[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]\Huge\text{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.

Which scientist did NOT help develop the basic cell theory?
A. Rudolf Virchow
B. Charles Darwin
C. Anton van Leeuwenhoek
D. Robert Hooke
E. All of the above helped in developing the cell theory
PLEASE HELP!!
The given statement is false and the cell hypothesis was created by Rudolf Virchow, Theodore Schwann, and Matthias Jakob Schleiden, hence option B is correct.
What is cell theory?As a result, van Leeuwenhoek and Schwann did not independently develop the cell hypothesis.
The scientific idea that cells make up living beings, that they are the fundamental structural and organizational unit of all species, and that they all originate from previously existing cells is known as cell theory.
Typically, three scientists Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow are credited with creating the cell theory.
Therefore, Schwann and Schleiden proposed that cells were the fundamental building block of life in 1839.

what s the function of the cell wall ?
The function of the cell wall for a eukaryote cell is provide structure, support, and protection for the cell with its rigid outer layer. The cell wall in plants is composed mainly of cellulose and contains three layers in many plants. The three layers are the middle lamella, primary cell wall, and secondary cell wall.
Put these layers in order of when they happened oldest to youngest.
Answer:
L. E, F, G, H, I, J, K, D, C, B.
Explanation:
L is the oldest layer because it is present below all of the layers followed by E layer then F, G, H, I, J, K, D, C and B. B is the youngest layer because it is present above of all layers and formed recently. the layers formed after B layer is C layer which is younger than the rest of the layers but older than B layer. D layer is also older than C and B layer but older than the remaining layers.
How does a lack of water in an environment affect the amount of carbon dioxide a plant absorbs?
Answer:
the lack of water in an environment affect the amount of carbon dioxide a plant absorbs by rising carbon dioxide concentrations will increase plant growth. More rapid leaf area development and more total leaf area could translate into more transpiration. Rising carbon dioxide concentrations will decrease leaf stomatal conductance to water vapor. This effect could reduce transpiration.

What is carbon dioxide?More rapid leaf area development and more total leaf area could translate into more transpiration.
Rising carbon dioxide concentrations will decrease leaf stomatal conductance to water vapor. This effect could reduce transpiration.
Carbon dioxide (CO2) is a colorless gas with a sour taste and a slight harsh odor. It is one of the most significant greenhouse gases associated with global warming, but it only makes up a small portion of the atmosphere on Earth (roughly 3 volumes per 10,000).
Therefore, The lack of water in an environment affect the amount of carbon dioxide a plant absorbs by rising carbon dioxide concentrations will increase plant growth.

Suppose that this population of mice has stabilized so that both white and brown appear. White mice survive better in the winter and brown mice survive better in the warmer months. If a group of these mice migrated to an area that didn't get snowy in the winter, what do you think would be the long term effect on the color of these mice? Explain why.
Answer:
more brown mice would survive as the white ones without the snow to camouflage them from predators would get picked off by predators more than the brown ones
Explanation:
Over a long period of time, the population of white mice will reduce or would disappeared.
What is Natural Selection?It is a method of evolution in which the organisms of a population are selected by specific parameters.For example - color, running speed, etc.In a place where the winter is not snowy, the white mice will be easily caught by predators. Brown mice have less chance to be caught by predators, hence surviving better in non-snowy places.Therefore, over a long period of time, the population of white mice will reduce or would disappeared.

the diagram shows a model of how a hydra reproduces by budding
Answer:
B. It shows offspring that have the same genes as the parent.
C. It shows asexual reproduction.
Explanation:
Hydra reproduces by budding which is kind of asexual reproduction. In budding, a small bud appears on the body of that organism and grow in size with the passage of time and finally detached from the parent body. so no fusion of gametes occurs so no chance of genetic variation. The offspring have the same genes as the parent because it forms from one parent.

1. Fallopian tube
2. Uterus cavity
3. Bladder
4. Urethra
5. Ovary
6. Ovary
7. Uterus
8. Vagina
Explanation:
The vagina is a muscular tube-shaped connection that extends from the vaginal opening to the uterus. Vagina walls are very muscular, which allows contraction and expansion movements. It is located just between the urethra/bladder and the rectus. Menstruation, copulation, and birth occur through the vagina.
The uterus is a muscular and hollow organ, also located between the bladder and the rectus. The uterus wall is formed of three layers: perimetrium, mesometrium, and endometrium. This organ is separated into two parts: the uterus body and the cervix, which protrudes to the superior area of the vagina. Here is located the uterine opening that communicates the vagina with the uterus cavity. The final rounded portion is called "uterus fundus", and each of the two extremes is called "uterus horn". These horns are united to the Fallopian tubes.
Fallopian tubes are ducts that communicate each of the ovaries with each of the uterus horns. These tubes receive the oocytes that are getting out of the ovaries and carry them to the uterus. In their way, they might meet a spermatozoid and be fertilized.
Both ovaries have an oval shape, of approximately 3 cm in length each and 1 cm in width. They are located at each side of the uterus and are in charge of the production of the feminine gametes (the whole ovulation process).

How do typical human body temperature and pH explain why lactase can work efficiently in the human body of most humans?
Answer:
Lactase requires 6 pH and 37 degree Celsius temperature.
Explanation:
Lactase can work efficiently in the human body of most humans because the pH and temperature of the body is favorable for the lactase to work. Lactase has a range of pH from 2 to 7 but work best at the pH 6 and at the temperature of 37 degree Celsius which is the human body temperature and pH so that's why the lactase can work efficiently and effectively in the human body.
