Answer:
The statement is FALSE.
Explanation:
In genetics, expressivity refers to the amount of variation in a non binary phenotype across individuals, who are carrying a specific genotype. Scientists believed that variable expressivity is controlled by different factors such as environment, genetics and lifestyle choice. An example of expressivity is a series of blue eye color that has different shades of blue. Thus, expressivity is not about balanced genetic output but varied genetic expression.
Answer:
"The ciliary body is a circular structure that is an extension of the iris, the colored part of the eye."
Explanation:
Answer:
True
Explanation:
According to Mendelian's law of inheritance, the dominant allele is the allele that is expressed in an individual while the recessive allele are usually not expressed in the phenotype of an individual.
If a parents is dominant for a particular allele of tallness and recessive for a particular allele of shortness it is observed that the dominant allele is what is expressed in the phenotype of the offspring and inherited in simple Mendelian fashion by the offspring.
Microorganisms can be divided into two groups:
1. Archea
• Archea are prokaryotic unicellular organisms without cell nucleus or other membrane bound-organelles.
• Their membrane is built from ether lipids, which differs them from bacteria’s cell membrane.
•
2. Bacteria
• Bacteria are also unicellular prokaryotic organisms.
• Bacterial cell membranes are made from phosphoglycerides with ester bonds. Bacterial genome is in a form of circular chromosome.
• They reproduce by binary fission or by budding.
Besides, prokaryotes (Archea and Bacteria) a large number of eukaryotes are also microorganisms. Unicellular eukaryotes contain organelles such as the cell nucleus, the Golgi apparatus and mitochondria. Usually, they reproduce asexually by mitosis. An example of eukaryotic microorganism is Protist.
