Answer:
NASA studied astronaut twins Mark & Scott Kelly to determine the effects of staying in space for a year. ... Space presents unique stresses to the human body. With lower gravity levels, for example, bones and muscles are more likely to become weak since they no longer have to support the weight of the body.
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.
Explanation:
The ACTN3 gene encodes the alpha-actinin-3 protein which is present in fast-twitch muscle fibers.
What is ACTN3 protein?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.
The ACTN3 gene encodes the alpha-actinin-3 protein which is present in fast-twitch muscle fibers. These types of skeletal muscle are responsible for generating force at high velocity.
Individuals lacking the variant gene have the R/R genotype whereas those possessing the mutation can have either one (R/X genotype) or two (X/X genotype) copies of the variant gene. This variant form of the ACTN3 gene is very common in the general population.
Therefore, The ACTN3 gene encodes the alpha-actinin-3 protein which is present in fast-twitch muscle fibers.

Mutaulism
Commensalism
Parasitism
Competition
Predation
Answer:
Another reason is that Zebras and Antelope love the open African savannas – in comparison to Kudus or other antelopes that prefer the thicker bush. Being out in the open obviously makes these two antelope species very vulnerable – therefore they are teaming up and are best buddies.

Explanation:
In the United States, there has been an increase in the number of people infected by mosquito spread diseases that were previously found only in countries south of the United States. Scientists want to investigate the cause of the increase in mosquito spread diseases. Scientists have predicted that the mosquitos carrying disease have moved further north as global temperatures have increased.
Which questions would help investigate how the new mosquitoes are affecting the ecosystems of the United States? Select all that apply.
A. Have the natural predators to the mosquitoes also migrated north?
B. Are places in the United States using more pesticides to kill the new mosquitoes? If so, how are these pesticides impacting others in the ecosystems?
C. How have the food webs in the United States changed as a result of the new mosquitoes?
D. What types of organisms are preying on the mosquitoes in their new habitats?
E. How much money has been spent to fight the diseases caused by these mosquitoes across the globe?
Are places in the United States using more pesticides to kill the new mosquitoes? If so, how are these pesticides impacting others in the ecosystems?
Thus, An ecosystem is a region where different species of plants, animals, and other organisms coexist in harmony with the environment, including the climate and geography.
An ecosystem is a place where several types of living things coexist to create a bubble of life, including plants, animals, and other species. Ecosystems are made up of both biotic (or alive) and abiotic (or nonliving) components. Plants, animals, and other living things are considered biotic factors. Rocks, temperature, and humidity are examples of abiotic variables.
In an ecosystem, every component is dependent on every other component, either directly or indirectly.
Thus, Are places in the United States using more pesticides to kill the new mosquitoes? If so, how are these pesticides impacting others in the ecosystems?

1.) how are arthropods vital to fruit crops?
2.) how are earth worms important?
Answer:
1.) Arthropods are found in all consumers' roles of an ecosystem, whether they eat plants or animals, and some are important decomposers. They are important in the pollination of flowering plants. Some play an important role in soil aeration and water infiltration. They are vital to helping the soil be good so that the plants can grow and you can have delicious crops
2.) Earthworms eat soils and digest organic materials. Their excretion produces enriched soil that is critically important for plant growth.

Explain the following functions of a Lily Flower:
-Chloroplast
-Photosynthisis
-Seeds
-Roots
(Please only answer if you know what it is.)
I will give brainlest to the correct answer!
Answer:
Chloroplast.
Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells, including the synthesis of fatty acids, membrane lipids, ...
Phtosynyhsis.
The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process
Seeds.
Seeds serve several functions for the plants that produce them. Key among these functions are nourishment of the embryo, dispersal to a new location, and dormancy during unfavorable conditions.
Roots.
Root, in botany, that part of a vascular plant normally underground. Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.

3. What is a PRO of asexual reproduction?
4.What kind of organisms are corals? What adaptations do they have to help them eat?
5.Why are adaptations important for a species?
Answer:
1. Bears are highly intelligent, wide-ranging animals and can therefore suffer particularly badly in captivity. Many bears kept in zoos, circuses and road-side “shows” display abnormal behaviours, including repetitive pacing, swaying from side to side or bar-biting.
Bear Conservtion campaigns to end the confinement of bears for ‘entertainment’. We aim to address five main areas; circuses and shows, zoos and collections, bear farms, dancing bears, and bear baiting. Follow the links below to find out more. See also our separate section on Sanctuaries.

The Guam rail is a flightless bird found on the island of Guam. It builds a shallow nest on the ground and lays eggs throughout the year. There are no native species of snakes in Guam, so the Guam rail had no experience with snake predators until the brown tree snake was accidentally introduced sometime between 1944 and 1952. These snakes, which eat a wide variety of animal species, quickly established a large population on Guam.
How was the Guam rail most likely affected by the introduction of the brown tree snake?
A) The brown tree snake ate only species that lived in trees, so it had no effect on the Guam rail.
B) The Guam rail quickly developed the ability to fly in order to escape from the brown tree snake.
C) The population of the Guam rail declined, and the species nearly became extinct. D) The Guam rail began to build its nests in trees.
