Write a sentence that compares the reactants and products of photosynthesis with the reactants and products of respiration.
Answer/Explanation:
Using solar energy, photosynthesis uses carbon dioxide and water to produce glucose and oxygen, whereas respiration uses glucose and oxygen to produce energy, releasing carbon dioxide and water.
Therefore, photosynthesis and respiration act as a cycle, using reverse reactants and products.
Photosynthesis builds food for the cell to use, respiration uses this food to power cellular processes.
A cell is considered cancerous when it acquires a mutation that makes it unable to regulate its cell cycle, and as a result divides more often than a normal, healthy cell.

The divisions of the autonomic nervous system are distinctly organized. How is the sympathetic division arranged?
Answer:
This question is incomplete
Explanation:
This question appear incomplete because of the absence of options. However, the sympthetic nervous system is one of the two main distinct divisions of the autonomic nervous system. The sympathetic nervous system is also distinctly organized with two classes of neurons; some have there soma (cell bodies) within the spinal cord while some have there soma outside of the central nervous system in the ganglia.
Neurons are specialized cells responsible for transmitting information to some nerve cells, muscle cell and/or gland cells.
An organism has three different versions of Gene Tyx- version a, b, and c. Determine the inheritance pattern of this trait. Then list below all of the different genotypes that an organism with this gene could have
Answer:
The inheritance pattern of these traits will be independent. However, it will depend on the factor that which trait is dominant or recessive. It might also show incomplete dominance.
The different genotypes that organisms of this population might have are aa, ab, ac, bb, bc , cc. If neither of the alleles are completely dominant over the other, then incomplete dominance might exist for such genes.

Describe the famous experiment related to gravity that Galileo may have performed. Include the results. Also, state whether the results support the law of gravity. Explain your answer.
Answer:
Galileo performed a famous experiment where he used a ball rolling on a ramp (inclined plane) to study the motion of objects under the influence of gravity. The ramp allowed him to make more precise measurements because the ball moved more slowly along the ramp than if it were simply dropped. Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle's theory of gravity (which states that objects fall at speed proportional to their mass). Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. Newton took this as his first law of motion. One result of the experiment surprised Galileo, and one surprises us. Galileo found that the heavy ball hit the ground first, but only by a little bit. Except for a small difference caused by air resistance, both balls reached nearly the same speed. And that surprised him. According to history, Galileo’s experiment on falling bodies largely contributed to Isaac Newton’s Law of Gravity. In Galileo’s experiment, he is said to have dropped balls from the Leaning Tower of Pisa. The balls were made of the same material but had different masses. Galileo set out to prove that the time it took for these objects to reach the ground would be the same. Galileo proved that objects reached the ground at the same time.

What statement best explains why repeated trials are an important part of science?
A) By repeating trials of an experiment, you can make sure your results are more accurate.
B) It is more likely you will get the result you expect if you perform repeated trials.
C) The more times you repeat a trial, the less likely you'll identify a source of error.
D) Trials in an experiment increase the chances that you will make a mistake.
Answer:
I think it is A because it seems more logical to do more trials for a accurate answer
Answer:
A
Explanation:
By repeating trials, you can get the highest and lowest values of the same experiment and in the end get an average result.
This is why when titrating we perform the experiment two to four times, then find the average. That average is the median and therefore the most likely result of the experiment.
Which of the following is not a reason we become shorter as we age?
As a person ages, vertebral bodies lose bone mass (osteoporosis) resulting in smaller vertebrae that stack closer together.
As a person ages, the ligaments connecting vertebrae together are weakened, resulting in a more pronounced kyphosis. This posterior curvature of
the spine lowers the skull, making you shorter.
As a person ages, the intervertebral discs become thinner and the vertebrae will be stacked closer together, resulting in shorter stature.

Incorrect: Try Again: 4 attempts remaining
Answer:
The correct answer is - As a person ages, scoliosis may develop resulting in an abnormal spinal curvature and shorter stature.
Explanation:
Scoliosis is a condition in which spine curvature towards the sides takes place before the puberty during growth period or spurt normally. The cause of this condition could be muscle dystrophy or palsy and similar condition.
This affects the stature of an individual but not affected by age as it remains constant normally after development or growth till puberty. All other conditions are associated with the short stature and influenced by the age.

The manner in which several different ions and molecules move through a cell membrane is shown in the diagram above. For each lon or molecule, the relative concentration on each side of the
membrane is indicated. Which of the following accurately describes one of the movements taking place?
A
Glucose is transported into the cell by active transport
Subm
B
Nat is transported into the cell by active transport
с
The movement of glucose through the membrane requires ATP hydrolysis
D
Na transport out of the cell requires ATP hydrolysis
Answer:
The correct answer is - D . Na transport out of the cell requires ATP hydrolysis
Explanation:
Sodium-ion moves or transported from the inside of the cell to the outside the cell by the process called active transport. Active transport takes place takes place when the movement is against the concentration gradient to a higher concentration area through the cell membrane.
Active transport requires energy in order to transport the molecules or ions from low concentration to high concentration. In sodium-potassium pump get the energy from the hydrolysis of the ATP.
The given diagram represents the transport of sodium out of the cell using active transport. Active transport utilises the energy or ATP released during respiration. The correct answer is that sodium is transported out of the cell requires ATP.
Active transport is defined as the transport in which molecules move from lower to higher concentration, against the concentration gradient. The active transport requires the hydrolysis of energy to move across the cell. The sodium-potassium pump follows the active transport, such that:
The pumping of ions against the concentration gradient requires the addition of energy. The high-energy molecule is used to facilitate the active transport of sodium ions during the sodium-potassium pump.Therefore, the image represents the sodium is transported out of the cell by active transport.

