A The salamanders would have no water to drink.
B The salamanders would have no place to mate and lay their eggs.
The development would have no effect on the salamander population.
C The salamanders would not survive at all if the developer built houses in the woodlot.
I know its B but why would it be B?
B. initiate attacks of rival tribes in order to profit by selling captured Africans to the Europeans.
C. establish peaceful relationships wih the Europeans out of fear.
D. pay the Europeans lots of money to avoid becoming colonized.
The answer is B. Since slavery was introduced to the West Coast of Africa in the 1600s, it became a thriving trade that spurred the industrial revolution. The trans-Atlantic slave trade was used to put slaves on the farms in the Americas. The African leaders benefitted from the sale of Africans as slaves. Powerful kingdoms hence raided weaker tribes to capture slaves for sale to the Europeans.
Answer:
The poles
Explanation:
Because the air is thinner and more sun radiation.
B) gene duplication
C) histone modifications
D) random point mutations
Answer:
A) exon shuffling
Explanation:
Exon shuffling refers to the process of evolution of a new gene that consists of unique combinations of preexisting exons. These novel combinations of preexisting exons are formed when the interspersed repeats of introns of two different genes undergo the process of recombination.
The process of exon reshuffling is responsible for the presence of common domains between two otherwise different proteins of eukaryotes.
Example: Tissue plasminogen activator and epidermal growth factor are very different proteins but share the EGF domain.
O The water would move into the cell and the cell would increase in size.
O The salt would move into the cell and the cell would increase in size.
O The salt would move out of the cell and the cell would decrease in size..​
Answer:
The water would move out of the cell and the cell would decrease in size.
Explanation:
This question is depicting OSMOSIS, which is the movement of water from a region of high concentration (low solute concentration) to a region of low concentration (high solute concentration) across a semi-permeable membrane. This movement is caused when a concentration gradient forms between the two sides of the membrane.
In this case, an animal cell contains an internal salt concentration of 10% while the salt solution has a concentration of 30%. This means that the animal cell is hypotonic (contains high water concentration) to the salt solution, hence, water would move out of the cell and the cell would decrease in size
If an animal cell with an internal salt concentration of 10% is placed in a salt solution with a concentration of 30%, the water would move out of the cell and the cell would decrease in size.
If an animal cell with an internal salt concentration of 10% is placed in a salt solution with a concentration of 30%, the water would move out of the cell due to osmosis. The higher external salt concentration draws the water out of the cell, causing the cell to shrink or decrease in size.

B. radiometric dating
C. photosynthesis
D. respiration
Photosynthesis provided the Earth with an oxygen-rich atmosphere.
Earth's surface environments are highlyoxygenated from the atmosphere to the deepest reaches of the oceans, representing a hallmark of an active photosynthetic biosphere. However, the fundamental timescale of the oxygen-rich atmosphere on Earth remains uncertain, particularly for the distant future.
Scientists estimate that 50-80% of the oxygenproduction on Earth comes from the ocean. The majority of this production is from oceanic plankton drifting plants, algae, and some bacteria that can photosynthesize
