In an experiment you, the researcher, remove atp from the system. what would be a likely consequence of the lack of atp on muscle contraction?

Answers

Answer 1
Answer: The tropomyosin filament would not be dislodged preventing contraction.

The cross bridges would remain linked and therefore contraction would stop

The cross bridges would break apart due to the presence of calcium ions enabling some contraction

The myosin heads would separate from the actin molecule due to the release of ADP that was previously present.

1.ATP hydrolysis 

2.Detachment of myosin head from actin

3.Power stroke

4.Crossbridge formation

Analyze the document "King Andrew the First (c. 1833)” by explaining its "HIPP” (historical context, intended audience, author’s purpose, and author’s point of view). Refer to elements in the image to explain your response.

Answers

The analysis of the document "King Andrew the First (c. 1833)” is as follows:

Historical context

  • It was created during the 1833 removal order

Intended audience

  • The American public

Author's purpose

  • To show that people truly believed in him

Author's point of view

  • First person

President Andrew Jackson was an enigmatic and strong personality during his tenure as President of the United States of America.

As a result of this, there was a cartoon which was created to help further his agenda. In it, he is depicted holding a veto power on top of the Constitution, while dressed in royal attire.

He wanted to show that he was a man of the people but it was viewed as a person who was wielding too much power than was suitable for a president as he occasionally acted without congressional approval.

Answer: Andrew Jackson was a strong president. He used the office to forcefully pursue his agenda. This cartoon is quite famous, coming out around 1833, because of the 1833 removal order. In the cartoon, the president can be seen holding a veto in his hand, and standing on top of the Constitution. He is dressed up as a king, holding - perhaps - too much power. I believe that the intended audience was the people. The people saw him as a king, abusing his powers as a president. The author’s purpose was to show how people truly viewed him. The president’s order to remove federal deposits from the Bank of the United States led to an increase in state debt. The President was strongly criticized because he acted without congressional approval, as a king would.

Explain solar flares and how it affect earth

Answers

A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots. Flares are our solar system’s largest explosive events. They are seen as bright areas on the sun and they can last from minutes to hours. We typically see a solar flare by the photons (or light) it releases, at most every wavelength of the spectrum. The primary ways we monitor flares are in x-rays and optical light. Flares are also sites where particles (electrons, protons, and heavier particles) are accelerated.
Solar flares impact Earth only when they occur on the side of the sun facing Earth. Because flares are made of photons, they travel out directly from the flare site, so if we can see the flare, we can be impacted by it.Coronal mass ejections, also called CMEs, are large clouds of plasma and magnetic field that erupt from the sun. These clouds can erupt in any direction, and then continue on in that direction, plowing right through the solar wind. Only when the cloud is aimed at Earth will the CME hit Earth and therefore cause impacts.

The cardiovascular system is also known as the ________.

Answers

The cardiovascular system is also known as the circulatory system.

It is made up of the heart, the blood vessels namely arteries, veins and capillaries, and approximately five liters of blood.

The circulatory system's major functions are to transport  oxygen, hormones, and nutrients to every cell in the body, and to tale away cellular waste products from the cells such as carbon dioxide  and bring them to excretory organs  where they are expelled out of the body.

The circulatory system is kept running by the heart, which is a muscular organ the size of the closed fist of an adult. It pumps about 5 liters of  blood every minute throughout the body.

Final answer:

The cardiovascular system is also known as the circulatory system. It delivers oxygen and nutrients to tissues and helps regulate body temperature.

In which sealed container would the organisms be able to continuously cycle O2 and CO2 gases?A. A terrarium with mice and wood shavings
B. An aquarium with fish and plastic plants
C. An aquarium with water plants and a snail
D. A terrarium with a frog and a pool of water

Answers

The correct answer is C.
In the aquarium, the water plants would provide the O2 molecules necessary for the snail's metabolism and the snail would release the CO2 molecules that are a byproduct of his metabolism into the container. The CO2 would later be used by plants to make sugar in the process of photosynthesis, releasing more O2 and the cycle of two gases would be completed.

Answer:

The correct answer is C. An aquarium with water plants and a snail

Explanation:

In an aquarium with water plants and snail the flow of oxygen and carbon dioxide will be continuous because plants are able to do photosynthesis which release the oxygen as the byproduct and this oxygen will be used by snail and snail during respiration release CO2 which will be used by plants in the process of photosynthesis to make food for itself.

Therefore there will be symbiotic relationship between plants and snail because snail provides carbon dioxide to plant and plant provide oxygen to the snail and support their survival. Therefore in this container organism would be able to continuously cycle O2 and CO2. So the right answer is C.

Ozone is both helpful and harmful to life on Earth.
