Answer:
La cromatina
Explanation:
La cromatina es una sustancia dentro de un cromosoma que consta de ADN y proteína. El ADN lleva las instrucciones genéticas de la célula. Las principales proteínas de la cromatina son las histonas, que ayudan a empaquetar el ADN en una forma compacta que encaja en el núcleo celular.
La cromatina es un complejo altamente organizado de ADN y proteínas y es un componente principal del núcleo celular. Las proteínas histonas ayudan a organizar el ADN en unidades estructurales llamadas nucleosomas, que luego se ensamblan en una estructura compacta (cromatina) y, finalmente, en estructuras muy grandes de orden superior (cromosomas).
Answer:
True
Explanation:
Milipedes belong to a class of organism known as diplopoda which have double foot. Thus, millipedes have two legs per segments. They usually have two pairs of jointed legs. The double legged segments have formed out of two single segments fused together
On the other hand , a centipedes has only one pair of legs per segment.
Thus the given statement is true.
The correct answer is - nitrogen and phosphorus.
The nitrogen and the phosphorus are the two substances that cause most of the eutrophication. It is good for the organisms that live in the water when these two substances are available as they are very important nutrients, but if the optimal amount is surpassed than it can be devastating. When there's high quantities of nitrogen and phosphorus in the water it makes it much more rich in nutrients that it should be. That kind of situation is the best for the algae, which start growing all over the place, quickly covering the water and becoming the dominant life form. As that happens, the organisms that use photosynthesis will die out because the Sun will be blocked, and the algae will also contribute to a big reduction of the oxygen in the water too. The end result being totally destroyed ecosystem that has been overtaken by algae.
. DNA replication is a highly accurate process, but mistakes can occasionally occur as when a DNA polymerase inserts a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer. ... Mutations: In this interactive, you can “edit” a DNA strand and cause a mutation.
