Describe how the jump rope could be used to model the cell membrane of a plant
cell.
Answer: Plants can use the energy from sunlight to turn water and carbon dioxide into. When the cell has enough organelles to make two cells, the division process starts. Let's discuss the process of photosynthesis again, this time taking a closer look at it. Just A long rope to represent the cell wall.
Jump rope is thin and elastic which is made by twisting two threads together which somewhat looks like a cell membrane can be used as a model for plant cell membrane.

Studies of autonomic nerve regeneration have demonstrated that Group of answer choices preganglionic fibers show a strong preference for innervating their normal postganglionic targets. only sympathetic fibers can regenerate accurately. regeneration is extremely precise; each preganglionic fiber reestablishes synapses on the exact same postganglionic cells that they previously innervated. autonomic regeneration occurs randomly onto both ganglion cells and target tissues. only parasympathetic fibers can regenerate accurately.
Answer:
only sympathetic fibers can regenerate accurately
Explanation:
Neuroregeneration is a complex biological process associated with the regrowth and/or repair of nervous tissues. This process depends on the type of nerve tissue and how seriously the nerve was injured. The autonomic nervous system, also known as the autonomic nervous system (ANS), is part of the peripheral nervous system (PNS) that is responsible for regulating involuntary physiological processes. The PNS contains two basic divisions: sympathetic and parasympathetic. The sympathetic fibers innervate tissues in nearly all the organ systems and they are responsible for regulating homeostatic processes (e.g., heart rate). The sympathetic nervous system is formed by nerves from the thoracic and lumbar segments of the spinal cord. These autonomic nerves can regenerate after injury in order to reinnervate target tissues (e.g., after chronic cardiac ischemia).

In the presence of lidocaine, the action potential was NOT affected at R1 because _______. In the presence of lidocaine, the action potential was NOT affected at R1 because _______. lidocaine doesn't have an effect on the generation of action potentials lidocaine was applied upstream of R1 lidocaine was applied downstream of R1 there are no voltage-gated sodium channels to be affected
Answer:
In the presence of lidocaine, the action potential was NOT affected at R1 because lidocaine was applied downstream of R1
Explanation:
Lidocaine is an anesthetic that has the power to neutralize neuromal membranes. This anesthetic power allows the ionic fluxes capable of stimulating impulses to be diffused and this allows a dormancy to be achieved. However, when lidocaine is applied downstream to a molecule or structure, the action potential of that structure or molecule is not affected and it may continue to receive impulses.

4. Who are universal recipients? Why?
I'm trying to hurry I forgot my notebooks at school so please HELP!!!!!!!!!!!!
Answer:What is an antigen?
a toxin or other foreign substance which induces an immune response in the body, especially the production of antibodies.
Why is it important to match blood types when giving a blood transfusion?
The accurate grouping of blood is very important when it comes to having a blood transfusion. If blood is given to a patient that has a blood type that is incompatible with the blood type of the blood that the patient receives, it can cause intravenous clumping in the patient's blood which can be fatal.
Why are people with type O blood called "universal donors"?
Type O-negative blood does not have any antigens. It is called the "universal donor" type because it is compatible with any blood type. ... Minor antigens (other than A, B, and Rh) that occur on red blood cells can sometimes also cause problems. So they are also checked for a match before giving a blood transfusion.
Who are universal recipients? Why?
Type AB-positive blood is called the "universal recipient" type because a person who has it can receive blood of any type. Although "universal donor" and "universal recipient" types may be used to classify blood in an emergency, blood type tests are always done to prevent transfusion reactions.

