Which factor has the least effect on the strength of an electromagnet?
A. The length of the connecting wires
B. The number of coils of wire.
C. The material of the core.
D. The strength of the battery
Answer:
The answer is A. The length of connecting wires.
Explanation:
I took the quiz.
The length of the connecting wire has the least effect on the strength of an electromagnet.
What factors influence the strength of an electromagnet?An electromagnet is a type of magnet where an electric current creates the magnetic field. The wire that makes up an electromagnet is typically twisted into a coil.A magnetic field is produced by a current flowing through the wire and is concentrated in the hole, designating the centre of the coil.The type of core material, the strength of the current flowing through the core, the number of wire turns on the core, and the size and form of the core are all factors that determine an electromagnet's strength.Stronger magnetic fields can be created by using alloys like alnico, which is an alloy of aluminium, nickel, and cobalt.The strength of the electromagnet's magnetic field increases when:
(a) the current increases
(b) the number of turns increases
(c) the wire is wound so that the length of the electromagnet is reduced
(d) Soft iron core inserted into magnetic coil

The following are sources of Earth's internal heat energy EXCEPT
a. Decay of radioactive isotopes
b. Primordial heat
c. pressure from overlying layers
d. Sun’s energy
The sun's energy is not a source of Earth's internal heat. So the correct option is D.
What is the earth's internal heat?
Nobody has even gotten close to directly examining the interior of the Earth. So there is disagreement among geophysicists as to how heated the Earth's core is. However, the speed at which earthquake waves, sometimes known as "seismic waves," move may reveal a lot to scientists about the composition of the Earth.
The solidity, liquidity, or partial solidity of these materials can also be determined using seismic data. Laboratory results, meanwhile, show what pressures and temperatures the materials inside the Earth should melt at.
The temperature of the Earth's core is thought to be between 5,000 and 7,000 degrees Celsius based on this information. That is far colder than the sun's inside, yet roughly as heated as the sun's surface.
Although the amount of heat created inside the Earth is immense, the amount of heat energy received from the sun is around 5,000 times stronger. The weather is influenced by the sun's heat, which ultimately leads to erosion. It is so paradoxical that although the heat of the Earth creates mountains, the energy of the sun gradually breaks them down again.
Therefore the correct option is D.

The Nature Conservancy is an organization that protects a variety of habitats around the world. A project this organization would probably support is one that
Answer:
This question is incomplete but the completed question is below
The Nature Conservancy is an organization that protects a variety of habitats around the world. A project this organization would probably support is one that
(1) uses endangered animals for medical research
(2) protects the biodiversity of areas for future generations
(3) alters habitats for industry and housing
(4) prevents animal species from migrating to other habitats
The correct answer is (2)
Explanation:
Protecting habitats (which is the main "support" of this organization) will have to do with ensuring organisms live and are comfortable in the natural habitat they are found without or protected from "transgression" by humans and other possible biotic and even abiotic factors. Since, different organisms will normally live together in a community in order to "satisfy" the food chain and survive, this organization will most likely support projects involving the protection of biodiversity in different areas of communities of organisms for these organisms' future generations.
A person has a high fever of 105°F. State one effect that this high fever would likely have
on enzyme activity.
Answer:
The enzyme will change shape/denature, and stop activity
Explanation:
A person has a high fever of 105F. an effect that such a high fever would likely have on enzymatic activity is denaturing enzymes in the nervous system, possibly causing epileptic seizures.
What is the reason of high fever ?High fever (above 100F) is very dangerous for humans and can be fatal. One of the causes of this problem is the fact that high temperature modifies enzymes in the central nervous system which inducing the modification of the amino acid sequence of the enzymes.
With this given information, it is concluded that a person has a high fever of 105F. an effect that such a high fever would likely have on enzymatic activity is denaturing enzymes in the nervous system, possibly causing epileptic seizures.

If a limiting nutrient is supplied to the producer in the diagram above, what effect could it have on the birds?
Answer: The producers are the bluegrass. Adding a limiting nutrient to the grass would increase the amount of primary productivity. The result would be an increased amount of biomass at the producer level, and increasing biomass and available energy at each successive level. The number of birds could increase, because there would be more for them to eat.

B. The age of the dinosaurs
C. The hottest era
D. The era of humans
Answer:
The rise of life
Explanation:
A.P.E.X.
A description of the Paleozoic era is A. The rise of life.
What is the Paleozoic era?The Paleozoic Era was a geological era that spanned from about 541 to 252 million years ago. It is often referred to as the "Age of Invertebrates" because it was during this time that the first major diversification of animal life occurred, and most of the animal life was invertebrates.
This era also saw the emergence of fish, amphibians, reptiles, and the first land plants. The Paleozoic Era ended with the largest mass extinction in Earth's history, known as the Permian-Triassic extinction event, which wiped out about 96% of marine species and 70% of terrestrial species.
The Paleozoic Era is a geologic era that began about 541 million years ago and lasted until about 252 million years ago. During this era, there were several major events that shaped the Earth's history and led to the evolution of new life forms:
During the early part of the Paleozoic Era, there was a sudden burst of new life forms, including many of the major groups of animals that we know today. This is known as the Cambrian explosion.
Therefore, A) Paleozoic era, is the correct answer.

The mutation that causes color blindness is negative for many reasons. First off, not being able to see color can cause you to not be able to do certain things in life. For example driving, if you can't see the correct colors to know when to stop or go, you can't safely drive. There are also some jobs where colors are important. Such as jobs that have to do with fixing colored wire. It's also bad because of how it takes away one of our senses and holds us back from seeing things and completeness.
