Answer:
a) mucosa, submucosa, hyaline cartilage, adventitia
Explanation:
The wall of the trachea can be divided into four layers from the deep region to the superfacial region :
These are; mucosa, submucosa, the musculocartilaginous layer (hyaline cartilage), and the adventitia.
The adventitia is a connective tissue layer that combines with the musculocutaneous layer and with the connective tissue that encircles the trachea. It is composed of loose areolar tissue. This areolar tissue permits a considerable amount of movement of the trachea along its length.
The musculocartilaginous layer consists of the cartilaginous plates, fibroelastic tissue, and the tracheal muscle. The cartilaginous plates number and are composed of hyaline cartilage surrounded by perichondrium.
The submucosa contains many elastic fibers and fat cells and many small seromucous tubular glands, which open into the lumen of the trachea.
The mucosa has numerous low longitudinal folds and is lined with pseudostratified columnar ciliated epithelium, which contains numerous goblet cells and rests on a basement membrane.
I hope that helps!
Answer:
The correct answer is a) mucosa, submucosa, hyaline cartilage, adventitia.
Explanation:
The trachea is the conduit that allows the passage of air from the outside to the lungs, which is divided at its base into two bronchi.
The walls of the trachea have several layers of tissues, in order from deep to superficial:
Mucosa, has the same goblet cells that contain the pseudostratified epithelia that appear in most of the respiratory tract.
Submucosa, is dense connective tissue and continues with the perichondrium of the hyaline cartilage that constitutes the tracheal rings.
Hyaline cartilage, it is the most widely distributed cartilage. The tracheal cartilaginous ring is open, and the ends are joined by a fibroelastic ligament and bundles of smooth muscle that attach to the perichondrium (the outer layer of cartilage).
Adventitia, is the outermost layer and covers the outer part of the incomplete cartilaginous rings. It is connective tissue that may contain adipose tissue.
Which of the following best describes why invertebrates isn't considered a scientifically valid word when classifying animals? A. The term invertebrates describes all animals, so is not helpful in classifying organisms within the animal kingdom. B. The term invertebrates is unhelpful because all animals possess some sort of backbone or notochord. C. The term invertebrates classifies animals haphazardly based on a missing characteristic rather than a common one. D. The term invertebrates is too vague, since all animals evolved from single-celled organisms without a backbone.
Answer:
Option C
Explanation:
In general vertebrates are organism that has backbone/spine or a vertebral column derived from notochord. While invertebrates are organism that do not have any backbone or vertebra column.
All classification terminologies categorize animals or plants on the basis of some common characteristics. However, in the case of this word invertebrate there is no categorization on the basis of common characteristics, it simply distinguish animals from each other on the basis of presence of backbone/spine/notochord.
Hence, option C is correct

Describe how deep ocean trenches are related to deep ocean ridges.
pls help.
Final answer:
Deep ocean trenches are related to deep ocean ridges through the process of plate tectonics, with ridges creating new crust and trenches marking where old oceanic crust is subducted and recycled into the mantle.
Explanation:
Deep ocean trenches and deep ocean ridges are related through the process of plate tectonics. A deep ocean ridge, such as the Mid-Atlantic Ridge, is an underwater mountain range formed by plate separation where new oceanic crust is created by upwelling magma. Meanwhile, a deep ocean trench is a very long, narrow depression in the sea floor that is typically associated with a subduction zone, which is a type of convergent plate boundary.
As an oceanic plate moves away from a mid-ocean ridge, it ages and cools. Eventually, it becomes denser than the underlying asthenosphere and can be subducted into the mantle at a trench. This destroys old crust at roughly the same rate as new crust is formed at mid-ocean ridges, maintaining a balance in Earth's crustal budget.
Therefore, subduction at ocean trenches is directly related to spreading at mid-ocean ridges, with trenches marking zones where old crust is recycled into the Earth's mantle. This is part of the global cycle of crustal recycling that shapes the Earth's surface over geological timescales.
The term diverticulosis refers to a condition characterized by:_____A. Polyps or growths on the colon wall.B. Inflammation of small pockets in the colon wall.C. Acquired herniations of the muscular colon wall mucosa and submucosa.D. Congenital herniations of the muscular colon wall mucosa and submucosa.
Answer:
C. Acquired herniations of the muscular colon wall mucosa and submucosa
Explanation:
Hernia refers to the development of outgrowth or protrusion of all or part of the organs through their cavity walls or membrane. Diverticulosis is herniation of mucosa and submucosa of the wall of the colon. Diverticulosis is one of the conditions caused by the imbalance of homeostasis. Many sac-like outgrowths develop in the wall of the colon. The outgrowths are in the form of pouches and are called diverticula.
The out-pouching occurs where the muscularis layer of the wall of the colon has weakened. The people with diverticulosis may have no symptoms and no complications. However, when diverticulosis causes inflammation, the person experiences several complications such as pain, vomiting, nausea, etc.
The photos shown below illustrate a case of synpolydactyly, a genetic abnormality characterized by two phenotypes: partially or completely duplicated fingers or toes, and webbing between fingers or toes. The same mutations that give rise to the human phenotype also give rise to a similar phenotype in mice. In which family of genes do you think these mutations occur?
Answer:
Hox gene complex is the set of genes responsible for maintaining the basic body plan of an organism. Synpolydactyly syndrome was the first disorder discovered in human beings that resulted from the mutation in the Hox gene complex. As a result of mutations in the Hox gene complex, syndactyly is inherited, which results in the fusion of fourth and fifth toes and third and fourth fingers.

