Chloe is studying the effect a certain kind of fungus has on bacteria. Which of the following could be her hypothesis?
"I notice that when a certain fungus is present in a bacterial culture, the bacteria do not grow".
"Based on my tests, I realize that this fungus kills bacteria".
"I predict that the bacterial cultures in which I place this fungus will not grow".
"I propose that this fungus somehow kills bacteria."
Answer:
I propose that this fungus somehow kills bacteria
Explanation:
you rule out 2,3 because a hypotheses has not yet been proven therefore it is not certain
while in 1 in some cases the bacteria can also over power and kill the fungi using genes
but I chose 4 since fungi lack chloroplasts so they feed of ready made food and bacteria can be autotrophic therefore can manufacture food and so the fungi digests the bacteria in the process of trying to acquire the food since they don't have cell walls I guess
Your heart rate is the number of times your heart beats per minute. Heart rate differs from person to person, and it changes with activity. You can find your heart rate by taking your pulse on your wrist or neck. Lightly place your fingers on your wrist or neck and try to find your pulse. Count your pulse for 10 seconds and then multiply that number by 6 to get your heart rate for a minute. What activities do you think will increase and decrease your heart rate?
Answer:
The heart beats 100,000 times a day, is the size of your fist, and creates enough energy to drive a truck 20 miles. Yes, the heart is our hardest working and most important muscle. One of the most surefire ways to rapidly increase your heart rate is Spinning. This low impact exercise can be performed at home if you have your own bike, or in a group setting. The faster you pedal and the more resistance you face, the higher your heart rate elevates. Having gained popularity because of its low impact and low injury risk, it (not surprisingly) also improves body composition, decreases fat mass and lowers blood pressure and cholesterol. Shorter bursts of high intensity exercise have been proven to increase your heart rate more than steady, low intensity workouts. Interval training of high intensity exercise followed by a short rest period will result in both a healthier heart. For a less regimented, non-traditional workout, hiking will go a long way to ensure your heart rate is increasing steadily over a longer period of time. Hiking is a good way to improve your cardiovascular fitness, particularly if your route includes some hills, which will force your heart to work harder. Meditation activates our bodies' “rest-and-digest” functions, which counteracts our “flight-or-fight” responses. Integrating the practice into a daily routine has been linked to lower heart rate and blood pressure
Explanation:
The activities like running, swimming, cycling, jumping ropes, playing tennis, etc increase your heart rate, while the activities like deep breathing, relaxing in a silent environment with extreme calm, formal walking, relaxing exercises, etc, decreases your heart rate.
What is Heart rate?Heart rate may be defined as the number of times your heart beats or pumps in a minute with respect to your bodily activities.
Some physical activities are known to increase heart rate immediately while some of them may assist in the reduction of the heart rate significantly. Both these processes are good enough to maintain the overall condition of health prominently.
To maintain your proper cardiovascular health, it is mandatory to do more physical exercises or activities that improve your heart rate gradually.
The names of those activities are briefly mentioned above.

These screening tests are carried out in order to the medical condition of the people who are older than 50 years. These screening tests tells us about the disease in early stages. The disease can be cured if they are diagnosed in early stages so early detection of the disease plays important role in saving the life of the patient from that dangerous disease and the results are in favor of the patient. If these screening tests are not carried out earlier so the disease may cause serious damage which leads to death.
The underlined sentences demonstrate characterization. How does this technique support the author’s purpose?
Answer:
It shows how violent the situation was and how scared Enrique was.
Explanation:
The book "Enrique's Journey" by Sonia Nazario tells the true story of a young boy named Enrique on his quest to find his mother who has gone to America in search of work. The story delves into the dangerous and menacing obstacles that migrants like Enrique had to endure and go through to get to the safer land in America. This story is also like an insight into the borderlands that is between America and the South American nations, with migrants coming in masses in the hope of a better and peaceful future.
As seen in the excerpt from the book, the author provides a scene where gangsters threaten and even assault anyone who went as far as to help the authorities identify them. This very act of torturing or using violent means to keep people quiet shows how dangerous life is for the migrants while trying to get to the other side. The characterization in this passage shows the violent scene that migrants have to endure and the emotional fear that people like Enrique were put in.

