How does osmosis of water occur across the cell membrane?Plz help I need it ASAP
Answer:
In osmosis, molecules cross the cell's plasma membrane to achieve equilibrium.
Explanation:
A bilipid layer called a plasma membrane typically surrounds cells. Here, lipid molecules are arranged tail-to-tail, with their heads facing outwards. The heads of the lipids, are water soluble, while the tails are insoluble. Proteins and cholesterol also help maintain membrane fluidity.
With the use of its transport proteins, pores and gated channels, embedded among the lipids the membrane maintains its concentration of substances through selective permeability.
Simple diffusion occurs in cells through plasma membranes as a means of passive transport. In osmosis, molecules of water move across the membrane, down their concentration gradient- i.e. they try to balance their concentration or number of water particles.
The water particles move from regions of high concentration to regions of low water concentration. Typically these 'destinations' or regions have large amounts of solute which contributes to the formation of this gradient.

geosphere or the geological carbon cycle).
dosent have to be a long answer! thank you
Answer:
Plankton use carbon to make carbonate (CO3) shells in the ocean. The shells sink and accumulate into layers of sediments and eventually rocks. Rocks are pushed deep into the earth and melt at subduction zones, dissolving the carbon. Volcanic eruptions release carbon dioxide into the atmosphere.
Explanation:
What is the name of the process that plants use to remove carbon from the atmosphere?
Photosynthesis
Because they use carbon in photosynthesis and hence they need it. So, they take it from atmosphere.
6CO2 + 6H2O → C6H12O6 + 6O2
Cells spend very little of their life performing mitosis. Most of a cell’s life cycle is spent in interphase. Interphase is made up of the first growth phase, the synthesis phase, and the second growth phase. The synthesis phase is characterized by -
The division of cytoplasm
Cell division
Replication of mitochondria and other organelles
DNA replication
Answer:
DNA replication
Explanation:
Synthesis is the stage characterized by DNA replication. It is after the G1 phase
Most of the cell's time is spent in the interphase. The first growth phase comes first, then the synthesis phase, and finally the second growth phase. In the synthesis phase, DNA replication occurs. So the last option is correct.
What is interphase in a cell cycle?
The interphase is the preparatory phase of the cell before going into the division phase (M phase). The first phase is the G1 phase, or first growth phase, in which the cell grows in size. Then the cell enters the synthesis phase, or S phase, where the cell's genetic material, which is DNA, is replicated.
A single DNA molecule duplicates itself, but the two DNA molecules are linked by a single centromere. In synthesis phase the centrosome replicates too, making two centrosomes. Then the cell enters the second growth phase, or G2 phase. Here the cell again grows for the division.
Hence, in the synthesis phase, DNA replication occurs. The last one is correct.

Do you now notice any signs of growth? In which part of the ginger piece do you
notice growth occurs?
is there a picture near the question?
In ginger, growth can be seen in the rhizome, it is a modified root. The rhizome grows the plant.
What is growth?Growth is the constant expansion of an organism's size through time. It could also be described as one of a living thing's traits. "Biological growth" in biology refers to development that occurs throughout time. Throughout their lives, living creatures frequently expand. But it is a process that unfolds gradually and on a regular basis.
Typically, growth starts when a single cell is present. This cell may divide and enlarge in a particular area, as in plants, or it may diversify and enlarge over the entire organism, as in mammals.
The environment and internal elements have a large role in determining how rapidly or slowly an organism will grow. These variables have undergone centuries of change, changing how living things behave. Thus, growth can be in rhizomes in ginger.

The process of meiosis does all of the following except:
Goes through two rounds of division.
Forms sex cells or spores.
Results in four unique haploid cells.
Produces two genetically identical cells.
Answer:
The last one does not happen meiosis create four genetically different haploid cells
Meiosis, on the other hand, creates four distinct daughter cells, each of which has half as many chromosomes as the parent cell. Thus, option D is correct.
What are the advantages of meiosis?Meiosis is crucial for three reasons: it promotes genetic diversity, sexual reproduction of diploid species, and the correction of genetic flaws.
A parent cell undergoes mitosis, which creates two identical daughter cells with the same number of chromosomes.
Genotypic diversity is produced, and appropriate homologous chromosomal segregation is ensured via meiotic crossing over.
Despite these functions, very little is known about the genetic and population genetic mechanisms that resulted in the evolution of species-specific variations in recombination rates.
Therefore, process of meiosis produces two genetically identical cells.

animals obtain glucose from ?
Answer:
[tex]\boxed {\boxed {\sf Eat \ other \ plants \ and \ animals}}[/tex]
Explanation:
Plants, algae, and certain bacteria can photosynthesize and make their own food by converting carbon dioxide, water, and sunlight to glucose and oxygen.
Animals cannot undergo this process and produce their own food, so they have to eat food to obtain glucose.
Animals get glucose and energy by consuming plants or other animals.
Animals obtain glucose from the food they consume.
How do animals obtain glucose?When animals eat carbohydrates, such as sugars and starches, their digestive system breaks them down into simpler molecules, including glucose.
Glucose is then absorbed into the bloodstream and transported to cells throughout the body, where it is used as a source of energy for various metabolic processes.
In addition to carbohydrates, animals can also obtain glucose from other nutrients like proteins and fats through processes like gluconeogenesis, where these molecules are converted into glucose when needed by the body.

The time it takes for an animal to metabolize a drug to a non-detectable levels could be ____ than that of the withdrawal period 
A:Longer
B:Shorter
C:Same time
The time it takes for an animal to metabolize a drug to a non-detectable levels could belongerthan that of the withdrawal period. Hence the correct option is A.
The metabolism of a drug refers to the process by which the body breaks down and eliminates the drug from the system. The withdrawal period is the time required after administering a drug during which the animal must not be slaughtered for human consumption to ensure that no residues of the drug are present in the edible tissues.
There are several factors that can influence the metabolism of a drug in animals, such as the drug's chemical properties, the animal's species, age, health status, and metabolic rate. Some drugs may be metabolized relatively quickly, while others may take longer to be completely eliminated from the system.
Hence the correct option is A.
