An example of a population in which evolution could take place in a relatively short period of time could be pathogenic bacteria exposed to antibiotics.

Answer: Option A

Explanation:

Evolution if takes place within a short period of time say the next generation that is called as micro evolution. This is caused when a specific organism exposed in a different environment at once modifies its genes to suit the new environment. This phenomenon can be very well seen in the pathogenic bacteria which are exposed to antibiotics.

When an antibiotic is prescribed to bacteria initially it nullifies its effect by destroying it. When continuously exposed to a certain antibiotic some bacteria dies but there are few which becomes resistant to it and survives. This on the other hand multiplies producing a generation that can’t be touched by the antibiotic.

Solnce55 [7]

The right answer is: D. the formation of clouds

Condensation is the second stage of the water cycle. The water vapor circulating in the atmosphere will encounter a colder air and it will turn into droplets, this phenomenon is called condensation.
Water droplets accumulate in the form of clouds of different shapes, density, and altitude. This phenomenon is called condensation. Water vapor travels on the surface of the earth in the form of clouds.

Using sophisticated molecular cloning techniques, you have isolated the genes for two serotonin transporters, called TransA and

kherson [118]

Answer:

Vesicles

Explanation:

Serotonin is a neurotransmitter that transports signals or messages between neurons.

Most neuronal cells have vesicles in their interior, which are organelles that store neurotransmitters for exportation -by exocytosis- or from recycling -by endocytosis-. These vesicles also protect the neurotransmitter from the enzymatic action.

Vesicles form in the cellular soma, from where they are transported to nervous terminals. Once the vesicle releases the neurotransmitter to the intercellular space, their membrane remains available in the plasmatic membrane to be reused.

The neurotransmitter concentration in the vesicle interior is related to the storage system and the transport system. There are specialized transporter proteins in the vesicle membrane that are involved with the introduction of the molecule to the organelle.

In the exposed example, transporter Trans B might be located in the vesicle membranes, and hence could be found in the cytosol of the cells.
