Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. ... While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
Explanation:
RNA nucleotides form complimentary base pairs with DNA bases. Hydrogen and sugar-phosphate bonds form and the mRNA is synthesized.
Explanation:
The process of mRNA formed by DNA is called transcription. The genes coding for the protein is present on DNA as a nitrogenous base or nucleotides.
Transcription takes place inside the nucleus with the assistance of major enzyme RNA polymerase. In transcription 5'to3' single strand of RNA is synthesized which is complementary to the 3'to5' strand of DNA. The sequence of DNA has promoter sites which will be recognized and DNA will unzip to form transcription bubble. Several transcription factors and enzyme will be required to synthesize mRNA.
This mRNA after some modification would become primary transcript and pass on to the cytoplasm where protein synthesis will take place.
Answer:
The correct answer is OPTION B (b. Yes—the initial infection might be acute but the virus can later become latent by becoming integrated into the host cell genome).
Explanation:
The hepatitis B virus has an unusual feature similar to retroviruses. This makes it deadly and difficult to treat when it is at an advanced stage. It basically attacks the liver and can cause both an acute and persistent infection.
In the acute stage, the cells are newly attacked and the body is fighting it off, the symptoms might start showing depending on how long it has invaded the body. These symptoms include dark urine, vomiting, yellowing of the skin and eyes (jaundice), the liver can still fail at this stage causing death.
At the persistent stage, which is already chronic, the invaded cells have been weakened, the symptoms are slow to resolve therefore it is in a prolonged stage which can lead to liver cancer and eventual death.
Answer:
Answers in order are:
Male
Cell surface
Shape
Sex attractant
Female
Explanation:
Luna Moths are unique species of organisms owing to their remarkable way of communicating sexual. Female Luna moths attract their male counterparts by releasing minute amounts of sexual pheromones, which is detected by the males using their Long antenna and guides him to the female in order for mating to occur.
Based on this, the complete part of the question is in CAPS:
Receptor cells only on the filaments on the ___MALE__ Luna moth’s antennae contain __CELL SURFACE___ molecules that are complementary in __SHAPE___ to __SEX ATTRACTANT___ molecules (sex attractants) produces by the ___FEMALE__ Luna moth.
Answer:
The four parts of a control system include the controller, amplifier, actuator, and lastly, feedback.
