Turgor pressure is the pressure exerted on a plant cell wall by water. When wilted plants are placed in water, they demonstrate increased turgor pressure and become straighter. What is occurring at the cellular level when plants display increased turgor pressure?
Answers
Answer: When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.
Explanation:
Turgor is a phenomenon in plant cells in which the cell expands due to the pressure exerted by the fluids and also by the cell content on the walls. It is related to osmosis, since the external pressure is usually very high and this internal pressure dilates the cell as much as the elasticity of the membranes allows. Then, the cells swell by absorbing water, tensing the membranes because of the pressure against them. When the fluid exerts outward pressure on the cell wall it is called turgor pressure. Whereas, the inward pressure exerted on the cell contents by the stretched cell wall is called wall pressure. Generally, both pressures, turgor pressure and wall pressure, are counterbalanced and balanced.
So, this pressure of turgor facilitates the elongation of the cells in the plant, and also, the cells use this phenomenon to regulate the transpiration through the opening and closing of the stomach.
Thereby, the turgor of a living cell is influenced by three primary factors:
An adequate supply of water.The formation of osmotically substances.A semi-permeable membrane.Vacuoles are organelles bounded by a single membrane and present in plant and fungal cells, and where water is stored. Plant cells control their turgor pressure through the movement of water into or out of vacuoles. When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.
Answer:
When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.'

In general, what types of substances tend to be acidic
Answers
Answer:
- Any pH on the pH scale that tends to be less than a 7 is an acidic substance. (Examples like:Lemon juice and vinegar)
The types of substance that is tends to be acidic are substance with PH lower than 7.
An acid can be regarded as molecule that can donate protons, this us referred as Brønsted–Lowry acid, or that can produce a covalent bond with an electron pair i.e Lewis acid. One of the properties of acid is that it turn blue litmus paper to red, and has a sour taste.To determine an acid, pH scale is helpful.pH scale can be regarded as one used to to determine the acidity or basicity of an aqueous solution. Acidic solutions are one with pH of (0-6), while alkaline has pH of (8-14) on this scale.Examples of acids substance are;
inorganic substances such as sulfuric and nitric, hydrochloric, organic compounds such as carboxylic acid, sulfonic acidTherefore, substance with lower pH are regarded to be acidic.

Answers
Answer:
Homologous
Explanation:
Homologous structures are similar organs or structures that are found in different animals that suggest they come from a common ancestor. This is evidence of evolution.
The structures might not necessarily look identical and might not perform the same function. For example, the flippers of a dolphin, the wings of a bird, the legs of a dog, and the arms of a human are considered homologous structures.

Which of the following is(are) non-technological ways of improving air quality?
a. using public transportation
b. building wind turbines
c. turning lights off when leaving a room
d. both a and c
Answers
Using public transportation and turning lights off when leaving a room are both non-technological ways of improving air quality. Therefore, (A) and (C) are correct.
What is air quality?An air quality index is a tool that is used by government agencies to communicate with the general public about the current level of air pollution as well as the level of air pollution that is expected to occur in the near future.
The Clean Air Act regulates a number of key air pollutants, including ground-level ozone, particle pollution, carbon monoxide, and sulfur dioxide. The AQI is determined based on these four pollutants. The Environmental Protection Agency (EPA) has developed national air quality standards to safeguard the general population from each of these contaminants.
We can improve the quality of the air by:
Try to cut down on the amount of times you drive your vehicle.Use of fireplaces and wood stoves should be cut back or eliminated entirely.Avoid burning anything, including leaves, rubbish, or other objects, on fire.Try to avoid using lawn and garden equipment that is powered by gas.Learn more about AQI, here;

What type of organism is an Autotroph?
Answers
Answer:
Explanation:
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.
Because of high increases in populations, some underdeveloped countries are already exceeding their carrying capacity. They cannot produce enough food to support their populations. These regions are undergoing very rapid desert formation. Growing populations contribute to this by clearing forests for agriculture and firewood. Which region in the table is most likely experiencing desert formation? Explain.
Hint: Think about where the population is increasing the most quickly.

What is true about Structure A
please answer if not then that’s fineee
Answers
Answer:
✔️Facilitated diffusion does not require any of cell energy.
Explanation:
The above structure A is known as Cell Membrane. It is a permeable membrane through which materials are diffused or transported in and out of the cell.
Option A is true for structure A because facilitated diffusion does not require the cell's energy. Facilitated diffusion is passive transport of molecules or ions across the membrane which is spontaneous.
It is passive because facilitated diffusion does not directly require chemical energy from ATP hydrolysis. What happen is that molecules and ions move down their concentration gradient. This movement reflects their diffusive nature.
