Answer:
Doctors utilize IV saline for refilling lost fluids, flushing wounds, providing medication, and maintaining patients through surgery, dialysis, and chemical treatment. As a fashionable therapy, Saline IVs even found a space outside the hospital.
"There are significant quantities of sodium and chloride, higher than blood levels.
Explanation:
The solution of sodium chloride-water, generally known as saline, is the saline solution. It is the intravenous fluid most usually used. It was utilized since the early decades of the 19th century and is used annually in the United States alone with more than 200 million liters.
Though about 60 percent of the body consists of water, it is not possible to inject water into the blood alone, because the blood could lead to the depletion of important electrolytes.
Direct water injection into the bloodstream would likewise lead to the blood cells' osmotic impact.
Blood cells, which are predominantly salty, will take water and cause it to expand quickly until the cell membrane breaks down. The content of the cells would then leak into the plasma. A substantial proportion of body cells can be damaged to death. Death can result.
There would be no permanent harm to a little amount of water injected into the blood directly. The bigger the number of cells injured, in essence, the more water injects into the circulation.
Water is blended in a solution in sodium and chlorine at approximately the same concentration as blood plasma to avoid damages caused by pure distilled water on blood cells. The outcome is that the solution splits the circulating volume with the cellular fluid and becomes an integral part of the circulating volume without a detrimental influence on blood cells.

Which two of these characteristics does an organism with bilateral symmetry possess?
Answer:
symmetrical in many ways across a central axis" and "presence of a head".
Explanation:
Bilateral symmetry is a characteristic that many organisms has at which if we divide the body using an imaginary line, we will see two mirror images. Two characteristics that an organism with bilateral symmetry possess are symmetrical in many ways across a central axis (known as well as the sagittal plane), and presence of a head that is at the middle of the central axis. The great majority of organisms posses bilateral symmetry, including the humans.

A reproductive cell must differ from other normal body cells. The reproductive cell must ______________ because it will soon fuse with another reproductive cell to form a new individual
I'm not 100% sure what the exact answer is to this, because lots of things could be said about what gametes need to do for reproduction.
I suppose since it says that it's combining with another cell, it's hinting at the fact that reproductive cells are haploid.
If this is multiple choice I would choose the choice that has to do with gametes being haploid.
A reproductive cell must differ from other normal body. The reproductive cell must Haploid because it will soon fuse with another reproductive cell to form a new individual.
How is a reproductive cell specialized?The requires the union of two specialized cells, called gametes, each of which contains one set of chromosomes.
Thus, haploid is the answer.

Post Lab Report Part II 6. The probability that the two offspring you produced share every genotype in common is extremely low. Explain why they are likely to be different. 7. How would genetic variability be affected if more chromosome pairs were added? What about if another partner was added?
Answer:
Explanation:
Answer to 6:
The probability of two offspring with the same genotype is very low because due to recombination between the chromosomes of the father and mother each gamete has a different composition of genetic material. The only chance that they share the genotype is if they were zygotical twins.
Answer to question 7:
When you increase the number of chromosomes the variability will increase too.

Explanation:
As illustrated in this question, Gregor Mendel used the color trait of pea plant to discover his law of dominance.
The results Mendel obtained during his experiments. It showed that if you cross two plants that were true breeding for different colors (purple and white), the offspring or first generation (F1) would be HETEROZYGOUS (Pp) instead of true-breeds, and all were PURPLE in color.
Interestingly, when he crossed two of these F1 plants (Pp × Pp), their offspring did not all come out PURPLE, instead he obtain a ratio of 3 purple-flowered plant for every 1 white-flowered plant. He concluded that the “heritable factor” for the RECESSIVE trait (white flowers) was not destroyed in the F1 generation. Instead it had been MASKED by the “heritable factor” of the DOMINANT trait (purple flowers).

You isolate a variant of the Hfr parent in question 6 that only shows recombination of the his+ and trp+ genes. The cross was ( HFR lac+, gal+, trp+, his+, strr X F- lac-, gal-, trp-, his-, strs ). This strain most likely:_________.
a. Contains an F' his+ trp
b. Has become F-
c. Contains an Hfr translocation
d. No longer mates as a merry diploid
e. Not enough information is given
Answer:
The correct answer is - b. has become F-.
Explanation:
In the case of the cross of two different strains, some genetic material moves to the F- strain from the Hfr strain, but due to genome size, it's not possible that all the genes can pass into a single bacterium.
Instead of complete transfer, each individual F- cell gets a different and random subset of genes from the Hfr. There is no translocation and F' does not contain his+ trp+.

