Answer:
The correct option is a. lacks organelles beyond ribosomes.
Explanation:
All cells of higher organisms are bounded by a cell membrane (also called plasma membrane or plasmalema) and contain cytoplasm that surrounds one or more nuclei. Within the cytoplasm there are structures known as organelles, which are specialized in carrying out the metabolic processes of the cell, these cells are called eukaryotes. The prokaryotes are smaller, lack a differentiated nucleus and organelles. The prokaryotic cells are not internally divided by membranous walls, but consist of a single space.
Both prokaryotic and eukaryotic cells contain ribosomes. Ribosomes are organelles not delimited by membranes, these organelles are important since a cell makes all its proteins in its ribosomes.
Answer:
A. 
B. 1/4 or 25%
C. 1/4 or 25%
D. No
Explanation:
<em>Let the allele for color blindness be represented by c.</em>
A. <em>The genotype of a woman that is a carrier for color blindness = </em>
The genotype of a man with normal color vision = 
Crossing the two in a marriage:
x
From the result of the cross:
B. <em>1/4 or 25% of their children are expected to be color blind. </em>
C.<em> 1/4 or 25% of their children are expected to be carriers of the allele for color blindness.</em>
D. <em>No. The couple cannot have a girl that is color blind. Their female children could either be totally free of the color-blindness allele or be a carrier.</em>
<span>They are both a form of passive transport, meaning that no cellular energy is required for the processes to take place.
They both involve the movement of materials from an area of high concentration to an area of low concentration.
The main difference is one of definition. When WATER is diffusing from one place to another, like across a membrane, the process is called OSMOSIS. The movement of any other substance is just called DIFFUSION.
