Explain what the root cause of magnetic force is based on?
Explanation:
It is like 2 objects that have a charge in them with the same direction of motion which have a magnetic attraction between them.
Answer:
The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of motion have a magnetic attraction force between them.

Which is one characteristic of deep ocean currents?
Deep ocean currents move quickly.
Deep ocean currents are caused by winds.
Deep ocean currents move cold water toward the equator.
Deep ocean currents are affected by temperature but not by salinity.
Answer: Deep ocean currents are affected by temperature but not by salinity.
Explanation: I think it's this because I know it takes a while for deep ocean currents to move so it isn't the first one.
The characteristic of deep ocean currents is that deep ocean currents move cold water toward the equator.
The ocean currents can be defined as the continuous movement of seawater bodies in the ocean.These ocean currents move due to different forces that act upon the seawater body.The deep ocean currents occur in high latitude areas (e.g., Antarctic Bottom Water, North Atlantic Deep Water, etc) and move cold water toward the low latitudes (i.e., the Equator).In conclusion, the characteristic of deep ocean currents is that deep ocean currents move cold water toward the equator.

Number 4 about the river-horse is a hippo. River-horse is Greek for hippo.
What is Hippo?
The hippopotamus, also known as the hippos, hippopotamuses, or hippopotami (Hippopotamus amphibius), is a big semi-aquatic mammal that is indigenous to sub-Saharan Africa. It is sometimes referred to as the common hippopotamus, Nile hippopotamus, or river hippopotamus.
The hippopotamus is the largest terrestrial mammal after elephants and rhinos. Additionally, it is the largest living land artiodactyl.
The closest surviving relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from whom they separated some 55 million years ago, despite their morphological resemblance to pigs and other terrestrial even-toed ungulates.
Therefore, Number 4 about the river-horse is a hippo. River-horse is Greek for hippo.

2. How did Pasteur’s experiment with the flasks help disprove the idea that living things could just appear or come from nonliving things like water and air?
3. Why are nutrients needed for living things? Describe the difference between living and nonliving things.

how do you find out if something is alive or dead?
Answer:
In order for something to be classified as living, it must grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt. While many things meet one or more of these criteria, a living thing must meet all of the criteria.

Brainlist What causes water to condense on top of an aircraft's wing?
High pressure on front of wing forces water to condense.
Slower moving air on top of wing causes lower air pressure, cooling air.
Faster moving air on top of wing causes lower air pressure, cooling air.
Low pressure on the front of the wing causes water to condense.
Answer:
As the pressure above the wing, reduces, there is a sudden fall in temperature of the air above the wing. This sudden drop in air temperature, condenses the water vapor present in the atmosphere, above the wings. So, then the condensation clouds are formed above the wings.

Explanation:
According to the Cell Theory, all living things are made of cells. Therefore, C is the right answer.
A is incorrect. There are nonliving things that can still move. For example, cars are nonliving, but they are able to move.
B is incorrect. Although all living things do contain DNA, some viruses, which are not considered to be living organisms, also contain DNA. Therefore, only using this question will not accurately tell you if this specimen is living or nonliving.
D is incorrect. Many living things cannot make their own food. These organisms are called consumers.

Answer:
Homologous features
Explanation:
If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.
Answer:Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.
