A farmer produces two types of corn plants. One has larger sized kernels but fewer yields and another has smaller sized kernels
with high yield. He wants to produce a corn plant with larger sized kernels with high yield. Which of these methods would be applicable for this?
A. Eliminate the gene for lesser yield from the genome of larger sized kernels and eliminate the gene for smaller sized kernels from the other corn variety.
B. Insert the genome responsible for larger sized kernels into the gene of the corn with smaller sized kernels and a high yield.
C. Insert the gene responsible for larger sized kernels into the genome of the corn with smaller sized kernels and a high yield.
<span>If the farmer chooses option A, he is merely left with two types of corn that produce no yield at all, because in the one instance he will eliminate the gene that produces yield and in the second plant it will produce no kernels because the gene is eliminated. It is impossible to insert an entire genome into the genetic material of another organism. The genome is the entire genetic data of an organism, including junk DNA etc, so option B is out. The best way to do it is to genetically introduce the gene for larger sized kernels into the corn plant that produces higher yields using molecular cloning techniques. So the correct answer is C.</span><span />
Because, without them, the dead animal will just sit there. So, having decomposers gets rid of the remains of the animal, and that way they can eat too. Hope it helps good luck!
The rate of energy coming from the Sun changes slightly day to day. .It has been suggested that changes in solar output might affect our climate—both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes.
The axial tilt angle affects climate largely by determining which parts of the earth get more sunlight during different stages of the year Likewise, during winter for the northern hemisphere, there would be fewer hours of daylight because the northern hemisphere would essentially be pointed away from the sun.
If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere, blocking the radiation from the Sun. This would cause the global temperature to decrease drastically.
The Sun's irradiance has its greatest effect on Earth's upper atmosphere, while the lower atmosphere insulates Earth from the increased heat. If the Sun were driving Earth's warming, one would expect to see that upper atmosphere getting increasingly hot.\
