Answer:
B. Codon
Explanation:
Codon refers to nucleotide triplets of mRNA that serve to specify the amino acid sequence of proteins. There are total 64 genetic code that specify 20 standard amino acids found in proteins. All codon together make genetic code. For example: AUG is codon that specify amino acid "methionine". AUG codon also serve as initiation codon during initiation of protein synthesis.
A three-letter sequence of mRNA that encodes for specific amino acid is called a codon. Therefore, option (B) is correct.
A codon is a set of three nucleotides in mRNA that tells which amino acid should be added to a protein. There are 64 genetic codes that specify the 20 standard amino acids present in proteins.
The genetic code is made up of all the codons together. As an example: The codon AUG specifies the amino acid "methionine". The AUG codon can be used as an initiation codon when starting protein synthesis.

What type of inertia and resilience is exhibited by grassland and rainforest?
Both, the grasslands and the forests exhibit high resilience to lot of exposure to sunlight. They are both found at places where there is lot of sunlight throughout the year, so they had to adapt to be able to witstand such intense sunlight. The grasslands also exhibit high resilience to droughts, as they can be found at regions where there's prolonged periods of drought. The rainforests, on the other hand, have developed high resilience to water, as they occupy regions where there's large amounts of water, more than the plants actually need, so it is crucial for them to be able to take in a lot of water, but also to be able to stop the intake of it.
List some general characteristics of producers and list a few examples.
A producer is like... a green plant or bacterium (plural for bacteria) and it's part of the first level of the food chain. Phototrophs and chemotrophs are two major producers. Phototrophs use the energy from the sun to convert carbon dioxide into carbohydrates, in other words, photosynthesis. Chemotrophs are almost microscopic- they are found in places where water and light are scarce (or rare) or even not there at all.
Sorry if this isn't any help... I'm trying my best, I don't know much. But if it does help, you're welcome! Have a nice day!
Answer:
Plants receive energy from the sun. Plants are also called producers.
All green plants are called producers as they are the main thing that produces food. They are at the bottom of the food chain.
Producers make food by photosynthesis, which is possible because of the chloroplasts found in the plant cells.
(Chloroplasts are the organelles within the plant cell where photosynthesis takes place. And it also gives a plant green color)
Whenever eaten, usually by primary consumers, they get the energy stored in the plant from the sun, fufilling it's role in the food chain.
If there were no producers, there wouldn't be a food chain, and we would already be dead.

The. diagram shows an event that occurs during. meiosis.What is the result of this event?
The result of this event in meiosis is the formation of genetically unique haploid daughter cells.
The event depicted in the diagram represents a crucial step in meiosis, a specialized cell division process that leads to the formation of haploid daughter cells. Meiosis is essential for the production of gametes (sperm and egg cells) with half the chromosome number of the parent cell, which is crucial for sexual reproduction.
During meiosis, there are two successive divisions: meiosis I and meiosis II. The event in the diagram corresponds to meiosis I, specifically the process known as "homologous chromosome pairing and crossing over."
The outcome of this event is the formation of genetically unique haploid daughter cells after meiosis I. These daughter cells have a combination of genetic material from both parents, thanks to the crossing over process. Subsequently, meiosis II further divides these haploid cells to produce four distinct gametes, each with a unique combination of alleles. This genetic diversity among gametes is essential for sexual reproduction and contributes to the variation seen in offspring.

The DNA sequence of the West Indian Ocean coelacanth is closest to which species
The DNA sequence of the West Indian Ocean coelacanth is closest to humans. This is based on our shared evolution, where the coelacanth branched off relatively early in the evolutionary path leading to modern four-limbed vertebrates, including humans.
Explanation:The DNA sequence of the West Indian Ocean coelacanth is closest to humans among all modern species. The coelacanth, often referred to as a lobe-finned fish, belongs to the Osteichthyes clade and is highly significant in the field of evolutionary biology. Resembling the transitional stage from fish to tetrapods (four-limbed vertebrates), their DNA provides valuable insights into our own evolutionary history. It shares more homology with vertebrates, especially tetrapods, than with any other fish.
The DNA sequence held by coelacanths today would have branched off the path leading to modern tetrapods relatively early in our shared evolutionary history before the development of categories like reptiles, birds, amphibians, and mammals. This makes its DNA sequence closest to early tetrapod ancestors, tying it more closely to humans than even certain other contemporary fish species.

They map the location of an earthquake’s focus.
They use one reading to determine the location of an epicenter.
They measure the difference between the arrival times of surface waves.
Answer:
A. They often compare information from all over the world.
Answer:
The correct answer will be they often compare information from all over the world.
Explanation:
A seismograph is an instrument which is used to detect and record the waves produces during an earthquake.
Earthquakes generate a series of seismic waves which travel radiate through the Earth. These waves travel in two forms- P-type or primary waves and S-type or secondary waves.
Geologist uses a simple method for locating an earthquake by finding the time interval between the P- and S-wave arrived at various seismograph stations. the distance between the earthquake point and station is then calculated from travel-time curves and standard travel-time tables. Arcs are drawn on the globe and mark the epicentre. They compare the data with the existing data and recorded data all over the world.

