How do histones and nucleosomes affect DNA?

Biology

forsale [732]3 years ago

In biology, histones are highly alkaline proteins found in eukaryotic cell nuclei that package and order the DNA into structural units called nucleosomes. They are the chief protein components of chromatin, acting as spools around which DNA winds, and playing a role in gene regulation.

How do materials move within the earth.
statuscvo [17]

The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

<h3>How do materials move within the earth?</h3>

The Earth's thermal energy is the main cause of the movement of materials within the earth surface. The Large continent-size plates moves slowly about the Earth's surface, which is driven by the thermal energy. The Convection currents transfer hot, buoyant magma to the lithosphere's layer at plate boundaries and hot spots. Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.

So we can conclude that: The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

Which species will most likely survive if earth temperature increase?
joja [24]

It's for sure not A because having thick fur will only make you hotter, and thus you will suffer a heat stroke. It's not C because small ears would not be long enough to provide you with cooling. That one does not make sense. It could be D, but the species would need to have alot of muscles in order to be consistently flapping there ears for the constant hear. Answer is B because it is the most logic, and the fewer amount of fur, the less hotter you will be, especially if your fur provides insulation.

Answer is B. Species B because fur would provide insulation.

identify a probable reason that the dark moths survived while the light moths did not during the industrial revolution
nignag [31]

Answer:

directional selection

Explanation:

The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. <em>Biston betularia</em>, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.
