Why is oxygen consumption a good measure of respiration in yeast?

Biology
1 answer:
Dafna1 [17]3 years ago
3 0

Answer:

The respiration of a suspension of yeast cells was measured by determining the decrease in pressure of the gas above the cell suspension. The apparatus was arranged so that the gas was confined to a constant volume, 16 cm3 and the entire pressure change was caused by the uptake of oxygen by the cells. The pressure was measured in a monometer, the fluid of which had a density of 1.034 g/cm3. The entire apparatus was immersed in a thermostat at 37. In a 30 minute observation period the fluid in the open side of the manometer dropped 37mm. Neglecting the solubility of oxygen in the yeast suspension, compute the rate oxygen consumption by the cells in mm3 of O2 (STP) per hour

The presence of over 700 genes involved in height determination is an example of (a) ______________.
Ira Lisetskai [31]

The presence of over 700 genes involved in height determination is an example of a polygenic trait.

<h3>What is a polygenic trait?</h3>

A polygenic trait refers to a trait that is determined by multiple genes rather than by only one gene. This is opposite to a monogenic trait that is determined by only one gene.

<h3>What are some examples of polygenic traits?</h3>

In humans, some examples of traits that are determined by multiple genes are:

  • Height
  • Hair color
  • Skin color

Based on this, heigh is a polygenic trait.

PLEASE HELP ASAP!!!!
marin [14]

Answer:

B. Smaller fragments travel faster and farther than larger fragments.

Explanation: Shorter molecules move faster and migrate farther than longer ones because shorter molecules migrate more easily through the pores of the gel. This phenomenon is called sieving. [2] Proteins are separated by charge in agarose because the pores of the gel are too large to sieve proteins.
