Identify the major players shown in the simulation: mRNA, Codon, Amino Acid, tRNA, anticodon, ribosome.
Answer:
mRNA, tRNA and ribosome
Explanation:
mRNA, tRNA and ribosome are the major players because they perform a very important functions. Messenger RNA (mRNA) is a molecule in cells that carries instructions in the form of codes from the DNA to the sites of protein synthesis which is a ribosomes. Transfer RNA (tRNA) is a type of RNA molecule that helps in decoding a messenger RNA (mRNA) into a protein. Ribosome is an organelle present in the cell that is responsible for the production of proteins according to the instruction given by DNA.

What process creates stalagmites? Group of answer choices Rivers carrying rocks down a mountain Windblown sand shaping large rocks Minerals being deposited as water drips Glaciers pushing large rocks
Answer:
Minerals being deposited as water drips.
Explanation:
Stalagmites grow on the floor of a cave. The process that creates them starts with the filtration of rainwater drops through the rock picking gases and minerals, amongst these ones is calcite. When the drops containing these elements pass through the rock and are in contact with the air, a chemical reaction happens. As a consequence, the calcite precipitate on the floor of the cave. This process has to happen many times to form a stalagmite.

Bacteria are capable of
reproducing quickly. Explain how
this adaptation is beneficial in
their ability to become resistant
to antibiotics
Answer:
Antibiotics, also known as antimicrobial drugs, are drugs that fight infections caused by bacteria. Alexander Fleming discovered the first antibiotic, penicillin, in 1927. After the first use of antibiotics in the 1940s, they transformed medical care and dramatically reduced illness and death from infectious diseases.
The term "antibiotic" originally referred to a natural compound produced by a fungus or another microorganism that kills bacteria which cause disease in humans or animals. Some antibiotics may be synthetic compounds (not produced by microorganisms) that can also kill or inhibit the growth of microbes. Technically, the term "antimicrobial agent" refers to both natural and synthetic compounds; however, many people use the word "antibiotic" to refer to both. Although antibiotics have many beneficial effects, their use has contributed to the problem of antibiotic resistance.
Antibiotic resistance is the ability of bacteria or other microbes to resist the effects of an antibiotic. Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm.

What is the main difference between primary succession and secondary succession?
Answer:
Primary succession in the first initial establishment of an ecosystem on a new layer of terrain (usually rock), whereas secondary succession is a re-establishment of an ecosystem OR simply any establishment of an ecosystem on a rock which was previously inhabited.
Explanation:
Primary succession is the very first establishment of an ecosystem on a new layer of terrain (usually rock) which was previously uninhabited by living organisms. Secondary succession can be thought of as a re-establishment of ecosystems on a terrain/rock which was previously inhabited but is no longer due to an ecological or environmental disruption.
Hope this helped!
Answer:
Primary succession is the progress of plants growing on bare lands, like a bulldozed area, a landslide, or even a solid rock. (Or a volcano.)
On the rock, lichens start, make a little soil, mosses start in the soil, make a little more, Spikemoss (a vascular plant) starts, traps and makes more soil, making a place for dry land plants, which trap and make more soil, eventually, after a very long time, giving rise to a mature forest over rock. The only way to tell that rock is the substrate is the forest composition
Secondary is from a place that has had a forest, and is either burned, farmed, or cut. Plants start very quickly from seeds, roots, tubers, and reforestation can take as little as 20 years, and maturity as little as 75.

There are different kinds of mutations. What can happened to the fruit

What takes place to the body of a fruit fly if the Hox gene is altered?When there is Homeotic mutations in fruit flies, Homeotic genes are said to be the reason or the option that is used in knowing the identity of some specific segments or structures of the body.
If an homeotic genes is said to be inactivated or when expressed in an unusual part of the body due to mutations, it may make the body segments to take on new form.
In Drosophila, that is the fruit fly, a Hox mutation can create a lot of changes such as an extra pair of wings, new a set of legs, etc.

Yeast is added to bread dough before baking. After several minutes, the bread dough rises. Use your experiment to explain how respiration of yeast is important for the baking process.
Answer:
The purpose of any leavener is to produce the gas that makes bread rise. Yeast does this by feeding on the sugars in flour, and expelling carbon dioxide in the process.
While there are about 160 known species of yeast, Saccharomyces cerevisiae, commonly known as baker's yeast, is the one most often used in the kitchen. Yeast is tiny: Just one gram holds about 25 billion cells. That amount of fungi can churn out a significant amount of carbon dioxide, provided it has the simple sugars it uses as food. Fortunately, yeast can use its own enzymes to break down more complex sugars—like the granulated sugar in the activity below—into a form that it can consume.
Make a yeast-air balloon to get a better idea of what yeast can do
Yeast is a unicellular fungus which undergoes anaerobic respiration to produce ethanol and carbon dioxide gas.
How does yeast fermentation work in bread-making?In a process known as fermentation, yeast consumes the sugar present in the dough to produce carbon dioxide and alcohol.The dough is kept in a warm area throughout the baking process.Fermentation occurs as a result of heat.However, if the temperature is too high, the yeast is killed during the cooking process.As the dough ferments, carbon dioxide is created and trapped as microscopic air bubbles. The expansion of carbon dioxide during baking allows the bread to rise higher. During the bread-baking process, the alcohol created during fermentation evaporates.This is how yeast fermentation plays a vital role in the baking process.

Explanation:
You didn't give the options and I couldn't get them online but based on the information given, the relationship is parasitism.
Parasitism is a refered to as a symbiotic relationship that exists between organisms such one organism, which is known as the parasite, either lives on the other organism which is called the host or lives inside it and causes the host harm.
In this case, the parasite benefits at the expense of the host. Examples of parasites include tick, fleas and tapeworms.
With regards to the question, the tapeworm causes people harm and benefits at the expense of its host.

Study the processes that makes cells work
Answer:
One cell divides into two in a process called mitosis. Mitosis produces two genetically identical “daughter” cells from a single parent cell. Another type of cell division, meiosis, creates four daughter cells that are genetically distinct from one another and from the original parent cell. Only a few special cells can perform meiosis: those that will become eggs in females and sperm in males
