You are replicating Gregor Mendel's famous experiment with sweet peas. The genotype for dominant smooth-seeded parent is designated AA, while the genotype for the wrinkled-seeded parent is aa. Using a punnet square predict the first generation for this cross. What are the genotypic and phenotypic ratios? SHOW ALL WORK.
Answers
Answer:
The correct answer is -
A. genotype ration = 1/1 or 100% of Aa.
B. phenotype = all smooth-seeded.
Explanation:
According to the question, in this experiment, the smooth seed is the dominant trait over the wrinkled seed. The wrinkled seed is recessive, therefore, represented by aa and dominant is represented by AA
gametes: A and A from smooth seeded parent and a and a from the wrinkled-seeded parent.
Punnett square:
A A
a Aa Aa
a Aa Aa
In this cross of F1 generation, all the offsprings are Aa in genotype 4/4 or 1/1 or 100 percent chances.
And phenotypically 100% chances of the smooth seed plants.
Watch the seven minute video on the "Mystery of the Buffalo boom" on you tube. Write a reflection on how scientists used their reasoning skills to make a claim about causes of the "buffalo boom".
Answers
Answer:
In the "Mystery of the Buffalo boom" scientists first try to find the answer in the two most common things that can affect a population of animals. Food and predators.
First, they studied the buffalos' food supply, grass. They found that there has not been an increase in it so that the number of buffalos multiplied.
Then they studied the predator's population, and they found that there was not a decrease in the number of them that could affect the buffalos increasing numbers.
As the two main things that controlled a population were not affected, they had to find other causes. The next thing that they studied were historical facts about buffalos and diseases. Scientists discovered that a virus that affected cows had impacted these animals too, which was the cause of a considerable decrease in the buffalo's population many years back.
Due to the drastic impact that the rinderpest had on cows, a vaccination plan was implemented. As the cows now were protected against this virus, the virus could not reproduce as it did, ending the spreading of this disease in cows. As a consequence, the buffalos were no longer infected, and their population grew thanks to the vaccination plan.
In conclusion, when the most common things that can affect a population are not the cause, we have to look into the past and find what has changed and how it impacted the animals. It is using logical thinking skills to determine what has changed and what that change made.
Explanation:
In the video "Mystery of the Buffalo boom" the ecologist Tony Sinclair found an abnormal buffalos' number in Tanzania. As the increase in the buffalos' population was something unusual, he knew that something had changed, but he did not know what. Sinclair, with other scientists, used their reasoning skills and thought that the two most logical things that can affect a population are food and predators. When they studied these two variables, they found out that they were not the problem. The next step was to look for past events that impacted buffalos. They found out that a virus, which directly affected cows but also buffalos, had been erased from the Earth thanks to a vaccination plan. As a result, the disease spreading between cows stopped, and as a consequence, it also stopped between buffalos.
We can see that everything is connected and that by using reasoning skills and logic, scientists could determine what happened.

Answers
Answer:
he special characteristics that enable plants and animals to be successful in a particular environment are called adaptations. Camouflage, as in a toad's ability to blend in with its surroundings, is a common example of an adaptation. The spines on cycad leaves, keep animals from eating them.
Explanation:
Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.

A population ecologist wished to determine the size of a population of white-footed deer mice, Peromyscus leucopus, in a 1-hectare field. Her first trapping yielded 80 mice, all of which were marked with a dab of purple hair dye on the back of the neck. Two weeks later, the trapping was repeated. This time 75 mice were trapped, out of which 48 of the mice were marked. Using the formula below, what is the population of mice in the field
Answers
Answer: 125
Explanation:
Population size is the number of individuals in a population. First, the trapping yielded 80 mice that were marked. Two weeks later, 75 mice were trapped and 48 of them had the mark.
The formula used for this question is:
N=mn/x
N= population size in the 1-hectare field. m= number of individuals marked and released the first time. n= number of individuals captured the second time. x= number of marked individuals that are recaptured.
The experiment consist on a randome collect sample of individuals which are then marked and released. Next, take a sample again.
So, replacing the values we get:
N=(80)(75)/48
N=125 individuals.

How is your body temperature held constant despite different weather temperatures
outside?
Answers
Answer:
Core body temperature The body can only stay at a constant temperature if the heat generated is balanced and equal to the heat lost. Although the core temperature must be close to 37°C, fingers and toes can be colder. This is because energy is transferred from the blood as it travels to the fingers and toes.
Answer: When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.

----------
Wind 15°C
15°C
What were the conditions before Storm 2, and why did more rain fall with those conditions?
Answers
Answer:
Before storm 1 occurred the air parcels were most likely more warmer hence the Rainfall was higher in storm 1 but before storm 2 the air parcels moved further and lost some energy
Explanation:
Given the temperatures of the areas before storm 1 and storm 2 have the same temperature 15°C and the same amount of wind blew across the areas just before the storms ( storm1 and storm 2 ) occurred.
Hence the conditions before storm 2 that could have caused more rainfall in storm 1 can be attributed to varying atmospheric conditions like; before storm 1 occurred the air parcels were most likely more warmer hence the Rainfall was higher in storm 1 but before storm 2 the air parcels moved further and lost some energy
