RNA is the nucleic acid that helps build proteins, DNA is the nucleus acid that carries genetic information and the structure of proteins is determined by DNA.
What are nucleic acids?Large macromolecules called nucleic acids are necessary for all organisms and viruses to function. The preservation and expression of genetic data is a key role of nucleic acids. The information cells need to build proteins is encoded in deoxyribonucleic acid, or DNA.
Genetic information is carried by nucleic acids, deoxyribonucleic acid (DNA), and ribonucleic acid (RNA), which are read by cells to create the RNA and proteins that allow living organisms to operate. This knowledge may be duplicated and transmitted to the next generation thanks to the well-known DNA double helix structure.

Which of the answers below best describes the class of questions that Insel and Young were addressing when they studied the effect of antidiuretic hormone on monogamous voles by experimentally increasing the number of receptors in the brain?
proximate; survival-value/adaptation
ultimate; developmental/ontogenetic
ultimate; mechanistic
proximate; mechanistic
Proximate; mechanistic best describes the class of questions that Insel and Young were addressing when they studied the effect of anti-diuretic hormone on monogamous voles.
Explanation:
Genetic researchers, Insel and Young, conducted various studies to analyze the neurobiological aspects of pair bonding on monogamous voles. This was done by studying the changes observed due to the action of the antidiuretic hormone, vasopressin, when their receptors were increased. The transgenic voles exhibited differential gene expressions which explained the proximate and mechanistic mating behavior.
The role of the antidiuretic hormone explained the neurochemical mechanisms of the voles mating behaviors like bonding, attachment etc. Rather than increasing the amount of hormone, just by increasing the receptors of the hormone, male voles showed an increased social reproductive behavior.
Insel and Young's study on the effect of antidiuretic hormone on monogamous voles is classified as a proximate, mechanistic inquiry. It concentrates on the physiological mechanisms that influence behavior.
Explanation:The class of questions that Insel and Young were addressing when they studied the effect of antidiuretic hormone on monogamous voles by experimentally increasing the number of receptors in the brain is best described as proximate; mechanistic. This approach addresses the 'how' questions of biology, focusing on the physiological, genetic, or environmental influences on behavior. In this case, the researchers were trying to understand the physiological mechanisms (antidiuretic hormone and its brain receptors) that influence the social behavior (monogamy) of voles.

When the diaphragm and external intercostal muscles contract, it
Answer:
The correct answer is: lets the air get inside the lungs.
Explanation:
The process of ventilation, or breathing, consists of two parts: inhaling and exhaling.
Inhaling is the name of the process that is responsible for the air entering the body by the respiratory tract. Exhaling is the opposite, it lets the air out. Both are equally important since they allow the gas exchange necessary for the oxygenation of the blood.
When inhaling, the diaphragm and the external intercostal muscles contract. This pulls the ribcage upwards and outwards, which increases lung volume while decreasing the air pressure inside.
Answer:
These are the mechanism of inspiration which increases the capacity of the thoracic cavity, for maximum volume of air to be inhaled during inspiration.
The contraction makes the diaphragm to move towards the abdominal cavity inferiorily creating the space for the distention of lungs during filling with air. When the external inter coastal muscles contracts, the rib cage is pushed upwards and outwards with the sternum remain fixed. This causes expansion of the rib-cage, with further widening of the thoracic cavity for maximum lung capacity.

DNA are RNA are two important components of living body. they have some similiarities and differences as well. They differ in their structure as DNA has double stranded or double helical structure while RNA is single stranded. similarities in the structure of DNA nd RNA is that they both have phosphorus backbone attached with four nitrogenous bases each.
There are three major types of RNA including messenger RNA (mRNA), ribosomal RNA (rRNA) nad transfer RNA (tRNA) functions for serving as temporary copies of the information found in DNA, serve as structural components of ribosomes (protein-making structures) and tranfer amino acids to the ribosome respectively.
Retroviruses are type of virus that carry reverse transcriptase to translate its genetic information into DNA. it inserts a copy of its genome into the host cell DNA and change the genome of that cell. example of retrovirus is human immunodeficiency virus (HIV) that causes acquired immunodeficiency syndrome (AIDS) in humans.
1. In RNA, the nucleotide uracil is used in place of thymine in DNA.
2. In eukaryotes, mRNA is transcribed in the nucleus and then transported to the cytoplasm for translation.
3. tRNA molecules physically link the mRNA message and the amino acid it encodes for.
4. The ribosome is made of proteins and ribosomal RNA (rRNA).
Therefore, the correct blanks for 1, 2, 3 and 4 are uracil, nucleus, amino acid and ribosomal RNA respectively.
Nucleic acids made of nucleotides include DNA and RNA. Their phosphate-sugar backbones are comparable. However, they differ in that they contain different sugars (ribose in RNA versus deoxyribose in DNA) and uracil replaces thymine in DNA in RNA.
There are three main RNA subtypes:
1. Messenger RNA (mRNA): Serves as a template for protein synthesis by delivering genetic information from DNA to ribosomes.
2. Ribosomal RNA (rRNA): constitutes the structural and functional core of the ribosome, which is essential for the production of proteins.
3. Transfer RNA (tRNA) carries amino acids to the ribosome where they are matched to the codons of mRNA during translation.
Retrovirus is an RNA virus that converts its RNA genome into DNA by reverse transcription before integrating that DNA into the host cell's genome. Human immunodeficiency virus (HIV), which causes AIDS, serves as an example. HIV compromises the host's immune system by infecting immune cells.
Therefore, the correct blanks for 1, 2, 3 and 4 are uracil, nucleus, amino acid and ribosomal RNA respectively.

