Answer:
This is not true
Explanation:
Wells were used in olden days to store and use water. During those days mechanical pulleys were used to extract water out of wells but now a days modern pumps and lifting equipment are used for bringing underground water to the users.
These days water is supplied through pipes and no traditional bucket or rope is used for pulling out water out of the ground. Though wells exists even today but its usage as a primary source of fresh drinking water is no longer in system but rather they are preferred as water storage units.
Answer:
The use of wells to obtain drinking water is not a modern convenience. It might have been a convenience in the past, but with our technological advancements, the use of wells aren't that popular anymore. It is not disregarded though that the usage of wells aren't dropping to a stop since they are still utilized by people usually living in the rural areas. As for the convenience part, well it isn't as convenient as it seems since establishing the well itself would take so much work.

Cell membrane (plasma membrane) acts as a selective barrier, regulating the traffic of materials into and out of the cell.
The cell membrane, also known as the plasma membrane, is a crucial component of all living cells. It serves as a selective barrier that controls the movement of substances into and out of the cell. This selective permeability is essential for maintaining the cell's internal environment and regulating the exchange of nutrients, gases, and waste products. The cell membrane consists of a lipid bilayer embedded with proteins, and its hydrophobic interior prevents the passage of most polar molecules.
To facilitate the transport of specific substances, the cell membrane contains various proteins, including transport proteins, receptor proteins, and enzymes. These proteins help regulate the flow of ions, nutrients, and signaling molecules across the membrane. Overall, the cell membrane is a vital structure that ensures the cell's survival and functionality by controlling its interactions with the external environment.

The cell membrane acts as a selective barrier, regulating the traffic of materials into and out of the cell.
The structure that acts as a selective barrier, regulating the traffic of materials into and out of the cell is the cell membrane or plasma membrane.
The cell membrane is composed of a phospholipid bilayer with embedded proteins that control the movement of substances in and out of the cell. It selectively allows certain molecules to pass through while keeping others out, maintaining homeostasis within the cell.
For example, the cell membrane regulates the entry of nutrients and gases into the cell, as well as the removal of waste products and excess substances. It ensures that the cell maintains the appropriate balance of substances for proper functioning.

Stabilizing selection and disruptive selection are both examples of natural selection that affect population variation. In stabilizing selection, the average phenotype is favored, selecting against extreme variation. Disruptive selection, on the other hand, selects for extreme phenotypes, while the average phenotype is selected against.
Stabilizing selection and disruptive selection are both examples of natural selection that affect population variation.
In stabilizing selection, the average phenotype is favored, selecting against extreme variation. For example, in a population of mice that live in the woods, natural selection favors individuals that blend in with the forest floor and have a brown coat, while lighter or darker mice stand out and are more likely to be preyed upon.
Disruptive selection, on the other hand, selects for extreme phenotypes, while the average phenotype is selected against. For instance, if a population of birds lives in an environment with two distinct food sources, those with short beaks may be better adapted to feed on small, soft fruits, while those with long beaks may be more efficient at capturing insects. Birds with medium-sized beaks may struggle to effectively exploit either food source.

Alpha wavesA healthy adult at rest is most likely to show an EEG pattern characterized by a high level of alpha waves.
Alpha waves are types of brain waves detected by using medical equipment such as magnetoencephalography (MEG) or electroencephalography (EEG), which measures the oscillation of electrical impulses in various sections on the scalp. Alpha waves usually come from the occipital lobe when the eyes are closed during wakeful relaxation such as when performing aerobic exercise. Alpha waves are minimized when sleeping or when the eyes are opened.
