Answer:
Explanation:
Answer:
Insertion (addition)
Explanation:
As you can see, a T was put into the strand, and moved the CAC one place to the right. It didn't take the place of any nucleotide. This shows that the extra T caused an Insertion Mutation.

compare the different types of sensory receptors and to predict the results of damage of each
Answer and I will give you brainiliest
Answer:
Sensory receptors are primarily classified as chemoreceptors, thermoreceptors, mechanoreceptors, or photoreceptors.
..
Damage to sensory receptors can result in a loss or alteration of the sense that the receptors are responsible for detecting, which can greatly impact an individual's daily life.
What are sensory receptors?Sensory receptors are specialized cells or structures that respond to specific types of stimuli, such as light, sound, or pressure. There are several types of sensory receptors, each of which is responsible for detecting different types of stimuli.
Photoreceptors, such as the rods and cones in the eye, detect light and are responsible for vision. Damage to these receptors can result in vision loss or blindness.Mechanoreceptors, such as those in the skin and inner ear, detect touch, pressure, and movement. Damage to these receptors can result in numbness, tingling, or difficulty with balance and coordination.Thermoreceptors, such as those in the skin, detect changes in temperature. Damage to these receptors can result in the inability to sense temperature changes and the risk of burns or hypothermia.Chemoreceptors, such as those in the nose and taste buds, detect chemicals and are responsible for the sense of smell and taste. Damage to these receptors can result in a loss of smell or taste, or an altered sense of smell and taste.Nociceptors, detect pain and are responsible for the sense of pain. Damage to these receptors can result in an inability to feel pain.Learn more about sensory receptors, here:

Many proteins are regulated by the binding of GTP or GDP. Which form is the active state of the protein
Answer:
GTP-bound form
Explanation:
Such a receptor may be associated with the GDP-regulated G-stimulant protein system. When the neurotransmitter binds to the receptor, the protein G-GDP complex is activated by separating its β subunit. When the ligand "sticks" to it, it releases GDP and allows GTP to bind. This form of the G protein that binds GTP, is the activated ("on") form of it. When it is "on" it releases signals into the cell. After a short period (seconds or less) the G protein hydrolyzes the GTP to GDP and itself "turns off".

What element is in adenine that is not in
ribose?
Answer:
Nitrogen
Explanation:
Adenine is one of the four nitrogenous bases while Ribose is one of the two sugars (carbohydrates) that make up a nucleotide. Adenine is structurally composed of 5 carbon atoms, 5 hydrogen atoms and 5 nitrogen atoms to form the chemical formula C5H5N5 whereas ribose is structurally composed of five carbon atoms, ten hydrogen atoms, and five oxygen atoms to form the chemical formula; C5H10O5.
Based on the above explanation, it is evident that the element present in Adenine but not in Ribose is NITROGEN. Nitrogen is a major constituent of all nitrogenous bases (Adenine, Guanine, Cytosine and Thymine (Uracil).
