Answer:
<u>Option-(True):</u> The methodology used to discover the pattern of evolution among an assemblage of species is based on the assumption of descent with modification.
Explanation:
<u>Evolution and patterns of evolution:</u>
The phenomenon of evolution is very interesting as it can any two different species back to a common origin or ancestors. While the process of evolution does not occur in few years or centuries, as it takes millions of years for any specie to evolve from a less developed form of body or any system to a more complex or advance form.
Now, evolution occurs in many forms or patterns. As it species can originate from a single ancestor or descendant, while the evolution can occur inside the organism may occur in different patterns. These patterns are as follows:
- <u>Divergent Evolution:</u>The divergent evolution occurs when the species originated from a single ancestor or descendant results in different forms of organisms. As it brings diversity among the species belonging to same ancestors or origin. For example, the humans and apes.
- <u>Convergent Evolution: </u>The convergent evolution takes place inside the number of species when they are originated from the different species but they share the same medium or region to live in and share some of the similar resources between them. For example, The whales are mammals but they too live with the fish species inside the water.
- <u>Parallel Evolution:</u>When the evolved organisms or species are related to the different ancestors or descendants, as they share they do not share the same niche(way of life), as the species are unrelated to one another.
Chronic obstructive pulmonary disease (COPD) is the world's top cause of death for the greatest number of individuals, known for its chronic obstructive diseases, chronic bronchitis, and emphysema.
<h3>How genes impact on COPD?</h3>
- The precise causal process of COPD is still unknown, despite several attempts to discover biomarkers and pathways.
- In order to better understand the biological mechanism and network module underlying COPD, this study integrates information on biological interactions with information on gene expression.
- 49 genes were chosen using a sparse network-based technique from the peripheral blood mononuclear cell expression data of 136 participants, comprising 42 ex-smokers and 94 COPD patients.
- The findings indicate that these 49 genes may have an impact on COPD-related biological functions and molecular processes.

If your in alaska and do this experiment the weather conditions may affect the test results. if you go to australia the same can happen. there are many factors and variables in which an experiment can have different results.
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.