Blood leaves the glomerulus through a blood vessel called the
The vessel that carries blood away from the glomerulus, a network of capillaries in the kidney, is called the efferent arteriole. This blood vessel is essential in removing waste products and unneeded substances after the process of filtration has occurred in the glomerulus.
Explanation:Blood leaves the glomerulus, a small network of capillaries in the kidney, through a blood vessel known as the efferent arteriole. The function of the efferent arteriole is to carry the blood away from the glomerulus after the process of filtration. Once blood is filtered through the glomerulus, it carries away waste products and unneeded substances. The blood then enters the efferent arteriole, which flows into the peritubular capillaries and continues the process of urine formation.

After transcription begins, several steps must be completed before the fully processed mRNA is ready to be used as a template for protein synthesis on the ribosomes.
Which three statements correctly describe the processing that takes place before a mature mRNA exits the nucleus?
a. Noncoding sequences called introns are spliced out by molecular complexes called spliceosomes.
b. A cap consisting of a modified guanine nucleotide is added to the 5' end of the pre-mRNA.
c. Coding sequences called exons are spliced out by ribosomes.
d. A translation stop codon is added at the 3' end of the pre-mRNA.
e. A poly-A tail (50-250 adenine nucleotides) is added to the 3' end of the pre-mRNA.
Answer:
B
Explanation:
This may be rong, however I think this needs to happen before the mRNA can leave the nucleus. The cap helps prevent the mRNA from being destroyed by the cell itself once it leaves the nucleus.

The time period during which an organ is coming ""on-line"" during pre-natal development is referred to as the:________.
Answer:
Embryonic period
Explanation:
During Prenatal development, the development of an organism takes place in three stages
1) Stage I – When the organism is at the stage I i.e the germinal stage a zygote is formed after a sperm fuses with an egg. The mass of cell move through the fallopian tube and gets embedded in the uterus wall. This process is called implantation.
2) Stage II – In the second stage i.e Embryonic Stage major organs start developing and come in line. After this stage, the embryo is one inch long.
3) Fetal stage – Sex organ, bone, muscle start forming.

The given question is incomplete. The complete question is:
In humans, the maintenance of a stable internal temperature is a direct result of___________.
a. detection of and reaction to stimuli in the environment
b. digestion of starches and absorption of protein from the internal environment
c. diffusion of water and excretion of glucose to the external environment
d. transport of ATP and locomotion through the environment
Answer:
a. detection of and reaction to stimuli in the environment
Explanation:
Thermoreceptors present in skin layers of the human body sense the deviation of the body temperature from the normal range. As the body temperature rises above normal, the thermoreceptors send signals to the brain which n turn signals dermal blood vessels to dilate and sweat glands to secrete sweat. The heat from the body surface is lost to the surroundings to drop the body temperature towards the normal range.
On the other hand, when the body temperature goes below the normal range, thermoreceptors send signals to the brain which in turn signals dermal blood vessels to constrict to conserve the body heat. If body temperature continues to drop, muscles are signaled to contract involuntarily to generate body heat to raise the body temperature towards the normal range.