Directional selectionAnalogous structuresCharacter displacementHybridization Vestigial structuresAnswer:
Character displacementExplanation:
Competition is an ecological and evolutive process very common in nature. Competition might be intra- or interspecific. Competition between different species in a community or ecosystem might be due to the same resource use, or the same territory, shelter, etcetera. When a resource is useful for two or more species, and limited, they compete to gain it.
The principle of competitive exclusion states that different species with the same requirements sharing the niche can not coexist indefinitely based on the same limited resource. When two competing species coexist, this is because of niche partitioning or niche differentiation.
Differentiation of effective niche is closely related to character displacement.
Character displacement is the result of interspecific competition, in which two or more species that live in the same habitat manage to avoid competition by developing different traits. Morphological divergence, or any adaptative trait development, fixated genetically, is the product of niche segregation. Species tend to differentiate morphologically in the presence of strong competitors. Traits divergence favors coexistence in the same place.
In the exposed example, both species live in the same pond. But to avoid competition and competitive exclusion, species developed different teeth sizes to feed on different prey items.
Cystic fibrosis is most common in individuals of Northern European descent, affecting 1 in 3200 newborns. Assuming that these alleles are at Hardy-Weinberg equilibrium, what is the frequency of the disease-causing CFTR alleles in this population
Answer:
0.0177
Explanation:
Cystic fibrosis is an autosomal recessive disease, thereby an individual must have both copies of the CFTR mutant alleles to have this disease. The Hardy-Weinberg equilibrium states that p² + 2pq + q² = 1, where p² represents the frequency of the homo-zygous dominant genotype (normal phenotype), q² represents the frequency of the homo-zygous recessive genotype (cystic fibrosis phenotype), and 2pq represents the frequency of the heterozygous genotype (individuals that carry one copy of the CFTR mutant allele). Moreover, under Hardy-Weinberg equilibrium, the sum of the dominant 'p' allele frequency and the recessive 'q' allele frequency is equal to 1. In this case, we can observe that the frequency of the homo-zygous recessive condition for cystic fibrosis (q²) is 1/3200. In consequence, the frequency of the recessive allele for cystic fibrosis can be calculated as follows:
1/3200 = q² (have two CFTR mutant alleles) >>
q = √ (1/3200) = 1/56.57 >>
- Frequency of the CFTR allele q = 1/56.57 = 0.0177
- Frequency of the dominant 'normal' allele p = 1 - q = 1 - 0.0177 = 0.9823
Further studies of the genes in the region around the MHC locus identified C4 as a likely causative gene. A particular allele of C4 was significantly associated with schizophrenia. In addition, it was found that individuals with high expression of this allele of C4 had elevated risk of developing schizophrenia. Which of the following variants would be most likely to increase risk of schizophrenia from this allele?
a. a variant that decreases binding of an activating transcription factor to the C4 promoter
b. a 5’ UTR variant that destabilizes the C4 mRNA
c. a duplication of the C4 gene
d. a nonsense coding variant
Answer:
c. a duplication of the C4 gene
Explanation:
Schizophrenia is a disease that affects the brain, which is characterized by an imbalance of neurotransmitters and the presence of damaged brain tissues. In humans, the Complement component 4 (C4) protein is found at the neurons (i.e., cell bodies, dendrites and axons), which are the most common brain cells, and neuronal synapses. Moreover, gene duplication can increase gene expression when repressive mechanisms (e.g., DNA methylation at promoter sites) capable of silencing the expression of the duplicated gene are lacking. Recently, it has been discovered that a chromosome rearrangement associated with a tandem duplication of a genomic region that contains a C4 gene may contribute to schizophrenia risk by increasing the expression of this gene. In this example, a, b and d options are associated with a decrease in expression of the C4 gene, either by decreasing its transcription (options a and d) or by posttranscriptional mechanisms (option c).

(genotype: Cch) and the other is albino. What are the possible phenotypes
of their offspring? Construct a Punnett square to support your answer.
Answer:
- Parental cross = Cch x chch
- F1 = 1/2 Cch (agouti coat); 1/2 chch (albino coat) >> 1:1 phenotypic ratio
Punnett square:
ch ch
C Cch Cch
ch chch chch
Explanation:
A heterozygous individual is an individual who has two different gene variants (i.e., alleles) at a particular locus. In this case, individuals having the "agouti coat" trait are heterozygous carrying both 'C' and 'ch' alleles. On the other hand, a homo-zygous individual has the same allele at a given locus (here, the 'chch' genotype associated with the albino phenotype). Therefore, as observed in the Punnett Square above, when a heterozygous parent is crossed with a homo-zygous recessive parent for a single gene, alleles segregate in the gametes of both parents so an expected 1:1 phenotypic ratio will be observed.
There are six major groups of enzymes. The categories are based on the types of reactions that they catalyze. What type of enzyme can join together two molecules to make a larger molecule such as a long strand of DNA
Answer:
DNA ligase.
Explanation:
DNA ligase is a type of enzyme that is responsible for join together of two molecules to make a larger molecule such as a long strand of DNA. This enzyme joins the end of two DNA molecules making it a long strand of DNA. In DNA cloning process, restriction enzymes and DNA ligase enzymes are used to incorporate genes and other pieces of DNA into plasmids so we can say that DNA ligase is responsible for long strand of DNA.
