Answer:
El árbol de la vida o árbol universal de la vida es una metáfora, modelo y herramienta de investigación que se utiliza para explorar la evolución de la vida y describir las relaciones entre organismos, tanto vivos como extintos, como se describe en un famoso pasaje de El origen de las especies (1859) de Charles Darwin.2
Explanation:
Answer:
The correct answer would be A. somatic nervous system.
A somatic nervous system is sub-set of the peripheral nervous system which controls the voluntary actions and body movements with the help of skeletal muscles.
This system mainly consists of two types of nerves:
Afferent nerves: Theses are sensory nerves which carry stimulus or information from receptors to the central nervous system (brain and spinal cord).
Efferent nerves: These are also termed as motor nerves which carry commands or responsive information from the central nervous system to the muscles.
The muscles contract and produce movements.
Answer:
All of the above.
Explanation:
Garden peas were used by Mendel for experiment and are good choice of studying heredity because they have the ability to control their fertilization and transfer pollen . They can engage in either self fertilization or cross's fertilization.
Garden peas are easy to grow and they can be bred very easily and they have alot of traits that can easily be observed i.e their characteristics are visible and they produce many offsprings.
They are of different varieties.
Adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
Answer with Explanation:
Two genetic concepts were discovered before 1900.
a. preservation of beneficial traits (This was discovered by Charles Darwin in 1859. This theory provided the details about how an organisms survives and adapted to new environment.)
c. calculation of Mendelian inheritance (This was discovered by George Mendel in 1865. This law provided the detail about how genetics is inherited to offspring and what happens when traits move from one generation to other generation.)
