Biology
1 answer:
Andreas93 [3]3 years ago
4 0

Answer:

False

Explanation:

Scientist believe that the primitive atmosphere lacked free oxygen. Oxygen is a highly reactive molecule that would have made difficult for complex macromolecules to appear and then create life.  Rocks from the precambrian period support this theory.

Anaerobic cells appeared first, then photosynthesis appeared filling the atmosphere with oxygen and the aerobic organism develop cellular respiration to obtain energy, a process more efficient than anaerobic respiration.

How do the nervous system and endocrine system differ in regards to managing homeostasis?
Citrus2011 [14]
Hello friend!!
The biggest difference between the two is that the nervous system uses electrical impulses to send signals through neurons, whereas the hormonal system uses chemical messengers transported into blood plasma to target cells. 
Transmission by the nervous system is short-lived but quick, whereas transmission by the hormonal system is long-lasting but takes much longer. Hene, communication is faster when using the nervous system. 
In the nervous system, responses are localised - whereas in the hormonal system, they are widespread. Responses are often permanent in the hormonal system, but temporary and reversible in the nervous system.

Anaphase I
Homologous chrmosomes move to the oppisite poles of the cell.


Telophase I and Cytokinesis
Chromosomes gather at the poles of the cells & the cytoplasm divides.

Prophase II
A new spidle forms around the chromosomes.

Metaphase II
Chromosomes line up at the equator.

Anaphase II
Centromeres divides & chromatids move to the opposite poles of the cells.
