Mutations are simply a change in genes. So mutations usually result in variation of an organism that can be good or bad. Some mutations can result in physical and mental disorders like Stockholm disease or down syndrome, Where else some mutations can cause immune to diseases that are harmful.
Explanation:
Comparing prokaryotes and eukaryotes
All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.
Answer:
Physiology, behavior and morphology are considered as phenotype of an individual as these attributes can be observed. Example of phenotypes include wing length, hair color, skin color and height.
<u>There are basically two factors that influence the phenotype:</u>
<u>(1) Genotype or Genetic information of the individual:</u> Some of the phenotypes such as height and skin color are transmitted genetically from generation to generation. Genetic information is the transfer of genes that carry some of the specific genetic information and pass it to another generation which is visible in their phenotype.
(2)<u> Environmental influence:</u> As the phenotype attributes are variable so they are highly influenced by the environment or surrounding they are living. Environmental condition such as temperature, diet, humidity, oxygen levels, and the presence of mutagens affects the phenotype of an individual.
Hence, Genotype and environmental factors influence an individuals phenotype.
Answer:
Protein has many roles in your body. It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance. Your body needs protein for growth and maintenance of tissues. Some proteins are hormones, which are chemical messengers that aid communication between your cells, tissues and organs.
These are small eukaryotes
