<span>If
a geological barrier (like a continent splitting apart) separates a
population of primates, then each population will evolve separately to
fit the different conditions of their environments.
As a hypothetical example, if one part of Pangea went north, the
primates on that part would adapt to cold temperatures. If the other
part went toward the equator, those primates would adapt to heat and
direct sunlight. Eventually they would evolve into different species
over many generations.</span>
Answer:
Explanation:
Amphibians are group of animals that live a double life; one in water with gills and the other on land with lungs (at maturity). They include frogs, newts, salamanders etc.
Reptiles ( meaning to creep under shadow of darkness) are group of animals that possess scales. They include snakes, crocodiles, lizards etc.
Reptiles and amphibians are distantly related but share some traits including:
1. They are both poikilothermic (cold-blooded) animals i.e. their body temperature is dependent on that of the environment's.
2. They both lay eggs externally, although that of amphibians is fertilized after being layed
3. They both possess lungs for gaseous exchange, although, amphibians use gills in water.
4. Both reptiles and amphibians belongs to Chordata i.e. they both possess a vertebrae column (backbone)
5. Most reptiles and amphibians make use of the same defensive and attacking traits as a pretty and predator respectively. They employ camouflage, biting and inflating of their body size.
Answer:
1/2 wWBb , White wool and brown eyes.
1/2 wWbb , White wool and blue eyes.
Explanation:
White wool (W) is dominant over black wool (w).
Brown eyes (B) is dominant over blue eyes (b).
A sheep with black wool (ww) and brown eyes (Bb) is crossed with a sheep with white wool (WW) and blue eyes (bb).
<h3>wwBb x WWbb</h3>
If there is independent assortment between genes, the genotypes of the first parent's gametes will be wB and wb. The gametes of the second parent can only be Wb.
<u>The resulting offspring will be:</u>
- 1/2 wWBb , White wool and brown eyes.
- 1/2 wWbb , White wool and blue eyes.
An example of an dramatic environmental event can be deforestation, or it can be animals losing their homes.
The process of photosynthesis converts light energy into stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen.
