The molecules are being aggravated, moving faster and creating heat as they become heated they move faster and move father apart from each other, causing a rise in temperature.

Answer:
polygenic; multifactorial
Explanation:
A polygenic trait can be defined as any phenotypic feature of an organism that is controlled by the action of several polymorphic genes which interact with the environment to produce a given phenotype (i.e., they are multifactorial traits). The polygenic traits are controlled by many genes localized in different regions of the genome (i.e., <em>loci</em>) and exhibit a continuous range of variation, where each genomic region associated with the variation of the trait is called Quantitative Trait Locus (QTL). Some examples of polygenic/quantitative traits include, among others, height, hair color, weight, blood pressure, etc.
Answer: Blood is slightly more viscous then water, pH is slightly alkaline it is about 8% of ones body total body weight the rest of the options are slightly wrong.
Explanation: Blood is red in colour, a dark red when it is deoxygnated and bright red when oxygenated. Its normal pH is 7,4 making it slightly alkaline and it accounts for 8% of one's total body weight with 92% being water. Its temperatures ranges around our normal body temperature which is 37°C.
