Houseflies do not transmit diseases by sucking blood from a human host.

So correct answer is  b) houseflies.

While mosquitoes and fleas are known to transmit diseases to humans by sucking their blood, houseflies do not have the necessary mouthparts to pierce the skin and suck blood. However, houseflies can still transmit diseases to humans through other means, such as by landing on and contaminating food or surfaces with their feces or regurgitated fluids. To reduce the risk of disease transmission from houseflies, it is important to practice good sanitation and hygiene habits, such as keeping food covered and disposing of garbage properly. Mosquitoes and fleas, on the other hand, can transmit a variety of diseases, including malaria, dengue fever, West Nile virus, and plague, among others.

Answer:

 true

Explanation:

It is true that enzymes are proteins that accelerate the rates of chemical reactions.

Enzymes are specialized proteins that function as biological catalysts in living organisms. A catalyst is a substance that speeds up a chemical reaction without being consumed or permanently changed in the process. Enzymes are vital for almost all biological processes because they accelerate the rates of chemical reactions necessary for life.

Enzymes work by lowering the activation energy of a reaction. Activation energy is the energy required to initiate a chemical reaction and break the existing bonds in the reactants. In the absence of enzymes, many chemical reactions would be too slow to sustain life because of their high activation energy barriers. Enzymes facilitate reactions by creating a favorable environment for the reaction to occur, promoting the interaction between reactant molecules, or stabilizing the transition state of the reaction.

The Calvin cycle produces a versatile chemical compound called G3P which can be converted to many carbohydrates, as well as fatty acids and amino acids.

Compared to animal cells, both algal and plant cells have enormous capabilities to produce organic molecules through the Calvin cycle.

One of the organic molecules produced from Calvin cycle products is G3P most often metabolized to produce ATP, which is the molecule used by heterotrophs for energy.

Glucose phosphate can be combined with (and the phosphate removed) to form sucrose, the molecule plants use to transport carbohydrates from one part of the plant to the other.

Glucose phosphate is also the starting point for the synthesis of starch, which is the storage form of glucose in plants. Some of this stored glucose is found in chloroplasts, but most is found in the roots of plants.

Glucose phosphate is used to build cellulose, a structural component of plant cell walls that is called fiber when ingested by humans, because we are unable to digest it.

A plant can use the hydrocarbon skeleton of G3P to form fatty acids and glycerol, which are combined in the familiar food products known as plant oils. Also, when nitrogen is added to the G3P hydrocarbon skeleton, amino acids are formed.

Answer:

The model appears to show the carbon dioxide molecules entering the blood cell and the oxygen molecules existing the cell.

Answer:

Explanation:

The model doesn’t clearly show that gas exchange happens in the alveoli through the capillaries. The model can also be easily misinterpreted. Because the model doesn’t show where this gas exchange is taking place, it looks like the blood picks up oxygen, delivers it to the body, and then comes back and expels the carbon dioxide it collects. Clarifying that this gas exchange is taking place in the capillaries would eliminate this confusion.

The common in the musclies is that The cells of smooth, cardiac, and skeletal muscle are all called muscle fibers. (D)

Smooth muscle, cardiac muscle, and skeletal muscle are three types of muscle tissue found in the human body. While they have some differences in structure and function, they all share the common characteristic of being composed of elongated cells called muscle fibers.

Smooth muscle is found in the walls of organs such as the stomach, intestines, and blood vessels. It is not striated, meaning it does not have the alternating light and dark bands seen in skeletal and cardiac muscle fibers. Smooth muscle cells are typically uninucleated, meaning they have one nucleus per cell.

Cardiac muscle is found in the heart and is responsible for pumping blood throughout the body. Like skeletal muscle, it is striated, but unlike skeletal muscle, it is involuntary, meaning it contracts without conscious control. Cardiac muscle cells are uninucleated and are connected by intercalated discs, which allow for synchronized contraction of the heart.

c) Sidewinder rattlesnake is a predator of the cottontail rabbit.

d) Keyhole limpet and scale worm have a symbiotic relationship where they protect each other.

e) Giant armadillo and giant anteater are competitors because they both feed on ants.

Simple answer:

When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. Warmer water temperatures can result in coral bleaching. ... This is called coral bleaching. When a coral bleaches, it is not dead.

More in depth explanation:

Exposure to higher (100 and 1000 µg l-1) diuron concentrations for 96 h caused a reduction in ΔF/Fm¹, the ratio variable to maximal fluorescence (Fv/Fm), a significant loss of symbiotic dinoflagellates and pronounced tissue retraction, causing the corals to pale or bleach.

The expected outcome for the F1 generation is that all plants will be b. all tall. therefore option b. all tall is correct.

According to Mendel's first law, also known as the law of segregation, each individual has two copies of each gene, and these copies segregate during gamete formation, so that each gamete receives only one copy of each gene.

Therefore, in the cross between a tall plant (TT) and a short plant (tt), all the F1 plants will be heterozygous (Tt) because they inherit one tall allele and one short allele from their parents.

In this case, the dominant allele for plant height is "T" (tall), while the recessive allele is "t" (short). The Tt heterozygous plants will have the dominant "T" allele expressed and be tall, as the dominant allele masks the expression of the recessive "t" allele.

Therefore, the expected outcome for the F1 generation is that all plants will be tall.

