Answer:
The reaction catalyzed by an enzyme is very specific. Most enzymes are proteins with unique three-dimensional configurations based on their amino acid sequence. The specificity of an enzyme can be attributed to the compatibility between the shape of the enzyme's active site and the shape of the substrate.
Scenario A: Carmen reads an article in Tasty Food magazine stating that eating an apple can help you feel awake and alert. Scenario B: Yuki reads an article in the Professional Journal of Medicine stating that ginger root can help prevent some types of cancer. Which article is more likely to have been peer reviewed? How do you know?
Answer:
The article read by Yuki
Explanation:
The article read by Yuki is more likely to have been peer-reviewed out of the two articles illustrated in the scenarios.
This is because magazine articles are usually written by staff writers or freelance journalists as opposed to professionals that are responsible for writing professional journals. Moreover, magazine articles are intended for general public reading and as such, are written in general, non-technical languages while professional articles are written in technical languages intended for scholarly use.
Articles in magazines are usually unstructured and hardly report scientific results unlike those in professional journals that require well-structured formats.
Consequently, articles in the Professional Journal of Medicine read by Yuki is more likely to be peer-reviewed than the article read by Carmen in Tasty Food magazine.
Answer:
sample response:The article that Cicely read (Scenario B) has been peer reviewed. This article is published in a scientific journal and has been judged for quality by other professionals in the field.

Choose all the true statements about oxidative phosphorylation.
A. Oxidative phosphorylation occurs in the inner mitochondrial membrane.
B. The oxidation of NADH provides enough energy to produce three ATP molecules.
C. Oxidative phosphorylation is an anaerobic process.
D. The oxidation of FADH, provides enough energy to produce three ATP molecules.
E. Oxidative phosphorylation and the electron transport chain are called coupled reactions.
Answer:
A. Oxidative phosphorylation occurs in the inner mitochondrial membrane.
B. The oxidation of NADH provides enough energy to produce three ATP molecules.
Explanation:
Oxidative phosphorylation is the third step of cellular respiration, in which NADH2 or FADH electron carriers are oxidized to produce ATP. Oxidative phosphorylation occurs in the inner mitochondrial membrane. It is composed of two processes viz: electron transport chain and chemiosmosis.
Either NADH2 or FADH is used as the starting electron carrier. When NADH is used, its oxidation produces enough energy to generate 3 molecules of ATP per molecule while FADH generates 2 ATP molecules.

Ice fishermen drill holes in ice covered lakes so they can fish in the cold winter months. The water beneath the layer of ice remains
liquid. If the ice sank to the bottom, the lake would freeze from the bottom to the surface. This would freeze all of the lake's organism.
Which property of water explains this occurrence?
A lower pH makes the water more acidic, resulting in the neutral ice floating
The bonds, between the water atoms, break expanding the ice molecules so that liquid water can fill the spaces in between the frozen water
molecules
The hydrogen bonds of water expand during the freezing process, creating more volume and decreasing density of the ice.
The water's cohesive properties keeps the molecules close together, therefore, increasing the density ice.
Answer:
The hydrogen bonds of water expand during the freezing process, creating more volume and decreasing density of the ice.
Explanation:
Water has awesome properties that distinguishes it among all other substances, many of which is attributed to its hydrogen bonding. Liquid water contains hydrogen bonds that holds tightly its molecules. However, when this liquid water freezes, the hydrogen bonds between its molecules break and expands. This creates space for the water molecules to occupy as it turns to its solid form (ice).
This is the case of this ice-covered lake. The ice, when it sinks, causes the liquid water beneath to freeze because the hydrogen bonds between the water molecules are being expanded enabling the molecules to occupy more space (volume) and make it less dense than liquid water (decreased density).
Answer:The hydrogen bonds of water expand during the freezing process, creating more volume and decreasing density of the ice.

What is the best example of a cyclic event?
a. the appearance of Halley’s comet every 76 years
b. a hurricane moving up the east coast an hitting Long Island
c. an earthquake near Washington DC
d. a tsunami striking the east coast of Japan
The correct answer is A. The appearance of Halley’s comet every 76 years.
Explanation:
Cyclic events follow a pattern of occurrence, this means they occur every certain time and can be predicted. This category includes natural phenomena such as weather patterns or the phases of the moon. In this context, the one that is an example of a cyclic event is Halley's comet (option A) because the appearance of this comet occurs every certain time (76 years) and this can be predicted, which are two key features of cyclic events. Also, others such as hurricanes, tsunamis, or earthquakes do not follow a precise cycle or cannot be precisely predicted.

In what direction and with how much not force will the satellite move?
The net force is 0 N, so the satellite will not move.
The net force is to the right at 1500 N.
The net is to the left at 1000 N.
The net is to the left at 500 N.
Answer: D
Explanation:
The net force with which the satellite move is 500 Newtons and the satellite moves in the left direction. Thus, the correct option is D.
What is the net force?The net force on an object can be defined as the combined effect of the sum of all the forces such as pushing and pulling forces which are actually acting on the object. If all the forces which are pushing or pulling on an object are not balanced, then in this case a net force acts on that object which then makes the object to accelerate in the direction of the net force applied.
Net force = Sum of all the applied forces
Since, here the forces applied are in different directions.
Net force = 1000 N (towards left) - 500 N (towards right)
Net force = 500 N (towards left)
The net force has a magnitude of 500 Newtons and it is in the left direction because 1000 N is more than 500 N.
Therefore, the correct option is D.

How does leaf structure best represent the relationship between structure and function? It indicates the maximum height an organism can reach. It determines how a plant responds to changes in the length of the day. It can be used to determine the average lifespan of the plant. *It relates directly to the characteristics of the plant's environment*
Answer:
The correct answer is - *It relates directly to the characteristics of the plant's environment*
Explanation:
The relationship between structure and function can be represented by the leaf structure as the structure of a particular plant leaf gives an idea about the characteristics of the environment it is habituated.
In the dry area or deserted area, leaves are modified into spikes to save water in order to lower transpiration, number of waxy coating, number of chlorophyll, and other modifications that give an idea about the environment and light intensity, and other characteristics.
