The extinction vortex represents the idea that even if an organism is extant, it may have a gene pool that will not support its long-term survival.A. TrueB. False
Answer:
True.
Explanation:
Extinction vortex is a model used by scientists to understand extinction dynamics within a community. This model allows scientists to assess and understand how a population can become highly vulnerable to elements of its habitat, becoming increasingly apt for extinction. According to this model, any organism is capable of extinction, as all are susceptible to having a gene pool that will not allow its survival, regardless of the environment.
At a birthday party, a teen decides to inhale some of the helium from a nearby balloon using his mouth. Before the helium gas reaches his right and left lungs, through which order of structures will it flow?
A. Oral cavity to the oropharynx to the trachea to the right and left main bronchi.
B. Oral cavity to the trachea to the trachea to the nasopharynx to the right and left main bronchi.
C. Oral cavity to the right and left main bronchi to the trachea to the oropharynx.
D. Oral cavity to the trachea to the larynx to the right and left main bronchi.
E. Oral cavity to the nasopharynx to the trachea to the right and left main bronchi.
Answer:
D. Oral cavity to the trachea to the larynx to the right and left main bronchi.
Explanation:
The respiratory system may be a system consisting of specific organs and structures used for gas exchange in animals and plants.
What is the process of respiration?We have a pair of external nostrils opening out above the upper lips. It results in a nasal chamber through the nasal passage. The nasal chamber opens into the pharynx, some of which are the common passage for food and air. The pharynx opens through the larynx region into the trachea.Trachea is a straight tube extending up to the mid-thoracic cavity, which divides at the extent of the 5th thoracic vertebra into a right and left primary bronchi. Each terminal bronchiole gives rise to a variety of very thin, irregular-walled, and vascularized bag-like structures called alveoli. The branching network of bronchi, bronchioles, and alveoli comprise the lung.
Thus, we can conclude that the correct option is (e).
The oral cavity to the nasopharynx to the trachea to the right and left main bronchi.

Enter the sequence of the DNA coding strand with a 5-3 polarity. DO NOT WRITE 5 OR 3 OR 5' OR 3' IN THE BOX!
Complete question:
Use the sequence below to answer the following questions
3’-ACGGATCCTCCCTAGTGCGTAATACG-5’
5’-TGCCTAGGAGGGATCACGCATTATGC-3’
1. Enter the sequence of the coding strand with a 5’-3’ polarity
Answer:
coding strand → 5´- GCATAATGCGTGATCCCTAGGCA -3´
Explanation:
When referring to the coding strand, we are talking about the sequence that turns to be the same as the mRNA that results from the transcription of the same DNI segment -switching bases T for U-.
The coding strand receives that name because it is the sequence that codes for each amino acid composing the proteins.
When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand.
The coding strand goes in direction 5´ to 3´, while the complementary strand -template strand- grows in direction 3´ to 5´.
Whenever we have a DNI molecule and we need to determine which strand is the coding one, we just need to look for the presence/absence of start or stop codons.
So, in the exposed example we have two strands, but we do not know yet which one is the coding one.
Conventionally, the first strand is always the coding one. However, let us analyze it by using the presence/absence of codons.
First-strand:
3’-ACGGATCCTCCCTAGTGCGTAATACG-5’
let us write it is 5´to 3´direction
5´- GCATAATGCGTGATCCCTAGGCA -3´
now let us identify the start and stop codons in 5´⇒3´direction.
Start codon ⇒ ATGStop codon ⇒ TAA, TAG, TGA5´- GCATAATGCGTGATCCCTAGGCA -3´ ⇒ 1 start codon at the beginning
5´- GCATAATGCGTGATCCCTAGGCA -3´ ⇒ 3 Stop codons
Second strand: We will do exactly the same procedure
5’-TGCCTAGGAGGGATCACGCATTATGC-3’⇒ 1 start codon near the end
5’-TGCCTAGGAGGGATCACGCATTATGC-3’⇒ 1 stop codon at the beginning
What we did here was to identify in both provided strands, where the start and stop codons are placed. We can see that in the first strand we have the start codon near the beginning, while in the second strand we have it near the end of the sequence. From this information, we can assume that the first strand is the coding one. However, you need to know that some coding sequences do not have start and stop sequences, because they might correspond to a sequence in the middle of a gene.
So, the sequence of the DNA coding strand with a 5-3 polarity is
5´- GCATAATGCGTGATCCCTAGGCA -3´

Should we clone animals that are going or have gone extinct (in other words bring them back
either from the brink of extinction or from extinction)? Explain your answer.
Answer:
I think we should but people are preventing this though
Explanation:
I think we should because it might benefit the world and let scientists to discover this animal. But then I don't think so because animals that are/were extinct could perhaps be from climate change. Nowadays, people don't take this matter seriously causing habitats to be destroyed and animals to be extinct :) Like icebergs are melting that mean penguins are at risk of being extinct,if we did something then this situation will be prevented. However dinosaurs did become extinct and they did not come back so its probably just life and this is how god planned it:)

Answer:
The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of melatonin.
Explanation:
Melatonin is a hormone produced naturally by the body. Its function is to regulate the body's circadian cycle. This hormone is stimulated and begins to act by changing between a light environment and a dark environment. This stimulation interacts with the suprachiasmatic nuclei making the nervous system understand this change and luminosity of the environment and respond to the action of melatonin.
