Answer:

The correct answer is - option A. 0%

Explanation:

The zygote formation or fertilization in flowering plants occurs by the fusion of pollen of one plant with the ovum of another plant of the same species normally. This process includes the exchange of an equal amount of the genetic contribution from both plants.

The egg cell of the mother is responsible for the mitochondria and chloroplast of the progeny so the percentage of chloroplast genes provided via Plant R is 0% as ovum and egg cell comes from only plant Q.

percentage of chloroplast gene inherited from R plant is a)0%

If a population is steady at its carrying capacity, but then a group of organisms from that species moves in to the same space o
baherus [9]

Answer:

It will remain relatively stable

Explanation:

<u>The carrying capacity (k) of an environment is a factor that represents the maximum number of organisms of a particular species such environment can support based on the resources it has. </u>

<em>Below the carrying capacity</em>, the population of a species still has the potential to increase due to resource availability, and <em>above the carrying capacity</em>, the population has the potential to reduce due to the overstretching of the available resources. Factors that keep the population from expanding significantly beyond the carrying capacity include competition for resources, natural disasters, disease outbreaks, etc.

<em>Hence, if a population is steady at its carrying capacity and a group of organisms from that species moves into the same space occupied by the original population, the carrying capacity will only increase temporarily before factors such as competition and natural disasters operate to bring the carrying capacity to the normal level. </em>
