Answer:
The correct option is C) Viruses have a simple cellular structure
Explanation:
There is always a debate when considering viruses as a living thing or a non- living thing. Viruses comprise of a genetic material in the form of either DNA or RNA. They have a protein capsid and a tail. They can replicate inside a host cell by by using the host's synthetic machinery. Hence, these qualities make a virus to be considered as a living organism.
One of the main functions of villi is to absorb nutrients.
Answer:
The storage of calcium ions. (Ans. A)
Explanation:
T-tubule are the extension part of the cell membrane (which contains a large number of transporters, pumps & ion channels) which penetrate the central skeletal & cardiac muscle cell.
The primary function of the transverse tubule (T-tubule) is to storage and providing calcium ions for muscles contraction. T-tubule allows rapid movement of the action potential, & play a very important role in releasing cellular calcium concentration. Through this process, transverse tubule allows heart muscle cell contract forcefully by calcium (synchronizing) release from the cell.
The two samples must be independent and each must be drawn at random from any population. The two samples must be independent and each must be drawn at random from a healthy population.
At the very least, nominal scale data are required. There must be normal populations. There must be knowledge of the two population standard deviations. The samples depend on one another.
<u>What is nominal scale?</u>
A nominal scale is a measurement scale that is used to categorize events or things into distinct groups. This type of scale only needs one-of-a-kind identifiers to mark each separate category instead of requiring the usage of numerical values or categories ranked by class.
