Answer:

Sacrum is the bone.

Explanation:

Answer:

C. Sacrum

Explanation:

The axial skeleton makes up the bones along the central system of the body, while the appendicular skeleton comprises the bones along the appendages of the body (in other words, arms, feet, legs, etc).

The clavicle is the collarbone; scapula is shoulder blade bone; and ilium is the hip bone. Of the four choices, only the sacrum, which is at the base of the spinal cord, is located along the central axis of the body and is thus part of the axial skeleton.

C is the answer.

Mutations in slc7a9 could have a greater effect on the transport of cystine, due to its direct role in the transport process, as compared to slc3a1, which mainly contributes to the stability and function of the transporter. The impact may be greater in slc7a9 mutations as it directly alters the protein's primary structure, therefore greatly affecting the transport function.

The hypothesis that mutations in slc7a9 have a greater effect on the transport of cysteine across the plasma membrane of kidney cells than mutations in slc3a1 could be evaluated by observing functional changes in cysteine transport in cells with respective mutations. Both SLC7A9 and SLC3A1 are associated with cystine-uria, a condition characterized by the impaired transport of cystine and related amino acids in the kidney cells.

However, the SLC7A9 gene specifically codes for a subunit of a transport protein that is directly involved in cysteine transport, whereas SLC3A1 codes for a subunit that is needed for the stability and function of the transporter but does not directly mediate transport. Therefore, logically, a mutation in SLC7A9 would have a greater impact on cysteine transport than a mutation in SLC3A1. This is because the primary structure of the protein is directly affected in SLC7A9 mutation, thus greatly hampering the transport process as compared to SLC3A1 mutation.

Mutations in SLC7A9, which encodes the light subunit directly involved in amino acid transport, are hypothesized to have a greater effect on cysteine transport in kidney cells compared to mutations in SLC3A1, the gene for the heavy subunit providing structural support. To evaluate this hypothesis, genetic analysis and functional studies of the transporters, as well as clinical observations, would be necessary.

SLC7A9 and SLC3A1 are genes that encode different subunits of a protein transporter responsible for the renal reabsorption of amino acids, such as cysteine, in the kidney tubules. Mutations in these genes are associated with cystinuria, a condition characterized by the impaired transport of cysteine, leading to the formation of cystine stones in the urine. Since the transport of cysteine across the plasma membrane is a complex process involving both subunits, it is essential to evaluate their roles in maintaining the functionality of the transporter.

One would hypothesize that a mutation in SLC7A9, which encodes the light subunit, might have a more significant impact on cysteine transport due to the direct role of this subunit in amino acid transport. In contrast, the SLC3A1-encoded heavy subunit is thought to mainly provide structural support and potential indirect regulation. Considering each subunit's function, mutations in SLC7A9 could be more detrimental to cysteine reabsorption and lead to more severe symptoms of cystinuria compared to mutations in SLC3A1.

However, to evaluate the hypothesis regarding the impact of mutations in these genes, experimental studies including genetic analysis, protein function assays, and clinical data from patients with these mutations would be needed. It may be discovered that the loss of the support function from the SLC3A1 subunit also greatly impairs the overall transporter function, leading to significant effects on cysteine transport.

Answer:

alveoli → bronchus → trachea → larynx → pharynx → nose

Explanation:

Final answer:

Carbon dioxide exits the body via the respiratory system, moving from the alveoli to the nose through the bronchus, trachea, larynx, and pharynx.

Explanation:

The path of carbon dioxide as it exits the human body follows the reverse path of inhaled air during respiration. The carbon dioxide travels out of the body through the following route: alveoli
→ bronchus → trachea → larynx → pharynx → nose. This process begins in the lungs after gas exchange, where blood deposits carbon dioxide into the alveoli. The carbon dioxide then moves up the respiratory tract, passing successively through the bronchus, trachea, larynx, and pharynx before exiting through the nose.

Answer:

anaerobic respiration does not require oxygen

Anaerobic respiration, which occurs without the need for oxygen, is an essential process for certain prokaryotes like bacteria and Archaea. This process, which often involves the Krebs cycle, is found in all animals and plants and occurs in the cytosol.

The type of cellular respiration that does not require oxygen is anaerobic respiration. This process, sometimes known as fermentation, uses a molecule other than oxygen as the final electron acceptor. It often occurs in prokaryotes, including Bacteria and Archaea, and commonly involves an intact Krebs cycle, also known as the citric acid cycle, to extract energy from carbohydrates. This anaerobic cellular respiration process occurs in the cytosol and can be found in various types of organisms, including all animals and plants.

One alternative to aerobic respiration is anaerobic respiration. In this process, an inorganic molecule other than oxygen, like nitrate, is used as a final electron acceptor in the process of metabolism without oxygen. An example would be methanogens, a group of archaeans, that reduce carbon dioxide to methane to oxidize NADH, ensuring the continuation of glycolysis. These microorganisms are commonly found in soil and in the digestive tracts of ruminants, such as cows and sheep.

