What is the water potential of a .20 M solution of sucrose in an open beaker at 23 degrees Celsius?
Answer:
-4.92 bars
Explanation:
The water potential of a solution is the sum of the pressure potential and the solute potential of the solution. This can be mathematically expressed as;
Фw = Фp + Фs, where Фw = water potential, Фp = pressure potential, and Фs = solute potential.
For a solution that is in an open beaker, the Фp = 0. hence
Фw = -Фs
Also,
Фs = iCRT, where i = number of particles the molecule will make in water (1 for sucrose), C = molar concentration, R = pressure constant (usually 0.0831 liter bar/mole K), and T = temperature (in kelvin).
In this case, i = 1, C = 0.20 M, R = 0.0831, T = 273+23
Фs = 1 x 0.20 x 0.0831 x 296 = 4.92 bars
Therefore,
Фw = -4.92 bars
The net force on an object is 80 N. The mass of the object is 40 kg.
What is the acceleration of the object?
I
Answer:
The acceleration of object is 2 m.s⁻².
Explanation:
Given data:
Force on object = 80N
Mass of object = 40 kg
Acceleration = ?
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m
Now we will put the values in formula.
a = 80 N/40 kg
a = 2 m.s⁻² (N = Kgm.s⁻² )
Be able to analyze data and make conclusions about the data

how can to plant cells from the same plant have different structures and functions
Answer:
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.

How does a cell of a unicellular organism differ from a cell of a multicellular organism
Answer:
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function
Explanation:
what is the role of coenyme a in the cell
The molecule known as coenzyme A plays a key role in cell metabolism by regulating the actions of nitric oxide. Coenzyme A sets into motion a process known as protein nitrosylation, which unleashes nitric oxide to alter the shape and function of proteins within cells to modify cell behavior.

Paleontologists discovered fish fossils in the arid deserts of western Egypt. What does the fossil evidence most likely indicate about this area's geologic past? A: The desert was once a vast ocean. B: A giant ocean wave carrying sea life crashed onto the desert.
C: Mountains in the region once provided water from snowmelt.
D: The area was moved from the ocean to the deserts by plate tectonics.
Answer:
The correct answer is option A: "The desert was once a vast ocean".
Explanation:
One of the most prominent fish fossils that were found in the arid deserts of western Egypt belong to the Giant Catfish named Qarmoutus hitanensis, that lived roughly 37 million years ago as it was scientifically determined. The presence of this and other related fossils indicate that the desert was once a vast ocean. Actually, the arid landscape of this zone has been named Wadi Al-Hitan (which means Valley of the Whales) in honor to its past.
In general, which factor is NOT critical when beginning an exercise program?
A. using appropriate protective equipment during exercise
B. finding friends who like to exercise the same way you do
C. seeing your doctor for a physical assessment prior to beginning exercise
D. choosing clothing that is designed to match your exercise program
Please select the best answer from the choices provided.
Ο Α
B
OD
Answer:
The non-critical factor when a person begin an exercise program is finding friends who like to exercise the same way you do.
Explanation:
Physical exercise is an ideal way to stay healthy. It is a personal activity that should be done in the best way and with a minimum risk. Finding friends who like to exercise can contribute to motivation, but it is not an indispensable element when establishing a personal exercise routine.
Since it is a personal activity that affects an individual's health, personal factors should be considered when establishing a exercise program.
Regarding the other options, which are important factors for the exercise :
Use appropriate protective equipment during exercise, allows to avoid injuries during physical activity.See the doctor for a physical assessment prior to beginning exercise, establishing the state of health and physical condition appropriate for this activity.Choose clothing that is designed to match your exercise program, which must be comfortable and light, allowing maximum performance to be achieved.19.

Distinguish the difference between dehydration synthesis, and hydrolysis?
Explanation:
In dehydration synthesis reactions, a water molecule is formed as a result of generating a covalent bond between two monomeric components in a larger polymer. In hydrolysis reactions, a water molecule is consumed as a result of breaking the covalent bond holding together two components of a polymer.

Which best describes when the body is working on counteracting an effect? when hormone levels in the body are all equal during a negative feedback loop during a positive feedback loop when the hypothalamus is signaling the pituitary gland
Answer:
The answer is a negative feedback loop. Negative feedback is used to counteract an effect and achieve back a homeostatic balance. An example of a negative feedback loop is in thermoregulation. When temperatures are too high, the hypothalamus induces body responses such as vasodilation and sweating that enable the loss of excess heat.

Any group of organic compounds consisting of carbon,
hydrogen, and oxygen
(5 Points)
carbohydrates & lipids
carbohydrates & proteins
proteins & nucleic acids
nucleic acids & lipids
Answer:
The most correct option is carbohydrates & lipids
Explanation:
Carbohydrates are organic compounds that contain carbon, hydrogen and oxygen [for example starch, (C₆H₁₀O₅)ₙ] while lipids generally contains carbon, hydrogen and oxygen [for example fatty acid, CH₃(CH₂)ₙCOOH] but could also contain other elements like sulphur and phosphorus.
Proteins are made up of building blocks called amino acids. Amino acids are made up of an amino group which consist of nitrogen and hydrogen. Hence, proteins have a large number of nitrogen atoms thus not part of the answer.
Nucleic acids are composed of nitrogenous bases and phosphate groups and are also not part of the answer for this reason.
How does the genetic code for an entire human being fit into the microscopic nucleus of a skin sell?
Answer:
The DNA of each chromosome is coiled, compacted, and coiled up some more.
Explanation:
Genetic code is the nucleotide sequence of DNA which is compacted to a chromosome to fit in the skin cell by the protein which compacts the long DNA into the small chromosome.
What is DNA organization?Levels of DNA Compaction nucleosomes, which resemble "beads on a string," are formed when double-stranded DNA is wrapped around histone proteins. A 30-nm chromatin fiber is formed from the nucleosomes.
The chromosomes narrow more during mitosis in a cell. In the S phase of interphase, DNA replication occurs. To create chromosomes, the chromatin fibers are further coiled and compressed.
Chromosome DNA is crammed into the eukaryotic nucleus little area by proteins. The resultant DNA-protein combination is known as chromatin, and these proteins are known as histones.
Therefore, the proper sequence is DNA, Nucleosome, Chromatin, and Chromosome, so by this organization genetic code of an entire human being fit into the nucleus of a skin cell.

What cell process is this and how do you know !
Answer:
Explanation:
Cell reproduction is the process by which cells divide to form new cells. Each time a cell divides, it makes a copy of all of its chromosomes, which are tightly coiled strands of DNA, the genetic material that holds the instructions for all life, and sends an identical copy to the new cell that is created.

A. they store pigments
B. they store enzymes
C. they store water
D. they store ribosomes
Answer:
They store water
Explanation:
The unique function of vacuole in a plant cell is the storage of water.
FUNCTION OF VACUOLE:
Vacuoles are organelles bound by a membrane and present in both animal and plant cells. They are fluid-filled spaces in the cytoplasm of a cell. Vacuoles are present in the central position of a plant cell, where it occupies more than half of the cell's content. Vacuoles help plant cells to store water and maintain turgidity and homeostasis in the cells of plant.Therefore, vacuoles help the plant cell to store water.
