Answer: One of the biggest questions is, Can we replicate these results in other plants? So, there needs to be more research to determine whether this technique is effective in food crops. It’s not known what the protein PsbS does, even though it seemed to enhance plant growth. There should definitely be more research to find out how this protein is linked to plant growth and whether boosting this protein will affect growth in other types of plants. The researchers also noted that there are numerous other ways to make photosynthesis, and there are more than 100 chemical reactions involved in the process. Investigating other possibilities might be the key to improving crop yield in a wide variety of crops.
Explanation: same answer from edmentum.
Answer:
Mutation plays an important role in evolution. The ultimate source of all genetic variation is mutation. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele.
Answer:
Population size of elk increased while the population of aspen tree declined.
Explanation:
As per question, removal of wolves from the system would result in increased elk population due to absence of its predator (wolves). The increased elk population would extensively feed on shrubs and trees like aspen and cottonwood trees. This would cause decline in population size of these shrubs and trees.
The process of classifying an organism into a clade by comparing similarities in body symmetry and other morphological traits comprises - 1. body plan-based cladistics cladistics based on body plan, morphology-based phylogeny.
<h3>What is cladistics based on body plan ?</h3>
A method of biological taxonomy that organizes taxa in a branching hierarchy so that all members of a given taxon share the same ancestors and defines taxa uniquely by shared traits not present in ancestral groupings.
- Cladistics is a method of biological classification in which groups of species (or "clades") are assigned based on theories of most recent shared ancestry.
- The evolutionary link between recent ancestors and descendants, or the course of evolution, is shown via cladistics. An aid to representing it is a cladogram. Since clades serve as the foundation for phylogenetic trees, cladistics is a component of the phylogeny.
<h3>What is molecular-based phylogeny ?</h3>
Molecule structure is used in molecular phylogeny to shed light on an organism's evolutionary connections.
- A so-called phylogenetic tree represents the findings of a molecular phylogenetic research. DNA, RNA, and proteins are components of all living things.
- Molecular phylogenetics creates a phylogenetic tree by drawing conclusions about the evolutionary links that derive from molecular evolution.
<h3>What is Morphology-based phylogeny ?</h3>
Using anatomical features, morphological phylogenetics infers evolutionary trees. Node: A branching point when an ancestral lineage splits into two (or more) daughter lineages in an evolutionary tree.
The ability to discuss the phylogeny of fossil taxa and how they relate to modern taxa is the unquestionable benefit of morphological data. However, their strategy prevents us from addressing the situation of extinct taxa for which there is no way to gather DNA data (i.e., almost all of them).