Final answer:

The inability of hybrid animals from a goat and sheep mating to reproduce is an example of a postzygotic barrier, which involves sterility or reduced viability in hybrids due to significant genetic differences.

Explanation:

A farmer mates a goat and sheep together, but the resultant hybrid animals cannot have offspring of their own. This scenario exemplifies a postzygotic barrier, one of the mechanisms of reproductive isolation in genetics. Postzygotic Isolating Mechanisms come into play even if fertilization is successful; they operate through genetic differences that become significant enough that the hybrids display reduced viability or fertility compared to the parental species. A common manifestation of this barrier is sterility in hybrids, as seen in mules who are unable to produce offspring despite being bred from a horse and a donkey. This type of reproductive isolation underlines the critical role genetic compatibility plays in the viability of offspring in cross-species breeding attempts.

Marble forms from limestone through a process called metamorphism, which involves heat, pressure, and chemical reactions. Impurities in the limestone can give marble its colorful markings. Marble is mined from quarries and used for construction and art due to its durability.

Explanation:

Marble is formed when limestone undergoes a process of metamorphism, which is the transformation of rocks due to heat, pressure, and chemical reactions. During this process, the calcite or dolomite in the limestone is recrystallized, resulting in the formation of marble. Impurities in the limestone can give marble its colorful markings.

The metamorphism of limestone into marble occurs deep within the Earth's crust. The intense heat and pressure from tectonic forces cause the mineral composition and texture of limestone to change, resulting in the formation of the harder and more compact marble.

Marble is often mined from quarries and used for various purposes, such as building materials and sculptures, due to its durability and aesthetic qualities.

Answer:

D, Venule, vein, heart, artery, arteriole

Explanation:

The squence of blood circulation from the heart, begins with the aorta (artery),(distribution,This push the blood  into  the smaller branches from it callled the arterioles. The lattter are for microscopic distribution into the capillary beds,through the capillaries to reach the cells and the tissues.

The capillaries( containing the anesthetic)  lead back, to empty into  the venules,which are (smaller) subdivision of larger veins. The veins through the superior and inferior vena-cava empty the anesthetic to the heart.

This is pumped by  the heart, through the aorta,and distributed through the arteriole to reach the tissues and cells.

Final answer:

After an anesthetic enters a capillary, it moves to venules, then veins, back to the heart, and is pumped through arteries and arterioles in a continuous cycle.

Explanation:

To understand the journey of an anesthetic or any substance through the circulatory system, it's crucial to know the order in which blood travels through various structures from capillaries back to the heart. After an anesthetic enters a capillary, it moves into small vessels called venules, which then merge into larger vessels known as veins. These veins transport the blood back to the heart. Once in the heart, the blood is pumped to the lungs for oxygenation and then returns to the heart to be pumped out through the arteries. These arteries branch into smaller vessels called arterioles before reaching the capillary networks of various tissues, where the cycle continues.

Therefore, the correct sequence for the journey of the anesthetic would be:

This sequence showcases the path from the smallest vessels after the capillaries back to the heart, and then out to the body's tissues through the arterial system. Option D is correct sequence  .

Plants cannot photosynthesize at night because light is essential for photosynthesis. Plants also need to breath all day.

Answer:Sugar or glucose

Explanation:

Cinsidering definition of photosynthesis, the correct answer is option D. During the process of photosynthesis, green plants produce glucose.

Photosynthesis is a metabolic process carried out by certain cells of autotrophic organisms, that is, those that have the capacity to make their own food, such as plants.

Photosynthesis can be expressed by:

6 H₂O + 6 CO₂ + ligth → C₆H₁₂O₆ + 6 O₂

This implies that to carry out photosynthesis, water (absorbed from the soil through the roots), carbon dioxide and light energy are necessary. Thanks to the chloroplasts, these ingredients are eventually transformed into glucose and oxygen, which is expelled into the atmosphere, while the glucose is used to provide the plant with energy and produce various compounds.

Finally, sunlight, carbon dioxide and water are needed for the photosyntesis, while glucose is produced and oxygen is released to the environment.

Answer:

TRUE

Explanation:

transcription / DNA transcription. Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template.

Final answer:

The statement is TRUE as during transcription, information from DNA is copied to mRNA, which then carries the genetic code to ribosomes for protein synthesis.

Explanation:

TRUE. During transcription, the information on a DNA molecule is indeed copied into an mRNA molecule. Transcription is a crucial process in the flow of genetic information within a cell. This process occurs in the nucleus where the enzyme RNA Polymerase synthesizes a strand of mRNA using the DNA strand as a template. The mRNA strand that is created is complementary to the DNA template strand, following the base pairing rules, with uracil (U) pairing with adenine (A) instead of thymine (T) which is found in DNA.

For example, a DNA sequence ACGGGTAAGG will be transcribed into the mRNA sequence UGCCCAUUCC. The mRNA then carries this genetic code from the nucleus to the ribosomes in the cytoplasm. Here translation occurs, and proteins are synthesized based on the sequence of nucleotides in the mRNA.
