However, there was one slight anomaly from the data, which is from the 5th stimulation, the time taken increases when it should have been decreasing.
Pulse rate in mammals.
However, we can reduce this error by having the same person measuring the time taken throughout the experiment. Choose three of the following and for each, explain how feedback mechanisms maintain homeostasis.
A stronger or weaker force will generate different generator potential and thus affecting the reaction time of the snail to re-emerge. The survival of organisms depends on regulatory mechanisms at various levels.
For example, there is one of the famous experiments investigating habituation which is involving the giant sea slug Plays. For 3 of the following 5 processes involving energy transfer, explain how each functions in the cell and give an example.
The arrows indicate reaction sites for two restriction enzymes enzyme X and enzyme Y. The diagram below shows a segment of DNA with a total length of 4, base pairs. A B C Discuss the type of nutrition and the nutritional requirements of angiosperms and vertebrates. Select one of the criteria stated above and describe experimental evidence used to determine that DNA is the hereditary material.
A scientist working with Bursatella leachii, a sea slug that lives in an intertidal habitat in the coastal waters of Puerto Rico, gathered the following information about the distribution of the sea slugs within a ten-meter square plot over a day period.
Dominant 51 Recessive 49 0 80 Total a. They then have to name their polypeptide with a name ending with -in, like most proteins. Structure and function are related in the various organ systems of animals. The day was bright and sunny, and the wind was calm. Is there evidence indicating whether or not this population is in HardyWeinberg equilibrium?
Assume that the digestion occurred under appropriate conditions and went to completion. Habituation allows animals to ignore unimportant stimuli so that the limited sensory attention and memory resources can be concentrated on more threatening or rewarding stimuli.
The shell of a snail is made up of calcium carbonate. HTML Snails are one of the earliest known types of animals in the world. Their data are shown below: By habituating to less important signals, an animal can focus its attention on the most important features of its environment.
On the basis of the data, propose a hypothesis that explains the change in the phenotypic frequency between generation 1 and generation 3. The decrease in time taken for eye-stalk withdrawal is due to habituation.
For two of the following examples, explain in detail how the transfer of information is accomplished. Select two of the following four organ systems in vertebrates: After a while, sensory systems may stop, sending signals to the brain in response to a continuously present or often-repeated stimulus.
The results is recorded in a suitable table and presented in an appropriate graph. By using the techniques of genetic engineering, scientists are able to modify genetic material so that a particular gene of interest from one cell can be incorporated into a different cell.
Thus we might have stopped the stopwatch earlier or later than it supposed to be, causing the result is not accurate. Choose three of the following components of organ systems.
As a result, the post-excitatory generator potential at the post- synaptic neuron membrane is not high enough to reach the threshold level to generate an action potential.
Communication between two plant cells Communication between two immune-system cells Communication either between a neuron and another neuron, or between a neuron and a muscle cell Communication between a specific endocrine-gland cell and its target cell Describe how this classification scheme presents different conclusions about the relationships among living organisms than those presented by the previous five-kingdom system of classification.
For each organism given as an example, describe two reproductive adaptations. Information transfer is fundamental to all living organisms. Explain how each variable could bring about the observed pattern of distribution.2.
A scientist working with Bursatella leachii, a sea slug that lives in an intertidal habitat in the coastal waters of Puerto Rico, gathered the following information about the distribution of the AP Biology 1 Fall Essay Review.
