After photons strike the light absorbing pigment chlorophyll, which of the following occurs
first?
O
Electrons in water get released during photolysis
O
Electrons are transported into the electron transport ch
O
ATP is transformed into glucose.
Electrons in chlorophyll become excited.
:)))
Answer:
Electrons become excited
Explanation:
After photons strike the light-absorbing pigment chlorophyll, electrons within the chlorophyll become increasingly excited. Only after this initial excitation do the electrons begin getting transported into the electron transport chain. Electrons in water molecules get released during photolysis, but only after they first become excited. ATP isn’t transformed into glucose until the light-independent stages of photosynthesis.
After photons strike the light absorbing pigment chlorophyll, the electron in that molecule becomes excited. The correct option is D.
What is chlorophyll?Chlorophyll is the term coined to the green pigment used by plants to produce food throughout the photosynthesis process.
Chloroplasts are plant cell organelles that use photosynthetic energy to revert light energy into fairly stable chemical energy.
They endure life on Earth while doing so. Chloroplasts also perform a variety of metabolic functions for plant cells, such as the metabolism of fats and membrane lipids.
Chlorophyll is excited and emits electrons when it absorbs light. These chlorophylls are discovered in photosynthetic units known as Photosystems I and II.
Each unit has a distinct reaction center containing pigment molecules. These molecules absorb different wavelengths of light and emit electrons.
Thus, the correct option is D.

In figure 33-5, identify the four chambers of the heart. then use them to describe the path through which blood travels in the heart.
Answer:
You did not provide a figure, but you can refer to the attached picture and match it up with your figure.
The heart has 4 chambers. It has the left and right Atrium (plural is atria) and the left and right ventricle.
The blood FROM the body going towards the heart is deoxygenated. It empties into the RIGHT ATRIUM. From there, it goes through the tricuspid valve then empties into the RIGHT VENTRICLE. The right ventricle then pumps the blood up into the pulomonary artery, and goes towads the lungs to be oxygenated. The oxygenated blood then leaves the lungs via the pumonary vein and it empties the blood into the LEFT ATRIUM. From there the blood goes through the bicuspid valve and pours into the LEFT VENTRICLE. The left ventricle pumps the blood up the aorta and from there, it goes to the different parts of the body.
In summary:
BODY ---> RIGHT ATRIUM ---> RIGHT VENTRICLE ---> LEFT ATRIUM ---> LEFT VENTRICLE
Take note though that this is the pathway with regards to ONLY the chambers.

happy to help again :)
Answer:
The correct answer is option B (negative gravitropism) and option C (positive phototropism).
Explanation:
Plant seedlings shows downward growth of roots and upward growth of stems due to response of plants to external environmental stimulus via a phenomemon known as tropism.
Plant tropisms are the result of differential growth as cells in area of stem or root grows more quickly than cells in opposite area.this growth determines the directional growth of the entire plants. The directional growth of an organism in response to light is known as Phototropism while directional growth of an organism in response to gravity is known as gravitropism.
Shoot growth in plants shows negative geotropism because they grow away from that force or in opposite direction of the gravity. Also, plants shows positive phototropism as they respond in direction of light.
Thus, option B (negative gravitropism) and option C (positive phototropism) are the right answer.

Describe each method of asexual reproduction:
Fission:
Budding:
Fragmentation:
Fission : fission the process where eukaryote cells replicate their DNA and create a new organism with a copy of that DNA.
Budding : a new organism develops from an outgrowth or bud due to cell division. The new organism remains attached as it grows, separating from the parent organism only when it is mature
Fragmentation : an organism is split into fragments. Each of these fragments develop into matured, fully grown individuals that are identical to their parents.
Hope this helps , Danielle xo
Fission is defined as the splitting of a single cell organism into two or more separate daughter cells.
What are the types of fission?Binary fission is of two kinds: Binary fission and multiple fission. Binary fission is most common form of reproduction in that occurs in some single-celled eukaryotes and prokaryotes. For example, amoeba.
Multiple fission is defined as when the organism divides equally into more than two different parts and they develop to form New individuals.
Budding is defined as the formation of an outgrowth (bud) from an organism. Bacteria, yeast, flatworms are the examples of budding.
Fragmentation is a type of cloning where one organism is divided into minor fragments. Once divided, the fragments develop into individual ones which are fully grown.

To make a 25% sugar syrup, we need to determine the amount of water required to dissolve the sugar.
We know that we have 50 grams of sugar, and we want the sugar to be 25% of the total mixture. This means that the remaining 75% will be water.
Let's set up an equation to find the amount of water needed:
Sugar + Water = Total Mixture
50g + Water = Total Mixture
Since we want the sugar to be 25% of the total mixture, we can express it as a decimal fraction:
25% = 0.25
Now we can rewrite the equation as:
50g + 0.25(Total Mixture) = Total Mixture
Next, we want to solve for the amount of water needed. To do this, we'll isolate the Water term:
0.25(Total Mixture) = Total Mixture - 50g
0.25(Total Mixture) - Total Mixture = -50g
0.25(Total Mixture) - 1(Total Mixture) = -50g
-0.75(Total Mixture) = -50g
Dividing both sides by -0.75:
Total Mixture = -50g / -0.75
Total Mixture ≈ 66.67g
Now, to find the amount of water needed, we'll subtract the weight of the sugar from the total mixture:
Water = Total Mixture - Sugar
Water = 66.67g - 50g
Water ≈ 16.67g
Therefore, to make a 25% sugar syrup with 50g of sugar, you would need approximately 16.67g of water.
The two waves in the diagram are occupying the same place at the same time
Answer: by adding the amplitude of the two waves
Explanation:
The question pertains to wave superposition in Physics, demonstrating constructive interference and standing waves when two identical waves intersect in opposite directions, leading to an increase in amplitude and fixed points of no motion (nodes) and maximum motion (antinodes).
The question deals with the concept of wave superposition in Physics, specifically the phenomena known as constructive interference and standing waves, which occur when two waves occupy the same place at the same time.
When two identical waves traveling in opposite directions intersect, they can add up at the same points in space, leading to an increase in amplitude. This process is called constructive interference, resulting in wave patterns called standing waves, characterized by their nodes—points where the amplitude is always zero—and antinodes—points of maximum amplitude. The figures mentioned in the question demonstrate these phenomena. For example, Figure 16.33 illustrates pure constructive interference where the amplitude of the resulting wave is twice that of the individual waves due to their perfect alignment in phase, whereas Figures like 12.1.1 and 5.6.5 show standing wave patterns resulting from the superposition.

A single pair of goldfish in a aquarium produced a large number of offspring.
These offspring showed variations in body shape and coloration.
The most likely explanation for these variations is what?
(A.) Offspring were adapting to different environments.
(B.) Parent fish had not been exposed to mutagenic agents.
(C.) Offspring were produced from different combinations of genes.
Answer:
C. Offspring were produced from different combinations of genes.
Explanation:
The offspring would not be adapting to different environments as they all live in the same aquarium. There is no mention of mutagenic agents present in the aquarium and that would have had more of an effect on the parents and not the offspring. The parents may have had different sets of alleles which could produce a variety of phenotypes of their offspring.
