Which of the following describes how humans can create a sustainable practice between the meat system and the green system?
Reducing the number of livestock to increase the number of crop farms
Using the waste and byproducts of livestock to help create more arable land for crops
Reducing the number of crops consumed by livestock by placing more animals in feedlots
Using the grass and seeds that are not consumed by livestock to feed nations with food scarcity
The option that describes how humans can create a sustainable system is : ( B ) Using the waste and byproducts of livestock to help create more arable land for crops
Ways to balance the meat and green systemTo balance the meat system and the green system, the systems should be interdependent on each other, that way excessive waste will be reduced and both systems will gain mutually. One way to achieve this collaboration is the use of waste products from livestock as manure to create more arable land which in turn will lead to better crop production.
Hence we can conclude that The option that describes how humans can create a sustainable system is Using the waste and byproducts of livestock to help create more arable land for crops.

Explain how considerations for human health help drive environmental policy decisions.
Answer:
Humans impact the environment, which can, in turn, have an effect on human health. Pollution is caused by human activity, and it also affects human health. Air pollution can cause respiratory problems and water pollution can lead to digestive problems. As human health is affected by these issues, concern increases and policies are enacted that address the causes of the issues. These policies do benefit the environment, but are, in part, brought about by concerns over human health.

What evidence partly supports the idea that the carbon in the cellulose of the tree is the same
carbon that was in the atmosphere before?
O The carbon combined with oxygen to make CO2.
O A chemical reaction occurred that converted sugar from within the tree into starch.
O The oxygen in the cellulose is the same oxygen that was in the air.
O A chemical reaction occurred in which the carbon in the atmosphere became part of a sugar molecule.
If the oxygen in the cellulose molecule found in a tree is the same oxygen that was found in the air, it can be used as evidence to support that the carbon in the cellulose is the same as the one in the atmosphere.
Carbon fixationCarbon, in the form of carbon dioxide, in the atmosphere is fixed into plant tissues as carbohydrates during the process of photosynthesis.
Oxygen is released during the process but the oxygen comes from the splitting of water.
Thus, if the oxygen found in the cellulose of a plant corresponds to the oxygen found in the atmosphere, it is an indication that the carbon in the cellulose is also the same carbon in the atmosphere.

least count is the minimum value you can measure with the specific device or it is smallest printed increment least count of smallest graduated cylinders is 25 ml.... to calculate least count of graduated cylinder you have to divide 100 by in the case of small graduated cylinder. to find L.C you have to divide mainWhat can happen to a protein when changes happen is the sequence of bases that make up a gene
Explanation:
A missense mutation is when the change of a single base pair causes the substitution of a different amino acid in the resulting protein. This amino acid substitution may have no effect, or it may render the protein nonfunctional.

Which is required for both anaerobic respiration and aerobic respiration?
oxygen
O water
O mitochondria
O glucose
Answer: Glucose
Explanation: Substrate is always required. Glucose is the substrate. Anaerobic respiration in absence of o2 and aerobic in presence of o2.
Aerobic respiration totally converts glucose into carbon dioxide and water, whereas anaerobic respiration only fully converts glucose into lactic acid or alcohol (alcohol fermentation) (lactic acid fermentation). Thus, option D is correct.
What similarity in anaerobic and aerobic respiration?The fact that glucose is used as the first molecule in both aerobic and anaerobic respiration is one of their similarities.
Additionally, both aerobic and anaerobic respiration result in the production of ATP, but aerobic respiration generates far more ATP than anaerobic respiration.
For a modest output of ATP, glucose is partially broken down in the cytosol during anaerobic respiration.
For a higher yield of ATP, aerobic respiration uses oxygen to completely break down glucose in the mitochondria.
Therefore, glucose is required for both anaerobic respiration and aerobic respiration.
