Space Observatory Technology. Space observatory is any instrument in outer space which is used for observation of distant planets, galaxies, and other outer spaceobjects. A large number ofobservatories have been launched into orbit, and most of them have greatly enhanced our knowledge of the cosmos.
Answer:
D
Explanation:
Atomic radius is the distance from the atom's nucleus to the outer edge of the electron cloud. In general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.
Question continuation;
..........type B. Type A is found to be more common in the mainland population from which the island was settled.
How could a geneticist best explain the dominance of blood type B in the island population?
Multiple choices;
A. Random mutations have occurred in the island population.
B. Genetic drift has reduced the frequency of type A individuals.
C. Natural selection has only occurred in the mainland population.
D. Environmental conditions on the island are less favorable for type B individuals.
Answer;
B. Genetic drift has reduced the frequency of type A individuals.
Explanation;
-Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance.
-It occurs in all populations of non-infinite size, but its effects are strongest in small populations.
<em>I no see table but uh both a and b are "Space Object" so you only have C Composition rocks...???</em>
The preferred prey item would be frogs.
What is optimal foraging theory?
It is a theory in ecology that proposes that predating animals that get the most energy from minimal efforts are favored by natural selection.
In order words, selection forces prefer investing minimum energy in order to extract maximally available energy.
In this case, the heron needs to use the lowest time to harvest the maximum energy possible. Since all the preys offer the same amount of energy, the one that requires the lowest time would be preferable for the heron.
In other words, frogs would be the most preferable prey.
