Review Quiz On Photosynthesis Cycle! Trivia Facts

Ribosomes are the correct answer for this question. Ribosomes are the cellular structures responsible for protein synthesis. They are found in all living cells and can be found either floating freely in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes read the genetic information stored in the DNA and use it to assemble amino acids into proteins. Therefore, ribosomes play a crucial role in the production of proteins within the cell.

DNA is found in the cell's nucleus. It is a molecule that carries genetic instructions for the development, functioning, and reproduction of all living organisms. The cell's nucleus is the control center of the cell and houses the DNA. Therefore, the correct answer is DNA / the cell's nucleus.

Sunlight and water are limiting factors in an environment because they are essential for the survival of organisms. Sunlight is necessary for photosynthesis, the process by which plants produce food, and it also provides warmth and energy. Water is crucial for hydration, nutrient absorption, and maintaining physiological functions. Without sufficient sunlight and water, organisms would not be able to meet their basic needs and would struggle to survive in their environment.

Greenhouse gases are gases that trap heat in the Earth's atmosphere, leading to the greenhouse effect and global warming. Excess CO2 is one of the main greenhouse gases responsible for climate change. Therefore, the correct answer is "greenhouse gases."

The flower is a reproductive system because its main function is to produce and facilitate the reproduction of plants. Flowers contain reproductive organs such as the stamen (male reproductive organ) and pistil (female reproductive organ), which are responsible for the production of pollen and ovules respectively. These organs allow for the process of pollination and fertilization, leading to the formation of seeds and the continuation of plant species.

Pioneer species play a crucial role in ecological succession by breaking down rock and forming soil, which provides a foundation for the growth of other plants. They are the first organisms to colonize barren or disturbed areas and are able to thrive in harsh conditions. Through their ability to break down rocks and organic matter, pioneer species contribute to the process of soil formation, making it more suitable for other plant species to establish and grow. This process sets the stage for the development of a diverse and stable community over time.

Cross-pollination creates a unique offspring because it involves the transfer of pollen from the male reproductive organ of one plant to the female reproductive organ of another plant. This process allows for the mixing of genetic material from different plants, resulting in offspring that have a combination of traits from both parent plants. Self-pollination and after-pollination, on the other hand, involve the transfer of pollen within the same plant or from the same plant, respectively, which does not result in as much genetic diversity.

Succession refers to the process of ecological change over time in a particular area. It typically begins with pioneer species, which are the first organisms to colonize a barren or disturbed area. These species are often hardy and able to tolerate harsh conditions. As the environment becomes more stable, bushes and dwarf trees start to grow, followed by the establishment of mature trees. This sequence of pioneer species, bushes, dwarf trees, and mature trees represents the stages of succession, with each stage paving the way for the next.

In an experiment, the control refers to the variable or condition that is kept constant or unchanged throughout the experiment. It serves as a baseline or reference point against which the effects of other variables are measured. By keeping the control constant, the experimenter can accurately determine the impact of the variable being tested.

Photosynthesis is the correct answer because it is the process by which plants and other organisms convert carbon dioxide into oxygen, helping to maintain balance in the carbon cycle. During photosynthesis, plants take in carbon dioxide from the atmosphere and release oxygen, which is then used by other organisms. This continuous cycle of carbon dioxide uptake and oxygen release helps to regulate the levels of carbon dioxide in the atmosphere, preventing it from accumulating and causing imbalances in the carbon cycle.

The independent variable in an experiment is the factor that is deliberately manipulated or changed by the researcher. It is the variable that is believed to have an effect on the dependent variable. In other words, it is what is being tested or investigated in the experiment. The independent variable is important because it allows researchers to determine cause-and-effect relationships and draw conclusions about the impact of the manipulated factor on the outcome of the experiment.

The white dots will move to the right because they are moving from a high to low concentration.

The correct answer is 50% because if the question is asking about the percentage of recessive traits, then it implies that the other percentage would be for dominant traits. In genetics, traits are inherited through genes, and each gene has two alleles, one dominant and one recessive. If an individual inherits one dominant allele and one recessive allele, the dominant trait will be expressed. Therefore, if the recessive trait is 50%, it means that the dominant trait would also be 50%.

The correct answer is "impermeable." This means that the membrane does not allow substances to pass through it. In the context of the question, it suggests that the membrane does not allow anything to pass through to the red blood cells.

Adhesion refers to the attraction between water molecules and other surfaces. It occurs when water molecules are attracted to the molecules of a different substance, causing them to stick together. This phenomenon is responsible for water sticking to the sides of a glass or the surface of a leaf. Cohesion, on the other hand, refers to the attraction between water molecules themselves, causing them to stick together and form droplets. Subhesion is not a recognized scientific term.

The dependent variable of an experiment is what is being measured or observed. It is the outcome or result that is expected to change as a result of the independent variable, which is the factor being manipulated or changed by the experimenter. The dependent variable is the variable that is dependent on the independent variable and is used to assess the effect or impact of the independent variable on the experiment.

The correct answer is oval, because animal cells do not have a cell wall and typically have smaller vacuoles compared to plant cells.

A static system refers to a system that remains unchanged or at rest over time. Measurement can be considered as an example of a static system because once a measurement is taken, it remains constant and does not change unless it is measured again. In contrast, body systems, cars, and ecosystems are dynamic systems that undergo continuous changes and interactions. Therefore, measurement is the best example of a static system among the given options.

The letters A and C are only found in a plant cell.
