Correct Answer: In the adult heart, blood in the right chambers of the heart cannot enter the left chambers without passing through the lungs.
Explanation:
In the adult heart, blood in the right chambers of the heart cannot enter the left chambers without passing through the lungs is correct regarding mammalian heart.
Correct Answer: prostate
Correct Answer: Sac formation
Explanation:
Ascomycota is a division or phylum of the kingdom Fungi that, together with the Basidiomycota, form the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes.
Hence, Sac formation is a characteristic of the Ascomycota fungi.
Correct Answer: It is about 90% water.
Explanation:
The first option is incorrect because it is devoid of blood cell, also red blood cells so doesn?t contains haemoglobin.
The second option is incorrect because plasma is colorless.
The third option is also incorrect because plasma contains the clotting factors.
Correct Answer: Protects lungs
Explanation:
When you breathe in air through your nose, it contains lots of tiny things, like dust, dirt, germs, and pollen.
The air enters our body through the nose. However, before it enters the lungs, it must be heated and purified. Many dust particles that enter along with the air are removed in the nose by mucus and thus it protects lungs.
Correct Answer: pleura
Explanation:
The pleura is the membrane that covers the lungs, according to InnerBody. The pleura consists of two layers, with the parietal pleura forming the membrane's outer layer and the visceral pleura forming the membrane's inner layer.
Correct Answer: Vertebral column
Explanation:
The axial skeleton is the part of the skeleton that consists of the bones of the head and trunk of a vertebrate. In the human skeleton, it consists of 80 bones and is composed of six parts; the skull bones, the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column.
Bones of shoulder, thigh and foot are the part of appendicular skeleton.
Hence, Vertebral column is the part of axial skeleton.
Correct Answer: TRUE
Correct Answer: synthesis of DNA from an RNA template
Explanation:
A reverse transcriptase (RT) is an enzyme used to generate complementary DNA (cDNA) from an RNA template by a process called Reverse Transcription.
In brief its function is that copies all or part of the virus RNA (retroviruses are RNA-only) as DNA which can then be integrated into the DNA of the host organism.
Correct Answer: Mitochondria
Explanation:
Cellular respiration is the multi-step process that creates energy from nutrients and food molecules. It begins in the cytoplasm of the cell, with the mitochondria functioning as the main organelle where the rest of the process continues and finishes.
During respiration, glycolysis occurs in the cytoplasm of the cell.
