What is produced by translation?
A. An amino acid
B. A strand of mRNA
C. A protein
O D. A strand of DNA
Answer:
c) A protein
Explanation:
The molecule that results from translation is protein -- or more precisely, translation produces short sequences of amino acids called peptides that get stitched together and become proteins. During translation, little protein factories called ribosomes read the messenger RNA sequences
A protein
What is translation ?
Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis.
What is produced by translation?
In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.

Give me a example of a vegan dinner and a vegan snack
And benefits of the vegan diet and negative aspects of the vegan diet
and do doctors recommended this diet
and statistics of the vegan diet
Answer:
a vegan dinner could be a meat free burger with vegan cheese and fries with a side of salad. a snack could be hummus with sliced veggies. a benefit of the vegan diet is reduced risk of high blood pressure and reduced risk of illnesses related to meat-based diets such as cardiovascular disease (if you eat healthily, unhealthy vegan meals are becoming more common.) a risk is that yiu need to keep a close eye on your diet. removing all animal products means you risk not getting enough nutrients from things you would normally eat and need to research lots of supplements. as foods such as tofu are becoming more popular, veganism is becoming less benefitial for the enviroment. forests are cleared to make way for tofu and meat substitute plantations. after humdreds of years, some animals need human interference. if we stop removing honey from domesticated bees hives, they will be unable to survive. if we juat didnt interfere from the start they would not need it, but back then we had no choice.
Answer:
sorry this is late (count that this is todays standards of food's and alot of this vegan meat stuff is out now)
Vegan dinner:
impossible burger with french fries
Vegan snack:
chex mix, any kind of chips besides ranch ones (or special vegan ranch ones)
Not many doctors recomend this diet, a lot of them push away from it, only because it prevents the person from getting healthy again and keeps them on medication, which brings more money into the feild.
There was a study called "The China Study" It was done in china and they found amazing results, finding that the people who ate soley rice and grains had 50% lower heart disease risk than others. Today, we can find many sources that lead to a 4% chance of getting heart disease one a vegan diet.
A good place to find a good doctor talking about this diet, and even saved his grandmother and made 2 books "how not to die" and "how to survive a pandemic" dr michael greger MD

I WILL REPORT IF U JUST DO IT FOR POINTS AND U JUST PUT NONSENSE
Answer:
1. The two main cell types are prokaryotic and eukaryotic. Prokaryotic cells lack a nucleus and other membrane-bound organelles.
2. Cytoplasm: Cytoplasm contains enzymes that break down waste. It also provides shape to the cell. Cytoplasm enables organelles to remain where they are.
Nucleus: The nucleus controls activity inside the cell. It also carries genes.
Mitochondria: Mitochondria generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate.
Endoplasmic reticulum: The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.
Ribosomes: The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make proteins.
Golgi apparatus: A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
Vesicles: Transport vesicles help move materials, such as proteins and other molecules, from one part of a cell to another.
Lysosomes: A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
Cell membrane: The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
3. An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
4. Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. These structures include: chloroplasts, the cell wall, and vacuoles.

How do other organisms benefit from other biotic and abiotic things in tropical rainforest?
Answer:
All of the biotic factors are dependent upon the abiotic factors. ... Water, sunlight, air, and the soil (abiotic factors) create the conditions that allow rain forest vegetation (biotic factors) to live and grow. Organisms like monkeys, bats, and toucans eat the vegetation supported by the abiotic factors.
Explanation:
Biotic things are stuff like sunlight, air, dirt, etc. Plants and animals are abiotic. Abiotics benefit from biotics because they use the air, light, and dirt to function in everyday life.

Each Codon in mRNA matches up with a specific.....
O amino acid
O protein
nucleotide
O lipid
Previous
Answer:
O amino acid
Explanation:
tRNAs bring their amino acids to the mRNA in a specific order. This order is determined by the attraction between a codon, a sequence of three nucleotides on the mRNA, and a complementary nucleotide triplet on the tRNA called an anticodon. This anticodon also specifies the particular amino acid that the tRNA carries.
what is the difference between evolution and natural selection?
You will need two answers One that you can find online and one that is a personal answer.
Answer:

Explanation:
-Evolution is a gradual change in the inherited traits of a population over many generations. Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes.
- Evolution is the precessions by which population changed over time whereas natural selection is the process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do

Evolution is any change in the heritable traits within a
A. generation
B. population
C. individual
Answer:
B. population
Explanation:
CORRECT
Evolution is any change in the heritable traits within a population. Therefore, option (B) is correct.
What is evolution?Evolution is the process by which populations of organisms change over time through the gradual accumulation of genetic variations. It is the central concept of modern biology and provides a framework for understanding the diversity of life on Earth.
Evolution occurs through the mechanisms of natural selection, genetic drift, gene flow, and mutation. Over time, genetic variations that confer a survival advantage in a particular environment become more common in a population, while those that are detrimental or neutral are selected against.
This process can lead to the emergence of new species, as well as the extinction of others. The study of evolution has practical applications in fields such as medicine, agriculture, and conservation, and helps us understand our place in the natural world.

Sperm are produced in the glands sperm duct. testes. urinary bladder.
The testes. A pair of male reproductive glands called the testes can be found in the scrotum, which is a sac-like structure that is found on the exterior of the body.
Sperm and the male hormone testosterone are both produced in the testes, which are responsible for the function of the testes. When the sperm have been created, they pass via a number of ducts, such as the vas deferens, the epididymis, and the ejaculatory ducts, before being expelled from the male organ during the process of ejaculation. On the other hand, the urine bladder is a component of the urinary system, but it does not contribute in any way to the creation of sperm.

Daughter cells formed by mitosis have exact copies of the parent cell's DNA. What process ensures that is possible?
Daughter cells formed by mitosis have exact copies of the parent cell's DNA. The anaphase process ensures that is possible.
What is mitosis?Cell division occurs during mitosis. All eukaryotic cells go through the process. There are four stages to the process. The cell divides during the procedure. A daughter cell that is identical to the parent cell is created.
Prophase: This is mitosis's initial phase. At this point, the chromosomes begin to compress and the cell begins to break.
This is the second phase, or metaphase. The chromosomes align in the spindle fiber during this stage, and a checkpoint is also established.
Anaphase: At this time, the sister chromatids separate, align, and the chromosomes divide.
The final phase is known as the telophase. The nuclear membrane developed as the nucleus closed.
Therefore, the process that ensures the daughter cells formed by mitosis have exact copies of the parent cell is the anaphase.
