Answer: It correctly explained the motion of the planets
Explanation: i did the test it’s right
There are two types of vesicular transport processes, exocytosis and endocytosis. Endocytosis is the process which is involved in the toxin entering the neuron. This process is where cells intake waste or chemical transmitters which are suspended or dissolved in the extracellular fluid around the cell. <span />
Answer:
15.5g
Explanation:
"The total mass of both chemicals and the containers they are in is 15.5 g." After a chemical reaction, by conservation of mass, the total mass of the products and the two containers after reaction is the same at 15.5g.
Answer:
The correct answer to the question is
d. the nucleus is decaying
Explanation:
A radioactive isotope are variations of of a chemical element with different molecular mass and an unstable nucleus that emit alpha, beta or gamma radiation. An isotope releasing an alpha particle during nuclear decay, releases two neutrons and two protons which make up the alpha particle. If an beta particle is released, then a negative charge equivalent to an electron is released from the nucleus during disintegration. Both forms of nuclear decay results in the release of Gamma radiation.
ome isotopes release an alpha particle during nuclear disintegration; an alpha particle consists of two protons and two neutrons (equivalent to the nucleus of an atom of helium). Others release a beta particle, which is an electron, or negatively charged nuclear particle. Beta particles originate in the nucleus, presumably by breakdown of a neutron into its proton-electron components. Gamma rays are released during both types of radioactive decay.
