There is no picture of the bird.
answer: country grasslands, African trees, and African Savannah.
or just like more dry lands.
The given statement "wilderness ecosystems are dynamic, complex, and often fragile, and may be impacted by human use and activities occurring both within and outside wilderness boundaries," is true.
Wilderness ecosystems
The wilderness ecosystem is the ecosystem that has been left undisturbed by humans. There are many areas on the planet that are considered wilderness such as the Great Barrier Reef, the Amazon forest, etc. They are rich in both flora and fauna diversity.
In the United States, a total of 42×
ha is under the protection of the National Wilderness Prevention System. They are the lands devoted to the protection of the natural ecosystem. Such an arrangement had to be made due to human encroachment and various other factors that affect the wilderness ecosystem. The main threats to the wilderness ecosystem are
- Using the land for recreational uses
- Grazing by livestock
- Forest fire
- Pollution
- Global warming
- Invasion of alien species
- The unnatural flow of water due to diversions, dams, impoundments, etc.

Answer: gaps left at the 5' end of the lagging strand.
Explanation:
Eukaryotic Chromosomes are known as the repetitive at the very ends of chromosomes, found in a wide range of Eukaryotic species. They protect the end chromosomes from deterioration or fusion with the neighboring chromosomes.
Telomeres provide a mechanism for their replication by semi conservative DNA replication (a replication in which two parental DNA strands would act as a template for new DNA strands to be synthesized) and length maintenance by Telomerase Enzymes. Telomerase Enzymes are used to extend shortened telomeres during its’ DNA replication.
DNA replication in Eukaryotic Telomeres doesn’t begins at the either end of the DNA strands but starts in the center, and considering that all known DNA Polymerase ( an enzyme that is essential for DNA replication) read the template strand in the 3’ to 5’ direction, one finds a leading strand and a lagging strand on the DNA molecule being replicated.
On the leading strand, DNA Polymerase make complementary DNA strand without any difficulty because it reads the template strand from 3’ to 5’.
On the other hand, there is a difficulty going in the other direction on the lagging strand.
WHY? This is “due to gaps left at the 5’ end of the lagging strand”. To overcome this difficulty, short sequences of RNA acting as Primers (a short single-stranded nucleic acid utilized by all living organisms in the initiation of DNA synthesis) attach to the lagging strand, a short distance ahead of where the initiation site was.
I hope this helps alot!
The question does not give any options, I found the excercise on the web and here are the options:
a. Methicillin-resistant Staphylococcus au-reus
b. Neisseria meningitidis
c. Pseudomonas aeruginosa
d. Streptococcus pyogenes
<span>e. Treponema pallidum
</span>
The correct choices are: <span>B, D, E</span>
Penicillin G is the primary medication of choice for N. meningitidis. It is a medication of first choice for contaminations caused by sensitive gram-positive cocci, including S. pyogenes. It is a medication of choice for T. pallidum. It isn't powerful against methicillin-resistant S. aureus or P. aeruginosa.
