Answer:
m=10kg h=2m Ep=mgh Ep=(10kg)(9.8 m/sec2)(2m) Ep=196J
Explanation:
The formula for potential energy depends on the force acting on the two objects. For the gravitational force, the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

What organism are tertiary (3rd level) consumers
Answer:
Third-level consumers are any organisms big enough to obtain energy by feeding off lower-level consumers. These are also called tertiary consumers. For example, in a forest ecosystem, snakes eat toads. Heron and large fish, such as bass and walleye, consume smaller fish, frogs and crayfish.
Explanation:
Answer:
The larger fishes like tuna, barracuda, jellyfish, dolphins, seals, sea lions, turtles, sharks, and whales are tertiary consumers Explanation: They feed on the primary producers like phytoplankton and zooplankton, as well as secondary consumers like fish, jellyfish, as well as crustaceans.

Which of the following statements best compares reproduction in viruses with reproduction in single-celled protists? no links please
Viruses require the cellular machinery of host cells to reproduce; single-celled protists reproduce on their own. Therefore, the correct option is (C).
Viruses require the cellular machinery of host cells to reproduce; single-celled protists reproduce on their own. The main difference between reproduction in viruses and single-celled protists lies in their reproductive processes. Viruses are obligate intracellular parasites that lack the cellular machinery required for replication. They rely on infecting host cells and hijacking their machinery to reproduce and create new viral particles. In contrast, single-celled protists are independent organisms capable of self-replication through various mechanisms such as binary fission, budding, or spore formation. They do not need a host cell for their reproductive processes. This fundamental distinction highlights the unique strategies employed by viruses and protists in propagating their species.Therefore, the correct option is (C).

How are stem cells nurtured to form a tissue/organ?
Answer:
Stem cells have the capacity to proliferate and to differentiate into relatively mature cells of various types. Embryonic stem cells can become any organ in the body and do so when implanted into a blastocyst. In principle, then embryonic stem cells could be used to replace any organ in the body.

Answer:
The P waves undergoes compression and dilation during motion in its direction of propagation. This waves reaches the station first because the P waves travels at a speed, that is much faster in comparison to the S waves. The S waves are the secondary waves and are commonly known as the shear waves.
The P waves have the ability to travel in both solid as well as in liquid, whereas the S waves can propagate only in solid region because they are absorbed at the core-mantle boundary.
Thus, the P waves will arrive the station first and the difference between the arrival of P and S waves are plotted in the graph that helps in depicting the epicenter and the amount of energy released during an earthquake.

According to urban anomie theory the impersonal nature of city life extends to situations that do not call for social involvement. Please select the best answer from the choices provided T F.
Answer:False
Explanation: right on Edge
The statement "According to urban anomie theory, the impersonal nature of city life extends to situations that do not call for social involvement" is true, as urban anomie theory suggests that the impersonal nature of city life leads to the breakdown of social bonds.
What is urban anomie theory?According to this theory, the fast pace of urban life, the diversity of populations, and the emphasis on individual achievement can lead to a weakening of social ties and a breakdown of social norms and values. As a result, individuals may feel disconnected from others and from society as a whole, leading to a sense of alienation and a lack of meaning in their lives. This sense of normlessness and detachment can extend beyond situations that require social involvement, such as interactions with neighbors or participation in community events, to other aspects of daily life.
Hence, the statement "According to urban anomie theory, the impersonal nature of city life extends to situations that do not call for social involvement" is true.

Suppose that a cell is unable to replicate its DNA. Which of the following would NOT be present in this cell? ******ONLY ANSWER IF YOU KNOW THE ANSWER GIVING BRAINLIEIST******
Answer:
sister chromatids
Explanation:
Suppose that a cell is unable to replicate its DNA, the structure that will not be present in the cell is sister chromatid.
What is sister chromatid?Sister chromatid refers to replicated chromosome that are genetically identical.
Prior to every cell division, a cell must replicate its DNA in order to have an even distribution of genetic material in the daughter cells.
The result of DNA replication is sister chromatids, which carry individual identical DNA.
Therefore, if a cell is unable to replicate its DNA, the structure that will not be present in the cell is sister chromatid.
