Water in the chloroplast acts as a reducing agent which provides H⁺ ions that convert NADP to NADPH which is then utilized in Krebs cycle. NADPH is an important reducing agent present in chloroplasts.
What is Photosynthesis?Photosynthesis is the process by which plants prepare their own food with the help of sunlight which is trapped in the chlorophyll molecules present in the chloroplast. Chloroplast contains different pigments which include chlorophyll a, b, and accessory pigments.
Chlorophyll b absorbs mostly the blue and yellow colored light with less intensity. This reflects green-colored light which makes the plant look green.
Anthocyanin is an accessory pigment. These are water-soluble vacuole pigments which looks red, purple, blue, or black depending on the pH.
Chlorophyll a has the maximal absorption in the red light region with 642 nm and in the blue region with 372 nm. Whereas, chlorophyll b has the absorption maximum values 626 nm and 392 nm, respectively.
The leaf with the green color will show the lowest amount of starch in it. This is because plants absorb blue and red light more than the green light which will affect the photosynthesis rate. Therefore, less amount of starch is produced.

Usually during axial muscle contraction, the more moveable muscle attachment, the ______ attachment is pulled toward the less moveable muscle attachment.
Answers
Every skeletal muscle in the human body is connected to a bone or other connective tissue structure, and each one crosses at least one joint. Typically, we describe muscle attachments by identifying their origin and insertion point.
The origin is the point at which the muscle attaches to an immovable or less movable bone - the point at which the muscle is anchored to the bone. The insertion is the point at which the muscle attaches to the movable bone. When a muscle contracts, the insertion is typically pulled towards the origin, resulting in movement.
Some muscles cross more than two joints, making their action more complicated. Depending on the action, other muscles have interchangeable origins and insertions. As a result, it is critical to consider the type of movement a muscle can perform when describing it.

Answers
The locations for three genes have been added to this cartoon. For clarity, the locations have only been noted on one chromatid. The lowest frequency of crossovers would occur between genes a and b.
What are chromatids?
A chromatid is known as one of the two identical halves of a chromosome that has been replicated in preparation for cell division. There are normally two “sister” chromatids which are joined at a constricted region of the chromosome called the centromere but during the anaphase stage of a cell division, They get torn apart and they are distributed among the cytoplasm of each daughter cell.
A vast quantity of DNA that is arranged physically into a single structure is called a "chromosome." Because of this, the "sister chromatids" are regarded as being separate chromosomes even though they are joined together. Each chromatid is thought to be its own chromosome once they are divided during anaphase.

Answers
Compared to the tropical rainforests, the temperate rainforests generally have more broad-leaf trees.
In general, temperate rainforests have more broad-leaf trees than tropical rainforests do. It is as a result of the rainforest's significantly lower average temperature as compared to tropical rainforests.
In order to create distinct layers of vegetation, groups of plants with identical size and life form are referred to as synechiae. Synechiae can be found in greater numbers in tropical rainforests than in other types of ecosystems. They comprise both mechanically dependent synechiae, such as climbers, stranglers, epiphytes, and parasitic plants, as well as mechanically independent species, whose stems are self-supporting. The tropical rainforest contains a unique assortment of different-sized trees, and these trees create numerous canopies beneath the top layer, albeit they are not usually easily distinguishable as distinct layers.

Answers
The correct answer is . all amino acids are specified by more than one codon.
What is genetic code?
The phrase "genetic code" refers to a gene's instructions to a cell on how to make a specific protein. The four nucleotide bases of DNA, adenine (A), cytosine (C), guanine (G), and thymine (T), are employed in various ways by each gene's code to form three-letter "codons" that specify which amino acid is necessary at each position within a protein.
Genetic material the history of the genetic code relates the hopes and dangers of biology and genetics throughout the 19th, 20th, and 21st centuries. For instance, Oswald Avery put an end to more than 80 years of fruitful conjecture in 1944 when he demonstrated that the genetic code—that is, DNA—was in fact the carrier of hereditary information. However, despite how crucial DNA was to the so-called heroic era of molecular biology, which covered the generation of scientific advancement following World War II, and how crucial DNA is to the ground-breaking sciences of genetics and genomics, neither genes nor DNA can determine who you are or what you will do.

A student placed two samples of tissue in pure water. One was an animal sample, and the second was plant tissue.
What are the results the student will have after 48 hours have passed?
Answers
When placed in a solution with a high concentration of water relative to its contents such as pure water red blood cells absorb water by osmosis swelling and rupture. Water diffuses from a high extracellular water concentration to a low intracellular water concentration.
The cell contents cytoplasm and vacuoles press against the cell wall, causing the cell to swell. Fully swollen cells support the non-lignified plant stem. In more concentrated solutions with low water potential, the cell contents lose water by osmosis. They contract and move away from the cell wall.
There is no net movement of the water when cells are held in an isotonic solution with the same water concentration as the cells. So the correct answer is option A. When the solution moves from the outside to the inside this is called osmosis. Cell rupture can occur due to excess water inside the cell. It acquires water by osmosis and swells until the cytoplasm and cell membrane are pressed against the cell wall. they should be swollen.

in using the muscle control formula, if the effect of the external force is in the same direction as the actual movement, what is the next thing to determine?
Answers
The movement's speed must be established. A step-by-step process for identifying the participating muscles and their action for any joint movement is provided by the muscle control formula that follows.
At first sight, this muscle control formula could seem a little difficult and complicated. But with some practise, you ought to be able to do it quickly. Once the technique is automatic and instinctual (after enough practise), you will be able to analyse movements without thinking about each step in the method. However, until you acquire these movement analysis instincts, using the muscle control formula is helpful. We state the issue before introducing the muscle control formula: Describe the name of the movement (or position), the plane of movement, the impact of the external force acting on the system, the type of muscle action (e.g., shortening or concentric, lengthening or eccentric, or isometric), and the muscles involved in the movement (or position), given a specific joint movement (or position).

Why do you think we know very little about the mantle

We know very little about the mantle because-
For humans, creating a picture of the mantle is very challenging. It is difficult to send a robotic or human mission to the mantle (Earth's core) to observe and gather additional evidence in order to further our understanding of its existence because of the mantle's extreme temperature.
What is Mantle?A mantle is a layer inside a planetary body bordered below by a core and above by a crust. Typically the thickest and most massive layer of a planetary body, mantles are composed of rock or ice. Planetary bodies that have undergone differentiation by density are known to have mantles. Mantles are found on all planetary moons, all terrestrial planets (including Earth), and a number of asteroids. Silicate rock makes up the Earth's mantle, which lies between the crust and the outer core. Its 4.01 x 1024 kg mass is 67% that of the Earth. It makes up about 84% of the Earth's volume and has a thickness of 2,900 km (1,800 mi). Although it is mostly solid, in geological time it behaves like a viscous fluid.
