Answer:
True.
Explanation:
Bryophytes lack the conventional vascular tissues which usually contain the substance lignin. Without vascular tissues, these plants have no means of transporting water and/or nutrients from their lower organs to the higher organs which explains their limited height.
Hope this helps! Brainliest? Anyways have a great day!! :))
B is your answer for that question
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;
B is the product of enzyme 1 and the substrate for enzyme 2.
Explanation;
-Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy.
-The molecules upon which enzymes may act are called substrates and the enzyme converts the substrates into different molecules known as products.
The expected assessment findings for a herniated lumbar disk are as follows:
a) Fallacies in the soft tissues. Also there can be muscle atrophy
b) The inability to bend or there is limited ability of bending
c) There might be occurrence of pain in lumbar and cervical herniation
d) There can be reduced tenderness and weakness in the affected region
e) There are high probabilities of adverse impact on the posture.
