Answer:

B. Insects with a resistance gene survived the first cyanide sprayings and passed the gene to their offspring

Explanation:

So, just by chance, one or more bugs already had some genes that provided them resistance to fight the cyanide. These bugs survived and the rest died. So since only the resistance bugs survived, they transferred their genes onto their kids and now kids are also immune. Now the cycle continues over generation until everyone is pretty much immune to the sprays.

This is exactly why we are currently facing and will face massive deaths due to bacterial resistance to the antibiotics we use.

The primary component supporting the communications neurons give and receive throughout the body are glial cells. Myelin, a membraneous coating formed by glial cells around axons, acts as an insulator, similar to the insulation around the wires in electrical circuits.

Myelin is a lipid-rich substance that surrounds nerve cell axons, the "wires" of the nervous system, to insulate them and speed up the transmission of electrical impulses (known as action potentials).

The myelinated axon can be compared to an electrical line having insulation surrounding it (the myelin). Myelin does not, however, cover the full length of the axon in a single continuous sheath way the plastic wrapping on an electrical wire does.

Seasons can be determined from a diagram based on the position of the Earth in its orbit around the Sun and the tilt of its axis.

Within the Northern Hemisphere, when the Earth is tipped towards the Sun at a certain angle, summer reigns. Conversely, when the planet is skewed away from its beaming star, winter then follows suit. If neither of these angles is determined, either spring or autumn will arise.

A diagram of the Earth's orbit and tilt can benefit one in visualizing the globe's location in comparison to the Sun's trajectory and extrapolating which season that location is experiencing. Not to mention, additional data regarding the duration of daylight and the direction of the Solar ray's impact may also assist in determining the period.

As an athlete maintains exercise at near-maximum intensity, the substance that will accumulate in the working muscle is hydrogen ions.

During intense exercise, the working muscles rely heavily on anaerobic metabolism to generate energy. This process involves the breakdown of glucose to produce ATP (adenosine triphosphate) without the need for oxygen. However, as glucose is rapidly metabolized, it leads to the accumulation of metabolic byproducts, including hydrogen ions. The accumulation of hydrogen ions in the muscle is associated with a decrease in pH, resulting in a condition known as acidosis.

This acidic environment can have several effects, including impairing muscle function, causing fatigue, and potentially leading to muscle cramps. Creatine phosphate (B) is a high-energy molecule that acts as a rapid source of ATP during short bursts of intense exercise, but it does not accumulate in the muscle. NADH molecules (C) are involved in energy production through cellular respiration but do not accumulate during intense exercise. Glucose molecules (D) are rapidly utilized during exercise and are not expected to accumulate.

Explanation:

The principle behind stacking buckshot pellets is that the greater the angle of surface contact between two pellets, the stronger the tendency those pellets will impart energy in that direction.

Pellets are small, compressed or condensed masses of material, typically made from a variety of substances including wood, metal, plastic, and chemicals. They can be used for a range of applications, such as fuel, ammunition, or as feed for animals.

Surface contact refers to the physical contact between two objects or surfaces that are in close proximity to each other. It is the area where the surfaces touch each other and can have an effect on friction and other physical properties.

According to the given information:

The principle behind stacking buckshot pellets is that the smaller the angle of surface contact between two pellets, the greater the tendency those pellets will impart energy in that direction. This is because when the pellets are stacked closely together, they create a more solid and compact mass which allows for more force to be concentrated in a specific direction upon impact. This technique is often used in shotguns for hunting and self-defense purposes.

Chemotherapeutic agents may selectively act on bacterial cells by inhibiting peptidoglycan synthesis in the bacterial cell wall.

Chemotherapy drugs can destroy bacterial cells by inhibiting peptidoglycan synthesis in the bacterial cell wall. Peptidoglycan is a unique, essential component polymer present in the cell wall of bacteria.

Antibiotics interfere with bacterial cell walls to prevent bacterial growth and proliferation. Human cells do not have cell walls, but many types of bacteria do, and antibiotics can attack bacteria without harming human cells.

Mutation and selection allow bacteria to develop defense mechanisms against antibiotics. For example, some bacteria have evolved biochemical "pumps" that can remove antibiotics before they reach their destination, while others have evolved to produce enzymes that inactivate antibiotics.

Answer:

The cell will shrink

Explanation:

The order of the digestive tract is as follows: oral cavity, pharynx, esophagus, stomach, small intestine, large intestine, and rectum. The function of the digestive tract is to break down food into smaller particles that can be absorbed by the body.

The oral cavity (mouth) is where food is first ingested and mechanically broken down by chewing. The pharynx connects the mouth to the esophagus, which transports the food to the stomach.

The stomach secretes enzymes and acids to further break down the food. The small intestine is where most of the nutrients are absorbed into the body. The large intestine absorbs water and electrolytes, and the rectum stores and eliminates waste.

The salivary glands secrete saliva, which contains enzymes that begin the process of breaking down carbohydrates. The pancreas secretes digestive enzymes into the small intestine to further break down carbohydrates, fats, and proteins.

The liver produces bile, which aids in the digestion of fats. The gallbladder stores and releases bile into the small intestine. These organs work together to ensure the proper digestion and absorption of nutrients.

A contact force must touch an object to influence it. For example you need to push you desk to move it.

A non-contact doesn't need to touch an object to influence it. For example a magnet pulls an object without touching it.

The time for 1 square exists 3 minutes then the time taken for whole office Space to be carpeted

= 3 \(\times\) 54

= 162 minutes.

Therefore, the time required to carpet her 4-yard by 6-yard office space exists 162 minutes.

Given: Office Space is 4 yard by 6 yard

Each carpet square is 2 feet by 2 feet It takes 3 minutes to position each square.

1 yard = 3 foot

The office space exists (4 \times 3) feet by 12 feet by 18 feet.

(6 \(\times\) 3) foot

Area = 12 \(\times\) 18

= 216 \(ft^{2}\)

Each carpet square area = 2 \(\times\) 2 = 4 \(ft^{2}\)

Number of carpet squares to be positioned for whole office space

= 216/4 = 54,

The time for 1 square exists 3 minutes then the time taken for whole office Space to be carpeted = 3 \(\times\) 54 = 162 minutes.

Therefore, the time required to carpet her 4-yard by 6-yard office space exists 162 minutes.
