Describe the femur.
A femur is just the bone in the thigh. That is the longest and sturdiest bone in the human body. The capacity to stand + walk depends on it. Numerous crucial muscles, ligaments, tendons, other components of the circulatory system are supported by the femur as well.
How bad is a fractured femur?
A fractured femur is a dangerous injury that has to be treated immediately by a doctor. Treatment for broken femurs includes surgery plus physical therapy. The broken femur may need several months to recover. A vehicle accident, a tumble, or even being shot all have the potential to fracture the femur. The majority of femoral fractures recover fully in around four to six months, however one should be capable of returning to most movements before then.

If a solution has a pH of 7.5, what would its new pH be if the concentration
of H₂O* ions in the solution were increased by 100 times? Explain your reasoning
The correct answer is pH of 5.5 Increasing the H3O+ by 10 fold decreases the pH by 1 unit so an increase of 100 would decrease the ph by 2 units .
When the concentration of hydrogen ions in a solution increases by a factor of ten, the pH of the solution decreases by one. The acidity of a solution is thus defined as its hydrogen ion concentration [H+] expressed as the solution pH. The pH of a solution is more precisely defined as the negative log of the hydrogen ion concentration: pH=log[H+].
Most natural changes occur as a result of interactions with surrounding rock (particularly carbonate forms) and other materials. pH can also change as a result of precipitation (particularly acid rain) and wastewater or mining discharges 13. Furthermore, CO2 concentrations can affect pH levels.

Generally, animals cannot digest (hydrolyze) the glycosidic linkages between the glucose molecules in cellulose. how then do cows get enough nutrients from eating grass?
Microorganisms in their digestive tracts hydrolyze the cellulose to individual glucose units.
Cellulose- The stable formation of plant cell walls is greatly aided by cellulose, a hard, fibrous, and water-insoluble polysaccharide. The fibrils (bundles of microfibrils) and microfibrils (bundles of polysaccharide) made up of cellulose chains make up the plant cell wall.
Glucose- The primary form of sugar in the blood, glucose serves as the body's cells' principal source of energy. Glucose may be produced by the body from other chemicals or it can be obtained from the meals we eat. The circulation carries glucose to the cells. Insulin is one of many hormones that regulate blood glucose levels.

Cell damage may be caused by exogenous sources such as:_____.
a. abnormal metabolic processes.
b. certain food additives.
c. genetic defects.
d. localized hypoxia.
Cell damage may be caused by exogenous sources such as abnormal metabolic processes. So the correct option is A.
What is cell damage?If enough cells are destroyed as a result of toxic damage to cells, there may be tissue or organ failure, which eventually results in organism death. Discussions of cellular toxicity and biochemical toxicity are essentially inseparable.
The majority of detectable cellular alterations and cell death are brought on by certain biochemical alterations either inside the cell or in the tissue around it. There are, however, a few circumstances in which a harmful chemical or physical substance might harm cells without actually altering any particular chemicals present in the cell or its membrane.
Physically damaging substances like heat and radiation can harm a cell by coagulating its contents (similar to cooking). There are no particular chemical reactions in this situation. A cell may be deprived of vital supplies necessary for existence due to a compromised food supply (such as oxygen and glucose).
Therefore the correct option is A.

Define osmosis and explain why it biologically important.
Explanation:
osmosis
refers to the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules through a cells partially permeable membrane
Importance
- it stabilizes the internal environment of the organism by balancing the level of water and intracellular fluids
General category: Biology.
Sub-category: Cellular membranes
Topic: Diffusion
Introduction:
Diffusion is the random movement of molecules in a given medium toward a state of equilibrium. Then, diffusion is the net movement from regions of greater concentration to regions of lesser concentration.
Explanation:First of all, remember that if a cell membrane divides a solution into separate compartments, the movement of the different solutes can be affected by the properties of the membrane. The passage of substances depends on whether the membrane is permeable or semi-permeable to different solutes.
Now, the concept of osmosis is based on the idea of diffusion. Osmosis is the diffusion of water across membranes. This means that water will diffuse from a region of its higher concentration (lower concentration of solutes) to a region of its lower concentration (higher concentration of solutes).
Osmosis is vital to maintain the osmotic equilibrium necessary for the cell to function. Remember that osmotic equilibrium is the ratio of intracellular fluid to the extracellular fluid. For example, osmotic balance is of vital importance in the functioning of the nephron.
We can conclude that the correct answer is:
Answer:Osmosis:
Osmosis is the diffusion of water across membranes where the water will diffuse from a region of its higher concentration to a region of its lower concentration.
Biological importance of osmosis:
Osmosis is vital to maintain the osmotic equilibrium necessary for the cell to function.

record the growth of the organisms over another ten-week period, this time in
water that averaged 25°C
After recording the growth of the organisms over another ten-week period, this time in water that averaged 25°C the temperature of the medium causes the growth graph to fluctuate up and down.
The line climbs upward due to the existence of the optimal temperature for the growth of that organism, which grows best in the temperature range of 15°C to 25°C.
The graph swings downward because the water temperature is unsuitable for the growth of that organism, which grows best in the temperature range of 5°C to 15°C.
We can infer that the growth rate changes owing to water temperature as the organism grows best in the 25°C to 35°C temperature range and the graph swings downward because the water temperature is not conducive to its growth.

In eukaryotes, Messenger RNA is specific to the synthesis of only one type of protein.
Messenger RNA or also known as mRNA is a single stranded RNA molecule and it carries genetic information of DNA to convert into proteins. It is created when enzyme (RNA polymerase) converts the gene into primary transcript mRNA.
The genetic code taken by mRNA is first converted to amino acids which then is used to synthesize protein. Genetic information of DNA is stored in mRNA in the sequence of nucleotides which are then arranged into codons. Each Codon is specific for an amino acid but the stop codon is used to stop the protein synthesis.

%H₂0
15%
solute
80% H₂O
% solute
Correct. The solution in the beaker is hypertonic to the cell interior because its solute concentration is about 20%, which is greater than 15%. Water tends to leave the cell.
What are hypotonic and hypertonic solutions?When placing two solutions together separated by a membrane, we can classify them according to their solute concentration,
A hypertonic solution is the one with the higher solute concentration. It is the most concentrated solution.
A hypotonic solution has lower solute concentrations. It is the most diluted solution.
Isotonic solutions have the same solute concentrations.
In this example, we will assume the circle is a cell,
Cell interior ⇒ 85% water + 15% soluteBeacker solution ⇒ 80% water + 20% soluteThe solution in the beaker is hypertonic to the cell interior because its solute concentration is about 20%, which is greater than 15%.
The interior of the cell is hypotonic to the solution in the beaker, because it is more diluted. It has 85% water, which is higher than 80% water. Water tends to leave the cell moving forward to the beaker solution.
