Answer:
a. Stretching of the ureters during delivery
Explanation:
Postpartum urinary retention is defined as the stretching if the uterus or the genitourinary tissue which occurs in most of the women during vaginal deliveries. The postpartum bladder is vulnerable to the urinary retention. This occurs due to the physiological changes in the pregnancy period. During delivery through vagina, the genitourinary tissues becomes edematous and also gets traumatized form the labor process and thus stretches the ureters during the delivery time. But it returns to normal after 4 to 6 days of diagnosis.
Hence the correct option is (a).

Which trait is totally determined by genes
Answer:
hair color is determined by genetics
Explanation:
Which of the following is true of crossing over? It involves the exchange of chromosome segments between homologous chromosomes. It occurs in meiosis I. It increases genetic variability. All of the choices are correct.
Answer: All of the choices are correct.
Explanation:
Meiosis is a type of cell division of the nucleus that occurs in cells that will give rise to gametes (egg or sperm). These are haploid cells (n), that is, they possess only one chromosome of each of the pairs (23 in total). Through meiosis from a diploid cell (2n), four haploid cells are obtained, thanks to two successive divisions called meiosis I and meiosis II. Both comprise prophase, metaphase, anaphase and telophase.
Homologous chromosomes are a pair composed of a paternal and a maternal chromosome. They have the same DNA sequence arrangement from one end to the other, but different alleles. These chromosome copies have the same genes at the same loci where they contribute tips along each chromosome that facilitate a pair of chromosomes to align correctly with each other before they separate during meiosis. Sister chromatids are those that make up a chromosome after duplication of the genetic material.
The homologous chromosomes of maternal and paternal origin, mate and this process is called "synapsis" and form what is known as a tetrad or bivalent chromosome, giving the impression that it is a chromosome with four chromatids. In these tetrads, junctions called chiasmata are formed, areas in which both homologues exchange genetic material or genes, a process known as crossing-over. The chiasmata allow the chromosomes to be held together until their separation in anaphase l. So, genetic recombination is the process by which a segment of genetic material from a maternal chromosome is cut and then joined to a paternal chromosome (or vice versa) during prophase I of meiosis. So it happens between non-sister chromatids of a paternal and a maternal chromosome.
After crossing over, the homologous chromosomes are arranged randomly at the cell's the equator of the cell at random (methaphase), facing each other, still united in the areas where crossing over occurred. Each chromosome is associated with a meiotic spindle fiber of the meiotic spindle and they are pulled along the meiotic spindle and driven toward the respective poles (anaphase). The chromosomes are now arranged at the poles and the reorganization of the nuclear envelope and the nucleolus begins. Finally, cytokinesis occurs and the rearrangement of cellular components and reorganization of the cytoskeleton. As a result of meiosis I, 2 haploid cells are obtained and then meiosis II occurs, where the sister chromatids are separated, generating two more cells (a total of 4).
Genetic variability is generated because the gametes produced during meiosis will not inherit the same chromosomes as the mother cell, but due to crossing over, the inherited chromosomes will be genetically different.
Which structures allow lycophytes to grow bigger than mosses and liverworts?
A. gametophytes and sporophytes
b. xylem and phloem
C. haploid and diploid
D. roots and stems
The structure that allows lycophytes to grow bigger than mosses and liverworts is xylem and phloem which is option B
Lycophytes are spore bearing vascular plants. Being a vascular plant, they possess vessels ( vascular tissues) which include:
ylem: this is used for conducting water usually from the root to the rest of the plant partsPhloem: this is the vascular tissue that is used to conduct food( sugar) produced in the leaves of plants to other parts of the plant.The possession of the vessels makes the lycophytes appear bigger.
Mosses and liverworts belongs to the plant phylum Bryophyta. They do not have any vascular tissues that can be used to conduct water and food. This restricts their size.
Therefore, the structure that allows lycophytes to grow bigger than mosses and liverworts is xylem and phloem

They have developed from the same organism.
They have completed their evolutionary process.
Humans have evolved from several ancestors.
Horses have evolved from cows and humans.
Answer:
option A they have developed from the same organism
Explanation:
Organs of animals (belonging to different species) which have similar structure but different functions are homologous organs. Such organs have evolved from the same ancestors , however their function are different.
For example – wings of bats, limb of human etc.
Here in this case also the bone structures of human, cow, and horse are same but their functions are different, thus they are homologous organs and hence they have evolved from same ancestors.
The correct answer is option A

a. are energy-consuming (under standard state conditions).
b. are energy-yielding (under standard state conditions).
c. consume ATP.
d. yield ATP.
e. are strongly influenced by changes in concentration of substrate and product because of their molecularity.
f. are at or near equilibrium in the erythrocyte
Answer:
b. are energy-yielding (under standard state conditions).
d. yield ATP.
Explanation:
The reactions of glycolysis produces the ATP molecules from the breakdown of glucose molecule. Glycolysis produces 2 molecules of ATP, 2 molecules of NADH, and 2 molecules of pyruvate: Glycolysis breakdown glucose with the help of oxygen produces energy in the form of ATP, NADH, and pyruvate so e can conclude that glycolysis are energy-yielding process for the cell.

