Are phenotypic ratios are always the same as genotypic ratios?
Expected phenotypic ratios are always the same: 3:1. Expected genotypic ratios are always the same: 1:2:1.
Is is true that bones always stay the same size?
No. Bones are always changing, but the length usually stays the same all your adult life.
What is Sympathomedullary pathway?
neurons fromthe symathetic system (SNS) go to to almost every organ and gland within the body. The parasympathetic system (SAM) at the same time as the sympathetic system (SNS) is activated. The SAM system alerts the animal (whatever it it is) through the release of adrenaline into the bloodstream and together these two systems make up the SYMPATHOMEDULLARY PATHWAY.
Decay always happens at the same rate in ecosystems?
decay always happens in ecosystems
Sugar is converted into carbon dioxide during what process in the body?
Tissue respiration in animals where an ATP molecule is used to release energy, and at the same time it produces carbon dioxide.
Why might an individual experience the phenomenon known as referred pain?
Visceral pain afferents travel along the same pathway as somatic pain fibers
What is a closed pathway where the start and end points are the same?
A closed pathway where teh start and end points are the same is called an electric circuit.
Why does buses in London has number and letters?
Buses with the same destination don't always travel the same route to get there.
Does everyone have the same ratio of carbon-14 to stable carbon in their bodies?
No, some people who live in higher elevated areas tend to have more carbon 14 because it doesn't have to travel farther down to where people live.
Carbon 12 and carbon 13 are different in the number of what?
Neutrons. The number of protons is ALWAYS the same for the same element. Different forms of the same element, called isotopes, differ in the number of neutrons only and will react chemically in exactly the same way.
Does light always travel at the same speed?
The speed of light is always the same as long as it's traveling through the same medium. But its speed is different in different media, and those are all less than its speed in vacuum.
How far does a loggerhead sea turtle travel?
Sea turles can travel thousands of miles in their lifetime, but always return to the same beaches to lay their eggs, year after year.
What does it mean to have a definite chemical composition?
It means that the proportions of each element in the compound are always the same. Put another way, the formula is always the same. Water is always H2O because it is made (composed) of two hydrogens to one oxygen. If there are different proportions, then it is a different substance, or doesn't exist. H2O2 is hydrogen peroxide, which is very different from water. Carbon dioxide is always CO2, i.e. one carbon to two oxygens, and if there is only one of each, CO, that's the deadly poison carbon monoxide.
What 2 discoveries supported hess' hypothesis?
It can be seen through experimentation that no matter what pathway a reaction takes to reach its final product, the energy change is always the same. For example, to make carbon dioxide from carbon and oxygen we can either go straight from A to Z, or we can go via Q; make carbon monoxide first, then add another oxygen. The path we take does not matter since the overall energy changes will be the same, for a given amount of reagents. This is known as Hess' Law.
How does the ocelot breath?
The ocelot breathes through its nostrils like other mammals. When it inhales, air enters through its nostrils and passes through the nasal passages into the lungs, where oxygen is exchanged with carbon dioxide. The ocelot then exhales, releasing carbon dioxide from its lungs through the same pathway.
Given that action potentials traveling down the axon of a particular neuron are always the same amplitude how is a stronger stimulus communicated to the next cell in the neural pathway?
The strength of a stimulus is coded in the frequency of action potentials, not in the amplitude.
How are carbon and CO2 the same?
Carbon and carbon dioxide, CO2 are not the same. They are not even similar. Carbon is a black solid. CO2 is a colorless, odorless, gas.
