Suppose you have the following research question: How does low gravity affect an astronaut’s blood pressure? Without actually going into space to find out, what kind of research method should you usee?

A. Experimental Study
B. Observational Study
C. Field Study
D. Simulation

Answers

Answer 1

Answer:

Simulation

Explanation:

In an experiment where you find something out without being there would be a simulation. Hope this helps :)

Answer 2

Without actually going into space to find out, simulation can be used. Thus option D is correct.

What is simulation in research ?

Simulation is the re-enactment of real-world situation for different reason as it cannot be done in real due to several reasons.

This is completely conducted in a controlled environment which also the modification or addition of variable factor if needed.

The primary aim of this technique is to teach people with the appropriate steps to take in the event.

It is mostly used in cardiopulmonary resuscitation (CPR), science  experiments,  movies, sports, and video games.

It is used to identify what type of situation needs to be recreated and assess will be feasible, the goal for doing simulation should be decided, the device, model or parts need to be executed during simulation.

What is the difference between transpiration and diffusion

Answers

Answer:

In sunlight the concentration of water and oxygen molecules just inside the stomata is higher than the concentration of the air around the leaves so water vapor and oxygen diffuse, or move out, from the leaves through the stomata. Diffusion, then, is a physical driver of transpiration. Hope this helps!

Explanation:

In the 1960s the molecular biologist George Streisinger developed the strand- slippage hypothesis. Streisinger noticed that mutations occurred in areas of DNA that contained many repeated sequences. When a strand -slippage occurs, an insertion mutation can result. How does the insertion mutation affect the DNA?

Answers

The insertion mutation affect the DNA by changing certain cells

The insertion mutation affects the DNA cause Nitrogenous bases are added to the mix. This is further explained below.

There are four kinds of tissues in the human body. They are muscle, nervous, connective, and epithelial tissues. Which of the following is true about all of these tissues?

Answers

Answer:  Epithelium tissue refers to the sheets of cells that cover exterior surfaces of the body, lines internal cavities and passageways, and forms certain glands. Connective tissue binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body. Muscle tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart. Nervous tissue is also excitable, allowing the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body

After cooking the hot dogs, your friend's mom reminds you not to leave the grill out, or the iron (Fe) in the grill will react with oxygen (O2) in the air to produce rust (Fe2O3). a. Write a balanced equation for this reaction. Be sure to show your work.

Answers

Answer:

Explanation:

Oxygen gas and water must be present for iron to rust.

A region of the metal’s surface serves as the anode, where oxidation

occurs:

Fe(s) → Fe²⁺ (aq) + 2 e⁻

The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:

O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)

The overall redox reaction is:

2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)

The Fe²⁺ ions formed at the anode are further oxidized by oxygen:

4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)

This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.
