Summary Introduction

To analyze:

Why the development of the membrane system was an important phase in the origin of life.

Introduction:

The membrane system refers to the membrane bound organelles seen in all eukaryotic cells.

Expert Solution & Answer

Answer to Problem 1SA

Correct answer:

Option (a): amino acids.

Explanation of Solution

The formation of the first membrane around chemical components lead to the formation of the first cells. This started life on earth. When membrane systems developed around cells, it allowed more complexity to come into life processes.

The different chemical components within cells began to be enclosed within lipid membranes. This created specialized structures called organelles.

The development of the cell membrane allowed the cell to regulate the molecules that could interact with the cell components, allowing access to required chemicals, while inhibiting others that were injurious to the cell and its components.

Specialized functions evolved in the cells, and the cells in turn grew specialized for various functions. This may have been what led to the evolution of multicellular organisms. This development is considered an important phase in the origin of life.

Conclusion

The separation of different chemical components within a cell by membranes lead to the evolution of organelles. This is an important phase in evolution because it led to the increase in complexity of life processes.

Linkage in common bean Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population…
