Answers

Answer 1

The statement that is not applicable to flocculation or floc formation during waste water treatment is b. Optimal flocculation decreases the amount of BOD (biochemical oxygen demand) entering the effluent stream of wastewater.

In fact, flocculation helps to increase the removal of BOD from the wastewater by facilitating the settling of suspended solids.

Sewer and waste water are treated in four fundamental steps.

a) Screening stage - Grit removal equipment is used to remove big debris and trash from the waste water during this stage of treatment.

b) The initial phase of treatment (physical therapy)

After the screening stage, waste water treatment is subjected to physical processes including aeration, filtration, sedimentation, etc. to remove contaminants.

b) The chemical therapy stage of secondary treatment

Chemicals are employed in this stage to agglomerate minute contaminants into larger masses, making it easier to filter, sediment, and other processes to remove them.  

d) Biological treatment at the tertiary stage

Microorganisms act on waste in this stage, working to eliminate organic contaminants from it whether oxygen is present or not.

Suppose that you perform the cross discussed in Part B: MmDdPp x mmddpp. You plant 1000 tomato seeds resulting from the cross, and get the following results: Use the data to complete the linkage map below. Drag the labels onto the chromosome diagram to identify the locations of and distances between the genes. Use the blue labels and blue targets for the genes; use the white labels and white targets for the distances. Gene m has already been placed on the linkage map.

Answers

The completed linkage map would look like this:

m--(3mu)--d--(2mu)--p.

To create a linkage map, we need to determine the order of the genes on the chromosome and the distance between them based on the frequency of recombination events. From the given data, we can calculate the recombination frequencies between each pair of genes:

m-d: 30/1000 = 0.03 or 3%d-p: 20/1000 = 0.02 or 2%m-p: 10/1000 = 0.01 or 1%m-m: 950/1000 = 0.95 or 95%

Based on these recombination frequencies, we can place the genes in the order m-d-p, with distances of 3 map units (mu) between m and d, and 2 mu between d and p. We can also confirm the location of m at one end of the chromosome, since it has the highest frequency of association with itself (95%).

Which of the classes of RNA molecules carries the genetic information from the nucleus as it is needed for the construction of a protein?
a. ribosomal RNA
b. transfer RNA
c. messenger RNA
d. nuclear RNA

Answers

Your answer: c. messenger RNA. Messenger RNA (mRNA) carries the genetic information from the nucleus as it is needed for the construction of a protein.

Messenger RNA (mRNA) is a type of RNA that carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where it is used as a template for the synthesis of proteins. In other words, mRNA serves as an intermediary between DNA and protein synthesis. During transcription, a segment of DNA is copied into a complementary mRNA strand, which is then transported out of the nucleus and into the cytoplasm, where it binds to ribosomes and provides the template for protein synthesis. The specific sequence of nucleotides in the mRNA determines the sequence of amino acids that will be incorporated into the protein, which in turn determines its function.

Dust mites seem to proliferate in the presence of
a. Dry conditions
b. Use of air conditioners
c. Use of humidifiers
d. Indoor animals

Answers

The use of humidifiers appears to increase the number of dust mites. Here option C is the correct answer.

Dust mites are microscopic arthropods that feed on human skin flakes and thrive in warm and humid environments.  The use of air conditioners can actually help to reduce the humidity in indoor spaces, making it harder for dust mites to survive.

Dry conditions can also be unfavorable for dust mites as they require a certain level of humidity to thrive. In contrast, the use of humidifiers can create conditions that are more favorable for dust mites.

Additionally, the presence of indoor animals, such as cats and dogs, can contribute to the proliferation of dust mites. This is because animal dander, which includes shed skin cells and hair, provides a food source for dust mites. As such, it is important for pet owners to regularly clean their homes to minimize the presence of animal dander and reduce the risk of dust mite infestations.

order of development from fertilization to differentiation of the GI system

Answers

The order of development from fertilization to differentiation of the GI system is a complex and intricate process.

It begins with the fertilization of the egg and sperm, resulting in the formation of a zygote. The zygote then undergoes a series of cell divisions and differentiations, eventually forming a hollow ball of cells called a blastula.

The blastula then undergoes gastrulation, where the cells fold inwards to form a primitive gut tube. This gut tube will eventually give rise to the different regions of the GI system, such as the stomach, small intestine, and large intestine.

As the gut tube develops, different regions begin to differentiate into specific organs and structures. For example, the stomach develops into a muscular sac that churns and mixes food, while the small intestine develops into a highly folded and convoluted structure for maximum nutrient absorption.

The final stages of GI development involve the maturation and specialization of the various cell types within each organ. This includes the differentiation of different cell types within the stomach lining and the development of specialized cells such as the enteroendocrine cells in the small intestine.

Helicase is an enzyme that plays a crucial role in DNA replication by unwinding the double-stranded DNA molecule into two separate strands. This process is essential for DNA replication because it allows the DNA polymerase enzyme to access the nucleotides in each strand and synthesize new complementary strands. Helicase works by using energy from ATP hydrolysis to break the hydrogen bonds between the base pairs in the double-stranded DNA molecule. As it moves along the DNA strand, it separates the two strands of the helix and creates a replication fork, which serves as the starting point for DNA synthesis.

The ubiquitin/proteasome pathway is a complex system of enzymes that work together to identify and degrade proteins that are no longer needed or are damaged. Ubiquitin is a small protein that is covalently attached to target proteins, which signals them for degradation by the proteasome. During the ubiquitination process, a cascade of enzymes adds multiple ubiquitin molecules to the target protein. Once the protein has been ubiquitinated, it is recognized by the proteasome, which is a large protein complex that acts as a molecular shredder.

Point mutations are changes in a single nucleotide of the DNA or RNA sequence, which can lead to changes in the amino acid sequence of a protein if the mutated codon codes for a different amino acid. Mutations can have different effects on an organism, ranging from no effect to causing serious diseases or even death.

The mutated sequence has the codons AUC-GCC-GGC-GAU-UAC-A, which correspond to the amino acid sequence isoleucine-alanine-glycine-aspartic acid-tyrosine. Therefore, the two amino acid changes are from methionine to isoleucine and from threonine to tyrosine.

A. Predation

B. Symbiosis

C. Parasitism

D. Competition

Answers

A particular variety of snapping turtle has a tongue that looks like a worm. Small fish are attracted using the tongue. Predation is the term that best sums up the relationship between the fish and the snapping turtle.

What is Predation?An creature, known as the predator, will kill and consume another organism, known as its prey, in a biological relationship called predation. It belongs to the same family as parasitism, micropredation, and parasitoidism, which are all prevalent feeding habits. Predation most commonly occurs in carnivorous relationships, in which one species eats another. To illustrate, consider wolves hunting moose, owls hunting mice, or shrews hunting worms and other invertebrates. Many little individuals devouring a larger one is a less evident example of carnivorous interactions. When two organisms interact, it's called predation. The predator eats all or a portion of the prey's body. A type of predation called herbivory uses a plant as the prey organism. Population dynamics of the predator and prey have an impact on one another.
