When a male pig from a line of true-breeding (homozygous) black, solid-hooved pigs was crossed to a female from
natita [175]

Answer:

When a male pig from a line of true-breeding (homozygous) black, solid-hooved pigs was crossed to a female from a breed (homozygous) of red, cloven-hooved pigs, their several progeny all looked alike with regard to color and hooves. These progeny were all mated to members of the same breed as their red, cloven-hooved mother pig. The offspring from this final cross were: 11 black, cloven-hooved; 8 black, solid-hooved; 14 red, cloven-hooved; and 10 red, solid-hooved. For each of these two genes (coat color and hoof type) determine which allele is the dominant one. Explain your reasoning. What were the phenotypes of the progeny produced by the first mating in this problem.

Predict the most likely outcome of culturing transformed E. coli in the presence of tetracycline.Justify your prediction.
My name is Ann [436]

Answer:

E.coli is a bacterium which is preffered for transformation due to its rapid growth and high efficiency of introduction of DNA molecules into cells.

Tetracycline is an antibiotic used to treat several infections such as cholera, plague, brucellosis, and malaria etcetra.

Plasmid is a small, extrachromosomal DNA molecule present in cell which is seprated from chromosomal DNA and have ability to replicate independently.

When a plasmid resistant to tetracycline and kanamycine is inserted into E.coli, the process is called transformation. E.coli might not be able to survive due to absence of plasmid but the transformed strains having antibiotic tetracycline and kanamycine will probably be able to survive it.

Hence, the culture of bacteria carrying plasmid will be able to survive only.

A therapist examining the roles, rules, expectations, power hierarchy, and boundaries within a
olga2289 [7]

Answer:

This question lacks options, options are:

A) family affect  

B) family strengths  

C) family process  

D) family organization.  

The correct answer is D.

Explanation:

The family is a system that is constituted by a network of relationships and made up of subsystems where each member evolves and develops through different stages, undergoing adaptation changes where the norms, rules, limits and hierarchies that work are essential in the family environment. Family therapy is understood to be that modality of therapy focused on the family as an object of intervention, its objective is to achieve the change of negative interaction patterns between the members of a family. Family organization refers to the interaction between all its members who are part of the same institution united by emotional ties. The organization describes the totality of the existing relationships between the people that make up the system, then the family organization refers to the functional demands, distribution of rules and transactional guidelines that constitute the ways of interacting of each individual within the family. The transactional guidelines are those that normalize the behavior of each member and are preserved by two systems of coercion; the first established by universal norms in turn existing roles and hierarchies; the second is the characteristic of each member involving its interests and expectations.
