Answer:
having a family history of a certain disease
Explanation:
The orca's body, like that of other living creatures, is made up of cells. Eukaryotic cells are seen in orca whales. Cells of this sort can be found in all mammals. A nucleus is found in eukaryotic cells. The nucleus is the cell's brain. The nucleus directs the activity of the cell in the same way as the human brain directs the movements of the body. DNA is found in the nucleus. The blueprint for an animal's body is DNA. The genetic code is carried by DNA. The messenger RNA transports the DNA information to the ribosome, which is where proteins are produced. Organelles, which serve as miniature organs with various functions, are found in every cell. Killer whales have 44 chromosomes, and an outstanding banding investigation on six killer whales revealed significant C-band variation. Because they have complex cells, killer whales are classified as Eukaryotes. Membrane-bound organelles, including a nucleus, are found in their cells.
<u>Answer</u>:
Squatting to a pet dog before a run will activity create tension in the legs.
<u>Explanation</u>:
Tension in muscle contraction generates tension in the muscle fibers. In natural movements of locomotion the muscle contractions produce changes in length and tension in the muscle fibers of skeletal muscle. The sliding of protein filaments past to each other inside skeletal muscle fiber produces a contraction.
When the muscles is stretched or shortened beyond its normal level a tension which resist the change in the muscle length is felt. Among the above mentioned options the maximum tension can be observed in the following order: squatting to pet a dog > stretching your legs before a run > pressing a car's accelerator pedal > standing for five minutes (no active tension).
The pancreas secretes trypsin and chymotrypsin enzymes which continue breakdown proteins into smaller peptides and some single amino acids. Carboxypeptidase also secreted by the pancreas splits single amino acids from the carboxyl end of proteins.
Bile, which contains a mix salts, is secreted by the liver . Bile salts help to continue digestion of fats by attaching to small fat droplets, preventing them from coalescing into larger droplets, thereby increasing their surface area so that they can be further broken down by lipase enzymes.
