Answer:
A. An increase in potential mates
Explanation:
An increase in potential mates would not be a potential result of a bottleneck event because it would actually increase the population rather than kill them off.
HAVE A GOOD DAY!!!!
Event an increase in potential mates is not potential result of a bottleneck.
What is the bottleneck effect for example?The bottleneck effect is an extreme example of genetic drift that occurs when the size of a population is severely reduced.
Events like natural disasters (earthquakes, floods, fires) can decimate a population, killing most individuals and leaving behind a small, random assortment of survivors.
Thus, option "A" is correct.

Imagine that y-axis of each graph describes the rate of photosynthesis. Which of the graphs represents the
effect of light intensity on the rate of photosynthesis?
a. A
b. B
c. C
d. D
Answer:
a. A describes the effect of light intensity on photosynthesis.
Explanation:
In plants and other primary producers, photosynthesis is a biological mechanism that is vital to energy production. Energy-containing carbohydrates are derived from light, water and carbon dioxide in the form of glucose molecules.
The waste product oxygen is released as a result. Photosynthesis depends on many variables, including:
carbon dioxide concentration, ambient temperature and light intensityIt is a rate-limited reaction. Since photons or particles of light provide the energy required for the reaction, high intensities of light increase the photosynthetic rate. From the graph shown, as the intensity increases steadily, so does the rate- but at too high of an intensity, it ceases to affect the rate of photosynthesis, which becomes constant or plateaus.
Beyond this point, either the supply of carbon dioxide or the temperature limits the reaction. For instance, at high intensities tissues may even be damaged by high temperatures or heat.
A solution that has 0% salt is____to a cell with 40% salt concentration
Answer:
The solution is hypotonic
Explanation:
Molecules in a solution move from highly concentrated regions to regions of low concentration in an effort to reach a state of equilibrium- where the molecules are equally distributed. This always occurs with the molecules moving down the concentration gradient.
Solutions can be:
hypertonic, or more concentrated; hypotonic- less concentratedisotonic- same concentrationAt 40% salt concentration, solution A is hypertonic while the less concentrated solution at 0% salt concentration is hypotonic.

How do you think plant cells differ from animal cells? (Hint: What can plants do that animals
cannot?)
Gizmo
Plants can create their own food and energy while animals cannot.
They can take energy from the sunlight, while animals have to take energy from either other animals or plants.
Plants spread seeds by water and wind and even animal fur, but animals have to move their kin themselves.
Animals can move far and quick, while plants cannot move except growing or leaning towards a certain thing, like sunlight.
Plants cannot see, they do not have eyes. Most animals can.
Animals mostly have voices or sounds of their own. Plants do not.
Animals have an anatomy full of organs and muscles and bones. Plants don't

you may have read about alkaline diets that claim that you need to only eat alkaline foods in order to remain healthy according to this philosophy eating acidic Foods acidifies the blood leading to disease but our blood has several buffer systems in place explain what happens when buffers encounter additional hydrogen ions from foods will the pH of the blood decrease
Answer:
Mechanisms are activated where it is sought to lower the amount of free protons in the blood, that is, to reduce acidity, these mechanisms work between two large systems, the receptor system, the respiratory system and the renal system.
Explanation:
When a metabolic acidosis is entered, either by a food, or by a disease or even an intense physical activity, the lungs seek to generate hyperventilation, to increase the concentrations of oxygen in plasma and absolutely decrease the carbon dioxide concentration, thus not the blood becomes even more acidic.
On the other hand, the digestive system together with the sensory system, will warn this proprioception of the acidity of the plasma and will promote the dilution of these acids with a solvent, which is water, promoting the sensation of thirst.
Finally, the kidneys will seek to retain all the alkaline solutes to neutralize the physiological internal pH, and will release through the urine and the channels of acidic compounds, the products or acid metabolites to the external environment, that is, acid urine excretion.

Answer: Oxygen, Lactic acid, liver, mitochondria
Explanation: Lactic acid fermentation occurs in muscle cells when OXYGEN levels are low. When LACTIC ACID builds up in muscles it causes pain and muscle fatigue. Usually, the lactic acid diffuses into the bloodstream over time and is filtered out by the LIVER and converted into glycogen and then to glucose. However, with proper training, lactic acid can transfer to the MITOCHONDRIA of muscle cells, where it is broken apart for its energy.
Lactic acid is produced as the byproduct of the anaerobic respiration. The correct answers are oxygen, lactic acid, liver, and mitochondria.
Lactic Acid Fermentation:
During the intense exercise, body become unable to fulfill the need of oxygen. Hence, body start producing energy anaerobic respiration and produce a by-product, lactic acid. This results in build up of the lactic acid in muscle which cause muscle fatigue.
Lactic acid fermentation occurs in muscle cells when Oxygen levels are low.When lactic acid builds up in muscles it causes pain and muscle fatigue.
