How does high altitude affect breathing? please help
Answers
Per my research, it was said that the higher the elevation, the more difficult breathing becomes. The air at higher altitudes is colder, less dense, and contains fewer oxygen molecules, which means that you would need to take more breaths in order to get the same amount of oxygen as you would at lower altitudes.
Explanation:Hope this helped and please correct me if I am wrong. I did my research and I think this is right because of the elevation. Have a good one!

Answer:
The image shows an example of a(n) internal environmental factor affecting her fish's growth. Other conditions that could affect animal growth include genes and hormones.
Explanation:
tdlr- internal environmental factor, genes, hormones
The image shows an example of an external environment affecting her fish's growth. Other conditions that could affect animal growth include internal environment.
What is environment?An organism's or an ecological community's environment is the collection of physical, chemical, and biological variables that affect it and ultimately decide its form and survival.
Everything in our environment affects us. Whether they are living or not is up to you. It consists of natural forces such as chemical and physical ones.
Environments are where living things exist. They are continually interacting with it and modifying their behavior to fit the circumstances.
Clean air and water, rich land for growing food, as well as energy and material inputs for production, are all provided by good natural surroundings.
The picture demonstrates how an outside environment can effect a fish's growth. Internal environment is another factor that might influence an animal's growth.
Thus, this can be the complete scenario for the gold fish.

Which would be an internal structure of this organism for a typical plant?
1. leaf
2. root

Answers
Answer:
A Root
Explanation:
Plants have a root system, a stem or trunk, branches, leaves, and reproductive structures (sometimes flowers, sometimes cones or spores, and so on). Most plants are vascular, which means they have a system of tubules inside them that carry nutrients around the plant.
Roots anchor the plants in the soil and absorb nutrients and water that are needed by the rest of the plant.

Byron goes rafting on the Colorado River. As he paddles along, he can see the erosion, weathering, and deposition caused by the river. Explain how a river is responsible for causing erosion, weathering, and deposition. Give an example of each.
P.s. no links or you will be reported
Answers
Answer:
Erosion by a river is caused by its capacity to curve out rocks and carry soil particles as sediments due to its erosion power. Rivers carve out rocks to form the pebbles you see in a river and also the rapids and cataracts.
A river contributes to the weathering of rocks such as limestone rocks. The water dissolves the calcium carbonate minerals in the limestone rocks making it brittle and easily crumble. Water also causes ferrous rocks to easily crumble due to turning of the iron minerals into rust.
rivers deposit their sediments when their velocity decreases. Deposits by rivers cause features like oxbow lakes and deltas that are observed at the mouth of rivers, where the slope gradient is very low.

What do you mean by predators?A predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation and parasitoidism.
Predation involves four steps: search, recognition, capture, and handling. The possibility of co-evolution of predator and prey operates at each of these steps. Predators search the environment for acceptable prey.

Help me please
Answers
Hope this helps !!!
The primary mode of reproduction that separates flowering plants from non-flowering plants. While non-flowering plants need on dispersion to continue their life cycle, flowering plants depend on pollination for reproduction.
What is flowering plants and non-flowering plants?Seeds that are protected by a flower or fruit are used by flowering plants to reproduce.
Conifers, ferns, and mosses are examples of non-flowering plants. Conifers produce seeds in cones to reproduce. Spores are used in fern and moss reproduction.
The reproductive organs of plants, called flowers, transport both male and female gametes.
These flowers bear fruits once fertilised. Non-flowering plants are ones that reproduce by spores but don't produce flowers.
Plants differ in appearance, but they always share three characteristics: they are multicellular; they can produce their own food; and they are green.
Thus, these are some similarities between the major stages in the life cycles of flowering plants and non-flowering, seed-bearing plants.
