Answer:
It is expected to observe a low genetic variation within populations and high genetic variation between populations.
Explanation:
The pika's populations are geographically isolated among them, it drastically will increase the genetic variation among populations, especially due to the random process of genetic drift (and also to mutations). On the other hand, this geographical isolation also contributes to decreasing the genetic variation within populations due to the endogamy among their members. The combination of both genetic features (i.e., a low genetic variation within populations and high genetic variation between populations) are expected to produce high genetic diversity effects and a low population structure.
Debido a que el hidrógeno molecular expulsado por los volcanes se difundió en el espacio, la Tierra ganó una atmósfera rica en oxígeno. Otra posibilidad es que el oxígeno se acumule debido a una disminución de gases – como el hidrógeno – que reaccionan con y por lo tanto "absorben" el oxígeno.

Answer:
The correct answer is "II. peroxisomes, I. mitochondria, and III. lysosomes".
Explanation:
The differences in organelles density are utilized for purification purposes, creating density gradients that helps to isolate each organelle separately. The correct order of organelles from most dense to least dense is: peroxisomes, mitochondria, and lysosomes. Peroxisomes have a density of around 1.19 g/ml, mitochondria of around 1.07 g/ml, and lysosomes of around 1.04 g/ml.
When a single cell undergoes many mitotic divisions in the nucleus, producing many daughter cells, it has conducted B) Multiple fission.
Multiple Fission is a type of asexual reproduction in which the parental body divides into many daughter cells simultaneously during the unfavorable conditions to increase the chances of survival of daughter cells.In this, the reproductive unit is whole parental body.
Hope this helps :)
Answer:
Fungi compete with bacteria for resources
Explanation:
Alexander Fleming discovered the Fungi called Penicillium notatum. He discovered that his culture was contaminated by a Fungi mold and the Bacteria in the culture were dying.
He figured out the mold as the cause and found it to be Penicillium. He also discovered the death was caused by the competition of fungi and bacteria for available resources and the fungi’s interference with the cell wall(cell lysis) of the bacteria.Several years later after technological advancements and researches , the fungi was extracted and isolated and produced in large quantities as a potent antibiotic.
