Answer:
The symbol of isotopes used for blood flow analysis is 
<u>Explanation:
</u>
- Isotopes are the substances that exhibit the same atomic number but has a different mass number of an element.
- The atomic number explains the number of protons present in the element and mass number explains the number of neutrons available in the element.
- For blood flow analysis, the isotope element is cerium-141 and it is used in the chemical examination of blood flow particles.
- Symbol used for this isotope is
, where 141 indicates the amount of mass present and 58 indicates the proton number and 83 indicates neutron number present in that element.
- The amount of mass in an atom is calculated by the sum of protons and neutrons present in it. Thus mass of isotope is 141 obtained by the sum of 58 protons and 83 neutrons present in that isotope.
Atomic number The atomic number of each element is different than other Elements.
Answer:
True
Explanation:
The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
Answer:
asexual reproduction
Explanation:
some multicellular organisms also reproduce by producing genetically identical clones of themselves. any form of reproduction that results in new individuals that are genetically identical is called asexual reproduction
Answer:
because a fruit holds the seeds it needs to reproduce and continue living.
