Someone plz help me I have to turn it in ASAP it was due past Thur. PLZ PLZ I’ll appreciate the help PLZ!!!!!!!! I beg u!! ♥️
Answer:okay so I did it it was very fun so here are my results EXPERIMENTAL DATA Before After 24 hours
Color of Starch solution It was a whitish color. Dark, purple, black color. inside bag!Color of Iodine solution A golden color. A transparent creme inside beaker color. Color of starch solution White White inside bag! Color of H20 in beaker TransparentExplanation: Conclusion
The conclusion to this test is that the plastic bag is permeable to iodine. The result
of this experiment clearly answers the "Problem" as stated above. This is~ by
the fact that the starch solution (dependent variable) in the baggie turned purple,
indicating the presence of iodine (independent variable) in the mixture. The starch
solution is the dependent variable because its color is affected by the iodine
solution. M.y hypothesis was that the iodine will get into the bag of starch because
the baggie is permeable to iodine. If the iodine solution penetrates the bag, it will
turn the starch solution inside the baggie, purple. The control data chart above
shows that if the starch had not been immersed in the iodine solution, but rather a
water solution, it would have remained the same color, white. Obviously, in order
for the iodine to enter the starch solution, the baggie must be permeable to the
iodine. The baggie represents a cell membrane. This lab is meant to demonstrate
whether or not a cell membrane is permeable to substances. Cell membranes of
living organisms may be permeable to some substances, but not permeable to other
substances. In this experiment,'1..charted that the iodine solution in the beaker did
not turn purple. This means that the starch solution did not penetrate the baggie
and therefore did not mix with the iodine outside the baggie. Because of this data, it
is clear that the plastic baggie is not permeable to starch, but is permeable to iodine.
In a cell membrane, this is called selective permeability. In other words, the iodine
can go through the baggie, but the starch cannot. The purpose of this experiment is
to show that a cell membrane is a type of barrier, and is permeable to some
substances, but may not be permeable to all substances. Therefore, a cell membrane
is selectively permeable.
The fossils of a few organisms are shown below. The first image is a bird, the second image is a dinosaur, and the third image is an Archaeopteryx. The dinosaur fossils were obtained from the lower sedimentary layer, and Archaeopteryx was found above it. The fossils of the bird were found on the topmost layer, which suggests that they’re the_____ . This information also suggests that Archaeopteryx _______.
-21 POINTS-
Answer:
They're the Youngest. This information also suggests that Archaeopteryx was once thought to be the oldest known fossil bird.
Explanation:
Hope this helps.
Based on the principle of superposition, we can conclude that the topmost layer is the youngest. Hence, the fossil of birds is the youngest, while Archaeopteryx is younger than dinosaur fossil.
According to the principle of superposition, sedimentary deposits are layered such that, the oldest layer is at the bottom and the youngest is the topmost layer.
Hence, dinosaur fossil are the oldest, followed by Archaeopteryx, then birds.

Which statement best explains the relationship between producer and consumers in terms of
energy?
A. Consumer produce glucose that producer's use for energy B. Consumers convert carbon dioxide into energy
C. Consumers provide energy for producer to undergo aerobic respiration
D. Consumers convert glucose from producers into ATP
please only reply if you know the answer
Answer:
> Consumers convert glucose from producers into ATP.
Explanation:
Consumers do NOT provide oxygen or glucose for producers.
The statement, consumers convert the glucose from producers into ATP. So the correct option is D.
What are producers and consumers?In feeding chains, organisms are categorized into trophic levels. Producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers roughly correspond to these levels.
Autotrophs, another name for producers, grow their own food. Every food chain's first level is comprised of these. Plants or single-celled creatures represent the majority of autotrophs. The majority of autotrophs produce their "food" (a nutrient called glucose) from sunlight, carbon dioxide, and water through a process known as photosynthesis.
The most well-known form of autotroph is a plant, but there are numerous others as well. Algae are autotrophic, and their bigger forms are known as seaweed. Autotrophs include the small sea life known as phytoplankton. Autotrophic bacteria include certain varieties. For instance, microorganisms that live in volcanoes that are still active utilize sulfur compounds to make their own food. Chemosynthesis is the name of this process.
Therefore the correct option is D.

Answer:
Function
Explanation:
The shape of the cell, the organelles within it as well as how many of those organelles are present play a huge role in the cells function.
For example, muscles cells will have lots of mitochondria that are used for ATP production, needed in movement.
Lung cells will have ridges or groves in them that increase the cells surface area that make them much more effective at the diffusion of oxygen and carbon dioxide when breathing.

if coral reef continue to die off how do you think that would affect specialist species such as butterfly fish overtime?
Answer:
If coral reefs continue to die off, I think it would have a huge impact on specialist species such as the Butterfly Fish overtime. If there are less reefs for fish to call home, that leaves less hiding places from predators, less food for such creatures, and higher risk of extinction.
Neurons, as with other excitable cells in the body, have two major physiological properties: ____________ and ____________. A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the ____________. This system moves ____________ out of the cell and ____________ into the cell. The inside of the cell membrane is negative, not only due to the active transport system but also because of ____________, which remain negative due to the intracellular pH and keep the inside of the cell membrane negative.
Answer:
Neurons, as with other excitable cells in the body, have two major physiological properties: irritability and conductivity. A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the sodium potassium pump. This system moves sodium (Na+) out of the cell and potassium (K+) into the cell. The inside of the cell membrane is negative, not only due to the active transport system but also because of intracellular proteins, which remain negative due to the intracellular pH and keep the inside of the cell membrane negative.
Explanation:
Neurons are cells with the capacity to transmit information between one another and also with other tissues in the body. This information is transmitted thanks to the release of substances called neurotransmitters, and this transmission is possible due to the electrical properties of the neurons.
For the neurons (and other excitable cells, such as cardiac muscle cells) to be capable of conducting the changes in their membranes' voltages, they need to have a resting membrane potential, which consists of a specific voltage that is given because of the electrical nature of both the inside and the outside of the cell. The inside of the cell is negatively charged, while the outside is positively charged - this is what generates the resting membrane potential. When the membrane voltage changes because the inside of the cell is becoming less negative, the neuron is being excited and - if this excitation reaches a threshold - an action potential will be fired. But how does the voltage changes? This happens because the distribution of ions in the intracellular and extracellular fluids is very dissimilar and when the sodium channels in the cell membrane are opened (because of an external stimulus), sodium enters the cell rapidly to balance out the difference in this ion concentration. The sudden influx of this positively-charged ion is what makes the inside of the neuron become less negative. This event is called depolarization of the membrane.
