Erosion is the process by which Earth's surface is worn away by the action of water, wind, ice, or gravity. Hence option C is correct.
Streams and rivers are agents of erosion, and they move material by a variety of processes, including:
Dissolution - The water in a stream can dissolve minerals from the rocks and soil that it flows over.
Suspension - Fine particles of sediment can be suspended in the water and carried downstream.
Traction - Larger particles of sediment can be rolled or bounced along the bottom of the stream.
Saltation - Small pebbles and stones can be bounced along the bottom of the stream.
The type of erosion that a stream or river causes depends on the size of the particles that it is carrying. Streams and rivers that carry a lot of fine sediment are called suspended-load streams. Streams and rivers that carry a lot of large particles are called bed-load streams.
Erosion by streams and rivers can have a significant impact on the landscape. It can create valleys, canyons, and deltas. It can also transport sediment to other areas, where it can be deposited and form new landforms.

20.
An amoeba divides in half.
21.
A bean plant produces seeds in long pods.
22.
Pollen grains are released from a flower.
23.
A sea star produces a new arm after losing one to a predator.
Answer:
New leaves appear on a tree in spring. - NO
An amoeba divides in half. - YES
A bean plant produces seeds in long pods. - YES
Pollen grains are released from a flower. - YES
A sea star produces a new arm after losing one to a predator. - NO
Explanation:
The appearance of new leaves has nothing to do with reproduction but rather regeneration.
An amoeba dividing in half is a form of reproduction known as asexual. Binary fission is a reproductive process in which an organism divides into two and each half develops into new independent organisms.
A bean plant producing seed is part of the reproductive process. After fertilization, the ovule of a flower becomes the seed. A seed in itself is a ripened fertilized ovule.
The release of pollen grains from the anther of a flower to the stigma of a compatible flower in the same or different individuals plants is known as pollination. Pollination is a reproductive process similar to fertilization.
A sea star producing a new arm after losing one to a predator is a regeneration process rather than a reproductive process.
If an element has 6 protons, 6 electrons, and 8 neurons, then what’s the atomic number
Answer:
The atomic mass is the number of protons, plus the number of neutrons. In this case, 8 + 6 = 14.
Explanation:
The six protons (atomic number) tells me that this is carbon; the six electrons tell me that this is a carbon atom, rather than a carbon ion (an ion is when the number of electrons does not equal the number of protons, making the atom electrically non-neutral). The eight neutrons tell me that this is an isotope (in other words, a version) of carbon called carbon-14, which happens to be mildly radioactive; and therefore useful to archaeologists in dating human artifacts.
The atomic number is the number of protons that is in the atom. If an element is having 6 protons, 6 electrons, and 8 neurons, then its atomic number will be 6, i.e. Carbon.
What is atomic number?Atomic number is the number of a chemical element as represented in a periodic system.
These elements are arranged in order of increasing number of protons in the nucleus.
The number of protons is always same as that of electrons in the neutral atom, which is also the atomic number.
Thus, here the number of protons given is 6 so the atomic number will be 6.

Which axiom is used to prove that the product of two rational numbers is rational?(1 point) Integers are closed under multiplication. Integers are closed under division. Whole numbers are closed under division. Natural numbers are closed under multiplication.
Answer: Integers are closed under multiplication.
Explanation:
Rational numbers are numbers of the form:
a/b
such that a and b are integers.
The axiom: " Integers are closed under multiplication. "
Says that if we have two integers, x and y, then:
x*y is also an integer.
So if we have two rational numbers,
a/b and c/d
Such that a, b, c and d are integers, and we multiply them, we have:
(a/b)*(c/d) = (a*c/b*d)
the numerator is a*c is the product of two integers, so this is an integer by the previous axiom.
the denominator is b*d, also a product of integers, so this is an integer.
then (a*d)/(b*d) is the quotient of two integers, then this is a rational number.
Answer:
the second one... Integers are closed under multiplication

I'm always happy to help :)You notice that your aunt, who has generalized anxiety disorder, is often restless and has trouble concentrating. Which area of her brain is most likely responsible for her responses to anxiety-provoking events? A. Amygdala B. Hypothalamus C. Anterior cingulate cortex D. Cingulate gyrus
Answer:
Amygdala
Explanation:
Generalized anxiety disorder (GAD occurs when an individual experiences excessive and continuous worry and anxiety about certain things ,It is caused by over activation of the region of the brain that mediate response to fight and flight stimulus and fear,the amygdala.
Its symptoms are difficulty with concentrations, overthinking ,indecision, irregular sleep patterns.
Two brain circuits transmitted sensory stimuli of fear or danger in the brain to two regions of the brain,
1. the peripheral cerebral cortex for voluntary decisions
2. the Amygdala for involuntary emotional decision.
The amygdala is concerned with how the body reacts to the effects of the stimuli in the immediate environments, the interactions of the stimuli with the emotions of the subject, and the involuntary response .
To respond to the stimuli of fear. The amygdala stimulates the hypothalamus.The latter activate the cardiovascular and breathing centre .Hence,adrenaline is released into the blood stream.The increases involuntary response to anxiety,which gives a fast response..The cerebral cortex response takes time to relay response.
Amygdala, stores memories of all emotions, fear, and anxiety. In patients with this disorder, the Amygdala is sensitive and had been adapted to the memory of fear and anxiety stored.Therefore, every slight normal event which should give any danger is over reacted to by the amygdala with fear or flight response, This triggers the two brain circuits to give anxiety-provoking events.
Intake of medication, Behavioural therapy are the mode of treatments.

The options are missing from the question,the missing options are;
a. Anaphylactic
b. Histamine
c. Immediate allergic
d. Delayed allergic
e. B-cell mediated.
The correct answer to the question is option D
DELAYED ALLERGIC.
Delayed allergic response is a type of late response to antigen that occurs 48-72hours after exposure to an antigen.
This type of allergic response is mediated by T-cells and macrophages.
They are otherwise known as delayed hypersensitivity response/reaction.
The response is delayed because there is sensitization upon first exposure to the antigen, therefore if there is a re-exposure,a secondary cellular response is initiated triggering the actions of the already sensitized T-cells and macrophages.

Explanation:
Shivering and vasoconstriction would be signaled to cause a: A. increase in pH. B. decrease in temperature. C. decrease in pH. D. increase in temperature.
Answer:D
Explanation: shivering occurs when someone is cold and vasoconstriction is when the blood vessels close to the skin and the veins closer to the skin surface constrict as a result of dat air doesn’t enter the body
Vasoconstriction is the narrowing of the blood vessels that hinders blood flow. Vasoconstriction and shivering will lead to an increase in the temperature through thermoregulation. Thus, option d is correct.
What is thermoregulation?Thermoregulation is the maintenance and balancing of the temperature and heat in the body. They are regulated by many factors including shivering and vasoconstriction.
During the vasoconstriction, the blood vessels close to the skin surface close and the body shivers as a result of cold or decreased temperature. This signals the body to increase the temperature so that shivering can be stopped.
Therefore, vasoconstriction and shivering signal the body to increase the temperature.
