Because stress is a force, it... A) takes energy out of rock B) adds energy to rock C) adds volume to rock. D) makes rock harder.
Answer:
it adds energy to the rock
Explanation:
Because stress is a force, it adds energy to the rock. This stress/force is being applied to the rock. Whether the rock moves or not you are applying a force to the rock and it has potential energy. If the rock moves, you are adding energy to it and creating kinetic energy as the rock moves. Other forces such as gravity and friction can push against your force and prevent the rock from moving. Therefore, there are many forces at play in such a scenario.

Question 5
Some human cells can perform anaerobic respiration for limited amounts of time, such as during periods of heavy exercise. Use the results of your experiment to explain how anaerobic respiration could benefit human survival.
Answer:
My experiment showed that energy production, or respiration, occurred in yeast even when little oxygen was present. During exercise, the lungs must work hard to take in oxygen, which then circulates to the body parts that need it. The ability to preform anaerobic respiration for short periods of time allows humans to sustain activity, even when oxygen is limited in the body.
Explanation: from plato, so change it a bit.

The ability to preform anaerobic respiration for short periods of time allows humans to sustain activity, even when oxygen is limited in the body.
What is anaerobic respiration ?Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain.
In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is oxygen. Molecular oxygen is an excellent electron acceptor. Anaerobes instead use less-oxidizing substances such as nitrate (NO−3), fumarate (C4H 2O2−4), sulfate (SO2−4), or elemental sulfur (S). These terminal electron acceptors have smaller reduction potentials than O2. Less energy per oxidized molecule is released. Therefore, anaerobic respiration is less efficient than aerobic.

Which of these statements best describes a similarity between respiration and diffusion?
Both absorb carbon from the atmosphere.
Both release carbon into the atmosphere.
Both increase the level of carbon in the biosphere.
Both increase the level of carbon in the geosphere.
Answer:
Both release carbon into the atmosphere.Explanation:
Diffusion is the process whereby gases move from an area of high pressure to low pressure. This includes- Internal respiration - this is the movement in the internal tissues between cells and capillaries, and - External respiration - when gas is exchanged between the alveoli and lung capillaries. Perfusion refers to the blood flow to tissues and organs. Alveoli are perfused by capillaries so the diffusion of oxygen and carbon dioxide can take place.
Answer: Both release carbon into the atmosphere.

How is the ocean affected by the releasing of excess carbon?
Answer:
Explanation:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

reasons for seasons
Answer:
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. At different times of the year, the sun's rays hit different parts of the globe more directly. The angle of the Earth's axis tilts the Northern Hemisphere towards the sun during the summer. Without the tilt of the earth's axis, we wouldn't have seasons.

HELPPP ME
Carbon can also be harmful because a large amount of carbon is increasing the warmth of the earth. Carbon dioxide gas increases, lowering the pH of the ocean by the process called acidification, which is a threat to Ocean animals.
What is carbon?Carbon is an element or a substance that is present on earth in different forms full stop carbon is present in two forms on the earth, one is black and heart solid and one is gray and soft.
Carbon reacts with another element to produce different compounds, when carbon reacts with oxygen is produced carbon dioxide which is a very harmful gas for the earth and human beings.
Thus, as greenhouse gases are increasing including carbon dioxide the main threat to life and the earth is increasing of temperature which is melting the ocean and high temperature would not be best for all creatures.

Which type of reproduction results in variation of offspring?
Answer:
sexual reproduction
Explanation:
Compute the age of a basalt rock sample from the Moon containing 6 grams of Uranium-235 (parent isotope) and 42 grams of Lead-207 (daughter isotope). This rock is from a complex crater flooded with lava. The half-life of Uranium-235 is 704 million years.
Answer:
Age of rock = 21112000000 years
Explanation:
The half-life of a radioactive material is the time taken for half the original material to decay or it is the time required for a quantity to reduce to half of its initial value.
The ratio of parent isotope, Uranium-235 to daughter isotope, Lead-207 = 6 : 42 = 1 : 7
This means that for every one gram of the parent isotope, there are 7 grams of the daughter isotope. So,the quantity of radioactive material left is one out of eight its original value.
Number of half-lives undergone for 1/8 of the original value to to remain is given below:
1/8 = 1/2 × 1/2 × 1/2
Therefore, number of half-lives = 3 half-lives
Age of rock = half-life of Uranium -235 × number of half-lives
The half-life of Uranium-235 is 704 million years = 704000000
Age of rock = 704000000 × 3
Age of rock = 21112000000 years

148 deer per year
218 deer per year
307 deer per year
474 deer per year
Answer:
Option B, 218 deer per year

Where K is the carrying capacity
K is the rate constant
dP/dt is the change in population per unit time and
P is the population
Substituting the given values we get
[tex]\frac{dP}{dt} = k * 420 * (1-\frac{420}{875})\\= 1 *420 * (1-0.48)\\= 218[/tex]

Photosynthesis is the process by which energy is converted to chemical energy in plant cells. In cellular respiration plants use the chemical energy stored during photosynthesis in basic life processes. During both photosynthesis and cellular respiration, energy is converted. Plant management also relies on light-dependent and light-independent reactions of photosynthesis.
