Answer:
b. epinephrine on beta 2 receptors causes bronchodilation
Explanation:
This is because epinephrine is an hormone and neurotransmitter that stimulate beta 2 receptors which causes signaling and their in presence in airway smooth muscle causes bronchodilation, which counter the activation of the M3 muscarinic receptors in cardiovascular. When stimulate in skeletal muscles it can lead to increased contractility and also to muscle tremors.
Answer:
330
Explanation:
A codon is the sequence of three nucleotides on mRNA that refers for particular amino acid during translation (protein synthesis) process. The four nucleotides arrange themselves in various combinations to produce different codons. The tRNA with corresponding anticodon attach the particular amino acid to polypeptide chain during translation.
Remember there is always a stop (UAA) and start codon (AUG) for the synthesis of polypeptide and stop codon does not contribute for any amino acid. It just terminate the polypeptide chain synthesis. We know that a codon is made up of three nucleotide so our calculation will be.
993-stop codon =990
990/3=330
So that's why 330 amino acid will be incorporated in the polypeptide chain.

Explanation:
Two or more tissues operating together.
MORE INFORMATION;
Cell is that basic unit of life.
Group of cells working together a specific function of tissue.
So, organs are two more tissues operating together. So hope u can get sense..
The digestive, circulatory,
respiratory and excretory systems interact in supplying matter and energy to
body cells and in removing waste. A minor malfunction in one of the systems
could lead to major malfunctions in others. It may eventually lead to cell
damage or death.
All the cells in the body need
oxygen( respiratory system) to maintain functioning--getting energy from food
(digestive system) ingested and removing the waste (excretory system). Also, the respiratory system and excretory
systems remove waste products such as carbon dioxide and urine and sweat. If it
fails, the body will lose homeostasis.
Methods developed to improve
efficiency and effectiveness of one system might help other systems preserve or improve functioning. If one system is
compromised it may be assisted with or replaced by developed methods preventing
it from accompanying damage to other systems.
