Answer:
The sporophytes of ferns grow through the rhizome
Explanation:
The gametophyte are responsible for sexual reproduction in plants while the sporophytes are usually responsible for asexual reproduction in plants.
Sporophytes are found in the rhizomes of plants and they help in the asexual reproduction.
This is how rhizomes are involved in asexual reproduction of ferns
Answer:
Explanation:
The seven largest natural satellites in the solar system (over 2,500 km in diameter) are the four Jovian Galilean moons - Ganymede, Callisto, Io, and Europa - Saturn's moon Titan, Earth's own Moon, and the satellite captured natural of Neptune Triton.
They move around a larger body. They revolve around these bodies because of their gravitational pull. The orbits that they describe when turning on these bodies can be regular or irregular.
Natural satellites of planets in the Solar System
Mercury → 0.
Venus → 0.
Earth → 1.
Mars → 2.
Jupiter → 79.
Saturn → 82.
Uranus → 27.
Neptune → 14.
Processes by which organisms produce food
Answer:
b. the bottleneck effect.
Explanation:
The bottleneck effect occurs when a population's size is reduced for at least one generation. This will result in a very reduced genetic variation, which can lead to further adaptation problems.
The Founder effect has its similarities (in terms of the resulting reduced genetic pool) with the bottleneck effect, BUT it occurs when a new colony is started by a few members of the original population.
The Hardy-Weinberg equilibrium is a principle in population genetics that states that the genetic variation in a population will remain constant from one generation to the next IF certain conditions are present (no migration, aleatory mating, among others), so this is not the answer.
Genetic drift (refers to the change in the frequency of an existing gene variant in a population due to random sampling of organisms, so it is not the answer.
Answer:
Option B
Explanation:
The presence of these structures in this stage may be a prediction of a common ancestor as these structures are not gills because they do not develop into gills in chicks and humans but being so similar to gill structures in fish at this stage in their embryo suggests that chicks and humans share a common ancestor with fish.
