Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
Answer: Epidermal dendritic cells help prevent infections and they also produce pigment for the skin.

Lister’s work was only made possible by Louis Pasteur’s discoveries.
- Louis Pasteur developed the pasteurization technique, which involves heating liquids and then letting them cool in order to kill bacteria, after learning that microbes were the cause of alcohol that had soured.
- His research on germ theory also inspired him and his team to develop the anthrax and rabies vaccines.
- Only Pasteur's discoveries made Lister's research possible. Infection was first thought to be caused by germs according to Pasteur.
- Lister developed the concepts of sterile surgery based on the "germ theory."
- Surgery was transformed into a sterile procedure thanks to Lister and Pasteur.

Answer:
2. tRNAQ binds the A site of the ribosome.
1. The polypeptide is transferred to tRNAQ.
4. The ribosome shifts, with tRNAQ still bound.
3. tRNAQ binds the P site of the ribosome.
4. The ribosome shifts, with tRNAQ still bound.
5. tRNAQ binds the E site of the ribosome.
Explanation:
tRNAQ first lands on the A site of the ribosome. It carries an amino acid according to the exposed codon on A site. A bond is formed between the amino acid of A and P site such that the polypeptide is transferred to tRNAQ. The ribosome shifts now and tRNA Q moves to P site from A site while still bound to mRNA. Another tRNA enters the A site and the above process is repeated which finally transfers the polypeptide chain from tRNAQ to new tRNA. tRNAQ has no attached polypeptide now and is ready to leave the translation complex. The ribosome shifts again with the tRNAQ still bound to mRNA. tRNAQ enters the E site from P site and finally leaves the translation complex by exiting the E site.
Answer:
Biodiversity is essential for the processes that support all life on Earth, including humans.
Explanation:
Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants, and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat. And people also value nature of itself.
