What percent of the energy consumed by the larvae became biomass that is now available to the next trophic level?
likoan [24]

Answer

         About 10% energy is converted to biomass from one trophic level to another trophic level.

Explanation

        Food chain is composed of different trophic level which are classified on the basis of their mood of food obtain. These include  

1. Producers (photosynthetic)

2. Primary consumers (herbivore)

3. secondary consumer (Carnivore)

4. Tertiary consumer (carnivore)

5.Quaternary consumer (Carnivore)

6. Decomposer  

                     As larvae are hatched by insects which belong to second trophic level.  About 90% of energy in food is lost at each trophic level. As move down the trophic level the number of organism also decreases in each trophic level. Therefore, energy transfer from one trophic level to another is like a pyramid.

Which of the following was the major contribution made by Avery, MacLeod, and McCarty that strengthened the argument that the tr
galben [10]

The major contribution made by Avery, MacLeod, and McCarty was 'transformation of nonvirulent cells with a DNA extract was blocked only if DNase was added'. This observation supported the idea that the transforming agent in Griffith's experiment was DNA.

The Avery–MacLeod–McCarty experiment showed that DNA was the transforming agent observed in Griffith's experiment.

Griffith's experiment (1928) suggested that bacteria were capable of transferring genetic information (DNA) by a process of horizontal gene transfer called transformation.

While the bacteria were killed by heat, Frederick Griffith observed that the DNA had was taken up by II-R strain bacteria via transformation.

Avery–MacLeod–McCarty experiment observed that protease enzymes did not destroy the transforming agent (but DNAse destroyed this transforming principle), thereby suggesting that the transforming agent in Griffith's experiment was bacterial DNA.

Which is the main reason cells are replaced in the body?. The cells are too large.. The cells are inactive.. The cells are damag
anygoal [31]

The right answer is The cells are damaged.

Take the example of skin cells.  

The skin consists of two tissues:

* the outermost, the epidermis, resting on a vascularized connective tissue,

* the dermis.

In the epidermis, which includes several layers of cells, the outer layer is formed of dead cells that are desquamating and are constantly being replaced from proliferating basal cell cells. So, in normal conditions, the epidermis is in constant renewal.

On the other hand, when accidentally, the upper parts of the epidermis are damaged, for example, a slight abrasion or of a burn, the destroyed portion is regenerated (replaced) thanks to an accelerated proliferation of basal epidermal cells .
