What are codons and anticodons?
Answer:
A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. An anticodon is a trinucleotide sequence complementary to that of a corresponding codon in a messenger RNA (mRNA) sequence. An anticodon is found at one end of a transfer RNA (tRNA) moleculeExplanation:
As the average kinetic energy of the particles in a gas increases, which of the following
occurs? (1 point)
The temperature of the gas increases.
The temperature of the gas decreases.
The number of particles increases.
The number of particles decreases.
Answer:
Amontons’s law. If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure

It is important to survival that both unicellular and multicellular organisms are able to maintain homeostasis. Which is not example of organisms maintain homeostasis?
A.cells always stay the same.
B.cell division allows or organisms to grow and repair damaged parts.
C.food is made during photosynthesis, and energy is produced from during respiration.
D.materials move into and out of the cells though the cell membrane.
Answer:
A.cells always stay the same.
Explanation:
Homeostasis is the ability of an organism to maintain a stable internal state despite changes in external conditions. The process of homeostasis is important to the survival of both unicellular and multicellular organisms, as mentioned in this question.
Examples of homeostatic process undergone by organisms include:
- Cell division, which allows organisms to grow and repair their damaged parts.
- Making of food during photosynthesis, and production of energy during cellular respiration. This two processes are necessary for the survival of organisms as one produces food and the other synthesizes energy.
- Movement of materials into and out of the cells though the cell membrane, which is required to bring in needed substances and remove unwanted ones.
However, a cell staying the same does not depict any HOMEOSTATIC PROCESS.

There was a nearly intact fossil of a hadrosaur called Dakota. How did this find change our knowledge of the hadrosaur? List three specific ways.
Answer: Environment, skin coating, and perhaps seasonal migration.
Explanation: The hadrosaur has become an unmistakable species due to its unusual bill, and bipedal legs. However this new fossil could change many studies. First off, environmental hazards. Due to the amount of carnivorous fossils found in the Dakota area, finding a nearly intact fossil of any sort should be quite impossible. This brings paleontologists to believe hadrosaurs may have had some sort of defense against predators, which brings us to skin coating. To be found in such an arctic area must have meant it would be difficult for anything herbivorous to live in the area, unless feathers, or fur was involved. This could change every theory about the so called scaly beasts we refer to as dinosaurs. This brings us to our final topic, migration. Every winter if you were to go outside, it would be highly unlikely to hear birds. This is known as migration, a period when certain animals of multiple species, typically birds, move to warmer areas for the winter. Consider if the birds descending from dinosaurs theory was correct. This could in fact be how birds somehow get this preconceived notion to migrate. This, just as wild dogs are naturally aggressive, could be instinct.

How do human beings negatively affect the carbon cycle?
Human beings burn fossil fuels, which contribute carbon dioxide to the atmosphere.
Human beings conserve resources, which decrease resources for the carbon cycle.
Human beings mine resources, which increases the amount of oxygen available to the carbon cycle.
Human beings use carbon-based pencils, which decreases the amount of carbon dioxide in the atmosphere.
Eww
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. ... This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.

If an individual has the genotype Bb, what alleles can it pass on to its
offspring?
A. Only B
B. Neither B norb
C. Either B or b
D. Only b
If a person possesses the genotype Bb, either the B or the b alleles can be passed on to their progeny. So, the correct option is C.
What is Genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries inside a specific gene or genetic region are also referred to as the genotype.
The term "genotype" relates to an organism's whole gene pool, or, in other words, the genetic make-up of that creature. The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning. Symbols can be used to symbolise it. For illustration, BB, Bb, and bb could be used to denote a certain gene variant.
If a person has the genotype Bb, as in the example above, then either the B or the b alleles can indeed be passed on to their progeny.
Therefore, the correct option is C.

HELP!What are the roles of and what happens to chromosomes, centrioles, centromeres, spindle fibers, nucleus and cell membrane during mitosis.
Answer:
Perhaps the most amazing thing about mitosis is its precision, a feature that has intrigued biologists since Walther Flemming first described chromosomes in the late 1800s (Paweletz, 2001). Although Flemming was able to correctly deduce the sequence of events in mitosis, this sequence could not be experimentally verified for several decades, until advances in light microscopy made it possible to observe chromosome movements in living cells. Researchers now know that mitosis is a highly regulated process involving hundreds of different cellular proteins. The dynamic nature of mitosis is best appreciated when this process is viewed in living cells.

