In the given case, cell A is placed in 2 % solution of glucose and cell B is placed in 5 % glucose solution. Both the solutions are hypotonic, and when a cell is placed in a hypotonic solution, then the greatest concentration of water will be outside of the cell. Therefore, water will enter the cell and occupies the central vacuole.
However, cell B is placed in a more concentrated solution, so it will swell less in comparison to cell A, which is placed in a less concentrated solution. Hence, the correct answer is option A, that is, Cell A will swell more than Cell B.
The correct option is A.
Which is cell A will swell more than cell B.
Explanation:As the cells have same concentrations.So when they put in different solutions, Cells A in 2% glucose will lose less water due to osmosis than cells B which are in 5% glucose solution.Hence cells A will be more swell than cells B.Biology. Carbohydrates.

Eukaryotic cells are much larger and have more specialized functions than prokaryotic cells because they contain___________, which take up space and carry out specialized activities.
Final answer:
Eukaryotic cells contain organelles that are essential for various specialized functions, unlike prokaryotic cells which lack these structures.
Explanation:
Eukaryotic cells are much larger and have more specialized functions than prokaryotic cells because they contain organelles, which take up space and carry out specialized activities. While prokaryotic cells lack these membrane-bound structures, eukaryotic cells boast an assortment of organelles such as the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus among others. Each of these organelles plays a critical role in the cell's life, with functions ranging from genetic material storage and energy production to protein synthesis and waste processing.

Which fator can decrease the rate for chemical reactions . A. Low activation energy ,B.hight pressure ,C.low temperature.D.high concentration of reactants
Low temperature will slow the chemical reaction.
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei and can often be described by a chemical equation.
C- Low temperature
When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction.

The changes in biodiversity can be influenced both, by the humans and their activity, and the natural events that are taking place on our planet. Throughout the geologic history, lots of natural events. like asteroid collisions, super-volcano eruptions, changes in the composition of the atmosphere etc, have resulted in the dying out of millions of species, and even though this process of natural selection continues, it is not the dominant cause anymore. Nowadays, the biggest cause of loss and changes of biodiversity is the human activity. Lots of living organism have lost their habitats and food sources and went extinct because of the human activity, and also some species have died out or are on the verge of extinction because of the introduction of non-native species to certain places, and that has been devastating to the local wildlife.

The map shows the distribution of wild boars in the United States. Wild boars are an invasive species to the United States. Which of these facts about wild boars is best supported by the evidence provided? Wild boars were brought to the United States by humans. Wild boars have quickly spread through the United States. Wild boars have established successfully in areas with warm climates. Wild boars have a high reproductive rate and no natural predators.
I'm pretty sure it's D, I could be wrong but it seems like it's the most correct answer.
Answer:
Option D,
Explanation:
It is given that wild boars are invasive species which means they are not native to the ecosytems of united states and since they are invasive they are also harming the native plants and animals life.
An invasive species becomes disastrous because there in no known way of controlling it.
Wild boars being invasive spread to different locations of USA , thus they must be having a high reproduction rate . Also, they , they might not be having any natural predators , therefore they have grown uncontrollably
Hence, option D is correct

What list describes the diet of an omnivore? Mice and rabbits Rabbits and insects Fish and insects Fish and berries
The correct answer is D. Fish and berries.
Explanation
Omnivorous is a term of Latin origin that means eating everything. At present, the term is used to refer to all species of animals (including humans) that eat different foods, that is, omnivorous animals, unlike carnivores (which feed exclusively on meat) and herbivores (which it feeds exclusively on plants) eat herbs, fruits and meat. Therefore, it can be affirmed that the diet of an omnivore is composed of fish and berries. So, the correct answer is D. Fish and berries.

