Proteins
Proteins is the most thermogenic of all nutrients and macromolecules we eat. Thermogenesis is the generation of due to digestion and metabolism of food. Studies shows that proteins tend to be more thermogenic that carbohydrates and fats. This means that the calorie given of by proteins is converted and released as heat and less available for storage. This means that the stored energy formed from protein much of it is released as heat and unlike other macromolecules few of it is converted to a energy that can be stored.
Enzymes.
because enzymes are a substance produced by a living organism that acts as a catalyst to bring about specific biochemical reaction.
Answer: Option E (B and D are the only examples.
Mediterranean ecosystem with hot dry summer and fire can be found on various continents across the globe. Plants in these ecosystem have evolve similar adaptations to survive these circumstances.
Echidnas are egg laying mammals that live in Australia and new Guinea. They are sometimes known as spiny anteaters since they are covered in spines and mostly eat ants and termites. As such they resemble south American anteaters and hedgehogs but are not closely related to them. Instead echidnas descended from an aquatic platypus like ancestor.
Explanation:
Divergent evolution is a process where different organisms with different anscetors evolve independently and develop similar traits due to their adaptation to similar environment.
Another example is the similarities between hummingbird and hummingbird moth, the evolved from different ancestors and yet posses similar characteristics.
Answer:
Answer is option B - "I should shower rather than take a tub bath."
Explanation:
Abdominal hysterectomy is the surgical removal of a part or all of the uterus by making an incision in the lower abdomen. After the surgery, the patient normally spends 2 - 5 days in the hospital and takes at least 4 - 6 weeks to get completely better. Some of the major discharge instructions are;
- Drink enough water and eat smaller meals that are rich in proteins and fiber and plenty of fruits and vegetables daily. This helps with the healing process and prevents constipation.
- Avoid swimming or taking a tub bath, but can take showers.
- Dressings over the incision should be removed daily and keep the wound area clean.
- Avoid inserting anything such as tampons into the vagina for 6 weeks after the surgery.
- Avoid all heavy activity including strenuous household activities, weightlifting, and other strenuous exercises. Short walking and light household chores can be done.
- Avoid driving if the patient is taking narcotic pain-relieving medicines. Long trips in vehicles or airplanes are not recommended for 4 weeks after the surgery.
Answer:
B) The mass of the reactants equals the mass of the products,
Explanation:
Given that the reaction is balanced, the mass of the reactants must equal to the mass of the products.
We know this by virtue of the law of conservation of mass.
The law of conservation of mass states that "in a chemical reaction, matter is neither created nor destroyed but atoms are rearranged".
Therefore, if the reaction is chemically balanced, the mass of reactants must be the same as the mass of the products in the reaction.
The second choice is the right one.
