in what ways can overpopulation be beneficial to differential reproductive success?
Answer:
Differential reproduction is called the one that occurs as a result of the differences between the individuals that make up a society or sample, where it is those with comparative advantages who manage to reproduce, while those who do not have said advantages tend to die out. It is, in short, a practical application of Charles Darwin's theory of natural selection.
Thus, if there is an overpopulation of a certain species, a series of effects will occur (such as the scarcity of resources, the lack of living space, etc.) that will tend to gradually decrease the population to return to an ideal number of individuals. In this aspect, differential reproduction will be applied, being able to reproduce those that have comparative advantages over the rest, which will inevitably become extinct.

d. neurotransmitters that excite or inhibit a neural signal across a synapse
Answer:
d. neurotransmitters that excite or inhibit a neural signal across a synapse
Explanation:
Neurotramniters are molecules that transmit chemical messages from nerve cells by traveling across the synapse to target cells. Some of the most important neurotransmitters include acetylcholine, norepinephrine, dopamine, gamma-aminobutyric acid (GABA), glutamate, histamine and serotonin. Norepinephrine is a neurotransmitter synthesized from dopamine which is involved in the regulation of stress response, sleep, and blood pressure. Norepinephrine, also known as noradrenaline, is an important neurotransmitter involved in stress response and exercise. Finally, acetylcholine is a neuromodulator of the autonomic nervous system involved in attention responses, memory and motivation.

A. A star’s final stages of life depend on its mass.
B. Stars die when they run out of fuel.
Explanation:
A star's life cycle is determined by its mass. ... Over time, the hydrogen gas in the nebula is pulled together by gravity and it begins to spin. ... It is now a main sequence star and will remain in this stage, shining for millions to ... When the hydrogen supply in the core begins to run out, and the star is no longer supported.
When increasing the size of muscles or building muscle mass ____________. Group of answer choices muscle soreness indicates the muscles are growing delayed onset muscle soreness indicates the muscles are growing lactic acid build up triggers muscles to grow micro tears signal the muscles to grow
Answer:
A. soreness indicates the muscles are growing
D. micro tears signal the muscles to grow
Explanation:
Muscle soreness is one of the indication of muscles are growing as while doing exercise, some inflammation takes place to get bigger and stronger muscles. Some pain signals are sent by the body to make it feel soreness after intense exercise.
Micro tears signal also indicates muscles growth as after intense workout, a certain amount of soreness is felt by our body and these micro tear signals to repair and replenish the muscle tissue that eventually accumulate to form muscle mass.
Hence, the correct answers are: "A. and D.".

Which example best demonstrates diffusion?
A. cellular movement
B. an amoeba engulfing a bacterium
C. the dispersal of dye in a beaker of water
D. a contractile vacuole removing excess water
A contractile vacuole removing excess water is the correct answer.
What is diffusion?Diffusion is defined as the movement of particles from a region of high concentration to a region of lower concentration. Diffusion occurs in both liquids and gases which is an important process for living organisms.
In contractile vacuole, water moves from higher concentration region to lower so we can conclude that a contractile vacuole removing excess water is the correct answer.

What causes the earths tides; describe the conditions for the largest tides?
Answer:
Earth's rotation and the gravitational pull of the sun and moon create tides on our planet. Because the sun is so much larger than the moon (27 million times more masssive), it has a much bigger graviational pull on Earth.
Plzzz help with the one with the membrane picture
Answer:
1.) The solute molecules will not move between the two sides because the membrane does not have large enough spaces for the molecules to move through. The water molecules will move to the right side because water moves to places of a higher solute concentration.
2.) The right side represents high concentration because it contains the majority of the solute molecules.
3.) The left side represents low concentration because it contains a small amount of solute molecules compared to the right side.
the process of living organisms staying the same
Answer:
Explanation:
All species of living organisms, from bacteria to baboons to blueberries, evolved at some point from a different species. Although it may seem that living things today stay much the same, that is not the case—evolution is an ongoing process. The theory of evolution is the unifying theory of biology, meaning it is the framework within which biologists ask questions about the living world.
Answer:
Living organisms have an ability to keep a stable internal environment and they maintain to have a balance inside their cells.
Explanation:
Reproduction is the process by which organisms make more of their own kind from one generation to the next.
Metabolism is the sum of all the chemical reactions carried out in an organism. heredity is called a gene.
as a cell's size increases, what happens to the ratio of its surface area to its volume?
A:the ratio stays the same
B:the surface area increases as the volume increases
C:the surface area does not increase as fast as the volume increases
D:the ratio of surface area to volume does not matter
Answer:
Surface Area to Volume Ratios: Notice that as a cell increases in size, its surface area-to-volume ratio decreases. When there is insufficient surface area to support a cell's increasing volume, a cell will either divide or die.

The layers of the earth are differentiated based on their composition and occurrence. The crust is 6 -70 km thick, and the mantle is where the convection occurs. Thus, the matches are 1. c, 2. d, 3. b, and 4. a.
What are the layers of the earth?Earth has many different layers based on their arrangements and occurrences. The crust is the first layer of the earth where humans and other organisms live and ranges from 6 -70 km thick. It is followed by the Moho barrier.
The Moho barrier is the layer that separates the crust from the mantle and is followed by the mantle layer where the convection in the tectonic plates leads to earthquakes.
The deepest and the innermost layer is the core where the solid and liquid hot gases are found at very high temperatures. It is very hot and composed of iron and nickel.
Therefore, the matches are 1. c, 2. d, 3. b, and 4. a.
