How do obligate aerobes and obligate anaerobes differ in their interactions with the atmosphere?
An obligate aerobe, by contrast, cannot make ATP in the absence of oxygen, and obligate anaerobes die in the presence of oxygen.
An obligate aerobe is an organism that requires oxygen to grow. Through cellular respiration, these organisms use oxygen to metabolise substances, like sugars or fats, to obtain energy. In this type of respiration, oxygen serves as the terminal electron acceptor for the electron transport chain.
An Obligate anaerobes are poisoned by oxygen, so they gather at the bottom of the tube where the oxygen concentration is lowest.
An obligate aerobe, by contrast, cannot make ATP in the absence of oxygen, and obligate anaerobes die in the presence of oxygen.

(5 points) Let’s take it one step further! Use the data chart below to answer the following question.
Light intensity (%) O2 produced (mL/h)
30 8.8
40 26.1
50 31.3
60 31.3
The data above was collected during an Elodea observation. Notice what happens to the oxygen produced at light intensities of 50% or higher. Everything has its limits, even chemical reactions! Think about a powerful race car. If you give it more fuel and better tires, it can go very fast. But, eventually, its speed will top out due to the limitations of the motor. Even if you kept adding fuel and tires, it couldn’t go any faster. Explain how the data in this experiment suggests there is a maximum photosynthetic rate. Be sure to discuss the reactants and products in your answer.
Answer:
Photosynthesis is the process by which green plants synthesize their food (sugar) from carbon dioxide and water in the presence of sunlight and chlorophyll. Oxygen is released as the byproduct of this process.
In the given experiment, the amount of oxygen produced is taken as the measure of photosynthetic rate.
The rate of photosynthesis is directly proportional to the intensity of light. However, after reaching the maximum rate increase in light intensity also fails to increase it further.
It might be because of the limitations of other factors.
In addition, further increase in light intensity can damage the photo-systems which will results in sharp decrease in photosynthetic rate.
Observations also show that even after increasing the light intensity from 50% to 60%, the oxygen production remains the same i.e. 31.3 ml/h.
The data from the experiment shows that as light intensity increases, oxygen production also increases up to a point, suggesting a maximum photosynthetic rate. Above 50% light intensity, oxygen production plateaus indicating a limiting factor in the photosynthesis process which could be related to carbon dioxide availability or the plant's photosynthetic efficiency.
Explanation:The data from the Elodea observation experiment, where light intensity and oxygen production were measured, suggests a maximum photosynthetic rate. This concept is similar to the analogy of a race car reaching its maximum speed regardless of added fuel or better tires.
For the biological process of photosynthesis, light intensity acts as 'fuel.' When light hits the chlorophyll in a plant, it energizes an electron which initiates the photosynthesis process where solar energy is converted into chemical energy that cells can use. The reactants, or 'inputs' for this process, include light and carbon dioxide. The products, or 'outputs,' include oxygen and glucose.
Looking at the data chart, the oxygen produced — a product of photosynthesis — increases as the light intensity increases up until 50%. However, above 50% light intensity, the oxygen production plateaus at 31.3 mL/h, suggesting the photosynthetic rate has reached a maximum. Similar to the race car analogy, additional light 'fuel' does not increase the oxygen 'speed,' indicating that there is a limiting factor in the photosynthesis process, potentially the amount of carbon dioxide available or the efficiency of the plant's photosynthetic system.

Which of the following is not true of negative feedback loops?
A. Negative feedback loops maintain homeostasis.
B. Negative feedback loops are temporary.
C. There are many more instances of negative feedback loops in the human body than positive feedback loops.
D.In a negative feedback loop, the response to the signal or stimulus decreases the original signal or stimulus.
The statement 'Negative feedback loops are temporary' is not true. Negative feedback loops are continuous processes that maintain stability or homeostasis in an organism by adjusting to changes and returning the system back to its optimal state.
Explanation:The option 'B. Negative feedback loops are temporary' is not true of negative feedback loops. Negative feedback loops help maintain homeostasis in an organism by ensuring that optimal conditions are maintained. They act as a self-regulating mechanism, where any deviation from the set point (ideal conditions) is corrected. For example, consider the body's temperature regulation. If your body's temperature deviates from the 37 degrees Celsius norm, mechanisms will kick into gear to either cool or heat your body back to the optimal temperature.
These processes are not temporary, but are continuous, adjusting the conditions as and when needed. Furthermore, there are indeed more instances of negative feedback loops in the human body than positive ones, given these loops work to keep a stable internal environment. Lastly, in negative feedback loops, the response to the signal or stimulus indeed decreases the original signal or stimulus, bringing the system back to its optimal state.

