We're getting near Halloween and it seems everywhere you turn is something creepy and spooky. Bats are a common symbol of Halloween, so it seemed appropriate to cover them in the Animal Hearing Series.

Most people have heard of bats' ability ofecholocation. It's a natural type of sonar. Bats use it to navigate, hunt and find spots to roost. To perform echolocation, a bat makes a loud sound, and then measures the time it takes for the sound to bounce back to determine how far away things are. They can also tell what they're near to by the sound quality of the echo they hear.

Because they use echolocation to get around and can't use their eyesight much while hunting, you'd think bats would need to have very good hearing. And they certainly do. They can hear between 20 to 120,000 Hz. They are very sensitive to high-frequency sounds, way beyond what humans can hear. Even the shape of bats' ears contribute to being able to hear better.

givi [52]

Answer:

The answers are letters B and C.

Explanation:

The differences between Braxton Hicks contractions and true labor are:

1. The braxton hicks contractions do not follow a consisten pattern, while the real contractions last around 30 to 70 seconds and repeat the same intervals.

2. Increasing frequency: The true labor happens after the increase of the real contractions frequency, meanwhile the braxton hicks don't increase in frequency.

3. Intensity: the real contractions are way more painful than the braxton hicks. The braxton hicks contractions are not painfully mostly.

4. Location of discomfort: the true labor causes back pain, lower back pain that can spread to the legs. Braxton-hicks only causes abdominal pain, in the front. In addition, changing positions and movement can stop the braxton hicks contraction. In a true labor, movement do not stop the real contractions.

Describe how insight impairment can affect a person's behaviour

uranmaximum [27]

The person might poke or press his eyes, gaze at lights, flap with hands. Aggressive behavior is also common, such as pushing, biting, yelling, or hitting. They will try to be "normal", even going as far as denying that they have insight or, more commonly, visual impairment.
