Answer:okay so I did it it was very fun so here are my results EXPERIMENTAL DATA  Before After 24 hours

Explanation: 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.

Hey!

Your answer is CO-ENZYME!

Explanation:

What do CO-ENZYMES do?

They are an organic (but not protein based) compound...they act in a reaction by assisting the enzymes to bind and react with another substance...this then makes the reaction even faster!

But they cannot ever work by themselves to catalyse a reaction!

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.

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.

Explanation:

Trypsin is a serine protease enzyme capable of hydrolyzing different types of proteins. This enzyme is used in biotechnology and molecular biology to hydrolyze at the carboxyl side of arginine or lysine residues. Moreover, chymotrypsin is another digestive protease that also catalyzes the breakdown of proteins into small polypeptide chains. This enzyme cuts the C-terminal side of aromatic amino acids such as tryptophan (W), tyrosine (Y) and phenylalanine (F) on peptide chains.

Cells of a similar type are organized together to make tissues. Different types of tisues come together to perform a similar function as part of organs.

For example, take the organ the stomach. There are various tissues that make up the stomach, including, for example, mucosa, and muscle tissue.

The mucosa tissue of the stomach is made up of secretory cells such as parietal cells, which secrete hydrochloric acid, and foveolar cells which produce mucus that protects the lining of the stomach.

Answer:

The answer is a. petroleum

Explanation:

I just took the test and got it right.

The leading cause of global fossil carbon emissions in 2004 was petroleum. Thus, the correct option for this question is A.

Carbon emission may be defined as the process of liberation of greenhouse gases like carbon dioxide and/or their precursors into the atmosphere over a specified area and period of time. These emissions are significantly contributing to climate change across the world.

When it comes to the global fossil carbon emissions in 2004, the major cause of that was due to petroleum. During that time, people utilize a large amount of petroleum in burning activities. This stimulates the rate of carbon emission in the entire atmosphere which is harmful to the health of living organisms.

Therefore, the leading cause of global fossil carbon emissions in 2004 was petroleum. Thus, the correct option for this question is A.

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.

Answer:

This question is incomplete because of the absence of bat diagram discussed in the question

Explanation:

Humans body contains several joints that allows from movement of bones at some junctions called the "joints". Joints are points where two bones meet. Examples of the human joints include the ball and socket joints, hinge joint, pivot joint, gliding joint, saddle joint. The type of joint in the human shoulder that allows for 360 degrees rotation is the ball and socket joint. It involves a bone that has a round head like that of a "ball" which can fit into an open cup-like shape called the "socket", hence the reason for the name. This joint allows for movement in all directions.

The bat wing does not move at the same degrees (360°) as it does not move in all directions - the wing has an up and down movement which is more of a 180° movement and not a 360° movement.
