Answer:
Dragonflies are important for our environment.
Explanation:
Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.
Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water.

Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.
Answer:

Explanation:
The symbiotic relationship between Remoras and sharks is a commensalism relationship where the the shark neither benefit nor loss from such relationship

The host organism neither benefit nor get harmed
From the question, Remoras are the commensal organism while sharks are the host organism
It is unsafe because it could give the baby defects.
Answer:
a.) rate of population growth
Explanation:
The population growth rate determines how a population will be distributed in a region. Populations with a high growth rate need to occupy more spaces, in addition to needing to consume a greater volume of natural resources. As the population grows, the distribution in the region becomes more intense, the opposite also happens. When the population growth rate indicates that the population is decreasing it means that this population will need less space and therefore, its geographic distribution will be smaller, as well as its impact on the region.
