Answer:
DNA is nucleic acid
Explanation
Answer:
The main difference between plant cell and animal cell cytokinesis is the formation of new cell wall surrounding the daughter cells. Plant cells form a cell plate between the two daughter cells. In animal cells, a cleavage furrow is formed between the two daughter cells.

Fahrenholz's rule is supported when: comparison of phylogenies for host and parasite show a correlated pattern of evolution
<h3>What is Fahrenholz's rule ?</h3>
The close correspondence is observed between the taxonomy of parasites and their hosts and this has led to Fahrenholz's rule. This rule postulates that parasites and the hosts speciate in synchrony.
This leads to a prediction that phylogenetic trees of parasites and their hosts are topologically identical.
when the only events in the process of reciprocal natural selection in the host and parasite lineages were those of contemporaneous speciation in both the lineages then host and parasite phylogenies are fully congruent, hence supporting Fahrenholz'srule.

Answer:
1. Natural
2. Natural
3. Natural
4. Manipulative
5. Manipulative
6. Manipulative
7. Natural
Explanation:
In a natural experiment, the researcher can specify that any proposed health implications could be due to exposure to the toxic chemical, but proving its direct causation is difficult. Natural experiments are majorly fixed to promoting correlation, unlike the manipulative experiments which usually strongly reveals causation.
Manipulative experiments changes the amounts of a predictor factor and estimates how one or more variables acts to these changes. It is employed in a test cause-and-effect. It cannot be used for large experimental scales as they are for small spatial scales experiments.
Natural experiments makes use of an observational study on natural variation in the variable of interest. It is used for large spatial and temporal scales without the need for manipulations but cannot be used for the direction of cause-and-effect.
Answer: produce energy; photosynthesize
Explanation:
Mitochondria and Chloroplast are similar because both are cellular organelles involved in ENERGY PRODUCTION:
- Chloroplasts in green plants, due to its membrane containing chlorophyll molecules produces energy during photosynthesis
- Mitochondria in animal cells produces energy in form of ATP during lipid oxidation occuring in its membrane.
However, both organelles DIFFER in that ONLY CHLOROPLAST allows photosynthesis in its membrane, unlike Mitochondria