Kendra often has her hair in her hands and pulls at it. When she is nervous, she tends to pull some of it out, which helps her feel better. Most of the time she does not even realize she is doing this. Which diagnosis would Kendra likely receive?
True / False.
Answer:
The correct answer is trichotillomania.
Explanation:
A hair-pulling disorder also termed as trichotillomania refers to a mental condition that comes under Obsessive-Compulsive and associated disorders. The person suffering from the condition has an irresistible desire to pull hair from different parts of the body like eyebrows, scalp, and eyelids.
The condition results in partial or complete removal of the eyelashes and eyebrows, while if one pulls hair from the scalp it can lead to different degrees of hair loss patches. The condition often interferes with the occupational and social functioning of the individual.
Which observation about the phosphorus tracer supported the researchers' conclusion that DNA, and not proteins, transmits genetic information? A. It was in the supernatant only. B. It was in the pellet only. C. It was in both the pellet and the supernatant. D. It was in neither the pellet nor the supernatant.
Answer:
Hershey and Chase demonstrated that genetic material is contained in the DNA molecule. By using bacteriophages they observed that DNA, but not proteins, contains the genetic material. These researchers tagged DNA with radioactive phosphorus and then separated bacteria and protein phages by centrifugation, observing that bacterial pellet was radioactive
The radioactive phosphorus tracer was found only in the pellet (option B), indicating that DNA transmits genetic information.
Explanation:The observation that supports the researchers' conclusion that DNA, and not proteins, transmits genetic information is that the radioactive phosphorus tracer was found only in the pellet, which contained the heavier bacterial cells, and not in the supernatant.
This indicates that the genetic material, which carries information to produce more phage particles, is present in the pellet along with the bacterial cells. Since phosphorus is found in DNA but not proteins, the presence of the radioactive phosphorus in the pellet confirms that DNA is indeed the genetic material.

This is a trait that is a blend of the dominant and recessive gene
Question is incomplete. The complete question is as following:
This is a trait that is a blend of the dominant and recessive gene; inheritance pattern where the phenotype of a heterozygote is intermediate between those of the two homozygotes; neither allele of the pair is dominant but combine and display a new trait.
Answer:
Incomplete Dominance
Explanation:
When two heterozgous alleles are shown together in the phenotype of an organsim, it is called Incomplete dominance. Each allele blend into a third phenotype which produces distinct phenotypes.
In incomplete dominance neither gene is fully recessive or fully dominant. for example Blue-feathered chickens which are produced by the fusion of black and a white chicken and none of the alleles is totally dominant.
Hence, the correct answer is Incomplete Dominance.
Final answer:
Incomplete dominance refers to a genetic situation where the heterozygous phenotype is an intermediary blend of dominant and recessive traits, like in snapdragons' flower color or human hair texture. In genetic crosses, this can be seen when a dominant allele and a recessive allele are expressed together, resulting in a mixed phenotype rather than exhibiting only the dominant trait.
Explanation:
When it comes to inheritance of traits, dominant and recessive genes play a crucial role. Dominant genes mask the presence of recessive genes in the phenotype. However, not all traits follow this simple pattern of dominance. The term incomplete dominance refers to a situation where the phenotype of the heterozygous genotype is a blend of the dominant and recessive traits. This is observed in the flower color of snapdragons, where crossing a red-flowered plant (CRCR) with a white-flowered plant (CWCW) results in pink-flowered offspring (CRCW), indicating an intermediate phenotype. Similarly, humans exhibit incomplete dominance in certain traits like hair texture, where wavy hair results from the combination of an allele for curly hair and an allele for straight hair.
When discussing genetic crosses, such as AaBbcc × AaBbCc or AaBbCc × AaBbCc, the alleles represent various genes that contribute to individual traits. A dominant allele like 'A' will mask the effect of its recessive counterpart 'a' creating a dominant phenotype. Conversely, when there is a recessive allele pair 'cc', the recessive trait will be expressed as there is no dominant counterpart to mask it. In cases of incomplete dominance, a hybrid of alleles, such as 'Cc', would result in a phenotype that is a mix of both traits.

