Veterinary scientists argue that for livestock, poisoning from plants often happens because of poor herd management.
a. True
b. False

Answers

I believe the above statement is true. To be efficient and profitable, dairy operations require good, simple management protocols to be followed. Factors contributing to plant poisoning are starvation, accidental eating and browsing habits of animals that results from poor herd management. It is therefore important to ensure proper herd management to prevent losses that may arise from death of cattle from plants poisoning.

Answer: True

Most livestock poisoning by plants often happens due to poor herd management. The poisoning is usually associated with lack of forage due to range conditions such as drought that leads to starvation, cold and other incidences that can influence an animal where it will eat too much of vegetation including those poisonous plants. Additionally, this could result to disruptive harvesting of livestock in rangeland and pastures, making it unprofitable.

Use the numbers to put the steps of translation in order, from first (1) to last (5). The large ribosomal subunit completes the initiation complex. A stop codon is reached. The initiator tRNA binds to the start codon. Amino acids are paired with anticodons, gradually forming a long chain. The small ribosomal subunit joins the mRNA strand, and the start codon is identified.

Answers

Translation is a complex process that translated the genetic information from the language of DNA in the language of RNA. The first step in this process is the binding of the initiator tRNA (that is bound to the aminoacid methionine) to the small ribosomal unit. Then, the small ribosomal unit joins the mRNA; it is the part of the ribosome mainly responsible for translating. After that, the initiator tRNA binds to the start codon. This reaction frees some initiation factors that make large ribosomal units bind to the small one. Hence, the large ribosomal subunit completes the initiation complex afterwards. The role of the large ribosomal unit is mainly to make the peptidic bonds between the aminoacids in the new protein. After that, amino acids are paired with anticodons, gradually forming a long chain; this chain is called a polypeptide and is the skeleton of the protein that is created. Finally, this process stops when one of the three possible stop codons are reached.

3, the largest ribosomal subunit completes the initiation complex

5,A stop codon is reached

2, the initiator TRNA binds to the start codon

4,Amino acids are paired with anticodons gradually forming a long chain

​the concentration of proteins synthesized in the breast is more affected by the _____.

Answers

The correct question for this is: "The concentration of proteins synthesized in the breast are more affected by _____ than _____."

The correct answers are the age of the infant and maternal intake and maternal serum proteins. 

While maternal intake and serum proteins contribute to the proteins synthesized in the breast tissue, the age of the infant will affect the composition of the breast milk as he or she ages. This is because of the reason that the demand for nutrients of the infant should be fulfilled until the recommended breastfeeding age of 2 years old.

Which organs or tissues prefer to use ketone bodies such as acetoacetate as a fuel energy source instead of glucose?

Answers

I think the appropriate would be the heart muscles and the renal cortex. Ketone bodies are three water-soluble molecules (acetoacetate, beta-hydroxybutyrate, and their spontaneous break down product, acetone) that are produced by the liver from fatty acids during low food intake (fasting), carbohydrate restrictive diets, starvation, prolonged intense exercise, alcoholism among others. In some tissues acetoacetate and beta-hydroxybutyrate can be reconverted to acetyl-CoA to produce energy. The heart gets much of its energy from ketone bodies, although it also uses a lot of fatty acids. The brain gets its energy from ketone bodies when insufficient glucose is available, e.g. during fasting.

"a nurse is explaining the nursing process to a nursing assistant. which step of the nursing process should include interpretation of data collected about the client?"

Answers

I think the step is Evaluation. In this step an actual or potential client health problem is based on the analysis and interpretation of the data previously collected during the assessment phase of the nursing process. Gathering data is included in the client's assessment. Nursing interventions are based on the earlier steps of the nursing process. The plan of care includes nursing process. The plan of care involves action to meet the needs of the clients. The nursing actions planning is done upon identifying the clients needs.

The diagnosis step of the nursing process includes the interpretation of data collected about the client. It involves critical thinking to identify health problems and forms the basis for planning care and evaluating outcomes.

The step of the nursing process which should include interpretation of data collected about the client is the diagnosis step. During the diagnosis phase, the nurse analyzes the data gathered during the assessment to identify the client's health problems, issues, and strengths. This step involves critical thinking and clinical judgment to determine whether the data suggest a typical pattern or whether there are inconsistencies that require further investigation. It is a vital part of the nursing process as it directly informs the planning of care and subsequent interventions.

Following the diagnosis, the nursing process continues with planning outcomes, implementing care, and finally, evaluation. The nurse uses the data to establish expected outcomes tailored to the client, and during the evaluation phase, the outcomes are assessed to determine if the interventions were successful, necessitating the maintenance, modification, or cessation of the nursing action.

Hybrid zones provide an opportunity to investigate _____. see concept 24.3 (page 514) view available hint(s) hybrid zones provide an opportunity to investigate _____. see concept 24.3 (page 514) mutations punctuated equilibrium the evolution of reproductive isolation allopatric speciation polyploidy

Answers

Final answer:

Hybrid zones allow us to study the evolution of reproductive isolation and speciation, as these zones facilitate significant genetic mixing and evolution of reproductive barriers.

