you take a summer vacation by the ocean in P.E.I. you love the ocean plants you see and you decided to bring some home for the fish tank. after a week or two, you notice that your plants are not thriving to live in your freshwater tank. use your knowledge you gained in this chapter to propose a reason for this
The reason that the plants are not thriving to live in your freshwater tank is due to slow growth, and lack of adequate lighting and carbon dioxide.
How to illustrate the informationFrom the information illustrated, during the summer vacation, the person saw the ocean plants and decided to bring some home for the fish tank. Plants require nutrients for the same reasons that animals do. They require them in order to germinate, grow, combat diseases and pests, and reproduce. Nutrients, like animals, are required in bigger, smaller, or trace amounts for the plant to be healthy.
Nitrogen is the growth ingredient responsible for green, leafy growth. Nitrogen, as a primary component of proteins, is found in every living cell. As a result, this nutrient is usually more responsible for stimulating plant growth than any other.
It was later noticed that after a week or two, the plants are not thriving to live in your freshwater tank. In this case, the important thing to do is to create a consistent light that will compensate for the cycle. The fact that the ocean water is salted and the nutrients gotten from the ocean is also another contributory factor to the changes noticed.

What is history of the earth?The evolution of the planet Earth from its creation to the present is the subject of Earth history. The major occurrences of Earth's past, which were marked by continuous geological change and biological evolution, have been better understood thanks to the work of nearly all fields of natural science.
The date of Earth's formation is 4.5 billion years ago (abbreviated Ga for gigaannum), and evidence points to the emergence of life earlier than 3.7 Ga. Although there is some evidence of life as early as 4.1 to 4.28 Ga, it is still debatable because it's possible that the so-called fossils didn't originate biologically.

Paleontologists find a fossil ape with long arms. What type of environment can they infer it inhabited?.
The type of environment can they infer it inhabited is Woodland.
Environments such as lush rainforests and hot and humid climates are also not good places for fossils to form. Similarly, rocky peaks are not good places for fossils to form without depositing fine sediments. This radiometric method is often used to date the crystals and glasses of rapidly cooled volcanic rocks such as volcanic ash.
The most common minerals dated this way are zircon and apatite. For example, fossils are more likely to be preserved in marine environments where rapid burial by sediment is possible. Less favorable environments include rocky peaks where the carcass collapses quickly or deposits little sediment to bury the carcass.

D The best answer for the question "Hibernation is an adaptation that helps animals to _______" is b. survive cold winters.
Hibernation is a survival mechanism that helps animals conserve energy during the harsh winter months when food and resources are scarce.
By lowering their metabolic rate, animals can slow down their bodily functions, reduce their energy expenditure, and survive for extended periods without food.
This adaptation allows animals to endure the cold and harsh conditions of winter, and it is especially useful for small mammals, such as squirrels, bats, and hedgehogs, who are unable to migrate to warmer areas.
Overall, hibernation is a remarkable adaptation that has helped many animals survive in challenging environments throughout the ages.

Cyclorana platycephala is a frog that is found in Australia. Like all frogs, it needs to keep its skin moist. During periods of drought it digs a chamber in the ground and lines it with mucous, which hardens and seals the chamber from water loss. The frog settles into the chamber, its metabolism slows down, and it becomes inactive. The frog can survive in this state for up to five years. Describe how this trait will determine the types of biome that the frog might live in.
These traits will make the frog live in harsh conditions in its different biomes.
The species, Cyclorana platycephala, has moist skin to undergo cutaneous respiration. It can dig underground chambers and line the chamber with mucous to avoid water loss. This is important to avoid severe conditions of drought when water is scarce.

A geologist sees this folded rock when studying in the field. he is drawn to the sample that is labeled a. he determines this formation was caused by compression. what type of landform did he find at label a? anticline syncline plateau fault-block mountain
An anticline is a structural trap with an arch-like structure that typically forms as a result of compressional stress. In an anticline, the younger rocks are created on the outside while the older rocks are found inside.
What is meant by Anticline? A structural trap called an anticline is created when rock layers are folded into the shape of an arch. In an anticlinal trap, the rock layers were initially horizontally stacked until earth movement caused them to fold into an arch-like structure known as an anticline. Examples include the Purcell Anticlinorium, which dates from the Late Jurassic to Early Cretaceous and is located in British Columbia, the Blue Ridge Anticlinorium, which is located in the Appalachians in northern Virginia and Maryland, and the Nittany Valley in central Pennsylvania.Since these are the structures in which the oil and natural gas are confined, these anticlines are very significant in the study of geology.

how does the eukaryotic ribosomal small subunit recognize the start codon on the mrna?group of answer choicesit undergoes a conformational charge that recruits other proteins when it hydrogens bonds to the correct tri-nucleotide sequence.it binds an met-trna to the first aug codon after the kozak sequence.it wraps the mrna strand to bring initiation enhancer proteins into the vicinity of the start codon.it binds an met-trna to the first aug codon it encounters.it performs an atp hydrolysis within the small subunit once it encounters a met-trna already bound to the aug.
The statement "it binds an met-trna to the first AUG codon after the kozak sequence." is the correct answer to how eukaryotic ribosomal small subunit recognize the start codon on the mrna.
First option: This choice is incorrect since amino acids are connected to their associated tRNAs by activating ATP, a process known as aminoacylation of tRNA.
Option 2: This choice is appropriate. Once the tRNA is charged, mRNA attaches a met- tRNA to the first AUG codon following the kozak sequence.
Option three: This choice is incorrect. While recognizing the start codon on the mRNA, there is no conformational change in the tiny unit of the ribosome.
Option four: This choice is incorrect. The mRNA isn't wrapped by ribosomes. Instead, along the mRNA, ribosomes migrate from codon to codon.
Option 5: This choice is incorrect. The initial AUG codon, but before the kozak region, is where it binds a Met-tRNA.
