The mass of a proton is the same as the mass of a neutron
True or false
Answer:
This statement is true.
Explanation:
Both protons and neutrons have a mass of one.
Hope this helps :)
Answer:
The proton and neutron have similar mass with the mass of the neutron slightly larger than that of the proton. Each of these particles has a mass approximately 1800 times greater than that of an electron. ... The atomic number of an element is equal to the number of protons in the nucleus of an atom of that element

Explain "Survival of the Fittest" and how it
relates to natural selection.
Answer: Natural selection is selection due to environmental conditions from random genetic mutations in a population. Among the variants in a population, some will be slightly better adapted to conditions and will eventually out-compete the rest of the population. Survival of the fittest actually means survival of the best adapted, or fittest for purpose, i.e. to survive and thrive.
Explanation: This phrase has caused much miunderstanding of the evolutionary process. ‘Fittest’ has been equated with biggest, or strongest or fastest, but this was a description originating in the nineteenth century, when it was understood quite differently.
Natural selection arises from genetic variation in a population. Jaques Monod, an esteemed scientist, described evolution as where chance and opportunity meet. Chance lies in the genome of a species, random mutations, and the resulting genetic variation in the population.
Opportunity lies in the environment. Environmental change creates opportunities for some, extinction for others. Opportunities can also be from exploiting new environmental niches.
Natural selection is the process by which some random genetic variation gives some of a population a competitive advantage. competition eventually results in one population out-competing all others in its niche. The end-result of competition in nature is monopoly.
But this process continues and further random mutations can result in another population becoming better adapted. That is the actual meaning of survival of the fittest: in modern terms we might say ‘fittest for purpose’, that is, the species orvpopulation best adapted to survive and thrive in that environment.
1.In what way are gases different from solids?
A.Gases are madebof atoms; solids are made of molecules
B. Gases dont have a fixed shape:solids do
C. Gases have particles that are closer together than thoes in a solid
D. Gases partical have less energy than solid paeticals.
Answer:
B: Gases dont have fixed shape, solids do
Explanation:
A is false because gases and solids can be both made up of atoms and also molecules
B is true because gases do not have definite shape or volume, while solids have definite shape and volume
C is false because particles of a gas are farther apart under similar pressure, volume and temperature as particles of a solid
D is false because gases have more energy than solid particles under similar pressure, volume and temperature due to their movement they are constantly transfering energy from one particle to another as they move
Answer:
Explanation:A: the atoms in a gas move at high speeds
C: the atoms in a gas spread in all directions
Methylmercury biomagnifies in an ecosystem, meaning its concentration __________ as it moves through each higher trophic level.
A. equalizes
B.does not change
C. decreases
D. increases
Answer:
D - Methyl Mercury Increases
Explanation:
The word Biomagnification has a simple explanation:
To magnify is to make bigger, meaning that the substance in question is becoming more abundant.
The "bio" part of this word is referring to the fact that it is a biological substance you are dealing with.
Question: "Methylmercury biomagnifies in an ecosystem, meaning its concentration __________ as it moves through each higher trophic level."
Answer: "The concentration of the methylmercury increases as it moves through each higher trophic level. Hence, the methylmercury biomagnifies in the ecosystem. So, based on the options given prior to the question above, Option D) increases would be your best bet."
PLEASE HELP!!!! 30 points!!!! Start a discussion on Homeostasis. List 2 facts and 2 opinions.
Answer:
facts: The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.
opinions: Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment. Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.
Explanation:
Answer:
Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment.
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.
In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.
Biological systems like those of your body are constantly being pushed away from their balance points. For instance, when you exercise, your muscles increase heat production, nudging your body temperature upward. Similarly, when you drink a glass of fruit juice, your blood glucose goes up. Homeostasis depends on the ability of your body to detect and oppose these changes.

How will water volume, incline gradient, and temperature affect the energy
of a stream?
Answer: Water Volume: The volume of water(discharge) in a stream affects the energy(velocity) of that stream. As the volume of the water in the stream increases, the velocity increases. ... Incline gradient: The incline gradient is also known as the slope of the stream.

Answer:
Explanation:
Cell membranes act as barriers to most, but not all, molecules. Development of a cell membrane that could allow some materials to pass while constraining the movement of other molecules was a major step in the evolution of the cell. Cell membranes are differentially (or semi-) permeable barriers separating the inner cellular environment from the outer cellular (or external) environment.
Water potential is the tendency of water to move from an area of higher concentration to one of lower concentration. Energy exists in two forms: potential and kinetic. Water molecules move according to differences in potential energy between where they are and where they are going. Gravity and pressure are two enabling forces for this movement. These forces also operate in the hydrologic (water) cycle. Remember in the hydrologic cycle that water runs downhill (likewise it falls from the sky, to get into the sky it must be acted on by the sun and evaporated, thus needing energy input to power the cycle).

What is a push or pull that can cause motion known as
Answer: A force is a push or a pull that causes an object to move, stop, or change speed or direction. Every time you push or pull something you apply a force. Forces transfer energy.
Explanation: In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
