Parent 2:Ff. Ff

Phenotype ratio:

0 for long fur

4 for short fur



Parent 1: Ff

Test 2

Parent 2: Ff


FF. Ff

Ff. Ff



Phenotype ratio: 1 for long fur and 3 for short fur



Test 3

Parent 1: ff

Parent 2:ff. Ff. Ff
Ff. Ff

Phenotype ratio: 2 for long fur and 2 for short fur


Conclusion:
Before I start please paraphrase this so you can get full credit.

For the first question it’s :

The dominant genotypes are FF & ff and the dominant phenotype is short hair.

For question 2: The genotype is ff and the phenotype for fur length is long hair

For question 3: the hamster could have the genotypes FF & Ff

For question 4: the hamster could have the genotype ff

For question 5:

Test One: yes, because all the hamsters had short hair

Test two: yes, because all except one had long hair

Test three: no, because not all of them had long hair, some had short hair.

For question six:

The Ff and the Ff are the mystery hamsters. The cross has shown that they can make offspring with short hair or long hair

Answer 2
Name and Title: your name, your instructor’s name, May 29, 2023, Heredity Lab Report

Objective(s): The purpose of this lab was to investigate how hamsters inherit traits from their parents.

Hypothesis:
Test One: If I breed a short fur, FF female with a short fur, Ff male, then I will expect to see short and some long fur offspring.
Test Two: If I breed a short fur, Ff female with a short fur, Ff male, then I will expect to see all short fur offspring.
Test Three: If I breed a long fur, ff female with a long fur, ff male, then I will expect to see all long fur offspring.

Procedure: The test variable (independent variable) is the fur length of the parents, and the outcome variable (dependent variable) is the fur length of the offspring.

Data:
Test One
Parent 1: FF
Parent 2: Ff
Phenotype ratio: 2:2 short fur: long fur

Test Two
Parent 1: Ff
Parent 2: Ff
Phenotype ratio: 4:0 short fur: long fur

Test Three
Parent 1: ff
Parent 2: ff
Phenotype ratio: 0:4 short fur: long fur

Conclusion: The results of the lab support the hypothesis that the fur length of the parents affects the fur length of the offspring. The data shows that when both parents have short fur, the offspring will have short fur. When one parent has long fur and the other has short fur, there is a 50/50 chance that the offspring will have long or short fur. When both parents have long fur, the offspring will have long fur.

Cyanobacteria, also known as blue-green algae, are a kind of bacteria found in many lakes. These organisms make their own food through photosynthesis. Small animals including mayfly larvae eat the cyanobacteria, and small fish such as yellow perch eat the larvae. The small fish provide food for larger fish, such as walleye.

Describe a model you could use to show the transfer of energy within the lake ecosystem. In your description of your model, make sure you include the position of each organism identified in the paragraph.

Answers

Girly I got you!

One possible model that could be used to show the transfer of energy within the lake ecosystem is a food web. A food web is a model that shows the flow of energy from one organism to another in an ecosystem.

In this food web, cyanobacteria would be at the bottom of the food chain, as they are producers that make their own food through photosynthesis. The mayfly larvae would be next in the food chain, as they eat the cyanobacteria. The small fish, such as yellow perch, would be at the next level of the food chain, as they eat the mayfly larvae. Finally, the larger fish, such as walleye, would be at the top of the food chain, as they eat the small fish.

The food web would be represented by a series of interconnected arrows, with each arrow pointing from the organism being eaten to the organism doing the eating. For example, an arrow would point from the cyanobacteria to the mayfly larvae, indicating that the larvae eat the cyanobacteria. Another arrow would point from the mayfly larvae to the small fish, indicating that the fish eat the larvae. And so on, until the top of the food chain is reached.

Overall, this model would show how energy is transferred from one organism to another in the lake ecosystem, with each organism occupying a specific position in the food chain.

Answer:

the transfer of energy in a lake ecosystem is a food web. In this model, the cyanobacteria are at the bottom and they are eaten by mayfly larvae. which is the larvae and then eaten by small fish like yellow perch, which are in turn eaten by larger fish such as walleye. The food web would be represented by arrows, showing the flow of energy from one organism to another. Each organism has a specific position in the food chain, with producers at the bottom and top predators at the top. This model demonstrates how energy is transferred through different levels .

Explanation:

Cyanobacteria, formerly known as blue-green algae, are photosynthetic microscopic organisms that are technically bacteria. They were originally called blue-green algae because dense growths often turn the water green, blue-green or brownish-green.

Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.

1. Matter cycles through this ecosystem as organisms consume each other and decompose. When organisms die, their bodies decompose, and the nutrients are released back into the soil. These nutrients are then taken up by plants, which are eaten by herbivores. The herbivores are then eaten by carnivores, which eventually die and decompose, releasing the nutrients back into the soil.

2. Energy moves around this ecosystem through a food chain. Producers (plants) use sunlight to produce energy through photosynthesis. This energy is then transferred to herbivores (rabbits), which are eaten by carnivores (hawks). Energy is lost at each level of the food chain through respiration and other metabolic processes, so the amount of energy available at each level decreases.

3. If a disease strikes the snake population, the population of hawks and rabbits would be affected. If the snake population declines, there would be fewer predators to prey on the rabbit population. This would cause the rabbit population to increase, which would lead to an increase in the hawk population as they have more food to eat. However, if the disease is severe and the snake population declines too much, there may be a shortage of food for the hawks, causing their population to decline as well.

4. If the rabbit population suddenly doubled, the effect on the grass would be negative. With more rabbits, there would be more grazing pressure on the grass, leading to overgrazing. Overgrazing can lead to a decrease in grass biomass, which can negatively affect other organisms that rely on grass for food and shelter. Additionally, with less grass available, the rabbit population may eventually decline due to a lack of food. This would cause a chain reaction that could lead to the decline of other organisms in the ecosystem.
I only know 7 and 8

7. So if a disease stroked the snacks population than the effect on hawks would be that they would feed off a different food source, such as the rabbit. The rabbits population would decrease and soon enough the hawk population would decrease because of the competition towards food. This happens because snakes are secondary consumers and hawks feed off both rabbits and the snakes to balance the populations. If one disappears or decreases than the hawks would aim toward the animal that has a bigger population, the rabbit. Making the rabbit population leading towards less food all around.

8. If the rabbit population doubled than the grass would decrease or would die. This would happen because there is to many consumers and the grass can not keep up with how much it is giving out. This would also lead to a decrease to the rabbit population making the population really low or back to normal, depends on how quickly the grass grows.

What is not a part of the immune system?

A Mucous membranes
B Liver
C Skin
D Saliva

Answers

Answer : B

Explanation:

The liver is not a part of the immune system. The liver is an organ that plays a crucial role in detoxifying the body, producing bile to help digest fats and storing nutrients. While the liver indirectly supports the immune system by removing toxins from the bloodstream, it is not a part of the immune system itself.

Answer:

B. liver

Explanation:

The immune system is a complex network of organs, tissues, cells, and molecules that work together to defend the body against harmful pathogens, such as bacteria, viruses, fungi, and parasites.

A Mucous membranes: Mucous membranes are part of the immune system as they serve as a physical barrier that helps to trap and prevent pathogens from entering the body. They are found in various areas of the body, including the respiratory tract, gastrointestinal tract, and urogenital tract, and are lined with special cells that produce mucus and immune cells that help fight against pathogens.

B Liver: The liver is not directly part of the immune system. It is primarily responsible for detoxification, metabolism of nutrients, and production of important proteins, such as clotting factors. However, the liver does play a role in the immune response by filtering blood and removing pathogens, toxins, and other harmful substances from circulation.

C Skin: The skin is the body's largest organ and serves as a physical barrier against pathogens, preventing them from entering the body. Additionally, the skin contains specialized immune cells that help defend against pathogens that may breach the skin's barrier, making it an important part of the immune system.

D Saliva: Saliva, which is produced by salivary glands in the mouth, contains enzymes that can help break down food and also has antimicrobial properties that can help inhibit the growth of bacteria and other pathogens in the mouth. While saliva has some immune properties, it is not considered a primary component of the immune system.

2.the primary consumers shown in the model are the rabbits , the secondary consumers are the snakes. Consumators are the ones that ead the producer/s.


thats all i can help with ( im so sorry ) but i hope u manage to get help for the rest!
For 3. Two living parts could be the grass and one of the other animals, while two non living parts would be Oxygen and the sun. Oxygen interacts with the animals and provides life, while the sun provides growth to the grass, and the grass provides food for the consumers. And a consumer like the snake, provides the continuous chain and food for the next consumer

4. The ultimate of energy is the Sun. It provides energy to the grass, which then starts the food chain. Without the sun food chain simply wouldn’t work, and it would die off quickly.
