They're attached to the plasma membrane.
(it's at the midpoint of the cell.)
Habitat loss is contributing to the permanent loss of species, the weakening of ecosystems, and is impacting the overall health of the planet.
Example:
While tree-clearing is a significant cause of habitat loss in Australia, other major contributing factors include altered bushfire frequency and the introduction of pest species that make habitats unsafe for native species or outcompete them. Meanwhile, on the Great Barrier Reef, the impacts of human-induced climate change are altering the habitats of corals, leading to large-scale coral bleaching. Over time, destruction of such habitats leads to reduced biodiversity and weakening of the Earth’s ecosystem.
In multicellular plants and animals, however, meiosis is restricted to the germ cells, where it is key to sexual reproduction. Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).
The process of development of a seed into a new plant is also called the germination process.while the pollination is the process of seed dispersion.
Germination occur in favourable conditions including environmental condition like how deep seed is planted, water availability,sunlight and temperature
Answer:
A) A transgene integrated into a heterochromatic region of the genome.
Explanation:
This is most likely the reason why the transgene is not expressed in the fifth cell line. It is likely that the transgene was integrated into a heterochromatic region of the genome. Heterochromatin consists of genetically inactive satellite sequences, and many of these are repressed to various extents. Moreover, because this is a tightly packed form of DNA or condensed DNA, it is inaccesible to polymerases and thus not transcribed.
