ABO blood group system, the classification of human blood based on the inherited properties of red blood cells (erythrocytes) as determined by the presence or absence of the antigens A and B, which are carried on the surface of the red cells.

Answer: DNA condenses into chromosomes.

Explanation: Chromatin carefully packs these DNA molecules into stringy-looking structures called chromosomes. If the DNA molecules in cells were not snaked around histones, the molecules would be 6 feet long when placed end-to-end, according to the National Human Genome Research Institute.

Answer:

C. containing

egg albumen
protease
dilute hydrochloric acid

Explanation:

A protease is a kind of peptidase enzyme that breaks down proteins into peptide molecules. As a digestive enzyme it is located in the lining of the stomach where, relative to the hydrochloric acid in digestive juices, the pH is usually low/ acidic.

Enzymes speed up reaction rates by providing alternative pathways. By modifying the enzyme composition, supplying more collision energy, and changing the collisions between and the ratio of reactants, certain variables will increase the reaction rate.

Proteases function well at 37℃, the typical internal temperature of the human body- this temperature provides adequate energy for the reaction. Similarly, proteases require low pH for the correct configuration, and beyond this pH and temperature, they may become denatured or simply not function well as catalysts.

1: Describe the events of the muscle stimulation and contraction starting with the influx of Ca at the synaptic knob (of the neu

meriva

Answer:

Explanation:

motor neuron is the neuron that have it's connection to a muscle at the neuromuscular junction,. At his junction, a synaptic cleft that has a motor end plate is formed by the activity of the terminal called "synaptic terminal". Diffusion of the acetylcholine across the synaptic cleft then occur which result to the sarcolemma been depolarized, as a result of the depolarization there is a output of Ca2+ and muscle contraction

The effect that botox have on the neuromuscular junction and its function is that there is interaction between Botox and neural transmission which obstruct the acetylcholine to be released, which result to paralysis of muscle.
