Answer:
es la C. Electromagnetic waves travel at different speeds.
The correct option is B i.e. Electromagnetic waves can travel long distances.
what are electromagnetic waves?Electromagnetic waves, or EM waves, are waves that are formed when an electric field and a magnetic field vibrate together. EM waves, in other words, are made up of oscillating magnetic and electric fields. When an electric field collides with a magnetic field, electromagnetic waves are created. As a result, they're called 'electromagnetic' waves.
An electromagnetic wave's electric and magnetic fields are perpendicular to one other (at right angles). They are likewise perpendicular to the EM wave's direction.

What is not a unique property of water
Answer:
Water molecules stick together by cohesion
Explanation:
This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.

What is the name of the gradient between high pressure and low pressure?
Answer:
Pressure gradient
Explanation:
Hope this helps :)
Answer:
Pressure gradient
Explanation:
The change in pressure measured across a given distance is called a "pressure gradient". The pressure gradient results in a net force that is directed from high to low pressure and this force is called the "pressure gradient force". The pressure gradient force is responsible for triggering the initial movement of air

Help please answer fast!!!
Answer:
A graph not only depends on the data that we are graphing, there are other important factors such as the units we use (here we have °C vs years, but we could have °F vs days and we would see a different graph, which represents the exact same information) , the scale we use (a lot of graphs are misleading because of the use of logarithmic scales, we need to be clear about the scales we use), where we put the zero of each axis (We usually use the intersection of both axes as the (0, 0) point, but this is not a necessary condition, we could manipulate our coordinate axis as we want) , etc.
So there are a lot of things that can impact on how we see the graph of the same data.
About the second answer, one could interpret from that graph that the actual temperature between the years 1880 and 2020 was around 14°C.

Write down only the correct name next to the relevant question number.
1.1 A protozoan which moves using its pseudopodia.
1.2 A protozoan which moves using its flagellum.
1.3 A filamentous green alga.
1.4 A unicellular green alga.
1.5 Microscopic protists which appear as symmetrical, human-made, and
glass-like ornaments.
1.6 Protists that look like fungi.
(6)
Answer:
1.1 Amoeba
1.2 Paramecium
1.3 Citations
1.4 Single algae cells
A protozoa that moves using its pseudopodia is an amoeba, one using its flagellum is Euglena and a filamentous green alga is Spirogyra. Chlamydomonas is a unicellular green alga. Microscopic protists that are symmetrical, man-made and appear as glass-like ornaments are diatoms while a protist that looks like a fungus is a mold.
What are Protists?A protist is a type of eukaryotic organism which is not an animal, plant, or fungus sharing a common ancestor. These are to the exclusion of other eukaryotes which means protists do not form a natural group or clade.
Protists are a group of diverse eukaryotic mainly unicellular microscopic organisms which share certain morphological and physiological characteristics with animals or plants or both.
Several protists showing different functions like an amoeba pushes out its cell membranes to form pseudopods. Euglena belongs to the class of protozoans known as flagellates. Spirogyra has a slender bright green color with a spiral shaped pigment that holds chlorophyll. Chlamydomonas is found in ponds, ditches and moist soil. Diatoms have a silky jewel-like covering. A mold is a protist which is a fungus.
Thus, a protozoa that moves using its pseudopodia is an amoeba, one using its flagellum is Euglena and a filamentous green alga is Spirogyra. Chlamydomonas is a unicellular green alga. Microscopic protists that are symmetrical, man-made and appear as glass-like ornaments are diatoms while a protist that looks like a fungus is a mold.

1: What gases are used and expelled by photosynthesis and respiration?
2: Where are the largest concentration of ozone and what value does it have?
3: What happens to the surface of the earth when there is an increase in greenhouse gases?
Answer:
1 Photosynthesis uses CO2 and expels O2 and the reverse for respiration
2. stratosphere where ~90% of it is
3. Less infrared radiation is able to escape from the earth into space and that infrared radiation hits the GHG gases and the radiation is turned into kinetic or heat energy trapping which warms up the earth
Explanation:
Answer:
1. Used by Photosynthesis: CO2 Expelled: O2
Used by Cellular respiration: O2 Expelled CO2
2. Most ozone (about 90%) is found in the stratosphere, which begins about 10–16 kilometers (6–10 miles) above Earth's surface and extends up to about 50 kilo- meters (31 miles) altitude. The stratospheric region with the highest ozone concentration is commonly known as the “ozone layer”
3. The surface of the earth heats up
Explanation:
From the top of the stiffer mantle to the center of earth, the rock material is inferred to be
(1) solid all way to the center of the inner core

)) If deer are not hunted legally every season, a potential result is(1 point)
A. the deer population will decrease.
B. the plant population will increase.
C. the predator population will decrease.
D, the smaller herbivore population will decrease.
The awnser is D because if we didnt kill deer there would be a increase in population and a decrease in the food they eat
Explanation
BRAINLIEST PLEASEIf deer are not hunted legally every season, a potential result is that the deer population will increase, not decrease, due to lack of control measures.
What are the various negative impacts for this condition ?This can have negative impacts on the ecosystem, such as overgrazing of vegetation and competition for resources with other herbivores. Additionally, an increase in the deer population can also lead to an increase in the predator population, as more predators may be attracted to the area to prey on the abundant deer.
If deer are not hunted legally every season, the deer population may actually increase. This is because hunting can be an effective way to control deer populations, and without it, there may be no natural predators to control their numbers. As a result, the deer may overgraze vegetation and compete with other herbivores for resources, leading to a decrease in the plant and smaller herbivore populations.
An increase in the deer population can also lead to an increase in the predator population, as more predators may be attracted to the area to prey on the abundant deer. This can have both positive and negative impacts on the ecosystem, as it may increase biodiversity but also lead to competition and potentially negative impacts on other species.
Overall, the management of deer populations is important to maintain a healthy and balanced ecosystem. This can involve regulated hunting, predator control, and other measures to control deer populations and minimize negative impacts on the ecosystem.
Therefore, the correct answer is not listed in the options provided, but of the options listed, the closest answer would be A. the deer population will decrease.
