Which statement describes a characteristic of a spiral galaxy?
Answer:
If your just looking for a description here you go.
Explanation:
Most spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive black hole. Approximately two-thirds of spiral galaxies also contain a bar structure through their center, as does the Milky Way.

Compare the structure of proteins and nucleic acids by answering the following:
What atoms are found in proteins, and what atoms are found in nucleic acids?
What are the monomers that make up a protein, and what are the monomers that make up a nucleic acid?
Answer in complete sentences.
PLEASE HELP ASAP AND PLEASE DONT COYP AND PASTE FROM GOOGLE
The formation of proteins is guided by the blueprints of nucleic acids. Protein is composed of C H O N and S while Nucleic acids contains C H O N P. Amino acids and nucleotides are their respective monomers.
What are protiens and nucleic acid?Protein, a complex substance in all living things. Proteins are vital to life's chemical processes. Proteins can function as structural material (collagen, keratin), enzymes, hormones, oxygen transporters (hemoglobin), antibodies, or gene expression regulators.
In all living things, including bacteria and viruses, nucleic acids play a crucial role as large biomolecules. To store and express genomic information is a primary role of nucleic acids. Information for protein synthesis is stored in a form of DNA called deoxyribonucleic acid.
Thus, nucleic acid and proteins are significantly different from each other.

What is cellulose? Why is it indigestible for most animals (including humans)?
Answer:
a cellulose is the main substance that makes up the cell walls and fibers of plants
Explanation:
cellulose is ingigestible to most animals because animals do not have the enzymes needed to hydrolyze the glycosidic linkages between the monomer units
The correct answer is - cellulose is a polysaccharide that is indigestible for most animals as they lack bacteria that produce enzyme help in digestion of cellulose.
Cellulose is a structural polysaccharide that is present in most of the plant's structure as present in the cell wall of plant cells and provides support and help in standing in an upright position.
Humans and most animals lack the enzyme essential to digest cellulose in their bodies.Many plants such as hay and grasses have cellulose in the abundance.Starch is easily digested as it is also a polysaccharide but is storage-based. Cows, ox, horses, and such animals can digest cellulose due to having bacteria in their gut that produce enzymes.Thus, the correct answer is - cellulose is a polysaccharide that is indigestible for most animals as they lack anaerobic bacteria that produce enzyme help in digestion of cellulose.

14. What is the purpose of doing multiple trials in an experiment?
Answer:
This question is incomplete as it lacks options, the options are:
A. To get as much data as possible.
B. To make sure the procedure is done correctly every time.
C. Eliminate observations that are not typical and reduce error
D. To double-check the results so they are the same each time
The answer is C.
Explanation:
An experiment is carried out to test a hypothesis, which is a predictive explanation/solution to a problem. The experiment aims at accepting or rejecting the hypothetical claim. However, the experiment needs to be conducted more than once, which is called MULTIPLE TRIAL.
An experiment is conducted multiple times in order to improve how accurate the results are. This means that the error in the experimental results is brought to minimal by replicating or doing it multiple times. Hence, the purpose of conducting an experiment in multiple trials is to eliminate observations that are not typical and reduce error

lipid molecules?
Lipid molecules are polar because they mix poorly
with liquids, such as water.
Lipid molecules are polar because they adhere
tightly to smooth surfaces, such as paper.
Lipid molecules are nonpolar because they repel
water molecules, which also are nonpolar.
Lipid molecules are nonpolar because they repel
water molecules, which are polar.
Answer:
lipid molecules are non polar because they repel water molecules, which are polar
Explanation:
A lipid is an organic compound that is insoluble in water. A lipid consists of hormones, waxes, oils, fats. Also, a lipid is a form of chemical messengers and energy-storage molecules. Lipids are basically insoluble bio molecules.

If a DNA strand lias a sequence GTA, what will be the tRNA anticodon sequence?
A. GUA
B. CAU
C. GTA
D. CAT
Answer:
CAU
Explanation:
DNA is a nucleic acid that carries the genetic material. If the DNA sequence has GTA bases, then the tRNA anticodon sequence will have codon GUA. Thus, option A is correct.
What is the tRNA anticodon sequence?
tRNA anticodon sequence includes the three nucleotide bases complementary to the codons presented on the mRNA sequence.
The mRNA is complementary to the DNA template (GTA) and will have a sequence as "CAT." The tRNA has anticodons that, in turn, are complementary to the mRNA and will have a sequence of "GUA."
Therefore, GUA is the tRNA anticodon sequence.

(2) cells carry on the basic life functions of living organisms
(3) cells contain structures that carry on life functions
(4) most cells cannot reproduce
Answer:
(4) ik im almoset 3 years late
Explanation:
The statement about cells that is not true is most cells cannot reproduce. Thus, the correct option for this question is D.
Who discovered the cell?An English Scientist Robert Hooke in 1665 first discovered a dead cell in a thin slice of the bottle under a microscope. Antony Von Leeuwenhoek discovered the living cell in 1674 with the help of an improved version of the microscope.
The word Cell is derived from the Latin word Cellula which refers to a little room. All living organisms are made up of one or more cells. So, the cell is considered the basic structural and functional unit of life.
Apart from this, two famous scientists named M. J. Schleiden and T. Schwann after a detailed study of plant and animal cells discovered a theory known as Cell theory.
Therefore, the statement about cells that is not true is most cells cannot reproduce. Thus, the correct option for this question is D.

What is the purpose of pain?
Yo! Bakugo here!
Pain serves as an alert to potential or actual damage to the body. The definition for damage is quite broad; pain can arise from injury as well as disease. Pain that acts as a warning is called productive pain.
Hope this helps!!
Simply put, pain alerts us to the possibility of tissue damage or the presence of an injury.
What is injury?Damage, harm, hurt, impair, and mar are a few popular words that are synonyms for injure.
All of these verbs mean "to effect injuriously," but the term "injure" connotes the infliction of harm to one's success, comfort, or success. severely hurt in an accident.
A framework states that injuries are caused by a variety of human variables. physical and social surroundings are influenced by agent, vehicle, and energy (like heat).
Simply defined, pain warns us when there may be an injury or potential tissue damage.
This can be physical or chemical, visible or invisible, occurring inside or outside the nervous system. Pain is the body's alert system, regardless of the fact that its characteristics may vary.