11. Tom broke his leg. He was in a cast for six weeks. After his cast was
removed he had a hard time walking - WHY? *
Answer:
what-
Explanation:
Answer:
Well, the reason is because those muscles that he was once using every day, were suddenly on break and were not being used for the entire 6 weeks. Leading him to having some trouble walking.
Explanation:
When you don't use your muscles, they start to kind of chill out and get weaker in this case. So when you break your leg, and the doctor tells you not to put pressure on it, it is so that the bone can heal. But while your bone heals, the muscles in your leg are not able to move or do very much of anything because you can't put any pressure on them. So that is why when you take the cast off, you have to ease back into the regular motion in your leg that you had before.
Hope this helps!

Discuss some of the advantages to having a cycle that partially replenishes itself. In the Calvin cycle, what would happen to the cycle if there was no carbon dioxide available?
Answer:
The carbon atoms used to build carbohydrate molecules come from carbon dioxide, the gas that we exhale with each breath.
Explanation:
Dark reactions are also referred as "light independent reactions" (since they can occur during day or night) or as "carbon-fixation" (since carbon dioxide is taken from the air and carbon is affixed to compounds in the plant) or as the Calvin Cycle (named for the person who discovered it).

Fully explain how cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy.
Cellular respiration is a metabolic process called cellular respiration that converts glucose to ATP.
What is cellular respiration?Cellular respiration has the processes: Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the phases of cellular respiration.
A glucose molecule gradually decomposes into carbon dioxide and water during cellular respiration. In the process of transforming glucose, some ATP is directly created.
But far more ATP is later created through a procedure known as oxidative phosphorylation. The electron transport chain, a collection of proteins enmeshed in the inner membrane of the mitochondrion, is what drives oxidative phosphorylation.
Therefore, Cellular respiration is a metabolic procedure by which glucose is changed into ATP.

why is active transport needed to take mineral ions into the cytoplasm of the root hair cell?
Answer: In plants, they need to move mineral ions from the soil into the roots. Mineral ions are more concentrated in the cytoplasm of plant cells than in soil water or dillute.
Explanation:
Minerals cannot be soaked up through osmosis since it only involves the movement of water. Because the minerals are in such low concentration, they cannot be absorbed through diffusion. Active transportation is used instead.
What is active transport?Active transport refers to the transport of molecules or ions into or out of a cell via the cell membrane, from a low concentration region to a high concentration region.
The particles use the energy released during respiration to move against the concentration gradient.
Active transport is defined as the movement of molecules against a gradient from a region of lower concentration to a region of higher concentration.
Active transport in plant root hairs allows plants to absorb mineral ions, which are required for healthy growth, even though the concentration of minerals in the soil is usually lower than in the root hair.
Thus, active transport is needed to take mineral ions into the cytoplasm of the root hair cell, as there is a need to move the minerals from the region of lower to higher concentration.

Experiment 5
Lisa is working on a science project. Her task is to answer the question:
"Does Rogooti (which is a commercial hair product) affect the speed of hair growth"? Her
family is willing to volunteer for the experiment.
1. Identify the hypothesis in this experiment.
2. State a conclusion to support your hypothesis. 3. State a conclusion that refutes the hypothesis.
Answer:
Hypothesis: The commercial hair product Rogooti accelerates hair growth.Conclusion 1: Rogooti makes hair grow faster than it would normally do when using an ordinary product.Conclusion 2: Rogooti does not seem to have any effect on hair growth.Explanation:
A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact.
A hypothesis must express what is expected to occur comprehensively. There must be a logical relation between variables. It must be objective.
To answer the question, Lisa might propose the following hypothesis, which needs to be corroborated.
Hypothesis: The commercial hair product Rogooti accelerates hair growth.
Experiment: Her family is a volunteer for the experiment, so all of them will use an ordinary hair product for a month. Before and after this period they will take notes of how long their hair is before and after the first part of the experiment. After this, they will cut down their hair to the initial length, and they will start using Ragooti for another month. After this last one, they will measure hair length again. Finally, Lisa will compare the initial length with the one after the first month and after the second month to analyze how Rogooti affects the speed of hair growth.
Result 1: When comparing lengths, Lisa will see that the hair of all her family members grew longer during the second month.
Conclusion 1: Rogooti makes hair grow faster than it would normally do when using an ordinary product.
Result 2: When comparing lengths, Lisa will not see any significant difference in the hair growth of her family during the first and the second month.
Conclusion 2: Rogooti does not seem to have any effect on hair growth.
