Think of the shape of a wave. It looks like a squiggly line. We know the highest part of that line is the peak. The wavelength is the distance between wave peaks. Waves of the same type can differ in wavelength. For example, the wavelength of light waves determines its color. Amplitude is the measurement of a wave's height. It is measured in two ways. Peak-to-peak amplitude is the distance between the peak (the topmost part of a wave) and the trough (the lowermost part). Semi-amplitude is half the peak-to-peak amplitude. Most of the time when people refer to "amplitude," they are referring to the semi-amplitude: the distance from the middle of the wave to the top, or the middle of the wave to the bottom. The amplitude of a sound wave determines its volume.
Which of the following best explains the relationship between peak-to-peak amplitude and semi-amplitude?
A Semi-amplitude is half the distance of the peak-to-peak amplitude.
B Semi-amplitude is the same distance as the peak-to-peak amplitude.
C Semi-amplitude is double the distance of the peak-to-peak amplitude.
D Semi-amplitude is always greater than the peak-to-peak amplitude.

List 3 negative impacts does plastic pollution have on the ocean?
Answers
Ingestion
And suffocation
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.

Answers
it’s melting
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.

Binomial nomenclature is a system of naming a species using two names, the genus and the species (and sometimes subspecies), which make up the scientific name of a species. Examples include Panthera tigris for the tiger, and Canis lupus for the gray wolf.
Phylogeny, or phylogenetics, is the study of the evolutionary development of organisms and relationships between them. Phylogeny is a useful tool for taxonomists.

This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answers
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.

B-the size of the plants’ leaves
C-the volume of water the plants receive
D-the amount of light the plants receive
THANKKS

Answer:
A
Explanation:
I'm pretty sure it's A because:
A- The kind of pots doesn't affect the growth of the plant
B- The size of the leaf changes according to the sunlight
C- The volume of water the plants receive is a variable that if changed can change a lot of the plants to a point where it can kill them.
D- The amount of light a plant receives is crucial to the plant, it is not an independent variable
They are controlling/changing where the plant is going, independent variables are what is being changed or controlled. Everything else is identical or the same making the amount of sunlight the answer.

Explanation:
Answer:
plants or animals that migrated to new places where they are not native
Explanation:
Invasive species are non-native species that cause harm to the environment, economy, or human health. These species often outcompete native species for resources, prey on native species, and disrupt the natural balance of the ecosystem. They can also spread diseases to other species, and cause significant economic damage. Examples of invasive species include the emerald ash borer, zebra mussels, gypsy moths, and Asian long-horned beetle.
