Osteoclasts are responsible for aged bone resorption and osteoblasts are responsible for new bone formation. cytokinin involved in bone remodeling.
In order to maintain appropriate skeletal structure and function, bone must undergo continuous remodelling. So, diseases like osteoporosis may result from unbalance. Bone remodelling is a complex process involving numerous cell types and elements. These processes primarily involve the two cells known as osteoblast and osteoclast. For the resorption of old bone and the production of new bone, respectively, osteoclasts and osteoblasts are responsible. Under physiological circumstances, the resorption and formation are steady. The structure or function of the bones will be aberrant if the balance is off, though. Osteoporosis and osteopetrosis are diseases of the bone metabolism that can occur.

Why don t these enzymes digest the stomach and small intestine which are partially composed of protein?.
Enzymes have a difficult time working on the live protein chains that line your mouth, stomach, and intestine. Because the live protein chains are tightly coiled, enzymes cannot come into contact with them.
Enzymes are proteins that act as catalysts, increasing the rate of chemical reactions without changing the overall process.
The stomach, pancreas, and small intestine produce protease. The majority of chemical reactions take place in the stomach and small intestine. Pepsin is the primary digestive enzyme that attacks proteins in the stomach.
Pepsin is released in an inactive form, or zymogen form, by specific cells within the gastric lining known as chief cells. In this way, the stomach prevents the auto-digestion of protective proteins in the digestive tract lining.

what is the primary function of the pyloric valve?
Answer: The primary function of pyloric valve is to pass the food from stomach to the top of small intestine
Explanation: The pyloric sphincter at the bottom of the stomach is a muscular valve which helps to transfer food from stomach to small intestine.
Stomach is a muscular sac about the size of a small melon . once the stomach breaks the complex and strong muscular contractions , food is pushed towards the pyloric valve . This valve leads to the upper portion of your small intestine, a segment known as the duodenum.
What color of light would be least effective for plant photosynthesis?.
Green light's wavelength is thought to be the least efficient for photosynthesis. The rate of photosynthesis will be the slowest if the plants are exposed to green wavelengths during photosynthesis. This is because chlorophyll, a green pigment, is present.
Although different species perform photosynthesis in different ways, the process always starts with light energy being absorbed by proteins called reaction centers, which contain green chlorophyll (and other colored) pigments/chromophores. These proteins are held inside chloroplasts, which are most abundant in leaf cells in plants, whereas they are embedded in the plasma membrane in bacteria. Some energy is used in these light-dependent reactions to strip electrons from suitable substances such as water, resulting in the production of oxygen gas.

The oxygen-carrying protein hemoglobin in red blood cells becomes dysfunctional as a result. In certain cases, this results in a hard, sickle-like form. Sickle cell disease problems often start at the age of 5 to 6 months. Anemia, swelling in the hands and feet, bacterial infections, stroke, and pain episodes (also known as sickle cell crises) are just a few of the health issues that could arise.

In a medical setting, the amount of substances in blood can be a key indicator to health or disease.
An average human has approximately 5L of blood. Inside this 5L are the cellular component and a liquid portion made
mostly of water, called plasma. The cellular component contains the red and white blood cells, as well as platelets that aid
in blood clotting. The remainder of the blood is plasma, containing all other dissolved nutrients such as glucose, ions and
proteins.
A centrifuge can be used to separate the cellular components from the plasma. The red blood cells would travel to the
bottom of the centrifuge tube and make up almost 45% of the blood. A measure of the percentage volume of whole blood
that is made up of red blood cells is called the haematocrit. The platelets (0.17%) and white cells (0.1%) would form a very
thin layer called the buffy coat and sit just on top of the red cells. The plasma would be at the top and would be about 55%

Answer:
A number of factors can influence the respiration rate, such as:
Age – younger children generally have higher oxygen demands and therefore breath faster
Pain – pain will cause an increase in respiration rate
Emotion – emotion will cause an increase in respiration rate
Resistance from air passages – increased resistance (e.g. in asthma) prevents as much air entering the lungs during each cycle. The demand for oxygen will then increase, increasing the respiration rate.
Fever – fever increases the body’s demand for oxygen, increasing the respiration rate
Elasticity of the lungs – the less elastic the lungs, the less air can enter the lungs each cycle, increasing the respiration rate.
Chemical changes – chemical changes in the body, caused by hypoxia, metabolic disorders or medications / drugs, can cause the respiration rate to increase or decrease, depending on the stimulus