What three processes happen in every geological period?
Answer:
Mass extinctions, Wegenerian cycles, and the emergence of new life forms
Explanation:
Answer:
The correct answer is mass extinctions, Wegenerian cycles, and the emergence of new forms of life.
Explanation:
Every geological period is featured by the occurrences of Wegenerian cycles, mass extinction, and the origination of novel forms of life. The boundaries of the majority of geologic periods are generally mass extinction periods and this mass extinction stimulates the formation of new forms of life.
At the time of the geologic period, an array of tectonic activities plays an essential part as a consequence of the internal functioning of the Earth. The splitting of the continents takes place and arising of new landform at the plate boundaries takes place. This is termed as Wegenerian cycle.

What is the relative humidity percentage when the “real feel” is 108 degrees F and the temperature is 96 degrees F?
Answer:
The answer is B. Relative humidity percentage will be 50 %.
Explanation:
Relative humidity is the percentage of water vapors in the air at a particular temperature compared to the how much it can hold at that temperature. if the relative humidity is high (100%) we feel hotter than the actual temperature because water will not evaporate due to air saturation. in this case as the real feel is 108 F at 96 F the relative humidity will be 50 %.
Final answer:
To find the relative humidity based on the 'real feel' temperature of 108 degrees F and an air temperature of 96 degrees F, one would use a Heat Index Chart or calculator. However, without additional information on the actual humidity level, it's not possible to determine the exact relative humidity percentage from just these temperatures.
Explanation:
The question about calculating the relative humidity when the "real feel" is 108 degrees F and the temperature is 96 degrees F requires knowledge of the Heat Index and water vapor density. The Heat Index is a measure that takes into account the relative humidity and temperature to determine how hot it actually feels. To determine the relative humidity given these temperatures, one would typically refer to a Heat Index Chart, which correlates temperature and humidity levels with the perceived temperature. However, without knowing the actual relative humidity or having access to a Heat Index Chart, the exact relative humidity percentage cannot be determined from just the "real feel" and air temperature. Normally, the relative humidity can change as the temperature changes, if the water vapor density remains constant.

If two inedible insects share common colors, they may be warning a predator. This type of defense is called _____. Müllerian mimicry Mallerina mimicry Batesian mimicry
Answer:
Mullerian mimicry
Explanation:
The Mullerian mimicry is a type of mimicry where two or more organisms that are not closely related have mimicked each other for the benefit of all of them. This occurs usually at species that are not closely related, but are similar in size and often in shape. Both species have a proper defense mechanism, being very toxic, containing some acids, being uneatable, but in order to avoid injuries or mistaken attacks, they have also developed a warning signal, usually manifested through their coloration. Both species develop the same type of coloration and patters, making them look almost identical. This is for the benefit of both species, as the predators that they have in common will avoid both species by thinking that it is only one species that is not good for eating, thus having it more easy for remembering and avoiding, especially when it comes to the younger individuals of the predators.
Answer:
Mullerian
Explanation:
Mullerian mimicry is one in which BOTH the mimic and the model are BOTH dangerous to the potential predator and there is no distinction between the mimic and the model.
both dangerous to the potential predator = two INEDIBLE insects, as the question is worded. was correct after graded in ody ssey

the whale shark has rows of teeth despite being a filter feeder. what’s the best explanation of this feature?
A. the whale sharks teeth are an example of vestigial structures, if an inherited feature is no longer needed but also not harmful, there’s no evolutionary pressure to get rid of it
B. the whale sharks teeth are an example of of analogue structures. teeth exist in almost every sea creature, and the whale would be at a defensive disadvantage without them.
C. the whale sharks teeth are an example of homologous structures. other mammals also have teeth, and different teeth in humans have different shapes to serve different functions.
D. the whale sharks teeth are an example of embryonic structures. the teeth buds develop early enough in embryogenesis that the whale shark is still born with teeth.
Answer:
not sure i think a!
Explanation:
The correct answer is A The whale sharks teeth are an example of vestigial structures, if an inherited feature is no longer needed but also not harmful, there’s no evolutionary pressure to get rid of it
Explanation:
In biology, a vestigial structure refers to certain features such as organs or even behaviors that do not have a function or purpose in an organism but are still preserved usually because they do not represent a disadvantage for the organism. This occurs in the case of whale sharks teeth that despite being filter feeders, which means they feed on small organisms such as plankton they still have teeth, that they do not use for feeding or any other function, do not represent a harmful feature but might have a function in the past. Therefore, the best explanation for the teeth of whale sharks is that these are an example of vestigial structure, that was inherited but are not harmful and therefore they are still preserved as there is not an evolutionary pressure to get rid of them.
