After the star's outer layers are expelled, the density of the remaining material is typically too low to provide adequate energy to sustain the hydrogen-burning shell's nuclear temperatures, and the remaining star easily contracts to form a white dwarf (a star with a density equal to the Sun, but a diameter equal to the Sun).

Answer: Cellular respiration is the process by which microorganisms obtain the energy available in carbohydrates. They take the carbohydrates into their cytoplasm, and through a complex series of metabolic processes, they break down the carbohydrate and release the energy. The energy is generally not needed immediately, so it is used to combine ADP with phosphate ions to form ATP molecules. During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons. This oxygen gas is identical to the oxygen gas given off in photosynthesis.

3. In one population, 18 individuals have long hair and 182 individuals have short hair. It is known thatmating has been random
pishuonlain [190]

Answer: p (short hair) = 0.91 and q (long hair) = 0.09

Explanation: In the population, short hair is a feature of domnant allele, because there are more short haired individuals than with long hair. In genetics, p is the frequency for dominant allele and q is for recessive allele.

For this question, short hair is allele L and long hair is allele l

So, the frequency of short hair is p and of long hair is q.

To calculate the frequencies:

Frequency of allele L = (number of copies of allele L in population) / (total number of L/l gene copies in population)

p = 182/200 = 0.91

The same formula goes for the recessive allele, so:

q = 18/200 = 0.09

Thus, the frequencies of hair allele are 0.91 and 0.09 for short and long, respectively.
