An element have the same number of protons as electrons.
Therefore: if an element x (Lawrencium) has 103 protons, it has 103 electrons.
Proteins help with acting as structural components in the body, speeding up chemical reactions, and transporting substances around the body. Proteins are made up of amino acids, which create enzymes. Enzymes are often affected by environmental factors in the body such as concentration, temperature, and pH.
Proteins are very important for DNA and RNA. (ribonucleic acid)

Answer:
The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.
Answer:
bright blue trait = recessive
yellow trait = dominant
Explanation:
let the letter B represent the gene for skin colour.
This means that the dominant gene is 'B' while the recessive gene is 'b'
A dominant gene is one that is exhibited phenotypically in the presence of both gene variants (heter0zygous state - Bb) while a recessive gene is only expressed phenotypically when it is in a h0m0zygous state (bb)
In order to find out the genotype of the parents, let us consider each cross one after the other.
1. A bright blue female and a bright blue male produce all blue progeny.
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny
From statement 2, it can be deduced that the trait for yellow colour is dominant because a cross of the parents exhibiting this trait produces bright blue offsprings too, meaning that the genetic composition of the parents contains the gene that codes for yellow colour. Since these parents show a yellow colour in a heterozygous state, then the trait for yellow colour is dominant.
Therefore, the genotypes of the parents in each case include:
1. A bright blue female and a bright blue male produce all blue progeny. (bb × bb)
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny (Bb × Bb)
Answer:
The cell bodies of the sensory neurons are located in the dorsal ganglia of the spinal cord. This sensory information travels along afferent nerve fibers in an afferent or sensory nerve, to the brain via the spinal cord.
