Explanation:
In which location would be rate of soil erosion most likely be higher than the rate of soil formation? A. A river delta B. A steep slope C. A tropical area with moderate rainfall d. A temperature forest
Answer:
B. A steep slope
Explanation:
The rate of erosion is the highest on barren lands and on steep slopes. The steep slopes are much more easy to erode because the gravity is pulling downwards, and the angle of the slope is helping that a lot. Also, the steeper the slope is, the less vegetation there is, thus the soil usually is not protected from erosion. When there's rain, snow, stronger winds, they manage to pull down the soil with ease as there's nothing that is an obstacle to stop them. That results in gradual leveling up of the slope, constantly losing on height, and eventually being totally flattened.
Final answer:
The rate of soil erosion is likely to be higher than the rate of soil formation on a steep slope due to more runoff and less vegetation to hold the soil in place.
Explanation:
The location where the rate of soil erosion would most likely be higher than the rate of soil formation is B. A steep slope. This is because soil can only develop where surface materials remain in place and are not frequently moved away by processes such as mass wasting. Steep slopes usually have more soil erosion due to several factors: more runoff of rainwater, less water infiltration, and less vegetation to anchor the soil. This results in little or no soil as the formation cannot keep up with the erosion. Other locations like river deltas, tropical areas with moderate rainfall, and temperate forests have mechanisms that help in soil accumulation or experience a balance between soil formation and erosion.

how do levels of thermal energy and speed differ between low and high friction surfaces? how does this difference relate to a transformation of energy?
- "This energy is usually in the form of low-level thermal energy. It is only possible to extract work when there is a temperature difference, so low-level thermal velocity; this means that the force of friction and the applied force are equal in magnitude."
- "An energy transformation is the change of energy from one form to another. Energy transformations occur everywhere every second of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical."
Answer:
Speed reduces with increased friction while thermal energy increases with increased friction
Explanation:
The higher the friction between two surfaces the higher will be the thermal energy while the lower will be the speed.
While in case of no or low friction between two surfaces, the thermal energy will reduce while the speed increases tremendously and causes slipping.
The energy transforms from kinetic energy to frictional energy and then to thermal energy.

Final answer:
Carbon is the most versatile element in living organisms due to its ability to form stable covalent bonds with various elements, creating complex organic molecules vital for life.
Explanation:
The element considered the most versatile in living organisms is carbon, primarily because of its unique chemical bonding properties. Carbon's four outer shell electrons allow it to form four covalent bonds with a variety of other atoms, leading to a vast diversity of complex organic molecules essential for life. This capability enables the formation of the four major types of biological molecules: carbohydrates, lipids, proteins, and nucleic acids, all of which play crucial roles in the structure and function of living cells.

What are the products of cellular respiration in a living tissue culture when maintaining in a glucose solution with adequate oxygen
Answer:
The answer is
aerobic respiration and the products of that are Carbon Dioxide and Water.
Glucose and oxygen react to form ATP. Water and carbon dioxide are released in the form of byproducts.
What is cellular respiration?Cellular respiration is a sequence of chemical processes that break down glucose to generate Power, which can then be used as energy to power a variety of reactions all through the body.
Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Cellular respiration is the process by which organisms (animals and plants) decompose sugar in the presence of oxygen in order to release energy in the form of ATP. As a byproduct of this process, carbon dioxide and water are produced.
Thus, during culture of living tissues, with glucose and adequate oxygen, the products of cellular respiration will be water and carbon dioxide.

What domain and kingdom do all invertebrate animals belong to
Answer:
Domain: eukaryotic
Kingdom: Animal
Explanation:
The Animalia kingdom constitutes the group of eukaryotic, heterotrophic, multicellular and tissue organisms, characterized by their capacity for locomotion, their embryonic development and the absence of chlorophyll. Animalia is a kingdom comprised in the Eukaryota domain.
Taxonomically, eukaryotic, is the domain (or empire) to which the organisms formed by cells with a true nucleus belong.
Invertebrate animals belong to the Eukarya domain and the Animalia kingdom. They account for about 95 percent of Animalia species. The largest phylum within this group is Arthropoda, which makes up about 85 percent of all known species.
Explanation:All invertebrate animals belong to the domain Eukarya and the kingdom Animalia. Invertebrates, which include animals without a backbone, make up approximately 95 percent of all species in this kingdom. This group encompasses a diverse range of species from 32 different phyla, perhaps most notably the phylum Arthropoda, which comprises around 85 percent of all known species and is dominated by invertebrates like insects, spiders, and crustaceans.
The domain Eukarya is characterized by organisms that have cells with a nucleus and other membrane-bound organelles. The kingdom Animalia, within this domain, includes all eukaryotic, multicellular, heterotrophic organisms that ingest their food and often develop into motile creatures with a fixed body plan. Among the distinctive features of members of the animal kingdom are the presence of differentiated tissues such as nerve, muscle, and connective tissues.

