Upon centrifugation, particles sediment at different rates due to their physical properties. Tropomyosin is a rod-shaped protein

with a mass of 70 kDa and a sedimentation coefficient of 2.6S. Hemoglobin is a spherical protein with a slightly smaller mass of 65 kDa, but a much higher sedimentation coefficient of 4.31S. Which property of tropomyosin accounts for its slow sedimentation?

Answer:

Elongated shape

Explanation:

Centrifugation separates molecules on the basis of angular motion.

Due to spherical shape, the value of 'f' is lesser for a spherical protien than the rod shaped one.

Hence the sedimentation coefficient for an elongated protien is 2.6S while htat of a spherical protien is 4.31S.

Hence its elongated shape results in slow centrifugation.

Some of the important principles of centrifugation are as follows :

  • The greater the mass, the more is the sedimentation rate i-e the one with greater mass will move down more rapidly as compared to the one with les mass.
  • Shape of particles also effect it, the rounder the particle, the lower frictional coeeficient.
  • Density of particles
  • Density of fluid

Select the correct answer. in which terrestrial biome would you find precipitation of 300 to 900 millimeters (mm) each year? a.
Jlenok [28]

In coniferous forests, the terrestrial biome receives precipitation of up to 300 to 900 millimeters (mm) each year.

Coniferous forests mainly consist of conifers and grow trees that produce thick needles and cones instead of growing flowers and leaves.

These are evergreen plants and stay green, healthy, and sustainable all year long.

In spite of flowers, these trees bear needles annually.

Moreover, conifers are very adaptive trees that can grow in very cold and dry climate zones.

It is due to their adaptability that they can survive all year long without losing a life.

Siberian fir, Dahurian, and Siberian larches are examples of confer forests.

nikdorinn [45]
The correct answer is <span>the contribution an individual makes to the gene pool of the next generation relative to the contribution of another individual.

Each individual in a population has an absolute fitness which is a measure of the successfulness of an individual in reproducing and leaving viable offspring. The relative fitness, on the other hand, is the relative fitness of the individual compared with another individual, usually the one with the highest fitness. </span>
