Discuss the similarities and differences between whale flippers and flukes and fish fins, using the scientific terms "homologous structures" and "analogous structures" in the discussion.
Answer:
The whale's flipper and tail flukes and fish fins are analogous structure as they have different structural formation but they perform the same function. Flipper and tails are locomotory organs in the whale and helps the whale in propelling similarly fins in the fish assist the fish in swimming.

Which of the following statements about animal behavior is false?
A. Two animals of the same species will behave differently.
B. Instinctive behaviors begin at birth.
C. Learned behaviors are demonstrated to young animals by adult animals.
D. Animals behave in ways that enhance their chances of survival.
Answer:
i feel like is D not sure tho im sorry if im wrong
The following statements about animal behavior are false: Two animals of the same species will behave differently, as shown in Option A, as there are many similarities in behavior between members of the same species.
What is animal behavior?Animal behavior is a complex and fascinating topic that can shed light on a variety of biological questions, including how animals interact with their environment, how they communicate with each other, and how they adapt to changing conditions. One important aspect of animal behavior is the distinction between instinctive and learned behaviors. Instinctive behaviors are innate, meaning that they are genetically programmed into an animal and do not require any prior learning or experience.
Hence, the following statements about animal behavior are false: Two animals of the same species will behave differently, as shown in Option A.

Explanation:
The test: To understand if the ACTN3 protein affects running ability, researchers conducted a test. They recruited a group of competitive runners and measured the level of ACTN3 protein molecules each runner had in their bodies. Then, they had the runners participate in a sprint (a short-distance run). During the test, the runners sprinted as fast as they could for 100 meters.
Evidence: Scientists found that the runners who sprinted the fastest had the highest amount of ACTN3 protein molecules in their bodies.
Do you think that this evidence shows that the ACTN3 protein determines running ability? Explain your ideas using the words protein, trait, and feature in your response.
Answer:
The ACTN3 gene encodes the alpha-actinin-3 protein which is present in fast-twitch muscle fibers. ... Although having one or two variant forms of the ACTN3 gene does not have any harmful effect, an individual's ACTN3 genotype does affect their athletic ability.
hope that helped

Think about the climate that you live in. How does your climate relate to the air and ocean currents?
Answer: Ocean currents can affect the climate of nearby land. Cold ocean currents make nearby land colder and warm ocean currents make nearby land warmer. Places near the ocean experience moderate temperatures year round due to the fact that water has a high specific heat, meaning that it cools and warms slowly. Places further inland have a higher temperature difference between seasons because land has a low specific heat which means that it cools and warms quickly. Ocean currents influence rainfall patterns. Warm, moist air associated with warm ocean currents increase precipitation.
bye im too lazy for this
Answer:
If you are closer to a ocean current, you can experience moderate temperatures year round because the water has a specific temperature. his would make the land near the ocean take longer to heat up and cool down. Ocean currents affect the climate of the land near it. They move warm and cold water currents around the globe. Cold ocean currents make nearby land colder and warm ocean currents make nearby land warmer. Places further from the coast have a higher temperature difference between seasons because land has a low specific heat which means that it cools and warms quickly. Of course weather you are closer or further also changes things. If you are closer to the equator you have higher temperatures, and the further away you get, the colder it gets. Ocean currents also influence rainfall patterns. Perspiration normally happens near the ocean, so the air will be humid and moist due to the water in the air going up to make clouds. If you are near a warm air current, you will get more warm ail on top of that. However, if you are closer to a cold air current it will be colder. If you are close to both, you are likely to experience tornadoes and hurricanes due to the warm and cold air currents coming together.

Label the angle of incidence and the angle of reflection in the Figure below.
In the picture, I have highlighted the angle of incidence blue and the angle of reflection red.
hope this helps :)
Angle of incidence refers to the angle between the incident ray and the normal, while angle of reflection represents the angle between the reflected ray and the normal.
Thus, angle of incidence is the angle formed by the incident ray which is the light beam flowing in and the normal which is a line perpendicular to the surface at the point of incidence. The angle of reflection, denoted by the symbol r, is the angle between the normal and the reflected ray of light (the ray of light that bounces off the surface).
The angle of incidence and angle of reflection are equal, according to the law of reflection. The angle at which light reaches a surface and the angle at which it reflects off of it are identical. This fundamental concept describes how light interacts with surfaces, such as mirrors or smooth objects.

Explain the flow of energy from the sun to sunflower and then on to a cardinal that ate the sunflower seeds. How did the energy help all three of these organisms to stay alive?
Answer:
The energy from the sun moved in the form of Light radiation, which the Sunflower then used in a process called photosynthesis. They use this to make sugar and that's what grows the seeds. This is then eaten by the cardinal, who uses it as chemical energy to fuel itself. The flower is growing from the energy that the sun gave off, and the cardinal recieves energy from the seeds.

Answer:
It includes more organisms in the ecosystem that would otherwise not be shown in a food chain.
Explanation: Food chains show just a single feeding pattern. Each organism has a single role in the ecosystem. Food chains make it easier to visualize trophic levels, or how energy moves through the ecosystem. This is why webs are considered to be more realistic than simple food chains.
