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
For this cell division, you can see that 4 daughter cells are made that have half the genetic information as the original. What type of cell division is this?
a) Diffusion
b) Mitosis
c) Meiosis
d) Photosynthesis
Answer:
The cell division where 4 daughter cells with half of the genetic information of the original are obtained is meiosis (option c).
Explanation:
Meiosis is a type of cell division through which sex cells or gametes are obtained. It is a reductive division, since the daughter cells resulting from the process contain half of the chromosomal charge with respect to the original one.
In the process of meiosis, four haploid cells are obtained from a diploid cell, each of which is involved in the reproduction of the species. This mechanism of division occurs in two stages, called meiosis I and II.
The other options are not correct because:
a) Diffusion: it is a passive trans-membrane transport mechanism.
b) Mitosis: is the cellular division of somatic cells, where the result is two daughter cells identical to the original.
d) Photosynthesis: is the mechanism by which plants obtain energy and nutrients, from solar energy.

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.

A push or pull that an object experiences as a result of interacting with another item is known as a force. Every time two items interact, a force is exerted on each of the objects.
Therefore, 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.

O c. pollution of water
Answer:
C . pollution of water
Explanation:
In ecosystems, biotic an abiotic factors influence one another. Give three examples of an interaction between a biotic and abiotic factor in any of the marine ecosystems from the chart. (Use the back for more room).
Answer:
One of the most critical interactions in an ecosystem between the biotic and abiotic environment is photosynthesis, the base chemical reaction that drives most life on earth. Plants and algae use sunlight, water and carbon dioxide to create the energy they need to grow and live via photosynthesis.

The leaves of a plant absorb sunlight in order to help the plant undergo photosynthesis.
A plant with large, broad leaves would likely be able to absorb more sunlight than a plant with small, narrow leaves. The broad-leafed plant would therefore be better suited for living in an area that does not receive much sunlight.
Which plant would likely live in a shady area which only receives sunlight for a small portion of the day?
A.
none of these
B.
plant Z
C.

The rate at which molecules, such as water and oxygen, enter a cell is determined by the–
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).
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.
