Answer:

The valves in the heart pump the blood around the body. When you feel your heart beating, that's the valves opening and closing.

Answer: The answer is C!!! :D maintaining homeostasis by regulating the body's temp!

Explanation:

Shivering as a natural, involuntary response to generate heat is an example of maintaining homeostasis by regulating body temperature.

Homeostasis refers to the maintenance of a relatively constant body environment. The normal range of operation of the body system is known as the setpoint.

When the setpoint temperature for some animals is breached, a negative feedback mechanism is used to return it to the setpoint. Shivering to generate heat is a response to a cold environment when the body's temperature is about to drop below the setpoint.

The oppositeis sweating. Sweating causes cooling and comes in response to when the setpoint temperature is exceeded.

Hopes this helps happy early Christmas!!!! :D

How is adp converted to atp?

Georgia [21]

ADP and ATP move pretty much in a cycle. ADP is converted to ATP by the weak bond formed between the ADP molecule and a third phosphate group. ATP moves to ADP by the removal of that weakly bonded phosphate group.

sleet_krkn [62]

Answer:

The correct answer is "All of these are fixed patterns".

Explanation:

Fixed action patterns are instinctive programmed responses in different species that are triggered by a specific external sensory stimulus. These stimuli are called sign stimuli. When the sign occurs, the animal starts a sequence of acts in response to the stimulus and continuous until the series of actions is completed. If the animal is interrupted for some reason, it continues its job from where it was interrupted; either the original stimulus is or is not present.

A chick’s gaping mouth induces a feeding response in a parent bird: The stimulus is the gaping mouth, which makes the parents to instinctually respond foraging more and feeding the chick.

A male fruit fly waves his wings at a female fruit fly during courtship: In courtship, the original stimulus is the presence of the female. One of the male´s responses actions is the wave of its wings.

A baby garter snake captures and eats a slug: For the baby snake, the sign stimulus is the slug scent. The snake then responses by capturing and eating the slug.

A European cuckoo hatchling pushes the host bird's egg out of the nest: The stimulus for the cuckoo chick is the presence of the host bird´s egg. When the cuckoo bird emerges from its egg, even before it opens its eyes, it pushes the host out of the nest.
