An experiment is designed to compare the effects of glucose and sucrose on the osmoticpotential of a model cell. Two dialysis bags are used, one filled with a solution of 5% by massglucose and the other with a 5% by mass sucrose solution. A given membrane is permeable towater but impermeable to glucose and sucrose. Each membrane bag is then placed in a beaker ofdistilled water for two hours. The change in mass of the glucose bag is recorded below.Solution (5% by mass) Initial Mass ofSolution andMembrane Bag (g) Final Mass of Solutionand Membrane Bag(g)Glucose in DistilledWater 10.0 13.2Sucrose in DistilledWater 10.0 ?I got this question incorrect because I said the glucose would pass through the semipermeablemembrane, however, it would be the water that passes through. One way I can prevent myself.

Answers

Answer 1

Answer:

i dont understand you're qiestion

Answer 2

Glucose can pass through the semi permeable membranes where the molecules can pass because they are soluble in water enough. The  molecules can pass through because of the solubility factors.

What is a semi permeable membrane ?

It is the semi permeable membrane where the half of the molecules get passed through the membrane. The molecules are selectively present.

Cell membranes are an example of semi-permeable membranes. Cell membranes allow small molecules such as oxygen, water carbon dioxide and glucose to pass through, but do not allow larger molecules like sucrose, proteins and starch to enter the cell directly.

Transport is helped by certain molecules as well where the few of the ions, channels and the molecules are taken up by the membrane through the selected transportation of the ions.

C. The temperature of the water
D. The number of snails observed HELP ME

Answers

The correct answer is C. The temperature of the water

Explanation:

In an experiment such as the one described about the speed of snails in water, the manipulated variable is the factor or element that is manipulated on purpose. This means the researcher or researchers slightly change this element to compare how this affects another variable. In this context, the manipulated variable is the temperature of the water because researchers used three different temperatures (cool, room-temperature, and warm), and therefore they manipulated or changed this factor. Moreover, it is expected temperature affects the distance nails move, which is the main variable.

Answers

Answer: The FDA and USDA cerate food safety programs, safeguards to protect Americans, to protect people from unsafe food. The FDA has monitoring programs for pathogens, naturaltoxins, pesticides, etc.; their methods are science-based.

The safeguards that are placed to protect Americans from unsafe food are FDA and USDA. FDA means food and drug administrator and USDA means U.S. department of agriculture.

What are FDA and USDA?

FDA stands for food and drug administrator. It is a health and food department to ensure public health and to check the food items that the citizens are consuming.

USDA stands for The United States Department of Agriculture. The department is responsible for making the laws regarding food quality, and they also develop new qualities of fruits and vegetables.

These departments are based on scientific research and methods. Many scientists work under this to save people from having bad food.

Thus, The FDA and USDA are the safeguards set up to protect Americans from tainted food.

This grass stabilizes the sand dune. Over time, the sand dune grows larger and soil forms on the surface. As these changes occur, different plant species become dominant.

Why doesn't the original grass remain the dominant plant on the sand dune?

The grass cannot reproduce fast enough to cover all of the growing dune.

Answer:

This shows the interaction between the earth and sun.

Explanation:

There is a variation in the amount of heat that reaches the different latitudes as the interaction between the sun and earth which firms different angles of incidence on the surface.  The rays of the sun are more concentrated in mid latitudes that is the tropics and are slanting towards the poles this due the tilt in axis of earth.  This variation lads the warm air to rise and reach the poles and similar the cold polar air reaches the tropics and develops a cycle of convective cells.  This leads to a latitudinal balance in temperatures.

Nonflowering and exposed seed

Gymnosperms are the group of plants that do not possess or produce the egg in the enclosed seed which makes there seed naked or exposed

Pine or fir trees

Fir and pine are trees, and more specifically conifers, which belong to the family Pinaceae. of the gymnosperm

Angiosperms

Garden flowers and tomatoes

Tomato plants and garden flowers are the plants that belong to flowering plants or angiosperms.

Seeds enclosed in fruit

In angiosperms, there is a closed ovary that enclosed the egg to protect it. After fertilization ovary turns into a fruit.

Flowering

Angiosperms are the plants that also known as the flowering plant that means these plants are able to produce flowers that are sexual organs of the plant and help in reproduction.

(4pts) Drugs, medicines, and poisons often work by acting on endogenous proteins. They do this by looking similar to a signal molecule and binding to the endogenous protein. Look up these four examples to fill in this chart. Drug, medicine, or poison Looks similar to this endogenous molecule: Binds to this endogenous protein/receptor: Muscarine Acetylcholine muscarinic receptors Prozac Serotonin serotonin transporter protein Ketamine NMDA NMDA receptor Tamoxifen estrogen estrogen receptor

Answers

Answer:

Drug, medicine, or poison: Muscarine; Looks similar to this endogenous molecule: Acetylcholine; Binds to this endogenous protein/receptor: muscarinic receptors

Drug, medicine, or poison: Tamoxifen; Looks similar to this endogenous molecule: estrogen; Binds to this endogenous protein/receptor: estrogen receptor

Drug, medicine, or poison: Prozac; Looks similar to this endogenous molecule: Serotonin; Binds to this endogenous protein/receptor: serotonin transporter protein

Drug, medicine, or poison: Ketamine; Looks similar to this endogenous molecule: NMDA; Binds to this endogenous protein/receptor: NMDA receptor

Explanation:

Muscarine is a poisonous natural product found in certain mushrooms. It is similar to acetylcholine and competes with acetylcholine at its receptor binding sites.Signs of muscarine poisoning include salivation, lacrimation, vomiting, diarrhea, abdominal pain, bradycardia, etc.

Tamoxifen is a selective estrogen receptor modulator. It is similar to estrogen and acts by inhibiting the effects of estrogen in the breast tissue. It is used to prevent and treat breast cancer in men and women.

Prozac is an antidepressant which belongs to th class known as selective serotonin reuptake inhibitors. It looks similar to serotonin and inhibits its action by competing with serotonin for its binding site. It is used for the treatment of depression disorders.

Ketamine is an NMDA (N-Methyl-D-aspartate) receptor antagonist. NMDA receptor antagonists are a class of drugs that work by inhibiting the action of the NMDA receptor. They are commonly used as anesthetics for animals and humans to induce a state of anesthesia known as dissociative anesthesia.

Explanation:

Positive Feedback Response in Biology is said to be a phenomenon that occurs when the product or the output of an event or that of a reaction changes the response of an organism to that reaction. Positive feedback response can also happen so as to increase the change or output, then the result of the reaction gets amplified and thus leading to it occuring more rapidly.

An example of positive feedback response is the one from which this question was asked. Another is uterine contractions that takes place childbirth. The hormone oxytocin, created by the endocrine system, goes on to stimulate the contraction of the uterus.
