Kelvin is pitching for his high school baseball team. he has mastered the art of the curveball, and knows just how to twist his fingers around the seam of the baseball to make the pitch work. the part of the nervous system that helps him feel the seams on the baseball and control his fingers to throw the curveball properly is the __________ nervous system.
The correct answer is the somatic nervous system. It is because the SNS or also known as the voluntary nervous system is the one responsible for controlling the voluntary movements of the body in which is through the skeletal muscles. This is the likely reason that helped Kelvin feel the seams on the baseball and control his fingers to throw the curveball properly.
Rachel had injections of botox in an attempt to eliminate facial wrinkles. botox contains minute amounts of botulin, an extremely lethal substance produced by bacteria, and works by blocking the release of a specific neurotransmitter from motor neurons, causing muscle paralysis. this neurotransmitter, found in all motor neurons, is called:
Final answer:
Botox contains botulinum toxin, which blocks the release of the neurotransmitter acetylcholine from motor neurons, leading to muscle relaxation and the reduction of wrinkles.
Explanation:
Rachel had injections of botox with the goal of eliminating facial wrinkles. Botox contains small amounts of botulinum toxin, which is a potent neurotoxin produced by the gram-positive bacterium Clostridium botulinum. The substance works by blocking the release of a crucial neurotransmitter from motor neurons, causing temporary muscle paralysis. This neurotransmitter, which is found in all motor neurons, and is responsible for muscle contractions, is called acetylcholine. When botox is injected in controlled, minute quantities, it prevents the release of acetylcholine, allowing muscles to relax and reducing the appearance of wrinkles. The use of botulinum toxin has been approved for both cosmetic and medical treatments, including the removal of wrinkles, treatment of overactive bladder, and other conditions such as cervical dystonia and excessive muscle contractions due to neurological conditions.
Connecting the concepts: levels of biodiversity what are the levels of biodiversity, and how are they valuable? part a drag the labels onto the concept map to review the ecological value and practical benefits of biodiversity. first fill in the pink targets using the pink labels. then complete the rest of the concept map using the blue labels. ecosystem diversity species diversity ecosystem services species survival genes with practical uses genetic diversity community interactions new medicines
The levels of biodiversity include ecosystem diversity, species diversity, and genetic diversity. Ecosystem diversity refers to the variety of ecosystems present, while species diversity refers to the variety of different species. Genetic diversity refers to the variety of genetic material within a species. Biodiversity is valuable because it provides ecosystem services, supports species survival, and offers genes with practical uses.
Explanation:Levels of Biodiversity:1. Ecosystem diversity:
Ecosystem diversity refers to the variety of ecosystems present in a particular area. It includes different types of habitats, such as forests, wetlands, grasslands, and coral reefs. Ecosystem diversity is valuable because it provides a range of services that support human well-being, including clean air and water, climate regulation, and nutrient cycling.
Species diversity refers to the variety of different species within a particular ecosystem or on the entire planet. It is measured by counting the number of different species present. Species diversity is valuable because each species plays a unique role in maintaining ecosystem function. It also provides opportunities for scientific study, as well as aesthetic and recreational enjoyment.
Genetic diversity refers to the variety of genetic material within a species. It is important for species survival because it enables populations to adapt to changing environments. Genetic diversity is also valuable because it can be used in various practical ways, such as developing new medicines or improving crop plants.
Biodiversity provides a wide range of ecosystem services that are essential for human well-being. These services include the provision of food, clean water, and raw materials, as well as the regulation of climate, disease, and natural disasters.
Biodiversity is crucial for the survival of species. As species interact with one another in ecosystems, they rely on each other for food, shelter, and other resources. If one species disappears, it can have a domino effect on other species in the ecosystem.
Genetic diversity is valuable because it provides a source of genes that can be used for practical purposes. For example, genetic diversity in wild plants can be used to breed crops with improved resistance to pests and diseases. Genetic diversity in organisms can also be used to develop new medicines.

Another name for crh is ________ factor. cortisol-releasing corticotropin-releasing insulin-releasing glucagons-releasing estrogen-releasing
CRH, also known as the corticotropin-releasing factor, initiates a process resulting in the release of glucocorticoids like cortisol into the blood in response to stress. It does this via the triggering of the release of ACTH, which stimulates the adrenal cortex. This cortisol plays a major role in long-term stress response in the body.
Explanation:Another name for CRH (Corticotropin-Releasing Hormone) is corticotropin-releasing factor. This hormone is released from the hypothalamus in response to normal physiologic rhythms and stress. It triggers the secretion of the adrenocorticotropic hormone (ACTH) which, in turn, stimulates the adrenal cortex to secrete glucocorticoid hormones such as cortisol.
This cortisol has a significant role in long-term stress response, an example being the catabolism of stored nutrients to maintain sufficient fuel supplies in the body; this entails the conversion of glycogen to glucose, stored triglycerides into fatty acids and glycerol, and muscle proteins into amino acids.

