A vaccine is a substance that contains all or part of a noninfectious version of a disease-causing organism. When the vaccine is administered to a person, the person's immune system attacks the noninfectious version of the organism and learns to recognize its surface proteins. The next time the immune system comes in contact with the same surface proteins, it has a defense already prepared in order to respond quickly to the invading organism. In this way, a vaccine gives people immunity to the disease-causing organism.
Vaccines can be life-saving, but there have been a few cases of people catching a disease from the administered vaccine.

Outline seven soil pollutants and state two effects of each of this seven soil pollutants.
[tex]\bold{\huge{\underline{ Answer }}}[/tex]
Soil pollutants are substances which contaminates the soil. Soil pollutants are very harmful substances ,they makes the soil toxic . The presence of these substances in higher concentration directly affects the ecosystem, earth etc.
Here are some major soil pollutants :-1) Industrial wastes
Industrial wastes are the common soil pollutants. The discharge of industrial waste in the soil makes it very toxic and directly affects the growth of plants (agriculture) .Industrial waste also affects the life of some organisms like earth worms which makes the soil more fertile.2) Pesticides
Pesticides are the substances which are generally used to kill the pestes. It includes Insecticides, herbicides and fungicides. The higher concentration of pesticides in cropfield directly affects the human health and responsible for soil pollution, water pollution etc.3) Hydrocarbons
Hydrocarbons are the substances which are composed of hydrogen and carbon. Only some hydrocarbons are responsible for soil pollution as they are very harmful for living organisms. for example the most harmful hydrocarbons is PAHs ( Polycyclic aromatic hydrocarbons) .PAHs in soil affects the growth of plants and it is indirectly responsible for the cancer in humans.4) Metals
Most of the people don't know that the higher concentration of some metals makes the soil very toxic . The concentration of these metals in soil directly kills the human beings and other living organisms.5) Non - biodegradable substances
Most people throw the trash in the soil even they know that soil can't degrade the non - biodegradable substances. When these non - biodegradable wastes eaten by street animals it directly affects the health of those animals and disturbs the ecosystem.6) Human activities
Some people really don't care about the environment. They always do ,what they want to do without even thinking about its consequences on the environment. They throw Cigrattes in the soil, Drop alcohol in soil .These activities makes the soil toxic and the crops that are grown in contaminated soil directly affects the human health.7) Acid rain
It is major reason for the contamination of soil. Some people thought that, It is the natural cause of soil pollution but that's not the reality. Humans are the one's who are responsible for acid rain. Contamination of these acids makes the soil very toxic that it kills the plants on the spot.Answer:
See below.
Explanation:
1) Plastic / Glass:
● Non biodegradable substances & takes a long time to decompose.
● Harmful substances are released into the soil.
2) Acid rain:
● Changes the acid level of the soil.
● Causes harm to the plants, insects & ground water.
3) Pesticides / Insecticides / Artificial fertilisers:
● Alters the health of the soil.
● Causes harm to the plants & the organisms living in the soil.
4) Heavy metals (merculy, arsenic etc.)
● Causes toxic harm to plants & animals.
● Highly poisonous .
5) Industrial wastes:
● pH level of the soil can be altered.
● Makes ground water either too acidic or too basic.
6) Radon:
● Harms microorganisms .

what if the sun disappears one fine day ?
state the consequences of such a situation over the solar system.
thankyou ~
Explanation:
Sun plays an important role in our solar system especially planet like earth are dependent on sun for food, water and air. Sun helps to balance the ecosystem on earth.
Here is an assumption what would happen if sun disappear for one day only, it would be more curt if it disappear forever but from POV of one day below are certain consequences of such a situation over solar system,
You might be thinking if sun disappear then we would be seeing the moon for a whole day but don't forget, moon don't have it's own light, it reflects the rays coming from sun if sun disappear then surely moon would be like a ball kept in dark.It would happen for the first time if an asian man calls to someone in Europe, usually when here is night there is day and vica versa, but this time both will have same appear (night only)There's a idiom in Indian Hindi language that says "seeing the stars during the day time" which we use when we are going through something worse that we see the stars during daytime, but this time every human being on earth will see the stars during daytime, do not forget stars have their own light, they are not sun dependent.For the first time Night Blooming Jasmine will bloom and spread it's fragrance for 24 hours.Often when the earth revolves around its axis, a certain part of it receives light from the sun.But for the first time the earth will rotate around its axis without the sunlight falling on any part.people who are not allowed to go out of the house at night time can now enjoy the night out in the day too.Those trees and plants who slept in the hope that they would cook food in the morning with sunlight, they would not even know that their food has gone missing.Our ozon layer will have it's first leave from his duty.The bad thing is for the patients of night blindness, they will not be able to see this imaginary scene.Thanks for joining brainly community!

Peppered moths come in two color variations, as shown below.
Prior to the Industrial Revolution, the majority of the population in England consisted of the light colored variation. The dark colored moth became the dominant variation by the end of the 20th century and remained so for almost 100 years. Today, the light colored variation is dominant again.
What is the best explanation for this?
A. Populations with two variations have a better chance of survival than populations with more.
B. A single variation can be beneficial under some conditions and harmful under other conditions.
C. One variation will always be harmful, and the other will always be beneficial.
D. A single variation can be beneficial in all conditions or harmful in all conditions.
The answer, I do believe, should be option B. Here's my reasoning...
The question doesn't ask about a bunch of other species and how the moth variations relate to the survivability of many species, so I think that rules out option A. Option C is too black-and-white, because the explanation above simply states how a moth was able to survive better on different color variations. The last option, D, is also too black-and-white. So I believe that the answer is B, because sometimes, like prior to the Industrial Revolution, the one variation is better (as seen in the upswing of dominance in different variations).

C. Yes, it will always increase the organism's chances of
survival.
D. Yes, it will always increase the organism's chances of
finding a mate.
Answer:
B
Explanation:
B is the correct answer because the environment effects how the body has to adapt.
A beneficial mutation is not always considered beneficial because: (B) It depends on the organism's environment.
While a beneficial mutation can provide advantages to an organism in certain environments or circumstances, its benefits may not be universal. The suitability of a mutation depends on the specific environmental conditions in which the organism finds itself. Organisms inhabit diverse environments with varying challenges and selective pressures.
A mutation is a change in the DNA sequence of an organism's genetic material. Mutations can occur naturally due to errors during DNA replication or as a result of external factors such as exposure to radiation, chemicals, or certain environmental conditions.
