The nucleus is the part of the cell, or organelle, that contains the genetic material and controls the cell's movement. It consists of the genetic material, the nucleoleus, and the nuclear membrane.
Nucleus- the nucleus controls all of the cells activities, including how the cell grows,develops,and divides.
Answer:
C) lumbar vertebrae; short, flat spinous processes
Explanation:
The Lumbar Vertebrae are bigger and stronger than vertebral bodies in certain positions.
The vertebral bodies and disks bares majority of the body weight of the body. The lamina, facets and spinous process are basic components of the posterior materials that assist in guiding the movement of the vertebrae and as a coverage or protective shelter for the spinal cord.
The spinous process are SHORT and STURDY (FLAT) in the Lumbar Vertebrae. Hence, this explain why it is often referred to as "Hatchet-Shaped".
The attached image as red dots meant to point to the spinous process in the Lumbar Vertebrae.
The pipettes can basically be characterized into five grades. these grades includes the serological, disposable, repeat, single channel and multi-channel pipette. The guidelines for the usage of each of these pipettes differ. However, some instructions are common, such as the control of the flow of liquid. The index finger is used for the purpose of controlling the flow of the liquid from the pipette.
Hence, the answer is 'index finger'.
B) increases the genetic variability of the offspring because there are more genes presemt
