Answer:

Polyploidy

Explanation:

Polyploidy can be defined as a rapid method of speciation that has been important in the history of flowering plants.

In plants, it involves the possession of two complete sets of chromosomes and it leads to the origin of new species.

Hence, the two sets of chromosomes comprises of triploidy (69 chromosomes) and tetraploidy (92 chromosomes).

Answer:

behavioral isolation

Explanation:

Speciation  can be explained as a situation when a group within a species separates from other members of its species and develops its own unique characteristics. It can also be described as an evolutionary process by which populations evolve to become distinct species. This means that , through this process a new kind of plant or animal species is created.

The things that were known to be cause of speciation are rivers change course, mountains rise, continents drift and organisms migration.

Behavioral isolation can be described as a barrier that prevents interbreeding between closely related species because there is no mate recognition between females and males of the different species. This means the development of different behaviors that are not recognized or preferred by members in another population.

In this case, behavioral isolation has been the major driver of speciation in flowering plants ,and has been the mechanism that ensure the production of viable offspring.

2.the ingestion of bacteria or other material by phagocytes and amoeboid protozoans (wasn’t sure for this one so I had to research)
3.amoeba takes in nutrition by the process called phagocytosis.in this process,a solid food particle is first surrounded by pseudopodia (cytoplasmic filled projection of cell membrane) and forms a vacuole called as Phagosome

Is the vagus nerve the heart rate centre of the brain?
koban [17]

Answer:

The vagus nerve has two bunches of sensory nerve cell bodies, and it connects the brain stem to the body. It allows the brain to monitor and receive information about several of the body’s different functions.

Explanation:

The vagus nerve is the longest and most complex of the 12 pairs of cranial nerves that emanate from the brain. It transmits information to or from the surface of the brain to tissues and organs elsewhere in the body.

There are multiple nervous system functions provided by the vagus nerve and its related parts. The vagus nerve functions contribute to the autonomic nervous system, which consists of the parasympathetic and sympathetic parts

The vagus nerve has a number of different functions. The four key functions of the vagus nerve are:

-Sensory: From the throat, heart, lungs, and abdomen.

-Special sensory: Provides taste sensation behind the tongue.

-Motor: Provides movement functions for the muscles in the neck responsible for swallowing and speech.

-Parasympathetic: Responsible for the digestive tract, respiration, and heart rate functioning.
