Correct Answer: C. Macronutrient

Correct Answer: A. both feed on fishes

Correct Answer: B. have a similar structure and function

Correct Answer: A) CO2 and ethanol

Explanation

Anaerobic respiration is a type of cellular respiration that occurs in the absence of oxygen. Yeast is a type of microbe that can carry out anaerobic respiration. In anaerobic respiration, glucose is broken down into simpler substances to produce energy. The question asks what are the products of anaerobic respiration in yeast. The options provided are CO2 and ethanol, CO2 and H2O, CO2 and O2 , CO2 and glucose, The correct answer is option A, CO2 and ethanol. This means that when yeast carries out anaerobic respiration, it produces carbon dioxide and ethanol as waste products. It is important to note that anaerobic respiration is less efficient than aerobic respiration, which occurs in the presence of oxygen. This is because aerobic respiration can produce more energy from the same amount of glucose. In summary, anaerobic respiration in yeast produces carbon dioxide and ethanol as waste products.

Correct Answer: C. binary fission

Correct Answer: D. 17%

Explanation

According to Chargaff's rule, DNA nucleotides pair in a 1:1 ratio. Therefore, if we know how much of the particular gene is made up of one nucleotide, we can extrapolate that known variable to find the other three unknown variables. To do so, you must remember that adenine pairs with thymine, and cytosine pairs with guanine (A-T, C-G), and that since the ratio between each pair is 1:1 then a gene with 33% adenine must also have 33% thymine. Combine these numbers and subtract from 100: the number leftover is the % of total cytosine and guanine in the gene. 100% - 66% = 34% Finally, since we know that 34% of the DNA is both C and G, and that the ratio between C-G is 1:1, C and G must both be 17%.

Correct Answer: C. Cell membrane

Correct Answer: A. Pileus

Correct Answer: B. contractile vacuole

Correct Answer: C. Cochlea

Explanation

The cochlea is a spiral-shaped structure in the inner ear that is filled with fluid and lined with cells with very fine hairs. These hairs move when the fluid in the cochlea moves, thereby converting sound vibrations into nerve signals that the brain can interpret. Therefore, the correct answer is 'Cochlea.' The eardrum and ossicles help to transmit sound vibrations to the cochlea, but it is the cochlea that transmits these vibrations as signals to the auditory nerve.