An increase in sympathetic stimulation of the heart would increase stroke volume by increasing __________. view available hint(s) an increase in sympathetic stimulation of the heart would increase stroke volume by increasing __________. end diastolic volume heart rate end systolic volume contractility submit
Final answer:
An increase in sympathetic stimulation enhances the heart's contractility, leading to an increased stroke volume. This, along with other mechanisms like an elevated heart rate and vasoconstriction, helps maintain cardiac output and blood pressure during stressful conditions.
Explanation:
An increase in sympathetic stimulation of the heart would result in an increase in stroke volume by increasing contractility. Sympathetic stimulation is known to be a positive inotrope, meaning it increases the force of the heart's contractions. Neurotransmitters like norepinephrine (NE) and epinephrine (adrenaline) are released, which bind to the heart muscle cell receptors and increase the metabolic rate and force of contraction. This leads to a larger volume of blood being ejected with each beat (stroke volume), and a smaller end systolic volume (ESV) is left in the ventricles.
Sympathetic responses, including the release of NE and epinephrine, also enhance both cardiac output and vasoconstriction. During situations such as blood loss, sympathetic responses can also help return blood pressure to normal levels by increasing heart rate and stroke volume which, along with vasoconstriction, work together to maintain blood circulation to vital organs.
Describe how living conditions change for two tidal organisms
Final answer:
In the intertidal zone, organisms like barnacles and seaweeds adapt by cementing themselves to rocks or using holdfasts to avoid being washed away, while other organisms switch between anaerobic and aerobic respiration based on salinity levels.
Explanation:
Organisms in the intertidal zone face significant challenges due to the frequent shifts between aquatic and terrestrial environments, which include changes in temperature, salinity, and the possibility of being washed out to sea. For example, barnacles adapt by cementing themselves to rocks to resist the water's movement, while seaweeds use rootlike structures called holdfasts to anchor themselves firmly. In addition, some organisms, such as bivalves, cease feeding and switch to anaerobic respiration when exposed to low salinity and then resume feeding and aerobic respiration when the conditions become favorable again at high tide.
High tide provides shelter and feeding for barnacles, while crabs forage freely. During low tide, both face desiccation and predation risks.
Certainly! Let's consider two tidal organisms: barnacles and crabs, and how their living conditions change with the tides.
1. Barnacles:
During high tide, barnacles are submerged in water, allowing them to filter feed and gather nutrients from the surrounding water. The water provides them with protection from predators and ensures they have access to food.
However, during low tide, barnacles are exposed to the air. This can be challenging as they are at risk of desiccation (drying out) and predation. To combat this, barnacles have developed adaptations like closing their shells tightly to retain moisture and reducing metabolic activity until the tide returns.
2. Crabs:
High tide provides crabs with ample opportunities for foraging and hunting as they can move freely in the water. The higher water levels also offer them protection from terrestrial predators.
Conversely, during low tide, crabs face different challenges. They may become stranded in tide pools or exposed on the shore, making them vulnerable to predators like birds and larger fish. To cope, crabs often seek refuge under rocks or burrow into the sand to stay moist and avoid predators until the tide rises again.
In summary, the living conditions for both barnacles and crabs fluctuate dramatically with the tides, presenting various challenges and opportunities that these organisms have adapted to over time.
Why don’t poor farmers use the machinery and fertilizers of Green Revolution farming?
A. They misused and broke them.
B. They do not like to use them.
C. They cannot afford them.
D. They are afraid of them.
Final answer:
Poor farmers do not use Green Revolution machinery and fertilizers mainly because they cannot afford them. High costs combined with accessibility issues and uncertainty about weather conditions make these technologies prohibitive for small-scale farmers.
Explanation:
The primary reason poor farmers do not use the machinery and fertilizers of Green Revolution farming is C. They cannot afford them. The Green Revolution brought about an increase in agricultural productivity due to the use of new agricultural technologies, such as powered equipment, synthetic fertilizers, and high yield crop varieties. However, these technologies often required a significant investment that small-scale and poor farmers could not afford. The cost of powered equipment, fertilizers, and improved seeds was beyond the financial capacity of many farmers, particularly in developing countries where access to credit was limited. Additionally, farmers were concerned about the increasing uncertainty of rainfall and erratic weather conditions which could make their investment in these expensive inputs less reliable. Social inequality widened as a result, with small-scale farmers struggling to compete against larger farms that could take advantage of economies of scale.

The daily values (dv) on the nutrition facts panel of a food label differ from the dris. the dv for total fat for a 1,750-calorie diet is 65 g total fat. with rueben's one day intake in this menu, how did his fat intake compare to the dv?
Rueben's daily fat intake can be compared to the Daily Values by totaling the fat content of his consumed food and measuring it against the DV of 65 grams for a 1,750-calorie diet.
The student's question asks how Rueben's actual fat intake over one day compares to the recommended Daily Values (DV) for total fat, which is 65 grams for a 1,750-calorie diet. The % Daily Value on the Nutrition Facts panel helps consumers understand how much of a particular nutrient a serving of food contributes to their overall daily diet, based on a 2,000-calorie diet. In this scenario, without the specifics of Rueben's food intake, a general comparison cannot be made. However, by knowing the amount of fat in each food item Rueben consumed and adding it up to get the total fat intake, one can then compare that to the 65-gram total fat DV. If Rueben's intake exceeds 65 grams, it means his fat consumption is higher than the DV suggests for a diet of 1,750 calories. It's also important to note that the DV is a generalized recommendation and individual needs may vary.
