The components of a buffer and the role each plays in helping maintain a constant pH are acid-base and its salt.
What is a buffer?
A weak acid and its conjugate base, or a weak base and its conjugate acid, make form a buffer solution. When strong acids or bases are added, the pH balance of the two components remains stable.
A buffer is a solution that withstands any pH change when a little amount of both an acid and a base is added to it. The salt of the acid or base must be present for a solution to qualify as a buffer.
For an acidic buffer, acid and its salt with a strong or weak base are necessary ingredients. As an illustration, consider an acetic acid and sodium acetate solution.
For a basic buffer, a base salt with a strong or weak acid is a necessary component.
Thus, the components of a buffer are acid, base, and salts.

How does an individual with a competitive advantage lead to the evolution of an entire species?(1 point)
A) Some individuals are better at competing for resources, and that allows them to survive droughts or other major ecological events, leading to the extinction of certain species and the survival of others.
B) Traits that are advantageous help certain individuals reproduce at higher rates, so those traits are more common within the population.
C) Those who have traits that help them survive are able to reproduce, and their offspring have those traits, leading to a change in the species over time.
D) Individuals that survive due to their competitive advantage are able to expand their range, similar to how the finches radiated out from one common ancestor on the mainland.
Answer: the answer i belive it is; is D
An individual with a competitive advantage lead to the evolution of an entire species because : ( D ) Individuals that survive due to their competitive advantage are able to expand their range, similar to how the finches radiated out from one common ancestor on the mainland.
Evolution of speciesThe evolution of species is the change in the characteristics of species overtime and this is made possible through natural selection. Individuals with competitive advantage survives better than individual without competitive advantage therefore they lead to the evolution of species through natural selection by expanding their range.
Hence we can conclude that Individuals that survive due to their competitive advantage are able to expand their range, similar to how the finches radiated out from one common ancestor on the mainland.

If the left primary sensory cortex were damaged along the longitudinal fissure, a person could have trouble detecting sensation in the __________. If the left primary sensory cortex were damaged along the longitudinal fissure, a person could have trouble detecting sensation in the __________. tongue left hand right foot right buccal area
Answer:
right foot
Explanation:
The primary sensory (somatosensory) cortex is a region of the brain that receives nerve signals, which is located in the anterior part of the parietal lobe. The primary sensory cortex processes somatic sensory info from receptors for pain, pressure, touch, and temperature. The primary somatosensory cortex on the left side of the brain coordinates the sensory data of the right side of the body, while the primary somatosensory cortex on the right side of the brain coordinates the sensory data of the left side of the body.

the founder effect.
Answer:
founder effect
Explanation:
When a few individuals are isolated from the rest of the population and can have very different gene frequencies, it is called the Founder Effect. The founder effect is a type of genetic drift in which a small population is isolated. Due to this isolation, the population may have different gene frequencies than the rest of the larger population.

Suppose you travel to a tropical place like the Bahamas and watch the coastal poikilotherms, such as fish, crabs, and starfish, swim and crawl about in the warm waters. Suppose then that you travel to northern Maine and watch the related species of poikilotherms in the cold waters there. It would not be unreasonable to expect to see the animals in Maine moving about in slow motion compared to those in the Bahamas. In fact, however, rates of locomotion are likely to look to your eye to be more similar than different in the two places. Design experiments to assess whether the Maine animals are especially able to be active in cold waters. If you find that they are, how might their high ability for activity in cold waters be explained
Answer:
The correct answer is -
exposure of the opposite environments to the species and see if they are able to be active in cold waters.
If they are then species of organism in Maine and could have more ice-nucleating agents which are responsible for their high ability for activity in cold waters.
Explanation:
To test the assess if the Maine species of organisms are especially able to be active in cold waters an experiment can be designed where one needs to place the species or animals from Maine and Bahamas in reverse conditions.
Maine animals are placed in warm water environments and species from the Bahamas can be placed in cold water. Finding if they are able to adapt in reverse condition by calculating various processes and motion, if yes then it shows that it is not a special ability to survive in cold temps. However, if it is not then the Maine poikilotherms are specially designed for their environment. In case of yes then species of organism in Maine and could have more ice-nucleating agents
