During the swallowing reflex __________. during the swallowing reflex __________. the tongue closes the pharynx breathing rate increases the epiglottis closes the glottis the esophageal sphincter closes the esophagus

Answers

Answer 1
Answer: I believe that during swallowing the epiglottis closes the glottis. Epiglottis is a leaf-shaped cartilage located behind the tongue, at the top of the larynx, whose main function is to seal off the windpipe during eating, so as to prevent accidental inhalation of food. It is only during the process of swallowing that the epiglottis moves and performs this vital function.

Too much water in spaces surrounding cells is known as _________.a. osmosis
b. ions
c. edema
d. cations

Answers

The answer is c. edema.

Edema is a condition in which there is too much water in spaces surrounding cells. It results when blood vessels are leaky, so a fluid from blood vessels enters the nearby tissue. This extra fluid accumulates and, thus, tissue swells.

Ion is an atom or a molecule with a net charge, either positive (cation) or negative (anion). Osmosis is the movement of solvent molecules from a higher solute concentration to a lower solute concentration.

Contraction of the muscle that is attached to the radial tuberosity results in

Answers

Answer:

Bending or flexion of the forearm and elbow

Explanation:

Radial tuberosity, alongside head and neck, is one of the important landmarks of the radius. It is a bony projection on the middle side of the radius where the tendons of the biceps branchii muscle insert itself.

In Anatomy, Radial tuberosity can be found at the center right of the left elbow and the upper left of the left forearm when the palm is facing upward.

The contraction of the biceps branchii muscle results in the flection or bending of the forearm and elbow

why it is important to know the speed of earthquake waves, the strength of the waves and how do we determine the location of the epicenter of an earthquake. ?

Answers

Answer: As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.

Which pair of organisms show convergent evolution?

Answers

A convergent evolution is a phenomenon of independent evolution of similar traits in species that are in different lineages. These traits are similar in form or function but were not present in the last common ancestor of those species.
There are many examples of convergent evolution among plants and animals. Among the plants, both cactus and euphorbia are succulent plants, have spines, live in the deserts, but they belong to the different families. Further, dolphin, which is a mammal, is more similar to fish, than to other mammals. Or, both birds and bat, which is the mammal, have wings. So, all these examples of convergent evolution suggest that the living in the similar environmental conditions led to development of similar forms between distinct species.

An allele whose trait always shows up in the organism when the allele is present.

Answers

The allele whose trait always shows up in the organism when the allele is present is called dominat allele.

What is a dominant feature?

The dominant term is related to the genetic transmission of a trait and is represented, in biology, by a capital letter (A, B or V). While recessive, represented by a lowercase letter (a, b or v), they represent genetic traits transmitted only in the absence of the dominant gene.

We say that an allele is dominant when it manages to determine a phenotype, even if it occurs in a single dose. This means that the dominant allele will express itself in both homozygosity and heterozygosity. Dominant allele is expressed in the phenotype, even in a single dose.

Which type of circulation explains the movement of blood from the heart to the lungs and back to the heart again?

Answers

Pulmonary circulation is the type of circulation that explains the movement of blood from the heart to the lungs and back to the heart again.

Blood that does not carry oxygen originates from the heart and moves to the lungs where it is filled with oxygen. Oxygen filled blood from the lungs travels back to the heart where the oxygen is used up.
As your heart beats, it brings up blood through a system of blood vessels called the blood circulatory system, the vessels that are in your body are elastic tubes that carry blood to every part in your body. oh and the type of circulation is Arterial and these blood vessels carry blood away from your heart through the elastic tubes. The Arterial blood vessels helps the blood circulate through your body with an constant flow.....
