Answer:
1. GTP dephosphorylation
2. hydrolyzed or removed
Explanation:
GDP, (Guanosine diphosphate) is a biological term, that is made of composition including pyrophosphate group, a pentose sugar ribose, and the nucleobase guanine and it is made from GTP ( Guanosine triphosphate ) dephosphorylation by the ribonucleotide reductase. This enzyme is inactive when hydrolyzed or removed, and then eventually bound to its master regulatory pocket.

How does the wheat stem rust fungus harm its host plant?
Answer:
The stem rust fungus produces several different structures during its life cycle. The most obvious of these on wheat are the reddish-colored urediniospores that form on leaves, stems, and heads during the growing season. These spores are spread by wind and infect wheat or barley plants.
Using specific examples, discuss the roles of negative and positive feedback processes that maintain homeostasis.
Answer:
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

What is Ependymal cell?
Answer:
Explanation: Ependymal cell is a type of neuronal support cell the forms the epithelial lining of the brain ventricles in the brain and the central canal of the spinal cord ependymal cells similar to all other neuroglia, are derived from a layer of embryonic tissue known as neuroectoderm.
Ependymal cells are ciliated-epithelial glial cells. It develops from radial glia alongside the surface of the ventricles of the brain and spinal canal.
What is the function of Ependymal cells?The main role of Ependymal cells is formation of CSF.
The CSF refers to cerebrospinal fluid. It is done by movement of sodium ion, chlorine ion and bicarbonate ion from blood to ventricles of brain.
Inside ventricles of the brain, collection of ependymal cells and capillaries together i.e., the tela choroidea form choroid plexus, which produces the CSF.
Thus, Ependymal cells are involved in formation of CSF.

n your lab you are studying the genome of venomous rattlesnakes to find the gene which codes for their venom glands. You have two rattlesnakes, one rattlesnake has a mutation but can still produce venom. You compare his DNA to a normal rattlesnake. What type of mutation has occurred? Normal: AATCGCTACGCACGTCAG Mutated: TATCGCTACGCACGTCAG
Answer:
There are no options but the kind of mutation that occurred by carefully observing both sequences is:
POINT SUBSTITUTION MUTATION
Explanation:
Mutation is any change, whether small or big, in the nucleotide sequence of a gene (DNA). Mutation occurs from time to time in an organism either by a mistake during DNA replication or induced by a mutagen (mutation-causing substance). Mutation can be of different types depending on the effect on the mutant.
In this case of comparing the DNA sequence two rattle snakes, the sequences of the two snakes are:
Normal: AATCGCTACGCACGTCAG
Mutated: TATCGCTACGCACGTCAG
By carefully observing the two DNA sequences, one would realize that the only difference in the two sequences is the first nucleotide base. That is, in the normal sequence, th first base is Adenine (A) while in the mutated sequence, the first base is Thymine (T).
This type of mutation that involves only one nucleotide base is called POINT MUTATION. It can also be noticed that base "A" was changed "T". Hence, this is a type of SUBSTITUTION MUTATION because a single base was replaced by another in the sequence.
A client reports extremely frequent urination, sometimes urinating 10 to 12 times each day.
What fluid balance disorder would be expected with these symptoms?
Answer:
Lack of Antidiuretic hormone.
Explanation:
Antidiuretic hormone is a type of hormone which is responsible for controlling urination. It is produced in hypothalamus which is a part of a brain. Antidiuretic hormone is responsible to tell the kidney how much water in the body should be conserve to avoid dehydration. If less antidiuretic hormone is produced by the body so more urine is produced. Frequent urination is also occurs due to Diabetes insipidus. This disease produce more urination in order to control the concentration of glucose in the blood.

