Galaxy composition typically relate to the age of the stars in the galaxy
through Stars being able to form from dust and gas, so galaxies with
younger stars typically consist of higher proportions of dust and gas than
other galaxies.
Components of a StarDustGasThe age of stars are usually determined through the amount of gas and dust
present in them. Stars burn gas to emit light and the younger ones have
more proportion of gas present than the older ones. The older ones have
less proportions due to more gas being burned over time.
The stated facts therefore makes option C the most appropriate.

Monarch butterflies have brightly colored orange wings with black patterns on them, making them easily visible to birds that eat butterflies and moths, yet birds rarely eat the monarchs. Likewise, the monarch caterpillars are brightly striped yellow and white and black, and they also are rarely eaten by birds, although some wasps will attack them and feed them to their young. What can be inferred from these observations?
A. Monarchs must threaten and attack birds, but not wasps.
B. Monarchs have a way of discouraging bird predation that does not involve hiding.
C. Monarchs' wings are so colorful that most birds must find them difficult to eat.

if I subtract 20 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result
What is my number and how do you work it out?
The value of the unknown number is 10.5.
Let the unknown number = x
When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:
(x - 20)² = x² - 20
expand the equation;
x² - 40x + 400 = x² - 20
collect similar terms together;
x² - x² - 40x = -20 - 400
-40x = -420
[tex]x = \frac{420}{40}\\\\ x = 10.5[/tex]
Thus, the value of the unknown number is 10.5.

which adaptation do ferns, gymnosperms, and angiosperms have that mosses do not have?
Answer:
pollen and seeds
The adaptation do ferns, gymnosperms, and angiosperms have that mosses do not have they have seeds and pollen for reproduction.
What do mosses not have?Mosses make up the majority of bryophytic plants. They are small plants with a simple structure, they do not have conducting vessels, flowers and seeds.
Ferns have a vascular system that transports food, water and minerals to the upper parts through hair-like roots. Mosses do not have true roots or a vascular system. Instead, they absorb water and minerals from the soil where they grow.

Answer these questions about making a yogurt.
1) why is the milk pasteurized at the start of the process?
2) Why is the mixture of milk and bacteria incubated at 45 °C?
3) what causes the milk to thicken?
4) why does fermentation eventually stop?
5) Explain how making yogurt is a way of preserving the nutrients from milk.
It should be noted that milk is pasteurized at the start of the process in order to kill bacteria.
The mixture of milk and bacteria is incubated at 45 °C to kill the bacteria.The drop in pH causes milk to thicken. Fermentation is stopped when the alcohol concentration rises to a point where it kills the yeast cells.Lastly, making yogurt is a way of preserving the nutrients from milk as the bacteria ferment the milk thereby turning the lactose sugars to lactic acids.

1.) Using the information in the table below, determine the amino acid sequence or get is coded for by the mRNA sequence: AUG-UCU-GAU-UGG-UAC.
2.) What is the start codon? What are the 3 stop codons?
The amino acid sequence here is Met-Ser-Asp-Trp. The start codon is AUG, while the three stop codons are UAG, UAA, and UGA.
The triplets of nucleotides or codons in mRNA determine the order of amino acids that will be added to the protein during translation.
The start codon in the genetic code is AUG and it encodes for the amino acid methionine (Met).
The 3 stop codons in the genetic code are UAG, UAA, and UGA. These codons do not code for an amino acid.

Which ratio of surface area to volume is most efficient for a cell?
Answer:
Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.

A elephant cell has 20 chromosomes. how many chromosomes will the cell have just before mitosis begins in the elephant cell?
The elephant cell will have 20 chromosomes.
Cells undergo interphase before getting to the mitotic phase. At the S phase of the interphase, the amount of DNA in the cell is double by replication. However, the number of chromosomes remains intact.
Thus, the cell gets to the mitotic phase with the same number of chromosomes that is usually present in normal vegetative cells of the animal.

The given statement is :
True
The position of corals can be explained as:
The corals are both a primary producer as well as the consumer.They take energy from algae through the mutual relation between both organisms. The corals feed on planktons, zooplanktons and phytoplankton for energy so they are consumers.The algae living in coral make food for them and corals produce oxygen.

Hope this helps you !!the presence of a lophophore in a newly discovered species would suggest that the species ________.
Answer: the answer is has an exoskeleton
The lophophore is the feeding organelle in aquatic organisms. Its presence in a species suggests that the species is a suspension feeder. Thus, option D is correct.
What are lophophores?
Lophophores are the feeding organelles present in the marine invertebrates like Brachiopoda, Hyolitha, etc., of the Lophophorata group. They are used for respiration, brooding, and collecting food.
Suspension feeders use these lophophores to collect and feed on the suspended organic matter and particles in the water. Lophophorates are a major example of suspension feeders.
Therefore, the presence of the lophophores suggests the species to be a suspension feeder.

Viruses and bacteria can infect human cells. Bacteria are living organisms, while viruses are not. How do you think the treatment for viral and bacterial illnesses differ? How do you think they affect healthy body cells? Explain your response. NO PLAGIARISM WILL BE REPORTED IF SO.
Viral infections cause similar symptoms as bacterial infections. Antibiotics treat bacterial infections but do not treat viral infections. Some antiviral medicines are used to treat viral infections.
The misuse of antibiotics to treat a viral infection contributes to antibiotic resistance.
Antibiotics kill bacteria without damaging the body’s cells. They do so by interfering with how bacteria live and reproduce. Normal body cells work in different ways, so they’re not affected.
While antibiotics are effective in treating bacterial infections, they can also damage the immune system when used incorrectly or too frequently. Therefore, the doctor should prescribe antibiotics only when needed and sparingly.
