Answer:
More than two complete sets of the chromosomes (polyploidy).
Explanation:
Assembly of spindle microtubules assist the chromosomes to arrange in the equator of the cell during metaphase. This is followed by the splitting of centromere and segregation of sister chromatids towards the opposite poles of the cell to ensure equal distribution of chromosomes among the daughter cells.
Any drug that prevents the assembly of the spindle apparatus would not allow the alignment of the chromosomes in the cell's equator. This would prevent the anaphasic segregation of daughter chromosomes to the opposite poles.
Some of the resulting daughter cells are most likely to have more than two sets of chromosomes.
Answer:
True
Explanation:
Tropical rain forest are one of the important biomes of the world that is characterized by a short or no dry season and a precipitation of overall 60 mm each month. They are also known as lowland equatorial evergreen rainforest. If we talk about location, they mostly are found between fall between the Tropic of Cancer and the Capricorn since they lie near to equator and they receive sufficient amount of sunshine and rain.
Due to their location near the equators, they receive greater amount of sunshine than other biomes and when sunshine is greater the rate of water evaporation is also greater that results in more rainfall.

Answer: DF508 mutation. A Genetic, Hereditary, Autosomal and Recessive Mutation.
Explanation:
Cystic fibrosis (CF) is a recessive autosomal lethal disease, it is most common on Caucasoid populations. Its diagnosis is suggested by the clinical features of chronic obstructive pulmonary disease, persistent pulmonary colonization (particularly with mucoid Pseudomonas strains), meconium ileus, pancreatic insufficiency with or familiarity history of the disease. The FC gene is large, with about 250 Kb of genomic DNA, 27 exons representing about 5% of genomic DNA; encodes a 6.5 kb transcribed mRNA. This mRNA is transcribed into a protein of 1480 amino acid called CFTR (Regulator Transmembrane Conductance Cystic Fibrosis). When a three-base pair deletion, adenosine-thymine-thymine (ATT) identified in the CFTR gene, exon 10, it results in the loss of a single amino acid phenylalanine at position 508 of the protein. This mutation is called DF508; “D” stands for deletion and “F” for phenylalanine amino acid.

Answer:
C. The rate at which soil bacteria perform nitrogen fixation
Explanation:
Since Xavier is raising vegetables in the same spot year after year it is reasonable to expect that the plants would deplete the soil of its resources. Since the soil doesn't have enough minerals and not enough time for the bacteria to perform nitrogen fixation the plants don't grow at the same rate and numbers that they used to at the beginning.
