A thin, moist, selectively, permeable membrane.
Pan represents the genus while paniscus represents the species.
Answer:
All of the options supplied describe the reasons for the extinction of dinosaurs and other species over 65m years ago.
Explanation:
When an impact event happens, the enormous kinetic energy of the asteroid or meteorite – a massive body travelling at high speed – is partly transferred to the Earth but largely converted into heat and sound, creating pressure waves travelling radially outwards from its centre, similar to that of an atom bomb.
As well as this blast created on impact, large amounts of dust can be kicked up into the atmosphere – like a nuclear winter – blocking out sunlight and preventing plants from photosynthesising, which has a knock-on effect to much of the rest of the ecosystem.
Answer:
S Phase
Explanation:
The synthesis phase of interphase takes the longest because of the complexity of the genetic material being duplicated. Throughout interphase, nuclear DNA remains in a semi-condensed chromatin configuration. In the S phase, DNA replication results in the formation of identical pairs of DNA molecules, sister chromatids, that are firmly attached to the centromeric region. The centrosome is duplicated during the S phase. The two centrosomes will give rise to the mitotic spindle, the apparatus that orchestrates the movement of chromosomes during mitosis. At the center of each animal cell, the centrosomes of animal cells are associated with a pair of rod-like objects, the centrioles, which are at right angles to each other. Centrioles help organize cell division. Centrioles are not present in the centrosomes of other eukaryotic species, such as plants and most fungi.
Answer:
A (The melting of ice in the polar regions)
Explanation:
Global warming creates many effects, which include ice melting way before it should. Sea levels have also risen in the past years which supports the fact of ice melting.
