While plants can produce their own energy using the process of photosynthesis, animals (and other organisms that can’t do photosynthesis) must eat to get energy from food molecules. Just like energy can be stored in the chemical bond between the second and third phosphate of an ATP molecule, energy can also be stored in the chemical bonds that make up food molecules. Most of the energy that we use comes from molecules of glucose, a simple sugar.
Answer:
Attractive forces between particles.
Explanation:
Solids keep its shape and volume because of strong attractive forces between the particles.
Other options are incorrect:
Because there is no space between solid particles.
The shape of solid does not depend upon type of particles present.
The shape and volume of solids not depend upon the volume and shape of container.
Properties of solids:
Solids have definite volume and shape.
In solids molecules are tightly pack and very close to each other.
Their melting and boiling point are every high.
The densities of solids are also very high as compared to the liquid and gas.
There are very strong inter molecular forces are present between solid molecules.
Answer:
In lions, digestion takes place in the stomach while in elephant, digestion takes place in cecum.
Explanation:
Lion eats meat which needs a powerful digestion of strong juices which helps in the breakdown of food. There are four compartments of the stomach of lion that are rumen, reticulum, omasum, and abomasum. These chambers have microorganisms which helps in the breakdown of food materials while in the elephant, the stomach primarily functions in the storage of food and digestion takes place in the cecum that is connected to the large intestine.
The correct answer is active hyperemia.
Active hyperemia represents the increase in organ blood flow (hyperemia) that is associated with the increased metabolic activity of that organ. In this case, the increase in blood flow accompanies muscle contraction during the exercise. Muscle contraction stimulates the production of vasoactive (vasodilative) substances that dilate the vessels and thus, bring more oxygen to the muscles.
Answer:
Density Independent
Explanation:
Density independent is the factor that will affect a population no matter its size. Temperature, natural disasters, and oxygen levels all influence this.
