As a scuba diver descends toward the bottom of the ocean, she experiences the sensation of her ears "popping." Based on your observations from the Can Crush Lab, why would this happen?
A. Decreased pressure inside the diver's oxygen tank causes pressure on the diver's ears.
B. Increased pressure inside the diver's oxygen tank causes pressure on the diver's ears.
C. Pressure increases on the diver as the diver descends deeper underwater.
D. Pressure decreases on the diver as the diver descends deeper underwater.
Answer:
C. Pressure increases on the diver as the diver descends deeper in the water.
Explanation:
Due to the pressure of the water on the diver she feels the pressure on her ears. Just like the same feel of going up a steep hill.
Answer:
C. Pressure increases on the diver as the diver descends deeper in the water.

Which of the following is the most likely outcome of Leigh syndrome on affected mitochondria?
Answer:
The loss of this protein reduces the formation of normal COX complexes, which impairs mitochondrial energy production. The most common mtDNA mutation in Leigh syndrome affects the MT-ATP6 gene, which provides instructions for making a piece of complex V, also known as the ATP synthase protein complex.
You are conducting a photosynthesis experiment to determine how much oxygen is produced over a 24-hour period of time. You are measuring the oxygen production every hour for 24 hours.
Answer:
Measure only daytime.
Explanation:
It is useless to measure the oxygen production every hour for 24 hours because oxygen is produced during day time due to the presence of photosynthesis process. Oxygen is produced in large amount during photosynthesis, some oxygen is used in respiration while the remaining diffuse out from plant body through stomata. After vanishing sunlight, the photosynthesis process stop and no production of oxygen occur. So only measure oxygen production at daytime as compared to every hour for 24 hours.

What is migration ?Migration can be defined as the movement of a large number of organisms from one place to another place, there are many reasons for migration.
The term migration is used to define regular and periodic movements of the population away from or back to their place of origin, it can be up different types.
Some migration can occur for an entire lifetime and it happens to be a single migration of an individual. This is in the case for the Pacific salmon. On another hand, an individual may migrate frequently, like many of the migratory birds and other mammals.

9. AAC is a codon that codes for the amino acid:
serine
lysine
asparagine
isoleucine
Answer:
asparagine
Explanation:
take a look at the graph attached, it helps identify codon sequences.
The codon AAC codes for the amino acid asparagine. Asparagine is a non-polar, neutral amino acid that is found in all living cells. Hence option C is correct.
It is involved in a variety of cellular processes, including protein synthesis, cell signaling, and energy metabolism.
The other answer choices are incorrect. Serine is coded for by the codon AGU or AGC. Lysine is coded for by the codons AAA or AAG. Isoleucine is coded for by the codons AUA, AUC, or AUU.
Therefore, option C) asparagine is correct.

what do you observe at low temperature medium temperature and high temperature
The temperature of a body can be related to the energy transferred between the particles of the body. Hence, temperature is directly proportional to the energy of the particles in the sample.
The kinetic energy possessed by the particles in a sample is highest at the highest temperature attained by the body. The kinetic energy drops as the temperature drop s from high to medium to low temperature. Hence, the low temperature samples have very low kinetic energy.Therefore, the energy possessed by the particles of a sample is directly proportional to the temperature of the sample.

____are compounds that produce H+ ions in solution.
Answer:
An acid is a substance or compound that releases hydrogen ions (H+) when in solution. In a strong acid, such as hydrochloric acid (HCl), all hydrogen ions (H+), and chloride ions (Cl-) dissociate (separate) when placed in water and these ions are no longer held together by ionic bonding.

What conditions were necessary for the first matter to form in the Universe?
Explain why
Answer:
hydrogen and helium couldn't form until the universe had cooled enough to allow their nuclei to capture electrons, about 380,000 years after the Big Bang. Within about 3 minutes after the Big Bang, conditions cooled enough for these protons and neutrons to form hydrogen nuclei.

Glucose is a building block of carbohydrates. Which of these best describes glucose?
A. nucleotide
B. protein
C. monosaccharide
D. lipid
Answer:
monosaccharide
Explanation:
Glucose is called a simple sugar or a monosaccharide because it is one of the smallest units which has the characteristics of this class of carbohydrates.
Glucose is the simplest monosaccharide which cannot be broken down further. Thus, option C is correct.
What is Glucose?Glucose is the primary component of carbohydrates. Glucose is a monomer made up of carbon, hydrogen and oxygen. Molecular formula of glucose is C6H12O6.
The functional group in glucose is an aldehyde present at the first carbon atom.
Glucose is called monosaccharides because it cannot be hydrolysed further. It is the simplest carbohydrate also referred as simple sugars.
Glucose molecules are chiefly linked together forming a glycosidic bond by removal of water molecule and form a disaccharide.
Glucose is chiefly produced by plants during the process called photosynthesis.
Glucose is the key component in metabolism. It provides energy to the body cells to carry out physiological activities. Glucose is found in blood.
Excess of glucose in the blood results in a medical condition called diabetes. It can be life threatening if not managed on time.
