An anatomy and physiology student, is asked to breathe through a 3-foot long glass tube. What effect does this action have on his blood pH, urine pH, and respiratory rate?
Answer:
If a student breathes through a 3 feet long glass tube it will affect the physiology of the student in various ways such as a change in blood pH, urine pH, and rate of respiration.
It will result in an increase in the normal volume area of the trachea and bronchi as it is a closed system as a face mask. The increase in this dead volume are will result in double the volume of CO2. Decrease the pH of the blood.
When asked to breathe through 3-foot long glass tube there would reduced oxygen available to the tissue (hypoxia) which had the following effects discussed below.
Hypoxia occurs when there is reduced oxygen available to the body tissues.
When asked to breathe through a 3-foot long glass tube, it can lead to hypoxia.
The effect of hypoxia include the following:
Blood pH: Due to increase in anaerobic respiration in the tissues, lactate production increases leading to a fall in blood pH. Urine pH: Hypoxia leads to increase in renal sodium excretion which helps acid-base balance of the body fluid. Respiratory rate: There is significant increase in respiratory rate to compensate for the decreased tissue oxygen levels.Learn more here:

Accuracy in the translation of mRNA into the primary structure of a polypeptide depends on specificity in the ________.a) binding of ribosomes to mRNA.b) binding of the anticodon to small subunit of the ribosome.c) attachment of amino acids to rRNAs.d) binding of the anticodon to the codon and the attachment of amino acids to tRNAs.
Answer:
d) binding of the anticodon to the codon and the attachment of amino acids to tRNAs.
Explanation:
A transfer RNA (tRNA) is one of the three types of RNA molecules whose job is to match an mRNA codon( a sequence of three DNA or RNA nucleotides that corresponds to a specific amino acid) with the amino acid it codes for.
Each tRNA contains a set of three nucleotides called an anticodon which corresponds to the amino acid encoded by a codon of an mRNA. The amino acid encoded by the codon is also attached to the tRNA molecule. This ensures specificity and accuracy during translation.
Therefore, during the translation of mRNA into the primary structure of a polypeptide, accuracy depends on specificity in the binding of anticodon and attachment of amino acids to tRNA.
Which two layers are part of the thermosphere?
exosphere and ionosphere
ionosphere and mesosphere
mesosphere and stratosphere
stratosphere and troposphere
Answer:
The exosphere and the ionosphere
According to the research, exosphere and ionosphere are two layers that are part of the thermosphere.
What is the thermosphere?It is one of the layers that make up the Earth's atmosphere characterized by X-rays, gamma and ultraviolet rays that cause sodium molecules and atoms to ionize, increasing the temperature.
Due to this peculiarity, the thermosphere includes the ionosphere, where ionization processes take place and the exosphere is the layer with the lowest density.
Therefore, we can conclude that according to the research, exosphere and ionosphere are two layers that are part of the thermosphere.

Explain the relationship and importance of different levels of organization in the human body e.g. the cell, tissue, organ, organ system
Answer:
All living and non-living things are made of one or more unique substances called elements, the smallest unit of which is the atom, (for example, the element oxygen (O) is made of O atoms, carbon (C) is made of C atoms and hydrogen (H) is made of H atoms. Atoms combine to form molecules. Molecules can be small (for example, O2, oxygen gas, which has 2 atoms of the element O; CO2, carbon dioxide, which has 1 atom of C and 2 of O), medium (for example, C6H12O6, glucose, which has 6 atoms of C, 12 of H, and 6 of O); or large (for example molecules called proteins are made of hundreds of atoms of C, H, and O with other elements such as nitrogen (N). Molecules are the building blocks to all structures in the human body.
Explanation:
How can the expression of a single gene be quickly, efficiently, and specifically shut down at the transcriptional, posttranscriptional, and posttranslational stages through coordinated expression of a transcriptional repressor, an miRNA, and a ubiquitin ligase?
Answer:
Ubiquitin ligase is a protein enzyme recruits Ubiquitin-conjugating enzyme that come with the ubiquitin and catalyzes the transfer of ubiquitin to the protein substrate of interest and destructed by the proteosome.
miRNA are small RNA molecules with no coding behavior that binds with the mRNA with the help of base pairing of complementary codes. It helps in mRNA degradation and cutting of poly-A tail of mRNA type of gene expressing.
A gene-specific transcriptional repressor helps in preventing the transcription process of the mRNA by inhibiting the binding of the RNA polymerase to the promoter.

In an old experiment, Jean Baptista van Helmont grew a plant in a pot
that he filled with 200 pounds of soil. After several years, the plant
grew to weigh 169 pounds. The amount of soil in the pot did not
change; it still weighed 200 pounds. Based on your knowledge of
photosynthesis, how did the plant gain most of its weight?
A. The plant gained weight by absorbing nutrients from the soil.
B. The plant gained weight by producing oxygen and storing it.
C. The plant used carbon dioxide to make organic compounds like
glucose, which increased the plant's weight.
D. The plant made carbon dioxide from organic compounds like
glucose, which increased the plant's weight.
Answer:
C. The plant used carbon dioxide to make organic compounds like glucose, which increased the plant's weight.
Explanation:
Plants are mostly autotrophic organisms i.e. have the ability to make their own food via the process of photosynthesis. The food, which s in the form of sugars makes up their biomass. Plants use carbon dioxide (CO2) in the presence of sunlight to make organic compounds such as glucose, which is necessary for growth.
Hence, according to this question, the plant in a pot filled with 200 pounds of soil gained weight and increased to 169 pounds because the plant used carbon dioxide in the process of photosynthesis to make organic compounds like glucose, which increased the plant's weight.
A gene carries the _________ for a trait.
Answer:
A gene carries the information for a trait.
Explanation:
Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes.
A gene carries the information for a trait.
What is gene?The fundamental structural and operational component of heredity is a gene. DNA is the component of genes. Some genes serve as blueprints for the synthesis of proteins. Many genes do not, however, code for proteins.
A few hundred DNA bases to more than 2 million bases make up a gene in a human. Humans are thought to have between 20,000 and 25,000 genes, according to the Human Genome Project, an international research project that aimed to decipher the human genome's sequence and catalog its genes.
Every gene is present in two copies, one from each parent, in every individual. The majority of a person's genes are the same in all persons, but a tiny fraction (less than 1% of the total) are slightly different.
Therefore, A gene carries the information for a trait.

Cattle and buffalo share a similar fundamental niche, the entire set of conditions under which a population can survive and reproduce. A realized niche is the set of conditions actually used by a given population. Explain what the data in the Venn diagram suggest about the realized niches of the cattle and buffalo and their ability to coexist. Use evidence to support your explanation.
Answer:
The data in the Venn diagram suggest about the realized niches of the cattle and buffalo and their ability to coexist with evidence is discussed below in detail.
Explanation:
2.
From the graph, it is observed that Cattle and Impala have the most overlay in their nutrition.
3.
When Sorensen's index worth is more like 1, there is a contestant among animals for their food manner needs.
From the Venn diagram, we recognize that Cattle and Impala have the most overlay in their nutrition. Also, Sorensen's index worth = 0.82 (closer to 1 concerning other partners.
4.
Sorensen's index for Buffalo and Cattle is 0.48 (cheapest among these 3 partners). So, they are less competitive. So, they can persist and generate easily.
