Answer:

The eruption of the volcano made the dark red walking beans more visible. Consequently, the quantity of dark red beans consumed increased during days four, five, and six. If the pollution persisted, the population of dark red walking beans would dwindle over time.

A haploid species has a gene on chromosome 2 which codes for lactase. In nature, four different alleles of the lactase gene have
s2008m [569]

Answer:

Haploid organisms contain a single allele per locus.

Explanation:

Haploid species will always have only one allele present for any given locus. These organisms possess one full set of chromosomes in their somatic cells. Although most species are typically diploid, there are exceptions (for instance, male bees, ants, and wasps develop from an unfertilized egg). Hence, in haploid organisms, the frequencies of alleles and genotypes are identical. It is also noteworthy that the remaining three alleles will be allocated among the other haploid individuals in the population.

In an animal cell, which two cell structures do newly-synthesised enzymes have to pass through to reach the external environment
enyata [672]

Answer:

Ribosomes, Cell membrane

Explanation:

Ribosomes serve as the sites where proteins are synthesized. Therefore, they are referred to as the protein production factories of a cell. Since enzymes are a type of protein, their synthesis occurs within ribosomes.

The cell membrane functions as the boundary that surrounds the cell or separates it from its environment.

To exit the cell and enter the external environment, an enzyme must navigate through both the ribosomes and the cell membrane.

Conclusions
s2008m [569]

Answer:

This is due to a lack of proteolytic enzymes.

Explanation:

The diagnostics from the study indicate that protein digestion in the small intestine occurs at a slow rate, primarily because of either the absence or a significant reduction in proteolytic enzymes. These enzymes are crucial for enhancing the digestion speed, resulting in the production of amino acids that are subsequently absorbed into the bloodstream for muscle formation.
