3) 2 monoploid cells (also known as haploid)
As relevant to the question here, an object’s mass refers to an intrinsic property of the object while weight refers to a force that depends on the local gravitational field. So, if an object moves between planets with different gravitational pull, the object’s weight would change but its mass would not.
The third option would thus be the correct one (the object of an invariant mass would have a lesser weight on planet B than on planet A).
they are strongest between latitudes of 30°N and 60°N. but they move every year, "following the sun".
ATP
Explanation:
ATP is produced in the cells and its conversion to energy is a single-step process.
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.