#SPJ12
The correct answer is B. The statement that is not true of negative feedback loops is that Negative feedback loops are temporary.
Negative feedback loops are a fundamental concept in physiology and are crucial for maintaining homeostasis within an organism. Here's a breakdown of each option:
A. Negative feedback loops maintain homeostasis.
This statement is true. Negative feedback loops are designed to counteract changes in the body's internal environment, thereby stabilizing physiological variables and maintaining homeostasis. For example, when body temperature rises, a negative feedback loop initiates sweating to cool the body down.
B. Negative feedback loops are temporary.
This statement is not true. Negative feedback loops are not temporary; they are continuously active to maintain a stable internal environment. They may be activated or deactivated as needed, but they are not temporary in the sense that they only occur once or for a limited time.
C. There are many more instances of negative feedback loops in the human body than positive feedback loops.
This statement is true. Negative feedback loops are indeed more common in the human body than positive feedback loops. Negative feedback loops are used to regulate most physiological parameters, such as body temperature, blood glucose levels, and blood pressure, among others.
D. In a negative feedback loop, the response to the signal or stimulus decreases the original signal or stimulus.
This statement is true. The defining characteristic of a negative feedback loop is that the response it generates reduces or opposes the initial stimulus. This is in contrast to positive feedback loops, where the response amplifies the initial stimulus.
Therefore, the statement that is not true of negative feedback loops is that they are temporary. Negative feedback loops are an ongoing mechanism for regulating the body's functions and maintaining stability.

An ionic bond is most likely to form between:
a)
a negatively and a positively charged ion.
c)
two uncharged atoms.
b)
two positively charged ions.
d)
two negatively charged ions.
The answer to your question is,
A) A negatively and positively charged ion.
-Mabel <3
An ionic bond is most likely to form between a negatively and a positively charged ion. This involves the transfer of electrons, resulting in opposite charges that attract each other. Option a is correct.
This type of chemical bond involves the transfer of electrons, leading to the formation of ions. Specifically, a cation (positively charged ion) and an anion (negatively charged ion) are attracted to each other due to their opposite charges, resulting in an ionic bond. For example, sodium (Na) loses an electron to become Na+, and chlorine (Cl) gains an electron to become Cl-. These ions are then attracted to each other to form NaCl, or table salt.How does the age of sea floor sediments change with increasing distance from the ocean ridge? A) their age stays the same B)their age decreases C) their age Varies without a pattern D)their age increases
D) their age increases
Answer:
Option (D)
Explanation:
In a divergent plate motion, the plates move away from one another. As a result of this, the magma comes out to the ocean floor along the mid-oceanic ridge. The new materials are added to the crust along this mid-oceanic ridge. The rocks that are present near the mid-oceanic ridge are the younger rocks as the magma after ejection cools and solidifies. With the continuous eruptions, these rocks get shifted away from this ridge. So with the increasing distance from the mid-oceanic ridge, the age of the seafloor sediments increases.
Hence, the correct answer is option (D).

What would happen if the concentration pg H+ ions were higher inside the mitochondria than outside the mitochondria when the channel opened
In mitochondria, the metabolism of sugars is completed: the pyruvate is imported ... This allows 15 times more ATP to be made than that produced by glycolysis alone. ... (A) Most of the energy would be released as heat if hydrogen were simply burned. ... and the outside positive (as a result of the net outflow of positive ions).
Answer:
The energy of proton transfer down the concentration gradient would be lost as heat and ATPs would not be formed by oxidative phosphorylation.
Explanation:
Oxidation of NADH and FADH2 via electron transport chain generates a proton motive force with intermembrane space being positive due to a higher concentration of protons as compared to the mitochondrial matrix.
Since the inner mitochondrial membrane is impermeable to protons, protons can be transported via channel proteins only. Movement of the protons down the concentration gradient via Fo proton channels drives the ATP synthesis on the matrix side.
According to the questions, the inside of the mitochondria has more protons. This would drive the movement of protons from the matrix to the intermembrane space via proton channels. Since the ATP synthase enzyme is present on the matrix side, the movement of protons towards the intermembrane space would not drive ATP synthesis and the energy will be lost as heat.

Explanation:
PLATO
Final answer:
In Mendelian genetics, according to the law of segregation, a heterozygous organism has a 50% chance of producing gametes with the recessive allele.
Explanation:
The question relates to Mendelian genetics and the inheritance patterns of alleles. According to the law of segregation, a heterozygous organism (one that has two different alleles for a trait) has a chance of producing gametes with the recessive allele. During gamete formation, alleles for a trait segregate so that each gamete carries only one allele for each gene. This results in a 50% chance of transmitting either allele to the offspring. If an organism is heterozygous for a given trait (Aa), then it has two different alleles: one dominant (A) and one recessive (a). Thus, there is a 50% chance that a gamete produced by a heterozygous organism will contain the recessive allele (a).
Therefore, the correct answers to fill in the blanks would be:
