Ferredoxin transfer an electron to nadp. Through Fe-S clusters whose iron cations swing between +2 (ferrous) oxidation states and +3, the iron-sulfur protein ferredoxin facilitates electron transport in a vast variety of redox processes in cellular metabolism (ferric).

From the anaerobic bacterium Clostridium pasteurianum, the first protein of this kind was identified in 1962. The cyclic and noncyclic photophosphorylation processes of photosynthesis are mediated by a ferredoxin peculiar to chloroplasts. Ferredoxin-NADP + reductase (EC 1.18.1.2) lowers NADP + with FAD and a flavin group as cofactors, and ferredoxin serves as the final electron acceptor in non-cyclic photophosphorylation:

When the level of carbon dioxide increases in the atmosphere, the level of CO2 also increases in the oceanic ecosystem due to absorption.

An ecosystem may be characterized as a place or an area where individuals of different species live together and interact with one another for the purpose of food, shelter, space, and mating partner.

An ecosystem of the ocean absorbs about 30% of the carbon dioxide that is released into the atmosphere. As levels of atmospheric CO2 increase from human activity such as burning fossil fuels (e.g., car emissions) and changing land use (e.g., deforestation), the amount of carbon dioxide absorbed by the ocean also increases.

Therefore, the amount of carbon dioxide in the atmosphere is directly related to the amount of carbon dioxide in the ocean.

Answer:

the answer is b.

Explanation:

human somatic cells are diploid

The statement "b. They are haploid" is not true about human somatic cells.

Human somatic cells are the non-reproductive cells that make up the body tissues and organs. They are diploid, meaning they contain two sets of chromosomes, one set inherited from each parent. The correct answer is option b, "They are haploid," which means having only one set of chromosomes.

In humans, somatic cells contain 23 pairs of chromosomes, for a total of 46 chromosomes. These chromosomes are organized into homologous pairs, where one member of each pair is inherited from the mother and the other from the father. This diploid chromosome number ensures that somatic cells contain the full complement of genetic information necessary for normal cellular function and development.

Somatic cells reproduce by mitosis, which is a type of cell division that results in two identical daughter cells with the same number of chromosomes as the parent cell. Mitosis allows somatic cells to grow, replace damaged or worn-out cells, and maintain the overall structure and functioning of the body.

In comparison to bacterial cells, human somatic cells are more complex. Human cells have a nucleus containing genetic material (DNA), membrane-bound organelles (such as mitochondria and endoplasmic reticulum), and a complex cellular structure. Bacterial cells, on the other hand, lack a nucleus and membrane-bound organelles, and they have a simpler cellular organization.

Therefore, the statement that is not true about human somatic cells is option b, "They are haploid." Human somatic cells are diploid, containing two sets of chromosomes.

The Pre-australopithecines, also known as Ardipithecus, has been a recent area of interest in the study of human evolution. The species, which lived between 4.4 and 6 million years ago, is characterized by a combination of primitive and advanced features that distinguish them from other species, including Australopithecus and Homo. Their unique anatomical traits and the environmental context in which they lived force us to rethink the Savanna hypothesis.

Ardipithecus lived in a woodland environment, which is quite different from the savanna environment that the Savanna hypothesis proposes as the main driving force for human evolution. These environments are fundamentally different from each other, with different ecological constraints and selective pressures. Ardipithecus had anatomical traits that differ from the expectations of the Savanna hypothesis, including a lack of adaptations for efficient bipedalism and running. Their feet had grasping toes that could grasp onto branches, suggesting that they lived in trees, while their legs were adapted for walking upright, indicating that they could walk on two legs.

These adaptations suggest that the pre-australopithecines were more adapted to a climbing lifestyle than a running one, which challenges the view that bipedalism and running were the main driving force for human evolution. As a result, we need to rethink the Savanna hypothesis and consider alternative theories that account for these anatomical traits and environmental contexts. In conclusion, the unique anatomical traits and environmental context of Ardipithecus force us to rethink the Savanna hypothesis.

If you were asking something else please coment.

The plant metabolism is a complex process that requires the coordination of multiple cellular pathways, including photosynthesis and respiration, for the optimal growth and survival of the organism.

A plant cell's primary energy currency is adenosine triphosphate (ATP), which is generated by the enzyme ATP synthase through the process of oxidative phosphorylation, which occurs in the mitochondria. This ATP provides the energy required for the plant to carry out its metabolic processes. However, if a plant is infected with a virus that blocks ATP synthase's enzyme, it cannot produce ATP, and hence, its metabolism and growth are affected.

Nonetheless, the Calvin Cycle is still capable of producing glyceraldehyde 3-phosphate (G3P), even if ATP synthesis is blocked by a virus. Calvin cycle is a biochemical pathway of photosynthesis in which carbon dioxide is converted into organic compounds, with the help of light energy, by the plant's chloroplasts. During the Calvin cycle, carbon dioxide combines with ribulose-1, 5-bisphosphate (RuBP) to form two molecules of 3-phosphoglycerate, which are converted to glyceraldehyde 3-phosphate (G3P) by utilizing energy and reducing power from ATP and NADPH, respectively, which are generated during the light-dependent reactions. These G3P molecules are used to synthesize glucose, starch, and other organic compounds, which provide energy to the plant. In conclusion, the plant's ability to produce G3P by the Calvin cycle, even if the ATP synthase enzyme is blocked, can help the plant to survive and grow under stress conditions like viral infection.

The scientific explanation for how life on Earth has changed over time, from its beginnings to the enormous diversity of living organisms we observe now, is the idea of evolution.

The theory is supported by evidence gathered over many years by researchers in numerous disciplines of study, including observations of live species, fossilized remains of extinct species, and a variety of other findings.

Early theories of evolution extend back to ancient Greece, but it wasn't until the 19th century that Charles Darwin and Alfred Russel Wallace put out the theory of evolution based on natural selection. Since then, research in areas like molecular biology, embryology, geology, and fossils has produced compelling evidence in favor of evolution.

The fossil record, which demonstrates the gradual changes in species over time, comparative anatomy and embryology, which highlight the similarities and differences between species, and molecular biology, which demonstrates the genetic relationships between various organisms are some examples of evidence for evolution.
