Answer:
wind erosion
- i know this question is older but i hope this helps anyone who may need it. :-)
The geologic process that creates an alcove is wind erosion, which is present in Option B, as the alcove is a recessed area in a rock or cliff face that is often semicircular in shape.
What is wind erosion?Alcove is created by the process of wind erosion. Over time, wind can carry abrasive particles, such as sand or small rocks, that erode the softer rock on the face of a cliff, carving out a hollow space. As the wind continues to erode the rock, the hollow can deepen and expand, forming an alcove. Alcoves are often found in areas with strong, consistent winds, such as desert regions, and can range in size from small niches to large, room-sized spaces. In addition to wind erosion, alcoves can also be created by other geologic processes such as water erosion or tectonic activity.
Hence, the geologic process that creates an alcove is wind erosion, which is present in Option B.

What particle in an atom determines what element it is?
Answer:
Protons
Explanation:
The number of protons in the nucleus determines which element an atom is, while the number of electrons surrounding the nucleus determines which kind of reactions the atom will undergo. The three types of subatomic particles are illustrated below for an atom of helium—which, by definition, contains two protons.

Which best describes pitch?
the amount of time taken for a longitudinal wave to produce one cycle the number of cycles per second perceived by the human ear the amplitude of a wave when the natural frequency is matched the distance between two corresponding parts of a transverse wave
The answer is B. the number of cycles per second perceived by the human ear
I got this question right :)
The pitch is the number of cycles per second perceived by the human ear. The correct option is B.
What is pitch?The ability to assess sounds as "higher" and "lower" in the sense associated with musical melodies is known as pitch.
Pitch is a perceptual feature of sounds that allows their ordering on a frequency-related scale.
Pitch in physics refers to a sound wave's specific frequency, which is expressed in Hertz (Hz).
There are two ways in which these frequencies match musical notes. high tone: A high pitch is one that vibrates at a high frequency.
Pitch is a perceptual quantity that depends on the listener, but frequency is a physical quantity that indicates the number of vibrations per second. In truth, our ears perceive pitch rather than frequency.
The pitch is how many cycles per second the human ear can detect.
Thus, the correct option is B.

Glucose is what type of molecule A: Multi- complex B: Protein C: Sugar D: Lipid
Answer:
Within all lifeforms on Earth, from the tiniest bacterium to the giant sperm whale, there are four major classes of organic macromolecules that are always found and are essential to life. These are the carbohydrates, lipids (or fats), proteins, and nucleic acids. All of the major macromolecule classes are similar, in that, they are large polymers that are assembled from small repeating monomer subunits. In Chapter 6, you were introduced to the polymers of life and their building block structures, as shown below in Figure 11.1. Recall that the monomer units for building the nucleic acids, DNA and RNA, are the nucleotide bases, whereas the monomers for proteins are amino acids, for carbohydrates are sugar residues, and for lipids are fatty acids or acetyl groups.
Explanation:
Three that live in the savanna are lions, giraffes, and elephants. Choose two of these animals. For each one, describe an adaptation that has enabled it to survive in the savanna. Then tell which which animals in the population would be more likely to survive if a dry season was unusually long.
Giraffes and Elephants: Giraffes have adapted a long neck over time letting them eat and access food allowing them to survive. If a dry season was unusually long they would succeed fine because they are able to eat and drink from the trees. Elephants have survived with similar tactics of eating higher up, they have rough skin allowing them to outlast the heat, and only need water after long periods of time.

Are eukaryotes more closely related to bacteria or to archaea? Explain.
Hello!
The Answer Is: Bacteria and Archaea are comprised exclusively of microorganisms; plants, mammals, and microorganisms such as fungi and protists are contained in the Eukarya. Because of their lack of a nucleus, the Bacteria and Archaea were grouped together and called Prokaryotes, but the Archaea are more closely connected to the Eukaryotes than to the Bacteria. The cell walls of bacteria contain a compound called peptidoglycan, while the cell walls of archaea do not. Archaea and bacteria also vary because the composition of the cell membranes of archaea is peculiar and does not contain the same lipids, or fats, present in other species' cell membranes.Thank you for asking this question!

Which statement best describes the purpose of Earth's spheres?
They work together as open systems to cycle matter through ecosystems.
They work independently as closed systems to cycle matter through ecosystems.
They work together as open systems to move matter to living and nonliving parts of Earth.
They work independently as closed systems to move nutrients to living and nonliving parts of Earth.
Answer:
and they work together to drive the processes of the planet.
Explanation:
Earth has four 'spheres,' called the geosphere, hydrosphere, biosphere and atmosphere. These spheres each have unique properties and features, but they are not isolated on Earth, and they work together to drive the processes of the planet.
They work together as open systems to cycle matter through ecosystems. This statement best describes the purpose of Earth's spheres.
What are earths spheres?Lithosphere encompasses the entire solid land of the planet's crust, as well as the semi-solid land beneath it and even the molten core.Hydrosphere is made up of all of the planet's water, which comes in solid, liquid, and gaseous forms. Water comes down to the Earth's surface as precipitation from the atmosphere, rivers and streams along the surface, and groundwater beneath the surface. The majority of the world's freshwater, on the other hand, is frozen.Biosphere is made up of all the living things on the earth. This sphere contains all of the Earth's bacteria, plants, and animals. Living beings establish ecological communities in the biosphere based on their physical surroundings. Biomes are the names given to these types of communities.Deserts, grasslands, and tropical rainforests are just a few of the biomes found inside the biosphere.Atmosphere is made up of all of the air in the Earth's system.The biosphere's organisms are shielded from the sun's UV radiation by the upper atmosphere. It absorbs and emits heat as well. Weather occurs in this sphere as well.
These spheres interact via affecting one another, as well as through biogeochemical cycles and other natural phenomena that each of these spheres influences and causes.

The Hershey-Chase Experiments is a well known experiment done by scientist, Alfred Hershey and Martha Chase. They conducted the experiment in the year 1952.
It was an extra ordinary experiment which made the world believe that the DNA is the genetic material and not a protein. In their experiment, they tried to find out if the protein coat or the core of the DNA of the virus which enters into the infected cells would help them to understand whether the genes were made of DNA or of protein.

Answer: Diagnosing cystic fibrosis is a multistep process, and should include a newborn screening, a sweat test, a genetic or carrier test, and a clinical evaluation at a CF Foundation-accredited care center. Although most people are diagnosed with CF by the age of 2, some are diagnosed as adults. Also cystic fibrosis carriers do not have CF and are generally asymptomatic, there is emerging research which is finding that some carriers may have very mild symptoms associated with the genetic mutation. These symptoms may be a very pale shadow of the more severe symptoms someone with CF has.

Answer:
Amylose is a straight chain whereas amylopectin is a branched chain polymer.
Explanation:
Amylose differs from amylopectin because amylose is a straight chain while on the other hand, amylopectin is a branched chain polymer. Branched chain polymers refers to main chain with smaller chains as branches of main chain while straight chain polymer has only main chain and no branches of main chain. Starch comprise of about 10-20% amylose and 80-90% amylopectin. Starch is considered as the main storage of energy for green plants.
