Answer:
interspersed, transposon-derived repeats, simple sequence repeats.
Explanation:
In the human genome, not only the protein coding genes are present, in fact these genes make up just a very little portion of the human genome about 1.5-2% of the entire human genome. Repeats make up about 48% of the human genome which is the largest and the rest include, conserved non coding sequences (43.5%), heterochromatin regions etc.
Some of the repetitive elements includes LINEs, SINEs, DNA fossils tranposoon, Retrovirus like elements. all these are transposable elements which are mobile DNA sequences that can migrate to different regions/areas of the genome.
Microsatellites (simple sequence repeats) are tracts of repetitive DNA in which certain DNA motifs are repeated normally 5-50 times.
<h2>Dinoflagellates thrive in bahia fosforescente</h2>
Explanation:
- Dinoflagellate, are one-celled aquatic organisms having two dissimilar flagella.
- It has a characteristics of both plants and animals.
- Most of the dinoflagellates are marine, but some live in freshwater habitats.
- Bahia fosforescente is one of the phosphorescent bays where millions of glowing marine dwellers such as dinoflagellates cause the lake to glow a bright blue in night.
- Dinoflagellates has the characteristics of Bioluminescence which they use it as a defense mechanism.
- During night, due to the bioluminescence of dinoflagellates,water can have an appearance of sparkling light.
- Dinoflagellates takes their nutrients from marine organisms, thus they grow or develop well in bahia fosforescente.
Answer:
increase anxiety; decreased vulnerability to overreact to stress
Explanation:
Serotonin (5-HT) is a natural neurotransmitter that carries signals between nerve cells (neurons) throughout the body. This neurotransmitter (serotonin) is responsible for regulating many biological functions (e.g., mood, digestion, sleep, etc). Moreover, it has been shown that there is an association between low cerebrospinal fluid 5-hydroxyindole-acetic acid (5-HIAA, the principal serotonin metabolite in the brain) levels and the risk of developing depression or destructive behaviors. In addition, serotonin concentration can also be elevated in situations of anxiety and/or stress. Antidepressants such as Prozac, Zoloft and Paxil act as serotonin uptake inhibitors that increase serotonin concentration at the synaptic site. Like other drugs, these antidepressants may lead to increase anxiety and decrease the vulnerability to react to stress by downregulating sensitivity to serotonin released during natural stress situations.
