Answer: What stage of succession is taking place in the forest?
The first stage of forest succession is the grass, or plant stage, which occurs after land has been cleared due to natural events or otherwise. The sudden clearing floods the ground with sunlight; very shade-intolerant pioneer species like longleaf pine, aspen, or cottonwood begin to compete with grasses.
What three major processes contribute to succession?
Causes of succession
Three major causes have been identified for the process of succession. a. Initiating causes - These include biotic and climatic factors which destroy the existing populations of the area. Climatic factors include wind, fire, natural disasters, erosionWhat are the 4 stages of succession?
There are five main elements to ecological succession: primary succession, secondary succession, pioneer and niche species, climax communities and sub-climax communities.

Answer:
Telomeres cap and protect the ends of chromosomes from degradation and illegitimate recombination. ... Abolition of telomerase activity in such cells nevertheless results in telomere shortening, a process that eventually destabilizes the ends of chromosomes, leading to genomic instability and cell growth arrest or death.
Approximately 50% of the human genome
Answer:
Option A, 9:7
Explanation:
Given,
Genotype of A-B- have purple color
A-B- have genotype AABB, AaBb, AaBB, AABb
While genotype of A– bb, aa B–, and aa bb have white flowers
A– bb have genotype - AAbb, Aabb
aa B– have genotype aaBb, aaBB
Cross between Aa Bb and AaBb will give following offspring
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb AAbb aaBb aabb
So the possible genotypes and their corresponding phenotypes are
AABB-1 (Purple)
AABb-1 (Purple)
AaBB-3 (Purple)
AaBb -4 (Purple)
AAbb-2 (White)
Aabb-1 (White)
aaBB-1 (White)
aaBb-2 (White)
aabb-1 (White)
Purple : White = 9:7
