Energy is captured during light-dependent reactions of photosynthesis (Option b).
Photosynthesis refers to the metabolic reactions that produce simple carbohydrates (e.g., glucose) by using the energy from the sun.The photosynthetic reactions can be divided into light-independent reactions and light-dependent reactions.The light-dependent reactions capture energy and light-independent reactions produce simple carbohydrates.In conclusion, energy is captured during light-dependent reactions of photosynthesis (Option b).

A current problem in modern medicine is the development of drug resistance mutations. This occurs when a mutation arises in a disease-causing microbe making it resistant to a drug and thus rendering the drug useless in treating a specific disease. Many useful drugs are competitive inhibitors of specific enzymes, and the drug-resistance mutations prevent the binding of the drug. These types of mutations, in addition to preventing competitive inhibitor binding, can also sometimes reduce the activity of the enzyme. Why is that the case?
a. Binding to the competitive inhibitor is essential for the function of the enzyme.b. These mutations most likely affect an allosteric site on the enzyme.c. These mutations lower the activation energy of the reaction catalyzed by the enzyme.d. These mutations most likely change the shape of the active site of the enzyme.
Answer:
d. These mutations most likely change the shape of the active site of the enzyme.
Explanation:
A competitive inhibitor competes with an enzyme substrate for the binding of the enzyme. When it binds, the enzyme substrate cannot bind unless the inhibitor is removed from the active site by some mechanism.
The ability of a competitive inhibitor of an enzyme to function is due to the fact that these inhibitors are structurally similar to the enzyme's substrate.
So when a mutation which also affects the activity occurs in a microbe, that renders it resistant to a drug serving as a competitive inhibitor of that enzyme in the microbe, most likely, this resistance is due to a structural change in the enzyme which changes the shape of the enzyme's active site. Therefore, both the drug as well as the enzyme's substrate, will be unable to bind to the enzymes active site.

Describe the major events in the cell cycle. Begin at G1 and follow around the cycle through M
Answer/Explanation:
The cell cycle consists of interphase and mitosis (M). Within interphase, there are three phases: G1, S, and G2.
G1 phase - the first 'gap' phase.The cell grows in size, and synthesises the necessary mRNA and proteins required to divide. This is also where the key decision as to whether the cell will divide takes place. This is based on whether or not the environmental conditions are favourable for division and whether the cell is receiving the correct signals to divide. This is called the G1/S transition, and is the critical decision making point as to whether the cell cycle will progress.
S phase - the 'synthesis' phase. The cell replicates its DNA in preparation for passing the genetic material onto the daughter cells. Once the cell's DNA is replicated, it enters G2.
G2 phase - the second 'gap' phase. The cell continues to grow in size and prepare for mitosis. There is a DNA damage checkpoint here, where the cell ensures that the DNA has properly replicated. Next, it moves into mitosis (M).
M phase - the mitosis phase. This consists of 4 stages (PMAT) - prophase, metaphase, anaphase, telophase. The cytoplasm divides during cytokinesis
During prophase the chromosomes condense and pair up. The mitotic spindle forms, and the nuclear membrane disappears. During metaphase, the chromosomes line up at the centre of the cell - at the metaphase plate. The mitotic spindles attach to the chromosomes - to each sister chromatid.During anaphase, the sister chromatids are pulled apart to opposite poles of the cellDuring telophase, two new nuclei form, surrounding the two new sets of chromosomes. Cytokinesis then occurs, pinching the membrane to create two new cells.Fasttttttttttttttttttttttttttttttt 15 points

What does age of maturity refer to?
Answer:
Coming of age, a very young person's transition from childhood to adulthood. Age of majority, the threshold of adulthood as it is conceptualized (and recognized or declared) in law. Puberty, the process of physical changes by which a child's body matures into an adult body capable of sexual reproduction.
Explanation:
Answer: The age of maturity refers to the change from childhood to adulthood.
Explanation: This means that a child is taking its first step into being an adult. Usually, this first happens during the process of puberty. Puberty occurs when you’re around 12 years of age. This is when your body starts to change into a more stronger, mature adult body.

Explanation:
Heterotrophs Meaning:
A heterotroph is an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are primary, secondary and tertiary consumers, but not producers.
Food web:
1. Hawk
2. snake
3. mouse
4.grass
suppose 10,000 units of energy are available at the level of the grasses. What is the total number of energy units lost by the time the energy reaches the hawk? How did you get your answer?
(Please help me!)
GREETINGS!
10 units of energy because in food chain the energy is lost and this energy loss is 90% at each trophic level so only 10% of energy is passed soo if grass has 10000 energy units mouse will have 1000, snake will have 100 and then hawk will have only 10 units

What is a carbon reservoir and what are some examples?
Answer:
Carbon is in a constant state of movement from place to place. It is stored in what are known as reservoirs, and it moves between these reservoirs through a variety of processes, including photosynthesis, burning fossil fuels, and simply releasing breath from the lungs.
Examples-Rocks like limestone and fossil fuels like coal and oil are storage reservoirs that contain carbon from plants and animals that lived millions of years ago.

Medical researchers often test medicines on patients who have given informed consent for the tests. The researchers divide the patients into two groups. One group is given the medicine. The second group is given a harmless substitute such as sugar pills. Neither the patients nor the researchers know which patients have received the medicine and which have received the substitute. What is the purpose of such a procedure?
to increase accuracy
to increase precision
to decrease bias
to decrease patient safety
Answer:
The correct answer is:
to decrease bias
Explanation:
This kind of experimental setup where a group of participant is given a non-medical treatment is known as a double-blinded placebo experiment. The principle of the use of a placebo is to reduce biases. Biases are influences that may affect the result of an experiment that does not arise from the effect of the treatment itself, but from some external factor. The researcher and the subject do not know which treatment is a 'sham', and which treatment is the real treatment, it helps to make approach neutral and rules out any effect of manipulations that may affect the result as a result of such knowledge.

to decrease bias

I need a sentence describing how volcanoes are created around the Ring of Fire. Using
all of these terms: convection current, subduction zone, plate boundary, oceanic plate, water, magma, and volcano.
Need Help ASAP!!
Answer:
the ring of fire was when the plate boundarys collided. this caused the oceanic plates to rise above the water. the convection and current cause the subduction zone to make a volcano and magma.
Explanation:
The ring of fire was caused by the collision of the plate boundaries. As a result, the oceanic plates moved upward, until they were above the water. Both convection and current are responsible for the formation of a volcano and magma in the subduction zone.
What is a volcano?A breach in the crust of a planetary-mass object, such as the Earth, can give rise to the formation of a volcano. This rupture makes it possible for molten lava, volcanic ash, and gases to escape from a magma chamber located under the surface. Volcanoes are most common on Earth at locations where two or more tectonic plates are moving in opposite directions, and the majority of volcanoes are found deep within the ocean.
Volcanic rock and ash make farmers' crops grow better. The volcano attracts tourists, boosting the local economy. Locals get free electricity from geothermal energy.
