Meiosis increases genetic variation due to random segregation which occurs.
In anaphase I of meiosis, the homologous pairs (one maternal and one paternal chromosome) are moved apart to opposite ends of the cell and this process occurs random. This allows the formation of gametes with different sets of homologues. In this phase sister chromatids remain attached at their centromeres (not segragated as in mitosis).
The answer is Object 3.
Atoms in a solid are locked and can only vibrate in one place. So, it can’t slide past each other or spread out to fill the containers (objects 1 & 4 are out). Viscous means having a thick and sticky consistency between solid and liquid, so I’m guessing it’s something like glue or syrup, which is not a solid. That leaves Object 3 left.
Answer:
The correct answer is a. Stretch receptors in the wall of the urinary bladder signal the sacral region of the spinal cord.
Explanation:
The answers that take place automatically and quickly are called reflexes. When the smooth muscle in the bladder wall is stretched, the micturition reflex is triggered. Micturition (Urination) is the act of emptying the bladder (urinating). When the bladder is full of urine, the bladder wall stretch receptors trigger the micturition reflex. The detrusor muscle surrounding the bladder contracts. The internal urethral sphincter relaxes and allows urine to leave the bladder and pass into the urethra. Those two reactions are involuntary. The external urethral sphincter is voluntary. You must relax so that the urine passes through the urethra and leaves the body.
