The process through which water migrates from the roots to the leaves of plants is known as Transpiration pull. It is a type of force that supports the withdrawal of water upward from the region of roots to the leaves.
Which vascular tissue is responsible for this water movement?The vascular tissue which is responsible for this water movement is known as the Xylem. The basic function of this vascular tissue is to facilitate the transport of water from roots to the stem and leaves.
This process of transport of water is initiated with the soil. The roots capture this water from soil with the help of root hairs which are then spread out throughout the different parts of the plant.
Therefore, the process of water movement from the roots to the leaves of plants is well-described above.

Robinson illustrates how she and her team are using corals to learn more about the ocean’s composition long ago. Briefly summarize what Robinson details about ancient ocean feedbacks.
Answer:
Robinson explains how she uses layers in fossilized corals to understand what the environment was like overtime. By finding out what mainly makes up each layer and finding out roughly how old each layer is, she can begin to understand what the chemical composition and climate was like when the coral pieces were alive
Which type of mutation adds one or more base pairs?
Answer:
Insertions
Explanation:
Because they are mutations that use extra base pairs and insert them into a new place for the DNA, when a section of DNA is lost, A insertion fills it in.
6. Why is water useful to cells?
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
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.

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?
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
A cell and it's environment have the same amount of dissolved solute. Both solutions are hypertonic
True
False

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?
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.

actually environmental science own words please need it now.
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.

how come human populations differ from other animal populations
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.
