Explain how the fluid mosaic model describes the plasma membrane

Biology

Zepler [3.9K]3 years ago

5 0

Answer:

S.J. Singer and Garth L. Nicolson proposed the fluid mosaic model to describe the plasma membrane structure. They explained that the plasma membrane is a mosaic of carbohydrates, phospholipids, carbohydrates, and proteins.

This mosaic nature provides the fluid characteristic to the plasma membrane. This fluid behavior of the plasma membrane allows the movement of phospholipids and protein in the plasma membrane.

This movement of membrane components plays an important role in the transport of molecules across the cell.

AVprozaik [17]

Answer:

In Labrador dogs, black coat is dominant to chocolate, normal vision is dominant to progressive retinal atrophy (PRA), and normal hip joint is dominant to hip dysplasia. All these genes assort independently. Two dogs that are heterozygous for alleles of all three genes are crossed. Using rules of probability (not a Punnett square), what is the chance that the first pup born to these dogs will be chocolate, have normal vision, and have normal hip joints?

BbVvHh x BbVvHh= BBVVHH, BbVvHh, BbVvHh, bbvvhh

Bb= black coat dominant

Vv= Normal vision dominant

Hh= Normal hip join dominant

probability of having a first born of these dogs will be chocolate, have normal vision and have normal hip joint is 0

Explanation:

As the punette square gives 3:1 phenotype having three black coat, normal vision and normal hip joint and one chocolate, progressive retina altropy and hip dysplasia

The organismal theory teaches that _____.

natita [175]

Answer:

A. the basic unit of life is the organism

Explanation:

According to the organismal theory, organisms are the basic unit of life. The organismal theory contradicts the cell theory of life. The organismal theory states that some of the organisms do not have distinct cells. For example, fungi.

Since the cells in the multicellular organisms are interconnected by one or other means, organisms are the structural unit of life; not the cells.

The organismal theory states that irrespective of the level of body organization present in an organism, all the components such as cells, tissues, organs, etc. work together to facilitate growth and development of whole organisms.
