First of all, it needs a deposit of carbon. Then, mass amounts of pressure and heat will be applied to the deposit. Over time, the carbon turns into a crystal which is either burst out of a volcano or remains under the ground.
"Eukaryote" roughly translates as "truly nucleated" and refers to organisms with a membrane-bound nucleus.
Such membrane-bound organelles are thought to have arisen via the invagination of the cell's own plasma membrane.
Other organelles such as the mitochondria and the chloroplast are believed to have once existed as separate organisms, but which were engulfed by other cells, forming a symbiotic relationship.
<span>Traits are determined by proteins that are built according to the instructions stored in the genes.</span>
<h2>Development of Plant Needles</h2>
Explanation:
- Seed of pitch pine treated with colchicine delivered tetraploid seedlings which had thick and sporadic needles and less fortunate tallness and diameter growth than ordinary seedlings.
-
In test of colchicine-initiated polyploidy in pines, researcher found that a significant number of the polyploid plants returned to a diploid development in light of the fact that the polyploid cells partitioned at a more slow rate and were overwhelmed by the more quickly developing diploid cells which encompassed them.
-
The primary needles of both diploid and polyploid plants were more effective at low light intensity than secondary needles, and they had lower compensation points.
Answer & Explanation:
As células sanguíneas são classificadas em três grupos básicos: os leucócitos ou glóbulos brancos, que são células de defesa integrantes do sistema imunitário; as hemácias , glóbulos vermelhos ou eritrócitos, responsáveis pelo transporte de oxigênio; e plaquetas, responsáveis pela coagulação sanguínea.
