Answer:
1) Sun
2) Photosynthetic process
3) Chemical
4) NADPH
5) Oxygen and Hydrogen electrons
Explanation:
1) Photosynthesis is the process by which plants convert energy from the sun. It is the process that allows plants to create organic molecules that they use as fuel.
2) Specifically, plants use energy from sunlight to react carbon dioxide and water to produce sugar (glucose) and oxygen. Oxygen is also written as O[tex]_{2}[/tex].
3) the light-dependent reactions involve a series of chemical conversions.
Many reactions occur, but the overall chemical reaction for photosynthesis is: 6 CO2 + 6 H2O + light → C6H12O6 + 6 O.
That is Carbon Dioxide + Water + Light is converted to Glucose + Oxygen.
4) an electron carrier called NADPH drives the light-independent reactions. The full meaning of NADPH nicotinamide adenine dinucleotide phosphate hydrogen. NADPH is a produced during the first stage of photosynthesis and is used to catalyse the reactions that take place in the second stage of photosynthesis.
5) In photosynthesis, the light-dependent reaction uses light energy from the sun to split water (photolysis). Water, when broken down creates oxygen, hydrogen, and electrons.

Photosynthesis converts light energy into chemical energy in plants, producing ATP and NADPH in light-dependent reactions. These energy carriers drive the Calvin cycle in light-independent reactions, creating organic sugar molecules from CO₂. Water provides the electrons needed for the light-dependent reactions.
Explanation:Plants use the process of photosynthesis to make organic molecules. Oxygen (O₂) is an essential product of the light-dependent reactions. These reactions involve a series of energy conversions in which sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy in the form of ATP and NADPH. An electron carrier called NADPH drives the light-independent reactions, also known as the Calvin cycle. Here, the ATP and NADPH produced in the light-dependent reactions are used to fix CO₂ into organic sugar molecules. Water (H₂O) provides electrons for the light-dependent reactions, with photosystem II initiating photosynthesis through the absorption of a photon

What is a likely evolutionary advantage of sexual reproduction over asexual reproduction? a sexual reproduction involves fewer steps. b there is a lower chance of using up the resources in a given environment. c sexual reproduction results in variation in the offspring. d sexual reproduction is more costeffective?
The primary evolutionary advantage of sexual reproduction over asexual reproduction is that it results in increased genetic diversity, providing advantages in changing environmental conditions.
Explanation:The most likely evolutionary advantage of sexual reproduction over asexual reproduction is the fact that sexual reproduction results in genetic diversity or variation among offspring. This variation allows populations to adapt to changing environments more quickly because it increases the probability that some individuals will have characteristics suited to the new conditions, thereby allowing the species to survive and reproduce. This contrasts with asexual reproduction, which results in offspring that are exact clones of the parent, thus less able to survive changes in the environment.

What is the primary function of the calvin cycle of photosynthesis?
The Calvin cycle is a crucial part of photosynthesis that converts atmospheric carbon dioxide into carbohydrates using ATP and NADPH, thereby storing energy from sunlight in a form that the plant can use for growth.
Explanation:The primary function of the Calvin cycle in photosynthesis is to convert carbon dioxide from the atmosphere into carbohydrates. This process, also known as carbon fixation, occurs in the stroma of the chloroplasts. During the Calvin cycle, an enzyme called RuBisCO facilitates the reaction between carbon dioxide and a compound called ribulose bisphosphate (RuBP). This reaction in combination with the energy and reducing power of ATP and NADPH results in the creation of Glyceraldehyde-3-phosphate (GA3P) molecules, thereby storing the energy from photosynthesis for the plant's use.
The Calvin cycle can be divided into three stages: fixation, reduction, and regeneration. With ATP and NADPH produced through light-dependent reactions of photosynthesis, CO2 is transformed into carbohydrates in a process that involves regeneration of RuBP. In summary, the Calvin cycle provides a method for plants to convert sunlight energy into chemical energy, which is stored in carbohydrate molecules and used for plant growth.

