Answer: The Golgi Apparatus
The Golgi apparatus is a set of flattened, membrane-bound sacs that serve as the packaging and distribution center of the cell.
Explanation:
The packaging and distribution center of the cell is the function of the golgi apparatus. Golgi apparatus prepares proteins and lipids in cell. Thus, the correct option is D.
What is Golgi apparatus?Golgi body is also known as a Golgi apparatus. It is a cell organelle which helps in processing and packaging of proteins and lipid molecules, especially the proteins that are destined to be exported out from the cell.
Stack of small flat sacs formed by membranes inside the cell's cytoplasm. Golgi apparatus prepares proteins and lipids for the use inside and outside of the cell.
Therefore, the correct option is D.

what three animals are closley related to a tiger
Answer:
The tiger's closest living relatives were previously thought to be the Panthera species lion, leopard, and jaguar.
Explanation:
Results of genetic analysis indicate that about 2.88 million years ago, the tiger and the snow leopard lineages diverged from the other Panthera species, and that both may be more closely related to each other than to the lion, leopard and jaguar. The geographic origin of the Panthera is most likely northern Central Asia or the Holarctic region. The tiger–snow leopard lineage dispersed in Southeast Asia during the Miocene.
Panthera zdanskyi is considered to be a sister taxon of the modern tiger. It lived at the beginning of the Pleistocene about two million years ago, its fossil remains were excavated in Gansu province of northwestern China. It was smaller and more "primitive", but functionally and ecologically similar to the modern tiger. It is disputed as to whether it had the striping pattern. Northwestern China is thought to be the origin of the tiger lineage. Tigers grew in size, possibly in response to adaptive radiations of prey species like deer and bovids, which may have occurred in Southeast Asia during the Early Pleistocene.

Carbohydrates have chemical bonds that are a good source of energy for living things. A monosaccharide is a carbohydrate made by plants when energy from the sun combines water and carbon dioxide.
How are the two other types of carbohydrates formed? Give examples of each type.
Explanation:
The other two types of carbohydrates, disaccharides and polysaccharides, are formed when monosaccharides link together to form larger molecules and chains. A disaccharide is a sugar that is made from two monosaccharides (di=two). For example, sucrose is a disaccharide that is made from the bonding of glucose with fructose, which are both monosaccharides. Sucrose is known as table sugar, and is found naturally in plants. Polysaccharides are large, complex molecules that are formed when monosaccharides or disaccharides link together in repeating units to form long chains. The most abundant polysaccharide in the world is cellulose, the substance that makes up the cell wall of plant cells. Starches are also examples of polysaccharides, and these are stored in plants such as grains, corn and wheat.
All living organisms must obtain energy in order to survive, and most organisms rely on carbohydrates as energy sources. These molecules are made through the process of photosynthesis, and they store the sun's energy within them.
Please Help! What molecules need to travel through ATP synthase to help it create ATP?
Answer:
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

What is RNA polymerase?RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.

Cholesterol is synthesized by all animal cells and is an essential structural component of animal cell membranes. Cholesterol is the most common steroid and is mainly synthesized in the liver. Cholesterol also serves as a precursor for several important biological compounds including all, EXCEPT: A) insulin B) vitamin D C) bile salts D) testosterone
the answer is insulin. because the precursor for insulin is called pro insulin
Cholesterol does not serve as the precursor for insulin. So the correct option is A.
What is cholesterol?Cholesterol is a wax-like substance. Cholesterol is considered to be bad among the general public but it is not inherently “bad.” Our body needs for building cells and making vitamins and several other hormones. Cholesterol levels, in excess, can pose a problem.
Cholesterol can come from two sources. These are synthesized by the liver and from foods from animals. The liver produces all the required cholesterol but the remainder is obtained from foods. For example, meat, poultry, and dairy products of them contain dietary cholesterol.
These are the same foods that are also high in saturated fats and trans fats. These fats cause the liver to make more cholesterol than required or more than it normally does. This added production of cholesterol, for some people, means they go from a normal level of cholesterol level to unhealthy level of cholesterol.
Therefore the correct option is A.

10: For the fermentation experiment: List the 4 reagents used and their function
Answer:
yeast, invertase, bacterial culture, maltase
Explanation:
Fermentation is defined as a metabolic organic substance are chemically changed with the help of enzymes. The process of fermentation is used for the production of food such as bread and beverages such as alcohol.
Reagents are the chemical used to process a chemical reaction in an expriment. So reagents used in fermentation are yeast, invertase, bacterial culture, maltase.
Yeast is a fungus used for alcohol production that that is used to improve the nutritive value of the beverage.
Invertase is an enzyme that is used to cleave the glycosidic linkage between fructose molecules and glucose.
Bacterial culture are use to ferment the process that produces alcohol and carbon dioxide.
The enzyme maltase breaks the bond between maltose and convert it into glucose.

On May 18, 1980, Mount St. Helens in Washington State experienced a huge volcanic eruption after a magnitude 5.1 earthquake. During the eruption, hot ash and pumice poured down the west, south, and east sides of the mountain, melting the snow and ice at the top of the volcano and producing volcanic mudflows. Which type of process first occurred in the ecosystem around Mount St. Helens after it erupted?
Answer:
primary succession
Explanation:
Primary succession starts in regions where there is no soil or where the soil is incapable of sustaining life due to any recent lava flows or newly formed sand dunes. Primary succession may lead to the formation of islands on land formed from glacial retreats or on new volcanic rock.

Which of the following food chain correctly represents the flow of energy in a living system? NEED ASAP
Answer:
B-> Starts with Producer
Explanation:
It's in the name. You will just have to memorize the vocabulary.
Option (B) correctly represents the flow of energy in a living system because food chain starts with a producer.
What is a food chain?Wild food chain shows who eats whom. Every living thing—from algae to blue whales—needs food. Each food chain is an energy and nutrient channel in the ecosystem.
In food chains, organisms are categorised into trophic levels. Producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers roughly correspond to these levels.
Autotrophs produce their own nourishment. They start every food chain. Plants and single-celled creatures are autotrophs. Nearly all autotrophs make "food" (glucose) from sunlight, carbon dioxide, and water through photosynthesis.
