The answer is C- warm air rises and takes the heat with it, eventually it cools and sinks
LekaFEV [45]2 years ago

The correct answer is option C

The convection occurs because of the movement of lighter hot gas that rises up and the dense, cold air that stays below . Due to this heated air eventually replaces the colder air, gets cool down and sinks. This creates an on going process of warming, rising, cooling and then sinking causing the convection current.

Describe three physical characteristics of monerans?
PtichkaEL [24]
No Nucleus

All members of the kingdom Monera have no nuclei in their cells. All genetic material in moneran cells floats loose in the cytoplasm. In fact, the only parts of the cell that exist in a moneran are the cell wall and the ribosomes. Moneran cell walls are made of peptidoglycan. This is the case for all monerans except for archaebacteria. Monerans also move about using flagella.

Digestion

Monerans digest their food outside of the cell and then absorb the nutrients. Different monerans, however, digest their food in a variety of ways. Some simply generate their own food by making their organic compounds. Others need to feed off of other organic matter, such as decaying material. Some monerans are parasites that feed off of a host and others create a symbiotic relationship with another organism. According to Thinkquest.com, monerans are separated into different classifications by how they feed.

Other Characteristics

Monerans reproduce by both sexual conjugation or asexual binary fission. Circulation is done by diffusion, which is similar to the way they digest. Monerans all breathe differently. Some cannot survive without oxygen while some die if exposed to oxygen. Monerans come in three different shapes: spiral, rod-shaped or spherical. In order to protect themselves, most Monerans are surrounded by a capsule of polysaccharides that keeps them from drying out and acts as protection against other harmful cells.

Use the information below to answer the following question(s). In a survey, the rate of heavy smokers was reported as 270 per 10
Eddi Din [679]

The probability that neither of them is a heavy smoker is 0.53 or 53%

<h3>What is genetic probability?</h3>

Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck.

In this case:

Probability that selected one is heavy smoker is:

p=270/1000=0.27

Number of individuals selected  is 2 and We know that:

P(X=x)=nc_x(1-p)^{n-x}(p)^x

We need to prove that X=0:

P(X=0)=nc_0(1-0.27)^{2-0}(0.27)^0

P=0.5329
