Answer:
water density
Explanation:
These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.

Answer:
d) genetic characteristics such as ribosomal RNA sequences
Explanation:
Carl Woese and his collaborators identified two major branches of prokaryotic evolution which are bacteria and archaea. They used 16S rRNA sequencing to study the similarities and differences between archaea and bacteria.
After sequencing the complete genome structure of Methanococcus jannaschii in 1966 which is an archaea they concluded that bacteria are more closely related than humans than bacteria.
After many years Carl Woese gave the three-domain system which divides prokaryotes into archaea and bacteria according to differences in their rRNA sequencing. Eukarya was the third domain. So the correct answer is d.
The correct answer or option is cerebrum
The cerebrum, also called cortex is the largest part of the brain.
It is divided into four sections, called lobes and these are the frontal lobe,
the parietal lobe, occipital lobe and temporal lobe.
Front lobe helps in speech, reasoning, planning, movement ,
emotions and problem solving.
parietal lobe helps in orientation, and perception of stimuli and
movement.
Occipital lobe helps in visual processing.
Temporal lobe helps in memory, speech as well as perception and
recognition of auditory stimuli
The human population has grown more and more quickly over time since the development of agriculture.
Option (a);
<u>EXPLANATION:</u>
- The growth in agriculture allowed an increase in population over time.
- Agriculture developed with more irrigation facilities and farming machines.
- So, more food could be grown and was available round the year for the
- people to consume.
- With urbanization, food could be transported well across the places.
- A smaller number of people died due to starvation. People settled in towns and cities to do farming.
- Thus, with the overall development of agriculture eventually, health and nutrition improved which led to an increase in population.
