The chemicals, neurotransmitters are released to carry a nerve impulse which is an electric signal transmitted by the nervous system. This impulse transmitted from one neuron to another. Examples of neurotransmitters are serotonin in which scientists thinks that a low level of this is one of the causes of depression.
Answer:
1: x = -8 . A vertical line will always be in the form "x=". In this case, x is -8.
2: Since the slope is zero for a horizontal line, we can use the slope-intercept form, y = mx + b to write an equation for it. Since m = 0, it becomes y = b.
3: The equation of a vertical line always takes the form x = k, where k is any number and k is also the x-intercept . (link) For instance in the graph below, the vertical line has the equation x = 2 As you can see in the picture below, the line goes straight up and down at x = 2.
4: In a horizontal line the y value remains the same.
In the point ( -4.-6 ) the y value is -6. the point notation is always written as ( x, y).
The y value throughout the line must be -6 so the equation must be
y = -6

Answer:
The answer is (d) (iv) and (v).
Explanation:
Soil bacterium Bacillus thruingiensis (Bt) produces proteins that kill certain insects like lepidopterans (tobacco dudworm, armyworm), coleopterans (beetles) and dipterans (flies, mosquitoes). Bacillus thuringinesis forms some intracellular protein crystals. These crystals contain a toxic insecticidal protein. The Bt toxin protein exists as an inactive toxin and is converted into an active form due to the alkaline pH of the alimentary canal that solubilities the crystals. The activated toxin binds to the surface of midgut epithelial cells and creates pores which cause cell swelling and lysis and finally cause the death of the insect.
So, the correct answer is '(iv) and (v)'.

The answer is 2. An alteration in the DNA would cause an alteration in the mRNA which is what ribosomes use aa information to produce proteins. So if the message is changed, the product will therefore change
