Answer:
A
Explanation:
Asexual reproduction is a type of reproduction where offspring comes from a single parent.
B is incorrect because asexual reproduction requires only one individual, while sexual reproduction requires two.
C is incorrect because mutation rates are not lower in sexual reproduction than in asexual reproduction.
D is incorrect because lots of single-celled organisms, like bacteria, reproduce asexually.
Answer:
mine to but i have no idea about that what grade are u in thats kinda hard and comfusing.
Explanation:
B is the correct energy because carbs contain lots of energy
Answer:
In order to perceive a stimulus, that stimulus has to meet or exceed the absolute threshold; in order to detect a change in that stimulus, the stimulus has to meet or exceed the differential threshold.
Explanation:
The absolute threshold is the minimum intensity of energy that is required to cause a sensation in a person, that is, the minimum or maximum maginitude that a stimulus must have in order to be captured. The absolute threshold defines our perceptual limits and varies depending on the individual. The differential threshold (Just Noticeable Difference, JND) refers to the minimum intensity at which a stimulus must be increased so that we notice a change in that stimulus, that is, it's the increase that is necessary in the intensity of the stimulus so that the person perceives a modification of the same.
Weber's law states that the stronger the initial stimulus, the greater is the additional intensity necessary for the second stimulus to be perceived as different.
Answer:
Three theoretical models for the replication of DNA had been proposed in the past. Out of these, the method of semi-conservative replication is most widely accepted.
Conservative replication: In this method, no DNA unwinding takes place. The parent DNA gives rise to daughter DNA.
Dispersive Method: In this method, the chains in the DNA molecule break and recombination occurs randomly. The daughter and parent strands will have segments of recombinant DNA.
Semi- conservative: In this method, the two strands of the double helix unwind. Each strand acts as a template for the synthesis of a new strand.
DNA replication is more complex in eukaryotes as compared to prokaryotes. Prokaryotes have a single point of origin from where the replication begins. Eukaryotes have multiple points of origin. Eukaryotic cells have a unidirectional method of replication whereas prokaryotes do not. Prokaryotes just have two polymerases whereas eukaryotes have more than four. The replication rate is faster in prokaryotes.
