Minchanka [31]3 years ago

Answer:

Sexual reproduction can be described as the method of reproduction in which the offsprings produced will have half the chromosomes as compared to the parent cell. The other half of the chromosomes to make a complete set would arise from the other parent. In this way, the offspring produced will carry half of the chromosomes from the female parent and half from the male parent.

Crossing over and independent assortment are two phenomenons of meiosis due to which genetic diversity occurs and the offsprings born are not exactly similar to the parent cell.

Enter a balanced nuclear equation for the production of lead-212, used in the treatment of some cancers, from the beta decay of
MariettaO [177]

Answer:

\frac{212}{81}Tl ------>\beta  + \frac{212}{82}Pb

Explanation:

Beta emission involves the conversion of a neutron to a proton, an electron and a neutrino. This leads to a reduction in the neutron-proton ratio.

During a beta emission, the mass number of the parent and daughter nuclei remain the same. The atomic number of the daughter nucleus increases by one unit above that of the parent nucleus as we can see from the equation.

Hence, the daughter nucleus is found one place after its parent in the periodic table.

When barium becomes positively charged, it forms a(n): (2 points)
mart [117]

Barium forms cation : Ba²⁺

<h3>Further explanation</h3>

Given

Barium element

Required

Ion type

Solution

Barium with the symbol Ba is an alkaline earth metal element having the atomic number 56

Electron configuration of Barium: [Xe] 6s2

If we look at this configuration, then Barium will try to achieve stability by removing 2 electrons so that the electron configuration is the same as the noble gas Xenon (Xe)

Because it removes 2 electrons, Barium has the number of protons> the number of electrons so that the charge is positive and forms a cation

yKpoI14uk [10]
<h3>Answer:</h3>

A coordinate bond

<h3>Explanation:</h3>
  • A chemical bond is a force of attraction between two or more atoms of elements.
  • Covalent bond is a type of chemical bond that occurs between non-metal atoms.
  • It occurs as a result of sharing of electrons between the non-metal atoms.
  • Atoms involved in covalent bond formation may contribute equally to the bond formation or the electrons shared may come form one of the atoms.
  • When the electrons shared in a covalent bond are derived from one atom, then the covalent bond is known as a coordinate bond.
