When a BB male and a Bb female are crossed, 50% BB and 50% Bb genotypes are produced and a 100% black phenotype.
The entire number of genes that an organism receives from its parents makes up its genotype. Alleles, which are pairs of these genes, are found. One gene is dominant and one gene is recessive in each allele.
The dominant gene is always expressed in a cross if it is present. Only when a pair of alleles is made up of two recessive genes does the recessive gene express itself. In this instance, the white fur is subordinate to the black fur. White fur is represented as b, while black fur is represented as B.
We can see that when we cross the BB male and Bb female, we will get a genotype that is 50% BB and 50% Bb, as well as a phenotype that is 100% black fur.
Parents: BB x Bb
Gametes: B, B, and B, b
Offspring: BB, BB, Bb, Bb
The genotypic ratio = 1:1
The phenotypic ratio = 1:0
Genotype probabilities:
P(BB) = 2/4 = 0.5 or 50%
P(Bb) = 2/4 = 0.5 or 50%

I’m very sure it would be carbon dioxide, plants use carbon as part of photosynthesis, glucose is there food, oxygen is their afterproduct. So the answer is carbon dioxide
D. metamorphic -> melting -> igneous -> erosion
Explanation:
The sequence that would be the best possible for a rock going through the rock cycle is metamorphic rocks melting to produce igneous rocks that are eroded.
- The rock cycle shows the pathway by which different rock types are formed.
- The origin of the formation of rocks starts with the production of magma.
- Igneous rocks are formed from cooling and solidification of molten magma.
- Metamorphic rocks are formed from the subjection of igneous and sedimentary rocks to high temperature and pressure.
- Sedimentary rocks are formed from weathering, erosion, transportation and deposition of rocks.
- Option D shows a metamorphic rock melting to give igneous rocks and the igneous rock is eventually eroded to form sedimentary rocks.
