a person can be immunised against a disease by injecting them with an inactive form of a pathogen.
explain how this makes a person immune to the disease in a paragraph
(ill mark u brainlist)
a vaccine works by training the immune system to recognize and fight pathogens, either viruses or bacteria. so certain molecules from the pathogen must be introduced into the body to trigger an immune response. so basically your not really immune your body will just know how to deal with it
[tex]\Large\textbf{ACTIVE AND PASSIVE IMMUNITY}[/tex]
Active Immunity, Immunity which is acquired by the own immune response of the body.
Passive Immunity, Immunity which is acquired and dependent upon the antibodies transported from another person or even an animal. A person's immune system does not acquire or make the antibodies itself. A newborn baby acquires passive immunity from its mother through the placenta.
x---------------------------------------------------x
[tex]\Large\textbf{Vaccination:}[/tex]
Vaccination is a artificial active immunity. Artificial because the antibodies are not acquired by any natural infection but it is injected into the healthy body of the person. It is Active immunity because the body does not get already made (from other animal) antibodies but it acts on the small amount of the pathogen which is injected in the body and acquires the antibodies itself. So the person acquires antibodies naturally acting on the antigen. Antigen is any foreign agent which triggers the immune system to produce antibodies against it. Vaccines contains antigen which is a harmless form of the bacteria or a virus that causes the disease you are being immunised against. The bacteria or virus are in small proportion and greatly weakened in the vaccine so they just trigger an immune response without causing any real damage. When Vaccine is injected in the body, the immune system starts to make antibodies of different forms against the antigen(Virus or bacteria in the vaccine). When the appropriate shape antibody reacts with the antigen and forms antibody-antigen complex which destroys the antigen. This means that type and shape of antibody is perfect to work against that antigen, then the immune system start forming only those kind of antibodies in great proportion and the Person gets immunised by the vaccine in a natural way.

Being genetically identical to the parent is most advantageous for organisms in which situation?
A.
Many offspring are needed in a very short amount of time.
B.
The environment is just like the one the parent lived in successfully.
C.
Mates cannot be found easily and the species is dying out.
D
The environment is changing and fast reproduction is needed.
Answer:
B
Explanation:
In asexual reproduction organisms give rise to genetically identical clones and reproduce in higher amounts, hence option d environment is changing and the need for fast reproduction is correct.
What is genetically identical?The children are clones of both the parent and each other. Asexual reproduction has several advantages, including the ability to fast increase the population when conditions are favorable.
There is just one parent required. During sexual reproduction, two people's genetic material is united to generate genetically diverse children who differ from their parents.
It is assumed that the genetic variety of sexually generated offspring gives species a higher chance of survival in an uncertain or changing environment.
Therefore fast reproduction is needed, because the environment is changing, and asexual reproduction makes a higher population, hence option d is correct.

How many calories are required to heat 10 mL of water from 25 C to 35 C
Answer:
[tex]Q = 5,46,000[/tex] joules

As we know
[tex]Q = mc \Delta T\\[/tex]
Q is the Heat Energy
M is the mass of the substance releasing /absorbing heat
C is the specific heat capacity [tex]= 4200[/tex] Joules per kilogram per degree
[tex]\Delta T[/tex] is the change in temperature

Explain briefly HOW we have different cell types (blood, skin, muscles, nerves, etc.) *
Answer: Everybody is born with different blood cells, skin tone etc . That depends on your parents and the actual spermatozoon that got to the egg and eventually turned out to be you . That means that is up to the genes and races that you’ve been mixed with and created of . Sometimes even siblings have slight differences in their skin tone ,eye color etc . The genes and races or stuff like that, that you’re mixed with may pop up in different ways for you and your siblings i don’t know if that makes sense

Answer:
Explanation:
Early interphase is called the G1 phase of the cell cycle. G1 is the time during which a cell grows to its proper size by making more cytosol, the liquid inside a cell. An increase in cell size means the cell must make more protein and membranes. ... Cells that mature and never divide again stay in the G0 phase.
