Answer: Hydrogen-3 or tritium as it is commonly called, has a half life of 12.32 years. If you start with 20 grams of it, how much will remain after 25 years? Ending Amount = Beginning Amount / 2 (time / half-life) Ending Amount = 20 / 2 (25 / 12.32) Ending Amount = 20 / 2 (2.0292) Ending Amount = 20 / 4.0818. Ending Amount = 4.8997 grams

Explanation:
Recessive alleles lack the power to express the phenotypic traits of an organism. In order for the specific trait to be expressed, 2 copies of the recessive allele or homogenous recessive genotype is needed in the organism.

Plant types matched with their descriptions
- Hydrophytes - Aquatic plants
- Mesophytes - Plants with habitats that are neither too wet nor too dry
- Xerophytes - Plants with very dry habitats
Hydrophytes are aquatic plants that may be free floating, fully submerged or partly submerged (amphibious) in water. The vascular tissue of hydrophytes is very poorly developed. Examples of hydrophytes are Ottelia, Sagittaria and Utricularia.
Mesophytes are plants that live in habitats that have a moderate supply of water (neither too wet nor too dry. Mesophytes are usually large, fast growing, and have well developed roots and leaves. Examples of mesophytes are clover and maize (corn).
Xerophytes are plants that are able to thrive with very dry habitats where the available soil water is low. Examples of xerophytes are Acacia and Carthamus.
