A) They are formed by weak streams, slowly wearing away rock over time. B) They are formed by forceful streams, cutting down into rock over time. Eliminate C) They are formed by massive mountain glaciers slowly moving down slopes. D) They are formed by forceful winds moving between the walls of the valley.
Answer:
The answer is B
Explanation:
In the picture there is 2 streams also I took the question myself for you and the answer was B.
This type of valley is typically firmed by forceful streams cutting down into rock over time. So the correct option is B.
What is a valley?Valley: an extended depression on the surface of the Earth. Rivers are most often responsible for draining valleys, which can be found on relatively level plains or in between groups of hills or mountains. Rift valleys are those valleys created by tectonic activity. Gorges are the name given to similar-looking, extremely deep, narrow valleys. Despite being possible in different geological contexts, both of these latter kinds are frequently cut in strata with a flat topography.
There is potential for the land surface to develop into the well-known patterns of hills and valleys wherever there is enough rainfall. In fact, there are hyperarid regions with little activity. There are also geomorphological conditions where water cannot concentrate on the ground surface due to the permeability of the rocks or sediments causing excessive infiltration.
Therefore the correct option is B.

Climax community- most stable community that takes hundreds of years to develop. The types of organisms change due to __?__.
competition
random chance
being the luckiest
Answer:
competition
Explanation:
An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).
A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.
Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.
PLS ANSWER How is sunlight important in your life? Describe some of the positive and negative effects of sunlight.
Answer:
Sunlight is important in my life because you need it if you have a plant and you want to take care of the plant.Postive effects of sunlight is Sun water and needing health
Answer:
I know one reason is that plants need sunlight, and without plants we would all die. This is because plants need sun, and if we didn't have plants, we would be robbed of that resource, and then animals who eat the plants would die, so meat would be taken from us as well and we would all DIE.
how are organisms in the domain archaea different from those in the domain eukarya?
a: archaea are multicellular organisms
b: archaea hold genetic information in DNA
c: archaea have no membrane around their organelles
d: archaea have mitochondria inside their cells
Organelles in the domain of Archaea do not have membranes surrounding them, in contrast to those in the domain Eukarya. So, the correct option is C.
What are Archaea?The realm of single-celled organisms is called Archaea. These microbes are prokaryotes because they lack cell nuclei. The term "archaebacteria," which was used to describe archaea when they were first categorised as bacteria, is no longer in common usage.
Single-celled microorganisms known as archaea lack membrane-bound organelles and a cell nucleus. Archaea, like other living things, have a semi-rigid cell wall which shields them from their surroundings. Organelles in the domain of Archaea do not have membranes surrounding them, in contrast to those in the domain Eukarya.
Therefore, the correct option is C.

Explain the movement of ribs during inhalation and exhalation.
Answer:
Inspiration (breathing in)
The diaphragm contracts and moves downwards. The intercostal muscles contract and move the ribs upwards and outwards. This increases the size of the chest and decreases the air pressure inside it which sucks air into the lungs. During normal breathing, the major inspiratory muscles produce rib cage expansion and a downward movement of the diaphragm. These movements cause the pressure around and in the lung to become negative (relative to atmospheric pressure).
Explanation:
Explanation:
During normal breathing, contraction of the major inspiratory muscle, the diaphragm, produces both rib cage expansion and a downward movement of the diaphragm. These movements cause the pressure around and in the lung to become negative relative to atmosphere.
Low frequency waves:
A. have high amplitudes.
B. Have long wavelengths.
C. Travel at high speeds.
D. Have short wavelengths.
Answer:
Its A
Explanation:
Its A =Have high amplitudes
Low-frequency waves have long wavelengths. Therefore, option B is correct.
What are waves?
Waves are a type of disturbance that travels through a medium or space, transferring energy without transferring matter. Waves can take many forms, including sound waves, light waves, water waves, and electromagnetic waves.
Waves are characterized by a number of properties, including wavelength, frequency, amplitude, and velocity. Wavelength is the distance between two consecutive peaks or troughs in a wave, while frequency is the number of wave cycles that occur per unit of time. Amplitude is the height of the wave, and velocity is the speed at which the wave travels through the medium.
Low-frequency waves have longer wavelengths, which means that they have fewer cycles per second (measured in hertz) and take more time to complete one full cycle. Therefore, option B is correct.

Which of the following explains how fault is formed?
a. Earthquakes shake the rocks to slide horizontally, vertically, or sideward.
b. Gravity pulls on the crust to slide up, down or past each other.
c. Different forces pushing or pulling on the crust causes rocks to slide horizontally, vertically, or sideward.
d. Same force pushing or pulling on the crust causes rocks to slide horizontally, vertically, or sideward.
Answer:
a. Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.
Explanation:
The correct answer is - a.Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.
Reason -
A fault is a fracture or zone of fractures between two blocks of rock.
Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep.
During an earthquake, the rock on one side of the fault suddenly slips with respect to the other.
The fault surface can be horizontal or vertical or some arbitrary angle in between.
Read the paragraph from the section "Pea Plants And The Punnett Square."
A pea plant could have one copy of the height gene that coded for "tall" and one copy of the height gene that coded for
"short." The tall allele is "dominant," and this means that it can mask the other allele. The short allele is called
"recessive." The allele combination of tall-short would result in a tall plant since the tall allele is dominant.
Which option is the BEST definition of the word "mask" as used in the paragraph above?
A pea plant could have one copy of the height gene that coded for “tall” and one copy of the height gene that coded for “short”. The tall allele is “dominant”, and this means that it can mask the other allele.

Where do electrons go after they leave chlorophyll?
Answer:
They leave and find somewhere else to replace the previous electron that had left just like it did and repeats the same process over and over again.
Explanation:
This is what i found on the internet to further explain my response, "The electron lost from the chlorophyll a special pair is replenished by splitting water. The passing of the electron in the first part of the electron transport chain causes protons to be pumped from the stroma to the thylakoid lumen." "When light strikes chlorophyll (or an accessory pigment) within the chloroplast, it energizes electrons within that molecule. ... The excited electrons leave chlorophyll to participate in further reactions, leaving the chlorophyll “at a loss”; eventually they must be replaced."
