What force is present at a divergent boundary?
A. Shearing
B. Torsion
C. Tension
D. Compression
Answers
Tension force is present at a divergent boundary. Therefore, option (C) is correct.
What do you mean by tension force?Tension is defined as the force transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the ends.
Tension formula is articulated as. T=mg+ma. Where, T= tension (N or kg-m/s2) g = acceleration due to gravity (9.8 m/s2)
All physical objects that are in contact can exert forces on each other. We give these contact forces different names based on the types of objects in contact. If one of the objects exerting the force happens to be a rope, string, chain, or cable we call the force tension.

Which structure is correctly paired with its function? (1) testis — produces nutrients for the offspring (2) placenta — allows nutrients to diffuse from the mother to the embryo (3) uterus — produces testosterone used in egg production (4) ovary — provides a place for the internal development of the embryo
Answers
Answer:
(2) the placenta allows nutrients to diffuse from the mother to the embryo.
Explanation:
The placenta is a shared organ between the mother and the embryo. It diffuses the necessary nutrients from the mother to the future baby and the residues from this one to the mother, so that she can expel them. The placenta separates the mothers and the embryo blood, but it allows the diffusion of said nutrients and wastes through especial parts of the placenta with thin walls.

A. Where is genetic material stored in the cell?
B. How many offspring can an organism have?
C. Why do different organisms live in different places?
D. Are an offspring's traits similar to those of its parents?
Answers
Answer:
The correct answer is C. Why do organisms in different places have different traits?
Explanation:
Charles Darwin was a naturalist, biologist, and geologist from England and known for his theory of evolution. According to the theory, he observed different types of species of organisms such as birds, plants and fossils all over the world and found similarities in the characteristics.
He suggested that there were variations in species on the basis of specific geological locations. On the basis of these observations, he proposed that all species of organisms are come from the same ancestor but shows the differences due to the response to the condition of their habitat or location

What is the direct cause of most earthquakes?
O Gravitational pull on bedrock by the moon
O deposition of sediment in lakes and oceans
O movement of bedrock along a fault line
O heat exchange betwęen the crust and the atmosphere
Answers
Answer:
Pretty sure it's C or B? Most likely C.
The direct cause of most earthquakes is the movement of bedrock along a fault line. Earthquakes occur when energy stored in the Earth's crust is released suddenly, causing the ground to shake. Hence option D is correct.
What is an earthquake?An earthquake is a sudden and rapid shaking of the Earth's crust caused by the breaking and shifting of rock beneath the Earth's surface. The Earth's crust is made up of tectonic plates that constantly move and interact with each other.
When these plates move against each other, they create pressure that builds up over time until the rock breaks, causing an earthquake.
This energy is released when two blocks of rock, called tectonic plates, move relative to each other along a fault.
The blocks may become stuck, and as the pressure builds up, they may suddenly slip, releasing energy in the form of seismic waves that cause the ground to shake.
The intensity and magnitude of an earthquake depend on the amount of energy released and the distance from the epicenter.
While other factors such as volcanic activity, landslides, or human activities can also cause earthquakes, movement along a fault line remains the primary cause.
Hence option D is correct.

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.
What is 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.

Explain why the world population is growing, even as the growth rate is decreasing.
Answers
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.

A cell that has 6 chromosomes in the G2 phase will have how many sister chromatids during that same phase
Answers
Answer:
12 chromatids.
Explanation:
If a cell has 6 chromosomes in the G2 phase will have 12 sister chromatids during that same phase because replication of chromosomes occurs which produces two exact copies of each chromosomes. Then 6 chromatids are distributed in one daughter cell while the other 6 chromatids are distributed in other daughter cell and finally the cell division occurs.

What is Internal structure adaptation?Any heritable characteristic that enables a plant or animal to survive and procreate in its environment is referred to as an adaptation. Individuals of a species can differ in a wide range of ways; some may be larger, hairier, better able to fend off illnesses, or even have smaller ears.
Their genes, which are inherited from their parents and later passed on to their own offspring, are mostly responsible for determining these traits.
The proportion of people who possess that favorable feature or adaptation will rise over generations until it becomes a characteristic shared by the entire species.
Therefore, Hollow bird bones is not an example of an internal structure adaptation.

Are eukaryotes more closely related to bacteria or to archaea? Explain.
Answers
Hello!
The Answer Is: Bacteria and Archaea are comprised exclusively of microorganisms; plants, mammals, and microorganisms such as fungi and protists are contained in the Eukarya. Because of their lack of a nucleus, the Bacteria and Archaea were grouped together and called Prokaryotes, but the Archaea are more closely connected to the Eukaryotes than to the Bacteria. The cell walls of bacteria contain a compound called peptidoglycan, while the cell walls of archaea do not. Archaea and bacteria also vary because the composition of the cell membranes of archaea is peculiar and does not contain the same lipids, or fats, present in other species' cell membranes.Thank you for asking this question!

Abiotic factors interact in an ecosystem.
O Saprophytes respond to abiotic changes in an ecosystem.
O Ecosystem feeding levels show changes in energy.
Answers
The statement that best describes symbiotic relationships is different species live in close associations in an ecosystem. The correct option is A.
What is the symbiotic relationship?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.
