The answer is cross-pollination, by using parents that had different traits.

Gregor Mendel researched pea plants and he <span>established the principles of heredity. To explain his experiments and discoveries, he invented terms dominant and recessive in reference to traits. In his experiments, he used cross pollination which includes the crossing of parents with different traits. For example, he crossed a plant with green peas and a plant with yellow peas (two different traits) and studied how  these traits are inherited to the next generation.</span>

Answer:

Placing salty water in  A and distilled water in  B.

Explanation:

The fastest net rate of water movement into the A-side will occur if we place salty water on that side and distilled water in the other one. The reason for this is that the A-side contains a higher concentration of solute than B. So, the water will pass the semipermeable membrane and go to the A-side to valance the concentrations on both sides. As we can see, there is an increase in the net rate of water movement into A.

The mechanism that breaks the linkage between linked genes is
gregori [183]

Answer:

Crossing over

Explanation:

Crossing over is the process during which two chromatids of two homologous chromosomes exchange part of their genetic segments. It occurs during the pachytene stage of prophase I of meiosis I.

Linked genes are mostly inherited together and do not exhibit independent assortment. However, when linked genes are present far apart from each other on the same chromosome, crossing over can occur between them to produce recombinant chromatids. Therefore, crossing over can break the linkage and produce recombinant progeny as it occurs during the independent assortment of unlinked genes.

Since there is one molecule of glucose used per 6 molecules of carbon dioxide released, if you have 100 molecules of glucose, then you multiply the carbon dioxide by 100 which is 600. Thats what I would say but I might be wrong.

Answer:

Use of recycled products and renewable energy.

Explanation:

Use of recycled products and use of renewable energy are the solutions which provide resources to everyone and no damage cause to the ecological systems of the environment. By using recycled products have two advantages i. e. the product's price decreases and no pollution occurs while the use of renewable energy such as use of solar radiation for the production of electricity. With this energy, no pollution occurs in the environment and electricity can be provided to a lot of people with low cost.
