It is important that it has half because there is a half that comes from each parent. so to equal it all out human gametes have a half set of dna instead of a full set
Answer:
The technology that allows scientists to study the activity of many genes at once is a <u>microarray</u>.
Explanation:
A microarray is a laboratory tool which is used to detect the expressions of a thousand genes at a time and these are in the form of slides which are printed with thousands of tiny spots at a defined position, with each spot having a known DNA or a gene.
Hope this help

Have a nice day!!!!!!
I didn’t see any of the following but I can say that one reason they use it is to record their findings
Answer:
b) opening calcium pores in the membrane
Explanation:
The opening of calcium ions channels facilitates the migration of vesicles containing neurotransmitters in the pre-synaptic neurons to the tip of the post-synaptic membrane. at the <u>neuromuscular junction </u>These neurotransmitters can either be <u>cholinergic or non-chorlinergic.</u> <u>At the tip of the pre-synaptic membranes the vesicles empty their neurotransmitter contents into the synapse.</u>
The neurotransmitters, diffuse through the neuromuscular junction to bind with the receptors on the <u>post-synaptic membrane on the post-synaptic neuron.</u> This stimulates opening of<u> ligand gated sodium ions,</u> and sodium ions diffuse into the post-synaptic neuronal membrane, to cause <u>depolarization</u>. if the stimulus is up to the threshold levels it generate action potential.
Therefore , more calcium ions channels opening produces; more diffusion of neurotransmitters;leading to opening of more sodium channels for depolarization; and IPSP or EPSP generation.