The approximate volume of each cell is \(10^-10\) L/cell or \(10^-7\) mL/cell. The volume of each cell can be estimated by dividing the volume of the tube by the number of cells present.

If the density of the packed cells is \(1*10^10\) cells/mL, and the volume of the tube is V (in mL), then the number of cells in the tube is given by:

N = density * V =\(1 * 10^10\) * V .

The volume of each cell can then be estimated as the total volume of the tube divided by the number of cells:

Volume of each cell = V / N

= V / (\(1 * 10^10\)* V)

= 1 / (\(1 * 10^10\))

= 1 / \(10^10\)

=\(10^-10\) L/cell

or \(10^-7\) mL/cell. This is an approximation, and the actual volume of each cell may vary slightly depending on the size and shape of the cells and other factors.

b. scientists can modify viral DNA

d. viruses can direct cells to make specific proteins

The primary reason why viruses are used to deliver therapeutic genes to target cells is that they have the natural ability to enter cells and deliver genetic material. However, this ability can also cause harm to the host organism. Therefore, scientists modify the viral DNA so that it can safely deliver therapeutic genes without causing harm. Additionally, viruses can be engineered to direct cells to make specific proteins, which can be beneficial for treating various diseases. Therefore, options (b) and (d) are correct. Option (a) is incorrect because although viruses can enter cells, they cannot be directly injected into cells. Option (c) is also incorrect because viruses do not carry many beneficial genes; rather, they can be engineered to carry specific therapeutic genes.

When treated with pepsin, the oligopeptide ALKMPEYISTDQSNWHHR would yield two peptide fragments. Cleavage occurs between the phenylalanine (F) and leucine (L) residues, resulting in fragments ALKMPEYISTDQSNW and HHR.

Pepsin specifically cleaves peptide bonds following aromatic amino acids (phenylalanine, tryptophan, and tyrosine) and certain amino acids like leucine, methionine, and glutamic acid. Analyzing the given oligopeptide, we can identify potential cleavage sites. Pepsin would cleave after the phenylalanine (F) residue, resulting in two fragments: ALKMPEYISTDQSNWHHR.

Therefore, the answer is "2" peptide fragments. The cleavage takes place between the phenylalanine (F) and the following leucine (L) residues. This would yield two separate peptide fragments: ALKMPEYISTDQSNW and HHR. The first fragment ends with the last amino acid cleaved, while the second fragment starts from the cleavage site and continues until the end of the oligopeptide.

Shipwreck victims are strongly advised against drinking seawater due to its high salt content and potential detrimental effects on the human body. Seawater contains approximately 3.5% salt, primarily composed of sodium chloride.

Consuming saltwater can lead to severe dehydration and exacerbate the already dire situation of being stranded at sea.Drinking seawater does not quench thirst but instead has the opposite effect. When saltwater is ingested, the high salt concentration draws water out of the body's cells through osmosis, further dehydrating the individual. This can lead to increased thirst, dizziness, nausea, and eventually organ failure.

Moreover, the kidneys play a vital role in maintaining fluid balance by filtering waste products and excess salts from the blood. Drinking seawater places a tremendous burden on the kidneys as they attempt to excrete the excessive salt, potentially leading to kidney damage and further dehydration.

Ultimately, the consumption of seawater is strongly discouraged as it accelerates dehydration, compromises kidney function, and worsens the survival prospects of shipwreck victims. It is essential to prioritize obtaining fresh water from alternative sources if available or conserving resources until rescue or assistance arrives.

In ChIP-seq (Chromatin Immunoprecipitation followed by sequencing), the DNA in the supernatant and the DNA in the pellet differ in terms of their association with proteins and chromatin structure.

During the ChIP-seq procedure, the first step involves crosslinking and shearing of the chromatin to break it into smaller fragments. These fragments consist of DNA regions associated with proteins, including transcription factors, histones, and other chromatin-associated proteins.

After the chromatin is sheared, an antibody specific to the protein of interest is used to immunoprecipitate the protein-DNA complexes. The immunoprecipitation process allows the antibody to selectively bind to the protein, thereby pulling down the protein-DNA complexes from the mixture.

Following immunoprecipitation, the samples are centrifuged to separate the immunoprecipitated complexes from the rest of the mixture. The centrifugation results in the formation of a pellet and a supernatant.

The DNA in the pellet contains the protein-DNA complexes that were pulled down by the antibody. These complexes consist of the DNA regions that were associated with the protein of interest. The protein-DNA complexes are then washed and eluted to release the DNA from the protein, resulting in the DNA that can be further analyzed for sequencing.

On the other hand, the DNA in the supernatant represents the DNA fragments that were not associated with the protein of interest. These fragments were not pulled down by the antibody during immunoprecipitation and remained in the supernatant after centrifugation.

The key difference between the DNA in the supernatant and the DNA in the pellet is their association with the protein of interest. The DNA in the pellet is enriched for regions that were bound to the protein, while the DNA in the supernatant represents the unbound or non-specifically bound DNA fragments.

In ChIP-seq analysis, sequencing and subsequent bioinformatics analysis are performed on the DNA in the pellet to identify the genomic regions that were bound by the protein of interest. These regions are indicative of potential regulatory elements, such as transcription factor binding sites or histone modification sites, which can provide insights into gene regulation and chromatin structure.
