In which situation would water enter a cell through osmosis?
A.The cell is 20% water, and the cell's environment is 80% water,
B.The cell is 50% water, and the cell's environment is 50% water,
C.The cell is 60% water, and the cell's environment is 40% water.
D.The cell is 80% water, and the cell's environment is 20% water.
Answers
Answer:
A
Explanation:
Water enters osmosis when the cell's water is lower than its environment's water. This is known as Hypertonic. B is an equalibrium so nothing special happens there, and C and D are examples of potential bursting of the cell from too much water, known as Hypotonic, so in process of elemination, A would be the answer. Another way of telling that C and D aren't the answer is that if they were really true, both of them would be correct, and there can't be two correct answers.
Water would enter the cell if the cell is 20% water, and the cell's environment is 80% water (Option A).
Osmosis refers to the process of movement of a solvent (e.g., water) from a solution of lower concentration to a solution of higher concentration through a semi-permeable membrane.The osmosis movement tends to balance the final concentrations of solute on the two sides of the membrane.This process (osmosis) is called passive transport because it does not require energy to move water molecules through biological membranes.In conclusion, water would enter the cell if the cell is 20% water, and the cell's environment is 80% water (Option A).

The answer is C
Explanation:
I was correct at first but then chanaged my answer when someone said it was a :(
A few of the positive particles aimed at a gold foil seemed to bounce back off of the thin metallic foil. Therefore, option (1) is correct.
The gold foil or Rutherford scattering experiment showed that the atom has a small, compact, positively charged nucleus. The gold foil deflected few alpha particles, indicating that the atom is primarily empty space. A small percentage of particles deflected or bounced back, revealing a concentrated positive charge in a limited region of the atom.
This led to Ernest Rutherford's atomic model, often known as the planetary model, where the atom has a tiny, positively charged nucleus at the centre and mostly empty space where electrons orbit it. Therefore, option (1) is correct.

Answers
Answer:
these continents were joined as a single landmass
Explanation:
Alfred Wegener proposed the 'Continental Drift Hypothesis' which stated continents were joined into a single great landmass called Pangaea. Pangea was a supercontinent that was assembled during the late Paleozoic and early Mesozoic eras, from about 330 to 200 million years ago. During the early Mesozoic, Pangea began to separate into continents observed today. It is for that reason that the same fossils can be found in very different geographic-climatic regions, evidencing that in the past continents were joined into larger landmasses.

cells. During sexual reproduction, the traits that are determined by the genes on these chromosomes are passed on from parents to offspring.
Answers
Answer:
During metaphase 1, the chromosomes line up in the middle of the cell. The way the chromosomes line up is random, or independent. This independent alignment results in different possible arrangements or assortments of chromosomes during metaphase. This in turn results in different sets of chromosomes in daughter cells. During sexual reproduction, the traits that are determined by the genes on these chromosomes are passed on from parents to offspring.
Explanation:
In metaphase, the typical chromosome is formed by two chromatids joined by a centromere. Each chromatid is composed of a sequence of chromatin ringlets domains. During metaphase I, fibers of the spindle apparatus capture chromosomes and take them toward the center of the cell, to the metaphase plate. Each chromosome of the pair joins with a microtubule of only one of the spindle poles, so the two equivalent chromosomes join the fibers of opposites poles.
The homologous pairs of chromosomes get aligned in the metaphase plate for their posterior separation in anaphase I. When they align in the center of the cell, their orientation is random.

Why do you think it is important for a cell to grow before it replicates its DNA? Be as specific as you can in your answer
Answers
Answer:
Basically, every time a cell undergoes mitosis (one kind of cell division), various enzymes work to split each DNA strand in half, and then replace the missing half on the separated strands with corresponding nucleotides, leaving you with two identical strands. When the entirety of a cell's genome is copied (along with all the organelles), the cell can split into two daughter cells.
Imagine slicing yourself down the middle and splitting yourself in half, and then using each half of you as a template to recreate the other half.
That's the biology behind it, but the bottom line is that DNA is replicated in order to reproduce itself.
Explanation:
It is important for a cell to grow before it replicates its DNA so - each daughter cell gets the same number of identical DNA.
DNA replication needs to occur because existing cells divide to produce new cells.
Each cell needs a full instruction manual to operate properly.So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions.This way each cell gets the same instructions to perform the cellular functions.Thus, it is important for a cell to grow before it replicates its DNA so - each daughter cell gets the same number of identical DNA.

A spontaneous change in DNA that may lead to cellular malfunction is the most complete and accurate description of mutation.
In genetics, a spontaneous and unpredictable variation in the sequence of genes that make up the DNA of a living being that introduces specific changes is called a mutation.
This alteration, which can be hereditary, implies a modification of its characteristics.
These types of changes occur spontaneously and naturally, product of errors in the replication of the genome during the phases of cell replication.
From a mutation, the living being can develop different diseases, manifest changes in its organism or hereditary defects.
Despite of this, mutations are key to sustaining high genetic variability, promoting adaptation and evolution (even creating new species in the long run).
Therefore, we can conclude that a spontaneous change in DNA that may lead to cellular malfunction is the most complete and accurate description of mutation.

Photosynthesis removes carbon dioxide from the atmosphere and generates oxygen, while cellular respiration releases carbon dioxide into the atmosphere and consumes oxygen.
Photosynthesis refers to the series of metabolic reactions by which plants use carbon dioxide from the atmosphere and sunlight to produce oxygen and simple carbohydrates (i.e., sugars).
Conversely, cellular respiration is a series of reactions by which aerobic cells use oxygen from the atmosphere and the energy stored in the chemical bonds of foods to produce carbon dioxide and ATP.
Photosynthesis reactions can be divided into light-dependent relations and light-independent reactions.
Moreover, cellular respiration has three stages: glycolysis, the acid citric cycle and oxidative phosphorylation.
In conclusion, photosynthesis removes carbon dioxide from the atmosphere and generates oxygen, while cellular respiration releases carbon dioxide into the atmosphere and consumes oxygen.

His movement stopped.
His acceleration is zero.
His time was constant.
His acceleration was positive.
Answers
Considering the definition of acceleration, since the speed does not change, his acceleration is zero.
Definition of accelerationA body has acceleration when its speed varies over time, either in magnitude or in direction.
In other words, the acceleration of a body is a physical magnitude that indicates the variation in speed experienced by a body in its displacement as a function of the time spent on it.
Therefore, a moving body is changing acceleration as its speed changes. As speed is a magnitude that considers the speed of a mobile and its direction, the changes that occur in speed will be due to variations in speed and/or direction.
