Woman P. Boston  vitellaria once had a melanic variant that was caused by a deleterious mutation on chromosome 17. Except for a few melanic variants, the majority of Used are bitularia in Britain were light in color. The first reference of the melanic form was made in Manchester in 1848.

This is a dark peppered moth's first known sighting. Over the following fifty years, what was uncommon in 1848 became the norm. In the vicinity of English cities, peppered moth populations peaked in the year 1900 at around.

I would select the image of the Grand Canyon as evidence that can support an answer to the question of what geologic process could have formed the channel on Mars. The Grand Canyon is a vast canyon carved by the Colorado River over millions of years.

Geologic processes refer to the natural physical and chemical forces that shape and modify the Earth's surface and interior over time.

The channel on Mars is similar to the Grand Canyon in several ways. Both are long, deep, and narrow. Both are carved by water. And both are located in arid regions.

The most likely explanation for the formation of the channel on Mars is that it was carved by water. The water may have come from melting glaciers or from underground aquifers. The water would have flowed downhill, carving the channel as it went.

If mismanaged, renewable resources will become non-renewable.

Explanation:

For example: Groundwater can be over-pumped. If you burn a tree (plant) and don't plant another one.

Yes, a renewable resource can become a non-renewable resource.

A renewable resource is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes.

A non-renewable resource is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption.

Renewable resources can become non-renewable resources if they are used up faster than they can be replenished. Water is a common example of a renewable resource. If the water is used in a huge and big amount by every people of the earth for unnecessary purposes, then day by day the stock of the water level below in the earth will decrease and gradually the water will turn into a non-renewable resource.

Itching and other skin problems are signs that a cat or dog may have flea. Fleas are parasites known for their biting and blood-sucking abilities. When they bite, flea saliva enters the pet’s circulatory system, sometimes causing an allergic response commonly seen as a “hot spot” on the pet’s neck or the base of its tail.

Fleas are tiny parasitic insects that infest the fur of dogs and cats. They feed on blood and cause skin irritation that results in itching. If the problem is severe, it can lead to more significant health issues. Pet owners should watch for signs of fleas and treat their pets promptly to avoid complications. Fleas lay eggs on the skin of dogs and cats, which hatch and develop into larvae.

The larvae feed on the skin, shedding as they mature. Adult fleas emerge from the larvae, biting the host to feed on blood. The process repeats itself, with adult fleas continuing to lay eggs on the skin of the pet.The most common sign of fleas in dogs and cats is itching. Pets will often scratch themselves, bite their skin, or lick excessively to relieve the irritation.

Other signs of fleas include red or inflamed skin, hair loss, and the appearance of small, raised bumps on the skin. These bumps are often referred to as "flea dirt" and are the waste products of the fleas. In severe cases, anemia, an allergic reaction, or the transmission of other parasites or diseases can occur.

Flea infestations can be treated with a variety of products, including topical treatments, shampoos, and collars. It is essential to follow the instructions on the product label and treat the pet and the surrounding environment to eliminate the fleas. Prevention is key to avoiding flea infestations, so pet owners should maintain a regular grooming and flea prevention schedule.

Explanation:

Mitosis in Eukaryotic cells

Figure A = Punctuated equilibrium with rapid changes followed by stability. Figure B = Gradualism with continuous, slow changes.

The best explanation that portrays the distinctions outlined in the chart above is that Figure An addresses interspersed harmony since there is a collection of little hereditary changes over significant stretches of time, trailed by quick change, and afterward change doesn't happen for a while.

Then again, Figure B addresses gradualism since there is a consistent, slow gathering of little hereditary changes over a significant stretch of time.

Accentuated balance is a hypothesis that recommends that transformative changes happen in short eruptions of quick change, trailed by significant stretches of balance or dependability. During these times of strength, next to zero hereditary change happens.

Gradualism, then again, proposes that development occurs at a gradual speed over a significant stretch of time.

In Figure A, we can see that there are times of soundness where there is minimal hereditary change, trailed by an unexpected explosion of quick change.

This example is reliable with the hypothesis of accentuated harmony. In Figure B, there is a constant, continuous change over a significant stretch of time, which is steady with the hypothesis of gradualism.

In synopsis, the primary contrast showed in the graph is the pace of developmental change after some time. Figure An addresses interspersed harmony, while Figure B addresses gradualism.

Option(B) Ureter is the correct option.

The ureter is a vital part of the urinary system in humans. It is a muscular tube that connects the kidneys to the urinary bladder. Each human has two ureters, one attached to each kidney, and they play a crucial role in the transportation of urine from the kidneys to the bladder.

The primary function of the ureter is to carry urine that is produced in the kidneys to the urinary bladder for storage before it is eliminated from the body through urination. The ureters accomplish this by using peristalsis, a wave-like muscular contraction, to propel urine along their length.

The ureters have a complex anatomical course. They originate from the renal pelvis, which is the funnel-shaped structure that collects urine from the kidneys. From there, they extend downward, crossing over the brim of the pelvis and passing behind the peritoneum, the membrane lining the abdominal cavity.

The efficient functioning of the ureters is essential for the proper elimination of waste products and maintenance of fluid balance in the body. Any obstruction or abnormality in the ureters can lead to conditions like kidney stones, urinary tract infections, or urinary reflux.

In summary, the ureters are muscular tubes that transport urine from the kidneys to the urinary bladder. They rely on peristaltic contractions to propel urine, and their structure and positioning help ensure unidirectional flow.
