The answer is C Heterozygous
Explanation: the inability to roll your tongue is a recessive trait. Since both parents are heterozygous, they carry that recessive gene, so their child will have a 25% chance of having that recessive trait; and therefore, unable to roll their tongue.
<span>Once the enzyme binds to the specific substrate molecule, structural changes can occur in the active site to accommodate the product. This structural change lowers the activations energy and increases the rate of the reaction. The active site changes its shape until an enzyme-substrate complex is formed and activated.</span>
Sensory neurons
Dmitry holds his hand close to a fire. His sensory neurons allow him to feel the heat, while his motor neurons allow him to move his hand away from the fire.
The Sensory neurons are the nerve cells that receive information from the sensory receptors and transmit the information from the sensory receptors to the brain through the spinal cord. In the question given, Dmitry was able to feel the heat when he held his hand close to the fire because the sensory receptors in the skin transmits information through the sensory neuron from the environment to the central nervous system.
Janine is right because CONSUMING TOO MUCH PROTEINS AND NO CARBOHYDRATES WITH PUT MORE PRESSURE ON THE LIVER AND KIDNEY. LIVER AND KIDNEY WILL REQUIRE MORE ENERGY TO BREAKDOWN TOO MUCH PROTEINS. THUS KIDNEY MIGHT GET RUINED DUE TO TOO MUCH WORK.
Carbohydrates, proteins and fats are used as source of energy and converted into energy. Carbohydrates are first to be metabolized for the production of energy. It is readily broken down into simple form. Brain uses only carbohydrate in the form of glucose as energy source. Glucose is used as an immediate fuel.
Protein is used as a source of energy when the body lacks carbohydrates. If protein and carbohydrates are received by the body in sufficient amount, protein is used for other specific purposes. Protein is not reserved for later use and our body do not store protein. It acts as building blocks of body to maintain the proper functioning of the body.
Fats are the last source of energy and used as energy source only in the absence of carbohydrates and proteins. Energy is stored in the body in the form of fat in the adipose tissues for later use in the absence carbohydrates and proteins. This stored fat is broken down into energy during exercise.
