Biology
1 answer:
nekit [7.7K]3 years ago
8 0

Answer:

The correct answer is - A. Tight DNA packing tends to promote gene expression.

Explanation:

Euchromatin which is less packed or condensed is highly expressed as it participates in the transcription whereas highly compacted chromatin - heterochromatin not expressed at all as these does undergoes the transcription process.

DNA binds around a core of 8 subunits of Histone protein in a nucleosome in which DNA is negatively charged and histone protein is positively charged protein .

DNA packing decreases its transcription and hence no expression.

aivan3 [116]

Answer:

The percentage (%) of the alleles that code for this trait in the population will increase, as more individuals are born with the trait.

Explanation:

The more individuals get born expressing the trait, the higher its frequency gets in the population. By generation, there are more individuals carrying the allele for the advantageous trait. These individuals reproduce and increase the probabilities of the progeny to inherit the mentioned allele. When this sequence keeps occurring in the population over many generations, the allele percentage will increase. On the other hand, the other allele or alleles will decrease. Probably, if there are no changes that might influence or affect this pattern, the alleles for the advantageous trait will fixate, while the other allele might get lost.

1) The male frogs croak to attract mates. They can also visually attract females by displaying vibrant colors. They compete by comparing who calls louder

2) This aids in survival because this ensures that only healthy frogs get to pass down their genes. Unhealthy frogs will not be selected by females. This is called sexual dimorphism

3) The hummingbird displays its impressive tails which they move around to attract females. They may perform aggressive movements against other competing males.

4) These strategies are very important to maintain a diverse and healthy population in a community of animals.
