What is important information about S waves ?

The marine multicellular protists including the larger brown algae belong to the

Finger [1]

Options for the question have not been given. They are as follows:

A. dinoflagellates.

B. Choanoflagellida.

C. Stramenopiles.

D. euglenoids.

E. foraminifera.

Answer:

C. Stramenopiles

Explanation:

Stramenopiles or heterokonts are a part of Chromista kingdom. They comprise of both unicellular and multicellular protists. They are characterized by presence of two dissimilar flagella in the motile life cycle stage. Their chloroplast is also surrounded by four membranes which indicates origin from symbiotic relationship. They include many classes like diatoms, golden algae and brown algae. Brown algae belongs to the class Phaeophyceae. They are marine multicellular algae and are commonly known as seaweeds.

Answer:

To understand “Untouchability” you need understand our varna-vyavastha or simply called “Caste System”. Caste does not mean or is not the right translation for Varna/Jaathi/etc….. We(Hindus) had our varna-vyavastha (vv) based on the persons capabilities/skill/knowledge/understanding nature/patience & many more…..

As a group head (village/society/land), people needed to be divided to different functions of life…..

To survive, we need food. So gatherers/foragers were formed. Slowly this group increased to others ways/modes of food gathering, such as farmers, shepherds, etc…

In the meantime, while few were producing/collecting food items, people were needed to manage the production & distribution.

Very good, so far. But, people can’t eat the same stuff, every day & do the same job, as well. Getting bored. So, intelligence/creativity was needed. People with innovative minds gathered together & formed certain recipes/methods/etc…. Slowly this became tradition/culture/etc.

Now comes the problem. Intelligent/Innovative people are good at this. “How to control them?” is the question. So people with creativity/innovation/intelligence/etc & physical skill/strength were required. They had knowledge of the previous 3-types of works of life. Additional qualification was their physical strength & skills. These were few who had the ability to hunt, as well. Be it day or night.

In every walk of life, there are people who make mistakes or commit a crime. These people need to be punished. But, if we keep them within the village/land premises, they might not realize their mistakes or repent for their crimes. So a separate location is required. Problem is, if we keep them enclosed outside of society like in a jail, they will behave/become more like animals/savages. It is human nature. So, a new society needs to be formed, where these people can make their living, but still face punishment.

These type of people are basically worker class. Hence, these were called Sudras/Soodras.

These type of people are merchants. Hence, these were called Vysyas.

These type of people are administrators. Hence, these were Brahmins.

These type of people are rulers/kings. Hence, these were Kshatriya. Kshatriya means one who has warrior/soldier/fighter qualities/capabilities/etc.

These type of people are outcasts. Hence, the “Untouchables”

What forms of nitrogen and carbon can be used by plants?.

AlladinOne [14]

Answer:

Nitrate is the form of nitrogen most used by plants for growth and development. Nitrate is the form that can most easily be lost to groundwater. Ammonium taken in by plants is used directly in proteins. This form is not lost as easily from the soil

What some limitations found in photosynthesis experiment with the use of dicotyledous leaf ?

PolarNik [594]

Answer:

The history of net photosynthesis and transpiration per unit leaf area was determined for intact soybean leaves from their unfolding to senescence during flowering and pod filling on untreated (podded) and partially depodded plants growing in a glasshouse. Leaf diffusive resistances to CO2 were calculated and a water use efficiency parameter was derived (net mass of carbon dioxide fixed per unit mass of water transpired per millibar vapour pressure deficit). Net photosynthesis and transpiration behaved similarly through all stages of leaf development. A number of peaks were evident in these parameters. The first was associated with leaf expansion and occurred when the leaf reached its maximum area. The second peak coincided with flowering of the plant and later peaks occurred during pod filling. Stomatal and mesophyll resistances also exhibited similar behaviour during the life of the leaf; the possible causes of this linkage are discussed. Water use efficiency increased rapidly up to the time of full lamina expansion. Thereafter, it rose slowly or remained stable until leaf senescence approached, when the efficiency declined. Net photosynthesis and transpiration of leaves were very similar in both podded and partially depodded plants. It appears that to prevent a shortage of assimilate during flowering and pod filling, photosynthesis may be maintained or increased in some leaves and the response is not related to the number of pods available for filling. The increases in photosynthesis were correlated with both higher stomatal and mesophyll conductances. Mechanisms by which the plant may control leaf photosynthesis are discussed.
