Answer:
Killing pathogens and then using them to provide the body with active immunity is called IMMUNIZATION . This is often done in young children.
When the immune system treats otherwise harmless substances, such as pollen, as if they were invaders, a/n ALLERGY can occur.
HIV is a virus that attacks WHITE BLOOD CELLS in the body, weakening the immune system.
Polio used to be fairly common and devastating. Thanks to widespread vaccination against polio, the disease is now considered ABSENT, no longer infecting nearly as many people as it once did.
Arthritis is an example of a/n AUTOIMMUNE DISORDER where part of a person’s body is identified as foreign and attacked by the person’s immune system.
Immunization helps involves the injection of dead pathogens into the bloodstream. This helps in the release of antibodies which helps in protecting the body against further attacks in the future.
Allergy happens as a result of the body system treating and attacking harmless substances.
This is because the ships which brought immigrants into the country had someone who had small pox on board which spread and many got infected and killed due to lack of vaccine and treatment.
Immunization helps people to travel without having to worry about diseases.
Answer:
vaccination
allergic reaction
t-cells
eradicated
autoimmune disease
Europeans had been exposed to the virus that causes smallpox for many generations, allowing them to acquire immunity to the virus. Native Americans were not exposed to smallpox or similar viruses before, so they had no immunity to the virus. In modern times, before traveling abroad, a person often receives vaccinations or other medications to avoid contracting the diseases specific to that region of the world.
Explanation:
If one strand of DNA double helix has the following nucleotide sequence ATCGGTCAAGCTAGG what would the dna complementary stand read
Answer:
TAGCCAGTTCGATCC
Explanation:
In DNA, there are 4 different nucleotide bases. Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).
A (adenine) always pairs with T(thymine) and C(cytosine) always pairs with G (guanine).
If we have the strand:
ATCGGTCAAGCTAGG
We have to pair A with T, and C with G. Therefore, the complementary strand of DNA will be:
TAGCCAGTTCGATCC

The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Yellow pods are the dominant trait. The flowchart is missing the labels that describe the traits. A flow chart is shown. A and B both go to C. C goes to both D and E.
Hello. This question is incomplete. Also, you forgot to show the flowchart. The flowchart is attached below and the full question is:
The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Green pods are the dominant trait. The flowchart is missing the labels that describe the traits.
In which squares should the phrase “Green pods” appear?
1.A and D 2.B and E 3.A,C and D 4.A,B,C,D and E
Answer:
3.A,C and D
Explanation:
As shown in the question above, the flowchart shows the crossing of a pea plant with dominant features (green pods - AA) and a pea plant with recessive features (yellow features - aa). The crossing between plants with AA and aa alleles generates a completely Aa population, which in this case, has the dominant characteristic, that is, it has green pods. This is because the "Aa" alleles are called heterozygous and develop the dominant characteristic.
As we can see in the flowchart, the crossing between the two pea plants generated an offspring that is identified by table C, as we know this offspring has green pods and in the flowchart it is represented by a grayish rectangle. Therefore, we can say that the other gray rectangles represent pea plants with green pods, which are rectangles A, C and D.

An important example of a "positive feedback loop" in the polar climate system is:
a.Scientists in remote places check on each others instruments.
b.Warming ocean water opens new areas for marine species.
c.Warmer winters cause more plant growth, providing more food.
d.Sea ice melt opens more ocean to sunlight, causing more melt.
Answer: D
Explanation:
A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction.
In choice D melting of sea ice opens more ocean to sunlight which causes more ice to melt which demonstrated a positive feedback loop.
The significant example of a positive feedback loop in the climate system i.e. polar should be at the time when the ice of the sea should be melt that there should be more ocean that results in more melting.
The following information related to the positive feedback loop is:
If the direction varies so it should result in an extra change in a similar direction.Like if we take an example that if there is an increase in the substance concentration so it results in the feedback that generated the continued increase in the concentration.Therefore we can conclude that option d is correct.
All other options seem incorrect.

A medical test indicates that a patient has a defective protein. This
condition is most likely due to a change in the directions coded in the:
number of phosphate molecules
sequence of subunits in DNA
number of nitrogen bases
sequence of sugar molecules
Answer:
number of nitrogen bases
Explanation:
The correct answer would be the number of nitrogen bases.
A defective protein is usually caused by mutation, which is defined a change in the DNA sequence of an organism.
Mutation can occur in a variety of ways including:
1. Deletion of nucleotide base sequence in the DNA
2. Addition (insertion) of nucleotide base sequence in the DNA
3. Duplication of nucleotide sequence in the DNA
A change in number of phosphate molecules, sequence of subunits DNA and sequence of sugar molecules if possible in nature, do not lead to mutation if the change does not affect the sequence of DNA.
Hence, the correct option is number of nitrogen bases.

you are given a quadrat of 1.5 square meters and you count the
dandelions in 10 quadrats and find an average of 2 dandelions per quadrat
area. Use this information to estimate the population density of dandelions
per square meter in a 4500 square meter open field. (make your answer
just the number, round to the nearest 2 decimal places) *
Your answer
In a stable population of rabbits and wolves a government agency enacts a 1 point
Answer:
1.33 dandelions per square meters
Explanation:
The correct answer would be 1.33 dandelions per square meter of land.
Size of quadrat = 1.5 square meters
Average number of dandelions per quadrat = 2
Total study area = 4500 square meter
Population density = number of organisms per unit area
There were 2 dandelions per 1.5 square meters
How many would be per square meter?
= 2 x 1/1.5 = 1.3333 dandelion per square meters
To 2 decimal places = 1.33 per square meters

Why does light from the sun melt the plastic when light from the desk lamp does not
Answer:
Because the sun gives off a type of light that carries energy, and light from the desk lamp does not.
Explanation:
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
Lamps are electrical devices that use electrical energy in the form of electrical current.

Answer:
FOG stands for 'fats, oils and grease'. It is present infood products such as lard, butter, animal fats, vegetable oils, and dairy products.
FOG is prepared during the process of cooking and the washing up processes. When FOG is allowed n sewer pipes it can accumulates inside sewer pipes, so proper disposal method of FOG is required.
Some of the source of FOG and disposal methods are as following:
Cooking oil - Allow the oil to be cooled and place it in a non-recyclable container such as plastic-lined paper containers.
Food Scraps: compost bin can be used to dispose FOG by putting all food scrap into it.
Salad dressing - If little maount of salad dressing is left, use a paper towel to clean it and it will absorb the left residue which can be easily dipose in garbage.
Dairy products such as milk - it can be disposed on-farm or to a proper disposal site otherwise it will affect groundsurface as it contain fat.
Hence, using above methods for disposing FOG will help to save envrionment.

Genetic drift and natural selection can both be mechanisms of evolution. However, they are very different mechanisms. Explain how genetic drift is different from natural selectio
Answer:
Explanation:
Natural selection is the survival of individual organism due to the difference in phenotype. It serves as a basic for evolution as the different heritable characteristics in an individual is due to natural selection. Natural selection acts on the phenotype of the individual which is the visual observance while Genetic drift is the change in frequency of an allele that already exist in a population. This could lead to the allele being selected against and if very small can be lost with time.
