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.
Answer:
No, it is not.
Explanation:
Looking at this chart, this looks to me to be a case of an x-linked recessive disease. (If you want to know how to tell, or got some context that this is not the case, let me know)
Remember that females have two x chromosomes and males have one x and one y chromosome. As this disease is recessive, this means that for a female to exhibit the disease, she must have both x chromosomes have the disease. If she only has one x chromosome with the disease, she's considered a carrier.
On the other hand, males are completely binary, as they only have one x chromosome - either their x chromosome has the disease, and they exhibit it, or their x chromosome does not, and they do not have the disease, nor do they carry it. Thus, males can also not be carriers.
A square on the chart is representative of a male, while a circle is a female. IV-2 is a square, thus he is a male. This means that he cannot be a carrier, so your answer is no.
If any of this doesn't make sense, feel free to let me know! Hope this helps.
The correct answer is : Non-native species is the example that affects biodiversity.
These species can be an agent of unacceptable economic, biological or social aftermath.
However, these species still provides in the regional biodiversity like biotic interactions and species richness and ecosystem services.
Stimulus stimulate the sodium ion voltage gated channel to open in the axon. This allow many Na ion to enter the axon and causes depolarisation as the pd in the axon getting less negative charge (from -70mV to -50mV).
