Is this a true or false question
Glut4 transporters are groups of <u>inserted into the plasma membrane in response to glucagon.</u>
GLUT4 is an insulin-regulated glucose transporter that is answerable for insulin-regulated glucose uptake into fat and muscle cells. within the absence of insulin, GLUT4 is especially found in intracellular vesicles called GLUT4 garage vesicles (GSVs).
GLUT4 is insulin-responsive glucose transporter, determined within the skeletal muscle, heart, adipose tissue, and brain. GLUT4 is present in vesicles within the cytoplasm of the cells. The binding of insulin to insulin receptors reasons the translocation of GLUT4 to the cellular membrane. The mechanism for GLUT4 is an example of a cascade effect, wherein the binding of a ligand to a membrane receptor amplifies the sign and causes a cellular response. In this situation, insulin binds to the insulin receptor in its dimeric shape and activates the receptor's tyrosine-kinase area.

They can produce 3 types of gametes; gggg, ggtt and tttt in the ratio of 1:2:1. As shown in the table attached, the tetraploid parents produce diploid gametes that combine to form genetically varied offspring.
The genotypes may differ from that of the genotype depending on the interaction of the dominant, recessive and codominant alleles.

Explanation:
1) As human age, their respiratory system also ages making gaseous exchange less and less effective. With age the bone and muscular strength of tissues that keep the respiratory tract open lessen and it becomes the tract slowly collapses. The alveoli also age and become baggy losing their shape. The dead space between alveoli also increases.
This is accelerated by some environmental conditions such as air pollution and smoking. When particulate matter settles in the lungs and alveoli, it causes accelerate damage to the lung tissues and scarring. This is why people in chronically polluted areas, generally speaking, live less longer than people in cleaner environments especially due to respiratory problems they develop.
2) The oral cavity- Includes the lips, teeth, and tongue. The structures serve as articulators. The pharynx and the oral cavity- Both act as resonators that selectively amplify to varying degrees of intensity, fundamental tones and overtones. The larynx- An organ consisting of a cartilaginous framework containing muscles and joints. The vibratile part of the larynx are the vocal folds which are the producers of sound. The Lungs- They supply a stream of air which passes through the trachea.
3) Gas exchange occurs between the alveoli sacs and small capillaries of the circulatory system. Via this exchange, oxygen is delivered from the lungs to the bloodstream. The oxygen attaches to the hemoglobin of red blood cells. The red blood cells then transport the oxygen to cells, such as those located in your muscles.
