Answer:
Gregor Mendel belonged to a family of farmers but he went to pursue academic studies. all these things combined with his curiosity resulted in his research studies.
Explanation:
An Austrian monk by profession, Gregor Mendel through experimental studies in his garden, discovered the basic principles of heredity. Mendel 's observations have become the basis of modern genetics and the study of heredity, and he is universally recognized as a foundation for the development of genetics. His strong will led him away from his family occupation of farming. More working in a church it was no less than a revolutionary step to choose science above faith, especially at that time.
<span>The answer is d. Meiosis produces haploid cells, while mitosis produces diploid cells.
Meiosis begins with diploid cells but further divides into four daughter cells. Mitosis produces 2 diploid cells</span>
Adaptations,inherited traits that increase an organisms chance of survival, also determine an organism’s niche.
<u>Explanation:</u>
An adaptation is a variation, or genetic modification, that supports an organism, such as a plant or animal, to endure in its environment. An adaptation can be architectural, suggesting it is a physical portion of the organism. An adaptation can also be behavioral, influencing the way an organism responds. An adaptation is a feature of an organism that raises its possibilities of surviving and/or reproducing.
Organisms are frequently well modified to the abiotic and biotic requirements of the circumstances in which they live. An organism’s adaptations are a consequence of the genes the organism derives from its parents.
Answer:
Nonspecific resistance; adaptive immunity
Explanation:
The immune response against any antigen can be specific or non- specific. The specific immune response is provided by lymphocytes like B lymphocyte and T lymphocytes because after interaction with antigen they differentiate into memory cells which is saved in memory and when that antigen comes again in the body the memory cell easily ward it off. This type of immunity is called adaptive immunity.
In non-specific immunity, memory is not made after interaction and killing of the antigen or microbes by immune cells because the antigen is killed non specifically. Non-specific resistance is provided by phagocytic cells mainly.
Answer:
The responding (dependent) variable
Explanation:
In an experiment, one of the variables is either changed/maipulated or measured. The variable that is deliberately changed is called the INDEPENDENT VARIABLE while the variable that responds to the changes made to the independent variable, or is being measured is called DEPENDENT VARIABLE.
Hence, in the experiment involving the height of the ramp and the speed of the skateboard, the SPEED OF THE SKATEBOARD IS THE DEPENDENT/RESPONDING VARIABLE because it is the variable being measured.
