Answer:
Buffers are substances that help resist shifts in pH by both donating H⁺ and accepting H⁺ (option D).
Explanation:
A buffer is a chemical substance capable of balancing the pH of a solution, when the balance is altered by the addition of an acid or a base. They are also called cushioning solution, and can be formed by an acid and its base conjugated, with a specific range of action.
The presence of a buffer in a solution has the ability to release hydrogen ions (H⁺) or accept them, helping to balance the pH, in the presence of a base or an acid, respectively. That is, a buffer can yield H⁺ to a solution when there are few or accept H⁺ when its content is high.
The other options are not correct because:
A. Buffers do not release H+ into a solution when acids are added, but accept them.
B and C. Giving up H+ to a solution when bases are added or accepting H+ from a solution when acids are added are effects that buffers can potentially do, which is described in the text above.

Which statement best describes why the population growth rate slows as population size approaches carrying capacity?
O reproduction increases
O predation rates decrease
evolution of traits decreases
competition for resources increases
Answer:
competition for resources increases
Explanation:
When an ecosystem reaches its carrying capacity, competition for scarce resources become more intense.
The result of this is that species will either begin to die, or migrate away from the ecosystem leading to a decrease in population growth
A scientist investigates two types of cells located in different parts in the
human body. Cell A contains many more mitochondria than Cell B. What is
the best conclusion to make from this observation?
o O
A. Cell A produces more protein than Cell B
O
B. Cell A has a larger vacuole than Cell B.
C. Cell B does less work than Cell A.
O
D. Cell B creates more energy than Cell A.
Answer:
The best explanation regarding the observation of more mitochondria in cell A than in cell B is that cell B does less work than Cell A.
Explanation:
Mitochondria are the organelles in charge of energy production in the cell. Tissues with high energy demand, such as striated muscle, have cells with a large amount of mitochondria, to satisfy this requirement.
According to the observation, if the cell B has less work than the A cell, its energetic demand is lower and the consequence is a smaller quantity of mitochondria in its cytoplasm.
The other options are not correct because:
A and B. The fact that the A cell has more mitochondria is not related to protein synthesis or having larger vacuoles.
D. Cell B does not produce more energy than Cell B because it has fewer mitochondria.
C) Explain the difference in how the plant and the woman get glucose molecules to use for energy
Answer:
Ok:
Explanation:
The woman eats and digests food to get glucose while the plant can undergo photosynthesis which forms glucose.
The plant and the woman utilize different mechanisms for accumulating glucose in their body to use for energy.
What is Glucose?Glucose may be defined as the main type of sugar in the blood which provides immediate energy to the body's tissues to perform metabolic activities.
Plants utilize the process of photosynthesis to construct their food
(glucose) with the help of carbon dioxide and water in the presence of sunlight, while the woman eats food products which are then digested into the stomach, and glucose is synthesized which is then transported into the bloodstream.
Therefore, it is well described above.

3. What are 3 examples of proteins and what functions do they serve in organisms' bodies?
Answer:
ADN, ARN and Cytoplasma
Explanation:
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. ... After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm.
Answer:
HORMONES are chemical-signaling molecules, usually small proteins or steroids, secreted by endocrine cells that act to control or regulate specific physiological processes, including growth, development, metabolism, and reproduction. For example, insulin is a protein hormone that helps to regulate the blood glucose level.
ENZYMES which are produced by living cells, are catalysts in biochemical reactions (like digestion) and are usually complex or conjugated proteins. Each enzyme is specific for the substrate (a reactant that binds to an enzyme) it acts on. The enzyme may help in breakdown, rearrangement, or synthesis reactions.

explain how animal cells differ from plant cells with respect to the effects of net water movements
Answer:
Terms in this set (4) Animal cells do not have a cell wall, meanwhile plant cells do have a cell wall. As a result, water passes freely in an animal cell due to osmosis. In a hypotonic solution, there is more free water outside the cell than inside the cell.

If the object shown has a mass of 80g, what is the density?
Answer:
C. 1.23 g/ml
Explanation:
[tex] Density = \frac{Mass}{Volume} [/tex]
Mass of rock = 80g
Volume of rock = final fluid volume - initial fluid volume
Volume of rock = 265 cm³ - 200 cm³ = 65 cm³
[tex] Density = \frac{80g}{65 cm^3} [/tex]
[tex] Density = 1.23 g/cm^3 [/tex]
1 cm³ = 1 ml
Therefore, density of the object = 1.23 g/ml

Lori is a vegan who believes she gets all the nutrients she needs from her diet. She has never taken supplements, even when she was pregnant. Her baby, Mason, was born full-term, but with a small portion of his spinal cord protruding through his vertebrae, resulting in partial paralysis of his legs. This neural tube defect, called , may have been caused by Lori's insufficient intake of during pregnancy. This micronutrient is necessary for regenerating the active form of .
Answer:
The condition is called "Spinal Bifida", caused by lack of vitamin B12 which helps regenerate the active form of folate.
Explanation:
Because Lori is a vegan, her vitamin B12 intake which comes from animal products such as meat, is not enough. She has to take supplements to make up for the lack of it in her diet.
As stated in the question, this lack of vitamin B12 causes her child to have a defect in his spinal cord called Spinal Bifida that defines a spinal cord or spine that has not fully developed. The vitamin B12 is necessary for regenerating the active form of folate.
