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.

which of the following accurately describes the relationship between the lungs trachea and alveoli in the respiratory system.
A. They work together to transport blood.
B.They work together to allow gas exchange.
C. They work together but with completely separate functions.
D. They work together to obtain nutrients to deliver to cells.
B
the lungs is an organ of respiration,while the trachea allows passage of air from the larynx to the bronchi Of the lungs.. the alveoli is a tiny air sac that takes the oxygen and allows the body going
The trachea divides into a left and right bronchus inside the lungs. These further separate into bronchioles, The tiniest bronchioles have tiny air sacs at their ends. They are known as alveoli. Thus, option B is correct.
What is the role of trachea and alveoli?The trachea splits into the right and left principal bronchi at the mediastinum at the level of the fifth thoracic vertebra.
The bronchi split off into progressively smaller channels before coming to an end in tiny air sacs known as alveoli.
During this process, oxygen diffuses from the alveoli to the blood through the alveolar walls' capillaries (small blood vessels).
Hemoglobin in red blood cells absorbs oxygen as it enters the bloodstream.
Therefore, trachea and alveoli in the respiratory system work together to allow gas exchange.

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 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.

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

Think of an example from your own life such as school, sports, or an extracurricular activity. Develop an analogy to explain why specialization and communication are as important to that activity as they are to a cell
Answer:
In a school environment, there are different teachers who teach a different subject, administration controls all the school functions and affairs other than teaching. Other staff such as janitors, bus drivers carry out necessary functions.
In the schools, there are various specific tasks carried out by specific teaching or non-teaching staff. In the cell, a similar condition found as they show specialization and communication as various cell organelles are specific to a specific function and communicate with one another.

Tides are the cycle of rising and falling
ocean water that repeats approximately
A every 24 hours
B every 12.5 hours
C every 25 hours
Devery 6.25 hours
Answer:
B. every 12.5 hours
Explanation:
Tides can be defined as the rise and fall of water level in water bodies such as lakes and oceans due to the gravitational force of attraction exerted by the moon on earth. The side closest to the moon creates a bulge of water known as high tide. Low tides are generally experienced when a sea level is not within the bulge.
Hence, tides are the cycle of rising and falling ocean water that repeats approximately every 12.5 hours.
