Describe the motion of the molecules in the cold water in terms of their kinetic energy.
Answer:
As ice melts into water kinetic energy is being added to the particles.This causes them to be "excited" and they break the bonds that hold them together as a solid resulting in a change of state:solid -> liquid.
Red-eyed tree frog eggs can hatch up to two days earlier than average when they detect vibrations. However, if they hatch more than two days earlier than expected due to vibrations, the embryos are typically not developed enough to survive outside of the egg. Explain how natural selection inhibited frog eggs from hatching any earlier than two days before expected hatching. Explain your answer in 1–2 sentences.
Natural selection inhibited the eggs from hatching before expected because this trait is negative in terms of survival and reproduction.
How does natural selection work?Natural selection is a natural process that causes evolution over time. This mechanism implies only individuals with traits that represent an advantage for survival and reproduction will prevail over time, which causes the traits of these individuals to become dominant.
For example, if in a population of deer male deer with big antlers are more likely to survive and reproduce, it is expected after some generations this trait is dominant.
How does natural selection work in the red-eyed tree frog case?In this situation, we know that if an egg hatches before time the embryo is not likely to survive. This means this trait is a disadvantage in terms of survival and reproduction, and due to this and as a result of natural selection the trait is not dominant.

describe how the position of the Earth Moon and Sun can be detected on Earth
Answer:
As the Earth rotates, it also moves, or revolves, around the Sun. As the Earth orbits the Sun, the Moon orbits the Earth. The Moon's orbit lasts 27 1/2 days, but because the Earth keeps moving, it takes the Moon two extra days, 29 1/2, to come back to the same place in our sky.

The amount of energy required to heat 0.5 kilograms of water until the temperature increases 12° C is about
Answer:
Q = 25104 / 4.184 = 6000 Calories or 6 Kcal
Explanation
Energy can be calculated by the equation
Q = m x Cp x delta T
where
m = mass = 0.5 kg
Cp = specific heat of water = 4184 J
Delta T = 12 degrees
Multiplying all
Q = 0.5 x 4184 x 12 = 25104 Joules
Converting it to Calories
Q = 25104 / 4.184 = 6000 Calories or 6 Kcal

Why does the mitochondrial gene tree suggest a later split? Why the disparity between the nuclear gene tree?
this is the link: https://learn.genetics.utah.edu/content/evolution/bears/
Answer:
Why does the mitochondrial gene tree suggest a later split?The mitochondrial gene tree suggests a later split because it occurred hybridization later in time, with the transference of the brown bear mitochondrial genetic information to the polar bear population. So the mitochondrial gene tree exhibits a later divergence.
Why the disparity between the nuclear gene tree?Because the first divergence event of the common ancestor occurred 60,000 years ago, evidenced by nuclear DNI and mitochondrial DNI. However, 100,000 years ago, concerning the mitochondrial genetic material, the hybridization event defined a new more recent common ancestor between the two species.
Explanation:
The use of mitochondrial DNA might present a few problems that need to be considered in evolution studies. It involves only one locus, so it has some limitations when reconstructing history, especially if the locus went through any process, such as natural selection, bottleneck events, or its transference to another population due to hybridization. There is also a high possibility of an incomplete reconstruction of the population history if males and females have different dispersal patterns.
The most proper way of reconstructing history is by complementing mitochondrial information with nuclear genetic information and evaluating their concordancies.
In the exposed example, 600,000 years ago, the original species split into the polar bear and the brown bear. But 100,000 years ago, hybridization occurred between a brown bear female and a polar bear male. The offspring joined the polar bear population, carrying the female genetic information, nuclear and mitochondrial. With time, these individuals interbred with the polar bears, diluting the nuclear brown bear genetic information. However, females carrying the brown bear mitochondrial DNI seemed to be more successful reproductively than the polar bear females. The mitochondrial information, hence, has been in the population for many generations, until today. And this information came from a more recent common ancestor, compared with nuclear genetic information.

When an object is already in motion, why is energy required to stop it
When an object is already in motion then we require force to stop it because due to inertia , a body tends to remain in the state of motion unless an external force acts on it .This is in accordance with Newton's first law of motion or law of inertia of motion.
What is inertia ?Inertia is the tendency of a body to remain the way it is. It opposes any changes to its state of rest or motion.
The more is the mass of the body , the greater will be the inertia.
What is external force?External force is the force applied by external agents on the body.

Answer:

a person who is among the first to study or develop something
Explanation:
Pioneer species are hardy species which are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire.[1] Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants
Why are food webs more realistic than food chains?
There are more animals
Most organisms eat more than one thing
Most organisms eat each other
Most organisms live on their own
Answer:
The correct answer is -most organisms eat more than one thing.
Explanation:
Food chains are the linear representation of easier visualization of trophic levels or movement of energy through the ecosystem. However, in reality, consumers can depend on more than one producer or other consumers for their food, and energy and interaction among these organisms are not that simple as it shows in the food chain. This makes the food webs to be more realistic than simple food chains.
The food web gives a better idea of the complexity of the various components and movement of energy in an ecosystem because the food webs is are the representation of interaction and interrelation of many different consumers and producers in an ecosystem.
Which of the following is the best definition of Newton's theory of universal gravitation?
Every object is pulled downward with a force that increases as the height from which an object is dropped increases.
Every object is attracted to the Earth with a force that increases with increasing mass and distance.
Every object attracts every other object in the universe, with a force that increases as the objects' masses decrease and the distance between them increases.
Every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
the answer would be D!;
every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
The definition of Newton's theory of universal gravitation is : ( D )
Every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
Newton's theory of universal gravitation states that "every object attracts every other object in the universe with an attracting force that is proportional to the product of their masses and is inversely proportional to the square of their distances "
Therefore based on the Newton's theory of universal gravitation the best definition from the options given above is Every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
Hence we can conclude that Every object attracts every other object in the universe, with a force that increases as the objects' masses increase and the distance between them decreases.
