A third mode of heat transfer from a warmer to a colder body is thermal radiation. Unlike the other two processes, conduction and convection, irradiation allows heat transfer, or radiant heat. Heat waves from the sun travel a great distance in a vacuum until they reach Earth and transfer heat to it from the sun.
Scientists have observed elephant reactions to stressful situations. Animals are able to calm each other down, according to study. Asian elephants are able to comfort and soothe each other with physical contact and vocalizations in times of distress, according to the findings of a study published February 18, 2014 by PeerJ magazine.
Not all traits are inherited as the pea seed color, where the yellow color gene dominates over the green color gene. Very often, the combination of the different allele genes produces an intermediate phenotype. This situation illustrates the so-called incomplete or partial dominance.
Being giant doesn't necessarily mean being easy to see. Some of nature's largest animals behave shyly or know how to camouflage very well, remaining mysterious to scientists. Check out ten of them that are rarely seen: Armadillo (Priodontes maximus) In theory, it seems easy to spot something the size of a pig, covered with scales and with claws up to 20 centimeters similar to a small sword.
Soil is a part of the biosphere usually full of life. Many of the living things that inhabit the interior of the ground are not visible to the naked eye, but there are others that can be easily seen. An example is the worm. It lives in moist soil, as it is usually the fertile soil that serves as a flower bed (garden or garden).
Let us now briefly describe two important diseases related to the action of “defective” genes. Phenylketonuria Phenylketonuria (PKU) is a genetic disease due to the action of a recessive gene that manifests in homozygosis, affecting approximately 1 in 12,000 newborns in Brazil.
