Adaptation because organisms adapt to avoid extinction.
Answer:
It indicates that core histone genes were present in the last common ancestor of yeasts, plants, and animals
Explanation:
Histones are highly basic proteins that can strongly interact with DNA, which is packaged into nucleosomes, the basic structural and functional unit of chromatin. Each nucleosome is composed of approximately 147 base pairs of DNA wrapped around a core of eight histone proteins (two copies of four types of histones H3, H4, H2A, H2B). These core histones are evolutionarily conserved across eukaryotic kingdoms in terms of sequence and structure. Therefore, DNA-packaging into nucleosomes is considered a constraint for the evolution of core histones. Moreover, the presence of conserved core histones in eukaryotic kingdoms (e.g., yeast, plant, and animal kingdoms) is strong evidence that histone-mediated DNA packaging was presumably present in the last common ancestor of eukaryotic genomes.
We set up an experiment where the same species of plant is grown in boxes covered with plastic that only allows a single color of light through. In which box would we expect the least plant growth and even perhaps the death of the plant to occur?
Answer:green
Answer:
hi here is your answer hope it helps
Explanation:
The hypothesis of microspheres builds off of the RNA world hypothesis. If RNA molecules could self-replicate, it would mean that whenever a microsphere split, the early genetic coding in the RNA would pass to the newly formed microspheres.
The answer is Keystone. Keystone is a species in which others species in the ecosystem largely depend on, if the species was removed the ecosystem would change drastically.
