The question is asking to states on how i earth's early lang environment different than today's land environment and base on my research, I would say that in the past centuries or early ages, the Earth's land environment are compost of tree and plants and the air is still fresh. I hope you are satisfied with my answer and feel free too ask for more
Answer:
nucleolus
Explanation:
The nucleus contains the cell 's DNA and directs the synthesis of ribosomes and proteins. Found within the nucleoplasm, the nucleolus is a condensed region of chromatin where ribosome synthesis occurs.
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 answer is <span>D. The Plasmodium life cycle would be interrupted, and the infection could not be passed on.
Mosquitoes are necessary for malaria infection. According to the lyfe cycle, after infected mosquitoes bite a human, they inject saliva with sporozoites into the human circulatory system (stage A). The sporozoites enter human liver where they divide and schizonts are created. Schizonts give birth to merozoites (stage B). Merozoites are released into the bloodstream where invade red blood cells (stage C). Inside the red blood cells, they evolve into trophozoites, they into erythrocytic schizonts, and finally into a new generation of merozoites (stage D). After the red blood cells rupture, they are released into the blood stream (stage E). Therefore, if mosquitoes disappear, the first stage (stage A) will be missing, so the plasmodium life cycle will be interrupted.</span>
When a campfire is left unattended, and a forest fire breaks out can eventually result in secondary succession.
Explanation:
Secondary succession refers to the succession process in which an area which was previously colonized is disrupted and gets re-colonized.
Secondary succession often is associated with major disturbing events such as fire, flood, epidemic after which a new set of species dominate the region. Abandoned farms, vacant lands can also undergo succession when relatively resistant species of plants can dominate the land following the extinction of the pioneer species.
Forest fire plays a major role in secondary succession by initiating it. Forest fires raze every pre-existing plant to the ground and lay the vacant ground ready for colonization by new species.
