Answer:
The question lacks options, the options are:
A) 1 out of 16
B) 3 out of 16
C) 6 out of 16
D) 9 out of 16
The answer is 1 out of 16
Explanation:
This is a DIHYBRID cross because it involves two different genes coding for distinct traits. One of the traits will be dominant while the other recessive. Hence, parents that are purebred for opposite forms of the trait means that one parent is homozygous dominant while the other is homozygous recessive. When these two parents cross, they produce F1 offsprings that all possess the dominant trait but heterozygous/hybrids.
When these hybrids are self-crossed, they produce four different combinations of gametes which when crossed using a punnet square will result in F2 offsprings with a 9:3:3:1 phenotypic ratio according to Mendel's observation.
9 represents offsprings that are dominant for both traits
The two 3's represents offsprings that are recessive for one trait and dominant for the other respectively.
1 represents offsprings that are homozygous recessive for both traits.
Hence, 1 out of 16 offsprings will be homozygous recessive for both traits.
Answer:
<em>The correct option is C) Continental shelves</em>
Explanation:
The continental shelf can be described as a part of a continent which is submerged in shallow water. This shallow water is known as a shelf. Hence, the name continental shelves.
Rich deposits of oil and natural gas can be present in this part of the sea. The continental shelves are of extreme commercial significance and are a commercial site for exploitation. The continental shelves can be rich in metallic and non- metallic ores and hydrocarbon products.
Answer: There are two ways to determine the age of a dinosaur fossil. One is called relative geologic time, which involves deciding whether one dinosaur fossil is older or younger than another. Geologists then measure the proportion of parent and daughter atoms present in the ash crystals to determine the crystal's age.

Entropy increases going from one trophic level to another.</h3><h3>Explanation:</h3>
Entropy progress going from one trophic level to another. Entropy is a division for the disorderliness of a system. As the trophic level move to the other, energy is lost so more chaos occurs which inflates the entropy.
