The process is called homeostasis.
Answer:A. The release of calcium ions causes myosin and actin to attach to each other.
The contraction of skeletal muscles takes place by induction of a nerve impulse, which produces a movement and the interaction of the filaments containing proteins named as actin and myosin. This interaction of filaments is regulated by proteins called tropomyosin and troponin present on the actin filaments. The motor nerve causes the depolarization of the muscle membrane sarcolemma. This triggers the sarcoplasmic reticulum to release calcium ions. This calcium binds to troponin and thus allows the tropomyosine strand on the actin filament to displace so that the part of the actin where myosine head needs to be attached remain uncovered. Binding of the actin myosine filament results in contraction.
Hence, the release of calcium ions causes myosin and actin to attach to each other causes muscle contraction.
Okay My three Consumers I’m going to use are-
•Herbivores
•Carnivores
•Decomposers
Explanation~
For herbivores there living things that eat only plants to get energy so an example of that could be Whales,Elephants, Cows etc
Carnivores are meat eaters soo those would be animals like owls,Tigers,Sharks etc
Decomposers break down dead plant and animal material and examples of those would be Earthworms and Mushrooms
HOPE THIS HELPED!!
Answer:
mutualism
Explanation:
It's a symbiotic relationship beneficial to both symbionts.
in this case E. Coli helps with the absorption of Vitamin K and other important vitamins for the human body in the colon. While, Human (host) provides shelter for it
Answer:
Do Nitrogen, Phosphorus, and Potassium Fertilizers Do for Plants? Nitrogen in Fertilizer. In simple terms, nitrogen promotes plant growth. It is associated with leafy, vegetative growth. Phosphorus in Fertilizer. Phosphorus is involved in the metabolic processes responsible for transferring Each of these fundamental nutrients plays a key role in plant nutrition. Nitrogen is considered to be the most important nutrient, and plants absorb more nitrogen than any other element. Nitrogen is essential to in making sure plants are healthy as they develop and nutritious to eat after they’re harvested. Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.
