people infected with hiv, the virus that causes the disease aids, can become unable to fight off infections by organisms that normally do not harm people. why is this so?
People infected with HIV, the virus that causes the disease AIDS, can become unable to fight off infections by organisms that normally do not harm people because: HIV weakens the immune system.
The virus does this by attacking and destroying CD4 cells (also known as T-cells), which are a type of white blood cell that is essential for defending the body against infections.
HIV invades CD4 cells and copies itself, which causes the cell to die. This process causes the body to lose CD4 cells, and without them, it is unable to fight off infections by other organisms. Without treatment, HIV can also spread to other organs and tissues in the body, causing further damage to the immune system.
Ultimately, this makes it difficult for people infected with HIV to fight off infections by organisms that usually do not cause any harm.

if individuals lack the enzyme that converts phosphoenolpyruvate to pyruvate, what would you expect to happen to the concentration of 2-phosphoglycerate as an immediate consequence?
When individuals lack the enzyme that converts phosphoenolpyruvate to pyruvate, the concentration of 2-phosphoglycerate would increase as an immediate consequence.
Pyruvate is created from the glycolytic breakdown of glucose. Pyruvate is converted to acetyl-CoA in the presence of oxygen, which is then oxidized in the Krebs cycle to generate ATP.2-Phosphoglycerate is a molecule that is involved in glycolysis, a metabolic process that converts glucose into pyruvate. 2-Phosphoglycerate is generated by the reaction between phosphoenolpyruvate and ADP. The conversion of phosphoenolpyruvate to pyruvate is catalyzed by the enzyme pyruvate kinase. This is the last step in glycolysis, and it generates ATP from ADP. I
f individuals lack this enzyme, the concentration of phosphoenolpyruvate will increase while the concentration of pyruvate will decrease. In such a situation, the concentration of 2-phosphoglycerate would increase as an immediate consequence.

one way carbon moves from the atmosphere to the biosphere is through a process by which plants use light energy and convert it into biochemical energy. what is this process called?(1 point)
The process by which plants use light energy and convert it into biochemical energy is called photosynthesis. One way carbon moves from the atmosphere to the biosphere is through photosynthesis.
What is photosynthesis?Photosynthesis is a biological process in which green plants, algae, and some bacteria use sunlight, water, and carbon dioxide to produce oxygen and carbohydrates. Oxygen is generated during the photosynthetic process as a by-product, which is released into the environment. The carbohydrates produced by photosynthesis provide energy for the plants, and are stored in the plant's cells.
Glucose is a simple sugar that is produced during the process of photosynthesis. The sun is the primary source of energy for photosynthesis. Chlorophyll, a green pigment found in the chloroplasts of plant cells, absorbs light energy from the sun. Chloroplasts are specialized structures in plant cells where photosynthesis occurs. Carbon dioxide is absorbed from the air through small pores in the plant's leaves called stomata, and water is absorbed through the roots of the plant.
During photosynthesis, the absorbed light energy is used to convert carbon dioxide and water into glucose and oxygen. The equation for photosynthesis can be written as:6CO2 + 6H2O + energy → C6H12O6 + 6O2Photosynthesis is essential to life on Earth because it produces oxygen, which is necessary for the survival of most organisms. It is also the primary source of food for many organisms, as the carbohydrates produced by photosynthesis provide energy for growth and reproduction.

why were the authors concerned about temperature effects of sunlight on leaves? what solution did they find to deal with their concern? (3 points)
The authors were concerned about the temperature effects of sunlight on leaves because they can cause photoinhibition and heat stress in plants and the solution the authors found was to use shade clothes to deal with their concern.
Photoinhibition is a decrease in photosynthetic efficiency due to excessive light, while heat stress occurs when the temperature of the leaf exceeds the optimal temperature for photosynthesis.
The authors used shade clothes to reduce the amount of sunlight reaching the leaves. This is because the clothes provide an additional layer of insulation between the sun and the leaves, and the clothes also reflect some of the sunlight away from the leaves.
The authors also found that providing additional ventilation to the plants helped reduce temperatures, as this allowed for more air circulation around the leaves.

a muscle spindle is a tonic proprioceptor. what happens to the signal on the sensory afferent neurons that come from the spindle when the muscle spindle is stretched?
When the spindle is stretched, it sends a signal through the sensory afferent neurons, which causes the muscle to contract. This contraction is an unconscious reflex known as the stretch reflex.
A muscle spindle is a tonic proprioceptor found in muscles that detects and measures changes in muscle length.
The stretch reflex occurs when a muscle is stretched, and the sensory afferent neurons send a signal to the alpha motor neurons. This signal causes the alpha motor neurons to initiate a contraction of the same muscle, resulting in a reflexive contraction of the muscle.
The signal sent from the sensory afferent neurons is an action potential, which is an electrical impulse generated by the sensory afferent neuron. This impulse travels to the alpha motor neuron which causes it to send an action potential to the muscle fibers, resulting in a contraction of the muscle.
The magnitude of the reflexive contraction of the muscle is dependent on the intensity of the stimulus received from the sensory afferent neurons. If the stimulus is too intense, the reflexive contraction will be too strong and may even cause a spasm in the muscle.
In conclusion, when the muscle spindle is stretched, the signal sent through the sensory afferent neurons causes a reflexive contraction of the same muscle, resulting in an unconscious response. The magnitude of the reflexive contraction is dependent on the intensity of the stimulus received from the sensory afferent neurons.

Answer: chemical change
Explanation:
gastric accommodation is an example of smooth muscle plasticity. gastric accommodation is an example of smooth muscle plasticity. true false
The given statement is True. Gastric accommodation is an example of smooth muscle plasticity.
Smooth muscle cells differ from striated muscle cells because of their structure and function. Smooth muscle cells are elongated and spindle-shaped, with a single, centrally located nucleus. They're not divided into segments, unlike striated muscles. Smooth muscles, unlike striated muscles, are controlled by the involuntary nervous system. They're found in the body's walls of organs, like the intestines, bladder, and blood vessels. They may contract and relax without the need for input from the brain or spinal cord.
The adaptation of smooth muscles to changes in the physiological environment is known as smooth muscle plasticity. It's a type of tissue plasticity that allows smooth muscles to adapt to the altering mechanical properties of their microenvironment. When the gastric smooth muscle adapts to the stomach's food content, it's referred to as gastric accommodation.
Gastric accommodation refers to the capacity of the stomach to stretch and expand to accommodate the meal's volume. Gastric accommodation is a result of the stretching and expansion of the stomach's smooth muscle cells. The walls of the stomach's smooth muscle cells become less stiff, allowing the stomach to expand and accommodate a greater volume of food.
Thus, gastric adaptation is an example of smooth muscle plasticity, as it allows the stomach to adjust to the volume of food entering it.