Garlic mustard has been introduced to the beetles ecosystem. Describe what would happen to the beetles population as a result and explain why.
Answer:
It would collapse
Explanation:
Garlic mustard also produces root exudates that inhibit the growth of important soil fungi and leaf chemicals that kill native butterfly larvae that feed on the plant
In addition, invertebrates and other consumers that rely on these natural plant species for food are harmed by the spread of this invasive "weed". Garlic mustard also produces root exudates that inhibit the growth of important soil fungi and leaf chemicals that kill native butterfly larvae that feed on the plan
Garlic mustard is an invasive plant species that is known to negatively impact native plant populations in ecosystems.
What is invasive plant?An invasive plant is a non-native plant species that is introduced to an ecosystem and has the ability to spread and negatively impact native plant and animal populations.
Garlic mustard is known to release chemicals that inhibit the growth of other plant species, including some that the beetles may rely on for food.
This could lead to a reduction in food availability for the beetles, which may cause a decline in their population.
Additionally, if the beetles are not adapted to feeding on garlic mustard, they may not be able to digest or utilize the plant efficiently, leading to further declines in population.
Thus, the impact of garlic mustard on the beetle population will depend on the specific beetle species and the extent to which they rely on native plant species for food.

which statement best differentiaates between weather and climate
Answer:
Weather refers to short-term atmospheric fluctuations, whereas climate explains the weather in a certain place over a long period of time.
Explanation:
Globally, weather conditions are measured at hundreds of locations every day of the year by observers and automated stations. Some remarks are made every hour, others perhaps once a day. In the long run, these weather observations allow us to quantify average long-term conditions, giving an insight into the climate of the region.
Systemic weather records have been recorded for over 140 years in various places in the United States. We can recognize patterns and trends with these long-term records. And it's our mission to collect, monitor, and arrange these data, as the official repository of the Nation for environmental data, for scientists, decision-makers, and you online.
Proteins are important food nutrients. A technician working at a food company is interested in the nutritional content of seeds/nuts. She runs a PAGE with samples from two different seed extracts. She runs multiple lanes of the staples. The gel is stained with Coomassie Blue. Seed extract No. 1 has three faint bands at 25, 30, and 35 kDa. Extract No. 2 has two bands at 25 and 35 kDa, and the bands are very dark. What might she conclude from her results about the nutritional value of the seed extracts
Answer: Sample 1 then, has more variety of proteins but less quantity of each one, while sample 2 has less variety but more quantity of the two proteins present.
Explanation:
Proteins are molecules found in the cells of all living organisms. A protein is composed of monomers called amino acids linked together by peptide bonds. To analyze proteins, a technique called SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis) is used. This technique is used to separate proteins according to their electrophoretic mobility, depending on polypeptide chain length, molecular mass, post-translational modifications and other factors. SDS (sodium dodecylsulfate) is an anionic surfactant compound that breaks non-covalent bonds in proteins, denatures them causing these protein molecules to lose their native conformation and provides the polypeptide with a negative charge that is proportional to the chain length (the number of amino acids) and, therefore, to the molecular mass of the protein. The electrostatic repulsion created by the binding of SDS to the protein is one of the causes of the protein losing its native conformation, thus eliminating the differences in conformation of the different proteins to be separated in the gel.
An electric current is applied to the gel where the proteins are seeded, causing the negatively charged proteins to migrate through the gel in the direction of the anode (positively charged region). Short proteins will move more easily and faster through the pores of the gel, while larger proteins will find it more difficult to do so. After a certain time, the proteins will have migrated according to their size (measured in kDa or kiloDaltons). After electrophoresis, the gel should be stained with Coomassie blue or silver stain, allowing visualization of the separated proteins. After staining, the different proteins will appear as distinct bands on the gel. In addition, the higher the amount of a protein, the more intense the color of its band will be.
Extract No. 1 shows three bands: 25, 30 and 35 kDa. This means that it has three different proteins, each with a different molecular weight. Extract number 2 shows two bands: 25 and 35 kDa. It means that this sample has only 2 proteins. And being bands of higher intensity, we can say that there is more of each protein.
Sample 1 then, has more variety of proteins but less quantity of each one, while sample 2 has less variety but more quantity of the two proteins present.