Many biologists argue that the euglenoids should be classified as an animal-like protist rather than a plantlike protist
Euglenoids are a group of unicellular organisms with both animal-like and plant-like traits, leading to classification challenges. Taxonomy and phylogeny based on molecular genetics and genome analysis have led to a restructuring of the kingdom Protista into multiple monophyletic supergroups, taking into account convergent evolution.
The question addresses the classification of euglenoids, which are unicellular organisms with both animal-like and plant-like characteristics. This classification ambiguity arises because euglenoids exhibit mobility and some are heterotrophic, which are traits associated with animals, leading zoologists to sometimes refer to them as 'Euglenozoa'. On the other hand, some euglenoids are capable of photosynthesis, a plant-like trait, causing botanists to call them 'Euglenophyta'. The taxonomy and phylogeny of euglenoids, and protists in general, have been reshaped with the advent of molecular genetics and genome analysis. These analyses have revealed deep evolutionary branches within the domain Eukaryota, dividing it into several monophyletic supergroups. The classification continues to evolve as new genetic information is discovered, making clear that morphologically similar protists may not necessarily share a recent common ancestor—a concept known as convergent evolution.
Due to increasing concentrations of ddt as one moves up the food chain, cormorants and mergansers have about ______ times as much ddt residue as the background concentration in the water.
Biomagnification leads to a 400-fold increase in the concentration of DDT in birds like cormorants and mergansers compared to the background concentration in the water.
The question addresses the phenomenon of biomagnification, which refers to the increasing concentration of a substance, such as DDT, in the tissues of organisms at successive levels in a food chain. This process occurs because DDT is not metabolized or excreted efficiently by organisms, and therefore accumulates in their bodies, particularly in fat tissue. As smaller organisms that contain DDT are eaten by larger ones, the concentration increases.
Hence, apex predators and birds like cormorants and mergansers, which are higher up on the food chain, can have concentrations of DDT that are significantly higher than the background concentration in the water. In the case of birds feeding on fish that have accumulated DDT, it has been documented that they can have a 400-fold increase in the concentration of DDT.

A wedge-capped capuchin is a species of South American monkeys. They live in groups that typically have one male and several females. Sometimes young males live in a group too in order to help take care of the young. Most groups have a dominant female that often displays aggression toward other females and young males in the group. Which best describes the group behavior of these monkeys? territorial imperative social hierarchy migratory hibernating
Answer:
The correct answer would be the social hierarchy.
Explanation:
A basic aspect of social organization that is decided by display behavior or fighting and leads to a ranking system or order of place of the animals in a group is known as social hierarchy.
Dominance type of social hierarchies often decided best or early access to mating, social interactions, or food within animal groups.
Wedge-capped capuchin monkeys show this type of social hierarchy in their pack or group where dominant females display aggression towards other young males and females.
Thus, the correct answer is the social hierarchy.
In low-nitrogen conditions UCYN-A participates ina mutualistic symbiotic relationship with other organisms in the microbial mat. predict the most likley typre of symbiotic relationship between UCYN-A and the other organisms in the microbial mat if nitrogen becomes readily available from another source. provide reasoning to support your prediction

Which term best describes traits that are found on the x chromosome but not on the y chromosome?
Final answer:
X-linked traits are determined by genes on the X chromosome and are not present on the Y chromosome, leading to different inheritance patterns in males and females.
Explanation:
The term that best describes traits that are found on the X chromosome but not on the Y chromosome is X-linked traits. These traits are controlled by genes that are located only on the X chromosome. In human females, who have two X chromosomes (XX), these traits have a higher likelihood of being expressed. In contrast, human males, who have only one X chromosome paired with a Y chromosome (XY), can express these traits if the gene is present on their single X chromosome, leading to distinctive patterns of inheritance for X-linked traits.
X-linked traits can have significant implications for the expression of certain conditions, such as color blindness and hemophilia, which are more commonly observed in males due to the presence of only one X chromosome. The absence of a corresponding gene on the Y chromosome means that if a male inherits an X-linked recessive trait, he will express that trait since there's no dominant allele on the Y chromosome to mask the effect of the recessive allele on the X chromosome.

What is the advantage of having muscles that run at different angles in the stomach?
The stomach has three layers of smooth muscle fibers run in three different angles. These layers are critical in giving the stomach the capability to mix, well, ingested food as it is mixed with enzymes and hydrochloric acid. This is important because smoothe muscles can only contract in one direction hence the layers give multidirectional movements of the stomach hence goof mixing and better digestion.
