A student performs an experiment to study the transport of water in and out of cells. He uses clear, semi-permeable plastic bags to represent the cell membrane. The student places three plastic bags of the same size, each containing a 1% concentration sucrose solution, into three different beakers. One beaker contains distilled water, another beaker contains a 3% concentration sucrose solution, and the third beaker contains a 1% concentratIon sucrose solution. The diagram shows the students experimental setup, the plastic bag before it is placed in the beakers, and the appearance of the bags after an hour in each solution. Which statement provides a conclusion about the transport of water in and out of cells based on the results of the students experiment?
Answers
Answer:
B
Explanation:
A. Water moves freely both inside and outside the cell independent of the solute concentration.
B. Water movement into the cell is dependent on the percent concentration of solutes both inside and outside the cell.
C. Water transports solutes out of the cell to balance the percent concentration of solutes both inside and outside the cell.
D. Water moves into the cell solutes move out of the cell to ensure their concentration is balanced both inside and outside the cell.
The correct statement that provides a conclusion about the transport of water in and out of the cells is that water movement into the cell is dependent on the percent concentration of solutes both inside and outside the cell.
Water molecules will always move from the region of higher water potential to the region of lower water potential. The more the solute concentration of a solution, the lower the water potential compared to a solution with a lower solute concentration.
Hence, water will move from the beaker containing distilled water into the plastic bag containing a 1% sucrose solution until an equilibrium is established - the solution in the beaker is hypotonic to the one in the bag.
On the contrary, water will move from the bag containing 1% sucrose solution into the beaker containing 3% sucrose solution until there is no longer any net movement of water - the solution in the beaker is hypertonic to the one in the bag.
There will not be any movement of water from the bag to the beaker containing 1% sucrose because both solutions are of the same concentration, that is, isotonic.
The correct option is B

Shahzadi is looking at a cell with an electron microscope. She estimates that the cell is 2 x 10-5 metres long. What is this number fully written
out?
Answers
The length of the cell when the number is fully written is twenty millionth meters long.
Given that the length of the cell is 2 x 10⁻⁵ meters long.
1 millionth = 0.000001 = 10⁻⁶
The length of the cell = 2 x 10⁻⁵ meters = 20 * 10⁻⁶ meters
Therefore the length of the cell when the number is fully written is twenty millionth meters long.

Answers
Answer:
G1 is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. In G1, cells accomplish most of their growth; they get bigger in size and make proteins and organelles needed for normal functions of DNA synthesis. Here, proteins and RNAs are synthesized, and, more especially the centromere and the other components of the centrosomes are made.

Cells have genes that affect cell division. These genes may be damaged by
environmental factors such as radiation, smoking, and viral infections. Oncogenes
stimulate rapid cell division and are normally turned off in adult organisms. Tumor
suppressor genes prevent continuous cell division and are normally turned on in
adult organisms. One of these tumor suppressor genes, called p53, can be turned off
by the effects of smoking tobacco. Based on the above information, what is the most likely result of turning off p53?
A Lungs become black from smoking
B Cells undergo uncontrolled division
C White blood cells are unable to stop infections
D. DNA chains are broken and form more chromosomes
Answers
Answer:
B.
Explanation:
A tumor is essentially when damaged cells continue multiplying. So by smoking your risking both damaging your cells and turning of the p53 gene.
can i have brainliest?
The most likely result of turning off p53 is cells undergo uncontrolled division. Hence option B is correct.
What are genes?Genes are defined as the fundamental genetic component transferred from parent to child. Genes are composed of DNA sequences and are organized sequentially at specified sites on chromosomes in the cell nucleus. The foundation of the body is made up of cells. Your body is made up of billions of interconnected cells in every part. Chromosomes are the units on which genes are organized.
Diseases like cancer can result from an alteration in the cell cycle's regular regulation. When the cell cycle is out of balance, cells have the potential to randomly divide and accumulate genetic errors that can cause a malignant tumor.
Thus, the most likely result of turning off p53 is cells undergo uncontrolled division. Hence option B is correct.

how come human populations differ from other animal populations
Answers
Answer:
Animal species come in many shapes and sizes, as do the individuals and populations that make up each species. To us, humans might seem to show particularly high levels of morphological variation, but perhaps this perception is simply based on enhanced recognition of individual conspecifics relative to individual heterospecifics. We here more objectively ask how humans compare to other animals ...
Explanation:
With in population, humans show low levels body height variation in comparison to variation observed in other animal population.
Similarly, human population does not show distinctive levels of body mass variation.
What are the importance of studying human population?The study of population helps us to understand the process that influence the size, growth, characteristics, and distribution.
Population studies highlight these problems for society, administrators, political System, economic Planning
The most important terminology which is immensely studied called demography where the study of human population is extremely essential to determine the age, composition.
It is essential to study in every country by analyzing patterns of life expectancy and accurately predict the future.
Demography is important to study, as it characterize the nature population changes over time, such as the aging population
Hence, humans population show low levels body height variation in comparison to variation observed in other animal population.

How does the word mutualism relate to the world we live in? (biology)
Answers
Mutualism plays a key part in ecology. For example, mutualistic interactions are vital for terrestrial ecosystem function as more than 48% of land plants rely on mycorrhizal relationships with fungi to provide them with inorganic compounds and trace elements. As another example, the estimate of tropical forest trees with seed dispersal mutualisms with animals ranges from 70–90%. In addition, mutualism is thought to have driven the evolution of much of the biological diversity we see, such as flower forms (important for pollination mutualisms) and co-evolution between groups of species.However, mutualism has historically received less attention than other interactions such as predation and parasitism.
