5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.
GivenMass of oxygen at room temperature =500.0 ml
Volume of pressure = 50 atm pressure.
The gas to a volume = 150.0 ml
ExplanationThe volume decreases by the factor = 500.0 mL / 150.0 mL
= 10 / 3
The pressure of the gas increased by a factor of 10/3 , which would make its final value equal to
[tex]P_{final} = \frac{10}{3} * 1.50 atm[/tex]
= 5.00 atm
So, 5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

Dna codes for the sequence of amino acids in the primary structure of a protein, but not for sugars or lipids. This is because?
Proteins are the main structural and functional components of cells.
Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid. The mRNA sequence is thus used as a template to assemble in order the chain of amino acids that form a protein.
The sequence of a protein is determined by the DNA of the gene that encodes the protein change in the gene's DNA sequence may lead to a change in the amino acid sequence of the protein. The sequence of amino acids of a protein determines protein shape, since the chemical properties of each amino acid are forces that give rise to intermolecular interactions to begin to create secondary structures, such as α-helices and β-strands.

What type of control exists in the somatic nervous system?
a. automatic
b. voluntary
c. reflexive
d. partial
e. involuntary
Voluntary control exists in the somatic nervous system.
The somatic nervous system (SNS), or voluntary nervous system is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles.
The somatic nervous system consists of sensory nerves carrying afferent nerve fibres, which relay sensation from the body to the central nervous system (CNS), and motor nerves carrying efferent nerve fibres, which relay motor commands from the CNS to stimulate muscle contraction.
The somatic nervous system consists of two parts:
Spinal nerves: They are mixed nerves that carry sensory information into and motor commands out of the spinal cord.Cranial nerves: They are the nerve fibres that carry information into and out of the brain stem. They include smell, vision, eye, eye muscles, mouth, taste, ear, neck, shoulders, and tongue.Function :
The somatic nervous system controls all voluntary muscular systems within the body, and the process of voluntary reflex arcs.
The basic route of nerve signals within the efferent somatic nervous system involves a sequence that begins in the upper cell bodies of motor neurons (upper motor neurons) within the precentral gyrus (which approximates the primary motor cortex). Stimuli from the precentral gyrus are transmitted from upper motor neurons, down the corticospinal tract, to lower motor neurons (alpha motor neurons) in the brainstem and ventral horn of the spinal cord: upper motor neurons release a neurotransmitter called glutamate from their axon terminal knobs, which is received by glutamate receptors on the lower motor neurons: from there, acetylcholine is released from the axon terminal knobs of alpha motor neurons and received by postsynaptic receptors (nicotinic acetylcholine receptors) of muscles, thereby relaying the stimulus to contract muscle fibres.

What effect did decreasing the extracellular sodium have on the resting membrane potential?
Decreasing the extracellular sodium makes the resting membrane potential disappear. It tends to become less negative. Only a minute change is seen because the resting neuron is not very permeable to sodium.
Sodium is a soft silvery-white metal in nature. In the nerve cells, Sodium (Na+) is critical for the action potential. Action potentials are recursively initiated as the extracellular concentration of Sodium ion Na+ is modified. As the quantity of sodium in the extracellular solution is decreased its action potential decreases as well. Therefore, the quantity of sodium is inversely proportional to its action potential.

Carbon atoms can form
A. one double covalent bond
B. two triple covalent bonds
C. four single covalent bonds
D. three double covalent bonds
Answer:
c
Explanation:
The correct answer is c. four single covalent bonds.
Covalent bondsThe exchange of one or more pairs of electrons between two atoms forms a covalent connection. The two atomic nuclei are drawing these electrons in unison. When there is insufficient space between two atoms' electronegativities for an electron transfer to take place and create ions, a covalent bond is formed. Bonding electrons are shared electrons that are present in the region between the two nuclei. The Covalent bonds pair serves as the "glue" that binds the atoms in molecular structures. To identify the covalent bonds pair from the lone pair electrons, the covalent bond is depicted in a Lewis structure as a dash. The nonbonding electrons in Lewis structures are represented as pairs of dots close to the atomic symbols for the atoms.

What is the effect of each of the 4 types of inhibitors on the initial rate of an enzyme catalyzed reaction?
They are competitive inhibition, non-competitive inhibition, uncompetitive inhibition, and mixed inhibition are the 4 types of enzyme inhibition.
competitive inhibition: The enzyme's active site is occupied by a molecule other than the substrate, which results in competitive inhibition. The substrate and the inhibitor (molecule) are structurally and chemically related (hence able to bind to the active site). The competitive inhibitor blocks the active site to prevent substrate binding.In non-competitive inhibition, a substance binds to a site different from the active site (an allosteric site). The enzyme's active site changes structurally when the inhibitor binds to the allosteric site. This modification alters the affinity between the active site and substrate, prohibiting substrate binding. In non-competitive inhibition, the inhibitor only binds to the substrate-enzyme complex.Uncompetitive inhibition is frequent in reactions involving two or more substrates or products.Mixed inhibition: When an inhibitor binds both the enzyme by itself and the enzyme-substrate complex, mixed inhibition occurs.

Explain how hormones, nervous system stimulation, and the volume, chemical composition, and osmolarity of the chyme affect motility in both the stomach and the duodenum.
Hormones control the different digestive enzymes that are secreted in the stomach and the intestine during the process of digestion and absorption.
Hormones, nervous system stimulation:
The medulla and the vagus nerve both play a role in receptive relaxation, which is when the smooth muscles of the stomach's body and fundus relax to allow the stomach to fill. The strength of the peristaltic waves that stir the chyme is controlled by the vagus nerve and the release of a few hormones (serotonin in the stomach and intestinal gastrin in the duodenum).
Due to a negative feedback loop that slows gastric emptying, motility is slowed when the sensory receptors in the wall of the duodenum detect a high degree of stretch, a low pH, a high lipid content, or a high solute concentration in the chyme. The vagus nerve and the duodenum-secreted hormones secretin, cholecystokinin, and gastric inhibitory peptide mediate this loop.
