The answer is All of the above
It is believed that the tilapia fish was introduced into the mangrove system by escaping from fisheries and aquariums by accident, but this species is also used to control the population of mosquitos to prevent outbreaks of malaria and other invasive species on which they feed.
The tilapia are highly tolerant and easily adaptable to different conditions in the mangrove ecosystem and they are highly efficient predators. This often makes them more successful in the environments where they are introduced than the indigenous species, which results in disruption of the food chain.
The negative human impact on mangroves disrupts the balance in the mangrove ecosystems, weakening the populations of different species that originate from mangrove forests. This leaves more space and resources to be exploited by the tilapia.
The strategies to control tilapia in mangrove ecosystems focus on restoring the habitat and strengthening the populations of indigenous species while decreasing the numbers of tilapia.
The species can be eradicated by selective overfishing of the species or by introducing another species into the habitat which is a natural enemy of the tilapia.
Answer:
C. Meiosis produces new combinations of chromosomes.
Explanation:
Compared to mitosis, meiosis divides TWICE and has EIGHT stages of rather than mitosis with the regular four stages.
The end result in Meiosis produces haploid cells in which half of the amount of chromosomes are produced in each individual cell, therefore Meiosis produces new combinations of chromosomes.
A. is incorrect because Meiosis does NOT create genetically identical cells.
B. is incorrect because Meiosis creates a HALF set of chromosomes (or just half than the original amount).
D. is incorrect because DNA is not produced during meiosis.
Answer: Muscles
Explanation:
When muscles aren’t used for long periods of time, the body will then break it down to conserve energy.
Answer:
The correct answer is option A. It answers scientific questions as accurately and completely as possible.
Explanation:
The scientific method or the process is a process that helps in answering the scientific question about the natural world phenomenons and acquire knowledge. This process involves different scientific steps that follow in order to answer as accurately and completely as possible.
The scientific process involves these steps in order - observation, forming a question, making a hypothesis, experiment to test, analyze the experiment data and result, and conclusion based on analyzing.
Thus, the correct answer is - A. It answers scientific questions as accurately and completely as possible.
