Chemical digestion involves breaking down the nutrients into smaller cells
Physical digestion is using physical movements such as chewing and swallowing
Answer: B. Tendon
Explanation:
A tendon is a fibrous connective tissue which attaches muscle to bone. A tendon serves to move the bone or structure. Tendons may also attach muscles to structures such as the eyeball. While a ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
A bursa is a tiny fluid-filled sac that functions as a gliding surface to reduce friction between tissues of the body. The plural of bursa is bursae. There are 160 bursae in the body. The major bursae are located adjacent to the tendons near the large joints, such as the shoulders, elbows, hips, and knees.
A fascia is a band or sheet of connective tissue, primarily collagen, beneath the skin that attaches, stabilizes, encloses, and separates muscles and other internal organs. From the various definitions given above shows that the tendon is the correct answer to the question asked.
My guess:
I do not know the options to the blanks, but I'd say that the answer to the first one is "strongly linked". Think of a chromosome as a phylogenic chart → 2 species that are beside each other are strongly linked, if compared to 2 species 3 spots apart form each other. So, 2 genes that are close to each other are strongly linked.
I do not know the options to the blanks, but I'd say the answer to the second one is epistasis → which is the interaction between two different genes (different means they're not linked alleles).
Hope it helped,
