The primary function of the human digestive system is to break down food into smaller molecules so they can be absorbed into the bloodstream and supplied to the body's cells. Food undergoes both mechanical and chemical digestion in the stomach and intestines, leading to absorption of nutrients.
Explanation:The main function of the human digestive system is B) process organic molecules so they can enter cells. The digestive system begins this process in the mouth where food is broken down mechanically by teeth and chemically by salivary enzymes.
It continues in the stomach where gastric juices break down proteins. After that, in the small intestine, enzymes from the pancreas further break down food, allowing nutrient molecules including carbohydrates, proteins, and fats to be absorbed into the bloodstream.
The digestive system finishes this process in the large intestine, where water and electrolytes are reabsorbed back into the system, essentially leaving waste material that is then excreted via the rectum and anus. Therefore, the principal job of the digestive system is to break down food into tiny molecules and deliver them into the cells to be used as fuel for energy, growth, and cell repair.

A little boy blows air into a rubber glove and ties a knot at the end of it. He realizes that he wants the puffed-up glove to be bigger, but he's already tied a knot that he cannot untie.
According to the gas laws, what could the little boy do to increase the volume of air in the glove?
poke a hole in one of the fingers of the glove
place the glove in the sun
squeeze the fingers of the glove
place the glove in the freezer
squeeze the fingers of the glove because of imcrease pressure
Answer:
Place the glove in the sun
Explanation:
According to the ideal-gas law:
PV=nRT (1)
References:
P= Pressure
V= Volume
T=Temperature
n= Mol
R=Constant
As it is described , the amount of air inside the glove is constant, so R and n are constants and the ideal-gas formula can be re-written as follows:
V=aT/P (2)
Being "a" a constant.
We can see in (2) that the volume can be incresed directly by increasing the temperature or by lowering the pressure. So the correct answer is "place the glove in the sun" because the temperature of the air will be increased and the volume of the glove will be increased as well.
It is easy to think that by squeezing the fingers of the glove the volume is increased, but in this case the volume of the glove is decreased (because it hasn't got the volume of the fingers anymore) and the pressure is increased in consequence, making the rest of the glove swell in order to maintain the original volume.

Final answer:
Learned behaviors are not inherited traits and are not passed from parents to their offspring. These behaviors are developed after birth, influenced by environmental factors and previous experiences, highlighting the adaptive nature of organisms.
Explanation:
The question asks whether learned behaviors are inherited traits, with the correct answer being that learned behaviors are not passed from parents to their offspring and are not inherited traits. Instead, learned behaviors are skills and responses that animals develop after birth, influenced by environmental changes and previous experiences.
This distinction is crucial in understanding the adaptive capabilities of organisms in response to their surroundings. Learned behaviors include imprinting, habituation, conditioning, and cognitive learning, enabling organisms to adapt to environmental changes. Unlike innate behaviors, which are instinctual and genetically programmed, learned behaviors can be modified and are not fixed.
The hand is proximal or distal to the upper arm
Answer:
The further away an attachment or body part is from the center (shoulder, elbow, wrist, hand, fingers) the more distal it is, and the closer the body part is to the center the more proximal it is.
Explanation:
Final answer:
The hand is distal to the upper arm; 'distal' means farther from the point of attachment to the trunk, whereas 'proximal' means closer.
Explanation:
The hand is distal to the upper arm. The term 'distal' refers to a position in a limb that is farther from the point of attachment to the trunk of the body or the origin. In contrast, 'proximal' describes a position that is nearer to this point of attachment. For instance, the brachium (upper arm) is proximal to the antebrachium (forearm). In the context of the human body's anatomical position, the upper arm, which contains the humerus bone, is between the shoulder and the elbow joints, while the hand is beyond the wrist. Therefore, when comparing the position of the hand relative to the upper arm, the hand is situated distally.

Most notably, kidneys remove dangerous toxins and excess water from your blood and eliminate them through your urine. Kidneys also perform other amazing physiological feats, from regulating the amount of fluid in your body to controlling the salt content of that fluid. Here are three more amazing kidney functions.
1. Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.
2. Regulation of osmolarity. The kidneys help keep extracellular fluid from becoming too dilute or concentrated with respect to the solutes carried in the fluid.
3. Regulation of ion concentrations. The kidneys are responsible for maintaining relatively constant levels of key ions including sodium, potassium and calcium.

