Answer:
when the size of a star increases, luminosity of star also increases.
The color of a star is decided by the surface temperature of the star and the temperature of a star depends on the size of star.
The smaller stars have low temperature and they are usually red (Proxima Centauri - red dwarf star).
The massive stars have higher temperature and they are usually blue (for exaple Zeta Puppis - Blue supergiant star).

wedWhat causes cells in living organisms to be different from one another?
O A An organism evolves new cell types in response to its environment
O B. The brain of an organism sends a signal to its cells to differentiate when the organismis in danger.
O c The DNA of an organism moves from one cell to another, allowing different cells to have different functions
O D. An organism expresses different genes at different times in development, causing cells to be specialized
Explanation:
The cell types in a multicellular organism become different from one another because they synthesize and accumulate different sets of RNA and protein molecules. They generally do this without altering the sequence of their DNA.

Marine Populations Lab Report Instructions: In the Marine Populations Lab, you helped gather data to evaluate Sebastian's Snorkel Spot's claim that a new factory is polluting the coral reef. Record your observations in the lab report below. You will submit your completed report. (30 points possible) Name and Title (1 point) Include your name, teacher's name, date, and name of lab. Objective(s) (2 points) In your own words, what was the purpose of this lab?
Answer:
The procedure is given below.
Explanation:
First we record the data of the pollutants that is releasing from the factory. Record the population of the coral reef which are not affected from these pollutants then take the data again and record the population of coral reef that is affected from the pollutants. If the population of coral reef that is affected from that pollutants increases it means that the pollutants damaged the coral reef population at higher rate. The purpose of this lab is to find out the negative effects of pollutants that is released from the factory on coral reef.

1. New chromosomes remain attached to
cell membrane
2. Proteins check for errors
3. Starts at one place
4. Proceeds in two directions
5. Copies of DNA condense into
chromosomes that separate
6. Starts at many places
Answer:
1. New chromosomes remain attached to cell membrane - Both
2. Proteins check for errors - Both
3. Starts at one place - Prokaryotes
4. Proceeds in two directions - Both
5. Copies of DNA condense into chromosomes that separate - Both
6. Starts at many places - Eukaryotes
Explanation:
The difference between prokaryotic and eukaryotic DNA replications is associated with the origins of replication, that is, the locations where replication starts. While in eukaryotic DNA, the origin of replication occurs in several places along the strands of DNA, replication in prokaryotic DNA has a unique origin of replication.
Replication of a cell refers to the formation of the two alike copies of DNA it is crucial for biological legacy, cell growth and division.
The process of replication in prokaryotes and eukaryotes somewhat contrasts from each other.
1. New chromosomes remain attached to cell membrane - Both in prokaryotes and eukaryotes.
In prokaryotes, the single circular chromosome remains attached to the cell also in eukaryotes chromosomes remain attached to the nuclear envelope.
2. Proteins check for errors - Both in prokaryotes and eukaryotes.
Although the process of formation of proteins is different proofreading occurs in both types of organisms.
3. Starts at one place - Prokaryotes.
Replication in prokaryotes originates from only one place while eukaryotic replication can occur from multiple positions.
4. Proceeds in two directions- Prokaryotes.
Replication in prokaryotes is bidirectional and advances in two directions.
5. Copies of DNA condense into chromosomes that separate - Both in prokaryotes and eukaryotes.
DNA condenses in the nucleoid which later gets separated.
6. Starts at many places - Eukaryotes.
In eukaryotic replication, the DNA strand has multiple sites of origin and the replication can occur at multiple positions.

Fisherman in a certain region have noticed a significant decrease in the biodiversity of fish species present in a local body of water. This has caused a decrease in the variety of fish available for consumers in the region. Which of the following changes has most likely caused this change in biodiversity?
A.
an increase in fish reproduction rates
B.
the introduction of an invasive species
C.
a decrease in water pollution
D.
a prolonged period of increased rainfall
Answer:
B
Explanation:
The introduction of an invasive species makes sense, because invasive species can wipe out mulitple native species leaving less resources for the native fish, and thus, decreasing biodiversity. A great real life example of this would be the Lionfish.

C. Only animals have net production.
d. Only plants have net production.
Please select the best answer from the choices provided
Ο Α

Answer:
b. Net production is always less than gross production.
Explanation:
The main production i.e. done in ecology would do the production in the organic compounds with the help of photosynthesis. The gross production is the value i.e. generation of organic compounds by producers while the net production is the value of organic compounds i.e stored by producers. It should be lower than the gross production as the plants are not able to store large number of organic compounds than they generated

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.

Which of the following best describes the genes of offspring of organisms that reproduce sexually?
Answer:
Each of the offspring is genetically unique and received some of its genetic
Explanation:
While reproducing sexually, The zygote receives half of the gametes of male organism while half of the gametes of female organism. This constitutes to the total number i.e. 46 chromosomes.
While the zygote receive half from male and half from female, This means that the offspring produced by the zygote will have both the characteristics in common of the male as well as female. Remember that, Chromosomes contain gene which are particularly responsible for characteristics.
So, Each of the offspring is genetically unique and received some of its genetic information from each parent, so each has some traits in common with each parent.
