In liquid media or broth difference between dry and wet will give biomass of the Epulopiscium.
Explanation:
Biomass of bacteria can be measured by dry or wet mass. Bacteria numbers can be counted by spread plate method under the microscope.
In solid media the colonies obtained are diluted and number of cells will be seen by plate count method or on automated cell counter. The number would help calculate biomass
The biomass will be calculated by measuring wet and dry mass. Equipments required will be:
hydraulic gravity convection oven and centrifugation set up.
A cellulose acetate filter membrane is used which is 47 mm in diameter and 0.45 micron of pore size.
The cells grown settles down due to gravity. They are stirred to evenly spread in the broth and is kept in centrifuge.
The cells obtained after centrifugation will be taken and wet weight is obtained.
To obtain dry weight the cells are placed in oven for 6 hours to 24 hours. The resultant cells are weighed and dry weight obtained.
Biomass will be calculated by subtracting the wet mass to dry mass. This way biomass is obtained in epulopisicuium. Here the cells will be of different size so on centrifugation 2 or more phases of cells can be seen due to gravity change.

<span><span>#1) What would be the pros and cons of using Linnean and modern classification system?
</span><span>Answer: The pros of using the Linnean classification system is that it conveys a very detailed information about the species and the closest relatives of living things. It helps scientists to understand the complex relationships. A con is that it takes a very large amount of information and time for this system to develop.

Hhv-5 infectious in pregnant women can be particular concern because this virus can be teratogenic.
<h3>
What is teratogenic?</h3>
- Teratology is the study of aberrant physiological development across the whole life cycle of all species, including plants.
- Dysmorphology is a branch of medical genetics that focuses on the classification of congenital deformities.
- Teratogens are substances that, when exposed to a pregnant woman, may result in physical or functional abnormalities in the human embryo or fetus.
- Such substances include, for example, alcohol and cocaine.
- A teratogen is an agent that increases a baby's risk of developing a birth defect or can actually cause one.
- They are items to which a mother might be exposed while expecting.
- Teratogens can result in neural tube abnormalities like spina bifida during this time.
- Throughout the entire pregnancy, certain organs are vulnerable to teratogens.
- The baby's brain and spinal cord are included in this.
- Alcohol can be harmful at any point during pregnancy since it has an adverse effect on the brain and spinal cord.
