Answer: (Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure
(Function) mRNA: carries the information in the DNA to the ribosomes where it is translated into amino acids of proteins, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain during protein synthesis, tRNA: acts as an adaptor molecule, which identifies correct amino acids corresponding to the anticodon present on it

Answer: A mantle plume is an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. ... While most volcanoes form along tectonic plate boundaries, mantle plumes and hot spots lead to their development as well. Hot spot volcanoes occur far from plate boundaries.
Explanation:
During exercise, a number of changes occur to maximise the body's oxygen intake. Firstly our heart rate/ pulse increases. This is due to the heart beating much faster and more forcefully to pump blood faster around the body.
Our breathing rate increases to intake more oxygen and exhale more CO2.
The smooth muscle in our trachea and bronchi relaxes to increase the lumen size thus making breathing easier. Adrenaline may also be released leading further amplifying these changes as well as reducing blood flow to the gut and thus peristalsis occurs at a much slower rate.
Also when we exercise we respire more, producing heat, which must be expelled. This may be done through sweating. Another physiological change that occurs is vasodilation of arterioles closer to the skin to allow more blood to flow closer to the skin, allowing more heat to radiate out.
Ryan was born genetically male but has external genitals that are completely female. He would be referred to as female pseudohermaphrodite. It’s a term used when a male is born with an ovary or there are external genitals which looks like an intermediate of a female reproductive organ. The opposite of which is a male pseudohermaphrodite. Pseudohermaphroditism in general is usually linked to Androgen insensitivity syndrome or 5-alpha-reductase deficiency.
