Method of transmission of blastomycosis dermatitidis
Answers
Both humans and animals can get systemically infected with blastomycosis dermatitidis. The fungus' spores are inhaled into the lungs, which causes infection.
It is possible for the yeast cells to spread to other organs like the skin, bones, and central nervous system once they enter the lungs and begin to thrive there. The characteristic of sickness are granulomas, which are collections of immune cells that encircle and attempt to contain the fungal cells. Although the pathophysiology of blastomycosis dermatitidis is complex and poorly understood, it is thought to be brought on by a variety of virulence factors, including adhesion molecules, body-produced enzymes, and components of cell walls. How the immune system responds to the infection is crucial in determining how the sickness will develop.

Determine if the following statement is true or false and why. “Primary and Secondary Consumers lose about 30% of the energy they absorb from food as heat.” A. False, it should read “Only Secondary Consumers lose about 30% of the energy they absorb from food as heat.” B. False, it should read “Primary and Secondary Consumers lose about 5% of the energy they absorb from food as heat.” C. True D. False, it should read “Primary Consumers lose about 5% of the energy they absorb from food as heat, while Secondary Consumers lose 30% as heat.”
Answers
True. The correct option is C.
Energy transfer in the ecosystemEnergy is transferred from lower to higher trophic levels of the food chain in any ecosystem.
In other words, energy is transferred when primary consumers feed on producers, when secondary consumers feed on primary consumers, and so on.
However, when energy is transferred through feeding from lower to higher trophic levels, a certain percentage of the energy is lost to the surroundings as heat.
In actual fact, scientists believe that about 90% (and not 30%) of the energy is lost as heat to the surrounding. Only about 10% of the energy is converted to useful energy.

No corpus luteum is present and high inhibin concentration in the plasma has suppressed progesterone synthesis is the best explanation for low level of progesterone.
A new corpus luteum is formed with each ovulation and breaks down as soon as it is no longer needed to produce progesterone. Without the corpus luteum, the uterus cannot make the changes necessary for a fertilized egg to become a fetus.
Inhibin is a protein secreted by male Sertoli cells and female granulosa cells. It inhibits the synthesis and release of follicle-stimulating hormone in the pituitary gland and reduces LH-releasing hormone levels in the hypothalamus.

describe what effects different hormones would have on blood pressure (ADH, ANH, Renin)
Answers
Answer:
Antidiuretic hormone (ADH): ADH is produced by the hypothalamus and released by the pituitary gland. It works by increasing water reabsorption in the kidneys, which can increase blood volume and therefore increase blood pressure. This can be helpful in situations where blood pressure is low, such as in cases of dehydration or hypovolemia.Atrial natriuretic hormone (ANH): ANH is produced by the heart in response to increased blood volume and pressure. It works by promoting the excretion of sodium and water in the urine, which can decrease blood volume and therefore decrease blood pressure. This can be helpful in situations where blood pressure is too high, such as in cases of hypertension or heart failure.Renin: Renin is produced by the kidneys in response to low blood pressure or low blood volume. It works by converting angiotensinogen into angiotensin I, which is then converted into angiotensin II. Angiotensin II is a potent vasoconstrictor, which means it can narrow blood vessels and increase blood pressure. It can also stimulate the release of aldosterone, which promotes sodium and water reabsorption in the kidneys, leading to increased blood volume and blood pressure. Renin is an important part of the renin-angiotensin-aldosterone system, which helps regulate blood pressure.Explanation:

Answers
The specific innate behavior being described in this scenario is homing behavior. Homing behavior is the ability of an animal to return to a specific location or home base after navigating long distances away from it.
In the case of salmon, they are able to migrate thousands of miles in the ocean, but they are able to use various cues such as magnetic fields, chemical cues, and visual landmarks to navigate back to the specific location where they were hatched. This behavior is critical for their survival and reproductive success as it allows them to return to the spawning grounds where they can reproduce and ensure the continuation of their species.
Understanding the mechanisms and cues involved in homing behavior in salmon is important for conservation efforts and fisheries management. Researchers study this behavior to gain insights into how different animals navigate and find their way back to specific locations in their environment.

The hormone ____________ stimulates widespread vasoconstriction, release of ADH from the posterior pituitary, as well as the release of aldosterone from the adrenal cortex.
Answers
The hormone responsible for the described physiological effects is angiotensin II. Angiotensin II is produced when the enzyme renin cleaves angiotensinogen, which is released by the liver, in response to decreased blood pressure or decreased blood flow to the kidneys.
The vasoconstriction caused by angiotensin II helps to increase blood pressure, while the release of antidiuretic hormone (ADH) from the posterior pituitary and aldosterone from the adrenal cortex promote water retention and sodium reabsorption, respectively, helping to increase blood volume. These combined effects help to restore blood pressure and improve perfusion to vital organs, especially during periods of decreased blood flow.
The hormone angiotensin II stimulates widespread vasoconstriction, release of ADH (antidiuretic hormone) from the posterior pituitary, as well as the release of aldosterone from the adrenal cortex. Angiotensin II is a key component of the renin-angiotensin-aldosterone system (RAAS), which plays a crucial role in regulating blood pressure and fluid balance. Vasoconstriction increases blood pressure by narrowing blood vessels, while ADH and aldosterone help maintain proper fluid levels and electrolyte balance in the body. These combined actions ensure the body maintains homeostasis and proper blood pressure to support overall health.

what is the major function of the hormone produced by the cells marked in the thyroid follicle shown in the histology picture?
Answers
The thyroid follicles are structures found in the thyroid gland, which is located in the neck.
The cells within the thyroid follicles are responsible for producing and secreting thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3).Thyroxine (T4) is the main hormone secreted by the thyroid gland. It plays a crucial role in regulating the body's metabolism, growth, and development. T4 is relatively inactive compared to triiodothyronine (T3), which is the more biologically active form of the hormone.Once secreted, T4 is converted into T3 in various tissues throughout the body. T3 acts on almost every cell in the body, influencing processes such as energy production, protein synthesis, and gene expression.Overall, the major function of the hormone produced by the cells in the thyroid follicles is to regulate metabolism and contribute to the proper functioning of various organs and systems in the body.
