d. a loss of electrons
Answer:
object x and object y are rubbed together. object x acquires a negative charge, what does object y experience?
a. a gain of protons
b. a loss of protons
c a gain of electrons
d. a loss of electrons
Explanation:
:) answer mom
The charge of object y will be positive since it will have excess proton and less electron.
What is positive charge?A positive charge is obtained when an atom losses its electron usually a metal. It simply defines the excess of proton in an atom or deficient of electron in an atom.
If object x acquires a negative charge, then object y must have supplied the excess electron to it.
Thus, the charge of object y will be positive since it will have excess proton and less electron.

rashid is conducting a seminar on the importance of coral reefs which point should he include
Answer:
Protect coastlines from storms, erosion and provide habitat.
Explanation:
Coral reefs protect coastlines from storms and erosion as well as provide a habitat for thousands of aquatic animals. These points rashid must include in his seminar. Coral reefs are very important for the marine ecosystem because it can save the soil from erosion and decreases the intensity of storms by acting just like barrier. It provides food as well as living place for many organisms so these point are very important to be included in the seminar.
Answer:
that corals provide economic assistance to coastal populations through fisheries

Over time, a series of random occurrences can cause an allele to become more or less common in a population. This is called . When a population is severely reduced by an environmental disaster such as a fire, the result is a due to the reduced genetic diversity of the survivors. 3. The can occur if a small group of organisms migrates to a new location and becomes isolated from the rest of the population.
Answer:
Over time, a series of random occurrences can cause an allele to become more or less common in a population. This is called Genetic drift.
When a population is severely reduced by an environmental disaster such as a fire, the result is a Bottleneck effect due to the reduced genetic diversity of the survivors.
The Founder effect can occur if a small group of organisms migrates to a new location and becomes isolated from the rest of the population.
Explanation:
Genetic drift is an evolutive force. It is the random change that occurs in the allelic frequency of a population through generations. Its effects are harder in a small-sized population, meaning that the magnitude of this change is inversely related to the size of the original population.
Genetic drift results in some alleles loss -including the beneficial ones-, while some other alleles get fixated. Low-frequency alleles are the most likely to be lost. The changes produced by genetic drift accumulate in time and results in a loss of genetic variability within a population.
Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure -bottleneck effect- or because of a population split -founder effect-. The bottleneck effect most likely affects smaller populations.
The bottleneck effect -a case of genetic drift-, mostly affects smaller populations after the occurrence of a natural disaster or some human action -such as extensive hunting, for instance-. These events might act as a pressure that reduces significantly the number of individuals in a population. In these situations, some alleles are lost, and the survivors have a different genetic charge than the one of the original population. There might be a reduced genetic variability, with a possibility of developing a peculiar allelic component. If the survivors in the population carried or developed a mutation, probably this mutation passed from generation to generation. Founder effect refers to the origin of a new population from only a few individuals that are coming from a bigger-sized population. These founder individuals, which are carrying some of the genes of the original population, settle down in a new area and reproduce. The new and small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be lost by complete. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced, and there exists the possibility of developing a peculiar allelic composition. When the number of individuals that originated the new population is low, the founder effect will be very extreme because the genetic drift effects are inversely proportional to the original number of individuals.Can anyone help p,ease

HELP! A 20-kg bag of rice dropped from an airplane. What is the gravitational force on the bag? Acceleration due to gravity is 9.8 m/s/s.)
10.02 N
19.6 N
20.8 N
196 N
Answer:
20.8
Explanation:
I took it and it was right
196N is the gravitational force on the bag. So, the correct option is D.
What is gravitational force?Any two items in the universe can be attracted to one another by the gravitational force. All mass-containing objects are drawn towards one another by this attraction, which also keeps the moon in its orbit around the Earth and the planets in their orbits around the sun.
The mass of the two objects and their separation determine the gravitational force's strength. The force of gravity between two objects is directly proportional to their masses and inversely correlated to the square of their distance, according to Newton's law of universal gravitation.
The gravitational force on the bag can be calculated using the formula:
force = mass x acceleration due to gravity
Plugging in the given values, we get:
Force = 20 kg x 9.8 m/s/s
Force = 196 N
Therefore, the correct option is D.

Answer:
A. It would contaminate the land and water with dangerous poisons
Explanation:
Putting medical and chemical waste into landfills has extremely dangerous consequences to the environment and public health.
If they were put into landfills, these toxic wastes would leech into the soil and groundwater below them.
These toxins can accumulate over time, and harm plants and animals.
Humans may also absorb these toxic chemicals.
So, the correct answer is A. It would contaminate the land and water with dangerous poisons
Answer:
A
Explanation:
The water and land will become contaminated which will harm or endanger all the living organisms and us humans around it. Because they use the water and land source.