In large populations, small fluctuations in survivorship or reproduction among individual organisms are unlikely to affect allele or genotype frequencies in the population.
a. True
b. False
Answer: True.
Explanation:
A population is defined as the set of individuals that inhabit a given geographic area. A population has a certain allele frequency, which is the measure of the relative proportion of alleles in a given population, expressed as a percentage or unit. It is estimate using the number of times the allele is found in a locus and dividing it by the total number of alleles. While the genotypic frequency refers to the number of times that each of the genotypes generated by the two-by-two combinations of the alleles involved in the locus under study appears in relation to the total number of genotypes (which will be equal to the total number of individuals included in the study).
The population can be increased or decreased according to the birth and death rates. Generally, unless specific alterations occur, such as the spread of a disease, immigration, emigration, natural disasters, and others, the size of the population will remain constant. This means that the birth rate is quite similar to the death rate. And the larger the population, the more difficult it is to disturb this balance between births and deaths. So if small fluctuations in survival or reproduction occur between individuals, it is unlikely that this will affect the frequency of alleles and/or genotypes. This is explained using the Hardy-Weinberg principle states that the genetic composition of a population remains in equilibrium as long as no mutation occurs, and nor natural selection nor any other factor acts. After a generation of random mating, the frequencies of the genotypes of a locus are fixed at an equilibrium value. Then, the genetic variation in a population will remain constant from one generation to the next in the absence of extreme disturbing factors such as those mentioned above (diseases, natural disasters, and others).
Note that for this principle to be fulfilled, the population must be diploid (have two alleles of each gene), must reproduce sexually in a random manner, and must be large enough to minimize the effect of genetic drift (random fluctuations in allele frequencies from one generation to the next, due to random events that can cause certain traits to become dominant or disappear from a population).

Thymine in DNA occurs as the result of thymidylate synthase creating _______________ , which then undergoes ____________ to ____________, then to __________, and incorporated into DNA by ___________.
Answer:
The question is incomplete, the complete question is as follow:
Thymine in DNA occurs as the result of thymidylate synthase creating _______, which then undergoes _______ to _______, then to _______, and incorporated into D N A by _______. Thymine in tRNA arises ________, by an S-adenosylmethionine-dependent _______ of a ______ residue in RNA.
Answer:
Thymine in DNA occurs as the result of thymidylate synthase creating dTMP, which then undergoes phosphorylation to dTDP, then to dTTP, and incorporated into DNA by DNA polymerase. Thymine in tRNA arises posttranslationally, by an S-adenosylmethionine-dependent methylation of a UMP residue in RNA.
Explanation:
Thymidylate synthase is a key enzyme that catalyzes the synthesis of 2′-deoxythymidine-5′-monophosphate (dTMP) from 2′-deoxyuridine-5′-monophosphate (dUMP). This enzyme catalyzes the addition of a phosphate group (phosphorylation) of dTMP in order to form thymidine 5'-diphosphate (dTDP). Once synthesized, dTMP can be metabolized to deoxythymidine triphosphate (dTTP), which is a precursor for DNA biosynthesis. On the other hand, transfer ribonucleic acid (tRNA) is methylated after the molecule is synthesized. The transfer of the methyl group is catalyzed by an S-adenosylmethionine–dependent methyltransferase that catalyzes the methylation of uridine monophosphate (UMP) using SAM (S-adenosylmethionine) as the methyl donor.

Whose argument is stronger regarding the SAC curves and the LAC curve? A. The draftsman since the lowest point on each SAC curve will have a horizontal tangent line which only occurs at the lowest point on the LAC. B. Jacob Viner since the SAC curves can be adjusted slightly and still keep their U-shape in a way that makes their lowest points end up on the LAC curve. C. Jacob Viner since the long-run average cost curve must be composed of the lowest points on any individual short-run average cost curve. D. The draftsman since, while it is true that the points of tangency of the SAC curves with the LAC curve are at each SAC curve's minimum, it is impossible to illustrate it accurately.
NB: This is a business question, not biology.
Answer:
SAC (Short-run Average Cost) and LAC (Long-run Average Cost)
The stronger argument regarding the SAC (Short-run Average Cost) curves and the LAC (Long-run Average Cost) curves is:
A. The draftsman since the lowest point on each SAC curve will have a horizontal tangent line which only occurs at the lowest point on the LAC.
Explanation:
The costs of all factors of production become variable in the long run. But in the short-run, some costs are variable, and some are fixed. When the producer starts operating over the long run period, it can then operate without the constraints imposed by the presence of the fixed-cost factors. Therefore, in the long run, the average cost (LAC) is equal to the short-run average cost (SAC) because there is an unconstrained minimum average cost at all output levels.

B. the increased expression of a particular trait when a hybrid species is formed.
C. the expression of one gene masking the effects of another gene.
D. quantitative traits that diminish or intensify a particular phenotype.
E. the influence of environment on the expression of a particular genotype.
Answer:
the influence of environment on the expression of a particular genotype.
Explanation:
In genetics, we define penetrance as the proportion of individuals in a given population carrying a particular gene/allele which leads to the expression of the particular trait associated with that gene/allele.
Expressivity is defined as the degree of expression of a given phenotype by individuals who possess a particular genotype. Expressivity shows the extent of variation in expression of genes by individuals having a particular genotype.
Both penetrance and expressivity has to do with the influence of environment on the expression of a particular genotype.
