what is ecosystem ?
An ecosystem can be defined as a community of living organisms concurrence with non-living components, interacting with each other in an environment.
The structure of an ecosystem composed of both biotic and abiotic components which include the distribution of energy in our environment, climatic conditions prevailing in that specific environment.
The structure of an ecosystem can be divided into two components such as Biotic Components and Abiotic Components
both biotic and abiotic components are interrelated with each other in an ecosystem,. it is an open system where the flow of energy and components occur throughout the boundaries.
The functions of the ecosystem include regulates the essential ecological processes, responsible for the cycling of nutrients between biotic and abiotic components, maintains a balance among the various trophic levels in the ecosystem.

use an analogy to explain the sequence of events in the replication of DNA
Answer:
- There are three main steps to DNA replication: initiation, elongation, and termination.
- In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.

How does meiosis create four daughter cells from one parent cell?
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. ... The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Explanation:
Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse. Homologous chromosomes exchange bits of DNA to create genetically unique, hybrid chromosomes destined for each daughter cell
6. Asparagine and Methionine are what type of molecule?
Answer:
Asparagine is the amide of aspartic acid. The amide group does not carry a formal charge under any biologically relevant pH conditions. The amide is rather easily hydrolyzed, converting asparagine to aspartic acid. This process is thought to be one of the factors related to the molecular basis of aging.

9. Select ALL of the following that would increase the reaction below, resulting in the formation of more products.
A:Increasing the temperature
B:Increasing the concentration of lipids
C:Adding an enzyme that forces the molecules to collide in the correct orientation
D:
Decreasing the reactant concentration
Answer:
A: Increasing the temperature
B: Increasing the concentration of lipids
C: Adding an enzyme that forces the molecules to collide in the correct orientation
Explanation:
Temperature plays a very important role in the chemical reaction as it increases the rate of reaction and allows the formation of more products.
Increasing the concentration of lipids will also promote the production of more products because lipids function as energy-storage molecules and chemical messengers which can give more energy to the reaction.
Adding an enzyme will definitely allows the formation of more products as enzymes are responsible for accelerating chemical reactions by increasing collision between reactants. More is the collision more products will form.
Hence, the correct answers are:
A: Increasing the temperature
B: Increasing the concentration of lipids
C: Adding an enzyme that forces the molecules to collide in the correct orientation

How does the theory of natural explanation explain the medical phenomenon of antibiotic resistance?
Answer:
Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can then transfer the genetic information in a horizontal fashion (between individuals) by plasmid exchange.
