As diatoms are made from silica this makes diatomaceous earth very abrasive, and so the sharpness enhances the particles as a pesticide. Diatoms are also useful in forensic studies. If a person has drowned then diatoms are able to enter the human body.
Answer: Option C - decomposers; they return biotic material to the abiotic component of the Earth
Explanation:
Decomposers are also known as SAPROPHYTES. They feed on and break down dead and decaying remains of plants and animals, thus enabling the release of certain compounds like ammonia, methane gas etc into the environment that then enrich/improve the soil fertility.
Answer:
Apoptosis of the infected cell.
Explanation:
Lytic and lysogenic are the two different types of viral life cycle. In the lysogenic part of life cycle the virus remain in the latent stage. In this stage, the genetic material of the virus gets attached with the host genetic material and gets replicated with the host genome. This stage is called prophase stage.
In lytic part, the viral gene transcribe and produce viral protein from which new phage particles are formed which do apoptosis of cell and gets released from the cell to infect other cells. So to be able to remain latent in the infected live cell HSV virus should shut down the apoptosis process of the infected cells.
Answer: Option A) This is an anabolic process.
Explanation:
An anabolic process is simply a constructive process in which complex molecules are synthesized from simpler ones.
Thus just as photosynthesis or glycogen synthesis that yields complex molecules, since DNA replication leads to the synthesis of long double-stranded polynucleotides wounded together from a single strand (as in semi-conservative replication); we can therefore conclude that it is a anabolic process.
