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.
As a person ages, scoliosis may develop resulting in an abnormal spinal curvature and 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.

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.

Sugar
Explanation:
The correct answer would be sugar.
Respiration generally involves the metabolic breakdown of carbohydrates to generate energy (in the form of ATP). It is a multi-step process that can summarily be represented by the equation below:
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + energy[/tex]
As a rule of thumb, the higher the respiratory quotient of a substrate, the higher the energy that will be generated if such a substrate is utilized for respiration. By definition, the respiratory quotient of a substrate is the ratio of carbon dioxide to oxygen produced or consumed to breakdown the substrate.
Carbohydrates are known to have the highest respiratory quotient while other molecules follow in varying degrees. Other substances apart from carbohydrates have to undergo one or two metabolic processes before they can enter the respiratory pathway, thereby reducing their efficiencies when compared to carbohydrates.
When crude oil is distilled, it is separated into categories. What are those categories characterized by?
Answer:
Differences in their boiling points
Explanation:
When crude oil is distilled and separated into categories, the categories are characterized by the differences in their boiling points.
At different boiling points, each of the fraction will separate out.
Crude oil is made up of different fractions of hydrocarbons. As the chain length of the hydrocarbon increases, the volatility reduces and boiling point increases. Components with short carbon lengths rises out from the column first and are cooled and extracted. The categories are thereby, classified based on differences in their boiling points.A concentration gradient is ________.
5 points
High concentration
Low concentration
A concentration difference
equal concentration
Answer: The process of particles, which are sometimes called solutes, moving through a solution or gas from an area with a higher number of particles to an area with a lower number of particles. The areas are typically separated by a membrane.

Compare a cup of hot coffee with the Pacific Ocean. Which statement about thermal energy and temperature is correct?
A.
Water in the Pacific Ocean has more thermal energy and a higher temperature.
B.
Water in the Pacific Ocean has less thermal energy and a lower temperature.
C.
Water in the Pacific Ocean has less thermal energy and a higher temperature
D.
Water in the Pacific Ocean has more thermal energy and a lower temperature.
Answer:
D. Water in the Pacific Ocean has more thermal energy and a lower temperature.
Explanation:
Thermal energy is a form of kinetic energy which deals with the movement of molecules in a medium.
Temperature is a measure of the heat energy of system. Heat is the average kinetic energy of the particles of a medium.
The pacific ocean has more molecules contained in it which is the reason why it will have more thermal energy. The cup of coffee has few particles will be at a higher temperature. Since the average kinetic motion is high compared to that of the ocean.Can someone please answer

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.

What are 2 pieces of evidence that support the Continental Drift Theory? Explain how they support the theory.
Answer:
Explanation: In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth's surface. The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
The fit of the continents; the dispersion of ancient fossils, rocks, as well as highlands; and the positions of ancient climatic zones were all evidence for continental drift.
What is Continental Drift Theory?Continental drift was a groundbreaking theory that explained how continents shift position on the Earth's surface.
Alfred Wegener, a geophysicist and meteorologist, proposed the theory in 1912, but it was rejected by mainstream science at the time.
Plate tectonics caused continental drift over millions of years. Plate tectonics also explained how plate movement causes volcanoes and earthquakes, as well as how continent collisions create massive mountain ranges.
Continental drift was demonstrated by the fit of the continents, the dispersion of ancient fossils, rocks, and highlands, and the positions of ancient climatic zones.
Thus, these are the evidences that support the Continental Drift Theory.

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.
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).
