Asbestosis is a chronic lung disease caused by inhaling asbestos fibers. prolonged exposure to these fiber causes lung scar-forming fibrous connective tissue.
Asbestosis is serious lung condition which is caused by long term exposure to asbestos. Its a fibrous like material that was once used in building for insulation and roofing. The scarring restricts your breathing and interferes with the ability of oxygen to enter into bloodstream.
It is also called as pulmonary fibrous and interstitial pneumonitis. Fibrous refers to the thickening or scaring of the tissue. In this condition lacy walls of the air sacs in the lungs become thin and lacy but get thick, stiff and scarred which is called becoming fibrotic.

If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the?
If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the muscle.
Although only liver glycogen directly contributes to the release of glucose into circulation, maintaining a healthy blood glucose concentration is one of the glycogen's key functions. Since skeletal muscles lack glucose 6-phosphatase, they are unable to release glucose, and muscle glycogen primarily serves as a local energy source for activity rather than a source of fuel to keep blood glucose levels stable while fasting.
In fact, the breakdown of muscle glycogen into lactate allows for its delivery to the liver, where it participates in the maintenance of euglycemia through the process of gluconeogenesis (Cori cycle).

The rounded superior portion of the uterus that lies between the uterine tubes is called the?
The rounded top portion of the uterus that is situated in-between the uterine tubes is known as the fundus.
A brief explanation of the uterus:
The uterus is the most important hormonally sensitive organ of the female reproductive system in humans and most other animals. The upper region of the uterus, which is above where the fallopian tubes are, is referred to as the "fundus." The region between the corpus and the cervix is known as the isthmus, and it is narrow and situated near the intersection of the internal os of the cervix and the uterine artery.
What does uterine fundus actually mean?
a hollow sphere's area that is opposite or farthest from the organ's opening. Depending on the organ, the fundus might be located at either the top or bottom of a site. The fundus of a uterus, for instance, refers to the upper part of the uterus that lies opposite the cervix.

Cohesin is cleaved by the enzyme ___________, which is held in an inactive state by ___________ until it is degraded by the apc/c complex
The enzyme separase, which is kept dormant by securin until the APC/C complex degrades it, cleaves cohesin.
Discussion about the enzymes:
At the metaphase-to-anaphase shift, the cysteine protease separase cleaves the Scc1 component of cohesin, signaling the start of chromosome segregation. Prior to metaphase, securin, a firmly bound protein, inhibits separase by blocking the separase enzymatic activity with a pseudosubstrate motif. Therefore, we create a technique for creating cloned, securin-free human separase in order to study the affinity and specificity, and control of separase. We find that the Scc1 substrate has an LPE motif that is different from the catalytic domain and necessary for quick and precise substrate breakdown that uses this enzyme. Researchers show that the retained LPE motif found in securin prevents the separase from binding to the Scc1 LPE motif.Learn more about separase here:

When reiko touched her newborn's lips, he produced an automatic response called the _____ reflex
When reiko touched her newborn's lips, he produced an automatic response called the sucking reflex.
What is sucking reflex?These reflexes are uncontrollable motions that might occur on their own or in reaction to other actions. For instance, the sucking reaction occurs when a baby's mouth roof is touched. When this area is stimulated, the baby will start sucking, which aids in nursing or bottle feeding.One of the most crucial reactions your newborn has is undoubtedly the reflex to sucking. It goes hand in hand with the rooting reflex, which is when a baby looks for a food source. The sucking reflex enables him to suck and swallow the milk when he discovers it.The infant will begin sucking when the roof of the mouth is touched. Beginning at the 32nd week of pregnancy, this response takes around 36 weeks to fully develop. Because of this, premature babies may have a poor or undeveloped sucking ability.Learn more about sucking reflex here:

Animalia is a multicellular organism that filters microorganisms from its marine habitat for food and reproduces sexually.
Kingdom Animalia:All kinds of animals are present in Kingdom Animalia. This kingdom's members are all multicellular and comprise eukaryotic cells. They consume other species because they are heterotrophic. Invertebrates like snails and sea anemones and vertebrates like humans and dolphins make up the diversified kingdom of Animalia. They come in all sizes, from blue whales that are 100 feet long to microscopic rotifers.
They have muscle cells, which give them the capacity to relax and contract different body sections. It is sexual to reproduce. However, lesser forms also engage in asexual reproduction.

What enzyme allows h ions to diffuse back across the membrane down their concentration gradient? this process releases energy, what is this energy used for?
What enzyme allows h ions to diffuse back across the membrane down their concentration gradient? this process releases energy, what is this energy used for? ATP Synthase. This proton gradient (gradient of H+) flowing through the membrane enzyme complex ATP synthetase is the direct energy source for producing ATP.
What is ATP synthase?
Adenosine diphosphate (ADP) and inorganic phosphate are used to create the energy storage molecule adenosine triphosphate (ATP) by a protein called ATP synthase . It is categorized as a ligase since it modifies ADP by forming a P-O link (phosphodiester bond). A molecular device called ATP synthase. The overall reaction that ATP synthase catalyzes is:
ATP + H2O + 2H+in ADP + Pi + 2H+out
Energy-wise, the production of ATP from ADP and Pi is undesirable, and the process would typically go the other way. A proton (H+) concentration gradient across the inner mitochondrial membrane in eukaryotes or the plasma membrane in bacteria drives this reaction forward by coupling ATP synthesis during cellular respiration to the gradient.

Administration of testosterone should lead to male mating behavior in an animal only if The requisite sexually dimorphic nuclei are sufficiently masculinized.
The main sex hormone and anabolic steroid in guys is testosterone. In humans, testosterone is essential for the growth of the testes and prostate, as well as for the promotion of secondary sexual traits including increased bone and muscle mass and the development of body hair. Through territorial aggression, wooing rituals, and mate-guarding behavior, high testosterone levels have been found to improve mating effort.

The midtarsal joints and the forefoot's movements are controlled by the STJ, which converts the rotatory forces of the lower extremities.
Before creating a biomechanical functional orthosis, doctors frequently take a cast impression of a patient's foot in the subtalar neutral position.
However, numerous tests have demonstrated that no single approach for determining STJ neutrality is accurate and repeatable.

Pollution originating from a single, identifiable source, such as a discharge pipe from a factory or sewage plant, is called point-source pollution. The term "biological oxygen demand" refers to the quantity of oxygen needed to allow aerobic bacteria to decompose waste organic matter in water.
The need for oxygen decreases as you travel away from the sewage spill and then increases. The need for oxygen decreases as there is more raw sewage present. Fish cannot survive in water with dissolved oxygen levels below 4 gm/liter, and the level will continue to drop.
