A food which has been grown without the use of some but not all synthetic pesticides, synthetic fertilizers, or bio engineering could be labeled--- True
What are organic foods ?
-Organic food is produced without using most conventional pesticides, fertilizers made with synthetic ingredients, antibiotics, or growth hormones
When a food is labeled as organic this means that no pesticides have been used in its production?
Produce can be called organic if it's certified to have grown on soil that had no prohibited substances applied for three years prior to harvest. Prohibited substances include most synthetic fertilizers and pesticides.
Are organic food safer?
According to USDA data, organic foods have fewer pesticide residues than conventionally grown produce. But the amounts for both types of produce are within the level for safe consumption.
What is the meaning of organic farming?
organic farming, agricultural system that uses ecologically based pest controls and biological fertilizers derived largely from animal and plant wastes and nitrogen-fixing cover crops.

A motor unit consists of <u>a single motor neuron</u>.
<h3>What is a motor unit?</h3>
Most mature extrafusal skeletal muscle fibers in mammals are innervated by only a single alpha motor neuron. Since there are more muscle fibers by far than motor neurons, individual motor axons branch within muscles to synapse on many different fibers that are typically distributed over a relatively wide area within the muscle, presumably to ensure that the contractile force of the motor unit is spread evenly .
In addition, this arrangement reduces the chance that damage to one or a few alpha motor neurons will significantly alter a muscle's action. Because an action potential generated by a motor neuron normally brings to threshold all of the muscle fibers it contacts, a single alpha motor neuron and its associated muscle fibers together constitute the smallest unit of force that can be activated to produce movement.
Sherrington was the first to recognize this fundamental relationship between an alpha motor neuron and the muscle fibers it innervates, for which he coined the term motor unit.

Answer:Phenolphthalein is a presumptive test that reacts with the heme molecule present in blood. A positive reaction gives a pink color. While bloodstains normally appear red-brown in color, the color of the substrate or the age of a stain may affect the appearance or visibility of the stain.
Explanation:
Answer:
This is an English Language question and I need to choose the most appropriate option.
The answer is Option E
Explanation:
Option A is incorrect because 'each of which' is supposed to be followed by a singular verb 'is' and not 'are'. 'When' is used incorrectly here.
Option B is incorrect because 'which' is not introducing an meaningful non-defining clause in the statement. It is referring to the shark's jaws. The first two clauses are not connected to 'which'.
Option C is incorrect. 'Each one of which are ready' should be 'each one of which is ready'. It is also referring to the shark's jaw.
Option D is Incorrect. The use of a present continuous verb 'lying' is incorrect. The first clause also has not meaning.
Option E is correct.
A through C actually tend to increase reactions. Catalysts, increased surface area and increased concentration all tend to do that. But decreased temperature means decreased energy and speed of the molecules/atoms, thus slowing the reaction.
