Answer:
Those three are extremely related.Humus is the organic matter that forms in the soil when plant and animal matter decays. It is basicaly the part where the soil is more moistured and receives more nutrients. microoroganisms are present in the matter of plants and anumals and they are very important for the sustainability of the soil. Humus contains many useful nutrients for healthy soil, like nitrogen, which assures the proper health of it.

extinction because of a fungus. The fungus, called white-nose syndrome, grows on the
exposed skin of bats as they hibernate in cool caves or mines. Infected bats develop lesions
(sores) on their wings, which play important roles in water balance, circulation and heat regulation.
These lesions on a bat’s wings or on its nose cause the bat to wake up during hibernation.
Waking up early forces the bat to use up the energy it has stored as fat for its long
sleep, exhausting the animal and eventually killing it.
In some infected caves, 90 percent to 100 percent of bats die. On average, the disease
takes out 73 percent of the bat population at a given hibernation site. If infection continues
at current rates, the researchers predict that the little brown bat population will drop below
0.01 percent of its current numbers by 2026.
The loss of the little brown bat would be harmful for humans because bats eat their
body weight in insects each night. Many of these bugs are agricultural pests or carriers of
human disease.
One way to decrease the spread of the disease would be for the researchers who visit
infected caves to decontaminate their clothes and gear with antiseptics. It has also been suggested
that a small number of these bats could be placed in an artificial hibernating area
and medicated to protect them.
Describe one way that an infection with the white-nose fungus can cause death in little brown bats.
The correct answer is option D
Reflections from the surface warm the atmosphere.
Reason -Radiation is the process by which the earth radiates the heat absorbed by it during the day time. The earth absorbs the solar radiation during the day time and gets heated , during evening the earth emits the heat in the form of reflections i.e radiation due to which the hearth gets further heated up.
b. . a polygenic trait that is influenced by the number of alleles present
c. . a codominant trait that is expressed more often when more dominant alleles are present
d. . a dominant trait that depends on the presence of only one of many dominant alleles
The answer is b. a polygenic trait that is influenced by the number of alleles present.
There are three genes linked to a common form of glaucoma, so it must be the polygenic (meaning more than one gene included) trait. The polygenic traits are influenced by the number of alleles. In this case, there are more than 20 genetic loci which means there must be a great number of alleles for all loci.
Meiosis II typically produces four cells, each of which is haploid.
Haploid cells contain half the number of chromosomes as the original cell and are used in sexual reproduction to form a new organism with unique genetic information.
During meiosis II, the two daughter cells produced from meiosis I undergo another round of cell division, resulting in four haploid cells. These haploid cells are then used in fertilization to form a zygote with the full complement of chromosomes.
