Answer:
Involuntary respiration is controlled by the respiratory centers of the upper brainstem (sometimes termed the lower brain, along with the cerebellum). This region of the brain controls many involuntary and metabolic functions besides the respiratory system, including certain aspects of cardiovascular function and involuntary muscle movements (in the cerebellum).
Explanation:
The respiratory centers contain chemoreceptors that detect pH levels in the blood and send signals to the respiratory centers of the brain to adjust the ventilation rate to change acidity by increasing or decreasing the removal of carbon dioxide (since carbon dioxide is linked to higher levels of hydrogen ions in blood).
Answer:
Identical twins are also known as monozygotic twins. They result from the fertilization of a single egg that splits in two. Identical twins share all of their genes and are always of the same sex. In contrast, fraternal, or dizygotic, twins result from the fertilization of two separate eggs during the same pregnancy.

There are three bypass reactions in gluconeogenesis, out of them the one reaction which does not show reciprocal regulation is Pyruvate carboxylase and PEP carboxykinase bypass pyruvate kinase reaction.
The three bypass reactions where the energy transfer of ATP→ADP takes place are:
- Glucose-6- phosphate bypasses the hexokinase step which is a reciprocal step
- Fructose 1,6 bisphosphate bypasses the phosphofructokinase step, this step is also a reciprocal regulating step.
- Pyruvate carboxylase and PEP carboxykinase bypass pyruvate kinase step is not a reciprocally regulated step, this reaction is the last step of gluconeogenesis leading to the formation of 2 molecules of pyruvate.

In everyday life, a "theory" means a hunch, or a figure. In science a theory is the demonstrated consequence of a few trials. i.e. nuclear theory... we realize that molecules exist and that everything is made of iotas, yet in science the expression "law" is not utilized as a part of the case that ensuing confirmation ever surfaced to make a superior or more exact theory.
Answer:
Gene
Explanation:
The genome of an organism is inscribed in DNA, or in some viruses RNA. The portion of the genome that codes for a protein or an RNA is referred to as a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.
