Which state of matter is least likely to transfer heat by convection?solid

liquid

gas

plasma

Answers

Answer: Liquid

Explanation:

Liquid and gases are fluids as they can flow. Convection takes place when the the particles having more energy is replaced with the particles having less energy.

The hotter particles moves and takes place of the colder particles when a liquid is heated. The liquid that lies in the hotter region is less dense than the colder regions. So, less dense particles move to replace the more dense particles.

Bones provide both structure and protection for the body. Please select the best answer from the choices provided.a. True
b. False

Answers

Bones provide both structure and protection for the body is absolutely true. Bones or your skeleton protects all the organs in your body.

Final answer:

Bones provide structure and protection for the body, they work with muscles and joints to allow movement and protect various organs. Therefore, the correct answer is True.

Explanation:

The statement that bones provide both structure and protection for the body is True. Bones provide structure by working together with muscles and joints to allow movement. Bones also protect the body's various organs. For example, your skull protects your brain, your rib cage protects your heart and lungs, and your spine protects your spinal cord.

The function f(t) = 4t2 - 8t + 6 shows the height from the ground f(t), in meters, of a roller coaster car at different times t. Write f(t) in the vertex form a(x - h)2 + k, where a, h, and k are integers, and interpret the vertex of f(t). A. f(t) = 4(t - 1)2 + 3; the minimum height of the roller coaster is 3 meters from the ground

B. f(t) = 4(t - 1)2 + 3; the minimum height of the roller coaster is 1 meter from the ground

C. f(t) = 4(t - 1)2 + 2; the minimum height of the roller coaster is 2 meters from the ground

D. f(t) = 4(t - 1)2 + 2; the minimum height of the roller coaster is 1 meter from the ground

Answers

f(t) = $4 t^(2) -8+6$
The formula to use is: a(x-xv)^2+yv
where a is the coeficient of x^2, xv= -b/2a (b is the coeficient of x) and yv= -delta/4a or f(xv)

xv = 8/8 =1
yv = f(xv)=f(1) = 2

f(t) = 4(t-1)^2+2 the minimum value is 2 when t=1

The answer to your question is C. I hope this is the answer that you are looking for and it comes to your help.

The function f(t)can be written in the vertex form as: C. f(t) = 4(t - 1)² + 2; the minimum height of the roller coaster is 2 meters from the ground.

How to write this function in vertex form?

Since the leading coefficient in the given function f(t) is positive 4, the parabola will open upward and at the vertex. Also, the value of the function f(t) would be minimum.

Evaluating the function by applying completing the square, we have:

f(t) = 4t² - 8t + 6

f(t) = 4(t² - 2t) + 6

f(t) = 4(t² - (2 × t × 1) + 1² - 1²) + 6

f(t) = 4(t² - (2 × t × 1) + 1² - 1) + 6

f(t) = 4(t² - 2t + 1²) - 4 + 6

f(t) = 4(t² - 2t + 1²) + 2

f(t) = 4(t - 1)² + 2.

Therefore, the vertex of f(t) will be at (1, 2) and the minimum height of the roller coaster is 2 meters from the ground.

A biology student is studying ways to grow crops in soils that are high in salts and other dissolved solids. To determine whether corn plants can tolerate salty soil conditions, she grows one corn plant in typical non salty soil and one corn plant in the same soil plus 0.5 kilograms of salt. after 6 weeks of growth, the corn plant grown in salty soil is only about 50% of the mass and height of the corn plant grown in non-salty soil. How can this research be improved so that she will have greater confidence in her data?

Answers

Repeat the experiment but with additional corn plants to increase the sample size will result in greater confidence in her data.

What is Data?

Every cell in the human body contains the same set of instructions. Why is it that some cells are muscle cells, some cells are nerve cells, and other cells are skin cells?

Answers

Answer:

Different genes are expressed in different cells

Explanation:

The instruction is provided to the cell by the genetic material in the form of genes. Genes are the physical segment present on the DNA which can code for a specific protein.

The genes are present in the cells in the condensed form called chromosome which is present in all the cells of the body.

Although all the cells contain the same type of chromosomes or genes but they differentiate to perform different functions.

The differentiation process involves the expression of different genes in different cells as a result of which different proteins are formed in different cells and they perform different functions.

Every cell in the human body contains the same set of instructions. Why is it that some cells are muscle cells, some cells are nerve cells, and other cells are skin cells? Different genes are expressed in different cell types. ... Cell division is necessary to support life.
