According to the body-cover theory of phonation, which part of the vocal fold is not considered to be a portion of the cover
Answer: B. Thyroarytenoid muscle
Explanation:
The options include:
A. Epithelium
B. Thyroarytenoid muscle
C. Superficial layer of the lamina propria
D. Intermediate layer of the lamina propria
The cover-body theory of vocal fold vibration was published by Hurano in 1974 and he described the morphological structure of the vocal folds. He also divided them into the body and cover layer biomechanically.
The main substance of the vocal fold is regarded as the thyroarytenoid muscle. The muscle provides most of the mass of the vocal cord.

What is the approximate age of the ash footprints at Laetoli? (Hint: what is the radiometric age of Laetoli?)
Answer:
The correct answer is - 3.66 million years ago.
Explanation:
Laetoli, located on the Eyasi Plateau which is known for the remains or footprints of the oldest hominin that were formed and preserved by a series of events - a volcanic eruption, a rainstorm, and another ashfall.
The remains and footprints were discovered at 1978 and are attributed to Australopithecus afarensis. The age of this remaining footprint can be estimated with the help of the radiometric method of the remains which tells that the footprints are 3.66 million years ago formed.

7. Give two examples of biochemical reactions and explain how an organism uses ATP within the reactions.
Answer:
Because of its energy supply, ATP is necessary for all biological reactions.
ATP is employed both in salt and potassium pumping operations and in the cellular breathing mechanism.
Explanation:
The breakdown of glucose, which frees the cell's energy for life functions, is an example of a catabolic response. Endothermic reactions are called anabolic processes in organisms. The connection between amino acids and a protein is an example of an anabolic response.
If a cell needs energy, this link breaks into adenosine diphosphate (ADP) and a free molecule of phosphate... With an excess power of the cell, this energy is stored by creating ATP from ADP and phosphate. For any muscular contraction, ATP is needed for metabolic reactions.
-To break down one glucose into pyruvate molecules in Glycolysis 2 ATP molecules 4 ATP molecules are produced for a net addition of 2 ATP molecules.
-An inorganic carbon is converted into sugar by ATP in photosynthesis.

write in short about medical occupation
A vocation characterized by a specialized body of knowledge of medicine that its members must teach and expand, by a code of ethics and a duty of service that put patient care above self-interest, and by the privilege of self-regulation granted by society.Occupational medicine (also known as “occupational health”) is focused on the treatment of work-related injuries and illnesses. Physicians trained in occupational medicine diagnose and treat work-related injuries much more effectively than most primary care physicians.

The transcription of genes in E. coli that lack a termination sequence require _______ factor to terminate transcription.
Answer:
rho
Explanation:
The Rho factor is a prokaryotic helicase protein that acts in bacteria to mediate the process of termination of transcription. In Escherichia coli, the Rho factor is a hexameric ring-shaped helicase and each subunit of this factor contains two domains involved in RNA binding and ATP hydrolysis. The Rho factor binds to the transcription terminator site on single-stranded RNA and then continues along the messenger RNA (mRNA) strand until it reaches the RNA polymerase, subsequently triggering its dissociation from the DNA and thus the termination of transcription.
A friend who is not taking your Biology course fills a cup with ice and then a drink. The friend asks you why the ice in the cup is floating, and you are able to say that Group of answer choices water vapor is less dense than liquid water. ice is denser than liquid water. convection currents caused by temperature differences push upwards on the ice. the molecules are closer together in ice than in liquid water. the molecules are farther apart in ice than in liquid water.
Answer:
the molecules are farther apart in ice than in liquid water.
Explanation:
The correct answer would be that the molecules of water are farther apart in ice than in liquid water.
Water molecules in ice form are usually less dense than water molecules in liquid form. The water molecules in ice usually arrange themselves in a lattice form, unlike the random form in liquid water. This arrangement makes water molecules in ice to be more evenly spread out than in their liquid counterpart. Thus, ice is usually less dense than liquid water and will obey the principle of flotation by floating on water.
The ice in the cup is floating is due to: the molecules of water are farther apart in ice than in liquid water.
The density of a substance is the mass of the substance per unit of its volume. The formula to calculate the density is :
[tex]D = \frac{m}{v}[/tex], where D = density, m = mass of the substance, and v = volume
The density is the factor that determines if a substance will float or sink. The less-dense substance floats whereas, the more-dense object sinks.When water freezes to form ice then water molecules show expansion to create an open cage-like structure.This cage-like structure decreases the density of ice than the water so mass ice will have more volume as compared to liquid water.Thus, the ice floats on water - the molecules of water are farther apart in ice than in liquid water.

Glucose molecules provide energy to power the swimming motion of sperm. In this example, the sperm are changingA) chemical energy into kinetic energy.B) chemical energy into potential energy.C) kinetic energy into potential energy.D) kinetic energy into chemical energy.E) kinetic energy into thermal energy.
Answer:
A
Explanation:
The correct answer would be that the sperms are changing chemical energy to kinetic energy.
In order to power the movement of the sperm cells, chemicals in the form of glucose molecules are hydrolyzed and the resulting energy from the reaction is used to power the movement of the sperm cells. Moving sperm cells possess kinetic energy. Thus, we can say that the chemical energy in the glucose molecules is converted to kinetic energy in the sperm cells.
The correct option is A.

A population of birds lives on a small island. Another population of the same species lives on the mainland. The
distance between the island and the mainland is too great for birds to fly back and forth. Recently, a series of
sandbars and tiny islands have formed between the island and the mainland.
Answer:
The birds can now reach the Island.
Explanation:
The birds can now reach the Island because there is a sandbars and tiny Islands where they can rest for sometime as well as feed on the insects present at that sandbars and tiny Islands. Before these sandbars and tiny islands, the birds can't reach to the mainland due to large distance between Island and mainland so they have no capability to fly such large distance until the tiny Island and sandbars are appeared in the ocean.
Answer: an increase in gene flow between the bird populations

After nervous stimulation stops, calcium ions returning to the sarcoplasmic reticulum prevent ACh in the synaptic cleft from continuing to stimulate contraction True False
Answer:
False.
Explanation:
Neurotransmitter release occurs from the nervous terminal or varicosities in the neuronal axon. When an action potential reaches the nervous terminal, the neurotransmitter is released by exocytose. The molecule binds to its receptor in the postsynaptic neuron, triggering an answer. As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic response. To stop this process the neurotransmitter must be taken out from the synaptic space. There are two mechanisms by which the neurotransmitter can be eliminated:
• Enzymatic degradation/deactivation: There are specific enzymes in the synaptic space, which are in charge of inactivating the neurotransmitter by breaking or degrading it. The enzyme acetylcholinesterase prevents ACh from continuing to stimulate contraction.
• Reuptake: Receptors located in the presynaptic membrane can capture de molecule to store it back in new vesicles for posterior use. These transporters are active transport proteins that easily recognize the neurotransmitter.
