Answer: a change in energy state occurs. The answer is dark or opaque - not able to be seen through.

Explanation:

The absorption of light makes an object dark or opaque to the wavelengths or colors of the incoming wave: Wood is opaque to visible light. Some materials are opaque to some wavelengths of light, but transparent to others. Glass and water are opaque to ultraviolet light, but transparent to visible light.

Answer:

When properly stimulated, electrons in these materials move from a lower level of energy up to a higher level of energy and occupy a different orbital. Then, at some point, these higher energy electrons give up their "extra" energy in the form of a photon of light, and fall back down to their original energy level.

ATP and NADPH serve as key molecules that connect the light-dependent and light-independent reactions in photosynthesis. They play crucial roles in transferring energy and reducing power between the two processes, ensuring the overall efficiency of photosynthesis.

1. Light-Dependent Reactions: These reactions occur in the thylakoid membranes of the chloroplasts and convert light energy into chemical energy. During this process, light energy is absorbed by chlorophyll and other pigments, leading to the generation of ATP and NADPH.

2. ATP Generation: The absorbed light energy is used to power the electron transport chain, which pumps protons across the thylakoid membrane, creating a proton gradient. The flow of protons back across the membrane through ATP synthase generates ATP from ADP and inorganic phosphate.

3. NADPH Generation: Simultaneously, the energized electrons from the electron transport chain are transferred to NADP+, reducing it to NADPH. This process requires the input of high-energy electrons and protons.

4. Light-Independent Reactions (Calvin Cycle): ATP and NADPH generated during the light-dependent reactions are utilized in the stroma of the chloroplasts to fuel the Calvin cycle. Here, carbon dioxide is fixed and converted into glucose through a series of enzymatic reactions.

5. ATP Utilization: ATP provides the necessary energy to power the various enzyme-catalyzed reactions in the Calvin cycle. It is used to drive the carboxylation of ribulose bisphosphate (RuBP), the regeneration of RuBP, and other key steps in the cycle.

6. NADPH Utilization: NADPH functions as a reducing agent in the Calvin cycle, providing the necessary high-energy electrons to convert carbon dioxide into glucose. It acts as a source of electrons in the reduction of 3-phosphoglycerate to glyceraldehyde 3-phosphate (G3P).

7. Recycling of ADP, NADP+, and Pi: As ATP is hydrolyzed to ADP and inorganic phosphate (Pi) during the Calvin cycle, ADP and Pi are regenerated in the light-dependent reactions. Similarly, NADP+ is regenerated from NADPH.

8. Continuous Cycle: The production of ATP and NADPH in the light-dependent reactions and their utilization in the light-independent reactions create a continuous cycle, ensuring the flow of energy and reducing power required for photosynthesis.

In summary, ATP and NADPH act as energy and reducing power carriers, respectively, connecting the light-dependent reactions that capture light energy with the light-independent reactions that utilize this energy to produce glucose. Their continuous generation and utilization ensure the efficiency and functionality of photosynthesis.

Answer:

O C. There is no photosynthesis.

Explanation:

Aphotic zone of a body of water refers to the part where almost no sunlight. With this condition of water, marine life is limited to species who does not light for survival. The aphotic area also is the basin of the dead organism that submerges from the photic part. Temperatures at these areas are also low

In an aphotic zone of a body of water, there is no photosynthesis present (option C), as the aphotic zone is the portion of the body of water that receives little to no sunlight and therefore does not support photosynthesis.

The aphotic zone is the deep layer of a body of water that is not reached by sunlight. As a result, there is no photosynthesis in this zone, and plants cannot grow here. Since photosynthesis is the primary means of producing food and energy in most aquatic ecosystems, organisms in the aphotic zone have to rely on alternative sources of energy. In the aphotic zone, organic matter such as dead plants and animals that sink down from the photic zone provide a source of energy for organisms.

Hence, in an aphotic zone of a body of water, there is no photosynthesis present in option C.

Explanation:

i think thats why

Answer:

Leaves float on water since they are too lightweight to break the surface tension of the water. Leaves also contain chloroplasts; which makes sugars using sunlight (a.k.a. photosynthesis). One of the by-products of this process is Oxygen. The oxygen sits in the middle of the leaf, called the Parenchyma. This gives the leaf a lower density than water; thus causing it to float.

The organelle marked with an X in the given options is the mitochondrion.

The correct answer would be mitochondrion.

Mitochondria are double-membraned organelles found in most eukaryotic cells. They play a crucial role in cellular respiration, which is the process of converting nutrients into usable energy in the form of adenosine triphosphate (ATP).

Mitochondria are often referred to as the "powerhouses" of the cell because they produce the majority of ATP required for cellular activities. They contain their own DNA and ribosomes, enabling them to partially control their own protein synthesis. The inner membrane of mitochondria is highly folded into structures called cristae, which increase the surface area available for energy production.

