Answer:
Herd immunity is a form of indirect protection from infectious disease that can occur with some diseases when a sufficient percentage of a population has become immune to an infection, whether through vaccination or previous infections, thereby reducing the likelihood of infection for individuals who lack immunity.
Explanation:
Vaccines create immunity without causing illness or resulting complications. Herd immunity makes it possible to protect the population from a disease, including those who can't be vaccinated, such as newborns or those who have compromised immune systems.

Explanation:
Hypophosphatemic rickets is a disorder characterized by hypophosphatemia (low level of phosphate in the blood), defective intestinal absorption of calcium, and rickets (impaired mineralization of cartilaginous growth plates) or osteomalacia (impaired mineralization of the osteoid) unresponsive to vitamin D. It can be inherited or acquired.
When it comes to inheritable hypophosphatemic rickets, the disorder is most often inherited in an X-linked dominant manner. This means that the gene is inherited through the X chromosome and that one dominant allele is enough to cause it.
As the mother is heterozygous for the trait, she has one dominant and one recessive allele (XHXh). The father has one X chromosome, which he inherited from his mother, and as he has the condition, the dominant allele will be present on it (XHY).
This means that, if the child is a girl, she will definitely have the disorder. Girls inherit one X chromosome from each of their parents. Even if she inherited the one with the recessive allele from her mother, she would get the one with the dominant allele from her father.
If the child is a boy, he has a 50% chance to inherit the condition. Boys inherit the Y chromosome from their father and the X chromosome from their mother. As the mother is heterozygous, he can either get the chromosome without the dominant allele or the one with it. This means that there is a 50% chance of inheriting the disorder.
If we say that there are equal chances of this couple having female and male children, when we combine these results, we get a 75% chance of them inheriting hypophosphatemic rickets.
Answer:
The correct answer is- TAAGCCGATAAATGCTAACGGTA.
Explanation:
DNA is a nucleic acid molecule made of two strands. Each strand is made up of nucleotide bonded via phosphodiester bonds. Each nucleotide is made up of- 5C deoxyribose sugar, a phosphate group and nitrogenous bases.
DNA replication produces an exact copy of the DNA molecule through complementary base pairing. The complementary strand is formed by adding nucleotide through DNA polymerase which adds base pairs according to the Chargaff rule. The Chargaff rule states that A will bind T via two hydrogen bonds and G will bind C via three hydrogen bonds.
Therefore, the complementary strand will be-TAAGCCGATAAATGCTAACGGTA
