Briefly explain why cutting a flatworm into pieces would not kill it

Biology
1 answer:
gladu [14]3 years ago
3 0

Cleaving a flatworm into pieces would not kill the flatworm as each piece would turn into a new flatworm. The mechanism is known as fragmentation. In multicellular species, fragmentation refers to a kind of asexual reproduction in which a species gets cleaved into fragments.  

Each of these fragments forms into completely developed, mature individuals, which are similar to their parents. Fragmentation is also called splitting, it is a mode of reproduction witnessed in various species like molds, filamentous cyanobacteria, lichens, various plants, and animals like flatworms, sponges, sea stars, and some annelids.

Cardiac output is the amount of blood pumped by the heart in one minute. Which of these will increase cardiac output?
uranmaximum [27]

Answer: the factors that increase cardiac output include:

--> Nervous stimulation and

--> Hypertrophy of the heart.

Explanation:

Cardiac output can be defined as the quantity of blood pumped into the aorta each minute by the heart. This is also the quantity of blood that flows through the circulation. There are factors that can cause increased cardiac output or that can lead to a hypereffective heart. They are:

--> NERVOUS STIMULATION: The combination of sympathetic stimulation and parasympathetic inhibition does two things to increase the pumping effectiveness or cardiac output of the heart. These include:

• it greatly increase the heart rate from the normal level of 72 beats/mum up to 180 to 200 beats /mom.

• it increases the strength of heart contraction, which is called increased contractility to twice it's normal strength.

--> HYPERTROPHY OF THE HEART: A long term increased workload, but not so much excess load that it damages the heart, causes the heart muscle to increase in mass and contractile strength in the same way that heavy exercise causes skeletal muscles to hypertrophy. This effect of increased muscle mass of the heart, allows the heart to pump much greater than usual amounts of cardiac output.