are organisms that contain more than one cell with membrane-bound organelles and a nucleus.
eukaryotes are organisms that contain more than one cell with membrane-bound organelles and a nucleus.
Eukaryotes are organisms with cells that contain a membrane-bound nucleus and organelles. They can be unicellular or multicellular and are distinct from prokaryotes, which lack a nucleus and membrane-bound organelles. Eukaryotic cells are typically larger and more complex than prokaryotic cells.
Organisms that contain more than one cell with membrane-bound organelles and a nucleus are known as eukaryotes. These organisms can be made up of a single cell or can be multicellular. They are characterized by having a nucleus that contains the organism's genetic material and is surrounded by a complex nuclear membrane. Additionally, eukaryotic cells contain several other membrane-bound organelles, such as mitochondria, endoplasmic reticulum, and Golgi apparatus, which perform specific functions necessary for the cell's survival and operation.
Eukaryotic organisms include a vast array of life forms including protozoa, fungi, plants, and animals. A significant difference between eukaryotes and prokaryotic cells, such as bacteria, is the presence of a nucleus and other membrane-bound organelles in eukaryotes, which are not found in prokaryotes. Eukaryotic cells are typically larger than prokaryotic cells and are the building blocks of complex organisms.

The development of pesticide resistance in crop pests is an example of?
Pesticide resistance in crop pests is an example of natural selection. Individuals with gene versions that confer pesticide resistance are more likely to survive and reproduce, leading to the increase of pesticide resistance in the pest population over time.
Explanation:Pesticide resistance in crop pests is an example of natural selection. When pesticides are repeatedly applied to a pest population, individuals with gene versions that confer pesticide resistance are more likely to survive and reproduce. As a result,
pesticide resistance becomes more common in the population over time. This phenomenon is observed in over 400 insects and mite pests and more than 70 fungal pathogens that have become resistant to one or more pesticides.
what is codon. what does it do
A codon is basically a "word" in the genetic code.
Let's start at the base. A base is the smallest unit of information in genetics. It is a chemical represented by either A, T , C, G or U.
These genetic "letters" are combined into "words" which are called codons. What is useful is that each codon is only made of 3 bases. You'll have CCT, GAT, TTA etc. So what do these words represent? Well they can be instructions, like START or STOP, but usually they represent an amino acid, the LEGO building blocks of proteins. There are around 20 AAs but a bit of maths tells us we have a lot more codon combinations than AAs. This means we have some synonyms where several codons can represent one AA.
To take the analogy further, the codons combine into "sentences" and then "chapters". The chapters are a gene, usually instructions for a complete protein, but some of the sentences are useless and will be ignored when translating into a protein.
Then we have the "Book" which is the chromosome. The reason I like to think of it as a book is that at this point it is a contained unit, a massive molecule. You can separate up your books and even lend one to a friend, but you can't do that with a chapter unless you destroy the book.
Finally you have you "library" or genome. It's not a big collection, 46 books in total, and in fact you have 2 copies of each. It's like inheriting 2 sets of encyclopaedias from your parents. They both have the same information, it is just explained in different ways.
And there is my book analogy of genetics. It's not perfect but works when used on small children.
By what process are animal wastes and dead organisms converted to other nitrogen containing compounds ?
Answer:
Decomposing
Explanation:
When bacteria starts to break down the dead matter from organisms, this is called decomposing
Animal wastes and dead organisms are converted to other nitrogen-containing compounds through ammonification, nitrification, and denitrification, involving various microorganisms that complete the nitrogen cycle.
Animal wastes and dead organisms are converted to other nitrogen-containing compounds through a multi-step process involving different types of microorganisms. First, ammonification occurs, where bacteria and fungi convert organic nitrogen into ammonia (NH3). This ammonia then undergoes nitrification, carried out by bacteria such as Nitrosomonas, turning ammonia into nitrites (NO2) and then into nitrates (NO3). Finally, through the process of denitrification, bacteria like Pseudomonas and Clostridium convert nitrates back into gaseous nitrogen (N2), which re-enters the atmosphere, completing the nitrogen cycle.
A scientist uses material in her lab to separate dna fragments by size what process is she using
She is using gel electrophoresis, where a DNA sample with DNA molecules of varying length are ran through an agarose gel to separate them into bands by size from longest at the top to shortest at the bottom.
Answer: Gel electrophoresis
Explanation:
Gel electrophoresis is a technique that is used to separate DNA fragments based on their size.In this technique, DNA samples are loaded into the wells at one end of a gel, and then an electric current is applied. DNA fragments being negatively charged move towards the positive electrode. Since, all DNA fragments have the same amount of charge per mass, small fragments move through the gel at a faster rate than large ones.In this way the fragments get separated by size.
