Compare a sled’s potential energy at 10 m to its potential energy at 20 m. How does doubling height affect potential energy?
Answer:
It has an exponential effect. In contrast, you can reach a point when an object is so heavy that when dropped, it achieves terminal velocity. Without the factors of drag and general friction, all objects will fall at a velocity of around 9.8 meters per second. They must, however, accelerate to that speed. Increasing the high gives the sled more time to reach its top speed. That is, its potential energy grows.

How do geologists study direct evidence of Earth’s interior?
by collecting drill core samples of Earth’s crust
by measuring seismic wave activity
by analyzing how living things survive
by recording changes in climate patterns
Answer: A
Explanation: E2022
Geologists study direct evidence of Earth's interior by measuring seismic wave activity, which is the second option, as the seismic waves are waves of energy that travel through the earth's interior.
What are seismic waves?Geologists use various techniques to study the Earth's interior, but one of the most important is the measurement of seismic wave activity. Seismic waves are generated by various sources, such as earthquakes, volcanic eruptions, and human-made explosions. The waves travel through the earth's interior and can be detected by seismic instruments such as seismometers. Seismic waves come in two main types: body waves and surface waves. Body waves are waves that propagate through the earth's interior, while surface waves travel along the earth's surface. Body waves are further divided into two types: P-waves and S-waves.
Hence, geologists study direct evidence of Earth's interior by measuring seismic wave activity, which is the second option.

If a plant looks purple, which light color is causing the plant to photosynthesize?
Green
O Purple
O Blue
Red
Answer:
Purple
Explanation:
To perform photosynthesis, violet light is the most important color, and it's from these wavelengths that plants get most of their energy. The reason for this is because out of the visible spectrum, red light is the longest wavelength light that the photosynthesis process can use, but it has the least energy
Which of these organisms
has cells that lack a cell
wall?
A. trees
B. fungi
C. plants
D. animals
Animal cells do not have cell walls because they do not need them. Cell walls, which are found in plant cells, maintain cell shape, almost as if each cell has its own exoskeleton. Animals do have a cell membrane though.
What are cell walls?A rigid layer of nonliving material that surrounds the cells of plants and some other organisms. A cell wall is made up of cellulose, pectin, glycoproteins, hemicellulose and lignin. It is the outer boundary of the cell, it encloses the cytoplasm and the organelles of the cells. In plants cells it is inside the cell wall.
Let's take a look at the options:The first one is a tree. A tree is a type of plant and all plants have cell walls and it provides turbidity and durability for the plant. Therefore, a tree has a cell wall eliminating it as a option.The second one is fungi. Fungi are a eukaryotic organism that is usually filamentous (forming a mycelium) and heterotrophic. Fungi have a cell wall made of chitin, a nitrogen containing polysaccharide (NO amino acids) called hyphae. Therefore, fungi have a cell wall eliminating it as a option.The third one is plants. As mentioned before, all plants have cell walls. But to explain more, plant cells are surrounded by a strong cell wall that can change as they grow. It is made of a mixture of polysaccharides cross-linked together, which can give properties like flexibility, strength, turgor and waterproofing. Therefore, plants have a cell wall eliminating it as a option.The last one is animals. Animal cells have a cell membrane instead of rigid walls like plant cells do and that is mainly so they can move. Rigid cell walls don’t move - plants don’t move very much and what movement they do have is very slow and gradual. Animals move constantly - skin has to stretch, muscles must contract and extend. So the cells have to allow for that, and the flexible cell membrane is how they do it. Therefore, the answer is option D.To learn more about cell functions, check out these links:

A hurricane sweeps across a small Caribbean island, killing 50 percent of the herbivore species on the island. What type of limiting factor is this?
A hurricane sweeps across a small Caribbean island, killing 50% of the island's herbivorous species. this is the natural limiting factor.
What is the limiting factor?Limiting factor (or limiting resource) is the designation given to the environmental parameter (biotic or abiotic) that effectively controls the growth of a population in a given biotope or ecosystem, limiting the development of the organism and, therefore, via the size and distribution of the population.
With this information, we can conclude that a hurricane sweeps across a small Caribbean island, killing 50% of the island's herbivorous species. this is the natural limiting factor.

Answer:
Enzyme washing or "bio stoning" is a textile manufacturing technique in which cellulase enzymes are applied to denim. As with traditional stone washing, the intended effect is a faded appearance and softer feel. Because the technique relies on biotechnology, enzyme washing is considered an example of textile bio-processing.
Cellular respiration release CO2 and photosynthesis absorbs CO2. These two reactions are part of which biogeochemical cycle?
A. Carbon cycle
B. Water cycle
C. Phosphorus cycle
D. Nitrogen cycle
Answer:
A
Explanation:
A. Carbon cycle
Cellular respiration is the metabolic reaction that occurs in the cells of organisms. Cellular respiration and photosynthesis both add carbon dioxide to the biogeochemical cycle. Thus, option A is correct.
What is a biogeochemical cycle?The biogeochemical cycle is the process that transfers and moves the abiotic chemical factors through the various spheres of the earth. It includes carbon, water, nitrogen, phosphorus cycle, etc.
The process of cellular respiration releases carbon dioxide as the waste gas into the atmosphere that gets consumed by the plants to make energy that gets eaten by the organism that again releases the carbon dioxide. This cycle of carbon goes on from the producer to the consumer in the ecological chain.
Therefore, cellular respiration and photosynthesis contribute to the carbon cycle.

brainlist pleaseContrast the three types of heat transfer
Answer:
There are three modes of heat transfer.
1. Conduction
2. Convection
3. Radiation
1. Conduction: Heat transfer through the process of conduction occurs in substances which are in direct contact with each other. It generally takes place in solids.
For example: When frying vegetables in a pan. Heat transfer takes place from flame to the pan and then to the vegetables.
2. Convection: In this process, heat is transferred in the liquid and gases from a region of higher temperature to a region of lower temperature. Convection heat transfer occurs partly due to the actual movement of molecules or due to the mass transfer.
For example: Heating of milk in a pan.
3. Radiation : It is the process in which heat is transferred from one body to another body without involving the molecules of the medium. Radiation heat transfer does not depend on the medium.
For example: In a microwave, the substances are heated directly without any heating medium.
