Pedigrees have multiple uses. One of them is getting to know an individual's genotype. In the e xposed example, the individual IIIb is X-Y.
What is a pedigree?
A Pedigree is the representation of a family's history. This graph is used to track a trait through different generations, and analyze the inheritance pattern of a particular gene and its expression.
It is a tool used to understand how genes are transmitted from the parental generation to the descendants, and what are the probabilities of inheriting them.
In sex linked inheritance, we need to remember that the gene coding for the trait is linked to the sex-chromosome (in this case, the X-chromosome).
In pedigrees, usually affected individuals or individual carring the trait are representes with solid black figures.
Individual IIIb is a black square, meaning it is an affected man. Its genotype is X-Y. The X-chromosome is carrying the recessive allele (-).
In the attached files you will find the pedigree with the genotype of each member of the family. Notice that individuals X+X represent either homozygous dominant or heterozygous females.

By implementing biofuels and biodiesels, the town planner thinks that the public transportation emissions will be decreased 10 percent, from 3.15 metric tons to 2.84 metric tons! This, along with pledges from the community to decrease use of private transportation, will decrease emissions from 13.65 metric tons to 10.92 metric tons of CO2!
6. How many metric tons of emissions will be reduced per household if both of these plans succeed?
Answers
If both plans succeed, the reduction in emissions per household would be approximately 0.031 metric tons.
To calculate the reduction in emissions per household, we need to know the number of households in the town. Let's assume there are 1,000 households in the town.The reduction in emissions from public transportation is 3.15 metric tons - 2.84 metric tons = 0.31 metric tons. This reduction is spread across the entire community.Similarly, the reduction in emissions from decreased use of private transportation is 13.65 metric tons - 10.92 metric tons = 2.73 metric tons.To find the emissions reduction per household, we divide the total reduction by the number of households: (0.31 metric tons + 2.73 metric tons) / 1,000 households = 0.031 metric tons per household.Therefore, if both plans succeed, there will be a reduction of approximately 0.031 metric tons of emissions per household. This represents the collective impact of implementing biofuels and biodiesels in public transportation and decreasing the use of private transportation in the community.For more such questions on Emissions:

describe how impulse are transmitted across a synapse
Answers
A tiny electric message moves through a long part of a brain cell called the axon. When a message goes to the end of a nerve, it sends chemicals called neurotransmitters. These substances move through a tiny gap and attach to special parts of another nerve cell's outer covering.
What are the impulse?Messages called impulses are sent from one nerve cell to another through a connection called a synapse. This process is called synaptic transmission. Synapses are connections between nerve cells or between nerve cells and other cells, like muscles or glands.
The neuron sending the signal is called the presynaptic neuron. When a signal travels down a nerve cell, it causes little sacs called vesicles to release chemicals called neurotransmitters.

What is Mitochondrial?Mitochondria are organelles found in the cells of all eukaryotic organisms, which are responsible for generating most of the cell’s supply of chemical energy. They are often referred to as the “powerhouses” of the cell. Mitochondria are essential for life and are involved in a variety of cellular processes, such as metabolism, cell growth, and cell death. They contain their own DNA and can replicate independently from the cell. Mitochondria are also involved in several metabolic pathways, such as the tricarboxylic acid cycle, the beta-oxidation of fatty acids, and the synthesis of amino acids. Mitochondria are essential for life and have been linked to a variety of degenerative diseases, such as Parkinson's disease, Alzheimer's disease, and diabetes.

Methylene blue can be used to stain DNA because it: (2 pts) forms ionic bonds with DNA changes the pH and therefore the structure of DNA makes DNA electron dense is an effective chemical fixative for cells is none of the above
Answers
Answer: Methylene blue can be used to stain DNA of a cell because it (forms ionic bonds with DNA).
Explanation:
To examine the components of a cell usually under a microscope, a stain or dye is being used to provide a clear and defined view of the area under study.
The deoxyribonucleic acid (DNA) of a cell which contains the hereditary information of the cell is located in the nucleus.
Methylene blue is a type of stain used by biologists which helps them view microscopic life in brilliant color. It is a cationic stain (positively charged blue dye); and binds to negatively charged parts of the cells, such as nucleus (DNA) and RNA in the cytoplasm (with lower affinity).
When DNA of a cell comes in contact with methylene blue on a slide, their opposite charges attract, causing methylene blue's "rings" to slide in between the "rungs" of the DNA "ladder." As a result, a rich blue stain that identifies the location of the cell nucleus can be observed. This produces a photosensitive reaction which can then be viewed under the microscope.
Therefore is can be used to stain the DNA of cell because it forms ionic bonds with DNA.
The allele for the hair pattern called "widow's peak" is dominant over the allele for no "widow's peak." In a population of 2,000 individuals, 1020 show the dominant phenotype. How many individuals would you expect of each of the possible three genotypes for this trait?
Answers
1. Solve for q:
\(q = sqrt(1 - p^2)\)
2. Use the value of q to solve for p:
\(1020 = p^2 + 2p(sqrt(1 - p^2))\)
The Hardy-Weinberg equilibrium equation may be used to estimate genotype-specific population sizes. Use these notations:
Widow's peak: dominant allele frequency
q: Recessive allele frequency (no widow's peak)
p^2: WW genotype frequency
2pq: Heterozygous (Ww genotype) frequency
q^2: ww genotype frequency.
Since the widow's peak allele (W) is dominant over the no widow's peak allele (w), we may infer that p reflects the frequency of W and q represents w.
Since p+q = 1, we can compute q:
\(q= sqrt(1 - p^2).\)
We may suppose that 1020 people with the dominant phenotype (WW or Ww) have the WW and Ww genotypes:
\(1020 = p^2 + 2pq\)
Since the population is 2000,\(p^2 + 2pq + q^2 = 2000.\)

Zandile set up the following apparatus to investigate how temperature affects transpiration rate
Answers
Zandile found that as the temperature increased, the transpiration rate also increased, leading to increased water loss from the plant. This experiment helped her conclude that temperature directly affects transpiration rates.
Transpiration is the process of water movement through the plants from roots to leaves, and eventually lost by evaporation from the stomata. Various factors, including temperature, humidity, light, and wind, influence the transpiration rate.
Temperature affects transpiration as it affects the diffusion rate of water vapor from the leaves into the surrounding air.
To investigate how temperature affects transpiration rate, Zandile set up an apparatus comprising a potted plant, a beaker, and a thermometer. The plant was selected for the experiment, and its leaves were covered with a plastic bag to prevent any water loss through the leaves' surface.
The apparatus was set up in the following way: The plant was placed in a beaker containing water. The beaker was placed on a heat source, and the temperature was monitored with the help of a thermometer. The plastic bag was tied around the stem to ensure no air entered the plastic bag, making the experiment airtight.
Zandile then increased the temperature by placing the beaker on a heat source. She noted the temperature of the water in the beaker and the temperature inside the plastic bag. She continued to monitor the temperature and the rate of water loss from the plant.
