Answer:
e. bind to troponin which moves the tropomyosin.
Explanation:
Troponin (Tn) is a protein complex composed of three different proteins: troponin C (TnC), troponin I (TnI), and troponin T (TnT). This complex is found both in skeletal muscles and cardiac muscles, where TnC attaches calcium ions through four and three calcium ion-binding sites, respectively. When a muscle is relaxed, Tn attaches to tropomyosin to prevent muscle contraction. During muscle contraction, calcium channels open and cytosolic calcium ions bind to TnC, thereby Tn changes its conformation and moves the tropomyosin. This process relieves the inhibition of the interaction between actin and myosin filaments, which makes muscle contraction possible.
True because, more variation increases the species fitness, the ability to survive and reproduce. Allowing the organism to pass on their beneficial traits (advantageous traits), to their offspring.
In dog waste, there is a chemical called fecal coliform bacteria. this bacteria is harmful to plants and animals alike, if this compost was used on plants, eating the plants would be bad news. the bacteria can cause cramps, diarrhea, intestinal illnesses, and even serious kidney issues in people. dog poop mostly carries these things
Whipworms
Hookworms
Roundworms
Tapeworms
Parvo
Corona
Giardiasis
Salmonellosis
Cryptosporidiosis
Campylobacteriosis
pet droppings contribute to diseases spread from animals to people called zoonoses, using the pet poop in the compost can make the bacteria linger for years, making further crops infected too.
(really hope this helps!)
Answer:
photosynthesis is the way b plants get their energy
Explanation:
I would help but this is the type of project to do on your own. I'd suggest planning out the image then building from there, or use graphs on the internet for inspiration. I wish you luck though :>
