Answer:osmosis
Explanation:
Answer:
Water, carbon dioxide, and oxygen.
Explanation:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

what are the products of photosynthesis
Answer:
glucose and oxygen
Explanation:
Calcium, IP3, and cyclic AMP are all small molecules that can be found inside most cells, yet they are known to be important second messengers that can increase or decrease in response to a wide variety of signals. However, each signal often produces completely different responses. Give an example of this phenomenon, and explain how such responses occur.
Answer:
they are second messenger molecules capable of triggering different signaling pathways
Explanation:
Second messenger molecules are intracellular signaling molecules that trigger different cellular responses. Examples of second messengers include Calcium ions (Ca2+), Inositol trisphosphate (IP3), and cyclic AMP (cAMP). Secondary messengers may be activated by different cellular responses, for example, cyclases that synthesize cAMP or by opening calcium ion (Ca2+) channels. For example, cAMP signaling is able to activate kinase enzymes that perform phosphorylation and interact with other effector molecules to mediate different biological functions (for example, regulation of glycogen and sugar metabolism). On the other hand, Ca2+ signaling is required for muscle contraction, neurotransmitter release, etc. Ca2+ signaling is known to exert allosteric control over enzymes and other types of proteins.

Explanation:
what is the full form of tree
Explanation:
A tree or large tree is called a long-standing woody plant. In botany, the tree is one of the most durable plants that maintains its leaves by growing a stem or trunk. In some definitions, the use of the tree is such that it is the only woody plant. It is the only plant from which wood is obtained. It is not possible to determine the exact height of the trees, but overall the adult trees reach at least 6 meters [citation needed]. In the structure of the tree there are usually branches that are attached to a large trunk. Compared to other plant and animal species, trees have a long life. Some species of trees are more than 100 meters tall, and some live for thousands of years. Trees are important elements of natural landscape, gardening and landscaping. [1]

Explain how an uncontrolled mutation in a single cell can lead to the development of a tumor and cancer
Answer:
.........................
Explanation:
Eventually, the pace of the cell cycle speeds up as the effectiveness of the control and repair mechanisms decreases. Uncontrolled growth of the mutated cells outpaces the growth of normal cells in the area, and a tumor can result.

Describe the four levels of protein structure. For each level, include: the name of that level of structure how the protein is arranged at that point in time Answer using 4 to 5 complete sentences.
here are the structures i hope it helps
Answer:
primary, secondary, tertiary, and quaternary.
Explanation:
four levels of protein
1. primary structure of a protein: this is the number and sequence of amino acids held together by the peptide bond in a polypeptide chain.
2. secondary structure of a protein: this described the interaction of the sequence of amino acids in a polypeptide chain, and the bond formed is hydrogen bond.
3. tertiary structure of a protein this is a 3 dimension structure of a protein in the polypeptide chain and the bond formed are hydrogen bond, ionic bond and disulfide bond.
4. quartenary structure of a protein this is a combination of more than one structure which is primary structure, secondary structure and tertiary structure. bond formed are disulfide bond and so on.

Please help this is due at 11:59 tonight!!! Jimmy and Jenny have designed an experiment to test how termites react to the chemicals in ink pens. They use one termite in their experiment. Jenny draws four circles, using four different brands of black ink. Jimmy places the termite on each circle of ink and they watch the termite's behavior as it is placed on each circle, one try per circle. In all four cases, the termite veers off the ink circle. Jimmy and Jenny conclude that termites are not attracted to ink at all. What suggestion would you give Jimmy and Jenny concerning their experimental design?
A. Compare the termite’s behavior on ink circles to the behavior on pencil circles.
B. Run repeated trials with the one termite.
C. Use more than one termite and run many trials.
D. Use more than one termite and the same brand of ink pen each time.
Answer:
Use more than one termite and run many trials.
Explanation:
it's not A because we're not trying to figure out pencil's but the chemical's in ink. It's not B because using just one bug wouldn't really get us anywhere. It's not D because you'd actually want to try different brands of ink to see if maybe you had a lesser chemical ratio. It's C because not all the bugs will react in the same way as just one would. Also, doing multiple trials would show us if they would change their behaviors.
In general, how do sensory systems function?
Answer:
Sensory nervous system detects and encodes stimuli and then sends signals from receptors. (evidence below for a clearer answer)
Explanation:
"As a whole, the sensory nervous system detects and encodes stimuli and then sends signals from receptors, that is, sense organs or simple sensory nerve endings, to the central nervous system, that is, it transduces environmental signals into electrical signals that are propagated along nerve fibers."

An intestinal epithelial cell powers the movement of glucose into the cell against its concentration gradient by simultaneously transporting sodium down its concentration gradient. Which transport mechanism is responsible?
primary active transport
Secondary active transport
osmosis
facilitated diffusion
Answer:
Secondary active transport by a symporter
Secondary active transport includes uphill transport of one substance against its concentration gradient coupled with downhill transport of another substrate. Glucose is transported against the concentration gradient into the cytoplasm and this active transport is driven by downhill transport of Na+ into the cells. This makes the transport of glucose a secondary active transport. Both glucose and Na+ are transported into the cell (in the same direction). Since both are moved simultaneously in the same direction, it is a symport.
Explanation:
Answer:
Primary osmosis diffusion
Explanation:
That is because intestinal cells give glucose to concentrional cells by transporting coca colas from walmart to ikea.
