Answer:
Since every person inherited DNA from their parents, who inherited it from their parents, and so on, a person's DNA is made up of the DNA of their ancestors. If you and another person both have the same ancestor, there's a chance that you both inherited some of the same DNA.

Answer:
1000 mM
Explanation:
Using V = -60 mV㏒₁₀[K/K'] where V = membrane potential = -60 mV, K = intracellular concentration = unknown and K' = extracellular concentration = 100 mM
So, V = -60 mV㏒₁₀[K/K']
-60 mV = -60 mV㏒₁₀[K/K']
dividing both sides by -60mV, we have
-60 mV/-60 mV = ㏒₁₀[K/K']
㏒₁₀[K/K'] = 1
taking antilogarithm of both sides, we have
[K/K'] = 10¹
multiplying both sides by K', we have
K = 10K'
K = 10 × 100 mM
K = 1000 mM
So, the intracellular Cl- concentration is 1000 mM
Answer:
A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem.
The type of control is described by the response of the operon when no regulatory protein is extant. In the case of negative regulator, the genes in the operon are distinct unless they are switched off by a repressor protein. Therefore the operon will be turned on essential (the genes will be prcise) when the repressor in inactived. In the case of positive control, the genes are distinct only when an active regulator protein, an activator, is present, Thus the operon will be turned off when the positive regulatory protein is missing or inactivated.
