Answer:federal
Explanation:
Natural selection is the primary process that drives Darwin's theory of evolution, the correct option is a.
Darwin's theory of evolution is primarily driven by the process of natural selection. Natural selection is the mechanism by which certain heritable traits become more or less common in a population over successive generations. It occurs due to the differential reproductive success of individuals with advantageous traits that are better suited to their environment. Individuals with beneficial traits are more likely to survive and reproduce, passing on their advantageous traits to their offspring.
Over time, this leads to the accumulation of favorable traits within a population, while less advantageous traits become less prevalent. Natural selection is driven by various factors, including environmental pressures, competition for resources, and adaptation to changing conditions. It is a key driving force behind the diversity and adaptation of species observed in the natural world, the correct option is a.

d. Mutation
B) flagella
C) cytoplasm
D) cell membrane
Answer:
Hypertonic solution
Explanation:
A solution with higher solute concentration is called as hypertonic solution while the one with less solute concentration is termed as hypotonic solution. Osmotic movement of water occurs from hypotonic to hypertonic solution to balance the concentration of solution. When an animal cell is placed in a hypertonic solution, it loses water through osmosis and shrinks.
autotrophs
heterotrophs
hermaphrodites
The correct answer is option C
All the animals are Heterotrophs as they cannot perform photosynthesis.
Except some of the sponges, all the animals are heterotrophs as they cannot make their own food(photosynthesis).
Heterotrophs depends on autotrophs or some other organisms for their food.
They are dependent on other organisms for their energy needs.
Answer:
The correct answer will be- the bark of an oak tree by Antonie Van Leeuwenhoek
Explanation:
The development of light microscopy began before the 18th century where a scientist named Antonie Van Leeuwenhoek observed the first living cells of the organisms.
Although the first cell was observed by the Robert Hooke when he observed the dead cells of the bark of a tree bu the light microscope designed by the Leeuwenhoek helped him to observe the living cells from the pond life and he also observed the bark of an oak tree.
Thus, the bark of an oak tree by Antonie Van Leeuwenhoek is considered the first cell.
