I believe the answer is C). My reason for this is because multipotency stands for multidifferentiative potential. And this is the ability to generate progeny of quite a few distinct cell types. And adult stem cells have that ability. Hope this helps.
The answer is; the skeletal system and the nervous system
The skeletal system (muscle and bone) give you rigidity and enable your legs to support your weight. The muscles also act on the bone as a fulcrum allowing it possible for them to contract and make motion possible.
The nervous system is important in the coordination of movement. The brain is the center for locomotor action. This ensures you are able to place one foot in front of the other in sequence and moving your arm in concert.
You forgot to put the options, but i believe it is magma.
TRUE. A true-breeding organism, sometimes also called a purebred, is an organism that always passes down certain phenotypic traits to its offspring.
Answer:
The correct answer is option b. "Guppy color patterns would change; guppies would produce fewer but larger offspring; the nitrogen excretion rate would increase and the rate of growth of primary producers such as algae would increase".
Explanation:
The Trinidadian guppy is a species of fish with the scientific name <em>Poecilia reticulata</em>. Just like almost all species, its population is regulated for multiple factors, one of them being the presence of predators. The removal of Trinidadian guppy predators would result in multiple consequences:
- Guppy color patterns would change. The fish have a complex coloration determined largely by predation avoidance.
- Guppies would produce fewer but larger offspring. This adaptation has been proved in an experiment at which the fish was introduced one a low predation environment. The report proved that evolution can take place in less than 10 years.
- The nitrogen excretion rate would increase. It has been reported that predation reduce Trinidadian guppy nitrogen excretion by 40%. Removing the predators will case the nitrogen excretion rate to increase due to an increase in the fish food intake.
- The rate of growth of primary producers such as algae would increase. This is an effect of the increase of nitrogen excretion rate, which benefits algae population to growth.
