what is the relationship between peripheral resistance and blood pressure ? between blood viscosity and blood pressure
Answer:
Peripheral vascular resistance (systemic vascular resistance, SVR) is the resistance in the circulatory system that is used to create blood pressure, the flow of blood and is also a component of cardiac function. When blood vessels constrict (vasoconstriction) this leads to an increase in SVR.
The relationship between BP and viscosity is such that, given a constant systolic BP, if blood viscosity increases, then the total peripheral resistance (TPR) will necessarily increase, thereby reducing blood flow. Conversely, when viscosity decreases, blood flow and perfusion will increase.

Morgan crossed true breeding red eye (W+), Long leg (SL+) females with true breeding white eye (w), short leg (sl) males. F1 females from this cross were then backcrossed to true breeding white eye (w), short leg (sl) males.
From this cross the following flies were collected:
348 white eye (w), short leg (sl) flies
356 red eye (W+), Long Leg (SL+) flies
68 white eye (w), Long Leg (SL+) flies
55 red eye (W+), short leg (sl) flies
How far apart are the red eye and long leg genes on the X chromosome? (Display your answer in centimorgans, to 2 decimal places.
Answer:
The F1 parents is : W+ SL+/ w sl
The genetic distance is calculated by the(recombinat/total) × 100 = {(68+55) /(68+55+348+356) }×100= (133/837) ×100= 15.89 cM.
Here recombinat are lower in number and parental are greater in number.
15. 89 is the right answer.
4. Does simple diffusion require an input of energy?
Answer:
no
Explanation:
Simple diffusion does not require energy or need the assistance of a transport protein. Other larger or charged molecules that diffuse across a membrane may need assistance from a protein.
The primary source of energy in the cells is a nutrient called
Explanation:
The digestible carbohydrates in an animal's diet are converted to glucose molecules and into energy through a series of catabolic chemical reactions. Adenosine triphosphate, or ATP, is the primary energy currency in cells
The use of arsenate instead of phosphate by glyceraldehyde 3‑phosphate dehydrogenase produces 1‑arseno‑3‑phosphoglycerate. Assume that the presence of arsenate only affects the glycolysis step catalyzed by glyceraldehyde 3‑phosphate dehydrogenase and that 1‑arseno‑3‑phosphoglycerate spontaneously hydrolyzes to form 3‑phosphoglycerate.
How many ATP molecules would a single round of glycolysis consume and produce in this scenario?
Answer:
ATP consumed = 2 molecules
ATP produced = 2 molecules.
Explanation:
Arsenate does not produce 1,3-bisphosphoglycerate, so it can be deduced that at least two ATP molecules are produced through normal glycolysis, remembering that phosphoglycerate kinase allows the reaction between 1,3-bisphosphoglycerate transforming it into 3 -phosphoglycerate and generating two ATP, phosphoglycerate kinase catalyzes this reaction and gives 2 ATP.

Which of the following is an old-world of evolution and no longer valid?
Answer:
Where are the answers?
Explanation:
Anaerobic respiration happens in muscle cells and yeast cells.
The equation describes anaerobic respiration in muscle cells.
glucose ---> lactic acid
How can you tell from the equation that this process is anaerobic?
would the answer just be no co2 is produced?
Answer:
Am I think Co 2 will not be released but rather Glucose will be released
Explanation:
This is because
C6H12O6>2C5H5OH+2Co2 + Energy
there fore glucose is produced
From the equation "glucose → lactic acid," we can infer that the process is anaerobic. One way to determine this is by the absence of carbon dioxide (CO2) in the equation.
Glucose is entirely oxidized to create carbon dioxide, water, and energy during aerobic respiration, which takes place in the presence of oxygen.
Yet, in anaerobic respiration, the lack of oxygen causes an incomplete breakdown of glucose, producing additional byproducts such lactic acid as a result.
Muscle cells have the ability to transition to anaerobic respiration in order to satisfy their energy needs when there is insufficient oxygen.
Muscle cells have the ability to engage in anaerobic respiration, which produces ATP (adenosine triphosphate), the cellular energy currency, by partly metabolizing glucose, during hard exercise or when oxygen supply is constrained.
During anaerobic respiration, lactic acid builds up in muscle cells, which can lead to exhaustion and pain.

What is the advantage for birds of not having a bladder?
Answer:
Explanation:
The urinary bladder is a flexible sac that can expand and contract and that holds urine.
Urea is excreted mainly by birds and it happens to be the main chemical in urine, without the water in it, the birds excrete just solid droppings instead of as a liquid.
Now, birds physiology is such that they have only one opening to get rid of their (solid) waste and they do not have a bladder.

can someone write me a small introduction about reflexes
reflex is an involuntary or automatic, action that your body does in response to something — without you even having to think about it
reflex action often involves a very simple nervous pathway called a reflex arc. A reflex arc starts off with receptors being excited. They then send signals along a sensory neuron to your spinal cord, where the signals are passed on to a motor neuron

Reptiles are a class of vertebrates made up mostly of snakes, turtles, lizards, and crocodilians. The options (A), (B) and (E) are correct.
What are the characteristics of reptiles?Reptiles, as most commonly defined are the animals in the class Reptilia, a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates and rhynchocephalians.
Moreover, the major groups of living reptiles—the turtles (order Testudines), tuatara (order Rhynchocephalia [Sphenodontida]), lizards and snakes (order Squamata), and crocodiles (order Crocodylia, or Crocodilia)—account for over 8,700 species.
Therefore, the name "reptile" comes from Latin and means "one who creeps". All living reptile species are cold blooded, have scaly skin, and lay cleidoic eggs. They excrete uric acid (instead of urea), and have a cloaca. A cloaca is a shared opening for the anus, urinary tract and reproductive ducts.
