Binocular vision, the ability to focus both eyes on the same object at the same time, usually does not develop until 4-5 months of age.
Binocular vision is the type of vision in which both the eyes look in the same direction to form a 3-D image of the object. One single image is formed by both the eyes. When any disorder appears regarding the binocular vision, the core reason is the misalignment of both the eyes.
Eyes are the organs of vision. They are present in a pair embedded in a socket like region on the skeleton below the forehead. The image is formed at the retina of the eye. The image formed is an upside down image.

Explanation:
it going to a residential area to the water shed meaning that the only possible correct answer.
Calcium levels in the body are maintained by hormones. If the blood calcium level rises above a set point, calcitonin is secreted by the thyroid gland and sets into motion responses to lower the blood calcium back to the set point. If the blood calcium level falls below a set point, the parathyroid gland secretes parathyroid hormone that sets into motion responses to raise the blood calcium. These homeostatic responses are examples of:
a. positive feedback
b. effectors
c. sensors
d. negative feedback
Answer:
d. negative feedback
Explanation:
Negative feedback responses are the ones that counteract the change. Any alterations in the internal body conditions such as blood calcium levels are sensed by receptors. The information is sent to the brain which in turn commands the effectors such as endocrine glands to secrete the required hormones to restore the normal conditions. Here, changes in the calcium levels are counteracted by the secretion of calcitonin and parathyroid hormones and the calcium is maintained within a narrow range. This represents negative feedback.
