What molecule carries the message from the axon across the synaptic cleft to the muscle?
Answers
Answer:
Neurotransmitter molecules
Explanation:
(SEE BELOW FOR FULL EXPLANATION ON WHAT NEUROTRANSMITTERS ARE AND WHAT THEY DO)
Chemicals known as neurotransmitters are created by neurons and transferred across the synaptic gap (the empty space between neurons). These chemicals then connect with certain receptors on the surface of the second neuron, causing it to transmit the signal to the third neuron or to have other specific consequences. Keep in mind that synapses are not always between two neurons. They might be situated between a neuron and a gland or a neuron and a muscle.
When molecules have completed their task, they separate from the receptor and are typically metabolized by enzymes. The remainder is then taken up by the first neuron, where it is later utilized to produce new transmitters.
Different neurons generate various neurotransmitters (or other cells). It's noteworthy to note that numerous receptor types with various functions may often be activated by a single kind of neurotransmitter. Many of them also have an impact on the body's other systems and are not just related to the nervous system. Some of the most significant neurotransmitters are listed below:
Adrenaline transmits signals between the neurons that control movement. It also affects other organs, including the heartbeat, respiration, bowel movement, and stomach discharge. It also speeds up the heartbeat and breathing.
Acetylcholine is a chemical that transmits signals from neurons to skeletal muscles. Additionally, it quickens bowel movements, decreases the pulse, and boosts stomach discharge.
Serotonin transmits signals between brain neurons. Its side effects include migraine, nauseousness, and vomiting.
Dopamine's effects include controlling movement, motivation, nausea and vomiting during breastfeeding (sometimes, two substances have the same effect, because neurons, that are responsible for the effect have different types of receptrs, which in this case have the same effect, as they activate the same cells).
Gamma-Aminobutyric Acid is abbreviated as GABA. This one is intriguing since it calms the nervous system and actually reduces cell activity when GABA receptors are activated. For instance, benzodiazepines are medications that work on the same receptors and serve the same purpose as GABA. Their effects—reduced stress, sedation, and sleep—are widely documented.
_________________________________________________
Noting that there are several additional significant neurotransmitters as well as numerous others with less obvious roles, I simply included the most fundamental details for the most fundamental molecules. I hope that makes the key point clearer to you.
Thank you,

how does energy flow trough a forest food chain web from first secondary and tertionary levels
PLS HELP I NEED THIS FOR TMR !!!
Answers
Answer: Primary producer > primary consumer > secondary consumer > tertionary consumer.
Explanation: Primary producers(plants) get their energy from the sun then when a primary consumer (organism that eats plants; herbivores) eats the primary producer it collects that energy with it. Then when the primary producer is eaten by the secondary producer( carnivores that eat smaller animals; such as wolves,crow,hawks etc.). The tertionary consumer eats the secondary consumer.(tertionary consumers are larger carnivores) therefore energy gets passed down the line all the way to the tertionary consumer.
Answer: The energy flow is unidirectional in nature.
Explanation: When these herbivores are ingested by carnivores of the first order (secondary consumers) further degradation will occur. Finally, when tertiary consumers consume the carnivores, energy will again be degraded. Moreover, in a food chain, the energy flow follows the 10 percent law.
A dominant allele is often covered up or masked by the recessive allele. True or false?
Answers
Answer:
Explanation:In a heterozygote, the allele which masks the other is referred to as dominant, while the allele that is masked is referred to as recessive.
Answer:
If the alleles are different, the dominant allele will be expressed, while the effect of the other allele, called recessive, is masked. In the case of a recessive genetic disorder, an individual must inherit two copies of the mutated allele in order for the disease to be present

