Answer:It is to ensure that a good percentage of offspring survive
Explanation: As with most organisms, there is a good chance that not all offspring will survive, due to factors such as limited resources, predation, etc. Thus certain measures have to be put into place by the parents to ensure a good chance at survival for their offspring. In this case, the eggs that are widely spread out are seen as sacrificial ones, because the parents will not be able to fully care for them and provide resources for them and the ones which were laid in the nest. They will also act as offerings for any predator on thee hunt. All of this will greatly increase the chance of survival for the eggs which were laid in the nest and will receive parental care .
Answer:
There is currently no consensus regarding the definition of life. One popular definition is that organisms are open systems that maintain homeostasis, are composed of cells, have a life cycle, undergo metabolism, can grow, adapt to their environment, respond to stimuli, reproduce and evolve.
Explanation:
Answer:
When soluble soil nutrients from the soil are washed away due to to effects of rain,floods or irrigation from agricultural practices the process by which this occurs is called LEACHING. As water molecules pass through different soil layers,soluble soil minerals are dissolved and carried by the water into the ground water.
Phosphorus is a soluble mineral which is easily carried away by the passing water molecules,and therefore drained from plants' roots.
if these were leached into rivers and drinking water,this may affect the water supply of the community as the percentage of Phosphorus increases in the water especially if NPK fertilisers were used.
In addition, some important solid nutrients are also leached into the underground soil layer leading to deficiencies in the plants.
Explanation:
Human stem cells haven’t specialized in to create an organ. This means that they can be manipulated to create a variety of organs for organ transplant and therefore lowers the risk of rejection
Somatotropin
Somatotropin is a polypeptide growth hormone that regulates the growth of bone, muscle, and other body tissues. Somatotropin is secreted by somatotropic cells within the anterior lobe of the pituitary gland. Somatotropin is important in human development as it stimulates growth, cell regenerations and reproduction in humans and other animals. The levels of somatotrophin rise increasingly during childhood and also occur at its peak in puberty.
