After Frida stops exercising, she continues to breathe heavily. What is most likely occurring in her body?
Answer:
Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration
Explanation: Anaerobic cellular respiration occurs and due to the lack of oxygen she takes deeper breaths. That way, there's oxygen in the muscles while respiration occurs.
Answer:
Frida is lacking air, or oxygen, because of her exercising. She starts panting quickly to take in air faster and make up for the oxygen loss. The heart beats hard during exercise, and needs oxygen to return to a normal pace
Using what you have learned in the lesson and gathered from your survey, write a conclusion paragraph analyzing your results in your conclusion. Be sure to address the following questions:
- Identify the trait that you believe to be dominant for each of the features surveyed. Explain your reasoning.
- It is possible that a recessive trait in a survey such as this one may have a greater total number than its dominant counterpart. Explain how that might happen in an investigation like this.
- How might surveying a different number of people or different population of people possibly change the percentages you calculated?
My data tables are in the picture.
Answer:
A trait that is going to be dominate is the No Cleft because it is the most produced data.
Surveying different people like your friends will add data that could be random, unlike just doing a data analysis on your family where the results will be similar, adding outside data will "Spice things up" and make it interesting.
I can help you out with some but I can not just do your homework for you, this looks like a whole lab assignment, If you get confused let me know and I can help you with the rest but I can't do it all for you.
Explanation:
Answer:
In conclusion, my family dominant traits are curly hair, free earlobes and normal chins. My nana had 6 kids with the same man so im that's the reasoning for us all having similar features. I see that my grandpa has had a receding hairline his whole life. Two of his sons display the same receding hairline. My mother has hair on her fingers but my dad doesn't, I have a small amount on one of my fingers. I have a free ear just like my dad. My mom's side is all sicilian and my dad is from the caribbean islands. so i have a mixture of my moms wavy hair and my dad's frizzy coils, creating a kinky coily curl mixture. i'm not surprised 70% of us have some type of dark curl or wave. For it to be possible for a person to show a recessive trait that neither parent has. That person has to have two recessive alleles responsible for the trait. One recessive allele is from a mother and another is from a father. So, my parents have to be heterozygous in order to pass on recessive alleles to the offspring. Only thing that surprised me was the attached ears. If parents have recessive traits then those traits will probably have higher numbers compared to the dominant counterpart. Serving a different group of people and a different number would absolutely change the percentages because it’s a bigger amount of people so there’s going to be more variety. And if we did investigation on a group of all different types of ethnicities we would absolutely have a different percentage.

The source of energy shown in the image is ____. (renewable, nonrenewable, polluting) A drawback of building a dam is that _____. (It will destroy ecosystems, it requires fossil fuels, it won’t be useful for irrigation)
Answer:
The source of energy shown in the image is RENEWABLE. A drawback of building a dam is that it will DESTROY ECOSYSTEMS.
Explanation:
A drawback of building a dam is that it will destroy ecosystems (option A), and the water is also a renewable source as building a dam involves altering the flow of a river.
What is a dam?Building a dam can have a variety of impacts on the natural environment, some of which can be negative. One of the most significant impacts is that the construction of a dam can destroy ecosystems. Rivers and their associated ecosystems are dynamic systems that are adapted to the natural flow of water, sediment, and nutrients. When a dam is built, it changes the flow regime of the river, which can lead to the loss of wetlands, the alteration of the river's course, and the degradation of downstream habitats.
Hence, the drawback of building a dam is that it will destroy ecosystems (option A), and the water is also a -renewable source as building a dam involves altering the flow of a river.

State one effect the reintroduction of the wolf may have on the coyote population within the Adirondacks
effect. Explain why it would have this
Answer:
Decrease in the population of coyote occurs after the reintroduction of the wolf within the Adirondacks effect.
Explanation:
Wolves are the top predator in the ecosystem. They hate coyote and kill them and sometime eat them too. So the reintroduction of the wolf decreases the population of coyote by killing them directly and by consuming the prey and the coyote die due to hunger. Coyote feed on rabbit, snakes, deer, fruits and grasses so decrease in coyote population increases the availability of grasses and other animals for different animals.

What are the similarities between recessive and dominant alleles
- they are both found in the same place
- they are both passed down to newer generations
- both of them can determine your traits
Answer:
they are both found in the same place
they are both passed down to newer generations
both of them can determine your traits
Explanation:
When an allele is dominant, the characteristic it is connected to will be expressed in an individual. When an allele is recessive, the characteristic it is connected to is less likely to be expressed. Recessive traits only manifest when both alleles are recessive in an individual.
Which describes vestigial structures and how they relate to evolution?
Snakes have tiny internal hind leg bones, indicating that they likely descended from lizards.
Humans and dogs have similar bone structures in their forelimbs, indicating a common ancestor
Dolphins and birds have structures that are adapted for swimming, but the structures did not evolve the same way.
The DNA of mice and chickens shows similar patterns, suggesting that the two species are related
Answer:
The correct answer is - Snakes have tiny internal hind leg bones, indicating that they likely descended from lizards.
Explanation:
Minimal structures are the structures in a life form which are not, at this point being used. In past these minimal structures played out some significant capacities in those life forms however bit by bit because of development now they have become non utilitarian in their body.
Reptiles and snakes both are reptiles yet reptiles have a practical rear appendage which causes them in slithering, snakes have been developed from reptiles however so as to move they creep instead of creeping so their rear appendage doesn't serve any capacity in development. Rear appendages are available in their body as a minimal organ.
Thus, The correct answer is - Snakes have tiny internal hind leg bones, indicating that they likely descended from lizards.
Answer: Snakes have tiny internal hind leg bones, indicating that they likely descended from lizards.
