Answer:
- T. Natural Reseeding.
- D. Species Diversity
- A. Ecosystem Diversity.
Explanation:
Natural reseeding uses natural elements and actors to plant the seeds of trees. These elements and actors include water, wind, birds, rodents and other actors capable of scattering seed.
Species diversity is what defines the differentiation between the different species in an ecosystem and Ecosystem diversity relates to how biological communities/ ecosystems can be different from each other based on the organisms and food chains available in each.
Answer:
It has incomparable advantages over other gene editing tools.
Explanation:
For example, the CRISPR-Cas9 system has more target sites than ZFNs and TALENs, and Cas9 has many variants that can be used in a variety of studies. Moreover, the system is extremely easy to use and can be executed in almost any laboratory.
The most important advantages of CRISPR/Cas9 over other genome editing technologies is its simplicity and efficiency. Since it can be applied directly in embryo, CRISPR/Cas9 reduces the time required to modify target genes compared to gene targeting technologies based on the use of embryonic stem (ES) cells.
Disadvantages of CRISPR technology: CRISPR-Cas9 off-target; The effect of off-target can alter the function of a gene and may result in genomic instability, hindering it prospective and application in clinical procedure.
this the best i got, hope it helps :)
The goal was to see if Earth's ecosystems could be successfully manufactured and maintained elsewhere in the galaxy, should we need to bail on this planet.
It was named Biosphere 2 because it was meant to be the second fully self-sufficient biosphere, after the Earth itself
Explanation:
The length of the sperm in a few species is much larger or giant than the size of the animal-like observed in the <em>Drosophila bifurca.
</em>
In this fruit-fly, the tails of the sperm are too long which could be accounted for many reasons:
1. The sexual selection prefers the long tails over the small tail.
2. The large sperms can displace the small sperms in the female reproductive organ.
3. The female reproductive organ increases the promiscuity of the large sperms that is favour the large sperms over the small sperms.
