  by mitochondria.

Answer:

Due to isolated before mammals evolve.

Explanation:

There are many endemic plants and birds in New Zealand, but no native mammals because New Zealand is an island which isolated from Gondwana which is a supercontinent about 85 million years ago. Before mammals evolved, the New Zealand splits and go away from the Gondwana. So due to water only those mammals that can swim or fly colonized in New Zealand but not the land living mammals.

First of all, you must understand that the average life span of a person is from 70 yrs. throughout the world. See (Picture 1). Life expectancy is measured by the average of each individual who have lived inside a nation or area. It then takes into account how long they live. Was there a ongoing war affecting that area? Was there pestilence, famine, or any natural disasters? These are some examples that would affect the population of a certain demographic, and can lead to people living longer or shorter, which in turn can fluctuate the total amount in the world population. In the case of a longevity of the race of humanity, there are many things to look at.

Firstly, the ever expanding usage of the ground to furbish the energy needed for the sustainability of life. One of the many necessities that a person must meet is having access to a stable source of food, as well as water. The first part comes in the form of gathering, or finding edible food while staying away from those that are harmful. This typically came in a trial-and-error format, and gave those who survived a broader knowledge of what can be eaten, and what cannot be. The second part is the advancement of tools such as spears using flint rock, or forging of sharp wooden staves that can be used to hunt game or fish. Furbishing of meat into the diet led to people generally having more muscle strength, as well as as well as retaining muscle mass, building stronger bones and absorbing iron much more better, which is essential in blood production. Whenever there is a large and stable source of food, as well as later having a globalization trading effort, the world population would grow. Stability almost always lead to higher population growth.

Secondly, the practition of medicine and advancement in the medical field. Medicine plays an important role in not only stabilizing the homeostasis of the body, but also to prescribe a positive role in preparing the human body to develop anti-bodies to counter any new diseases (to the individual) by giving doses of weakened traits. The usage of medicine and other ways in keeping a person healthy (such as sewage systems to drain away wastes full of germs), and the advancement of medicine to negate new diseases have allowed people to survive any incidents and live longer.

Thirdly, the stability of the world (as in wars). Having smaller wars, or little to no war can affect the stability of an economic, political, and social climate of a country. The more balanced and secure it is, the more a group is willing to have children in most cases. However, that is not too say that this means that the growth rate is increasing. Stability also brings, as studies would typically show, a typical mindset for people to make more money in their early adulthood in which case to save for the future. This means putting aside finding a family, or even having kids. Marrying later typically means that the usual ages of childbearing and rearing are on it's waning stages or have already passed, in which it means that the growth is slacking. However, remember the point that I brought up that people are living longer now. This means that the world population is expanding, but not because of new population, but because of the longevity of the old. (See Graph 2).

Finally, you must understand that growth rate as a whole is not as low as expected. The growth rate can be different from country to country. Countries that typically lean towards 2nd or 3rd world countries typically still have a larger growth rate. These generally account for the large amount of world population, even though as a general rule the growth rate is decreasing in most developed countries. Take a look at the graphs shown below (picture 3 & 4). The 3rd one shows the GDP as comparable to each individual countries, which in turn typically means if the country falls under which world category.

In the end, the World Population is made up of many different individual countries, in which each experience it's own growths or set backs in population sizes. One must also take into account the movement of people through countries (typically from developing to developed) in sustaining of other places. Also, one must take into account that not only stability, but also necessity would influence a persons decision to have children, which in turn would affect the growth rate. Advancement in providing the basic necessities and health services to a person would raise the longevity, which means that while not only the population is increasing, but that the population is leaning more towards the older side then younger. Finally, the world population has a peak in limit, and that once the limit is hit, the growth rate and roof would cave the population and lower it down, typically through diseases, famine, or other natural disasters.

Answer:

The correct answer is option A ( a potentially fatal buildup of acetoacetate or 3-hydroxybutyrate lowering blood pH.)

Explanation:

Ketoacidosis results in a type of body metabolic state where the urine concentrations are high in ketone bodies, such as acetoacetic acid , 3-hydroxybutyrate. Fatty acids are converted to ketone bodies, resulting in a very high level of ketone bodies which automatically lowers the blood pH.

Ketoacidosis is of different types, Diabetic ketoacidosis, alcoholic ketoacidosis, starvation ketoacidosis. They are all associated with the accumulation of ketone bodies within the bloodstream. The underlying disease  common with ketoacidosis is Diabetes.

The statement that best describes symbiotic relationships is different species live in close associations in an ecosystem. The correct option is A.

Symbiotic relationships are those relationships in which two organisms live together and depend on each other for nutrition and space. In symbiosis, both organisms help each other.

For example, cattle and egret. The egret is a wading bird that feeds on the ticks or lice of the cattle. Eating them through the body helps clean the body of the cattle, and it also provides nutrition to the egret.

In an ecosystem, different organism lives together. Tress provides space and food for the animals. Animals help in the dispersion of seeds of various plants. In short, it is symbiosis.

Thus, the correct option is A. Different species live in close associations in an ecosystem.

wind erosion

- i know this question is older but i hope this helps anyone who may need it. :-)

The geologic process that creates an alcove is wind erosion, which is present in Option B, as the alcove is a recessed area in a rock or cliff face that is often semicircular in shape.

Alcove is created by the process of wind erosion. Over time, wind can carry abrasive particles, such as sand or small rocks, that erode the softer rock on the face of a cliff, carving out a hollow space. As the wind continues to erode the rock, the hollow can deepen and expand, forming an alcove. Alcoves are often found in areas with strong, consistent winds, such as desert regions, and can range in size from small niches to large, room-sized spaces. In addition to wind erosion, alcoves can also be created by other geologic processes such as water erosion or tectonic activity.

Hence, the geologic process that creates an alcove is wind erosion, which is present in Option B.

[tex]\boxed {\boxed {\sf C. \ Sensors}}[/tex]

Explanation:

There are two divisions of the nervous system: the central and peripheral.

The central nervous system (CNS) is made up of the brain and spinal cord. This section processes information gathered from the sensory organs.

The peripheral nervous system (PNS) is divided into the autonomic and somatic, with different functions. Regardless of the subdivision, the PNS is made up of all the nerves and sensory receptors. The nerves are connected to the brain and spinal cord, which allows them to pass information from the PNS (where it is gathered ) to the CNS (where it is processed).

So, the spinal cord (choice A) and brain (choice B) are parts of the central nervous system, not peripheral. The correct answer must be C. sensors

The female part of the flower is called gynoecium or pistil

Explanation:

The female part of a flower is called the gynoecium or pistil. The pistil is located in the center of the flower and consists of three parts: the stigma, style, and ovary.

The stigma is a sticky knob-like structure located  at the top of the pistil. It is covered with a sticky substance so pollen grains will stick to it. It is attached to the long, tubelike structure called the style.

The style is a long  long tubelike structure which connects the stigma to the ovary. The style provides the pathway through which the pollen grains will travel to the ovary in order to fertilize the eggs or ovule

The ovary is the enlarged portion of the pistil found at the base of the pistil. It contains the eggs or ovules.  After fertilization, the ovary develops into the fruit and the ovules become seeds. Based on where the ovary of a plant is located, a plant can be classified as having a superior ovary, an inferior ovary or a half-inferior ovary.
