Answer:
Microtubules play an important role in cell division by contributing to the formation of the mitotic spindle, which plays a part in the migration of duplicated chromosomes during anaphase.
Answer:
First, you need to retrieve the FASTA sequences of the already sequenced genes. After that, you should make a sequence alignment on a software like CLUSTALW (https://www.ebi.ac.uk/Tools/msa/clustalw2/) to seek for the conserved regions of the gene. Based on this regions, you will design your FISH probe, which for bacteria can start in 33 bp (Ming Tan <em>et al.</em>, 2019), but a 200 bp probe is a very suitable size. There are several companies that fabricates this custom probes, and sell all the reagents to perform the experiments. Having this, you will perform your FISH experiment to see which cells are actively degrading Toluene.
Explanation:
The Collective Set of Alleles in a Population Is Its Gene Pool. The fact that genes exist in alternate forms, called alleles, forms the basis for the study of population genetics.
(I believe this is the correct answer)
Missing options:
A) Nerodia spedon and Nerodia fasciata
B) Eudocimus albus and Ardea albus
C) Egretta thula and Platalea ajaja
D) Pituphis melanoleucus and Thamnophis proximus
Answer:
A) Nerodia spedon and Nerodia fasciata
Explanation:
Phylogenetically, the closer relatives share same ancestor and therefore same clad in phylogenetic tree. In the given options, Nerodia spedon and Nerodia fasciata share same genus name so they are closer relatives. If we go further about their characteristics, they are two types of water snakes that are found in north and south America. They both are also non-venomous.
On the other hand, remaining options are not correct because none of the mentioned organisms share same genus name and belong to different positions in the phylogenetic tree.
The right answer is: Plant growth would decrease.
Decomposers are living beings directly involved in the decomposition of dead organic matter (necromass) or excrement or excreta of living beings. They play a major role, necessary for the recycling of the elements (minerals, trace elements ...) that make up the organic matter, in an inorganic matter which will subsequently be absorbed by the plants (which explains the decrease of the growth of the plants during the absence of decomposers).