(Applicable answer gets brainliest) community is located in the desert, near an area with high winds. There is very little rainfall or clouds and no large rivers nearby. The people want to build a power plant that will not pollute. They are choosing among solar, biomass, or hydroelectric power. Write one to two sentences about each of these energy sources. Describe whether each energy source would meet their goals and whether it is a good energy source for their area.
Answer:
In the given scenario, solar power would be the best and the most effective kind of power plant to be constructed in the mentioned location. This is because the generation of pollution by using solar power is negligible. Apart from this, the use of solar power plants would be the most ideal in the given community resources as the community is receiving ample amount of sunlight and the presence of less cloud cover makes the application of solar power more feasible.
If one considers biomass, then there would be the requirements of the things like crops, wood, alcohol fuels for burning so that energy can be generated, and with more than the required amount of sunlight and less or no irrigation, sources would make it hard to obtain the sources necessary for biomass power plant.
The hydroelectric energy would not even be a viable option in the given scenario as the community has no accessibility of natural water sources and the hydroelectric power concept primarily works on water storage.
Both the full body plate type and the half body plate trait are also present in an ocean near the lake. Where would you expect a higher occurrence of the full body plate trait, in the lake or the ocean? Explain your answer.
Answer:
In the ocean
Explanation:
Ecological divergence leads to selection of essential traits against migrants and hybrid species. The full body plate type traits requires attention for occurrence in an environment which is free from issues such as resource limitation or predator attacks. In vast ocean spaces , resources are not a limiting factor in ocean and also there is no risk of predators as there is huge chunk of space, thus, full body plate type will occur in higher number in the ocean.

The given question is incomplete, the complete question is:
Madison lives near the ocean. She’s formed a hypothesis that increased concentrations of salt in the air speeds the corrosion of certain metals. If Madison plans to test this hypothesis, she will have to deal with the following variables in her experiment: dependent variable: independent variable: one possible confounding variable:
Answer:
A variable, which is under study or observation in an experiment and changes concerning the independent variable is termed as a dependent variable. Based on the given experiment, Madison is checking the influence on the progression of corrosion of metals concerning the variations in the concentration of salt. This shows that the extent of corrosion of metals is a dependent variable.
A variable, which can be controlled or monitored like increased or decreased, and one is familiar with is termed as an independent variable. This variable is not affected by another variable, like a change in the concentration of salt is the air may exhibit an effect on the corrosion of the metal, however, the process that is, the corrosion of metals does not affect the concentration of salt in the air. Hence, the independent variable is the salt concentration in air.
A variable that possesses the tendency to change or influence both the independent and dependent variables is known as a confounding variable. If the airspeed is higher than it will carry the salt particles at a brisk rate and speed resulting in enhanced corrosion of metals. Likewise, if the speed of air is slower, there will be a reduction in the corrosion of metals. Hence, the confounding variable is the speed of air.

One primary advantage of light microscopy over electron microscopy is that ________. light microscopy provides higher contrast than electron microscopy light microscopy provides for higher magnification than electron microscopy light microscopy allows the visualization of dynamic processes in living cells light microscopy provides for higher resolution than electron microscopy
Answer:
light microscopy allows the visualization of dynamic processes in living cells light
Explanation:
Light microscopy has a biggest advantage over electron microscopy because it all the visualisation or ability to observe living cells and biological activity such as the uptake of food, cell division and movement. Light microscopy can be use in-vivo staining techniques to visualise the uptake of colored pigments by the cells which cannot be observed with electron microscopy because in electron microscopy the element must be fixed, dehydrated or dead before been visualised . Electron microscope cannot observe living cells and can only observe dead or dry specimens so that electrons can pass through the specimen to be able to observe.
Light microscope has higher penetrating power than electron microscopy thus allows the visualization of dynamic processes in living cells. Therefore, option c is correct.
Microscopy is the technical field of using microscopes to view samples & objects that cannot be seen with the unaided eye.
Light microscopes can also be used to visualize dynamic processes in living cells because it has greater penetrating power than electron. Electron microscopes uses high-energy electrons that would damage the cells.
Electrons have shorter wavelength than visible light, so provide higher resolution than light microscopes.
Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.

Why is the citric acid cycle a cyclic pathway rather than a linear pathway?
In the oxidation of pyruvate to acetyl CoA, one carbon atom is released as CO2. However, the oxidation of the remaining two carbon atoms—in acetate—to CO2 requires a complex, eight-step pathway—the citric acid cycle. Consider four possible explanations for why the last two carbons in acetate are converted to CO2 in a complex cyclic pathway rather than through a simple, linear reaction.
Use your knowledge of the first three stages of cellular respiration to determine which explanation is correct.
The given question is incomplete as the four possible explanations or options are not provided, however, the correct options are as follows:
A) More ATP is produced per CO2 released in cyclic processes than in linear processes.
B) It is easier to remove electrons and produce CO2 from compounds with three or more carbon atoms than from a two-carbon compound such as acetyl CoA.
C) Redox reactions that simultaneously produce CO2 and NADH occur only in cyclic processes.
D) Cyclic processes, such as the citric acid cycle, require a different mechanism of ATP synthesis than linear processes, such as glycolysis.
Answer:
The correct answer would be - option B
Explanation:
Circular pathways or the cycles are able to carry out two or more than two entry and exit points for the substrate enzyme and products, So it is well suited for amphibolic reactions.
In a linear pathway, one reaction with particular substrate or reactants and result in products through the pathway completes the pathway, and the second reaction would be an independent event.
In citric acid cycle It is easier to eliminate electrons and gain carbon dioxide from compounds with 3 carbon or more carbon atoms than from a two-carbon compound such as acetyl CoA. pyruvate is 3 C compound while acetyl CoA is two carbon.
Thus, the correct answer is - option B
