Explanation:
base on the person opinion
Answer:
the female sea otter has 1
Explanation:
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.
Answer:
The correct answer is E-processing of exons in mRNA that results in a single gene coding for multiple proteins.
Explanation
Splicing is the process where introns are cut out of the mRNA so only the coding parts for proteins. In this way, genes can code for many proteins, depending on how the amino-acids are arranged.
Answer:
B. Oncogene
Explanation:
A gene that makes the body cells to divide in an uncontrolled manner is called an oncogene. An oncogene is responsible for the development of tumors due to disturbed regulation of cell division. The gene src makes the cells to enter the process of cell division in response to the growth factors.
However, the mutant src gene does not require the presence of growth factors and signals the cells to enter the process of cell division even in the absence of the growth factors. Since the mutant src gene causes uncontrolled cell division, it represents an oncogene.
