Answer:
The correct option is A. His research was not appreciated by the scientific community until after he died.
Explanation:
Gregor Mendel was an Austrian monk who laid the foundation of genetics. Mendel studies seven traits from the pea plants and formed the law of segregation and law of independent assortment.
The work of Mendel was not appreciated until his death. In the 20th century, his work was eventually rediscovered and appreciated.
However, Mendel's study did not include any explanations for polygenic traits. His results could predict heritability in both plants and animals.
Answer:
Compounds from different organisms are being used widely bu humans for their benefits. Some of the compounds are used as drugs. For example, penicillin is used as a drug or antibiotic. There are many plants which provides humans with other types of medicines and herbal remedies. There are other compounds which are used for cancer treatment. For example, taxol is a compound obtained from trees which are being used as anticancer drugs.
Answer: For flowering plants, fertilization occurs through a process known as double fertilization. Unlike most plants, double fertilization enables the new seed to grow into a new plant and have a food source to begin growing. Double fertilization occurs within the female part of a plant, the pistol.
explanation: When pollen is formed by the anther, or male part of a plant, it will blow in the wind or attach to an organism that carries it to the top of the pistol, known as the stigma. Once the pollen attaches to the stigma, the pollen germinates and forms a pollen tube that extends into the ovary. Once formed, two sperm cells will be released and fertilize both the egg and the two polar nuclei of the plant to form the zygote and endosperm, respectfully.
Muscle contraction that results in a change in joint angle is called <span>concentric contraction.
This contraction occurs when enough force that can overcome the resistance applied is developed by the muscle where this force developed is larger than the force of the resistance applied.</span>
Answer:
For example, cheetahs and lions both feed on the same prey; they compete for this resource. Therefore, if they live in the same area, one or both species will have less food. You might expect them to fight each other over food, but they do not