Explanation:
When a muscle is stimulated to contract aerobically, less lactic acid is formed than when it contracts anaerobically because:_____________. 1. glycolysis does not occur to significant extent under aerobic conditions. 2. muscle is metabolically less active under aerobic than anaerobic conditions. 3. the lactic acid generated is rapidly incorporated into lipids under aerobic conditions. 4. under aerobic conditions in muscle, the major energy-yielding pathway is the pentose phosphate pathway, which does not produce lactate. 5. under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.
Answer:
5. under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.
Explanation:
The contraction of muscles occurs in the presence of Adenosine Triphosphate (ATP) because ATP supplies the muscles with the energy they require for contraction.
Muscles can undergo contraction Aerobically ( in the presence of oxygen) or Anaerobically ( in the absence of oxygen).
When a muscle is stimulated to contract aerobically, less lactic acid is formed than when it contracts anaerobically because under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.
The branch of science which deals with a living being is called biology.
The correct answer is E.
The process of breakdown of the glucose molecule into pyruvic acid is called glycolysis. The process of glycolysis is done under the aerobic reaction. The reaction which took place in presence of air is called aerobic reaction.
In this process, Glucose is completely digested into carbon dioxide, water, and energy. Hence, the lactic acid is not formed.
The lactic acid is formed due to a lack of oxygen and leads to incomplete oxidation.
Hence, the correct answer is E that is under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.

According to the oxygen-hemoglobin dissociation curve, PO2 in the lungs of 100 mm Hg results in Hb being 98% saturated. At high altitude, there is less O2. At a PO2 in the lungs of 80 mm Hg, Hb would be ________ saturated. According to the oxygen-hemoglobin dissociation curve, PO2 in the lungs of 100 mm Hg results in Hb being 98% saturated. At high altitude, there is less O2. At a PO2 in the lungs of 80 mm Hg, Hb would be ________ saturated. 95% 100% less than 50% 98%
Answer:
95%.
Explanation:
Oxygen-hemoglobin dissociation curve:
Oxygen-hemoglobin dissociation curve is basically a sigmoid curve which relates between the saturation of oxygen (SO2) and partial pressure of oxygen in blood (PO2). It shows the affinity of oxygen with hemoglobin at different temperature and other factors. In the oxygen-hemoglobin dissociation curve; saturated oxygen is ploted on verticle axis and partial pressure of oxygen in mmHg on the horizontal axis.
Here in the above scenario at the high altitude oxygen is less and at 80 mmHg, Hb would be 95% saturated.

Answer:
A. Striations
Explanation:
Final answer:
A. Striations are grooves or scratches in rocks caused by glaciers. They provide evidence for the direction and force of past glacial movements and are formed through glacial erosion processes like abrasion.
Explanation:
The term that means scratches in rocks caused by glaciers is Striations. These striations, or glacial striae, are lines or grooves cut into bedrock by debris that is carried along the base of a glacier. Evidence of this geological process includes not only the striations themselves but also rock flour, which is finely ground rock produced by glacial abrasion. Glacial striations are a key indicator of past glacial movement and can be found at various scales, from microscopic to several meters in depth and length. They offer clues indicating the direction of ice flow and can be used alongside other features, such as moraines and drumlins, to understand glacial processes.

how do frequency and amplitude affect the motion of the boat? HELP ASAP!!!!!
Answer: Waves are defined as energy transferred from one place to another. The way in which the energy travels is called the medium. These waves can be in the form vibrations through light or matter, such as solid, liquid, or gas (e.g. sound waves or earthquakes). The most important terms in relation to these waves are wavelength, frequency and amplitude.
Wavelength is directly related to frequency because it describes the displacement between the waves, whereas frequency describes how many waves pass within a second. Larger wavelengths are associated with lower frequencies, and smaller wavelengths are associated with higher frequencies.
After a copper smelter begins operation, local populations of plants downwind of the plant begin to adapt to the resulting air pollution. Scientists document, for example, that the acid tolerance of several plant species has increased significantly in the polluted area. This is an example of a response to:________.
a) stabilizing selection.
b) heterozygote advantage.
c) disruptive selection.
d) genetic drift.
e) directional selection.
Answer:
e) directional selection
Explanation:
Directional Selection:
The type of natural selection that favors one of the extremes of the phenotype spectrum, shifting the allele frequency to one directionThis type of selection selects against intermediate and one of the extreme phenotypes. In this particular case, the increasing pollution has pushed the plants to evolve better acid tolerance. This indicates that if the environmental conditions worsen, only the acid tolerant plants will be able to survive.* Another example is illustrated in the image. The graph shows the shifts in allele frequency.
Answer:
Plant species that have increased their tolerance to acid in the presence of environmental contaminants is an example of a response to directional selection (option e).
Explanation:
Directional selection favors a specific trait within some individuals in the population, because they develop greater biological efficiency or have adapted better to environmental changes.
If a graph is made according to the characteristic of "acid tolerance" -where perhaps few plants are tolerant- the presence of a contaminated environment will favor the reproduction and survival of acid-tolerant plants, making resistant plants more frequent in the graph.
Because environmental conditions change, when the change persists over time, an inherited trait -such as acid resistance- is favored, making the population with this trait more frequent.
