Mendel cross-pollinated flowers by removing anthers from one plant and transferring the pollen to the stigma of another plant. This technique allowed him to control which plants were bred together for his experiments.
Mendel cross-pollinated flowers using a technique known as controlled pollination. He removed the male reproductive structures (anthers) from one plant and transferred the pollen to the female reproductive structures (stigma) of another plant of the same species. This allowed Mendel to control which plants were bred with each other, helping him study the patterns of inheritance.

Mendel cross-pollinated flowers by manually transferring pollen from the anther of one plant to the stigma of another, removing the anthers from the recipient plant to prevent self-fertilization. For example, he crossed a plant with violet flowers with one with white flowers, finding that all the offspring had violet flowers.
Gregor Mendel, the father of modern genetics, used a process of cross-pollination in his experiments with pea plants. The method of cross-pollination involved manually transferring pollen from the anther (the male reproductive organ) of a mature pea plant of one variety to the stigma (the female reproductive organ) of a separate mature pea plant of the second variety. To prevent self-fertilization and ensure pure cross-pollination, Mendel painstakingly removed all of the anthers from the plant's flowers that were set to receive pollen, before the anthers had a chance to mature.
For example, Mendel applied the pollen from a plant with violet flowers to the stigma of a plant with white flowers. He then gathered and sowed the seeds that resulted from this cross. Contrary to popular belief at the time, which posited that traits from parent plants would blend in the offspring, Mendel's results revealed that traits are instead inherited discretely. In this case, 100% of the first-generation hybrid plants had violet flowers, demonstrating that the white flower trait had completely disappeared.

Answer;
Carbohydrates;
The macromolecule that provides a person with most of the energy that is needed for daily activities is carbohydrates.
Explanation;
-Biological macromolecules fall into four categories: carbohydrates, proteins, lipids and nucleic acids. The body uses carbohydrates, lipids and proteins for energy.
Carbohydrates are the main source of energy and for structural purposes, Lipids are used to store energy; important parts of biological membranes and waterproof coverings, Nucleic acids helps to store and transmit hereditary or genetic information. Proteins functions as a source of energy and to control the rate of reactions and regulate cellular process.

Answer;
D. The Open Marine ecosystem
Explanation;
An ecosystemis the lowest level of environmental complexity that includes living (biotic factors)and nonliving factors (abiotic factors).
-The Open marine ecosystem contains the fewest photosynthetic producers, this is because most producers can't live or survive in an areas with the lack of nutrients or sun light. They need nutrients for growth and also sunlight to undertake the process of photosynthesis which helps them make their own food.
The D. open ocean is the marine ecosystem that contains the fewest producers, such as phytoplankton.
Marine ecosystems are diverse and complex aquatic environments found in oceans, seas, and coastal regions. They support a wide range of life forms, from microorganisms to large marine mammals. These ecosystems play critical roles in Earth's climate regulation, nutrient cycling, and food production, making them vital for global ecological balance.
The marine ecosystem that contains the fewest producers is the open ocean. The open ocean is characterized by low levels of nutrients and sunlight, which limits the growth of producers such as phytoplankton. Instead, the primary producers in the open ocean are photosynthetic bacteria and archaea, which can thrive in these extreme conditions.