The rock in the picture is rhyolite, an extrusive igneous rock. Based on its appearance, how would you classify this rock?
please and thanks!
Answer:
A. Felsic
Explanation:
The rock would be classified as a FELSIC rock based on its appearance.
To classify a rock based on its appearance, we would rely more on the features we can observe when we look at it. Some of the features are colour and mineral grains. We can also use its feel, cleavage, and some other physical properties.
Looking at the picture, the rock is light coloured. The mineral grains also have a fine texture because the mineral boundaries cannot easily be resolved by naked eyes.
A light coloured igneous rock is said to be FELSIC with a rich composition of silica and feldspars. Mafic igneous rocks are usually dark and have low silica contents.
From the texture of the mineral grains, we know the rock is an extrusive rock. It must have formed on the surface or very close to the surface. This implies that, the minerals could not grow into larger crystals. They cooled rapidly on encountering surface temperatures.
A rock of this type is a Rhyolite. The intrusive equivalent is granite. Granite differs from Rhyolite because they have large mineral crystals. They are both felsic.

why is chlorophyll not able to capture the energy in green light
All plants have chlorophyll-a which blocks(reflects) green light and absorbs red and blue wavelengths. It seems like it would be more efficient for plants to absorb green light since energy is most powerful from the sun through green wavelengths. However, the chlorophyll-a in chloroplasts actually defend the plant from harmful damage of the TREMENDOUS amount of power from the sun transmitted in green wavelengths.
SO CHLOROPHYLL-A PROTECTS PLANTS FROM TOO MUCH ENERGY IN GREEN LIGHT.

Hope I helped!
Brainliest?
Final answer:
Lichens are used as indicators of air quality due to their sensitivity to pollutants, with their health and abundance being used to monitor environmental conditions. Their decline signals increased air pollution, while their presence indicates cleaner air. They also have ecological and historical significance.
Explanation:
Lichens are excellent biological indicators of air quality due to their extreme sensitivity to pollutants, particularly nitrogenous and sulfurous compounds. These organisms lack roots, thus they absorb water and nutrients over their entire surface area, making them especially vulnerable to pollutants dissolved in rainwater. The U.S. Forest Service and National Park Service utilize the health and abundance of lichen populations in an area to monitor air quality. When lichens decline or disappear from an area, it is often a sign that the air is heavily polluted. Conversely, their presence usually indicates cleaner air conditions.
A purebred talk pea plant is crossed with a purebred short pea plant. All of the resulting offspring are tall. What does this tell you about the gene controlling pea plant height?A. The short version of the gene wasn’t passed from the short parent to the offspring. B. The short version of the gene is dominant to the tall version of the gene. C. The tall version of the gene is dominant to the short version of the gene. D. The tall version of the gene wasn’t passed from the tall parent to the offspring.
Answer and Explanation:
We assume that the tall version has genes denoted by T, and short versions have genes denoted by t.
Purebred tall version will have genotype TT, and short version, tt.
The Punnett square for the crossing between purebreds would be the following:
T T
t Tt Tt
t Tt Tt
Which means that the offsprings all have genotype Tt. If they appear tall, this implies that the tall variety (T) is dominant, so the phenotype of the short version is not expressed.
Conclusion: The tall version of the gene is dominant to the short version of the gene.
The tall pea plant gene is dominant, and the short pea plant height is submissive. Each offspring has both genes, but since the tall gene is dominant, it is the only gene that shows up. Thus, option "C" is correct.
How, explain your answer?From a heterozygous cross (Tt x Tt) the produced offspring would consist of:
25% TT -it would be tall-.
50% Tt -it would be tall as the gene T is dominant-.
25% tt -it would not be tall-.
Thus the produced offspring that would be tall is (50% + 25%) 75%. The answer is option C.
