Yall Im struggling, if u cant read it, the question is “why does a mountain climber need an oxygen supply at very high altitudes, even tho the air still contains 21% oxygen?
Answers
Answer: Because it is harder to draw breath in. And the cold
Explanation: At higher altitudes, it becomes more dangerous, and you can develop altitude-related illnesses such as HAPE and HACE. I read a book called Into Thin Air, and in the book the author goes into detail on the details/complications of climbing Mt.Everest and oxygen needs. Mountain climbers use canisters of oxygen called Supplemental Oxygen.

would you expect a plant to produce more oxygen on a cloudy day or a sunny day? explain
Answers
Answer:
You would expect a plant to produce more oxygen on a sunny day because there are more sun rays available to plants so photosynthesis is easier to maintain, as well as oxygen production.

2. Which atom in the water molecule is negatively charged?
Answers
Answer:
oxygen atom
Explanation:
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
Answer:
The oxygen
Hydrogen is positive

Sound waves travel better through solid than through a gas. Explain why this is true.
Answers
Answer:
solids are more tightly packed together (the molecules) than liquid or gas so it allows it to travel through vetter/faster
Answer:
Explanation: Solids are packed together tighter than liquids and gases, hence sound travels fastest in solids. The distances in liquids are shorter than in gases, but longer than in solids. Gases are the slowest because they are the least dense: the molecules in gases are very far apart, compared with solids and liquids

DNA carries the information needed to make proteins. How is this information used to make proteins?
Answers
Answer:
The information contained in DNA is expressed giving rise to proteins, through transcription processes, a step by which the information is transferred to a messenger RNA molecule (m-RNA) and, through the process of translation, the message carried by m-RNA is translated into protein.
Answer:
DNA is transcribed into mRNA. Ribosomes "read" the mRNA and translate each group of three nucleotides into amino acids to build proteins, with the help of tRNA.

Find 2 ways that natural gas forms. List the steps of the two carbon pathways below. Label each location with A for atmosphere, B for the biosphere, G for geosphere, or H for hydrosphere. Use P for the anthroposphere.
Answers
Answer:
Biogenic and thermogenic
Explanation:
Biogenic and thermogenic are the two ways or mechanism that is responsible for formation of natural gas. Biogenic gas is formed with the help of methanogenic organisms that is present in marshes, bogs, landfills, and shallow sediments. Thermogenic gas is formed from organic matter that is buried in the deeper earth where the temperature and pressure are very high.
The organic pathway of the carbon cycle is the pathway in which carbon moves from atmosphere, through producers, herbivores and other organisms in the ecosystems, and converted back to the atmosphere.
In geological pathway, carbon moves from the atmosphere, through the ocean to rocks and the mantle, and then back to the atmosphere.

What is the difference between flu viruses and the measles virus?
Answers
Answer:Influenza and measles are viruses that both cause respiratory symptoms. The typical measles rash does not appear for 2-4 days, so during influenza season, symptoms of early measles can be confused with influenza.
Explanation:
Explanation:
Vaccines for both measles and flu already exist, however the flu vaccine must be updated because of the virus's ability to change and adapt in order to invade cells in the human body. The goal of researchers was to find genes in each virus that cannot survive changes.
By comparing two similar viruses which attack the body in similar ways through the lungs, researchers confirmed that the measles virus is much less open to evolutionary change by using an experimental technique called insertional mutagenesis to change the genes of each virus.

Answers
Answer:
Top to bottom: 5, 3, 2, 4, 1
Explanation:
I'll take a shot! Here I go!
5 (Sun) = top; we get all our energy from the sun
Then 3 (plants); plants can convert sunlight into food for themselves via photosynthesis
Then 2; we're talking about herbivores that eat plants, right?
Then 4; these are probably~ carnivores
Then 1; when a living thing dies, these guys consume the corpse and return the energy to the ecosystem
Have a great day!
Answer:
Sun
Primary Producers
Primary Consumers
Secondary Consumers
Decomposers
Explanation:
Energy coming from the sun is converted into chemical energy (or glucose) by plants. Primary consumers (herbivores) eat those plants and gain the energy they produced. Secondary consumers (carnivores probably) eat the primary consumers and gain that energy. Then they die and decomposers (fungi) return their energy into the soil.
