a student is investigating cellular transport. what will most likely occur when the student places a cell that is 95% water inside of a solution that is 100% water?
Cellular transport refers to the flow of substances into or out of the cell across the cell membrane.
When the student places a cell that is 95% water inside of a solution that is 100% water, the cell will achieve net movement and if water continues to enter, it swells up and burst.
When a cell is placed in a hypotonic solution, water flows into the cells and the cell gains volume until it achieves equilibrium. But if water continues to flow in afterwards, it swells up and burst.Learn more about cellular transport: https://brainly.com/question/6949569

is the DNA in the form of chromatin or chromosomes when a cell finished cytokinesis
Answer:
Cell cycle consists of interphase and mitosis. During interphase there are 3 phases- G1, S and G2 phases. G1 is the resting phase after previous mitotic phase, S phase is DNA synthesis phase and G2 phase is again resting phase.
DNA synthesis occurs before mitotic phase which is the actual cell division phase and chromosomes are condensed during mitotic phase therefore it's in the chromatin form that DNA is synthesised.

Fraternal twins, while conceived at the same time, are not genetically identical.
Which statement best explains why these siblings are genetically different from each other
Answer:
Fraternal twins are also called dizygotic twins. And the difference between fraternal and identical twins is that fraternal twins derive from two different eggs. Fraternal twins may be the same gender, they may have many of the same characteristics, but also may be very different from each other and, in fact, share half of their genes just like their sisters and brothers. It's important to recognize that the difference between fraternal twins and monozygotic, or identical twins, is that monozygotic twins result from the fertilization of a single egg with a single sperm and then during the embryonic development, or during the cell splits, those massive eggs split into two individuals, which later develop into two offspring.

How is a red blood cell adapted to carry
oxygen and nutrients throughout the body? Explain
3.
What would happen to us if no platelets
are found within the blood again. Explain.
4. Give the general (collective) functions of the blood
Answer:1. White blood cells are part of the body's immune system. They help the body fight infection and other diseases.
2. Red blood cells have adaptations that make them suitable for this.
3. The blood would not clot in case of an injury.
4. Blood supplies essential substances and nutrients.
Explanation: 1. White blood cells are able to recognize viruses and/or infectious germs, which is how they fight off disease/sickness. It is also why we have vaccines. Vaccines put either dead or weakened parts of a germ into your body. Then, the white blood cells recognize it and fight it off the next time it enters your body.
2. They contain hemoglobin, a red protein that combines with oxygen. They have no nucleus so they can contain more of the hemoglobin. they are small and flexible so that they can fit through narrow blood vessels.
3. This will lead to excess blood loss and can even lead to the death.
4. Such as as sugar, oxygen, and hormones to our cells. It also carries waste away from the cells, this waste is eventually flushed out of the body in urine, feces, sweat, and lungs.

An inventor claims to have invented an artificial kidney for patients that need a kidney
transplant. Which of the following would be a reason that the scientific community might
reject this claim?
A. Previous investigations were unable to obtain the same results.
B. The inventor failed to present observations with data.
C. Investigations were performed in an unknown laboratory.
D. The device failed to follow law of conservation of mass
All of the given options could potentially be reasons why the scientific community might reject the inventor's claim, but the option that specifically relates to the principles of science is option D: the device failed to follow the law of conservation of mass.
What is an artificial kidney?In the case of an artificial kidney, the device is supposed to filter out waste products from the blood, which is then supposed to be removed from the system in a measurable form, such as through urine or dialysis fluid. If the device fails to remove the waste products from the blood, or if it makes them disappear without a measurable output, it would suggest that the device is not functioning as claimed and may not be effective in treating patients who need a kidney transplant. Therefore, the scientific community would likely reject the inventor's claim until there is evidence that the device follows the fundamental principles of science, such as the law of conservation of mass
Hence, the option that specifically relates to the principles of science is option D: the device failed to follow the law of conservation of mass.

Answer:
It is the iris that determines eye color.
Explanation:
A person's eye color results from pigmentation of a structure called the iris, which surrounds the black hole in the center of the eye, the pupil. It helps control how much light can enter the eye. The color of the iris can obviously range from blue, green, brown and I think grey too if fiction books can be trusted lol

Answer:
There are many different kinds of microscopes. A magnifying glass is a simple microscope. The term microscope commonly refers to a compound microscope. These Microsoft are called compound because they are made of several glass lenses in a tube. The total magnifying power of a microscope is the product of the magnifying power of the lens is in the ips and the magnifying power of the lens in the objective.. Most compound microscopes can magnify a specimen up to 400 times as real size. Microscope allow you to see fine details. Space is between objects that are closer together than 0.1 mm can be seen. The ability of a microscope to separate small distances is called resolving power. If the resolving power is not good the image will be blurred. When you look into the eye piece of microscope the circular area you see is the field of view when a ruler is placed across the opening of the stage the field of view can be measured in millimeters. Sharpening an image under high magnification used the Find adjustment knobs. The part of the microscope that holds the Microscope slide is called the stage.

why a genetic bottleneck can be an important evolutionary factor for a species
Answer:
Genetic drift decreases genetic diversity within a population.
Explanation:
Genetic drift decreases genetic diversity within a population. It is a change in allele frequencies due entirely to random chance and is more likely to affect smaller populations than large ones. Population bottlenecks can lead to genetic drift.

If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis
Answer:
3
Explanation:
If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis after 3 stages.
What is meiosis?
In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).
Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent). The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state.
Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.
Nearly every human cell contains 46 chromosomes, 23 of which come from one of our parents and 23 highly similar chromosomes from the other parent. The appropriate number of chromosomes in a cell is crucial.
Therefore, If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis after 3 stages.
