a warming global climate can create hot and dry regions. it can also contribute to natural CO2 emissions. For example, lighting
strikes in a dry forest region can cause ___. a. volcanoes b. wildfires c. acid rain The added CO2 from this event results in a positive feedback loop, increasing heat in the atmosphere as it ___. a. supports photosynthesis b. magnified the greenhouse effect c. escapes into space
The first blank is pretty simple; if lightning (electricity) strikes something flammable, like a forest, a fire is sure to ensue. This fire will obviously spread to the other trees and cause a massive wildfire.
The second blank is the greenhouse effect. The greenhouse effect is said to have caused our warming climate, which makes sense because heat from the sun gets trapped in our global "greenhouse", or the lower atmosphere. Lower atmosphere is key here because a large event like a massive wildfire can add some more heat to the atmosphere and contribute to this effect. A wildfire may seem like a minor event on a global scale, but it will do more damage to the atmosphere than you think!
It refers to making or crating new genes in form of mutation
in duplicates of old genes. It is also a mechanism in major way through new
genetic material is generated during evolution. The duplication happens in
event termed unequal crossing over or recombination between misaligned
homologous chromosomes during meiosis.
well i only know that a male has 23 chromosomes and his hormones are called testosterone ,please follow me and his sex chromosome is <em><u>xy</u></em>
