Biology
1 answer:
MArishka [77]3 years ago
6 0

Answer:

The sequence is b, a, d, c.

Explanation:

Pulmonary ventilation may be defined as be defined as the simple process of intake of oxygen and exhale of carbon dioxide known as breathing. Diaphragm contracts during inspiration and relax during exhalation.

The pulomonary ventilation occurs when the skeletal muscle contraction occur by the stimulation from the brainstem nuclei. This leads to the changes in the volume of the thoracic cavity. The thorax changes its shape by contraction and relaxation, this leads to the pressure change. Then air flows down the pressure gradient.

Thus, the correct sequence is  b, a, d, c.

The hindbrain of the embryo develops into the pons, the medulla oblongata, part of the spinal cord, and what other structure?
Zepler [3.9K]

The hindbrain of the embryo develops into the pons, the medulla oblongata of the spinal cord and the cerebellum.

<h3>What is the cerebellum? </h3>

The cerebellum is a prominent part of the hindbrain and is located just above the brainstem. The cerebellum controls all the voluntary movements of the body and is also responsible for maintaining balance and posture.

The cerebellum is said to make up for 10% of the brain's volume but has more than 50% of the brain's total neurons.

The cerebellum is made up of two parts; a cerebral cortex, a layer made of folded tissue which contains most of the neurons and cerebral nuclei, an inner part which contains the neurons responsible for communication.

Therefore, the hindbrain develops into the pons, medulla oblongata and cerebellum.

Domestic cattle often have interactions with wild animals. In South America,
scZoUnD [109]

Answer:

Bats are the only mammals that can fly, but vampire bats have an even more interesting distinction—they are the only mammals that feed entirely on blood.

Nocturnal Behavior

These notorious bats sleep during the day in total darkness, suspended upside down from the roofs of caves. They typically gather in colonies of about 100 animals, but sometimes live in groups of 1,000 or more. In one year, a 100-bat colony can drink the blood of 25 cows.

During the darkest part of the night, common vampire bats emerge to hunt. Sleeping cattle and horses are their usual victims, but they have been known to feed on people as well. The bats drink their victim's blood for about 30 minutes. They don't remove enough blood to harm their host, but their bites can cause nasty infections and disease.

Hunting for Blood

Vampire bats strike their victims from the ground. They land near their prey and approach it on all fours. The bats have few teeth because of their liquid diet, but those they have are razor sharp. Each bat has a heat sensor on its nose that points it toward a spot where warm blood is flowing just beneath its victim's skin. After putting the bite on an animal, the vampire bat laps up the flowing blood with its tongue. Its saliva prevents the blood from clotting.

Young vampire bats feed not on blood but on milk. They cling tightly to their mothers, even in flight, and consume nothing but her milk for about three months.

The common vampire bat is found in the tropics of Mexico, Central America, and South America.

Hope it helps!
