I'm pretty sire the answer to this would be
c. <span>add new genes to the gene pool </span>
Answer:
46 chromosomes
92 Chromatids
One DNA molecule
Explanation:
The interphase part of the cell cycle is divided into 3 sub-phases namely; G1 phase, S-phase and G2-phase
G2-Phase occurs when the cell grows more to make more proteins and organelles. This also when the cell reorganize its contents in preparation for mitosis. The number of chromosomes will therefore, remain the same but the DNA molecule will be one in preparation for mitosis where it can then divide into two
Answer:- Surface is primarily driven by wind (friction from wind transfers energy and momentum to surface water)
- Deep is slower, driven primarily by density (salinity and temperature) differences
- Thermocline: dramatic temp drop 50 m from surface bc sun can't shine
- Halocline: dramatic gradient in saline, increase as it deepens
- Pycnocline: resulting change in density (50-1000)
Explanation:
A reduction in sea ice due to climate change has negatively affected the food abundance of Penguins.
Explanation:
- Sea ice is ocean water frozen blocks. Unfortunately, rather than most other areas, climate change impacts Antarctica.
- If the temperatures on the surface of air and water rise, the sea ice melts. This leads to many marine mammals and seabirds losing their habitat and food supply, including Adelie penguins.
- The biggest threat to the penguins stems from changes in the Antarctic sea-ice cover, that will affect its feeding and breeding.