Which two layers are approximately the same age?
core sample 1
core sample 2
Complete question:
Examine the following diagrams. Columns I and II contain rock layers A, B, C, D, E, and F. Both columns were taken from the same dig site at different locations. Which two layers are of approximately the same age? (Note: The diagrams are attached).
Answer:
C and D
Explanation:
Layers C and D apparently contain the same fossilized organisms in the same substrate. Their appearance is very similar. By knowing that certain organisms used to live in a certain period of time, if we find two strata that show the same fossilized organisms, then we can estimate that these two strata are the same age. Fossilized organisms are used to estimate the age of a rocky stratum.
Life history can be illustrated through fossilized organisms trapped or converted into rocks. These fossils are known as index or guide fossils, of animal or vegetal nature, and they can apport information about the rocky stratum in which they are located or incrusted. These fossils are used to determine the age of the rocky sediments or the environmental conditions under which they were deposited.

Answer:
This question lacks options, options are:
A) cerebral cortex.
B) basal nuclei.
C) sensory pathways.
D) motor pathways.
E) All of the answers are correct.
The correct answer is E.
Explanation:
The cerebral cortex processes and filters its information before passing the most relevant aspects to other regions of the brain. Some of these brain regions, in turn, send information back to the cortex. These loops, known as 'feedback systems', are considered essential for the functioning of cortical networks and their adaptation to new sensory information. Neural circuits must first assess the importance of incoming sensory information and then refine how it is processed in the future. Positive feedback, triggered with the purpose of amplifying the response to the initial stimulus, can be compared to a chain reaction or a vicious circle. Few are the functions regulated by this mechanism; rather it is triggered in pathological situations. It is the system by means of which the organism very rarely regulates any of the bodily functions under normal conditions, making the initial stimulus to be maintained and even increased. This type of mechanism is predominantly present in pathological situations: Its constitutive elements are: stimulus, receptor, afferent pathway, integrating center, efferent pathway, effector and response. The response does not have the ability to satisfy the initial stimulus.

Discuss Connell and Slatyer three mechanisms of succession. Start your answer with a definition and an example of what is succession, and describe how succession begins.
Answer:
Facilitation, tolerance and inhibition models
Explanation:
J. H. Connell and R. O. Slatyer stated three different ecological succession models that explain how species composition may change by the effects of disturbances in the ecosystem. These models are as follow:
1- Tolerance model: in this model, the new species don't affect the growth and success of existing species, thereby the process of succession is purely associated with life-history strategies.
2- Facilitation model: only 'ideal traits' found in colonizing species lead to the initial succession. These ideal traits include for example effective mechanism of dispersal, water storage tissues to survive in dry regions, long-term seed dormancy, etc.
3-Inhibition model: Species that appeared during early succession are capable of inhibiting growth of species appeared in later stages, as well as reduce colonizing species abundance.

You palpate a soft, slightly tender mass in the right scrotum of an adult male. You attempt to reduce the size of the mass, and there is no change in the mass size. Your next assessment maneuver is to:________
a. use two fingers to attempt to reduce the mass.
b. palpate the left scrotum simultaneously.
c. lift the right testicle and then compare pain level.
d. transilluminate the mass
Answer:
d. transilluminate the mass
Explanation:
Sometimes, painless hard or tender mass develop in the scrotum of men and can cause testicular tumors.
After detecting a scrotal mass, to reduce the size of the mass, the next assessment required is to transilluminate the mass in which testicles will be appear opaque on transillumination. Transillumination of mass will help to detect the orientation of mass which can be treated further.
Hence, the correct answer is d. transilluminate the mass
If pattern of inheritance is complete dominance what would you expect when a red and yellow fish were crossed
In the question, it is not mentioned that which fish is dominant and recessive, so lets consider red fish is dominant and yellow fish is recessive.
Answer:
In complete dominance, the dominant trait completely masks the recessive trait and the offspring shows dominant characters only.
When a red and yellow fish were crossed, the pattern of inheritance is complete dominance which means the offspring would have dominant characters.
As we considered, red fish has dominant trait so the offspring produced will also have red color as yellow color (recessive) will be masked by dominant red color fish.
