Answer
The arm and base of microscope are connected with each other with help of inclination joint. which provide easiness to user during research analysis or other microscopic studies.
It has significant role in light and compound microscope that need light for visualization of examine sample. It also help in easy rotation during focusing toward light for better contrast.
Lysosomes break down and recycle worn out cells.
Explanation:
During sexual reproduction, two sex cells fuse to create a fertilized cell with a complete set of chromosomes. ... Result is 2 identical cells with 46 chromosomes.
A mutation within a gene that will insert a untimely cease codon in mRNA would result in a shortened polypeptide chain.
<h3>What occurs if there is a untimely end codon?</h3>
Thus, nonsense mutations occur when a premature nonsense or end codon is added in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins
<h3>What mutation motives untimely cease codon?</h3>
In genetics, a nonsense mutation is a factor mutation in a sequence of DNA that effects in a premature stop codon, or a nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and normally nonfunctional protein product.

Answer:
Relaxation of the dartos muscle.
Explanation:
Testes are present in scrotum outside the pelvic cavity to maintain the temperature about 2-3 degrees Celsius below the body temperature as required for sperm production. Dartos muscle is the layer of smooth muscle located in the superficial fascia. The contraction of dartos muscle serves to make the skin of the scrotum wrinkled and tight.
During hot weather, the dartos muscle relaxes and makes the surface of scrotum less wrinkled to increase the loss of the heat from its surface. The increased heat loss from the surface of scrotum due to relaxed dartos muscles keeps the testes protected from heat.
