Q1. Pedigree is the recorded lineage of a family. A pedigree chart is actually a diagram showing an appearance and occurrence of phenotypes in several generations. It is used to find a probability of a child inheriting a particular trait or to discover is the trait autosomal or sex-related.
Q2. The presence of a trait in a pedigree chart is shown as filled-in figure. If a square or a circle in the pedigree chart are white (empty), then a person does not have a particular trait. If a figure is filled in (usually black), then a person has a trait. If a figure is half-filled in (e.g. it is half black half white), then a person is only a carrier of a trait but the trait is not expressed.
Q3. In the pedigree charts, squares present males and circles present females. If a female is healthy, the circle is empty (white). If a female is affected with a trait, the circle is filled in (usually black). Similarly, if a male is healthy, the square is empty. If a male is affected with a trait, the square is filled in.
Q4. The presence of dimples is a dominant trait. <span>In dominant traits, traits do not skip generations, unlike recessive traits. From the pedigree, the disorder did not skip any generations. This suggests that the disorder is dominant. If it was recessive, in some generation the trait would not be expressed.
Q5. If a pedigree chart of a family is known, then the occurrence and appearance of a trait can be predicted. For example, if it is known whether a disease is dominant, recessive, or sex-linked, then a possibility of getting a child with a disease can be easily calculated.</span>
I am not really sure about the city, but if we look at the country, its BORDERS would be the same analogy for the cell membrane. I am saying this because cities dont really have a border .
The polio vaccine works as :
It triggers the immune system to produce antibodies to fight the disease causing agent.
Option 1 is the correct answer.
Explanation:
Polio vaccine is attenuated disease causing virus which helps in the production of antibodies to fight the disease. The immunity for polio gets develop in the individual given polio vaccines.
Jonas Salk discovered the the vaccine for polio by using inactivated polio causing virus.
The polio vaccine produces antibodies in the blood when interaction with polio virus is there.
The paralysis of the legs can be prevented as polio virus do not reach the nervous system and spinal cord of the individual.
There are two types of polio vaccines given across the globe:
oral polio vaccine and inactivated polio vaccine (via injection)
Answer:
ecosystem
Explanation:
An ecosystem is the biological community of organisms that interact with each other and they share the same physical environment. Even though it is man-made, the aquarium still represents an ecosystem. The aquarium itself is the physical environment in which all the organisms in it live. Since all the fishes live together, they interact with each other in one way or another, thus creating an interactive biological community, resulting in a micro ecosystem.
Mitosis is the type of cell division the question is asking for