Mitochondria are involved in several metabolic processes, including the citric acid cycle and oxidative phosphorylation. During these processes, they utilize oxygen to break down carbohydrates, fats, and proteins, releasing energy that is used to generate ATP. This energy is essential for various cellular activities, such as muscle contraction, active transport, and synthesis of macromolecules.

Mitochondria also have other important functions in the cell. They participate in calcium signaling, regulate cell death through apoptosis, and are involved in the synthesis of certain molecules required for cellular function.

In summary, the organelle marked with an X is the mitochondrion. It is a vital organelle involved in cellular respiration and ATP production, often referred to as the "powerhouse" of the cell. Mitochondria have their own DNA, ribosomes, and a highly folded inner membrane, and they play critical roles in energy metabolism and other cellular processes

Answer:

Read a Material Safety Data Sheet (MSDS).

Explanation:

It will take an airplane 3 hours to fly 900 kilometers at a speed of 300 kilometres an hour.

An object's entire velocity, independent of velocity, is its distance. Independent of where someone started or ended, km is the extent of land that only an object is spanned. Without using a time unit, the distance can be calculated using the expression v2 = 2ad, where pro is the inverse of the speed and an is the impulse of the skin.

Distance is how length is calculated. For instance, a road's length is equal to its length. The metric system uses the following units of measurement:

Briefing:

time = distance ÷ speed,

distance ⇒ 900

speed ⇒ 300

time⇒ 900÷300

Since genes D and E are said to assort independently, we can assume that they are on different chromosomes and therefore not linked.

To solve this problem, we need to first determine the genotypes of the F1 females. Since all of the F1 females were wild-type, we know that they must have had at least one dominant allele for each of the three traits: wild-type eye (cn+), normal wings (vg+), and normal body (rf+).

We can represent the genotype of the F1 females as follows: cn+ vg+ rf+/cn+ vg+ rf+. When these females were test-crossed with homozygous recessive males (cn cn vg vg rf rf), we observed the following offspring:

Cinnabar vestigial (cn vg): 382

Roof (rf): 401

Cinnabar (cn): 3

Roof vestigial (rf vg): 4

Cinnabar vestigial roof (cn vg rf): 59

Wild-type (cn+ vg+ rf+): 67

Cinnabar roof (cn rf): 44

Vestigial (vg): 40

We can use these numbers to calculate the recombination frequency (RF) between each pair of loci using the formula: RF = (number of recombinant offspring / total number of offspring) x 100%.

RF between cn and vg:

Recombinant offspring = cn vg + cn + cn vg rf + cn rf = 382 + 3 + 4 + 44 = 433

Total offspring = 382 + 401 + 3 + 4 + 59 + 67 + 44 + 40 = 1000

RF = (433/1000) x 100% = 43.3%

RF between vg and rf:

Recombinant offspring = cn vg rf + cn+ vg+ rf+ = 59 + 67 = 126

Total offspring = 382 + 401 + 3 + 4 + 59 + 67 + 44 + 40 = 1000

RF = (126/1000) x 100% = 12.6%

RF between cn and rf:

Recombinant offspring = cn rf + cn+ vg+ rf+ = 44 + 67 = 111

Total offspring = 382 + 401 + 3 + 4 + 59 + 67 + 44 + 40 = 1000

RF = (111/1000) x 100% = 11.1%

Now we can use these recombination frequencies to construct a genetic map:

cn -- 43.3 mu -- vg -- 12.6 mu -- rf

Answer:

Low; high.

Explanation:

A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.

Basically, a microscope is used for viewing very little objects, microorganisms and cells found in living organisms such as humans, animals and plants.

The interchangeable lenses found in a microscope which are close to the specimen being observed are called objective lenses. These objective lenses comprises of low power objective and high power objective. To see a general view of a microscope slide, use low power. If you need to see a more specific and detailed view, use high power.

Hence, the field of view (FOV) is largely dependent on the objective lens being used, it is largest (general view) for low power and smallest (specific and detailed view) for high power.

Let's recall what Charles Darwin found:

He stated that natural selection plays a huge role in evolution. He claimed that organisms that had the best traits well-adapted for their specific ecosystem would be able to survive the longest (the most fitness and also known as "survival of the fittest").

Also recall what happens in an ecosystem and food webs as well as the logistical growth equation:

Ecosystems have only so many amounts of resources, or limited resources. Therefore, organisms within the same ecosystem will compete for these resources. These organisms will struggle and fight to survive. They either adapt or they get killed off.

Therefore, the best answer choice that doesn't describe Darwin's statements about evolution is answer choice D.

The correct option is B ; The transfer RNA anticodon binds to the messenger RNA codon. During translation, ribosomal subunits form a sandwich on the strand of mRNA,

where they bind tRNA molecules bound to amino acids (circles). As the ribosome decodes the mRNA sequence into a polypeptide, or new protein, a lengthy chain of amino acids appears.

The tRNA that has lost an amino acid is freed. It can then attach to another amino acid molecule and be reused later in the protein-making process. The ribosome advances the mRNA three nucleotides at a time via a ratcheting process.
