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

In some parts of Hawaii, non-native grasses have been planted for cattle feed, replacing come of the native rain forest plants. Which statement describes the MOST LIKELY impact of the replacement of rain forest plants with nonnative grasses?
a
The biodiversity of these areas will decrease.
b
Rainforest plants will outcompete nonnative grasses for resources.
c
Less nitrogen will be absorbed from the atmosphere over these areas.
d
Cattle will get fewer nutrients grazing on nonnative grasses than on rain forest plants.
Answer:
It should be
A. The biodiversity of these areas will decrease.
The biodiversity of these areas will decrease describes the MOST LIKELY impact of the replacement of rain forest plants with nonnative grasses. thus option A is correct.
What is biodiversity ?
Biodiversity can be defined as the total number of living organisms present in a particular area dependent upon different factors like habitat, competition among species, resources, and climatic conditions.
There are three types of biodiversity such as genetic, species, and ecosystem diversity.
In a specific area the increase in human population makes a problem for the biodiversity with the increase in population and it comes a need to convert natural habitats to land for human consumption and shelter.

Explain why a food web is a more realistic model of energy flow than a food chain.
No links or jibberish!
Answer:Las redes tróficas consisten de varias cadenas alimentarias interconectadas y son una representación más realista de las relaciones de consumo en los ecosistemas. La transferencia de energía entre niveles tróficos es ineficiente, con una eficiencia típica de alrededor del 10%.
Explanation:
Answer:
Food chains only show one path by which energy can move through an ecosystem. Because most organisms eat a variety of things, they are part of many food chains. A food web shows the interconnected food chains in an ecosystem and the multiple paths through which energy can move, which is why it is a more realistic model for showing energy flow.

Please write 1–2 sentences relating the water cycle and wind to temperature and precipitation.
Quickly please
Answer:
Some examples of precipitation include rain, snow and hail. Precipitation is a part of the water cycle. Once the rain leaves the clouds, it forms a stream/ river to get to a lake or ocean. From there transpiration takes place to make those droplets form clouds. The sun mover the clouds, and we get back to transpiration.

Geological activities have distributed Earth’s resources, including energy resources, unequally around the world. What is the original source of energy on Earth?
Answer:
Energy from the sun. Solar energy is the original source of most energy on Earth
what do we mean when we sat technology helps “ redistribute" natural resources?
Technology is an important factor that an change substances into resources. ... It is their ideas, knowledge, inventions and discoveries that lead to the creation of more resources. Each discovery or invention leads to many others
In addition, technological advances are helping to bring down the cost of renewable energies
Explanation:
Resource distribution refers to the distribution of resources, including land, water, minerals, wealth in general among corresponding geographic entities (states, countries, etc.). Resource distribution refers to the geographic occurrence of resources on earth. In other words, where resources are located.
What is the origin of the energy that all organisms need to carry out life functions?
A. food
B. producers
C. plants
D. the Sun
Answer:
D. The Sun
Explanation:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. This process begins the flow of energy through almost all food webs. Food is sunshine stored in chemical form. Organisms use the stored energy in food to fuel all living processes.
Define each of the stress types:
a. Stress

“Coronavirus Is Mutating”, what could be the reason for it? (Research) and tell your answer in your own simple words
Answer:
Explanation:
Coronavirus is mutating because as more people are getting the virus, that gives that virus a change to mutate and form a different strand. When a virus hijacks a person cells, it causes that cell to start producing the DNA of the virus, but because human cells where not made to produce the DNA of a virus, mistakes happen, thus slightly changing the DNA of the virus which can then cause a new strand of the virus to appear.

Answer:
The Sun
Explanation:
The sun has the greatest gravity because it exerts a lot of gravity, or pull, on the planets—enough to make them orbit around it. Also, the Sun's gravity is about 27.9 times that of Earth, and the gravity of the moon is less than Earth's.

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.
