When organisms mate without human interference, it is called natural selection.
The red-legged frog breeds in ephemeral ponds from January through March. Its relative, the bullfrog, breeds in permanent ponds from late March through May. There are two pre-mating isolation mechanism at play here,
1. Ecological isolation: The habitats are different, hence the individuals of both the species do not meet. Ephemeral ponds are temporary ponds that develop during rainy days, while the permanent ponds are full of water throughout the year.
2. Temporal isolation: The time of mating is different for both the species to avoid contact between the individuals of closely related species. Red-legged frogs mate in January to March slot and the bullfrog in the March to May slot.
It was the theory that an organism could form from something such as mud for an example.
Answer:
Option C
Explanation:
Complete question
Which term describes the perception of the body's movement through space?
A. nociception
B. neurasthenia
C. kinesthesia
D. dimensionality
Solution
The word Kinesthesia is made up of two words kinetic and anesthesia. On one side kinetic means movement while anesthesia means feeling, sensation, visions etc.
Whenever a person senses his/her body movement through space or any other kind of physical bodily movement or action, he/she actually faces Kinesthesia. This is also related with the Charles bell concept of sixth sense through which one could perceive sensation of static position or velocity of the movement
Hence, option C is correct
