I believe the correct answer from the choices listed above is the third option. The Endangered Species Act was established in 1973. This significant environmental law provides all of the following except <span>permits to trap threatened wildlife. Hope this answers the question.</span>
The right answer is A rapid temperature increase will give a melting point range that is too high.
The melting point is determined in a capillary tube. it means the temperature at which the substance is completely melted, indicated by the disappearance of the solid, will not differ by ± 4 ° C from the given value, unless otherwise indicated.
The following technique can be applied to determine the melting point:
Grind some amount of substance in a small mortar. Place in a vacuum desiccator containing silica gel or phosphorus pentoxide and allow to dry for 24 hours at room temperature (unless another method of drying is indicated in the test protocol) . Introduce the substance into a dry capillary tube 1 mm inside diameter to form a column about 3 mm high. Heat the melting device to a temperature 5 to 10 ° C below the expected melting temperature and adjust the heating so that the temperature of the enclosure rises by approximately 1 ° C per minute. Introduce the capillary tube containing the substance into the heated chamber and note the temperature at which the agglomerated substance becomes completely transparent; this temperature constitutes the melting point.
Answer:
120 white individuals
30 yellow individuals
10 green individuals
Explanation:
Available data:
- Dominant epistasis: Phenotypic frequencies 12:3:1
- W allele codes for a dominant white phenotype
- w allele codes for a colored squash
- Y allele codes for a dominant yellow phenotype
- y allele codes for a recessive green phenotype
- W allele will always mask the phenotype produced by Y or y alleles

F1 Phenotypic Frequency)
White phenotype: 12/16 = 120 individuals
Yellow phenotype: 3/16 = 30 individuals
Green Phenotype: 1/16 = 10 individuals
To know how many offspring are expected to have the white, yellow, and green phenotypes, you can perform a three simple rule. This is:
16 ------- 160 offspring
12 White ------- X = 120 offspring
3 Yellow ------- X= 30 offspring
1 Green --------X = 10 offspring
The answer to this question is estuaries or mangrove swamps, which are found in estuary environments. Estuaries are the transition between fresh water rivers and the ocean, and the salinity of estuaries change dramatically depending on the relative dominance between the fresh water and marine environments. These are euryhaline species that can tolerate a wide range of salinities, and include mangrove swamp and certain fishes.
