A Congressional Budget Office (CBO) estimate put the bill's cost at $182 million over five years when the bill was first introduced in 2016. The policy of the U.S government includes strong support for research into and preparedness for the effects of space weather. Does the government's policy match its actions? Does it match the seriousness of the situation? What are the consequences?
During the Obama Administration, a significant step was taken by the administration in order to prepare critical technology and infrastructure in order to curtail the risk of the space weather.
Space weather simply means the effects that emissions from the sun, have on the space environment. Space weather can have a negative impact on the infrastructures that are essential to the economy like water supply, electrical power, transportation, health care, etc.Space weather is a concern now due to the fact that the modern technology depends on signals and these are vulnerable and can be affected by space weather. The Executive Order was put in place to help in the reduction of economic loss and saving of lives of the people. The policy of the government matches it actions. In order to support the space weather research, it should be noted that National Aeronautics and Space Administration[NASA] keeps an eye and observes the space environment often by using solar observatories and studying the solar atmosphere, magnetic fields etc. and other bodies that surround the Earth.Read related link on:

Explanation:
Viruses and bacteria can infect human cells. Bacteria are living organisms, while viruses are not. How do you think the treatment for viral and bacterial illnesses differ? How do you think they affect healthy body cells? Explain your response.
Answer:
hope it helps
Explanation:
1) antibiotic drugs can kill bacteria however, they are not effective against viruses
2) some bacteria's help to digest foods and speed up enzyme reactions. Some bacteria cells destroy disease causing cells
The treatment for viral and bacterial illnesses differs primarily due to the fundamental differences in their nature and characteristics. Bacteria are living organisms that can be targeted by antibiotics, whereas antiviral medications are used to treat viral infections.
Both bacteria and viruses can affect healthy body cells, with bacteria directly invading cells and causing damage, while viruses rely on host cells for replication and can induce damage during the process.
Bacteria and viruses can both cause damage to host cells. Bacteria can directly invade and damage cells through mechanisms such as releasing toxins or inducing inflammation.
Viruses require host cells to reproduce. They invade host cells, hijack cellular machinery to replicate themselves, and subsequently cause damage to the infected cells during the process.

A person lives on the Tropic of Capricorn. What is the altitude of Polaris?
O 23 1/2"
O 90°
O 66° 33"
O 15°
O 30°
O 45°
The correct answer as to what the altitude of Polaris would be for a person that lives on the Tropic of Capricon is 23° 1/2".
Polaris is a star and the altitude of any star is its height above the horizonThe Polaris is otherwise known as the North star as an indication that it is directly located overhead the north pole. Thus, it may not be visible once one moves South of the equator. The tropic of Capricon is located approximately 23° 1/2" South of the equator. In other words, the latitude of the Tropic of cancer is approximately 23° 1/2".Hence, the altitude of the Polaris at an altitude of 23° 1/2" will also be 23° 1/2", although it will most likely remain invisible.A person that lives on the Tropic of Capricon is approximately on latitude 23° 1/2". Since the altitude of a star is its height above the horizon, the altitude of Polaris from the Tropic of Capricon would, therefore, be 23° 1/2"

--------------------------------------
During an experiment, you need to consider all the variables involved.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified to analyze how another variable responds to it. The researcher changes the independent variable to observe its effects on the dependent variable. Usually, the independent variable is represented by the X letter. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. Controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.
1. Endurance in high altitude mountain climbers with and without the use of supplemental O2.
a. Independent Variable: supplemental O2
b. Dependent Variable: Endurance in mountain climbers
The endurance of climbers will depend on the use of supplemental O₂. If they use supplemental oxygen, they will have more resistance than if they do not use it. Supplemental Oxygen is influencing the climbers´ endurance.
2. Weight loss in subjects eating low carbohydrate diets.
a. Independent Variable: low carbohydrate diets
b. Dependent Variable: Weight loss
Having a low carbohydrate diet will lead the subjects to lose weight. Any change in the quantity of the carbohydrate will affect the individuals' weight.
3. The number of hours spent studying biology each week and grades earned on biology exams.
a. Independent Variable: hours spent studying biology
b. Dependent Variable: grades earned on exams
The more hours students spend studying, the higher grades they get on biology exams. The grades depend on the number of hours used to study and are proportional to this variable.
4. Cancer rates in students who smoke cigarettes are closely monitored over a 5-year period.
Control Group: Time → Five years
Time is constant in all the study groups. Independently of the number of cigarettes smoked, or the frequency in which subjects smoke, all the groups will be analyzed for 5 years, and this time-lapse is constant.
5.Weightlifters are given 400 mg of creatine phosphate every day for 90 days. At the end of the 90-day period each participant is evaluated for improvements in strength.
Control Group: Time → 90 days
Time is constant in all the study groups. Independently of the creatine phosphate mg provided to weightlifters, individuals will be analyzed for 90 days, and this time-lapse is constant.

(1) Response to stimuli: Does the entity sense and respond to environmental change?
They just can reproduce when they are in the host
Answer:
Organisms need to detect and respond to changes in their internal and external environment. This is because the conditions inside our body must be carefully controlled for it to function effectively and survive. The control systems that allow organisms to respond to changes are incredibly important.
All control systems include:
Cells called receptors, which detect stimuli (changes in the environment).
The coordination centre, such as the brain, spinal cord or pancreas, which receives and processes information from receptors around the body.
Effectors which bring about responses, and restore optimum levels, such as core body temperature and blood glucose levels. Effectors include muscles and glands, and so responses can include muscle contractions or hormone release
