A marine scientist measures the energy found in a system consisting of seagrass and sunlight. After the seagrass grows for one w

eek, the marine scientist concluded that radiant energy from the sunlight was transformed to chemical energy in the seagrass. Does this result validate or invalidate the Law of Conservation of Energy?
A=Validate, because energy cannot be created or destroyed but can change forms.
B= Invalidate, because energy should not enter an open system
C= Validate, because the overall energy in the seagrass is less
D= Invalidate, because this scenario describes an isolated system

Answer: A=Validate, because energy cannot be created or destroyed but can change forms.

Plants absorbs energy from sun, to prepare their food in the form of carbohydrates by photosynthesis.This chemical energy from food is required by the plants for cellular metabolism. The same process will occur in sea grass.

The law of conservation of energy, says that energy can neither be created nor be destroyed, but it can change it's form. In the given situation, the sunlight energy is converted into chemical energy in plants. Therefore, it can be said that radiant energy from the sun is conserved in the form of chemical energy in sea grass.

Therefore, the results of the experiment, is validate, because energy cannot be created or destroyed but can change forms.

Describe how the complete oxidation of 1 mole of glucose can generate 32 ATPs. You should include i) products of anaerobic glyco
inn [45]

Answer:

Explanation:

1.During glycolysis,four molecules of ATP are formed,and two are expended to cause the initial phosphorylation of glucose to get the process going.This gives a net gain of two molecules of ATP

For every glucose molecule that undergoes cellular respiration, the citric acid cycle is carried out twice; this is because glycolysis (the first stage of aerobic respiration) produces two pyruvate molecules per glucose molecule. During pyruvate oxidation (the second stage of aerobic respiration), each pyruvate molecule is converted into one molecule of acetyl-CoA—the input into the citric acid cycle. Therefore, for every glucose molecule, two acetyl-CoA molecules are produced. Each of the two acetyl-CoA molecules goes once through the citric acid cycle.

The citric acid cycle begins with the fusion of acetyl-CoA and oxaloacetate to form citric acid. For each acetyl-CoA molecule, the products of the citric acid cycle are two carbon dioxide molecules, three NADH molecules, one FADH2 molecule, and one GTP/ATP molecule. Therefore, for every glucose molecule (which generates two acetyl-CoA molecules), the citric acid cycle yields four carbon dioxide molecules, six NADH molecules, two FADH2 molecules, and two GTP/ATP molecules. The citric acid cycle also regenerates oxaloacetate, the molecule that starts the cycle.

While the ATP yield of the citric acid cycle is modest, the generation of coenzymes NADH and FADH2 is critical for ATP production in the final stage of cellular respiration, oxidative phosphorylation. These coenzymes act as electron carriers and donate their electrons to the electron transport chain, ultimately driving the production of most of the ATP produced by cellular respiration.

The answer is B categorical.

<span>One criticism of the DSM noted by your author is that it adheres to a categorical model, which means that a person is seen as either having a mental disorder, or not having a mental disorder. There is little or no allowance for “degrees” of a disorder.</span>

If cysteine is specified by the codons UGC and UGU, what are the anticodons present on tRNAs that carry cysteine?
MrRissso [65]

Answer:

AGC and ACA

Explanation:

Codons and anticodons are present in the form of triplets.Codons are present on the coding strand of DNA and on mRNA and their anticodon is present on transfer RNA.When codon present on mRNA binds to its anticodon on tRNA then appropriate amino acid is carried by tRNA on ribosomes for protein synthesis. For example, AGC and ACA anticodons are present on tRNA that binds to UGC and UGU on mRNA for amino acid cysteine.

Can anyone give a help with this please I have to submit it tomorrow!!
Usimov [2.4K]

Answer:

Q.1: I can't help you with this, sorry :(

Q.2: Seaweed is the producer because it takes energy from the water and sun in thermal reactions.

Q.3: Phytoplankton is the second-order consumer because they eat first-order consumers.

Q.4: Whelks and crabs because they eat limpets, which eat producers, and they also eat seaweed.

Q.5: Gulls are carnivores because they eat the crabs, and so are crabs because they eat mullets

Q.6: Limpets and lobster would become less populated, but not yet endangered. Gulls would starve and probably disappear from this ecosystem.

Q.7: Whelks' numbers would decrease because of the number of lobsters consuming them, but then lobsters would starve because of the decline in their food. Then this would repeat, shaking the whole ecosystem.
