Explanation: Isometric or Cubic system is the simplest of all the crystallographic system. It is comprised of three crystallographic axes of same length which are all perpendicular to one another. The shape of its unit cell is cube shaped. For example, diamond, garnet and gold.
It contains three kinds of symmetry axes, such as-
there are two types of endoplasmic reticulum, rough endoplasmic reticulum and smooth endoplasmic reticulum, the rough endoplasmic reticulum is the site of protein manufacture( because it has ribosomes) whereas the smooth endoplasmic reticulum manufactures fat molecules or lipids. these lipids helps in membrane biogenesis, which is the process of formation of plasma membrane. the main function of the endoplasmic reticulum is that it serves as channel for transportation of proteins etc between various cells or a cell organelle and another cell. In the liver, detoxification of poisons take place due to the help of smooth endoplasmic reticulum.
C. Lizards were the first organisms on Earth to have limbs.
Explanation:
This cladogram illustrates when and in what species novel anatomical traits occurred. All the organisms that follow after a certain point will have this trait present. Thus, earthworms are the first species to evolve segmented bodies which will be present in all the following organisms such as salmons. Here, segmentation is found in the vertebrae of the backbone as well as in the muscles and nerves that spread from the spinal cord, at a finer level.
This cladogram does not illustrate the evolutionary time relationship between different species. Thus, it cannot be inferred that the kangaroos evolved after earthworms.
Based on your religion, you may be told that any nonbelievers will go to a bad place; Hell, the Underworld, left to roam the world of the living never to pass on to the next life, etc. As an Evolutionist or Atheist, I don't know what happens to me when I die. I belive my body will remain on this earth (unless I get my body shipped off world into space for disposal lol), while my mind and conciousness fades away.
