antidiuretic hormone (adh) is important in maintaining homeostasis in mammals. adh is released from the hypothalamus in response to high tissue osmolarity. in response to adh, the collecting duct and distal tubule in the kidney become more permeable to water, which increases water reabsorption into the capillaries. the amount of hormone released is controlled by a negative feedback loop. Based on the model presented, what is the relationship between ADH release, osmolarity and production of urine? o As tissue osmolarity rises, more ADH is released, causing less water to be excreted as urine o As tissue osmolarity rises, less ADH is released, causing less water to be excreted as urine o As tissue osmolarity rises more ADH is released, causing more water t0 be excreted as urine o As tissue osmolarity rises, less ADH is released, causing more water to be excreted as urine
0 Two of the above
The relationship between ADH release, osmolarity and production of urine is as tissue osmolarity RISES, MORE ADH is released, causing LESS water to be excreted as urine.
In mammals, antidiuretic hormone (ADH) is essential for maintaining homeostasis. In response to high tissue osmolarity, the hypothalamus releases ADH. The collecting duct and distal tubule in the kidney become more permeable to water in response to ADH, increasing water reabsorption into the capillaries.
Antidiuretic hormone is a brain chemical that causes the kidneys to release less water, reducing the amount of urine produced. When the ADH level is high, the body produces less urine. A low level causes more urine production. Desmopressin is a synthetic form of vasopressin, an antidiuretic hormone. Diabetes insipidus, primary nocturnal enuresis, spontaneous bleeding or haemorrhage, haemophilia A, von Willebrand's disease, and nocturia are all treated with it.

starvation would cause which of the following acid-base conditions? also, determine what type of compensation (metabolic or respiratory) there would be
Option c is the appropriate response. With respiratory compensation, acid-base conditions caused by starvation would result in metabolic acidosis.
Respiration and metabolism are interdependent. Metabolic compensation and respiratory acidosis or alkalosis go hand in hand. Similar to metabolic alkalosis, respiratory compensation is related to metabolic acidosis. Within cells, a process known as cellular respiration uses enzymatic pathways (such as glycolysis and the Krebs cycle) to break down glucose, releasing water, carbon dioxide, and ATP in the process. Direct responses to metabolic demands are made through respiration. The lungs carry out a number of metabolic processes, such as gas exchange, the inactivation of vasoactive chemicals, the conversion of angiotensin I to angiotensin II by the angiotensin-converting enzyme (ACE), and protein synthesis.
Therefore, we can conclude that Option C is the proper response. Acid-base conditions brought on by hunger would lead to metabolic acidosis with respiratory correction.

Wheat is attacked by many different pests, including a fungus called yellow rust.
a Describe how you could use artificial selection to produce a new variety of wheat which is naturally resistant to yellow rust.
When resistant varieties of wheat are produced, it is found that after a few years they are infected by yellow rust again. Explain how this might happen
Answer:Puccinia striiformis f.
Stripe (yellow) rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a serious disease of wheat occurring in most wheat areas with cool and moist weather conditions during the growing season. The basidiomycete fungus is an obligate biotrophic parasite that is difficult to culture on artificial media.
Explanation:Does rust turn black?
Image result
Rust from Iron (III) oxides with limited oxygen and low moisture results in black rust. Black rust can be visually identified as a thin, black film which is the result of oxidation in a low oxygen environment.
There are several fungicides that can be used to protect plants from infection. Mancozeb as a protectant and myclobutanil as an eradicant are generally effective against all rusts while triadimefon is effective against only specific rusts.

4. A car of mass 800 kg accelerates from 5m / s to 25m / s in 10 s. a) Calculate the acceleration. b) Calculate the resultant force exerted.
Answer: To calculate the acceleration of the car, we can use the equation:
acceleration = (final velocity - initial velocity) / time
Plugging in the values given in the question, we get:
acceleration = (25 m/s - 5 m/s) / 10 s = 2 m/s^2
To calculate the resultant force exerted on the car, we can use the equation:
resultant force = mass * acceleration
Plugging in the values given in the question, we get:
resultant force = 800 kg * 2 m/s^2 = 1600 N
This is the force that must be exerted on the car to accelerate it from 5 m/s to 25 m/s in 10 s.
A) As, the accelerarion equation is V - U/t
so its 25-5/10 so its 2m/s^2
B) With the above answer in A) we can calculate the force with the equation f = m * a
so , 800*2 = 1600N

- directional selection
The characteristics of the poppies shifted in response to the changed environment.
This adaptation of the poppies to their new environment is due to directional selection. The characteristics of the poppies shifted in response to the changed environment.
What is directional selection?
In population genetics, directed selection is a mode of negative natural selection in which one extreme phenotype is favored over the other, causing allele frequencies to shift towards that phenotype over time. . Under directional selection, favorable alleles increase as a result of survival and reproductive differences between different phenotypes. The increase is independent of allele dominance and is eventually fixed even if the allele is recessive. First described as a form of natural selection. Other types of natural selection include stabilizing selection and perturbing selection. Each type of selection involves the same principles, but is slightly different. Destructive selection favors both extreme phenotypes distinct from extreme directional selection. Stabilizing selection favors an intermediate phenotype and reduces population variation over time.
