The bond formed by donating electron is called Ionic bond.Ex LiF,NaCl
Bond formed by mutual sharing of electron between two atoms is know as Covalent bond. Ex CO, IBr
hydrogen bond is the bond formed between the hydrogen and highly electro negative compound. Ex: H₂O, NH₃
Polar bond is a covalent bond which is between two atoms where the electrons are unequally distributed.
Answer:
I think the correct answer is option ( A )
Explanation:
I'm not sure
When a wave has a height of 5 feet and a wavelength of 15 feet then it has a wave base of 7.5 feet. Wave base is equal to the half of the wavelength so if you consider your wavelength to be 15 feet then it is divided into 2 that would give you answer of 7.5 feet.
the answer is 7.5 feet

Answer:
Since both Anthony and Sara are healthy carriers of the gene that causes cystic fibrosis, the chance of having a child with this disease are 1:4 (option D).
Explanation:
The inheritance pattern of cystic fibrosis is autosomal recessive, and considering that both parents carry the abnormal CFTR gene, it can be said that the parental genotypes are:
<em>Anthony N/Qf
</em>
<em>Sara N/Qf
</em>
Where N is the normal gene and Qf is the abnormal gene.
Since this is an autosomal recessive disorder, only the homozygosity of the defective allele will cause the disease to manifest
:
N/Qf X N/Qf
<em>Alleles N Qf
</em>
<em>N N/N N/Qf
</em>
<em>Qf N/Qf Qf/Qf
</em>
- The chances of having a healthy child are 25%.
- The chances of having a carrier child are 50%.
- The chances of having a child with cystic fibrosis are 25%.
Therefore, the chance of Anthony and Sara having a child with cystic fibrosis is 1:4.
