Answer:
Megaspore—2n.
Explanation:
Angiosperms are the fruit bearing plants and reproduce by the process of sexual reproduction. The chromosome number are specific at each stage of the cell cycle of the angiosperms.
Microspores , egg are haploid. Zygote is diploid in nature. Megaspores get germinate into the female gametophytes and these are haploid in nature. Megaspores are also haploid in angiosperms.
Thus, the correct answer is option (b).
Answer:
As chlorine has 7 valence electrons, it tends to form bonds to gain one electron (to get a full valence shell of 8).On the other hand, potassium has one valence electron, so it tends to lose this electron to other atoms (and
become a cation)
Answer:
so according to me I think it should be a <em><u>true</u></em>
Answer:
<em>Applications of dipole moment:
</em>
<em>
</em>
<em>(i) Ionic character can be calculated using the value of dipole moment.
</em>
<em>
</em>
<em>% of ionic character =
</em>
<em>
</em>
<em>=100* (Experimental value of dipole moment/Theoretical value of 100% ionized molecule)
</em>
<em>
</em>
<em>(ii) Geometry of the molecule can be predicted using the dipole moment.
</em>
<em>
</em>
<em>(iii) Dipole moment is helpful in predicting nature of the molecule. Weather it is polar or non-polar in nature.
