Biology
1 answer:
luda_lava [24]3 years ago
7 0

Answer:

Ions are atoms with a positive or negative charge.

Explanation:

Ions are atoms or molecules that, when subjected to the phenomenon of ionization, gain or lose electrons, ceasing to be neutral and acquiring an electric charge.

The charge that atoms or molecules possess can be positive —if it has lost electrons— or negative when it acquires electrons. The negatively charged particle is called anion, and when it is positively charged cation.

The other options are not correct because of:

  • <em>There are usually as many or more neutrons than protons. </em>
  • <em>Uncharged atoms are neutral. </em>
  • <em>The number of protons or neutrons does not affect the electric charge of the atom.</em>
  • <em>Atoms that joined in fixed proportions can form molecules.</em>

Which of the inner transition metals is critical to the nuclear power industry.
Rom4ik [11]

Answer:

<u>Uranium</u> is the  inner transition metals is critical to the nuclear power industry.

Explanation:

Uranium is a common transition metal found in rocks and is used for nuclear fission reactions. In a nuclear fission reaction, a neutron atom is hit on a uranium atom. As a result, the uranium atoms breaks down releasing huge amounts of energy. Also, more neutrons are released by the breakdown and hence the this neutron hits other uranium atoms and the cycle continues. The most active radioisotope of uranium being used in nuclear fission reactions is U-235.

Yuki888 [10]
When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides by way of meiosis, it produces four cells, called gametes. Gametes are more commonly called sperm in males and eggs in females.

When a large number of species, sometimes entire major taxa, go extinct in a short period of time on the geological scale, the c
Ann [662]

Answer: C. Radical global climate change.

Explanation:

The entire taxa of the species can be wiped out due to an large catastrophic event associated with the change in the climate. As the climate becomes warm the chances of undergoing the global precipitation rate will change. The climate being an important abiotic factor under unstability is likely to affect the amount of rainfall, snow fall, drought and conditions of desertification. All these factors can be responsible for the removal of the entire taxa of the species in short time.
