Answer: A geneticist studies a series of families in which both parents are normal and at least one child has albinism. The geneticist reasons that both parents in these families must be heterozygotes and that albinism should appear in  of the children of these families. To his surprise, the geneticist finds that the frequency of albinism among me children of these families is considerably greater "Than . Can you think of an explanation for the Thigher-than-expected frequency of albinism among These families?

Upon centrifugation, particles sediment at different rates due to their physical properties. Tropomyosin is a rod-shaped protein
polet [3.4K]

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

skad [1K]
The environment is studied at different levels & stages.
Biosphere: The biosphere is the zone in which life exists. It consists of the atmosphere& the hydrosphere alongwith the earth surface where living beings live. 

The biome is a community of plants and animals (flaura & fauna).
Community: A community is a group of people/living beings who live in a specific location. It is used to describe two or more populations of different species that exist at same place.
Population: A population is the multiple individuals or living organisms of a single species that live in an area. 
The populations are formed by lalrge number of groups of organisms.
Group of populations form communities. The group of all communities form a biome, which exist in the biosphere.
