Answer:
C. Water freezes and thaws inside rock cracks, causing them to widen and then split.
Explanation:
When water gets in the crack at the bottom and freezes, frost wedging occurs.
Frost wedging happens when water gets in crack, freezes, and expands. This process breaks rocks apart. When this process is repeated, cracks in rocks get bigger and bigger (see diagram below) and may fracture, or break, the rock.
Fair weather can usually be expected with the approach of _____.
a cyclone
an anticyclone
a low-pressure system
Answer:
Anticyclone
Explanation:
Fair weather can usually be expected with the approach of a high pressure system or an anticyclone.
Fair weather can usually be expected with the approach of an anticyclone that is present in the second option, as the anticyclone is a high-pressure system that is characterized by descending air.
What is an anticyclone?An anticyclone is a high-pressure system that is characterized by descending air, the descending air in an anticyclone is warmed by compression as because it prevents cloud formation and precipitation as it moves closer to the surface, an anticyclone typically brings clear skies, calm winds, and generally pleasant weather. A low-pressure system or cyclone is characterized by rising air, which creates an unstable and potentially stormy atmosphere, as the air rises, it cools and forms clouds, which can lead to precipitation and thunderstorms.
Hence, fair weather can usually be expected with the approach of an anticyclone, which is present in the second option.

Which of the following describes how both of these cellular division processes maintain genetic continuity?
А.Both processes involve the replication and division of identical genetic material.
B. Both processes creates cells with half the genetic material of the parent cells.
C. Both process involve the recombination and division of new genetic material.
D. Both processes create cells with twice the genetic material of the parent cells.
Answer: Both processes involve the replication and division of identical genetic material
Explanation:
During S phase interphase DNA is replicated and it is replicated as an exact copy
When a single cell divides into two cells through mitosis, genetic continuity occurs. One cell divides into two during the process of mitosis, and each of the two progeny cells has the same amount of DNA as the parent cell.
What is genetic continuity?The fact that when a cell divides, the resulting two daughter cells have the same number and type of genes as the original cell is referred to as genetic continuity. It also describes how when two sexually reproducing organisms mate, their offspring have the same number of genes as the parents. Nuclear division results in daughter cells with identical sets of chromosomes. Mitosis ensures the genetic continuity of the ancestral cells in the body's daughter cells. It consists of one fully equational division followed by a DNA synthetic phase. Because it creates a perfect copy of DNA for new cells, DNA replication helps to maintain species genetic continuity.To learn more about Genetic continuity refer to:

The weight of an object can change because of the forces acting on the object. Which force causes the weight of an object to change?
Gravity
Gravity is a force exerted by the centre of earth which pulls objects towards earth centre[tex]\\ \tt\hookrightarrow F_g=mg[/tex]
m is massg is acceleration due to gravityGravity is the driving factor behind changes in an object's weight. Gravity is the force that draws two mass-containing objects together. Gravity is the force that pushes items toward the planet's core on Earth. Hence the correct option is A.
The force with which an item is drawn towards the surface of the Earth by gravity is its weight.
An object's weight can alter if the gravitational force pulling on it changes. An object's weight will vary, for instance, if it is transferred to a location with a different gravitational field.
The weight can also change depending on how far away from the planet's or celestial body's core it is.

From which hot spot would you view Polaris at an altitude of 45 degrees?
Answer:
Massena, New York
Explanation:
Polaris is most popularly known as the North star. It is also famous by the name of "Pole Star". It is the closet to the north celestial pole. At present it is the northern pole star currently.
It is found in the constellation of Ursa Minor. It is the one of the brightest star seen in the night sky. It is considered the star of the second magnitude which is situated close to the heaven's north pole.
The altitude of the Pole star or the Polaris when an observer is at the Tropic of Cancer is measured at 23.5 degree. While if the observer sees the Pole star at its zenith, the observer is located at the North Pole. i.e. 90 degree.
And the spot from where the observer views the Polaris at 45 degree altitude is Massena, New York.

Name 2 body systems that interact to maintain
homeostasis in the human body and explain how they do
Answer:
Internal Temperatures
Similarly, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin's surface.
OR,
The nervous and endocrine systems exert the ultimate control over homeostasis because they coordinate the functions of the body's systems. Regulation of body temperature, blood pressure, pH, and glucose concentration are four examples of how the body maintains homeostasis.

In your opinion, what are the three most important molecules needed for the production of ATP? Explain your reasoning.
To produce the energy required to drive ATP synthesis, the human body requires three different types of molecules: lipids, proteins, and carbohydrate.
What molecules are required for the production of ATP?
In the mitochondria of a cell, the process of cellular respiration also results in the formation of ATP.
This can be done through either anaerobic or aerobic respiration, depending on whether oxygen is present.
ATP is produced during aerobic respiration from glucose and oxygen, along with carbon dioxide and water.
ATP hydrolysis provides the energy needed for many essential processes in organisms and cells.
These include intracellular signaling, DNA and RNA synthesis, Adrenergic signaling, synaptic signaling, active transport, and muscle contraction.
Therefore, lipids, proteins, and carbohydrate are important molecules in production of ATP.
