Answer:
Double-stranded DNA
Explanation:
If a virus requires to transport its genome in the nucleus to produce viral protein then the viral genome content must be DNA. This DNA of the virus will use the RNA polymerase of the host cell and will first convert into mRNA in the nucleus.
Then the mRNA of the virus will come out of the nucleus because the protein synthesis takes place outside the nucleus and in the cytoplasm. So in the cytoplasm by using host translational machinery the viral mRNA will code for viral proteins. So the correct answer is double-stranded DNA.
Answer:
Homeostasis is defined as the state of body in which body maintains several chemical and physical changes inside the body affected by external factors.
Negative feedback loop includes a sensor, stimulus, control center, and effector which is used to control homeostasis.
A negative feedback loop is a reaction that reduce an excessive response and maintain the functions within the normal range. for example: if temperature and blood glucose level increases in the body, negative feedback loops control both the variables and maintain homeostasis.
Hence, negative feedback loops used to control body homeostasis.
Answer:
Changes involved in succession
Explanation:
In the field of ecology, community composition changes over time. The study of succession addresses this change, which can be influenced by the environment, biotic interactions, and dispersal. This change in community composition over time is termed succession.
The first statement is correct. This is because plants transfer light (which is absorbed by chlorophyll) to chemical energy to convert carbon dioxide and water into glucose and oxygen.
Answer:
Titaallik
Explanation:
One of the major archeological findings what that of the Titaallik. This is a monospecific genus of extinct sarcopterygian from the Late Devonian Period, roughly about 375 Mya. This species helped help us links marine mammals to their terrestrial ancestors since the Titaallik was a half-species which was a snake with legs. Thus linking modern snakes to their amphibious ancestors from which they descended.
