Answer:
Nitrogen is essential for all living things because it is a major part of amino acids, which are the building blocks of proteins and of nucleic acids such as DNA, which transfers genetic information to subsequent generations of organisms. hopes this helps let me know :)
Water is attracted to ions, such as sodium, potassium, phosphate, and chloride ions. Maintenance of normal intracellular fluid volume depends largely on the intracellular concentration of potassium and phosphate ions. Maintenance of extracellular water volume on the other hand depends primarily on the extracellular concentration of sodium and chloride ions.
Answer:
Explanation:
Edward B. Titchener. Functionalists, including psychologists William James and James Rowland Angell, and philosophers George H, they stressed the importance of empirical, rational thought over an experimental, trial-and-error philosophy.
hope it helps
Answer:
There will be 12 chromosomes
Explanation:
We have given that The epithelial cells in the skin of an animal have 24 chromosomes
We have to find the number of chromosomes present in the gametes of this animal
We know that number of chromosomes present in the gametes is given by
So number of chromosomes in gametes 
INCOMPLETE DOMINANCE INHERITANCE:
<span>5. In Andalusian fowl, B is the gene for black plumage (head feathers) and B' (pronounced "B prime") is the gene for white plumage. These genes, however, show incomplete dominance. The heterozygous (BB') condition results in blue plumage. List the genotypic and phenotypic ratios expected from the following crosses: a) black x blue b) blue x blue c) blue x white</span>
<span>6. </span><span>In snapdragons, petal color is determined by a single gene locus with two alleles making the "red" allele (R) incompletely dominant to the "white" allele (r). Heterozygotes have petals, which are neither red nor white, but pink. a) If a true-breeding red flower is pollinated with pollen from a white flower: What fraction of the seeds (F1 generation) would be expected to produce red-flowered plants? What fraction of the gametes produced by the F1 plants would be expected to bear the R allele? b) If two pink flowered plants are crossed, what genotypic and phenotypic ratios are expected among the offspring (F1 generation)?</span>
