Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments. ... The offspring that result from such a cross are called hybrids.

Answer:

Abiotic factors, such as temperature, water, sunlight amounts, and regional terrain, directly effect biotic factors. Biotic factors are the living components of an ecosystem which include primary producers, consumers, and dexomposers.

Abiotic factors can effect organisms in many ways. Hey can effect primary producers negatively if there is too little sun, water, or nutrients in the soil. However, if there is too much of any one of these, they can still be negatively effected. With primary producers, it’s all about balance.

while consumers do not directly require the above conditions, they do rely on the plants and animals that feed on said plants to survive. If the plants do not have correct nutrients, they will not either. As far as terrain goes, they adapt to better cope with the environment. If they live in an aquatic enviromment for example, they acquire ways to more efficiently move through the water to look for food.

Decomposers rely on the remains of dead plants and animals in order to survive. They feed off of dead matter and the waste gets deposited into the soil. This in turn helps to give the soil its nutrients, and so the cycle continues.

Everything in nature is reliant on each other. This delicate balancing act is both beautiful and so very fragile. If one organism is removed, the entire ecosystem could suffer. This is why it is so critical to protect the environment we share with every other living creature on this earth.

What is an example of a chromosomal nondisjunction that occurs during the first division?
aliya0001 [1]
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division. There are three forms of nondisjunction: failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis.[1][2][3] Nondisjunction results in daughter cells with abnormal chromosome numbers (aneuploidy).

Calvin Bridges and Thomas Hunt Morgan are credited with discovering nondisjunction in Drosophila melanogaster sex chromosomes in the spring of 1910, while working in the Zoological Laboratory of Columbia University.[4]

Movement of the particles across the membrane stops when the concentration gradient no longer exists, the particles will continu
Leviafan [203]

Answer:

Once the concentration gradient no longer exists, particles will continue to diffuse due to random motion.

Explanation:

When there is a permeable membrane between two solutions with different concentrations, the concentration gradient will go from the compartment with more particles to the one with fewer particles to valance the concentrations on both sides of the membrane. Once the concentrations are equal, particles will still randomly move from one side to the other, but the number of particles that move to one side is almost the same as the number of particles that move to the other, so there is still valance and the same concentration in both sides.
