sci quiz

• One of the unique characteristics of organisms is the ability to increase and produce their own kind. this process is called reproduction
• Most animals go to the union of sperm cell and egg cell to form a fertilized egg or zygote. This is called fertilization.
• Is some plants, pollen grains are transferred from other plants by insects or other animals. This is known as pollination.
• Heredity traits are controlled by genes.
• Genes are transmitted from one generation to the next.
• morphological refers to the structure such as shape, length, color of the body parts.
• physiological refers to the function of parts such as rolling of the tongue, blood clotting, or color vision.
• behavioral are externally directed activities in response to stimuli.
• sexual are associated with being male or female such as external or internal genitalia.
• hereditary characters are acquired in parents and are passed to offspring through reproduction
• asexual reproduction is the offspring is neither the product of chance combination nor genes derived from two different parent gametes.
• budding is a form of asexual reproduction in which a new organism develops from an outgrowth of bud on another due to cell division at one particular site.
• hydra is a small genus freshwater coelenterates. it is small, solitary, and only exist in the polyp form, which is radially symmetrical cylinder.
• bread mold, mosses, and ferns are produced by spore formation.
• binary fission is the primary method of reproduction in prokaryotic organisms.
• 3 classified binary fission

  simple binary fission, transverse binary fission, and longitudinal binary fission.
• longitudinal binary fission in euglena is also called symmetrogenis binary fission.
• During mitotic division, nucleus is divided in the process of karyokinesis.
• cytokinesis follows and form longitudinal furrow.
• transverse binary fission in paramecium happens under favorable condition. paramecium stops feeding and its oral groove and buccal structures begin to disappear
• simple binary fission occurs when the cytoplasmic division passes through any plane.
• in fragmentation, the parents body breaks up into several pieces.
• the growth of lost body parts of an animal is called regeneration
• propagating plants from leaves, stems and roots is known as vegetative reproduction.
• kalanchoe plants or kataka-taka have a unique way of propagating themselves.
• stem cutting is the widespread use of vegetative propagation.
• layering is another way of plant propagation. the slender bermuda grass called stolon shoots up snd bends away from the parents.
• marcotting may be employed in plants that have difficulty forming new roots.
• grafting is a method that involves a scion and the stock.
• asexual reproduction is employed to exploit suitable conditions for survival
• The variations found in offspring of sexual reproduction allow some individuals to be better suited for survival and provide a mechanism for selective adaptation to occur.
• Fertilization has been defined as the union of sperm and egg cells.
• zygote is the fertilized egg cell that grows into a baby animal
• zygote then multiplies, and grows into an embryo
• The time between the formation of the zygote and the baby's birth is called pregnancy
• The fertilized egg now starts to divide and produce the embryo. It is called an embryo from 3-8 weeks (the embryonic period.) Then after 8 weeks, it is called fetus. If continues to grow normally; it can eventually become a baby.
• zhong zhong and hua hua are the first cloned monkeys
• Asexual reproduction the production of new living organisms wherein the offspring is not a product of chance combination genes derived from two different parent gametes.
• Sexual Reproduction - the production of new living organisms by combining genetic information from two individuals of different types (sexes)
