The correct answer is option 2- Study the lionfish in their natural habitat in the Pacific Ocean.
As mentioned in the question that lionfish is considered to be highly dangerous due to their fierce and veracious life style. In order to know more about the characteristics and impact of lionfish in order to develop potential solutions to the issue is to:
- Capture lionfish and study their spine in lab
- Study their life style in their natural habitat
This will help us to improvise ways that could help us protect other fishes from lionfish and also help us to develop a safe environment for the other marine animals.
Bones contain three components that in itself make it strong and flexible. They are collagen, calcium phosphate, and living bone cells. Collagen gives bones their structure, calcium makes bones strong, and cells generate more bone cells to fill up weakened parts. Calcium intake from food supplements and milk are also good for the bones because it can strengthen them more and make the skeletal system protected from bone irregularities and problems while growing. Vitamin D is essential for the absorption of calcium in bones. In order to offer support to the muscles and tissues of the body, bone growth is very crucial, because a weak bone cannot make the body function well. Comments Report
The correct answer is: Events that occur early in the fossil record are represented by branching events nearer to the root of a phylogenetic tree.
Fossil records explain the history and evolution of life based on fossils. Fossils are remains of organisms preserved in sedimentary rock. In fossil records they are analyzed and arranged chronologically and in taxonomic order, so that can represent the evolution.
Phylogenies describes the relationships between organisms (species): from which organisms it is evolved, to which species it is most closely related etc. and it is represented as a diagram or phylogenetic tree. It is used to organize living organisms into specific categories. Characteristics of fossils are used to generate a phylogenetic tree, more precisely their roots that represent common ancestors.
Answer: Certain traits increase in frequency in a population because when recombination occurs during sexual reproduction, genes are usually shuffled so that each parent gives its offspring a random assortment of its genetic variation, so the frequency of a gene may increase in a population through this genetic variation. One quote from a source I read states, "When recombination occurs during sexual reproduction, genes are usually shuffled so that each parent gives its offspring a random assortment of its genetic variation. However, genes that are close together on the same chromosome are often assorted together. Therefore, the frequency of a gene may increase in a population through genetic hitchhiking if its proximal genes confer a benefit."(lumen) This quotes explains why certain traits increase in frequency in a population.

Answer:
Intracellular transport is taking place with the help of microfilaments and microtubules. The plays the role of a highway for motor proteins such as dynein, kinesin, and myosin, which acts as the car of this highway that helps in transport.
Motor proteins help in changing the ATP to ADP by binding to it and attach or detach to the other parts of the cytoskeleton for transporting the vesicles as these proteins move.
Kinesin and dynein both are microtubule motor proteins. Kinesin transports full vesicles away from the nucleus, Dynein transports empty vesicles back towards the nucleus and myosin is a microfilament motor protein that transports both vesicles along microfilament.
