Answer:
A cell wall, a broad central vacuole, and plastids such as chloroplasts are all present in plant cells. The cell wall is a dense layer that covers the cell and provides structural support and protection. It is located outside the cell membrane. The turgor pressure against the cell wall is maintained by the central vacuole.
Explanation:
Answer:
A. Heat and Humidity
Explanation:
The hot, damp conditions on the forest floor allow for the rapid decomposition of dead plant material.
The correct option is 3.
Enzymes are biological catalysts which speed up the rate of biochemical reactions inside the cells. Enzymes are very specific in action and they require specific conditions called optimum conditions for them to function optimally.
When the optimum conditions are not met, an enzyme's activity will be lowered or totally stopped.
Conditions that affect the optimum activity of an enzyme include: temperature, pH level and regulatory activity of regulatory enzymes and hormones.
Prader-Willi syndrome (PWS) is a gentic disorder which has an impact on numerous physiological systems. PWS affected individuals (specifically babies) experience delayed growth, significant hypotonia (low muscle tone), and feeding issues. It does effect circadian rhythms in mice models.
SNORD116, often referred to as HBII-85, is a non-coding RNA (ncRNA) molecule that contributes to the alteration of other small nuclear RNAs (snRNAs). Unlike the majority of other snoRNAs, SNORD116 is not significantly complementary to ribosomal RNA and is expressed widely in the brain (but not in PWS patients).
According to the studies, SNORD116 cause sleep defect in patients with Prader-Willi syndrome. Same observation was seen in mouse models too. Paternal expression of SNORD116 is thought to be a potential gene for the sleep disruptions/circadian rhythm’s that the majority of PWS sufferers.
