Answer:
true
Explanation:
Green plants have the ability to make their own food. They do this with a process called photosynthesis, which uses chlorophyll. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide and water into glucose.
Males only have X chromosomes and only pass to their daughters

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.

I am certain that it is due to the rotation of Earth. Note that earth rotates at almost a 1000mph.
Answer:. Nondisjunction during meiosis I in either the male and female gamete
The failure of homologous chromosome to separate at mitosis, or failure of sister chromatids to separate at Anaphase of meiosis I or ii is called non-disjunction.
In this cell division anomaly the unsegregated chromosomes are separated into cells as single chromosomes, therefore extra copies are therefore inherited.This result is one of the cell having an extra copies of chromosomes than others( chromosomes 21.
If this extra chromosome copies is segregated into a sperm or egg, the resulting zygote cells will have extra copy as chromosome 21, and hence Down syndrome.
→It is more common in Meiosis 1 than ii,because of longer duration of the first stage of division than meiosis ii,given rooms to errors.
→Most common in women(with age increase) than men because of exchange of telomeres in them,which worsen with age. Their Meiotic mechanism which weaken with age, and more prone to errors compare to men,
