10. A student purchases and weighs 5 pounds of carrots from a local grocery store. She notices that the grocery store constantly

sprays its produce with distilled water. After returning home, she weighs the carrots again and discovers that they weigh only 4.2 lbs. They also no longer seem as crisp and taut. Provide a possible explanation for why the carrots weighed more at the store, based on the information learned in this lab.

Answer:

In this scenario, the carrots at the store was sprayed with distilled water. This caused a net influx of water into it.

Note that when the carrots was sold out, it was removed from the hypoyinic environment (which was a result of spraying the carrots in the store with distilled water) promoting the process of osmosis (movement of water via a semi-permeable membrane from where there is a higher concentration of water to where there is a lower concentration of water)to diffuse water from within the carrot resulting in a resultant wilt and loss of weight.

Family programmes help to reduce the rates of poverty, over population etc.

<h3><u>Explanation:</u></h3>

Family programming is a scientific approach to initiate a control over the reproduction of eligible couples in a particular population. Family plannings are initiated by the government as well as should be adopted by the couples in order to maintain a very healthy relationship as well a healthy population.

Family planning helps to reduce the poverty, hunger, epidemics, sexually transmitted diseases like AIDS etc and improves the maternal health, infant health, reduces maternal mortality rates, infant mortality rate, neonatal mortality rate etc. This uses the basic contraceptive methods as well as different other factors like when to take a baby and all.

Damage to a brain area called the _____ would MOST likely interfere with learning a conditioned fear response to the sight of a
ELEN [110]

Answer:

The options

A)hippocampus

B)basal ganglia

C)hypothalamus

D)cerebellum

The CORRECT ANSWER IS D)

D)cerebellum

Explanation:

Apart from the coordinating process, the cerebellum is involved in motor learning, emotional behavior, and fear memory.

Fear learning is widely shown in the variation of autonomic and somatic responses, as in heart rate and freezing, promoted by a neutral stimulus which could have been formally grouped with a painful one.

Variation or changes of the vermis influences these responses, and its reversible inactivation in the period of consolidation which is seen to impair fear memory.

The neural correlate of cerebellar activities in fear consolidation is shown by a behaviorally promoted long-term rise of synaptic effectiveness and efficiencies among parallel fibers and a Purkinje cell.

Likely synaptic variations after fear conditioning are well fully observed in the amygdala and hippocampus, suggesting an interplay among emotional circumstances of scenario and the different variations in neural process.

Furthermore, in hotfoot mice, that shows a basic lack of parallel fiber to Purkinje cell synapse, short- and long-term fear memories are influenced.

All these data gives a foundational background on the concept that the cerebellum is majorly involved in fear learning.

The functional interplay of the vermis with hypothalamus, amygdala, and hippocampus do infer to a more complex activities of the cerebellum as a form of an united network that basically influences emotional behavior.

What are the keys to a strong lab procedure?​
Natali5045456 [20]

Answer:

Purpose: A brief description of why the experiment is being performed. Include details about the experiment, such as the methods used, a specific chemical reaction(s), and/or anticipated product.

Hypothesis: Provide a statement or two about the anticipated outcome of the experiment.

Experimental Procedure: A step-by-step description of the experiment including the chemicals, equipment, and/or methods used. Complete sentences must be used for the description. DO NOT simply copy the procedure from a lab manual or a handout. Condense the given procedure into steps so that you can understand and follow them.

Laboratory Safety: Give a complete, descriptive listing of the safety precautions, hazards, or other safety procedures that are needed for this experiment.

Experimental Data: Record all data resulting from the experiment in your laboratory notebook. The experimental data should be recorded in tabular form. Do not record your experimental data in your laboratory manual.

Observations: This section is used to record any qualitative observations and notes on the changes to the experimental procedure. Sudden bursts of scientific insight or other information during the experiment that may aid in the interpretation of the data generated are to be entered in this section. No points will be awarded when the observations are recorded outside of the laboratory. It is also important that you record your unknown number in this section of your notebook.

Calculations: Present outcome/summary of data analysis using tables, Excel graphs, and/or figures. List separately all pertinent mathematical equations followed by a sample calculation for each. Use the recorded data from the experiment when performing the calculations.

Results/Discussion: Questions that should be addressed in this section may include: Did the experiment work, and if not, why not? Were the results obtained in the experiment those expected based on the laboratory procedure? If the experiment was to be repeated, what improvements would be made? What types of errors occurred and how could they be corrected? How did the observations play a role in the outcome of the experiment? When applicable, you should compare your experimental value(s) to that of a published, literature value(s), commenting on the accuracy of your technique.

Conclusion: Summarize the findings of the experiment, which must include the final results of the experiment, e.g., the percent yield of a reaction, the identity of an unknown, etc. Look back at the purpose and hypothesis of your experiment and assess whether or not you met your goal in performing the experiment.

References: Include all pertinent information such as, your laboratory manual, textbooks, web sites, and any other library resources used in the preparation of your laboratory report.
