A person touches a hot object and immediately moves her finger away from it. Which of the following structures is the first to receive an impulse triggered by the stimulus? and why
A Synapse
B Ventral root ganglion C Motor neuron
D Sensory neuron
E None of the above
The Sensory neuron is the structure that first receives an impulse triggered by the stimulus. Thus, the correct option is D.
What are Sensory neurons?Sensory neurons may be characterized as nerve cells that are activated by sensory input or external stimulus from the environment.
When a person touches a hot object and immediately moves her finger away from it. This is because sensory neurons are activated by an external stimulus, which is sent to the central nervous system of the body, and a motor response is sent out to the skeletal muscles that regulate this movement.
Therefore, the correct option for this question is D.

Complete the following sentences that describe glycolysis and gluconeogenesis in both fed and resting states. After a meal the body is in a fed state, which stimulates the pancreas to secrete the hormone insulin . The plasma membrane receptor on the liver binds to this hormone and activates a signaling pathway that results in the dephosphorylation of the bifunctional enzyme. This event causes a(n) increase in the concentration level of the fructose-2,6-bisphosphate (F-2,6-BP). This new concentration of F-2,6-BP activates the glycolysis pathway. In a fasting state, the pancreas secretes the hormone glucagon . The plasma membrane receptor on the liver binds to this hormone and activates a signaling pathway that results in the phosphorylation of the bifunctional enzyme. This event causes a(n) decrease in the concentration level of F-2,6-BP. This new concentration level of F-2,6-BP. activates the gluconeogenesis pathway, by allowing inhibition of the reciprocal reaction.
Answer:
Fed state - Insulin; dephosphorylation; increase; glycolysis
Fasting state - Glucagon; phosphorylation; decrease; gluconeogenesis
Explanation:
Fructose-2,6-bisphosphate is an allosteric regulator of the enzymes phosphofructokinase-1 and fructose1,6-bisphosphatase-1 which are involved in glycolysis and gluconeogenesis respectively.
After a meal the body is in a fed state, which stimulates the pancreas to secrete the hormone insulin . The plasma membrane receptor on the liver binds to this hormone and activates a signaling pathway that results in the dephosphorylation of the bifunctional enzyme, phosphofructokinase-2/fructose-2,6-bisphosphatase. This event causes a(n) increase in the concentration level of the fructose-2,6-bisphosphate (F-2,6-BP). This new concentration of F-2,6-BP activates the glycolysis pathway.
In a fasting state, the pancreas secretes the hormone glucagon . The plasma membrane receptor on the liver binds to this hormone and activates a signaling pathway that results in the phosphorylation of the bifunctional enzyme phosphofructokinase-2/fructose-2,6-bisphosphatase. This event causes a(n) decrease in the concentration level of F-2,6-BP. This new concentration level of F-2,6-BP. activates the gluconeogenesis pathway, by allowing inhibition of the reciprocal reaction.
2. Which agricultural specialist is most likely to perform research to understand factors impacting the pH of soil?
A. Entomologist
O B. Animal scientist
C. Plant pathologist
D. Agronomist
Answer:
D. Agronomist
Explanation:
Agronomists are professionals that study how to make soils more productive (in terms of food) around the world. Soil pH is an index that calculates the acidity/alkalinity of the soil, which is indicated on a 14-point scale (pH equal to 7 = neutral; pH below 7 = acidic, pH higher than 7 = alkaline). In this regard, it is well known that the pH of the soils drastically affects plant development, and thereby a proper soil pH is fundamental to ensure optimal plant growth (required for nutrient intake). For this purpose, agronomists are in charge of studying and researching the pH of the soils in order to increase crop yields. Nowadays, the pH of the soils can be easily measured by digital soil pH pocket testers that utilize a pH electrode in order to calculate the pH value.

A sporangium (pl., sporangia) (modern Latin, from Greek σπόρος (sporos) 'spore' + ἀγγεῖον (angeion) 'vessel') is an enclosure in which spores are formed. It can be composed of a single cell or can be multicellular. All plants, fungi, and many other lineages form sporangia at some point in their life cycle.

If a physician orders that a patient be given 4 grams of a medication that it is only available in 1000
milligram tablets, how many tablets should the natient hominen?
Answer:
4 tablets
Explanation:
Based on the information in this question, a doctor/physician orders that a patient be given 4 grams of a medication. However, the medication is only available in 1000 milligram (mg) tablets.
Since 1000mg = 1g
This means that one of the available tablet is 1g.
Hence, in order to give exactly 4grams of a 1g tablet, 4/1 = 4 tablets must be given to the patient.

The genetic code is redundant, with more than one codon for some amino acids, and nearly universal—the genetic code is shared by organisms from the simplest bacteria to the most complex plants and animals.
The genetic code is a set of rules that dictates how the sequence of nucleotides in DNA and RNA is translated into the sequence of amino acids in proteins. One of the essential features of the genetic code is its redundancy. There are 20 different amino acids used in protein synthesis, but there are 64 possible codons (combinations of three nucleotides) in the genetic code.
The genetic code is nearly universal. This means that the same codons code for the same amino acids across different organisms, from bacteria to plants to animals. This universality of the genetic code is a strong indication of the common ancestry of all living organisms on Earth. Despite the vast diversity of life, the fundamental genetic code remains highly conserved and shared among all organisms.

What is Nuclear Transplantation?
Answer: Nuclear transfer is a form of cloning. The steps involve removing the DNA from an oocyte, and injecting the nucleus which contains the DNA to be cloned. In rare instances, the newly constructed cell will divide normally, replicating the new DNA while remaining in a pluripotent state.Nuclear transfer is a form of cloning.

Pituitary gland
Cerebrum
Cerebellum
Based on the description provided, the highlighted portion of the brain is the brain stem, which is the first option. The brainstem connects the brain to the spinal cord, and it is located at the base of the brain.
What is the brain?The brainstem is the part of the brain that connects the brain to the spinal cord. It is located at the base of the brain and is made up of three main parts: the medulla oblongata, the pons, and the midbrain.
The medulla oblongata is the lowest part of the brainstem and controls vital functions such as breathing, heart rate, and blood pressure. The pons is located above the medulla and is involved in functions such as sleep, respiration, and facial movements. The midbrain is the uppermost part of the brainstem and is responsible for controlling movements of the eyes and body, as well as processing sensory information.
Hence, based on the description provided, the highlighted portion of the brain is the brain stem, which is the first option. The brainstem connects the brain to the spinal cord, and it is located at the base of the brain.

The following Punnett Square is a monohybrid cross. It takes the genotypes of the parents and predicts the genotypes of their offspring. Fill in the punnett square. Each square will have 2 letters
Answer:
For the 1st block on the left I think there are 2 dominants for that would be BB. The 1st block on the right would be 1 dominant and 1 recessive and that would be Bb. The bottom on the left would be the same as the first block on the right. That would be Bb. The last block that would be the bottom right would be 2 recessives and that would be bb. I hope this might help.
Explanation:
When you are doing punnet squares, you have dominant and recessive traits. There are ways you can do that. If you have 2 alleles of each parent of that offspring, there will be a genotype and a phenotype that represents a genetic trait of each genotype. I hope this helps your question.
