Answer:
Polar Bears feed on seals. So, polar bears and seals share a prey predator relationship. If one species cannot then adapt an appropriate defense, they may go extinct. In this way, the predator prey relationship often forms and "evolutionary arms race", in which eats species rapidly evolves to counter the other.
Explanation:
Complete the paragraph based on this food web: Polar bears feed on seals. So, polar bears and seals share a _prey predator_.Climate change has caused ice caps to melt in colder regions where polar bears live. This change has caused them to hunt less. This situation will lead to_?extinction?_ 1 prey-predator relationship mutual relationship parasitic relationship. 2 less biomass in the quaternary level increased biomass in the quaternary level less biomass in the primary level.
If one species cannot then adapt an appropriate defense, they may go extinct. In this way, the predator prey relationship often forms and "evolutionary arms race", in which eats species rapidly evolves to counter the other.
Answer:
Describes ecosystem homeostasis
Explanation:
It totally depends upon whether modification is being done in somatic cells or germ cells. Somatic cells modification is ethically accepted because it doesn't pass from one generation to another generation but germline modification is considered as unethical because the modification will pass on to the next generation leading to the persistence of modification in future generations. The problem with genetic modifications is that the impacts of modifications are unpredictable, rather than being fruitful they may lead to lethal mutations so if it occurs in just somatic cells, then even if it is lethal/harmful, it will be confined to only that individual but if a lethal mutation occurs in germ cells then it will pass on to the subsequent generations and it will persist in all future generations.
Answer:
The answer is A. Heterozygous
The pit that marks the location of the umbilical cord after birth is known as the navel or belly button. All animals that grow placenta during fetal development will have a navel or belly button. The scientific name of the structure is the umbillicus. It can be a depression in some individuals or raised in others.