Suppose you do this test on a hypothetical Staphylococcus species with the antibiotics penicillin (P-10) and levoflaxacin (L-5). You record identical zone diameters of 25 mm for the levoflaxacin and penicillin disks. Which antibiotic would be more effective against this organism? What does this tell you about comparing zone diameters to each other and the importance of the zone diameter interpretive chart?
Answer:
Levoflaxacin
Explanation:
Levoflaxacin is the antibiotic which is more effective than penicillin against Staphylococcus species because Staphylococcus species are more resistance to penicillin while not resistance against levoflaxacin antibiotic, so the Levoflaxacin is more effective against Staphylococcus species of bacteria. Levoflaxacin kills about 99.9% of Staphylococcus species so we can say that it is more effective than penicillin.
The most effective antibiotic would be Levoflaxacin and this would be seen by comparing the diameter zones, which shows why the interpretation of these zones is so beneficial.
We can arrive at this answer because:
Staphylococcus is a genus of bacteria that has been resistant to penicillin since the time penicillin was discovered.In this case, when applying penicillin to a Staphylococcus culture, the bacterium can reproduce and form large zones in diameter.Staphylococcus is not resistant to Levoflaxacin and therefore it will form discs with small diameters because it will not be able to reproduce efficiently.In this case, we can state that the analysis and interpretation of the diameter zones are very important to determine the resistance of bacteria to different types of antibiotics.

An individual inherits two defective copies of the MLH1 gene, a protein involved in mismatch repair of DNA during its replication. What do you predict will be the consequence of deficient mismatch repair upon DNA replication?
Answer:
New mutations will become permanent
Explanation:
Human MutL homolog 1 (MLH1) gene is a well-known tumor suppressor gene that encodes for a DNA mismatch repair protein. The MLH1 protein is part of the DNA mismatch repair (MMR) genetic system which recognizes and repairs the incorrect addition of nucleotides during DNA replication and recombination. It has been shown that inherited mutations in one allele of the MLH1 gene increase the risk of cancer, especially colorectal cancer.

How does the introduction of invasive species such as the brown tree snake upset the stability of the legal system
Answer:
Invasive species compete for the same natural resources such as food and water which the native species also need for survival.
Explanation:
Invasive species upset the stability of the ecosystem because the prey in their new environment does not have the needed defense against them. They also upset the food chain, consume so much, and overpopulate in the new territory thus causing the extinction of the native species.
The introduction of brown tree snakes in Guam disrupted the ecological system as their population increased rapidly because their preys in this new environment lacked the ability to defend themselves against the brown tree snakes. For this reason, more than twelve native birds in the Guam Islands went into extinction. They also consumed the natural resources needed for the survival of the native species.

Autotrophs, such as plants, use light to make their own food. What happens to the light absorbed by a plant during photosynthesis?
Answer:
When light energy reaches the pigment molecules, it energizes the electrons within them, and these electrons are shunted to an electron transport chain in the thylakoid membrane.
Explanation:
During photosynthesis, light absorbed by plant is used for energizing electrons for an electron transport chain to take place in thylakoid membrane.
What is photosynthesis?Photosynthesis is defined as the process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in the form of molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the percent of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and have a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles which are called chloroplasts while in bacteria they are present in plasma membrane.

Which is a metamorphic process?
A. Lithification
B. Melting
C. Meteorite impact
D. Weathering
Melting is a metamorphic process. Thus, the correct option is C.
What is metamorphism?Increases in temperature, pressure, and chemically active fluids forms metamorphism, which transforms existent rocks into new forms. Igneous, sedimentary, and other metamorphic rocks may be affected by metamorphism.
Movements in the earth's crust pull the rock down, and it gets hotter and hotter as it goes deeper. A rock melts at temperatures between 600 and 1,300 degrees Celsius (1,200 and 2,400 degrees Fahrenheit), transforming it into magma (molten rock).

Aerobic respiration has 3 stages: glycolysis, Kreb's cycle, electron transport
chain. What happens in each stage? How many ATP molecules made during
each stage?
What happens in each stage?
GLYCOLYSIS: "In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule. In these reactions, ATP is made, and NAD+ is converted to NADH." (Khan Academy)
KREB'S CYCLE: "This is a central driver of cellular respiration. It takes acetyl CoA—produced by the oxidation of pyruvate and originally derived from glucose—as its starting material and, in a series of redox reactions, harvests much of its bond energy in the form of NADH, FADH2, and ATP molecules. The reduced electron carriers—NADH and FADH2—generated in the TCA cycle will pass their electrons into the electron transport chain and, through oxidative phosphorylation, will generate most of the ATP produced in cellular respiration." (Khan Academy)
ELECTRON TRANSPORT: "In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient." (Khan Academy)
How many ATP molecules made during each stage?
GLYCOLYSIS: 2 ATP
KREB'S CYCLE: 2 ATP
ELECTRON TRANSPORT: 34 ATP
