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

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.

Why is the attraction that particles have for each other not enough to keep gas
particles close together?
Answer:
Kinetic energy is needed to overcome the force of attraction between particles of the same substance. In solids, particles don't have enough kinetic energy to overcome the force of attraction between them. The particles are packed closely together and cannot move around

A) 2,000 kilometers
B) 4,600 kilometers
C) 1.5 million kilometers
D) millions of kilometers
Answer:
D) millions of kilometers
Explanation:
The sun's corona extends million of kilometers into space from the sun outward.
The corona of the sun is one of the layers of the sun with blistering plasma extending into the space. It extends several million of kilometers away into the solar system. This layer has a whooping temperature of about 2-5million degree Celsius.
It is the light and energy conveyed through the corona that furnishes all the planets with radiant energy.

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.

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.

When the viral DNA becomes active in the lysogenic cycle, which life cycle does it enter?
A.lytic
B.lysogenic
C.cell cycle
D.DNA replication
Answer:
A.lytic
Explanation:
Lysogenic and lytic cycles are two cycles of viral reproduction. In the lysogenic cycle, the viral DNA is incorporated into the host cell genome. Then, it can be passed on to the cell's daughter cells after it divides.
The other cycle of viral reproduction is called the lytic cycle. In the lytic cycle, the DNA is activated (transcribed). Viral particles can then assemble and replicate, and lyzing the host cell.

What specialized structures in flowering plants increase the probability of
successful reproduction?
Answer:
There a few structures that can increase the chances of successful reproduction; 1) Brightly colored flowers that attract butterflies, bees, and hummingbirds which are pollinators, 2) Fragrant odors emitted from said flowers, and 3) Nectar that is consumed by pollinators.
The flowers are a source of food and nectar on which the bees feed on these bees tend to pollinate and help in the germination of new flowers as they are agents of pollination
Except that winds are also responsible for the successful reproduction. The factors that determines the successful reproduction is based on the color of the flowers. Such as more bight and vibrant flowers favors more reproduction. These flowers attract insects, butterflies, and birds.Hence the bright flowers are the answer.
