The amount of light between points 1 and 2 is adequate for photosynthesis to occur at a faster rate than cellular respiration. Acidic conditions typically imply that the solution has an excessive concentration of H+, which makes the solution acidic. By dividing the reaction into half-reactions, the balancing process begins.
This indicates that more CO2 is being consumed than is being produced, which makes the problem more straightforward.
The signal will become purple as a result, from yellow. After point 2, light levels are low enough that cellular respiration outpaces photosynthesis, which results in more CO2 being generated than being absorbed and raising the pH of the solution. The indication will become yellow as a result, from purple.
An indicator dye called bromothymol blue (BMB) changes color from blue to yellow when acid is present. The pH of the solution decreases when carbon dioxide is introduced because it produces carbonic acid. When the pH is greater than 7.6, green, between 6.7 and 7.6, and yellow, less than 6, BMB is blue.

A box has a strong force pushing on it to the right and a weaker force pushing
on it to the left. The force from the ground and the force from gravity cancel
each other out.
What direction will the net force go?
Answer:
Left.
Explanation:
It will go left because, if the stronger force is pushing on the right, that means it'll go left. And then the weaker force is pushing on the left, so it will go right. So, if one force is stronger than the other, then the stronger force will be working more efficiently and it'll go the way that the stronger force is pushing.

a sensitivity analysis in a decision trees allows you to automatically change various parameter in a model and determine the corresponding impact on the result.
Sensitivity analysis is always a crucial element of decision making and decision trees often focus on probabilities.
Decision tree analysis involves visually outlining the possible outcomes, costs, and consequences of a complex decision. You can use a decision tree to calculate the expected value of each outcome based on the decisions and consequences that led up to it. Then, by comparing the results against each other, you can quickly assess the best course of action. You can also use a decision tree to solve problems, manage costs, and uncover opportunities. These trees are particularly useful for analyzing quantitative data and making decisions based on numbers. A framework was developed to perform sensitivity analyzes of optimal strategies that account for this distributional uncertainty. Sensitivity analysis determines how different values of the independent variable affect a particular dependent variable under a particular set of assumptions. In other words, sensitivity analyzes study how various sources of uncertainty in a mathematical model contribute to the overall uncertainty of the model.

describe how mutations, gene flow, nonrandom mating, genetic drift, and natural selection can cause changes in the frequency of an allele in a population by explaining how each violates the assumptions of the hwe.
Mutations, gene flow, nonrandom mating, genetic drift, and natural selection can cause changes in the frequency of an allele in a population
Define allele.
One of two or more variations of the DNA sequence (a single base or a segment of bases) at a certain genomic region is referred to as an allele. For any given genomic location where such variation exists, an individual inherits two alleles, one from each parent. An individual is homozygous for an allele if the two alleles are identical. The person is heterozygous if the alleles differ.
Alleles are added to a gene pool by mutations. As a result, the frequency of particular allele combinations in the population changes, leading to gradual population evolution. They play a significant role in the evolution of novel gene variants.
Gene flow is typically accompanied by a significant population and a gradual shift in gene frequencies. Genetic admixture is the gradual integration of the genes of migrant populations, each of which has its own distinctive allele frequencies, into the gene pool of the population into which they have migrated.
Although it can alter genotype frequencies, non-random mating won't change the population's allele frequencies on its own. Hardy-Weinberg equilibrium is prevented, but it's questionable whether this qualifies as evolution given that the allele frequencies are remaining constant.
Natural selection occurs when individuals with a particular genotype are more likely to survive and reproduce than individuals with a different genotype, and thereby to pass on their alleles to the following generation. There is variation in some traits among individuals within a population. This variant is inherited. Changes in this trait correspond to changes in fitness.
The sampling mistake that comes with individuals in a finite population transmitting gametes leads to genetic drift. Genetic drift is a process of evolution that is characterized by erratic changes in the prevalence of a particular gene allele in a population. The impacts of genetic drift can be severe, often leading to features in a community becoming overly prevalent or disappearing, even though it usually affects small, isolated populations.
