An officer can use which of the following to establish probable cause?​

In cattle, there is an allele called dwarf which the heterozygous genotype produces calves with legs which are shorter than normal. This is a homozygous recessive lethal trait in which the homozygous recessive dwarf calves spontaneously abort early or a stillborn. If a dwarf bull is mated to 400 dwarf cows, how many dwarf calves would you expect? Assume all 400 cows had calves born alive and healthy.

Practically all the clinical signs of shock are associated with ________________ & ________________. [Blank1] [Blank2]

After treatment for shock, most patients are not at risk for organ failure. True or False?

What comprises the “congestive” part of Congestive Heart Failure? (2 things)

Virtual Lab Q: What is the purpose of including known TNF1 and TNF2 DNA samples in the loading sequence? A:  The purpose of including known TNF1 and TNF2 DNA samples in the loading sequence is to serve as positive controls. This helps verify that the PCR and gel electrophoresis processes are functioning correctly by ensuring that the known DNA sequences are properly amplified and detected.  

Virtual Lab Q: What is the purpose of using a running buffer instead of deionized water when running a gel? A: Running buffer provides ions that facilitate the conduction of electric current through the gel, which is essential for separating DNA or proteins during electrophoresis.  

A solution with a pH below 7 is considered __________.

Answer the following questions using the gel picture below. Which lane(s) contain molecule C?

Each person inherits two copies of any given gene from their parents. Those who inherit two copies of the same gene variants (variants are called alleles) are known as homozygous individuals (the prefix “homo-” means “the same”). Those who inherit two different alleles of the gene are known as heterozygous individuals (the prefix “hetero- “means “different”). Whether an individual is homo- or heterozygous is their “zygosity.” Determine and record the zygosity of samples 1, 2, and 3, from the simulation, in the table below.   DNA Sample 1 DNA Sample 2 DNA Sample 3 Zygosity (homo/hetero) [DNA1] [DNA2] [DNA3] Allele (s) contained (TNF1 and/or TNF2) [DNA4] [DNA5] [DNA6]
