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.

What is the manipulated variable in this experiment?
O A. The distance the snails moved
OB. The size of the petri dishes
C. The temperature of the water
D. The number of snails observed HELP ME
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.

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.

(PLEASE HURRY)Strong winds blow sand to a new location, and some of the sand forms a sand dune. The first plant species to live in the new habitat of the sand dune is a type of grass. 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?
A.
The grass cannot reproduce fast enough to cover all of the growing dune.
B.
New plants are better suited to the new conditions in the sand dune habitat.
C.
The grass moves to new sand dunes to start the succession process again.
D.
New animals come to the new sand dune habitat and eat the grass.

9. Because the sun heats sections of the Earth more or less, and hot
and cold air wants to move in certain directions, this causes
air currents, or
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.Study this image. PLEASEE HELPP WILL GIVE BRAINLYEST

Answer:
Gymnosperms:-
non-flowering, exposed seeds, pine, or fir fruit.
Angiosperms:-
flowering, seeds enclosed in fruit, garden flowers, and tomatoes
Explanation:
Gymnosperm
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
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.
how is the cell able to make the many different proteins it needs? In your answer, be sure to: identify where in the cell the information necessary to make a particular protein is located and the specific molecule that contains this information AND identify both the cellular structure that makes these proteins and the kinds of molecules that are used as the building blocks of the protein
Answer:
Explanation:
Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell.

Answer:
This is an example of positive feedback response
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.
