No. Scientists have never predicted a earthquake. We do not know how, and we do not expect to know how any time in the foreseeable future.
Answer:
The vascular system
Explanation:
The human blood circularitory system can be used to explain capillary action in the human body, our heart pumps blood in and out with no use of external forces.
The sexual reproduction helps in having more variation among the offsprings. It also makes the offsprings more resistant to genetic diseases.
<h3><u>Explanation</u>:</h3>
Sexual reproduction is the process by which the gametes of the species fused together to form zygote which develops into an offspring. This offspring produced has the gene from both the parents . This genetic setup is not only copied from the parents but they undergo the crossing over and independent assortment which leads to variation among the offspring itself as well as they differ from their parents too.
This variation among the offspring as well as the crossing over helps to eleminate the lethal genes from the genetic pool. Thereby they help to get more resistance among the offsprings from diseases.
Answer:
The following might explain the lack of cloud formation
- The air package never reaches its dew point.
- There are too few aerosols present in the air package.
<u>Explanation</u>:
For the formation of the cloud the air in the higher position should have much colder than that of the surface. The vapours travels till it reaches the point where it has lower temperature as well as the pressure so that the water will condense into the droplets which will result in the formation of the cloud. When those vapours condenses to the liquid or to the solid it will release some of it energy to the air. For the formation of the cloud three things are mandatory and they are moisture, cooling air and the condensation nuclei. Also, for the formation of clouds, suspended particles like aerosols are required for the water to condense. As there are few aerosols, water doesn't get to condense.
