Answer:

Energy

Explanation:

Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.

According to the research, the correct option is c, If fertilization occurs the egg burrows into endometium.

It is the tissue that covers or upholsters the uterine cavity whose function is to receive the fertilized egg when pregnancy occurs, that is, it allows the implantation of a fertilized egg, which will later transform into a new being.

For the endometrium to carry out its function, it has to undergo a series of morphological and functional modifications linked to the secretion of hormones by the ovaries so that at the time of greatest receptivity, the endometrium has the thickness and the nutrients necessary for a correct interaction with the embryo.

Therefore, we can conclude that according to the research, the correct option is c, If fertilization occurs the egg burrows into endometium.

Atom can be broken down into three constituents parts namely protons, neutron, and electrons.

Electron is a stable atomic particle that has a negative charge, the flow of electrons through a substance constitutes electricity.

Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net charge.

Sickle cell anemia results from a mutation in a gene called HBB, which contains the blueprint for cells to make part of a protein called hemoglobin. The hemoglobin protein is made up of two alpha chains and two beta chains.

Sickle cell anemia is the result of a point mutation, a change in just one nucleotide in the gene for hemoglobin. This mutation causes the hemoglobin in red blood cells to distort to a sickle shape when deoxygenated. The sickle-shaped blood cells clog in the capillaries, cutting off circulation.

B: The small intestine breaks down food into a thin mixture containing nutrients, while the large intestine absorbs water from the food mixture and turns it into solid waste.

Explanation:

Small intestine and large intestine are the important organs of digestive system in the human body. The small intestine functions by absorbing the nutrients of the simpler form of food. After absorbing the nutrients, the residue left is passed to the large intestine. The large intestine absorbs the water and further helps in eliminating the feces. It do not produces any enzyme to break the food unlike the small intestine. The process of digestion is completed by the small intestine.

The small intestine breaks down food into a thin mixture containing nutrients, while the large intestine absorbs water from the food mixture and turns it into solid waste.

The small intestine provides oxygen to the digested food before it goes to the rest of the body, while the large intestine absorbs nutrients and wastes from the food mixture.

The small intestine pumps food and nutrients throughout the body, while the large intestine turns the digested food into a thin liquid mixture.

Answer:

transpiration; evaporation

Explanation:

Definitions:

transpiration - the process of water movement through a plant and its evaporation
