Answer:
Coral reefs are under threat if atmospheric carbon dioxide levels continue to rise, new research has shown. When CO2 dissolves in the ocean, it raises the water's acidity level. This prevents a build up of calcium carbonate, which corals draw from seawater to build their skeleton
Explanation:
Answer: poaching and habitat loss
Explanation: succession and extinction quiz
1. 
where in a population:
p - the frequency of the <em>A</em> allele
q - the frequency of the <em>a</em> allele
- the frequency of the <em>AA</em> homozygous genotype
- the frequency of the <em>aa</em> homozygous genotype
2pq - the frequency of the <em>Aa</em> heterozygous genotype
A population at equilibrium will have the sum of all the alleles at the locus equal to 1.
2. Conditions:
A. The breeding population must be large
B. No natural selection
C. The mating must occur randomly
D. No mutations to cause changes in allelic frequency.
E. No changes in allelic frequency due to immigration or emigration.
3. By comparing the actual genetic structure of a population with what we would expect from a Hardy-Weinberg equilibrium, we can determine how much it deviates from the baseline provided by the mathematical model. Depending on how large the deviation is, one or more of the model's assumptions are being violated. Thus, we can attempt to determine which one.
Answer:
They share common ancestors
Explanation:
DNA remain conserve for long time and genetic code dna us major source to know that if irganistims share common ancestors
Biodiversity supports biological system efficiency where every specie, regardless of how little, all have a vital part to play. For instance, A bigger number of plant species implies a more prominent assortment of products. More noteworthy species assorted variety guarantees common maintainability for all living things.
