The Fourth Point (between 4 and 5)
You find the optimal pH by looking for the pH with the highest activity.
Explanation:
The optimal ph is basically where the enzyme has THE MOST activity.
The fourth point of the pH, and activity is the optimal pH because it has the most activity out of the nine points.

You are studying three populations of an endangered species of toad that used to be common in the California central valley. Global warming has caused this species to retreat to higher elevations in recent decades where it stays cooler; the toad used to be found throughout the valley, but is now restricted to the tops of three mountains. Historical records indicate that there used to be hundreds of thousands of toads in the central valley, but sampling the mountaintops reveals that the toad population on each is now limited to a few hundred individuals. You survey allozyme diversity at one locus on each of the three mountaintops and find that each population is fixed for a different allele of the ribbit gene: mountain #1 is fixed for the A1 allele, mountain #2 for the A2 allele, and mountain #3 for the A3 allele. The average number of baby toads born in each population is the same, and the environment on each mountaintop is very similar, as far as your data show.
Explain why each population is fixed for a different allele.
Sentence 1: Describe the variability that was initially present in each of the populations.Sentence 2: State which individuals had the highest fitness in a given population, or why fitness is not an issue if that is your conclusion.Sentence 3: Explain what evolutionary force acted on the population(s), and why and how it acted.Sentence 4: Describe how the populations evolved in response to their changing environment. Be as specific as you can (e.g., say "increased" or "decreased", rather than just "changed".)
Answers
Answer:
Explanation:
The allele are fixed because there is no variation that exist in the population and the allele are almost completely the same hence no new combination of gene the same Allele will continue to reoccur
Variability exist because of random mating that occurs in the population initially when the toad filled up the entire central valley
Random mating ensures fitness in the initial population
Genetic drift acted upon the population drifting away allele that are very few in population or that occur less in the population and perpetuating alleles that frequently occur leading to a fixed allele.
There was a decrease in the population as a result of the change in the environment.

This woman is riding a bicycle down a hill at a constant speed and in a straight line. Which change will increase the speed of the bicycle?
A. An added force of 20 N to the side of the hill B. Added forces of 30 N up the hill and 20 N down the hill
C. Added forces of 30 N up the hill and 30 N down the hill
D. An added force of 20 N down the hill
Answers
An added force of 20 N down the hill will increase the speed of the bicycle, stronger gravity is applied to things with higher masses, hence option D is correct.
What condition if a bicycle down a hill at a constant speed?A force that unites things. You stay on the ground thanks to the Earth's gravity, which also causes things to fall. Everyone and everything is affected by gravity.
Gravity is the force that pulls the cyclist down toward the ground. Riding the bike ahead on a completely level road encounters very little resistance from the effects of gravity.
Cyclist gains speed even when they are not pedaling because the potential energy produced by a hill's height is converted into an equivalent increase in kinetic energy.
Therefore, an added force of 20 N down the hill is correct.

Answers
Answer:
The chromosome contains all of the other options listed.
Explanation:
In eukaryotes, the complete chromosome is composed of only one lineal and extremely long DNI molecule. DNA is intimately associated with two types of proteins: histones, which are structural proteins, and non-histone proteins that mediate different functions of DNA. DNI associated with histones is called chromatin. Histones are responsible for packaging the DNI molecule.
In the interphase, before cellular division, chromatin is in a diffuse, lax, uncondensed state. When cellular division is about to happen, chromatin begins to condensate, and the chromatin strand generates a copy or clon so both of the daughter cells can get the same genetic information. At the beginning of the prophase, DNI is condensed in a well-defined chromosome formed by two sister chromatids. In metaphase, two chromatids joined by a centromere form the typical chromosome.
So, one chromosome is composed of two sister chromatids condensated and joint by the centromere. It looks X-shaped.
Genes are located in chromosomes, specifically in the DNA strand.

After Pedro had breakfast, he went for a run. Identify at least three energy transformations that had to take place to allow Pedro to complete his run. Then use evidence to support the claim that energy in this system was conserved as it was transformed.
Answers
1) Chemical to mechanical (calories -> muscle contractions)
2) mechanical to mechanical (muscle -> motion)
3) mechanical to thermal (motion -> heat from the body causes sweating)
The potential energy is stored in the body chemically (via food). That potential energy is then released when the body is put in motion.
Answer:
When Pedro ate breakfast, he consumed chemical energy. Chemical energy is a form of potential energy and that potential energy was stored in his breakfast. When he went out for a run, the chemical energy transformed into mechanical energy, which is a form of kinetic energy. The mechanical energy then transforms into thermal energy when he is running. While running his temperature started to rise which caused him to sweat. The energy in his system was conserved as it was transformed because the energy was constant. When the energy was being transformed between different types, the total amount of energy remained the same.

A plant is the most balanced need for water within its need for carbon dioxide and oxygen. It’s too much water is lost, the stomata will close. How does this affect the plants ability to regulate levels of carbon dioxide and oxygen?
Answers
Answer:
it helps regulate them and keep them level going through the state of transpiration
Explanation:
to prevent too much water lost a plant will close it's stoma to store that water, this process is called transpriation. if the stoma is open it will dry out the plant.
so a plant losing water in reaction they will close their stoma which is homeostasis, homeostasis is balance. so for example u go through homeostasis when it's hot outside it results in u sweating, why? cause your body is trying to cool down and regulate it's self.
