Ddt was widely used as a pesticide for 20 years. Its use was banned after studies showed severe side effects were evident in hum

emmasim [6.3K]

Answer:

One major side effect of DDT was the extreme damage to bird populations. DDT caused the shells of bird eggs to become extremely thin, which made them prone to breaking from minor disturbances and failing to thrive due to temperature regulation issues. It also slowly poisoned animals, especially birds that fed on insects that were poisoned by DDT. A notable bird species that was affected by DDT is the bald eagle. At one point in the 1960s, bald eagles nearly went extinct due to various effects of DDT. The threat of one of the most recognizable animals in America going extinct led to lawmakers trying to ban DDT.

The yellow ring inside the bacterial cell represents the bacterial DNA. Why does this structure disappear by step 3 of the lytic

adell [148]

Answer:

The bacterial DNA gets degraded at step 3 of the viral lytic cycle.

Explanation:

Viruses are organisms that are incapable of replicating on their own, hence, they require a living host which they infect and use its replicational ability to reproduce theirselves. The infection cycle of this virus is regarded as its replication cycle. Viruses employ either the LYTIC or LYSOGENIC cycle for infection.

The lytic cycle involves killing of their host cell at the end of the cycle. Generally, the cycle starts with the attachment of my the virus to the cell membrane of its host using specific receptor sites (step 1). It then penetrates the host cell as seen in step 2.

After penetration, the virus then secretes certain degrading enzymes called ENDONUCLEASES that degrades the bacterial DNA. After which the virus uses the replicational and gene expressing ability of the host to transcibe its genetic material and replicate itself. This process called SYNTHESIS occurs in step 3.

Hence, the yellow ring in the image that represents bacterial DNA disappears in step 3 (synthesis stage) because it gets degraded by viral digesting enzymes.
