convention cells hbnmb,

Answers

Answer:

convention cells

Explanation:

In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas. These density differences result in rising and/or falling currents, which are the key characteristics of a convection cell. When a volume of fluid is heated, it expands and becomes less dense and thus more buoyant than the surrounding fluid. The colder, denser part of the fluid descends to settle below the warmer, less-dense fluid, and this causes the warmer fluid to rise. Such movement is called convection, and the moving body of liquid is referred to as a convection cell. This particular type of convection, where a horizontal layer of fluid is heated from below, is known as Rayleigh–Bénard convection. Convection usually requires a gravitational field, but in microgravity experiments, thermal convection has been observed without gravitational effects.

Which of the following is the most susceptible to damage by pollution in the air and
precipitation

A. The roots of trees
B. Trees at high elevations
C. Birds that migrate seasonally
D. Plants that grow in lakes or rivers

Answers

Answer:

B) Trees at high elevations

Explanation:

The atmospheric conditions and precipitation toxicity is most likely to affect trees at high elevations more so than the other answers.

The tree leaves, which are the main key to the tree's photosynthesis, absorb the oxygen and Co2 from the air, which are converted into nutrients. Without proper nutrients, the trees may die out.

The cell membrane consists of ONE layer of phospholipids.

A. True
B. False​

Answers

Answer:  Hi there I think That I can help You!!!

The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable. Part of the cell membrane is a phospholipid bilayer, made of two layers of phospholipid molecules. However, the cell membrane also contains other macromolecules like membrane proteins, and carbohydrates.

Explanation: So the correct answer is TRUE! don't forget to ate 5 stars and give brainlist!

The statement "the cell membrane consists of one layer of phospholipids" is absolutely false.

What is a Cell membrane?

A Cell membrane may be defined as a type of biological membrane that significantly separates the interior components of the cells from the external environment. It also provides protection to the cell as well as other cell organelles.

A cell membrane is made up of a phospholipid bilayer. This illustrates that the two layers of phospholipid molecules are utilized in order to make an effective cell membrane.

It acts as selectively permeable in nature. The head or polar region of phospholipid is hydrophilic while the non-polar tail is hydrophobic in nature.

Therefore, the statement "the cell membrane consists of one layer of phospholipids" is absolutely false.

Both microscopy and motility agar are used to confirm microbial mobility. Research techniques involving microscopic determination of mobility and explain why both microscopy and motility agar are required to determine motility in some microbes.

Answers

Answer:

One allows microbe to move in the medium and the other allows to see it.

Explanation:

Both microscopy and motility agar are required to determine motility in some microbes because both substances helps to find out the mobility in the microbes. Motility agar is the medium that allows microbes to swim if they have flagella in their body while on the other hand, microscope is used to see the movement of microbes in motility agar. Microbes are small creature which can't be seen through naked eyes so we used microscope for it.

A very common dahlia plant with red petals is crossed with another very common plant having streaky petals. The probability that an offspring from this cross has red flowers is .75. Let X be the number of plants with red flowers grown from 100 randomly collected seeds from a very large population (N > 10,000) of this cross. A. Does the random variable X have a binomial distribution

Answers

Answer:

Yes, it is vivid that the random variable has a binomial distribution

Explanation:

From the given information:

The probability of the plant with red flowers(p success) = 0.75

the sample size n = 100

Thus, the mean μ = np

= 100 ×0.75

= 75

The standard deviation can be calculated by using the formula:

[tex]SD = \sqrt{np(1-p)}[/tex]

[tex]SD = \sqrt{100 \times 0.75(1-0.75)}[/tex]

[tex]SD = \sqrt{100 \times 0.75(0.25)}[/tex]

[tex]SD = \sqrt{18.75}[/tex]

SD = 4.33
