BartSMP [9]3 years ago

The placenta is the interface between the maternal and embryo's blood, and allows for the exchange of nutrients, including oxygen and carbon dioxide exchange, but prevents certain drugs and chemicals from reaching the embryo. Its a bit like a security guard that only lets certain things though to the baby.

Identify the phases of Meiosis II described below.
Annette [7]

1. The lining up of chromosomes by the spindle fibers takes place at metaphase II phase. It is the second stage of meiosis II, the spindle draws the chromosomes towards the metaphase plate.  

2. The formation of the nuclear envelope around each set of DNA takes place in telophase II. Along with the formation of the nuclear envelope, the process of cytokinesis also takes place in telophase II, producing four daughter cells, each comprising a haploid set of chromosomes.  

3. The sister chromatids are pulled apart in anaphase II stage. In this phase, the sister chromatids are migrated towards the opposite poles of the cell with the help of protein fibers.  

4. The centromeres are moved towards the poles of the cell at prophase II stage.

:<br> The correct order of stages in primary succession of a volcanic island is
miskamm [114]

Answer:

Volcanic rock-lichen-mosses-sea grasses

Explanation:

Lichens are complex living beings that form a symbiosis of an organism formed by a fungus and an algae or cyanobacterium. They're known for interacting with volcanic rocks. Moss is a cosmopolitan phylum of small, simple-organized, and non-vascular cryptogamous plants that typically grow in dense tufts, which are more common in humid and dark habitats. They're the ones to come after the lichens during primary succession of volcanic island environments. Marine angiosperms, also known as, sea grasses, are the flower-producing plants adapted to life in seawater that form marine meadows on the euphotic bottoms of the oceans. They install themselves on the coasts that are populated by mosses, therefore not being uncommon to see in volcanic islands.
