Answer:
Structure in a chromosome that holds together the two chromatids
Explanation:
The existence of being able to process photosynthesis.
Photosynthesis is a functional and adaptive mechanism which enables plants to make and create their own food with the use of sunlight. Also, water and carbon dioxide, oxygen is then the by product of this process which is beneficial to other organisms especially heterotrophs.
Answer:
1) Binds soil particles into aggregates and improves the water holding capacity of soil.
2) When carbon dioxide dissolves in seawater, most of it becomes bicarbonate ions and hydrogen ions. This increase in hydrogen ions is what decreases the pH.
3) Carbon dioxide (CO2) and other greenhouse gases act like a blanket, absorbing IR radiation and preventing it from escaping into outer space. The net effect is the gradual heating of Earth's atmosphere and surface, a process known as global warming.
Without greenhouse gases in its atmosphere , the Earth would be much colder on average than it is now. Greenhouse gases: absorb energy transferred as infrared radiation from the Earth's surface. release infrared radiation in all directions, which keeps the Earth warm.
Explanation:
Answer:
Pyramidal decussation is at the junction of medulla and spinal cord.
Explanation:
Pyramidal decussation may be defined as the the fibers that cross the corticospinal tract from one side to the junction and the other side to the central nervous system.
Pyramidal decussation is the point at the junction between spinal cord and medulla. The motor fibers crosses the midline from the medullary pyramids.