consider the anatomical differences between bronchi and bronchiole airways. how does the cartilage, smooth muscle, epithelium, and diameter of the two airways differ?
Answers
The bronchi and bronchiole airways differ in their anatomical features such as cartilage, smooth muscle, epithelium, and diameter.
The bronchi are larger airways that contain cartilage rings that provide structural support to keep the airways open during breathing. The smooth muscle in the bronchi is less developed compared to bronchioles.
The epithelium of the bronchi is pseudostratified ciliated columnar that secretes mucus to trap particles and move them out of the airway. The bronchi have a larger diameter compared to bronchioles.
In contrast, bronchioles are smaller airways that lack cartilage rings and rely on the smooth muscle for support. The smooth muscle in bronchioles is highly developed and allows for constriction and dilation of the airways. The epithelium of bronchioles is simple ciliated columnar and secretes mucus to trap particles.
Bronchioles have a smaller diameter compared to bronchi, and the terminal bronchioles are the smallest airways in the lungs.

as blood circulates, it transports inhaled __ from the lungs to body cells and __ from body cells to the lungs to be exhaled.
Answers
As blood circulates, it transports inhaled Oxygen from the lungs to body cells and Carbon dioxide from body cells to the lungs to be exhaled.
Respiration is defined in physiology as the transfer of oxygen from the external environment to the cells within tissues and the removal of carbon dioxide in the opposite direction, that is, back into the external environment.
The biochemical definition of respiration, which refers to a metabolic process through which an organism obtains energy (in the form of ATP and NADPH) by oxidising nutrients and releasing waste products, differs from the physiological definition. Although cellular respiration and the subsequent maintenance of life in animals depend on physiologic respiration, the two processes are distinct: cellular respiration occurs within individual organism cells, whereas physiologic respiration deals with the diffusion and transport of metabolites between the organism and the external environment.

What are the requirements and consequences of crossing over?
1. For crossing over to occur, homologous chromosomes must align precisely early in prophase I so that nonsister chromatids can exchange corresponding segments of DNA.
2. Crossing over occurs at the ends of chromosomes, rather than near the centromeres, because segments of DNA near the centromeres cannot break and rejoin easily.
3. As a result of crossing over, sister chromatids are no longer identical to each other.
4. Crossing over prevents homologous chromosomes from separating during meiosis I.
Answers
Crossing over plays a crucial role in genetic recombination and evolution.
Crossing over is the exchange of genetic material between two homologous chromosomes during meiosis I. Here are the requirements and consequences of crossing over:
Requirements of crossing over: For crossing over to occur, homologous chromosomes must align precisely early in prophase I so that non sister chromatids can exchange corresponding segments of DNA. Crossing over occurs at the ends of chromosomes, rather than near the centromeres, because segments of DNA near the centromeres cannot break and rejoin easily.
Consequences of crossing over: As a result of crossing over, sister chromatids are no longer identical to each other. Crossing over prevents homologous chromosomes from separating during meiosis I. Therefore, crossing over promotes genetic diversity and produces genetically different offspring. It also assists in shuffling genetic information between the two sets of chromosomes inherited from the parents.
On the other hand, if a crossover occurs in a region where two genes are located close together on the same chromosome, it may disrupt the inheritance of these genes.
In summary, crossing over plays a crucial role in genetic recombination and evolution, but it must occur appropriately for genetic inheritance to remain stable. A crossover that occurs between genes, as well as a crossover that occurs outside of genes, could have significant consequences for the genetic inheritance of offspring.

why is surviving on a variety of berries better than relying on a single crop, like rice or potatoes?
Answers
Surviving on a variety of berries is better than relying on a single crop like rice or potatoes because it increases dietary diversity, making it easier to get the essential vitamins and minerals that our bodies need. Berries contain antioxidants, polyphenols, and other nutrients that can help prevent diseases such as cancer and cardiovascular diseases.
Additionally, because berries are seasonal, relying on a variety of them ensures a constant supply of different types of nutrients throughout the year. Furthermore, relying on a single crop can lead to over-reliance on one source of food and vulnerability to food shortages or pest infestations.
By having a range of berries, this vulnerability is reduced. In summary, relying on a variety of berries provides greater dietary diversity, essential vitamins and minerals, and a more secure food supply than relying on a single crop like rice or potatoes.
