Weathering, erosion, and deposition are three natural processes that change the face of the Earth.
Look at the three examples below and identify which process they each represent.
Explanation:
Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion.

In terms of atomic structure, how are the elements of a periodic table group related?
If you take a look at the s-, p-, and d-block elements part of the periodic table, you'll see that they are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. And because of this, elements in the same group often display similar properties and reactivity.

The sum of the genetic traits in this population is called its V gene pooly. COMPLETE In guinea pigs, fur length is controlled by one gene. The Fallele generates long fur and the f allele generates short fur. Because only one F copy is needed to show the trait, if a guinea pig has the FF or Ff allele combination, they will have long fur. If they have the ff allele combination, they will have short fur. There is a total of 7 8 alleles in this population, There are 5 Falleles in the population. There are 3 ✓ falleles in the population. Look at the data for a guinea pig population to answer the following questions. COMPLETE Guinea pig 1: Long fur (FF) Guinea pig 2: Short fur (ff) If having long fur helps a guinea pig survive, what would you expect to see change in the population as it evolves? Guinea pig 3: Long fur (FF) DONE Cuinas nin 1. Innn fuar (Cf)
If having long fur helps a guinea pig survive, then it is expected to see the F allele is more common in the population as it evolves.
What is natural selection?Natural selection can be defined as the process of differential survival and reproduction of the fittest organisms.
The fittest organisms are life forms that have allele combinations favoring their survival and reproduction.
In this case, the F allele is an adaptive allele associated with higher fitness in the population.

What would be the finite rate of increase for a population that has leveled off at its carrying capacity(K)? (Hint: if we assume carrying capacity is 149 and the population is at carrying capacity from T9-T12, calculate the finite rate of increase).
For a finite rate of increase for a population that has leveled off at its carrying capacity the finite rate of increase will be zero (zero), Because all of the available resources have been used.
What is Population?Generally, a population is the total number of people who live in the same area. The population of a city is the number of people who live there.
In conclusion, After population has reached its carrying capacity, the finite rate of increase will be zero (zero). Because all of the available resources have been used, the ecosystem will not allow for growth.

Most water is reabsorbed from the filtrate by which region of the nephron?.
The main function of the nephron is to regulate water and other substances within the body where 67% of filtered water is reabsorbed in the proximal convoluted tubule by osmosis.
What is a nephron?It is a complex structure made up of elements such as the loop of Henle, the distal convoluted tubule, the proximal convoluted tubule, and the renal glomerulus.
Through the afferent arterioles, the blood plasma reaches Bowman's capsule, where the glomeruli are located, then the filtered fluid goes up to the proximal convoluted tube for another filtration to take place and part of the water is reabsorbed, the glucose, sodium and amino acids.
Therefore, we can conclude that water reabsorption along the nephron follows solute reabsorption and occurs in the proximal convoluted tubule by osmosis.

How do the kidneys compensate for acid-base imbalances?.
Kidneys compensate for acid-base imbalances by : Reabsorbing HCO₃ from urine back to the blood and also secreting H⁺ back to the urine.
Acid-base ImbalanceWhen the amount of acid or base produced in the human body is greater than or less than the required amount of acid or base, and the rate of excretion by the kidneys is above or below normal, the body will experience an Acid-base imbalance situation.
To correct acid-base imbalance in the body the kidney will reabsorb HCO₃ form the urine and while secreting Hydrogen ions back to the urine.
Hence we can conclude that Kidneys compensate for acid-base imbalances by : Reabsorbing HCO₃ from urine back to the blood and also secreting H⁺ back to the urine.
