Answer:
Option B, temperature, water and soil nutrients
Explanation:
Abiotic factors are those which do not have life in them and are unable to exhibit the functions of a living organism such as locomotion, reproduction, feeding, respiration etc.
All the set of factors in option B i.e temperature, water and soil nutrients are not living things as they do have any of the characteristics of living beings and thus they can be considered as abiotic factors.
While in all other options except option B, i.e option A, C, and D factors like animal, grass and animal life are biotic factors as they have life and are able to perform functions of living beings.
Thus, abiotic factors associated with ecosystems are temperature, water and soil nutrients
Answer:
-if I'm not wrong the technique is used to produce the bacteria cell is DNA cloning because after a ligation, the next step is to transfer the DNA into bacteria in a process called transformation.
-The organic compounds scientist used to cut DNA is enzymes.
-the possible result would be the transformations made and selection of the bacteria.
Answer:
Cellulose
Explanation:
Cell walls made of cellulose are only found around plant cells and a few other organisms. Cellulose is a specialized sugar that is classified as a structural carbohydrate and not used for energy. ... While cell walls protect the cells, they also allow plants to grow to great heights. You have a skeleton to hold you up.
Answer:
They cannot use the reasoning, "Dolphins and Ichthyosaurs form a paraphyletic group."
Explanation:
This is because they always form a monophyletic goup. Both of the species have specific morphological similarities that are enough to consider them in monophyletic group instead of a divergent paraphyletic.
Three ways scientists base their identifications of evolutionary relationships are:
1. Does not take genetics into account.
2. Does not consider convergent evolution.
3. Physical similarities does not mean that they are related.
Evlutionary relationships talks about relatedness between organisms, usually this can be shown by a phylogenetic tree through phylogeny. Reconnection and speciation of organisms must be considered in studying relatedness of organisms.
