Explanation:
Vestigiality is the retention during the process of evolution of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species.
which statement is true about natural selection?
Answer:
I would say B
Explanation:
Because atural selection is the mechanism for how evolution occurs over time. Basically, natural selection says that individuals within a population of a species that have favorable adaptations for their environment will live long enough to reproduce and pass down those desirable traits to their offspring.
Do you think seeds need water to start growing? Explain why or why not.
Yes, because the seed without water didn't grow at all. Create your own experiments to find the ideal amount of water for each kind of plant. Explain your findings below. More of anything is never better, because if you add too much water the plant can get drowned, in the process killing it[tex].[/tex]

-What is the advantage of a large population for rapid evolution?
-Do you think all species would be able to evolve adaptations to help them survive pollutants? Why or why not?

Answer:
-What types of toxins were found in the waters of the Lower Passaic Superfund site?
DDT and agent orange were found in the waters of the Lower Passaic Superfund site.
-How were some fish able to survive PCB levels thousands of times higher than sensitive fish can withstand?
in some tolerant fish, the trigger for the changes that can be caused by PCB levels are can be turned off which allows some fish to survive levels of PCB thousands of times higher than the levels affecting sensitive fish.
-What is the advantage of a large population for rapid evolution?
The advantage of rapid evolution is that the animals can survive and not get killed off.
-Do you think all species would be able to evolve adaptations to help them survive pollutants? Why or why not?
I don't think that all fish can get speedy evolutions like the killfish did because researchers think that they got a rare mutation which helped them survive. However as researchers say, in smaller populations with less diversity the chances that a rare mutation might happen is small.
-What will likely happen to these toxin-adapted fish if the waters are eventually cleaned up?
Once the water becomes clean, a tolerant fish with the mutation won't do as well as a sensitive fish would do.

lungs and capillaries both have porous linings that allow certain substances to move into or out of the structures. Which function do these porous linings most likely serve in living organisms?
A. heat release
B. gas exchange
C. carbohydrate absorption
D. osmotic pressure regulation
Answer:
B. Gas exchange
Explanation:
because the lungs bring air into your body, it needs a way to transfer the oxygen into your blood stream.
Luckily for us, our lungs have porous linings, which will help the oxygen go directly into our blood stream.
The porous structure of the blood capillaries and lung tissue allow the them to exchange gas
The porous structure of the lungs allow to exchange gas from the gas in the blood. Blood capillaries are tiny blood vessels in the body.
The gas in the blood was collected from the tissue from the body parts which is made possible because of the porous lining of the blood capillaries.
Therefore, the porous structure of the blood capillaries and lung tissue allow the them to exchange gas.

which structure in the figure would most likely be used to form muscles and connective tissue
Q3 because the muscle tissue isnt that complex and it inst that connective.Explanation:
Bone and muscles are the connective tissue. Muscle tissue is made up of sheets and fibers of muscle cells woven together.
What is connective tissue?Animals have a specific tissue called muscle that contracts when activated, applying forces to various body parts. Together, these fibers and sheets are referred to as muscles, which regulate many other contractile processes as well as an organism's movements.
Depending on their purpose, animals have one of three types of muscle. Despite modest differences, these muscles have a similar structure and function. Muscle tissue has a unified function and is frequently joined by the same nerve bundles.
Therefore, Bone and muscles are the connective tissue. Muscle tissue is made up of sheets and fibers of muscle cells woven together.

Our environment is sometimes divided into different spheres, including the geosphere, hydrosphere, cryosphere, atmosphere, and biosphere. Interactions between the geosphere and atmosphere can have an impact on Earth’s weather. Which of the following is an example of an interaction between the geosphere and atmosphere?
1.Melting of ice from a glacier into a body of water
2.Eruption of lava, gases, and ash from a volcano
3.Evaporation of water from the ocean
4.Animals completing cell respiration and exhaling CO2
Answer:
Eruption of lava, gases, and ash from a volcano
Explanation:
Volcanoes form most commonly in regions where one tectonic plate plunges beneath another tectonic plate. How does this process
lead to volcano formation?
OA. The plate plunging downward suddenly turns upward, breaking through the surface to form volcanoes.
OB. The plate plunging downward knocks loose part of the Earth's core, which rises up to form volcanoes at the surface.
OC. It causes strong earthquakes, which shake the ground upward into the shapes of volcanoes.
OD. It causes part of the overriding plate to melt into magma, which rises up to form volcanoes at the surface.
Answer:
OD is the correct answer
Answer:
The answer is
OD. It causes part of the overriding plate to melt into magma, which rises up to form volcanoes at the surface.
The role of the excretory system is to rid the body of toxic waste products. Which of these body systems also plays a direct role in removing waste products from the body?

A) brain.
B) kidneys.
C) skeleton.
D) skin.
1. The correct answer would be C) respiratory system.
Respiratory system is made up of set of organs which help in taking in oxygen and expelling out carbon dioxide from the body.
In humans, it is composed of nose, pharynx, larynx, trachea, bronchi, pair of lungs, and diaphragm.
Alveoli (in lungs) are the site of gaseous exchange where oxygen is exchange with carbon dioxide.
Carbon dioxide is the toxic waste product of cellular respiration. Circulatory system helps in transporting CO₂ from cells to the alveolar site where it is exchanged with oxygen and excreted out as a part of exhaled air.
