(a current in a fluid that results from convection.)

Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth’s ocean currents, atmospheric weather and geology. Convection is different from conduction, which is a transfer of heat between substances in direct contact with each other.

A doctor is studying a disease where the nucleus of a cell does not grow properly. What do you think would happen to the cells'
Drupady [299]

Answer:

The cell would fail to function. It would likely fail to properly replicate DNA properly or transcribe genes.

Explanation:

The nucleus holds the genetic information, the DNA. If the nucleus does not grow properly, the DNA might not fit or be properly organized inside. This would mean DNA replication could not proceed as normal, and the DNA might not even be able to fit inside the nucleus!

The cell would also struggle to properly transcribe the DNA if the nucleus is not fully formed. DNA acts as a template for mRNA transcription, which directs protein synthesis. The cell will very quickly die if there are inaccuracies in protein synthesis due to mRNA not being adequately synthesized.
