Mycorrhizae is an adaptation that enhances the uptake of water and minerals by roots.

Mycorrhizae are the associations that exist between fungi and roots.

In around 90% of all terrestrial plants, these symbiotic relationships can be discovered.

A root-like structure and a network of mycelium that spreads into the soil outside of the tree roots make up the mycorrhizal fungi.

By taking in nutrients, this mycelium then transfers those nutrients back towards the host plant.

The absorption surface area of the root system grows as a result. The plant can get more moisture and nutrients because its mycorrhizae, or roots, are significantly larger. This is crucial for phosphorus uptake, which is one of the main nutrients that plants need.

The International Whaling has proposed a negative kill limit for bluefin tuna as well as a countrywide ban on commercial whaling.

Why do humans value blue whales?

Although blue whales have a huge food requirement, the ocean environment benefits from them rather than is burdened by them. Their iron-rich excrement is a crucial supply of nutrients for the marine food web, boosting production in the Southern Ocean and increasing fisheries yields.

How do whales protect the environment?

The "whale pump"—the way whales graze, poop, migratory, then dive between the ocean's top and depths—moves vital nutrients around the ocean. Thus, robust water bodies and the development of cyanobacteria are supported, which in turn helps lock in a significant quantity of carbon.

The adaptation that helps the both organisms to survive is the proboscis.

The hummingbird also has a long proboscis, which it uses to feed on nectar from flowers. It also has the ability to hover in place, which allows it to feed on nectar from flowers that are difficult to access. Additionally, hummingbirds have a high metabolism that allows them to maintain a steady body temperature, and their wings are adapted for fast and agile flight.

Both the Sphynx moth and hummingbird have adaptations that allow them to efficiently feed on nectar, which is their primary source of food. Both species have a long proboscis that allows them to reach deep into flowers and extract nectar. They also have adaptations that allow them to fly quickly and maneuver easily, which helps them to locate and feed on nectar-rich flowers.

Explanation:

Hypertonic cells contain more water than their surroundings. A cell is hypotonic if it contains less water than its surroundings. If the cell has the same amount of water, it will be isotonic.

If the cell has more water than its surroundings, it is hypertonic (think of hyper as having a lot of sugar). The cell will desire to release water. The cell may shrivel or shrink as a result of this. If a cell has less water than its surroundings, it is hypotonic (think hippos). They enjoy eating. The cell will absorb water, which may cause it to enlarge, swell, or even explode. If the cell has the same amount of water/proportion of water to other components, nothing will happen and the cell will be isotonic. (Think solitary, without any interactions with other objects.)

Hypertonic cells have a higher water content than their surroundings. If a cell has less water than its surrounds, it is hypotonic. Isotonic means that the cell has the same quantity of water.

Explanation:

Hope this helps!

The correct answer is c. The rate of photosynthesis decreases drastically.

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose or other sugars. Chlorophyll, the pigment responsible for absorbing light during photosynthesis, absorbs light most efficiently in the blue and red regions of the spectrum, with a peak absorption in the red.

While red light is absorbed by chlorophyll, it is not the most efficient wavelength for photosynthesis. Therefore, if a plant were to be exposed to only red light, the rate of photosynthesis would decrease drastically compared to if the plant were exposed to a full spectrum of light, including blue light.

A disinfectant used to clean surfaces, hands, and skin is potassium hydroxide. Lye, commonly known as potassium hydroxide, is an inorganic substance with the chemical formula KOH. It is sold in a variety of forms, including pellets, flakes, and powders. Potassium hydroxide, sometimes known as caustic potash, is an inorganic chemical with the formula KOH. KOH is a typical strong basic, along with sodium hydroxide. It has numerous industrial and specialised uses, the majority of which make use of its caustic properties and acid reactivity.

KOH is a typical food ingredient that is utilised in the production of cocoa, chocolate, and soft beverages. It has several qualities, including thickening and stabilising effects in dishes like ice cream. Additionally, KOH makes baked foods like pretzels crispier. It can be used as a preservative in food. Potassium hydroxide is a stabiliser, thickening agent, and pH adjuster in food. Based on the observance of various good manufacturing practise conditions of use, the FDA has determined that this ingredient is generally safe as a direct human food ingredient.

pOH is the negative logarithm of the compound OH; therefore, pOH is -log1, which equals 0. In light of typical settings of 25 degrees Celsius, pH is therefore 14-pOH, or 14. So that is as simple as a solution at 25 degrees can be.

Biomagnification refers to the process by which toxins or other harmful substances become more concentrated as they move up the food chain. It occurs when a substance enters an ecosystem and is taken up by small organisms, which are then consumed by larger organisms. Each time an organism is consumed, the substance is concentrated in the body of the larger organism, leading to higher and higher levels of the substance in the organisms at the top of the food chain.

For example, imagine a fictional substance called "X" is released into a lake. The "X" is taken up by small aquatic plants, which are then consumed by small fish. The small fish are then consumed by larger fish, and so on, up the food chain. By the time the substance reaches the top predator in the ecosystem, such as an eagle, the concentration of "X" is much higher than it was in the small aquatic plants at the bottom of the food chain.

The sentence "We learned that the solution to pollution is not dilution" relates to biomagnification because it highlights the idea that simply diluting a pollutant by spreading it out over a larger area does not necessarily make it less harmful. Instead, it may just lead to the pollutant being taken up by more organisms, leading to higher levels of the pollutant in the food chain, and potentially more harm to the ecosystem and the organisms living in it.

The toxin could bind to any of the sites other than the catalytic site that are important for RNA polymerase to work in transcription. Examples of these are DNA entry and exit channels, the RNA exit chanel, the nucleotide entry channel, and the protrusions show within the polymerase that separate DNA strands and guide the exit of the RNA.

All living things, including many viruses, include RNA polymerase, often known as DNA-directed RNA polymerase or RNAP. These RNAPs, which are found in bacteria, archaea, and even eukaryotes, all have identical protein core structures and workings.

In molecular biology, an enzyme called RNA Polymerase, often known as RNA Pol or RNAP, synthesises RNA from a DNA template. With the aid of the enzyme helicase, which breaks down damaged DNA strands, RNA polymerase copies the DNA sequence into an RNA sequence during the transcription process.
