Answer:
In the first step, the information in DNA is
transferred to a messenger RNA (mRNA)
molecule by way of a process called
transcription.... The mRNA sequence is
thus used as a template to assemble-in
order-the chain of amino acids that form a
protein.
Similarities: Mitosis and meiosis both involve cell replication. They both involve prophase, metaphase, anaphase, and telophase.
Differences: Meiosis creates gametes while mitosis creates somatic cells. Mitosis creates two daughter cells, while meiosis creates four sperm cells in men and one egg cell and three polar bodies in women. Mitosis involves one round of cell division, while meiosis involves two. Mitosis creates cells that have the same number of chromosomes as the original cell, while meiosis creates cells that have half the number of chromosomes as the original cell.
Hope that helped you.
P.S. There are more similarities and differences, challenge yourself and see if you can find them! Good luck.
Answer:
d.The wing-assisted incline running theory postulates that wings were initially used to maintain balance while climbing up slopes.
Explanation:
Two theories were given to explain the origin of avian flight. The top-down theory suggested that the birds' ancestors were tree dwelling species. They took help of wings to glide from tree to tree in order to avoid predator or catch prey. The bottom up theory suggested that the birds' ancestors were ground dwelling species. They took help of wings to maintain a balance and provide a lift for efficient running.
Wing-assisted incline running was a mixture of both the above theories and gave a balanced view point. According to it, birds' ancestors used wings to maintain a balance while running up inclined slopes. The wings helped them to save energy while scaling slopes and eventually a flight mechanism was also developed.
Sorry, it was easier to do it like it’s, hope you can read it! And hope it helps
