What is difference between respiration and photosynthesis?​

Thermostat

Explanation:

• The body tightly regulates the body temperature through a process called thermoregulation, in which the body can maintain its temperature within certain boundaries, even when the surrounding temperature is very different
• The core temperature of the body remains steady at around 36.5–37.5 °C (or 97.7–99.5 °F)
• The hypothalamus in the brain is the master switch that works as a thermostat to regulate the body’s core temperature
• The nervous system constantly relays information about the body's temperature to the thermostat, which in turn activates different physical responses designed to cool or warm the body, depending on the circumstances
• Responses may include: decreasing or increasing the flow of blood from the body's core, where it is warmed, to the surface, where it is cooled; slowing down or speeding up the rate at which the body turns food into energy (metabolic rate);inducing shivering, which generates heat through muscle contraction; and inducing sweating, which cools the body through evaporation
• A fever occurs when the thermostat resets at a higher temperature, primarily in response to an infection
• To reach the higher temperature, the body moves blood to the warmer interior, increases the metabolic rate, and induces shivering
• The chills that often accompany a fever are caused by the movement of blood to the body's core, leaving the surface and extremities cold; Once the higher temperature is achieved, the shivering and chills stop

Answer:

Carbohydrates - monosaccharides

Lipids - fatty acids, glycerol

Protein - amino acids

Nucleic acid - nucleotides

Answer: Carbohydrates: molecules composed of sugar monomers. They are necessary for energy storage. ...

Lipids: water-insoluble molecules that can be classified as fats , phospholipids, waxes, and steroids. ...

Proteins: biomolecules capable of forming complex structures. ...

Nucleic Acids: molecules consisting of nucleotide monomers linked together to form polynucleotide chains. ...

Explanation: I hope this helps.

Answer:

True.

Explanation:

Protein is a very versatile molecule and extremely important for the efficient functioning of the organism. However, proteins can only perform their functions through chains that wind and fold to form three-dimensional structures. these three-dimensional structures are the active form of the protein because they build the active site that will allow the substrate needed for body functions to fit and be catalyzed as needed.

In other words, the protein needs to be in its three-dimensional form for the construction of the active site to take place.

Answer:

The correct answer will be option-E.

Explanation:

Acetylcholine belongs to a group of chemical messengers which also acts as neurotransmitters in the synaptic transmission of the signals.

The acetylcholine is present in the vesicles in the synaptic knob which when released at the neuromuscular junction cause the contraction of the skeletal muscle along with cardiac and smooth muscle.

The mechanism of action is different in different muscles as the neurotransmitter binds to the nicotinic receptors present on the motor endplate and opens ligand-gated sodium channels.

In smooth and cardiac muscle it binds to the muscarinic receptors and cause the release of calcium ions and potassium ions respectively and cause muscle contraction.

Thus, option-E is the correct answer.

Answer:

The answer is by showing that cells contain a transforming factor.

Explanation:

Griffith, through his exploration could demonstrate that cells contain a changing material, which was later termed DNA. DNA is the reason for legacy in living life forms, accordingly he improved our comprehension of how kids acquire qualities from their folks.