The function of the light-dependent reactions is to:
a) build sugars
b) capture and transfer energy into a usable source
c) release carbon dioxide
d) form water molecules
Answer:
c
Explanation:
OPTION B. The main function of light-dependent reactions in photosynthesis is to capture and convert light energy into chemical energy (ATP and NADPH), which will then be used to build sugars in the light-independent reactions.
Explanation:The function of the light-dependent reactions, which occur in the thylakoid membranes of the chloroplasts in plants, is to capture and transfer energy into a usable form. During these reactions, light energy is converted into chemical energy, specifically ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). ATP and NADPH are then used in the light-independent reactions (the Calvin cycle) to build sugars.
The other options presented are not primarily functions of the light-dependent reactions. They do not directly form water molecules or release carbon dioxide yet contribute indirectly by capturing energy used in other processes that could involve these functions.

sensory and motor neurons are connected to the ____ nervous system
Answer:
Central
Explanation:
Sensory and motor neurons are connected to the central nervous system.
The central nervous system (CNS) is the section of the nervous system that is made up of the brain and spinal cord. The sensory and motor neurons are connected to the central nervous system. The sensory neurons receive impulses (message) and transmit them from the sense organs to the brain or spinal cord, while the motor neurons transmit impulses from the brain and spinal cord to muscles or glands within the body.
Sensory and motor neurons are both linked to the peripheral nervous system. Sensory neurons transport information from the body's tissues and organs into the central nervous system, while motor neurons transmit signals from the central nervous system to the body's muscles, glands, and organs.
Explanation:
Sensory and motor neurons are connected to the peripheral nervous system. In detail, the peripheral nervous system consists of the nerves and ganglia that lie outside the central nervous system, which includes the brain and spinal cord. Sensory neurons bring information from the body's tissues and organs into the central nervous system, which helps us react to stimuli. In contrast, motor neurons carry signals from the central nervous system to the muscles, glands, and organs in the body to trigger actions like muscle contraction or gland secretion.

According to what you have learned about the circulatory and respiratory systems, explain how and why your heart changed its rate?
Answer:
Your heart changes its rate depending on the activity, so that it can carry blood to your muscles, and therefore it needs to beat stronger if you are performing some exercise, or not so strong if you are sleeping, for example.
Explanation:
Your heart is continuously beating to keep blood circulating throughout your body.
So, here it is why your heart changes its rate: Its rate changes depending on your activity level; it is lower while you are asleep and at rest and higher while you exercise to supply your muscles with enough freshly oxygenated blood to keep the functioning at a high level.
And how: depending on your activity level, your heart has to pump enough blood to your muscles. Blood carries needed oxygen and other nutrients. Muscles need more blood sugar than any other tissue especially when working hard. To supply your muscles with oxygen your heart needs to beat faster, and this builds up your heart muscles.
Final answer:
The heart rate changes due to the autonomic nervous system's regulatory signals, based on the body's oxygen needs. The SA node controls these changes to ensure adequate blood circulation. External factors and the body's physical state directly influence the heart's operating rhythm.
Explanation:
The heart rate changes in response to the body's need for oxygen. During physical activities or stressful situations, the autonomic nervous system signals the heart to beat faster through the Sinoatrial Node (SA node), also known as the heart's pacemaker. This mechanism ensures that more oxygen-rich blood is circulated throughout the body to meet the increased demand.
Conversely, when the body is at rest or calm, the heart rate slows down, reducing the need for oxygenated blood. Factors such as physical fitness levels, emotional state, and even body position can influence heart rate. For instance, shifting from lying down to standing can cause a temporary increase in heart rate to maintain blood pressure and ensure adequate blood flow.
The heart, located within the circulatory system, is the central pump that drives blood through a network of arteries and veins, delivering nutrients and oxygen while removing waste products. It operates through rhythmic contractions controlled by intrinsic electrical impulses, regulated by the brain and hormones, illustrating the interconnectedness of the circulatory and nervous systems.

Based on the theory of evolution, if a population possesses a large amount of genetic variety, what level of variety can be expected in the future for that same population? A. The population will maintain the same level of genetic variety. B. The population will tend to become extinct. C. The population will increase in variety over time. D. The population will become more specialized in one particular direction.
Answer:
C. The population will increase in variety over time
Explanation:
If a population has a high level of genetic variety, that will result in even grater genetic variations as the times goes on. With the increase in genetic variation in the population, gradually new species will start to emerge from it, thus speciation will occur. This will happen because the greater genetic variations will enable some of the population to be able to use some other food sources over time, and if that is advantageous than those individuals will start to slowly move in other direction, thus becoming a separate species.

What are some non-specific responses of the immune system and how do they protect us from infection?
Answer: Some non specific responses in the body caused by the immune system are the release of body cells. (T-cells, T-killer cells, B-cells, B-Helper cells.)
Explanation:
When your body notices an intruding viruses or bacteria, it initiates a chemical response. (Aka your germacide.) You body has two systems that’s work together to kill these intruders, your non specific defense, and you specifics defense. Each has it’s own jobs. The non specifics job is to release you cells to the targeted area. When a cell is detected, and it gets into your blood your B cells will latch onto it and call your other cells to come kill it. Another way you’re non specific defense gets to work is your skin. You body always has germs on its skin, so it produces a anti germ liquid. Sometimes it doesn’t affect them, and sometimes it does. For the germs it attacks, it actually breaks down the cells cell. It’s like a acid for the germ.
