Answer:
lichens and bryophytes[secondary seccession]
Explanation:
after the wildfire, the area would bee too dry and therfore it'll lead to a xerarch succession. lichens and bryophytes would be the climax communities.
Answer:
A
Explanation:
when light is limited photosynthesis will be slowed so the euglena will prefer to ingest food...light is needed for photosynthesis
The correct answer of the given question above would be the third option: THE EVOLUTION OF POPULATIONS OVER TIME. What is represented by the base of a phylogenic tree is the evolution of populations over time. It is also known as the evolutionary tree. This tree shows the evolutionary relationships among species.
Answer:
Option a is the one, that is true.
Sister chromatids separate in anaphase of mitosis and anaphase Il of meiosis
Explanation:
After the interphase in the cell division cycle, the mitosis process begins, which is composed of 4 phases, prophase, metaphase, anaphase and telophase. The prophase occurs when the chromatin is condensed and the mitotic spindle is formed, the metaphase the chromosomes align along the cell equator, in the anaphase the separation of the sister chromatids occurs and in the telophase finally the heterochromatin is converted into euchromatin and the envelope is formed nuclear cell.
Meiosis, which is the cell division of germ cells, also has the same phases but they occur on two occasions: prophase I, metaphase I, anaphase I and telophase I for meiosis I and for meiosis II, prophase II, metaphase II, anaphase II and telophase II. In the anaphase I the homologous chromosomes are separated, they are condensed in the prophase II while in anaphase II the chromatids are separated.
Answer:
A
Explanation:
mtDNA is inherited from the mother of a child, this is because mitochondria are in the cytoplasm and the father's gamete (sperm cell) contributes very little or no cytoplasm to the zygote. We know that mitochondrial Eve came from Africa because the mutations in the mtDNA occurred before the <em>out-of-Africa dispersal</em>.
