Answer:
Uranus
Explanation:
A new study finds that the same impact that knocked Uranus sideways may have also created the planet's moons. ... However, Uranus is an oddball in that its axis of spin is tilted by a whopping 98 degrees (relative to the plane of the solar system), meaning it essentially spins on its side.
Answer:
The correct option is ALL THE REDWOOD TREES THAT LIVES IN A FOREST.
Explanation:
In the study of the ecosystem, population refers to a group of living organisms that belong to the same species and which live in the same area and interact with one another. In the options given, option A is wrong because a spider and a fly are not the same specie. Option C is wrong because all the plants that live near each other in a forest can not be the same species. Option D is wrong because all the coyotes on earth are not living in the same environment, where they can interact with one another. Option E is wrong because the earthworm that live in a grassland and the one that live in the forest are not living in the same environment and therefore can not interact.
Answer:
C) The ancestral population probably had this type of blood pigment, but it was lost through genetic drift in the other 29 populations.
Explanation:
The presence of a blood pigment that is extraordinarily effective at carrying oxygen is a beneficial genetic trait and should be favored by natural selection. According to the given information, the organisms of only a single population of pupfish have this trait while the others do not have it.
This means that the trait was present in the ancestral populations of the pupfish but was lost in the other populations due to some accidental/chance event. Loss or fixing of an allele by a chance event is called genetic drift. It does not include any natural selection but results in a random change in the allele frequencies of a population. Therefore, loss of the trait by genetic trait might have occurred in the other populations.
The correct answer is A. Between the visceral and parietal layers of serous membranes
Explanation:
Serous fluid is a type of pale yellow fluid similar to mucus that is secreted by certain membranes to reduce friction in body cavities. This can be found on different organs in the body including the digestive system, for example in the peritoneum that encloses multiple organs in the abdomen. Additionally, serious fluid develops between two main layers: the visceral layer that covers the organs and the parietal layer that follows the visceral layer. According to this, serous fluid reduces friction "between the visceral and parietal layers of serous membranes".