Explanation:

Hybrid zones provide opportunities to investigate the evolution of reproductive isolation. A hybrid zone is a region where interbreeding happens between two closely related species, resulting in hybrid offspring. In these zones, extensive genetic mixing can occur, offering a rich area for studying the mechanisms that can prevent or reduce gene flow, thereby influencing the formation of new species, a concept known as speciation. Moreover, as hybrids can have features from both parental lines, studying them can provide insights into allele fitness, leading to strengthened reproductive barriers, furthering our understanding of allopatric speciation.

Final answer:

Hybrid zones enable examination of the evolution of reproductive isolation, along with reinforcement (increased divergence), fusion (merging of species) and stability (continuous production of hybrids). They provide insight into the processes of species evolution and speciation, especially concerning the nature of reproductive isolation and events like polyploidy.

Explanation:

Hybrid zones provide an opportunity to investigate the evolution of reproductive isolation. This is because a hybrid zone is an area where two closely related species continue to interact and reproduce after speciation has occurred. Depending on reproductive barriers and the relative fitness of the hybrids, reinforcement, fusion, or stability may result.

Reinforcement refers to increased divergence between species due to the low fitness of hybrids, effectively encouraging the species to evolve further apart. Fusion, on the other hand, can occur when reproductive barriers weaken, causing two species to merge back into one. Stability occurs when reproductive barriers and the fitness of hybrids remain constant, allowing for the continuous production of hybrid offspring.

Species evolution, the formation of new species (speciation), the nature of reproductive isolation, prezygotic/postzygotic barriers and events like polyploidy are all related aspects that can be studied in the context of hybrid zones.

Answers

17. C.
20.C. A  sudden warming causing the penguins to move north
21.A. Mutations

Answer 17: B). A population of salmon with different skin colors that attract mates.

The natural selection is a phenomena of differential survival and reproduction, the organisms that have better phenotypic trait are likely to survive and reproduce in the adverse environment. The population of salmon with different skin colors that attract the mates is the most likely scenario of natural selection because in the competition among members of the salmon in order to obtain their mates. The members that have a better phenotypic trait that is a color which is being more attractive for members of the opposite sex, likely to get the mate and reproduce.

20: A) An earthquake has happened to divide some arctic land and over time one penguin species became two different species that could no longer mate and reproduce.

Speciation is a natural phenomena in which a new species is formed from the existing parent species when some of the members of the population of the species get separated by geographic, behavioral and biological barriers. Such individuals because of these barriers do not inbreed resulting in the condition of reproductive isolation.

An earthquake has happened to divide some arctic land and over time one penguin species became two different species that could no longer mate and reproduce is an example of the speciation in the penguin population. The division of the land because of the earthquakes will separate the penguin population in two distinct lands. The separated land populations will evolve new traits and will be developed as new species.

21: A). Mutations

A mutation is a alteration or a change that occurs at either at a single base or the entire genome of the organism. This change brings the variation in the trait or particular characteristic of the organism. These variations can be transmitted to the population by sexual mode or reproduction and inheritance.

Many protist alternate between diploid and haploid stages during their life cycle in a process known as

(A) alternation of generations

(B) conjunction

(C) sexual reproduction

(D) asexual reproduction

Answers

The correct answer is "alternation of generations".

Alternation of generations is a reproductive cycle demonstrated by some plants, fungi, and protists. In protists, it starts with a sporophyte (diploid; 2n) that undergoes meiosis to produce spores which are haploid (n) reproductive cells. These haploid spores undergo mitosis to produce gametophytes (still haploid). These gametophytes will release haploid gametes wherein two will fuse to produce a diploid zygote. This zygote will undergo mitosis to produce a sporophyte. This is the life cycle of some protists which exemplify alternation of generations.

The fact that a strain of yeast with a certain defective gene can use the human version of the gene to repair itself is evidence that yeast and humans - A) depend on the same food supply B) share a genetic code Eliminate C) both have eukaryotic cells D) have identical genomes

Answers

Let's look at each individual answer:
A) We know this is factually wrong; humans and yeast eat different things. This question is about the micro-level of molecules, so we cannot infer much about the food of the organisms.
B) This is correct. If we did not share a genetic code, the yeast cell would not have been able to "translate" the genetic information in human genes in order to fix the problem. The genetic code is universal in life as we know it; we can transfer microbial DNA in humans and our cell machinery will still be able to utilize it and this is the basis of DNA recombination.
C) Again, this is not necessary. See the example in B (there are prokaryotic bacteria that illustrate the point).
D) This is plain silly; the genome determines to an extreme part our appearance etc. and it is obvious that we only share a small part of our genome with yeast, and certainly not all of it!

Answer: Option B

Explanation:

The yeast and human beings are genetically different but some part of their genome is same.

The yeast and the human beings are similar in the way that they share the same genetic code. This is the reason when required the yeast can use a part of the human genome to compensate for the defective part of the gene.

The yeast and the human genome contains some part as in common so that human genome can be used in case of the emergency.

Answers

The processes that lead to most genetic variation in sexually reproducing organisms are as follows;
- cross over
- independent orientation of chromosomes in meiosis
- random fertilization
The behavior of chromosomes during fertilization and meiosis is what brings most of the variation that arises each generation during sexual reproduction.

Answer:

The correct answer is crossing over.

Explanation:

Genetic variation in organisms is the basis of diversity of organisms on this planet.

This genetic variation in organisms happens during the time of gamete formation in meiosis where the exchange of chromosome takes place in pachytene stage of prophase I. This exchange of segment is called recombination which produces a unique combination of the allele.

Thus, crossing over is the correct option.
