1 Amplitude
2 Internal fertilization
3 Embryo
4 Electrode
Answers
Answer:
1.- the extent or range of a quality, property, process, or phenomenon.
2.Internal fertilization is the union of an egg cell with a sperm during sexual reproduction inside the female body.
3.an unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization .
4.An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit.
Answer:
Dear Mate !
Explanation:
Amplitude :
PYSICS
1.the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
"the amplitude of alpha rhythms"
2.
ASTRONOMY
the angular distance of a celestial object from the true east or west point of the horizon at rising or setting.
Internal frtilization :
Internal fertilization is the union of an egg cell with a sperm during sexual reproduction inside the female body. For this to happen there needs to be a method for the male to introduce the sperm into the female's reproductive tract. In mammals, reptiles, some birds, some fish and certain other groups of animals, this is done by copulation, the penis or other intromittent organ being introduced into the vagina or cloaca. In most birds, the cloacal kiss is used, the two animals pressing their cloacas together while transferring sperm. Salamanders, spiders, some insects and some molluscs undertake internal fertilization by transferring a spermatophore, a bundle of sperm, from the male to the female. Following fertilization, the embryos are laid as eggs in oviparous organisms, or in viviparous organisms, continue to develop inside the reproductive tract of the mother to be born later as live young.
Embryo :
1.an unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization (after which it is usually termed a fetus).
2.a thing at a rudimentary stage that shows potential for development.
Electrode:
a conductor through which electricity enters or leaves an object, substance, or region.
