10. In the figure of the U-tube below, side "A" is pure water and side "B" is a 10% starch solution. The starch can not pass
through the membrane because it is too large, only the water moves across the membrane. Explain what has
happened in the before and after picture below. Why does this happen?
Answer:
All of the water has moved through the membrane moving the solution on the other side higher.
Explanation:
I really hope this is right and i helped you out!
Starch cannot pass through membrane because it is too large molecules. Cell membrane is a semipermeable membrane. It cannot allow bigger molecules to pass. It helps only to pass small molecules.
What is cell membrane?A cell membrane, often referred to as a plasma membrane, is present in every cell and serves as a barrier between the interior of the cell and the outside world.
The cell membrane is a lipid bilayer that is semipermeable. The cell membrane regulates the flow of substances into and out of the cell.
The cell membrane, commonly referred to as the plasma membrane, serves as the body of a cell. It also keeps the environment inside the cell constant, and that membrane has many functions.
Therefore, Starch cannot pass through membrane because it is too large molecules. Cell membrane is a semipermeable membrane. It cannot allow bigger molecules to pass. It helps only to pass small molecules.

While playing tennis you need to know where your limbs are located so you can move them into the right positions to run or swing your racket. Which of the following senses provides this information?
Answer:
The correct would be - Kinesthesis.
Explanation:
Kinesthesis is the study of the body movement and learning where is your body parts and so can you can move or find the required changes to make to the body and its part. It does not depend on the senses like hearing, vision, or others.
Kinesthesis involved the sensory receptors present in joints, muscles or other body parts involves in making movements and allows to make and understand physical activities. For example, sensing pr knowing where is the body limbs to move to hit or swing the racket or run.

Which of the following is not a potential result of a bottleneck event?
a. an increase in potential mates
b. a decrease in genetic diversity
an increase in inbreeding
d. an increased chance of extinction
C.
Answer:
A. An increase in potential mates
Explanation:
An increase in potential mates would not be a potential result of a bottleneck event because it would actually increase the population rather than kill them off.
HAVE A GOOD DAY!!!!
Event an increase in potential mates is not potential result of a bottleneck.
What is the bottleneck effect for example?The bottleneck effect is an extreme example of genetic drift that occurs when the size of a population is severely reduced.
Events like natural disasters (earthquakes, floods, fires) can decimate a population, killing most individuals and leaving behind a small, random assortment of survivors.
Thus, option "A" is correct.

That is not true! Fossils are found in from germany to australia (all around the world)!
The study of fossils is called paleontology. On earth, there are different types of fossils present on the earth. For example Body Fossils, Molecular Fossils, Trace Fossils, Carbon Fossils, Pseudofossils.
The correct answer is option A.
What are fossils?A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnantsAccording to the question, all the options are relatable to the good fossils index except option A.
The fossils can be found anywhere on the earth, not at a specific location.

In an organ transplant, a doctor transfers a donated organ from a recently deceased person to a live patient. One of the consequences is that the patient's immune system - the system that protects against diseases and pathogens in the body will reject the new organs. Explain why this consequence isn't a concern with organs grown from human cells
Answer:
The scientist would use the patient’s own stem cells to grow the organ. Because the cells are from the patient’s own body, the immune system won’t perceive the new organ to be a foreign body.

What is a T-cell receptor?
Answer:
The T-cell receptor (TCR) is a protein complex found on the surface of T cells, or T lymphocytes,[1] that is responsible for recognizing fragments of antigen as peptides bound to major histocompatibility complex (MHC) molecules. The binding between TCR and antigen peptides is of relatively low affinity and is degenerate: that is, many TCRs recognize the same antigen peptide and many antigen peptides are recognized by the same TCR.

What do you notice about the water molecules?
Answer:
Explanation:
they have 2 OH bonds - which are hydrogen bonds,
they're polar due to the difference in electronegativities of oxygen and hydrogen
Answer:
Why do phase changes occur?
1. Compare: Set the Water temperature to 0 °C and click Play. Observe the water molecules.
Click Reset, set the Water temperature to 100 °C, and click Play again.
What do you notice? The water molecules are moving slightly faster at 100 °C than at 0 °C.
[Note: This difference may be too small to observe easily.]
2. Observe: Click Reset. The mean molecular speed of the water molecules is displayed
below the container. Set the Water temperature to 0 °C and Add/remove heat energy to
400 J/s. Click Play.
A. How does the mean speed of the water molecules change as they are heated?
The average speed of water molecules increases as they are heated.
B. Does the mean molecular speed change as much as the temperature as the
water heats up? Explain.
Sample answer: For each degree of temperature change, the mean molecular
speed increases by about 1 m/s. At 100 °C, the mean molecular speed is about
17% faster than at 0 °C.
3. Explain: How is temperature related to the motions of molecules?
The higher the temperature, the faster the molecules move.
4. Observe: Click Reset. Set the Water temperature to 20 °C and the Ice volume to 50 cc.
Set Add/remove heat energy to 0 J/s. Click Play. How do the molecules in the liquid
interact with the molecules in the solid?
The molecules of the liquid collide with the molecules of solid, gradually breaking the bonds
between the molecules in the solid and causing the ice to melt.

Translate the mRNA into the corresponding amino acids.
mRNA Molecule:
AUGAACCAUUCAGUAUGG
Amino Acid( fill) :
The corresponding amino acids would be
UACUUGGCAAGUCAUACC
The given mRNA sequence can be translated into the corresponding amino acid sequence as Methionine-Aspargine-Histidine-Serine-Valine-Tryptophan.
RNA ribosome translation is the process by which mRNA is translated into proteins. A ribosome is a cellular structure composed of proteins and rRNA. It is the site of translation, where codon codons are matched to amino acids and peptide bonds are formed between amino acids.
All mRNAs are degraded at a specific rate once they enter the cell’s cytoplasm. Some mRNAs are translated, some are stored for further translation, and some mRNAs are temporarily translational repressed.

It is the Large density of fish in a small holding area that is when the production is increased to a greater number. The correct answer is option B.
What are the common diseases that may cause effects in fish ?These could be pathogenic invasions on their bodies. It can be them not feeding as well.
Risks that include amplification and the transmission of the disease that from the farmed to the wild fish along then the introduction of the non native kind of the pathogens along with the parasites in case when the fish are transported. Fish diseases takes place naturally in wild but effects often can go on unnoticed as the dead fish suddenly becomes prey.
Signs of the fish disease mainly include the abnormalities and symptoms as fish is not feeding that are having ulcers on body or the cloudy eyes.

what is the difference between cell membrane and visking tubing
Explanation:
cell membrane- is a semipermeable tissue that selectively allows the movement of materials in and out of a cell while a visking tubing is a artificial cee membrane
Answer:
Explanation:
Cell membrane is a semi permeable wall found in living cells . It is separate the inside cell from the the outside environment. This allow the movement of substances in and out of the cell. It allow diffusion of gases in and outside the cell.
Visking tubing is made of regenerated cellulose which look aliitle bit similar sellotape when it is dry. It is an artificial membrane that is similar to the cell membrane. It is a selectively permeable membrane with small pores that allow the movement of smaller molecules in through them.
