Answer:
animals also include vitamins, which are organic compounds required in microgram or milligram amounts.[Since plants are the primary origin of nutrients for humans and animals, some micronutrients may be in low levels and deficiencies can occur when dietary intake is insufficient, as occurs in malnutrition, implying the need for initiatives to deter inadequate micronutrient supply in plant foods.
Explanation:
Answer:
Explanation:
Long-term Self-Renewal: Stem cells are capable of division while remaining unspecialized.
Differentiation
: Stem cells can divide asymmetrically, where one stem cell divides into two cells that have different cellular fates.
Induced Pluripotency
: Stem cells that have been artificially created from specialized cells are called induced pluripotent stem cells.
Considerations
: Due to their unspecialized nature, stem cells have a large research potential. The most pluripotent stem cells derive from the human embryo.
1. Amphibians has moist slimy skin meanwhile fish has scales.
2. Fish uses gills for breathing, but amphibians are different. Young ones uses gills, but adult amphibians uses lungs and even skin for breathing.
Examples of amphibians include frogs and toads.
Both fish and amphibians are one of the 5 types of vertebrates under animals. Besides fish and amphibians, other vertebrates includes mammals, reptiles and birds.
Answer:
The correct option is B) a pattern of biological functioning that occurs on a 24-hour cycle.
Explanation:
Biological rhythm is defined as the regular variation of an organic function related to the course of time, circadian biological phenomena (around the day), are those with a period of approximately 24 hours.
Circadian rhythms are physical, mental and behavioral changes that follow a daily cycle (the biological rhythm), and that respond primarily to light and darkness in an organism's environment. This cycle close to 24 hours, allows to recognize the sleep-wake phenomena and their homeostatic action, in the systemic processes of every living being. The circadian system is composed of photoreceptors, pacemakers and efferent pathways that allow a regular functioning of the sleep and wakeful state.
