Tay-Sachs destroys nerve cells in the brain & spinal cord. Pku is a birth defect that causes amino acids to build up in the body. They are similar because you can get seizures from both & in both there is also slow growth.
C. BAT can detect sound at a frequency of 67,000 Hz. Its frequency range is 2,000 - 110,000 Hz67 - 45,000 Hz.
An elephant's frequency range is 16-12,000 Hz.
A tree frog's frequency range is 50 - 4,000 Hz
A dog's frequency range is 67 - 45,000.
Bats have very sensitive hearing to cope with their nocturnal activities. Since the feed at night time, they have difficulty in seeing their prey.
Bats navigate and locate their prey using echolocation. Echolocation is a method where bats produce a very loud sound and assess the sound's echo. The echo has two types of frequency. Constant frequency, used to detect object, and Frequency modulated, used to assess the distance of the object. Bats then know the presence of its prey as well as its location.
Answer:
II. meiosis
III. fertilization
IV. gametes
Explanation:
Gamete formation and fertilization are the processes performed by all the sexually reproducing organisms. Gametes are the cells that are formed in the male and female sexual organs of these organisms. Formation of gametes occurs by meiosis and therefore, the gametes of a diploid organism are always haploid.
Male and female gametes fuse during the process of fertilization and form the zygote which in turn divide repeatedly to produce an embryo. For instance, sperms and eggs are the male and female gametes that are formed in testes and ovaries of male and female human individuals respectively. The fusion of sperm and egg produces a zygote that finally develops into a young one.
