Out of the choices given, enemy nations using sophisticated warfare to overpower the outdated tactics of the empire brought an end to the great West African empire. The correct answer is C.
Answer:
A hypothesis is a tentative statement about the relationship between two or more variables. It is a specific, testable prediction about what you expect to happen in a study.
They might have a common ancestor.
For the transport of metals across the fluids and the body membranes, the intracellular potential is needed. But sometimes due to the toxicity of lead, the process is affected especially in the digestive tract.
How bioaccessibility of lead is affected in the human digestive tract?
Both the organic (tetra alkyl lead) and inorganic forms of lead have been demonstrated to be extremely hazardous in experimental studies. This lead absorption, which typically occurs by inhalation or food contamination, is influenced by variables including absorption rate, particle size, and solubility. The majority of the lead that is inhaled is in tissues that contain minerals. Following speciation, Lead's binding power increases in comparison to Zinc and Calcium, which has an impact on fluidity. Lead's bioavailability seems to be reduced when food is present. The concentration of lead may also be reduced by pyromorphite. Since solid state speciation happens when the pH is between 6 and 7, Now, this results in a change in circumstances from the stomach to the intestinal tract, leading lead to transform into lead phosphate, which is less soluble and reduces bioaccessibility.

Answer:
1.) Inflated pod shapes (Cc) in the F1 generation
2) See attached image for the work out of the cross from P generation to F2 generation.
3). CC- 1/4, Cc- 1/2, cc- 1/4
Explanation:
This question is related to the pod shape trait encoded by a single gene in pea plants. The alleles for inflated pod shape (C) is dominant over the allele for constricted pod shape (c). This means that allele "C" will be expressed over allele "c" in a heterozygous state.
The two truebreeding parent plants will have genotypes: CC (inflated pod shape) and cc (constricted pod shape). When these two plants are crossed, an all heterozygous plant with genotype: Cc will be formed in the F1 generation. Since, C is dominant over c, the F1 Cc plants will have an inflated pod shape phenotype.
The F1 Cc plants are self-crossed to produce the F2 generation offsprings i.e. Cc × Cc. The gametes C and c will be produced by each F1 parent, which will be used to draw a punnet square (see attached image). From the cross, offsprings with genotypes: CC, Cc and cc are produced in the F2 generation.
CC (phenotypically inflated pod shape)- 1/4
Cc (phenotypically inflated pod shape)- 1/2 or 2/4
cc (phenotypically constricted pod shape)- 1/4
