what are the many forms of energy? how is energy either potential of kinetic
Answer:
The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.
You need energy to do any work, which is why the ability to do any work is energy. Read that again. Potential and kinetic energy are two forms of energy that can be converted into each other. Potential energy can be converted to kinetic energy and vice versa.

WILL GIVE BRAINLISTTTT!!!! In what ways are mechanical, chemical and biological weathering responsible for changes in our environment?
Answer:
Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble. Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock. If temperatures drop low enough, the water will freeze.

Considering the most important ecological issue of the future, what is the biggest challenge the world will face in its dedication to conservation and restoration in the future?
The number of species in an extinction vortex
Spread of disease and parasites via corridors
The amount of land and energy resources
The pressures of its growing population
Answer:
its the amount of land and energy resources or the pressure of its growing population.
Explanation:
It is likely that the biggest challenge the world will face in its dedication to conservation and restoration in the future will be the pressures of its growing population, which is the last option.
What is population growth?As the population grows, there will be an increased demand for food, water, energy, and land, which will lead to habitat loss, deforestation, pollution, and climate change. These factors can exacerbate other ecological issues, such as the number of species in an extinction vortex and the spread of disease and parasites via corridors. Therefore, it is crucial to address the root cause of these problems by promoting sustainable practices and reducing our impact on the environment.
Hence, it is likely that the biggest challenge the world will face in its dedication to conservation and restoration in the future will be the pressures of its growing population, which is the last option.

1. A cool piece of iron gets warm when a red-hot piece of iron is placed a few inches
away. How is heat transferred in this scenario?
Answer:
Convection currents in the air between the pieces of metal transfer all the heat. The air between the two pieces of iron emits thermal radiation that is absorbed by the cool iron.
There you go, hope this helped.
Heat energy is transferred from one matter to another through various modes and methods. A cool iron piece heats due to convection that transferred the heat from the hot iron.
What is convection?Convection has been one of the modes of thermal heat transformation that uses matter to transfer the heat from higher to lower concentrations, unlike the radiation mode. The matter particles move from hot to lower temperatures.
The air present between the cold and hot iron piece acts as the medium by which the cold iron piece absorbs the heat transferred by the hot iron piece. This thermal energy is emitted and absorbed due to the difference in temperature.
Therefore, the process of convection facilitates the thermal heat transformation from hot to cold iron objects.

Why is an imbalanced high population of moose on the island seen as a
problem? *
If the moose population continues to grow, they will run out of space on the island and
take over the wolf niche.
If the moose population is unchecked, the local balsam fir population will be
decimated, leaving a barren ecosystem.
It was not seen as a problem; science believes we should let the ecosystem run its
course and dies out.
It was not seen as a problem because the absence of wolves on the island ensured
the future of the ecosystem.
Answer:
If the moose population is unchecked, the local balsam fir population will be decimated, leaving a barren ecosystem.
Explanation:
The imbalanced high population of moose on the island seen as a problem because it decreases the local balsam fir population which is a major food source for the moose in the winter season. If the population of moose is grow higher then the scarcity of food sources occurs and the food source will be eliminated from that ecosystem. If the moose population increases the local balsam fir population will be eliminated from the ecosystem and the land will remain barren or without vegetation.

Explain why harmful mutations tend to disappear, while beneficial mutations become
widespread.
Answer:
Harmful mutations don't accumulate over time because they reduce the reproductive success of an organism! These mutations would be dead before they can produce any offspring, so there's a slim chance of their genes being passed on. (So it's basically like survival of the fittest, the ones that survive usually have beneficial mutations because that's what keeps them alive lol) Beneficial mutations play a big role in evolution too!

Explain how and why you would conduct a study to determine if this bone can be used to determine sex
Answer:
The pelvis is the best sex-related skeletal indicator, because of distinct features adapted for childbearing. The skull also has features that can indicate sex, though slightly less reliably. Males have a square jawline and the line between the outer edge of the jaw and the ear is vertical. Conversely, in females the jaw is much more pointed and the edge of the jaw slopes gently towards the ear.

Why is ocean acidification dangerous?2-3 complete sentences
Answer:
Carbonate is important to marine life, especially those with exoskeletons and shells, who form their protective casings from carbonate. Ocean acidification reduces the amount of available carbonate, and can cause their shells to crumble and dissolve. Animals then have to spend extra energy either repairing their shells or thickening them to survive.

Which scenario would result in a decrease in population size, or a negative population growth?
Use this formula:
population growth = (birth rate + immigration) – (death rate + emigration)
0 individuals emigrate, 14 individuals die, 14 individuals are born, 14 individuals immigrate
40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate
12 individuals emigrate, 5 individuals die, 17 individuals are born, 0 individuals immigrate
19 individuals emigrate, 4 individuals die, 25 individuals are born, 0 individuals immigrate
Answer:
The third situation has the lowest amount of people with 0.
Explanation:
In this situation,
0 individuals emigrate, 14 individuals die, 14 individuals are born, 14 individuals immigrate. Population growth = 14
In this one,
40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate Population growth = 2
For this one,
12 individuals emigrate, 5 individuals die, 17 individuals are born, 0 individuals immigrate Population growth = 0
Last one,
19 individuals emigrate, 4 individuals die, 25 individuals are born, 0 individuals immigrate Population growth = 2.

Describe how each of Newton’s laws may be observable during a car trip.
If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest. Additionally, if a car was moving straight when another car struck it, the direction of the car would shift.
What are newton's three law of motions ?According to the first law, until a force acts on an item, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction pressures upon one another.
There's a fourth law , it states that every object tends to remain in the state it is in right now. We refer to this propensity as inertia. Every object tends to remain in the state it is in right now.
Therefore, If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest (First law) . Additionally, if a car was moving straight when another car struck it, the direction of the car would shift (Third law).
