It is not possible for two species with the same niche to coexist. one species will eventually drive the other into extinction
Some fruits—for example, the dandelion—have hairy, weightless structures that are suited to dispersal by wind. Seeds dispersed by water are contained in light and buoyant fruit, giving them the ability to float. Coconuts are well known for their ability to float on water to reach land where they can germinate.
A mating between a purebred purple-flowered pea plant and a purebred white-flowered pea plant would produce a Hybrid.
In human genetics, assortative mating is a type of nonrandom mating in which pair connections are created based on phenotype (observable characteristics).
A statistical link between genotype and phenotype predicts a physical characteristic in a person or an anomaly in a patient with a specific mutation or a collection of mutations that are related to it.
The genotype of a purebred purple flowered pea plant will be PP
while the genotype of purebred white-flowered pea plant will be pp.
on crossing
PP X pp
Pp, Pp, Pp, Pp (offspring)
hence all the offspring produced will be hybrids.

#SPJ4
Answer:
The original number is -4.
Explanation:
Let the original number be n.
Next, three times the number is equal to 3n.
Then, increased by 4 means 4 is added.
Hence, three times a number increased by 4 equals -8 is written in the equation form as shown below.
=> 3n + 4 = -8
=> 3n = -8 + (-4)
Since the number, 4, goes on the other side of the equal sign, the number positive 4 changes its sign and becomes negative 4, as shown above.
=> 3n = -8 -4
=> 3n = -12
=> n = -12/3
=> n = -4
Checking the above solution.
Three times the number is equal to 3 * (-4) = -12.
The above product when increased by 4 gives the equation as shown.
-12 + 4 = -8.
The result is -8.
This result is same as the result mentioned in the given question, -8.
Hence, the answer that -4 is the original number is correct.
