Energy and MatterDescribe the energy transformations that occur during photosynthesis and cellular respirationDescribe how energy is used in the body
The human body carries out its main functions by consuming food and turning it into usable energy. Immediate energy is supplied to the body in the form of adenosine triphosphate (ATP). Since ATP is the primary source of energy for every body function, other stored energy is used to replenish ATP
Cellular respiration needs oxygen and produces carbon dioxide, whereas photosynthesis consumes carbon dioxide and produces oxygen. Free oxygen is required for cellular respiration by us and most other organisms

Please HELP!!!?! Describe competitive and noncompetitive in inhibitors describe how mutations can lead to resistance with non-competitive inhibitors
The competitive inhibitor binds to the active site and inhibits substrate binding. The noncompetitive inhibitor binds to the enzyme at a different site. It does not prevent substrate binding, but it causes other changes in the enzyme that prevent it from efficiently catalyzing the reaction.
What is competitive inhibitor?Competitive inhibitor is defined as a chemical pathway is disrupted when one chemical substance inhibits the effect of another by competing for binding or bonding.
Noncompetitive inhibitor is defined as a type of enzyme inhibition in which the inhibitor reduces enzyme activity while binding equally well to the enzyme.
Thus, the competitive inhibitor binds to the active site and inhibits substrate binding. The noncompetitive inhibitor binds to the enzyme at a different site. It does not prevent substrate binding, but it causes other changes in the enzyme that prevent it from efficiently catalyzing the reaction.

How do you know the surface water is not there because the sediment is saturated?
The area below the water table is known as the saturated zone, and it is where all of the pore spaces between the sediment particles are filled with water.
Even in the lack of any silt or other sediment, depending on the kind of soil, the presence of surface water may still be a possibility.
On the stream bed, sediment particles are typically stationary and only move when the water is flowing swiftly enough to push them out of place. Typically, larger sediment particles weigh more, therefore the water must flow more quickly to be able to move the material.
Describe a sediment.Sediment is a term used to describe solid material that has been moved and deposited in a new location. Sediment contains rocks, minerals, as well as fragments of plants and animals. It might be as big as a boulder or as small as a single sand grain.

Question 2
Were the seeds in the "G" tube undergoing respiration? Use your results in Data Table 1 and Graph 1 to support your answer. Do your results
support your hypothesis?
Answer:
no
Explanation:
table and graph to validate the question!
Seeds are living organisms, and like all living organisms, they undergo cellular respiration to produce energy for their metabolic processes.
Cellular respiration is the process by which cells break down glucose and other organic molecules in the presence of oxygen to produce ATP (adenosine triphosphate), the energy currency of the cell. The equation for aerobic respiration in seeds is:
Glucose + Oxygen → Carbon dioxide + Water + ATP
During germination, seeds become metabolically active and start cellular respiration to provide the necessary energy for the seedling to grow and develop.
To determine if the seeds in the "G" tube were undergoing respiration, one would need to measure the consumption of oxygen and the release of carbon dioxide over time. If oxygen is being consumed and carbon dioxide is being produced, it indicates that respiration is taking place.
As for whether the results support the hypothesis, it depends on the specific hypothesis that was tested. If the hypothesis predicted that the seeds would undergo respiration during germination, and the data in Data Table 1 and Graph 1 showed oxygen consumption and carbon dioxide production, then the results would support the hypothesis.

Answer: The correct answer (the statement that does NOT apply) is A. Mesosarurus swam from one continent to the other in breeding pairs.
Explanation:
The remains of Mesosaurus (a freshwater crocodile-like reptile living between 286 and 258 million years ago) have been found in Southern Africa and Eastern South America. Scientists have proven that Mesosaurus was not capable of swimming between the continents, so the presence of their fossils on two continents has proven the theory of continental drift. There is additional evidence that supports continental drift, where the two continents were connected.

Describe two ways that each of the following pairs are similar with each other and two ways in which they differ from each other.a) facilitated diffusion vs. active transport
Solution:
Similarities:
1. Facilitated diffusion and active transport are two methods involved in the transport of molecules across the cell membrane.
2. In both facilitated diffusion and active transport, transmembrane proteins participate in the passage of molecules across the plasma membrane.
Differences:
1. The facilitated diffusion is the process when the diffusion of molecules across the plasma membrane occurs from a higher concentration to a lower concentration while active transport occurs against the concentration gradient.
2. The facilitated diffusion does not require energy to transport molecules across the membrane. while in the active transport energy is required to transport molecules across the membrane.
Why do some kinds of mutations cause greater changes in proteins than others? (Consider the different types of mutations and how they effect proteins made differentely)
Some types of mutations can cause greater changes in proteins because they result in a different amino acid being translated. This different amino acid provokes a different primary structure, a different active conformation and, in the end, a different biological activity. A certain type of point mutation (when a single base pair is altered), for example, can lead to this when it is a missense mutation. It can also lead to translate to a synonymous codon (coding for the same amino acid), but in this case it does not effect the protein and the mutation is called silent.
