The USDA has been following hormone use in the cattle industry since the 1950s. The hormone is given to the cattle in pouches inserted into the ear. The hormone enters the bloodstream of the animal very slowly, and according to the USDA the hormones never enter the human food chain. According to the USDA the use of growth ho
What is the temperature coefficient? What is the appropriate equation for the temperature coefficient? Why is it relevant to animal physiology? What does it tell us about ectotherm metabolic rate and temperature?

1. Think about an arthropod such as an ant, and a vertebrate such as a lizard. what functions do the skeletons of there animals have in common? do they have a common structure? Explain. 2. Why do you think that spongry bone has an outer layer od compact bone? 3. Think about the possibible movements of your lower arms
I'm trying to figure out, of what benefit are a closed circulatory system, closed digestive system, an excretory system, and a nervous system, to higher animals?
I have to explain in detail the advantages of why animals live socially in groups and the advantages.
In a lab we looked at the effects of different temperatures on the rate of oxygen consumption and nitrogen excretion in the goldfish. we found that oxygen consumption and nitrogen excretion both increased as the temperature increased. What are some reasons for these increses in oxygen consumption and nitrugen excretion with in
Is it fair (correct) to state that environmental temperature exerts more significant effects on oxygen consumption and ammonia excretion in poikilotherms than endotherm animals? Why?
List the levels of organization of the body, in order of incresing complexity, beginning with the cell.
What physiological states or traits (eg. feeding, exercise, aestivation) may affect the nitrogen excretion rate and oxygen consumption in the goldfish?
Is oxygen consumption the ideal indicator for the metabolic rate in all animals under all circumstances? why or why not?
I'm conducting an experiment entitled the "Effect of volume on Carassius auratus growth". However, I'm uncertain of how often and how much to feed the gold fish. My experimental setup consists of a ten gallon tub (30 X 20 inches, about 6 inches deep) with five individual containers within, approximately filling a volume of 2 lit
I'm having trouble understanding the Assimilation and Production Efficiencies for Endotherms and Ectotherms. How do you determine which has the most efficiency?
Please only take this problem if your answer can not be complete and understandable. Thank you! Describe the storage and release of triglycerides of adipose cells on a molecular level, and describe the hormonal control of this process.
If the activity of phosphodiesterase was blocked, how would a cell be affected if it normally responded to hormonal stimulation through a second messenger system? Be specific.
Please help!!!! I need to know how to do this and I need a complete example of what is written below. I am lost trying to do this!!!! Please do not take this if you can not give me a complete detail answer for this question. It needs to be complete, and I need to be able to get a true understanding of what is involved in this. T
Some marine animals drink salt water, they excrete the extra salt through glands that produce a salty liquid. what transport process must be involved in moving the salt from the blood and into the gland? does this require energy?
I am doing a seminar on the adaptation of the bird respiratory system to flight, but I am having some trouble finding journals that are useful to me. I need to find a minimum of 3 primary resources. I was just wondering if someone could help me find some.
This job aims to discuss the impact the mammalian grade of organization has had on the evolution of the biosphere.
Individual chi square questions 1. The data below was gathered in the Animal Behaviour lab. In this case, 5 zebra danios were placed in a container in compartment A of the aquarium and 5 goldfish were placed in a container in section C of the aquarium. The test fish, in this set of data was a zebra danio. Does this fish displ
You find that out of 20 of red wolves released, 18 survive, and out of 10 brown wolves released, 4 survive. What is the relative fitness of red and brown wolves? I have the fitness of the red wolves (favored genotype?) as 1, but I keep getting a negative number for the brown wolves' fitness.
155 wolves 65% are red wolves 35% are brown wolves -- all carry brow allele 48% of red wolves carry recessive brown allele What is the probability that a wolf carries brown allele? These areas are encompassed.
What is the main form in which carbon dioxide is transported in the blood?
What is the taxinomical classification of the coquerel's sifaka (lemur)? Ideas and links are given.
Aerobic efficiency and fitness can be estimated using the following formula: INDEX = (Duration of exercise in seconds) x100 = 2(sum of first 3 pulse counts in recovery) Norms below 55 = poor 55-64 = low average 65-79 = average 80-89= good 90+= excellent
Behaviors of physiological adaptations that allow a small desert mammal to survive severe drought conditions include all of the following except: The absence of sweat glands Inactivity during the day The production of nearly dry feces The use of water derived from the metabolism of food The excretion of ammonia i
What the three primary vesicles in the amphibian brain and what are their primary functions?
Is the cerebellum in the pigeon larger or smaller than that of the shark?
Discuss one way in which each of the mantle, the foot and the shell have diverged in the oyster, terrestrial slug and squid since these taxa shared a common ancestor. For each change that you mention, briefly indicate how this change reflects the different lifestyles of the oyster, slug and cephalopod.
How is oxygen and carbon dioxide transported and exchanged throughout a grasshopper and clam?
