A concave lens is called a diverging lens In concave lens, spherical surfaces are recessed inwards.

It is thinned out in the middle.

When parallel beam of light is passed through concave lens, light rays spread out to different directions.

Hence, a concave lens is called a diverging lens.

Nearsightedness (myopia) is corrected with lenses called “minus power lenses.” They are concave-shaped and help the eyes focus light properly. Myopia causes a person to see distant objects as blurry. Prescription eyeglasses or contact lenses can usually correct this blurry distant vision.

The focusing power of an eye with myopia is stronger than a normal eye. It brings light to a focal point in front of the retina, instead of on the retina.

A lens used to correct myopia works by reducing the focusing power of the eye. This is why it is called a "minus power lens" (or "minus lens").

Minus lenses are concave in shape. In other words, they are thinnest at the center and thicker at the edge. This lens shape moves the focus of light from in front of the retina directly onto its surface. This shift corrects the blurry distance vision caused by nearsightedness.

The power of a lens that corrects myopia is measured in units called diopters (D). The lens powers on an eyeglass prescription for myopia always begin with a minus sign. The higher the power number of the lens, the more myopia it corrects.

For example, a -6.00 D lens corrects twice the amount of nearsightedness as a -3.00 D lens.

High-index lenses are typically recommended for correcting nearsightedness greater than -3.00 diopters. They are thinner and lighter than regular plastic lenses, so they are more attractive and comfortable.

Its actually concave lenses

Explanation:

As someone who wears glasses, there are different lenses or 'levels' of eyesight that requires a personalized prescription.

Answer:

S - Savannas are typically found in tropical or subtropical regions.

S - Savannas tend to have more trees and shrubs.

S - Savanna's climate is drier than that of a grassland.

G - Grasslands are found in temperature regions.

G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.

G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.

B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.

B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.

B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

Answer:

Horseshoe crabs are chelicerates, which means they're made of two segments, the cephalothorax and the abdomen. The cephalothorax is a fusion of the head (cephalon) and chest (thorax), and the tail is part of the abdomen. Trilobites, on the other hand, are composed of 3 parts, cephalon, thorax, and pygidium. In this body plan, the pygidium is the tail and is a separate segment of the body. Due to these differences, it seems that the two species are not closely related, however, it's quite possible that they share a yet-undiscovered common ancestor.

Answer:

D

Explanation:

the ozone layer formed and began to shield the surface of the Earth from the harmful ultraviolet light. This allowed life forms to evolve to survive on the surface of the oceans and on land and also allowed organisms who metabolize oxygen (like us!) to develop.

The change in the Earth's atmosphere which allowed life to form is the development of an ozone layer. Thus, the correct option is D.

The ozone layer is a region of the Earth's stratosphere which absorbs most of the Sun's ultraviolet radiations. Earth's stratosphere contains a high concentration of ozone in relation to other parts of the atmosphere, although it is still present in small amount in relation to other gases in the stratosphere.

The ozone layer in the stratosphere absorbs a big portion of the radiations from the sun, preventing it from reaching the planet's surface. Most importantly, ozone absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light which comes from the sun that has several harmful effects.

Therefore, the correct option is D.

Answer:

Negative physical impact on marine life, chemical impact on the water, and transport of native species.

Explanation:

Negative physical impact on marine life:

Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.

Chemical impact on the water:

Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.

Transport of native species:

Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.

Explanation:

It should take about 6 weeks to see the Germination, until then continue watering it and giving it sunlight

The seed germination investigation during the students' summer vacation involves selecting various seeds (e.g., beans, peas, sunflower) and setting up an experiment. They will place the seeds in different conditions, like light vs. dark or wet vs. dry, and pot the same seed in multiple pots. Throughout the investigation, the students are expected to carefully observe and document the changes that take place over time, including the growth of roots and shoots. This hands-on approach allows them to gain practical knowledge of seed germination and develop essential scientific skills in observation, data collection, and documentation.

From the diagram of the rock cycle the missing part is ( B ) ; Melting

Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.

Magma is released to the earth surfaces during volcanoes therefore the missing term  in the rock cycle is melting

Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.
