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.

Answer:
True.
Explanation:
Therapeutic cloning is the technique of using cloning procedures to generate embryonic stem cells that can be applied for the damaged organ or tissue replacement without getting the chances of any rejection. This can be achieved by putting a diploid nucleus from a body cell to a enucleated cell. Then from that cell an identical organ can be developed.
This is because cells are not only characterized by their genetic material and other interior components but also by genes they express cells have to fulfill multiple different functions to be able to build complex multicellular organisms
Answer:
The mantle is solid.
Explanation:
The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers thick, and makes up 84% of Earth's total volume.
