Answer:
C I think
Explanation:
Cell A shows active transport and Cell B shows diffusion in the given diagram.
What are the types of transport methods?
All higher organisms, including humans, animals, and plants, go through a process called transportation that is necessary, natural, and part of their physiological makeup. To support life, this interaction is significant as it capabilities by continually shipping, different fundamental materials to and from all pieces of the body including cells, tissues, and organs.Water, hormones, gases, mineral nutrition, organic material, and other things are the primary essential materials. An organism's various modes of transportation include:Active transport Passive transport Facilitated transportDiffusion.The term "active transport" refers to a process in which molecules use external energy to move from a lower concentration area to a higher concentration area against a gradient or obstacle.Any substance's overall movement from a higher concentration area to a lower concentration area is known as diffusion. This can occur between cells or within them. Due to the random movement of their particles, only gases and liquids experience diffusion. It is an essential biological process. It is how things enter and exit cells. It occurs naturally and does not call for any energy.The container or the particles themselves come into contact with one another. In the end, the particles cover the entire container. There is no stirring, shaking, or wafting during diffusion.We refer to this as the concentration gradient down because diffusion is the movement of particles from a higher concentration to a lower concentration.

How can fracking impact water quality? (1 point)
A.Methane leaks make the water supply flammable.
B.Power pumps drain water from rivers and reservoirs.
C.The heated water becomes unfit for consumption.
D.Smelting releases toxic metals into the water supply.
Answers
Answer:
a
Explanation:
Due to the current relationship with groundwater and surface water, fracturing fluids like return fluids might pose a risk to both, hence option a is correct.
What is fracking?It's possible for water to get contaminated during fracking owing to chemicals that are accidentally spilled,in the water during the migration of thermogenic methane gas.
Since a hydraulic fracture might intercept a natural fracture, such as a geological fault, and be connected to the surface, this presents another potential source of pollution.
Therefore, presence in the subsoil may be encouraged during the fracturing process, which may enhance the incidence of chemical reactions and the production of new contaminating substances, hence option a is correct.

(Function) mRNA: carries the information in the DNA to the ribosomes where it is translated into amino acids of proteins, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain during protein synthesis, tRNA: acts as an adaptor molecule, which identifies correct amino acids corresponding to the anticodon present on it

(Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure.
(Function) mRNA: carries the information in the DNA to the ribosomes, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain, tRNA: acts as an adaptor molecule.
What is mRNA, rRNA and tRNA?mRNA carries instructions from the DNA to the ribosome work site. rRNA forms part of the structure of the ribosome and helps to connect pieces together. tRNA brings in the amino acids, which are the pieces that get strung together to make the final protein.
Moreover, the three major types of RNA are: mRNA (messenger RNA) : it provides the template for protein synthesis during translation, tRNA (transfer RNA) : it brings amino acids and reads the genetic code during translation, rRNA (ribosomal RNA) : it plays a structural and catalytic role during translation.
Therefore, the main difference between mRNA and tRNA is that mRNA serves as the messenger between genes and proteins whereas tRNA carries the specified amino acid into the ribosome in order to process the protein synthesis.

The Arizona poppy has adapted to living in areas that receive less rain, but there are still periods of time that a drought occurs. What part(s) of photosynthesis would the plant not be able to perform if there is no rain? What would be the long-term effects on the plant if the drought were to continue? Explain your answer.
Answers
Answer:
I guess it would not grow??
Explanation:
Answer:
When plants lose more water than they can take up from the soil, they become water stressed. ... Such drought conditions certainly inhibit the growth of plants. If it goes long enough without water it will die because the plant uses water for a lot of different jobs needed to keep the plant alive, so the long-term effect is that the plant will die if the drought continues.

A biome is a major community of plants and animals living in a specific geographic area and adapted to specific climate conditions. There are five major types of biomes: grassland, forest, desert, aquatic and tundra.
These major biomes can be divided into different categories (e.g., temperate grasslands).The grassland is a biome that has grasses as the dominant vegetation.The temperate grasslands have in common the same seasonal patterns of temperature and precipitation (Option C).In these regions (temperate grasslands) rainfall is insufficient to support trees.The temperate grasslands have four well-defined seasons. i.e., spring, summer, fall (autumn), and winter.Some examples of temperate grasslands include Argentine pampas, Euro Asian steppes and North American prairies.In conclusion, the temperate grasslands have in common the same seasonal patterns of temperature and precipitation (Option C).

photosynthesis?
Answers
Answer:
six
Explanation:
There are 6 oxygen atoms present in the products of photosynthesis.
What is photosynthesis?Photosynthesis is a process by which green plants, algae, and some bacteria convert carbon dioxide and water into glucose (a sugar) and oxygen, using energy from light. This process takes place in chloroplasts within the cells of plants and is essential for life on Earth, as it produces the oxygen that other organisms breathe and the food that supports the food chain.
The glucose produced by photosynthesis is used by the plant as a source of energy or stored for later use. Additionally, the glucose can be converted into other sugars, starches, and cellulose, which are used to build plant tissues.

Compare the thickness of the right and left ventricles. Which ventricle is thicker the right or left. Explain the difference.
Answers
Answer:
When comparing the thickness of the heart's ventricles, the left one is thicker than the right one, because it must generate more pressure to pump blood throughout the body.
Explanation:
In the human heart, the right ventricle is in charge of pumping the blood to the lungs —initiating the minor circuit of the circulation— while the left ventricle is in charge of pumping the blood to the whole body.
To fulfill its function, each ventricle has a specific thickness in its walls, the left one being thicker than the right one.
The right ventricle is a chamber that handles more volume than pressure, and its walls are thinner because it does not require much pressure to pump the blood to the lungs. The left ventricle has a thicker muscular wall because it is a chamber that must generate a high pumping pressure, so its contraction force must be greater.The structure of the myocardium in the heart is what allows each chamber to fulfill its function adequately.
