Answer:
E. are a dormant form of a bacterium AND are formed by members of medically relevant groups of bacteria.
Explanation:
Endospore is a structure formed by some bacteria when exposed to unfavorable conditions like lack of nutrition. It is a dormant non reproductive structure. When the bacteria is exposed to favorable condition, it regains its natural vegetative state. Endospores contain a large amount of dipicolinic acid which helps in the bacteria's dormancy.
Endospores are medically important because they are resistant to all the methods of destroying bacteria like UV radiation, desiccation, disinfectants and freezing. Two endospore forming genus, Bacillus and Clostridium are reason for many diseases. <em> Bacillus anthracis </em>causes anthrax which is very fatal to humans. <em>Clostridium botulimum</em> causes botulism and <em>Clostridium tetani </em>causes tetanus.
Answer:
Mitosis is the process in which the nucleus of a eukaryotic cell divides. During this process, sister chromatids separate from each other and move to opposite poles of the cell. This happens in four phases, called prophase, metaphase, anaphase, and telophase.
Explanation:
<span>When a cell is "at rest" it is in a state called the resting potential.
In this state, neurons are more negatively charged ions inside the cell than outside the cell.
A resting neuron also known as non-signaling neuron. A neuron is made up cells.There are many types of cells in the body. The approximate value of cells is 37.2 billion in our body.</span>
<span>Nucleic acids are DNA and RNA
Proteins provide both functional and structural functions to cells
Carbohydrates provide short-term energy storage to cells
<span>Lipids provide the long-term storage</span></span>
