Answer:
"nucleus" seems to be the correct answer.
Explanation:
- The nucleus seems to be a significant case wrapped through a double membrane that distinguishes these from the cytoplasm, the nuclear shell. The membranes combine throughout a few areas, allowing the interchange of substances between some of the cytoplasm as well as the nucleus, steps given designated "nuclear pores".
- The nuclear shell is consistent with either the concentrated endoplasmic reticulum, thereby bonding with either the nucleus.
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:
They travelled over 2000 miles by sea is exceptional about the role of early Polynesian cultures in exploration
Explanation:
These people have the exceptional talent having the excellency in boat making. And have the ability to sail across the sea with the help of currents, stars and with cloud formation. They have excellency with the highest skill in fishing and farming. Growing of fruit trees, growing of vegetables that also includes the growing of pigs, poultry and dogs. Islanders were having the talent of craftspeople, and cravings of wood, fibre and feathers for creating pieces of power and beauty.
It is false that to study Earth’s interior, geologists often rely on indirect methods, such as evidence from fossils. They rely on seismic waves and such.
Explanation:
No, they use seismic waves.A seismic wave is an elastic wave caused by an pressure such as an earthquake or an explosion. Seismic waves may travel either along or near the earth's surface (Rayleigh and Love waves) or by the earth's interior (P and S waves).
