Answer:Physical systems differ from social systems because a physical system refers to systems that rely on a group of physical parts to perform a function. Examples of a physical systems are solar systems or even an animals digestive system. Social systems are systems like an ant colony, wolf pack, or a town.
Explanation:
Answer
After inland population after migration allele frequency is 0.62 or 62%
Explanation:
Given,
Coastal striped phenotype freq. = 0.22
ss = 0.22
= 0.22
Similarly, inland striped phenotype freq. = 0.43
= 0.43
= 
= 0.4690
= 0.47 i.e. 47%
= 0.655
= 0.66 i.e. 66%
the migration range (m) is given as 20%
m= 0.2
allele freq. after migration = pre migration + ∆q
here,
∆q = change in the allele frequency
or
migration of allele freq. from coastal to inland
=
= 0.2 (0.47 – 0.66)
=
= - 0.0382
∆q = -0.04 i.e. 4%
Answer:
1 2 and 3
Explanation:
Because it is like a food chain without the bacteria or woms many animals would be out of food.
Explanation:
mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.
Answer: It depends on the resources available and abiotic factors such as quantity of light, water, range of temperatures, and soil composition
