Q5.

The answer is A. In thermodynamics, the first law of conservation states that energy can never be destroyed or created but can only be transformed from one form to another. Therefore part of the electric energy was converted to light energy while the other dissipated as heat. However, the summation of the energy of these tow outputs in joules remains the same as initial electric energy.

The answer is B. This is because the water in the dam is used to turn turbines hence this form of energy is mechanical energy. As the turbines turn, they turn electromagnets that convert the mechanical energy into electrical energy

Rabies is a viral disease contracted from the bite of an infected animal. Rabies bypasses many immune system defenses by traveli

harina [27]

Answer:

D. Anterograde flow

Explanation:

Axonal transport is of 2 types:

Anterograde: Transport material from the soma towards the axon.
Retrograde: Transport materia from axon towards soma.

Pathology :

Virus enters tissue from saliva of biting animal.
Virus replicates in muscle near bite.
Virus moves to peripheral nervous system to CNS.
Virus ascends the spinal cord.
Virus reaches brain and causes fatal encephalitis.
Virus enters salivary glands and other glands and other organs of victim.

Hence,Rabies bypasses many immune system defenses by traveling in peripheral neurons to reach the CNS. While anterograde flow is NOT used by the rabies virus to reach the CNS

As food passes through the alimentary canal, the presence of chemical secretions will occur in which order?

mafiozo [28]

The alimentary canal includes mouth, esophagus, stomach, small intestine, and large intestine. As food passes through the alimentary canal, it is exposed to the different chemical secretions from the organs of the alimentary canal, as well as from other organs, such as liver and pancreas.
First, in the mouth, salivary glands produce saliva which contains enzymes involved in the food digestions. After the food is passed to the esophagus, it produces mucus to help passage of the food. In the stomach, acid and pepsinogen, as well as mucus are produced. All of these secretions help food digestion. Small intestine also produces some digestive enzymes. Further, bile from liver and enzymes from pancreas are secreted via ducts into small intestine. Finally, large intestine secretes mucus for lubrication.

Butoxors [25]

Answer: Studying botany helps companies develop more abundant food crops for less investment

Explanation:

The reasons for studying botany that is most directly related to increased profits was that "Studying botany helps companies develop more abundant food crops for less investment".

Since more food crops are gotten for less investment, it ultimately means that there'll be a reduction in the cost which will hence lead to an increase in revenue and therefore there'll be an increase in profit.
