Fatty acids from ols present in fish Diet adequate in synthetic form of folate Diot rich in fiber Diot low in sodium and high in potassium Reduced risk of neural tube Reduced risk of hypertension Reduced risk of defects and stroko cardiovascular disease Roduced risk of some types of cancer
Answer:
Reduced risk of neural tube defects- diet adequate in synthetic form of folate Reduced risk of hypertension and stroke- diet low in sodium and high in potassium Reduced risk of cardiovascular disease- fatty acids from oils present in fish Reduced risk of some types of cancer- diet rich in fiberExplanation:
As you may already know, the adequate intake of certain nutrients is very beneficial to our body and to improve and maintain our health. That's because these nutrients act in the construction of essential molecules to keep our body functioning in a healthy and adequate way. Among the numerous nutrients necessary for our health, we can mention that the adequate intake of folate has the ability to reduce the creation of possible defects in the neural tube, while a diet rich in potassium can reduce the risks of hypertension, especially if accompanied by a low sodium diet. Following this same reasoning, a diet rich in fiber can reduce the risk of cancer, in addition to promoting good bowel function. Last but not least, a diet rich in fatty acids from fish can reduce cardiovascular disease.
Compare Law of Conservation of energy and Law of Conservation of matter?
Answer:
Conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. The first kind of energy to be recognized was kinetic energy, or energy of motion. In certain particle collisions, called elastic, the sum of the kinetic energy of the particles before collision is equal to the sum of the kinetic energy.
Explanation:
Super saturated solutions are used to make rock candy. Please describe how the crystals are formed, be sure to use the terms Solute and Solvent.
Answer:
Once the solution cools, it now has more solute than it normally could have, and this is called a supersaturated solution. Once a solution becomes supersaturated, it wants to crystallize the excess solute. The solute will form crystals on any surface. In our case the surface is a string, and we are using a lifesaver candy as our “seed.”
Explanation:
Rock candy is a type of candy made by growing sugar crystals on a string or stick.
Why are Super saturated solutions used?Super saturated solutions are often used to make rock candy because they contain more solute (sugar) than the solvent (water) can normally dissolve at a given temperature.
The first step in making rock candy is to heat water in a saucepan and add sugar to it. The sugar dissolves and forms a solution as the water heats up. After that, the solution is heated until it is completely saturated.
This occurs because the super saturated solution is unstable, and the excess solute (sugar) in the solution wants to escape and form crystals.
As time passes, more sugar dissolves from the solution and adheres to the crystals on the string or stick, causing them to grow larger.
The process is repeated until the crystals reach the desired size or until all of the excess solute has been removed from the solution.
Thus, preparing a super saturated solution of sugar and water, then dipping a string or stick into the solution and allowing the excess solute to come out of the solution and form crystals on the string or stick, is the process of making rock candy.

A massive increase in the growth of a specific species of algae resulted in record-breaking levels of a potentially dangerous toxin being released into the water. A researcher hypothesizes that the unusual growth of this algal species was caused by an increase in water temperature. The researcher designs an experiment to test the hypothesis. Which of the following is the dependent variable in the researcher's experiment?
a. The growth of the algae
b. The temperature of the water
c. The concentration of toxin in the water
d. The different species of algae growing in the water
Answer:
a. The growth of the algae
Explanation:
The researcher already knows that the over-growth of algae species results in excessive levels of a potentially dangerous toxin being released. But he/she wants to know what is causing this algae over-growth. The principal hypothesis is that the increase in water temperature is the cause of the unusual growth of this algal species. The researcher hypothesizes that the higher the temperature levels are, the more growth rate the algae will exhibit.
So in this experiment, the researcher can voluntarily modify the temperature in order to see how it changes the algae growth.
Before answering the question, let us remember a few concepts.
Independent (manipulated) variable refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. The Dependent variable reacts to any modification of the independent variable. Any change in the manipulated variable provokes a proportional or inversely proportional change in the dependent variable. It represents the quantity of something, such as height, weight, length, rate, etc. It is usually identified by the letter Y.Now, let us analyze the options.
c. The concentration of toxin in the water. This is a dependent variable, which depends on the algae growth. The more algae present, the more toxins. However, this is not what the researcher is studying. He/She wants to know what is causing the increase in algae. So toxins, in this study, would be a secondary effect.
d. The different species of algae growing in the water . Probably this is also related to temperature and the biology of each algal species. However, the researcher is interested in a specific species of algae.
b. The temperature of the water. The temperature of THE water is directly involved in this experiment, but as the INDEPENDENT VARIABLE. The researcher will modify the temperature in order to know how it changes the algae growth. The researcher voluntarily modifies this variable, and this change provokes a change in the dependent variable.
a. The growth of the algae. The Growth of THE algae is the DEPENDENT VARIABLE. It CHANGES ACCORDING TO THE TEMPERATURE. So the change in the algae growth will depend on how the researcher modifies the temperature. We are referring to one specific algal species. This species is responsible for the toxins´ productions and is suggested to depend on temperature.

