The football has potential energy and the apple has kinetic energy.
The football has kinetic energy and the apple has potential energy.
Answer:
The football has kinetic energy and the apple has potential energy.
Explanation:
Potential energy is the energy of an object at rest. Because the apple is hanging from a tree, it is not moving. Therefore, it has potential energy.
Kinetic energy is the energy of an object in motion. Because the football is moving from being in the air to hitting the ground, it has kinetic energy. When it hits the ground, the kinetic energy gets transferred into the ground.

Determine whether the given procedure results in a binomial distribution (or a distribution that can be treated as binomial). If the procedure is not binomial, identify at least one requirement that is not satisfied. The YSORT method of gender selection, developed by the Genetics & IVF Institute, was designed to increase the likelihood that a baby will be a boy. When 150 couples use the YSORT method and give birth to 150 babies, the genders of the babies are recorded. Does the procedure represent a binomial distribution? A. No, because there are more than two categories for each trial. B. No, because the trials of the procedure are not independent. C. Yes, because the procedure satisfies all the criteria for a binomial distribution. D. No, because the probability of success differs from trial to trial.
Answer:
The correct answer is C)
Explanation:
The number of couples who used YSORT method (x) = 150That is, the number of couples who used YSORT method is limited or defined or definite.The probability of giving birth to a boy, for each couple is 1/2 or 0.5The gender of the baby born in each case mutually exclusive (Independent)
We can conclude that the procedure results in a binomial distribution because the assumptions of the binomial distribution are met.

The number of chromosomes during meiosis is incredibly important.why is that?
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes, Meiosis also produces genetic variation by way of the process of recombination.
I hope this helps you
Meiosis refers to the process by which a single cell divides twice to produce four haploid daughter cells. These are the gametes, which are sperms in males and eggs in females.
Why the number of chromosomes is important during meiosis?Meiosis is a eukaryotic cell division process. However, the genetic material distributed among the resulting daughter cells is distributed in very different ways by these two processes.
Mitosis results in the formation of two identical daughter cells, each with the same number of chromosomes as the parent cell.
Meiosis, on the other hand, produces four distinct daughter cells, each with half the number of chromosomes as the parent cell.
Because meiosis generates cells that will become gametes (or reproductive cells), this reduction in chromosome number is critical; without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.
Thus, we can conclude that the number of chromosomes during meiosis is incredibly important because It allows gametes to have half the original number of chromosomes of the organism.

The fuel for nuclear power plants comes from
Answer:
Most nuclear reactors are fueled with a compound known as uranium dioxide. This uranium dioxide is put together in a fuel assembly and inserted into the nuclear reactor—where it can stay for several months or up to a few years. While in the reactor the fuel undergoes nuclear fission and releases energy
Explanation:
Answer:
Uranium is the most widely used fuel by nuclear power plants for nuclear fission. Nuclear power plants use a certain type of uranium—U-235—as fuel because its atoms are easily split apart. Although uranium is about 100 times more common than silver, U-235 is relatively rare at just over 0.7% of natural uranium.
Why do droughts contribute to desertification?
Answer:
Drought and desertification are firmly related phenomenon. Continuing over months or years, drought can influence enormous zones and may have genuine ecological, social and financial effects.
While drought is a characteristic phenomenon, whose effects can be exacerbated by human exercises that are not adjusted to the neighborhood atmosphere, land debasement is the way toward transforming fruitful land into less or non-gainful land. In extraordinary cases in drylands this is called desertification.
Land debasement and desertification are complex phenomenon driven by un-adjusted human action in mix with land and climatic requirements. Improper land use, for example, monocultures, and unreasonable land the board rehearses, for example, deforestation, unsatisfactory agrarian practices and overexploitation of water assets), can cause land debasement that can be additionally disturbed by drought.

The truth about the last ice age: D. There was now a submerged overpass.
An ice age also called an ice age, is a geological period in which thick ice sheets cover vast land areas. These massive ice ages could last for millions of years and could radically change the surface topography of entire continents.
There have been several major ice ages in Earth's history. The amount of sunlight reaching Earth over thousands of years varies considerably, especially at the North Pole and its surrounding northern latitudes. When less sunlight reaches northern latitudes, temperatures drop, more water freezes into ice, and the Ice Age begins. This ice age began about 2.6 million years ago in a period known as the Pleistocene epoch and lasted until about 11,000 years ago. Like everything else, the Last Ice Age brought about a series of glacial advances and retreats. In fact, we are technically still in the Ice Age.
