Answer:

The correct answer is "production of urea".

Explanation:

The missing options of this question are:

-elimination of urine

-regulation of blood volume

-production of urea

-excretion of excess ions such as sodium or potassium.

The correct answer is "production of urea".

Urea, also known as carbamide, is a nitrogenous compound used by the body to excrete nitrogen that will not be used anymore. The production of urea is not a function of the urinary system, although it is used by the urinary system. Urea is produced in the liver as an end product of a series of biochemical reactions.

Hello, your question is missing its options so I went online to find them.

Here they are:

All of the following processes are functions of the urinary system EXCEPT __________.

A. elimination of urine .

B. excretion of excess ions such as sodium or potassium .

C. regulation of blood volume .

D. production of urea.

Answer:

The correct answer is: D. production of urea.

Explanation:

The urinary system is the system responsible for the filtration of the blood and the elimination of wastes. When blood reaches the nephrons (the structural unit of the kidneys), it is filtered in order to eliminate anything that is not of use. Once filtered, the components that travel through the tubules in the nephrons can be reabsorbed into the bloodstream or have the addition of products that are secreted from the blood and into the tubules for them to be excreted.

The production and elimination of urine are fundamental for the correct functioning of the body, as it regulates the concentration of ions and water, which deeply impacts in the volume and osmolarity of the extracellular fluids such as blood plasma and interstitial fluid. This way, it can be said that the urinary system is responsible for A) the elimination of urine, B) the excretion of excess ions, and c) the regulation of blood volume.

Urea, however, although it has an important role in the reabsorption of water and ions in the nephrons, it is not produced in the urinary system. Urea is a carrier of waste nitrogen.

Answer:

All children will have genotype Ww and phenotype widow's peak.

Explanation:

Widow's peak (W) is dominant over no widow's peak (w). So,

WW, Ww = widow's peak

ww = no widow's peak

Female = homozygous dominant = WW

Male = homozygous recessive = ww

WW X ww :

     W      W

w  Ww   Ww

w  Ww   Ww

All the children will have genotype Ww and phenotype widow's peak.

A homozygous dominant female (WW) and a homozygous recessive male (ww) will have offspring with a genotype ratio of 1:0:0 (WW:Ww:ww) and a phenotype ratio of 1:0 (widow's peak:no widow's peak). This is because the dominant trait (widow's peak) will be expressed in all offspring.

In this scenario, widow's peak is the dominant trait, which is symbolized by 'W', while no widow's peak is the recessive trait, symbolized by 'w'. For the homozygous dominant female, the genotype will be 'WW' and her phenotype will display a widow's peak. Conversely, a homozygous recessive male will carry the 'ww' genotype and his phenotype will display no widow's peak.

When these two mate, all offspring will carry one allele from each parent. All genotypes will therefore be 'Ww', yielding a genotype ratio of 1:0:0 (WW:Ww:ww). The phenotype ratio will be 1:0 (widow's peak:no widow's peak), because the dominant trait of widow's peak will be expressed in all offspring, while the recessive trait, no widow's peak, will not appear.

Explanation:

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.

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.

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:

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: 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.

Explanation:

cellular metabolism is the process in which several chemical recation stakes place in body. there aretwo type of cellular metabolism - catabolism and anabolsim, which serves for several body functions.

During the chemical reaction of cellular metabolism, many acids are produced which are called metabolic acids. Several metabolic pathways produces different acids such as carboxylic acid, citric acid and amino acid. All the metabolic acid maintains body's functional activities,if any case acid formation increases it causes metabloic acidosis.

Hence, the correct option is a. "Metabolic acids are the acid participants of celular metablosim".

Answer:

Uracil, nucleus, amino acid,  RNA

Explanation:

There are four nucleotide bases present in DNA and RNA, three of them ar esame in both that includes Adenine, Guanine and Cytocine but one base is different that includes Thymine in DNA and Uracil in RNA.

In eukaryotes, RNA is transcribed in the nucleus which is transported to the cytoplasm and further translated by the ribososm.

The physical link between tRNA molceules and mRNA , if it is carrying an amino acid. The tRNA molecules matches the amino acids to Codons in mRNA and link with hydrogen bonds.

The ribososme is made of RNA and proteins.

Hence, the sequential order of blanks will be filled with Uracil, nucleus, amino acid,  RNA.

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.

Glucose produced during photosynthesis, provides food for plants and animals in a food web

Explanation:

The main product of photosynthesis is glucose, which is the molecule that produces energy to run the processes of the cell. Oxygen is mainly a byproduct of the process of photosynthesis.

During photosynthesis, plants generate glucose, a type of sugar that serves as food for both the plants and animals in a food web.

The substance that is produced during photosynthesis and provides food for plants and animals in a food web is glucose. Photosynthesis is a process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. In this process, green plants in particular absorb sunlight and take in carbon dioxide and water from the environment to create glucose, which is a type of sugar that serves as a fundamental energy source in living organisms. The plants can then use the glucose for their own energy, or it can be consumed by animals, thereby entering the food web.

Explanation:

The distribution of flower colors in the cross between two lavender plants could be explained by incomplete dominance. This inheritance pattern involves neither allele being completely dominant, resulting in an offspring phenotype that's intermediate between the parent phenotypes. Given this, 25% of offspring flowers will be purple, 50% lavender, and 25% white.

The scenario you're describing with the distribution of 25% white flowers, 50% lavender flowers, and 25% purple flowers in the offspring of two lavender plants could be explained most accurately by incomplete dominance. Incomplete dominance is a form of inheritance where neither allele is completely dominant, and hence the offspring phenotype is somewhere in between the two parent phenotypes.

In your case, the lavender color could be the result of incomplete dominance between white and purple color alleles. If a lavender (heterozygous) plant is crossed with another lavender plant, the Mendelian inheritance expectation would be: ~25% of the offspring will inherit two purple alleles (and be purple), ~50% will inherit a purple and a white allele (and be lavender) and ~25% will inherit two white alleles (and be white).

Explanation:

Directional Selection:

* 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.

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.