After a skeletal muscle fiber is treated with a membrane permeable drug that speeds up the action of the SR Ca 2-ATPase, how would contraction differ after multiple and frequent action potentials
Answer:
the twitch would be shorter
Explanation:
In muscle cells, the calcium (Ca2+) pump ATPase membrane transport proteins maintain a low cytosolic Ca2+ concentration in order to promote muscle contraction. Muscle relaxation occurs when the sarcoplasmic reticulum reabsorbs Ca2+ through the Ca2+-ATPase protein, thereby reducing intramuscular Ca2+ levels. In muscle contraction, intracellular Ca2+ levels are raised due to the release of Ca2+ from the sarcoplasmic reticulum (SR) via Ca2+-release channels. In consequence, it is expected that a specific drug that speeds up the action of (Ca2+) pump ATPase protein should shorten the contraction-relaxation cycle by increasing the velocity of muscle relaxation.

Role of liver in carbohydrate metabolism.
Answer:
In the metabolism of carbohydrates, the liver helps to ensure that the level of sugar in your blood (blood glucose) stays constant. If your blood sugar levels increase, for example after a meal, the liver removes sugar from blood supplied by the portal vein and stores it in the form of glycogen.
Explanation:
During exercise, epinephrine and norepinephrine are released from the adrenal medulla. Epinephrine and norepinephrine have the same effect on plasma glucose levels as glucagon. Explain how epinephrine and norepinephrine affect plasma glucose and why this is important during exercise.
Answer and explanation:
Epinephrine and norepinephrine are two hormones that are released from the adrenal medulla when the body is under stress (like during exercise, for example) as a part of the sympathetic response.
These hormones have many functions and they all work together to prepare the individual for a fight or flight response - like increasing heart rate and producing bronchodilatation. One of these functions is the rise of glucose levels in blood which is important for this substance to reach several tissues, like the skeletal muscle. The skeletal muscle will make use of this glucose to produce ATP and generate the required energy for muscle contraction through a process called glycolysis, which is key for the fight or flight response mentioned above.
When we exercise, glucose levels rise thanks to these hormones so the skeletal muscle can have enough energy to contract and move as we want. If the exercise is too intense or prolongued, glucose levels will drop and other fuels will be needed to sustain this activity, like stored glycogen and fat.

Explain how fossils, glaciers and magnetic pole wandering provide evidence that supports the theory of
plate tectonics.
Some fossils from the same species are found in different continents, across sea, these species could not swim so big distances, so it suggests that once the continents were joint and species could walk from America to Africa and other continents.
Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator, it suggests that the glaciers either formed in the middle of the ocean and/or covered most of the Earth. Today glaciers only form on land and nearer the poles, it can be suggested that glaciers were centered over the southern land mass close to the South Pole and the continents moved to their present positions afterwards.
Polar wandering is the movement of the magnetic poles over Earth’s surface through geologic time. It suggests that plates move.
The Gondwana continents glaciation could only have occurred if the continents were joined together since the centres of the glaciers would have been in the ocean if they were not. Also, the continents, such as South America and Africa are similar with jigsaw puzzle.
What plate tectonics theory?
The plate tectonics theory states that the earth is solid outer crust, the lithosphere, is segregated into plates which further move over the asthenosphere, the melted upper portion of the mantle. Oceanic and continental plates come and joined together, spread apart, and interact at boundaries all over the planet.
Similar fossil plant and animals are segregated by oceans leading to the assumption that they must have lived in adjacent regions when they were alive. Finally, similar rock sequences and mountain ranges could be connected across oceans.

PLEASE HELP ASAP!! How neurotransmitters carry nerve impulses across the synaptic cleft
Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite. The binding allows the nerve impulse to travel through the receiving neuron
Another way of thinking is
Neurons talk to each other across synapses. When an action potential reaches the presynaptic terminal, it causes neurotransmitter to be released from the neuron into the synaptic cleft, a 20–40nm gap between the presynaptic axon terminal and the postsynaptic dendrite (often a spine)
Hope this helps =)
Explanation: Neurotransmitters like to travel across the synapse between the axon and the dendrite of the next neuron. They then attach to the membrane of the dendrite. This connection makes it possible for the nerve impulse to travel through the receiving neuron.
