Between 1884 (the year Mendel died) and 1888 details of mitosis and meiosis were reported, the cell nucleus was identified as the location of the genetic material, and "qualities" were even proposed to be transmitted on chromosomes to daughter cells at mitosis. In 1903 Walter Sutton and Theodore Boveri formally proposed that chromosomes contain the genes. The Chromosome Theory of Inheritance is one of the foundations of genetics and explains the physical reality of Mendel's principles of inheritance.
That process is known as Respiration in which oxygen get exchanged from the carbon dioxide by alveoli...
Answer:
A. ponds are shallower than lakes
E. lakes are colder and darker at the bottom than ponds
Answer:
Diffusion helps animals in respiration. The cells in an animal's body need glucose and oxygen for respiration. Both these are carried in the blood. When blood reaches the cells the molecules of glucose and oxygen diffuse out of the blood and into the cells. As cells use up the glucose and oxygen they produce waste chemicals and carbon dioxide.
Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells. This helps the plants to photosynthesize and produce more food.
Example for animals: Animals using glucose and oxygen in diffusion.
Examples for plants: Plants using carbon dioxide to photosynthesize.
25 x 8
8 x 5 = 40 you put the 4 on top of the 8 and put the zero as your first number on your answer
8 x 2 = 16
then you get the 4 on top of the 8 and then add 16
16 + 8 = 20
20 -- 0
200
plz mark me as brainliest :)
