Answer: D. protection against a recent infection or disease is needed immediately
Explanation:
Passive immunisation is used when there is a high risk of infection and there is insufficient time for the body to build its own immune response or to mitigate the effects of active or immunosuppressive diseases.
Passive immunisation may be offered when people are unable to synthesise antibodies and when they have been exposed to a disease to which they have no protection. example of passive immunotherapy include monoclonal antibodies (MABs) or magic bullets which targets cancerous cells.
Hence, the correct option is D.
Nerve cells or neurons are, fundamentally, cells of the nervous system, they are responsible for the transmission of nerve impulses and communicate with one another through connections called synapses .
Neurons are typical of all vertebrates, although in the rest of the animal kingdom there are other cells that have similar functions.
So, the right answer is A. Horse.
Answer:
This question lacks options, the options are:
A) The financial costs for the farmer would be lowered.
B) Federal agencies could initiate legal action against the farmer.
C) The farmer may be held responsible for increasing chemical pollution.
D) The farmer's expenses for pest control would increase due to an increase in bee population.
The answer is A.
Explanation:
Genetic engineering or modification is a process whereby the genome of an organism is manipulated in order to achieve a desirable trait in the organism. In this question, a farmer uses an approved genetically engineered corn plant, which produces pollen that can make its own toxins to repel pests.
Using this genetically modified corn plant means that the farmer no longer require the application of chemical pesticide to control the pests affecting his corn plant. The impact on the farmer of growing such a variety of corn is that the financial costs for the farmer would be lowered since he won't have to purchase chemical pesticides any longer.
The heat causes them to open up and flow air
Answer:
Polydactyly in the Amish population is an example of Founder effect
Explanation:
Founder effect is defined as loss of genetic variation as it occurs when a new population is formed by small number of individuals that are diverge from the a large population.
Polydactyly is an example of these founder effect that causes formation of extra finger which takes place when a a polydactyly man marry within their own community. As a result,genetic variation does't takes place among them and thus the offspring carry recessive genes which leads to this type of rare genetic disease.
