It is a true statement that <span>David buss, an evolutionary theorist, has attributed the big five personality traits to evolved ancestral needs. The correct option among all the options that are given in the question is the first option. I hope that this is the answer that has actually come to your desired help.</span>
Answer:
1. Number of DNA molecules after 30 Cycles of PCR = 1.02 x 10^9
2. No. of mutant DNA molecules = 1.07 x 10^9
Explanation:
1. You just have to take the exponential of 2 to the power of the number of PCR cycles (2^n)
2. All copies were normal at cycle 10 that are about 1024 copies. At cycle 11 single point error, all further copies are mutated.
<h2>Sodium channels </h2>
Explanation:
Depolarization is a result of sodium channels opening as a result of chemical or pressure-based stimuli
- Depolarization starts when a threshold stimulus applied on a neuron via Na+ mechanically operated channels that trigger action potential
- Action potential is an efficient signaling process by which distantly located cells communicate to each other
- Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
- Fast opening of voltage gated Na+ channel shifts membrane potential from -70mV to + 50mV at which voltage gated Na+ channels become inactive thus influx of Na+ abruptly stops
1. plants do not need and complex excretory organ because it creates a very small amount or nitrogenous waste.
Answer: It should be D.
Explanation
Facilitated- requires energy- large molecules require energy to go cross the phospholipid bilayer.
