Answer:
2 main lobes
Explanation:
The liver holds about one pint (13%) of the body's blood supply at any given moment. The liver consists of 2 main lobes. Both are made up of 8 segments that consist of 1,000 lobules (small lobes). These lobules are connected to small ducts (tubes) that connect with larger ducts to form the common hepatic duct. The common hepatic duct transports the bile made by the liver cells to the gallbladder and duodenum (the first part of the small intestine) via the common bile duct.
Answer:
d. transcriptional regulation (regulation of whether transcription occurs)
Explanation:
If the product of a gene is not needed, then allowing the transcription of such gene to proceed only to be regulated after or even after translation will result in a mere wastage of resources. It thus means that the resources utilized for transcription has been wasted.
<em>Hence, the correct option is d.</em>
B.when the eye reaches the land mass
Answer
1. The vascular and dermal tissues
2. Protein capsid
Explanation
Dermal tissue present in plants offer the first defense mechanism against physical damage which could be caused by insects and infections.The dermal tissue covers the outside parts of a plant except in woody shrubs and tree which are protected by the bark. Vascular tissues in plants are responsible for the transportation of water and nutrients that are vital in cell repair and growth.Through vascular tissues, the plant obtains nutrients important for the restoration of the damaged cells.
A capsid is the protein shell of a virus.It is composed of protomers which are subunits.Some viruses are enveloped by a capsid coated with a lipid membrane called the viral envelop.The main function of a capsid is to protect the genetic material of a virus while interacting with the host environment.
