A young woman was going on a walk through the woods when she felt a mosquito bite her. She has a history of large local reactions to mosquito bites in the past. The reactions have been so severe she has even been skin tested, but the test came out negative. After the most recent bite, she went back to the doctor complaining of swelling at the site, dizziness, headache, and nausea. Benadryl is able to help relieve some symptoms. The doctor decides to try a blood test (i.e. ELISA based test) instead to test for allergies.

Required:
a. What is an ELISA test and how is it done?
b. Which antibody would they be looking for specific in this case?
c. The doctors also ran an SDS-PAGE test using the patient's serum mixed with two different antigens: lane 1 - bee venom; lane 2 - mosquito venom. What do the results show regarding the patient’s allergies?
d. Why are there two dark blue bands in lane 2?
e. Describe what happens during this specific type of allergic reaction.

HELP!!! Im doing an honors assignment for science class on space weather! I dont need you to do it I just need someone to help me understand it!

here are the instructions:

Advanced Space Weather Activity
This lesson highlighted different types of space weather. If you were responsible for reporting space weather like Earth's weather is reported, how would you do it? What would you include?

Create any type of weather report to warn people about space weather activity. You can present it like a weather app, radio announcement, television news report, or newspaper weather section. You only need to pick one type of report to submit to your instructor.

They gave an example below however im confused if I should copy it and put my own words or if I should just make like a video or something!

please help me :(

Answers

Answer:

If I was responsible for earth weather, I would do this:

People watch TV every day. No? Well. some do! I would create something better than amber alerts, something better than the news on TV. I would put earth's loudest megaphones in every single state. One in every city. About 670,000,000,000 in total! It would tell people all around the world what the news up in space is ! For backup, I would also use a weather app but for space. People are on their phones everyday. Lets make it useful! The space weather app would tell people everyday what the weather is up in space, making them interested in space weather! For instance, Over at Mars, its currently 35° degrees! Many people are interested in space, let them know the weather of their favorite planets ! Make a channel on TV ! Hope this helps <3

The energy of the sun heats the land unevenly, creating wind.

What is Earth?

Earth, the third planet from the Sun, is the planet where all known life is found. Although the Solar System contains enormous amounts of water, only Earth is home to liquid surface water.

The ocean covers roughly 70.8% of Earth's surface, dwarfing the polar ice, lakes, and rivers. Earth's surface is made up of continents and islands for the remaining 29.2% of its total area.

Several slowly moving tectonic plates that make up the Earth's surface combine to create mountain ranges, volcanoes, and earthquakes. The magnetic field that forms the Earth's magnetosphere and diverts harmful solar winds is produced by the liquid outer core of the planet.

Therefore, The energy of the sun heats the land unevenly, creating wind.

A: Increase cellular respiration and ATP production
B:Estivate with a period of dormancy until the warmer weather arrives
C:Migrate to regions of warmer weather
D:Slow down its metabolic rate and lower its body temperature

Answers

Answer: cccccccc

Explanation:

Answer:

I think the answer should be B, because skunk doesn't migrate or hibernate, and A doesn't make sense because when animal facing temperature drop and food shortage they do not speed up metabolic process, instead they will slowdown the metabolic process and save as much energy as possible.

What type of reaction does catalase facilitate- synthesis or decomposition? Why?

Answers

Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.

Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.

What is catalase?

An enzyme called catalase causes (catalyzes) the process by which hydrogen peroxide is broken down into water and oxygen.

Catalase, which is widely distributed in organisms that live in the presence of oxygen, inhibits the buildup of peroxide, which is continuously created by multiple metabolic reactions, and shields cellular organelles and tissues from harm. Catalase is primarily found in the liver of mammals.

Numerous industrial uses exist for catalase. It is used with other enzymes in the food industry to preserve foods, make particular dishes and beverages, and preserve foodstuffs.

Therefore, Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.

The correct answer is - Trains can have inconvenient schedules, but produce less pollution than cars do.

Explanation:

Trains are expensive to build and also required land for making routes and stations and platforms for passengers but that can be reimbursed by fare in a longer time period.

Which of the following is not a characteristic of enzymes?
Each is used to break down substances.
Each has a specific substrate.
Each has an optimal temperature and pH.
O
Each has an active site.

Answers

Answer:

Each is used to break down substances.

Explanation:

Enzymes merely speed up a chemical reaction, not necessarily break down substances.

Each enzyme is used to break down substances is not a characteristic of enzymes. The correct option is A.

Thus, enzymes aren't just utilized to degrade things. Enzymes perform additional crucial tasks in addition to being essential for the breakdown (catabolism) of substances. In living things, enzymes operate as biological catalysts to quicken chemical processes.

Enzymes achieve this by reducing the activation energy needed for a reaction to happen and thereby speeding up the reaction rate. While some enzymes are engaged in the breakdown of chemicals, others are involved in the synthesis or modification of other molecules (anabolism).

Thus, the ideal selection is option A.

To us as a people it has been granted to lay the foundations ofour national life in a new continent. We are the helrs of the ages, and yet we have had to pay few of the penalties which in old countries are exacted by the dead hand of a bygone civilization. We .have not been obliged to fight for our existence against any allen race; and yet our life has called for the vigor and effort without which the manlier and hardier virtues wither away. Under suchconditions it wouldbe our own fault if we falled; and the success which we have had in the past, the success which we confidently belleve the future will bring, should cause in us no feeling of(vanity), but rather a deep and abiding realization of all which life has offered us; a full acknowledgment of the responsibility which is ours; and a fixed determination to show that under a freegovernment a mighty people can thrive best, allke as regards the things of the body and the things of the soul.Much has been given us, and much will rightfully be expected from us.
