Answer:
Scientist are worried about the future of some animals because their number and genetic diversity both is very low.
Genetic variation in the organism of the same species or different species provides the stability for the survival.
Even if the number of organism increases its stability will be low because the genetic variation of those organism is low.
So, even after their number increases they can die due to less variability so genetic variation is equally important as like that of population size.
Answer:
5. all of the above traits combined
Explanation:
Phylogeny has to do with the study of evolutionary relationships among living organisms based on the premise of the theory of organic evolution that states that all living organisms came from a common ancestor.
Phylogeny incorporates molecular, morphological, anatomical, biochemical and behavioural traits in order to arrive at a phylogenetic tree that represents ancestral lineages.
<em>Hence, the correct option is option 5. </em>
Answer:
Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding. Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. Sedimentary rocks are made when sand, mud and pebbles get laid down in layers. Over time, these layers are squashed under more and more layers. Eventually, the layers are lithified – turned to rock. Sedimentary rocks can be formed in deserts, lakes, rivers and seas .
