The majority of B-vitamin deficiencies in today's world can be associated with consuming alcohol and cooking  

<u>Explanation:</u>

Vitamin B is most essential to be consumed for the metabolic processes and they are very delicate. Over cooking easily takes away the Vitamin-B from the food. Alcohol when consumed takes away all the vitamin-B from the kidney.

Hence majority of B-vitamin deficiency is caused by consuming alcohol and over cooking. It is important to have a food that is rich in vitamins and normally Vitamin-B is used for cell health and keep our body energetic.

Neurons in the parasympathetic pathway use which neurotransmitters?
Kay [80]
<h2>Acetylcholine</h2>

Explanation:

  • Acetylcholine is a chemical that is found between the nerve synapses, or gaps, between nerve cells. When activated, it causes the contraction of skeletal muscles and activates glandular functions in the endocrine system. Think of acetylcholine as a mailperson; residents cannot receive their mail until he or she comes and delivers it to the mailbox. Like mailpersons who deliver the mail and move on to the next house, acetylcholine acts quickly and does not hang around. As a result, acetylcholine is rapidly broken down by another chemical substance called cholinesterase.
  • Acetylcholine was the first neurotransmitter scientists discovered, as well as the most abundant neurotransmitter in the body. A neurotransmitter is a chemical that is released by a neuron, or nerve cell, that sends a signal to another neuron across a synapse. The neurotransmitter binds to receptors to affect how the signal is received. The purpose of the neurotransmitter is to either amplify or inhibit the signals sent between the neurons.
  • Acetylcholine plays an important role in the signal of muscle movement, sensation of pain, learning and memory formation, the regulation of the endocrine system and rapid eye movement (REM) sleep cycles.

Which characteristic do all protists have?
myrzilka [38]

Answer: They all survive in any environment.

Explanation: Protists have the ability to survive in any environment, even extreme environment. They can live in the ocean, desert or extremely hot environment, or even a extremely cold environment.

I'll explain why the others aren't correct.

Protists can be both unicellular and multicellular, they're not always unicellular. Kingdom Protista contains all eukaryotics, so they're not always unicelluar.

Protist cannot make or consume food. Animals consume food, and plants make food, not protista. Yes they're many plant-like protists out there, such as algae, they get their food from the sun above. So all protists cannot make or consume food.

Protist does have flagella, but not all protists. Protists that are motile and generate movement have flagella, meaning they move. Not all protist move, like plants can't move. So, not all protists have flagella, meaning they can move.

Let me know if you have any questions.

What is still lacking in the hypothesis of an asteroid impact as the cause of the end-cretaceous mass extinction?
Doss [256]

A convincing explanation of why some lineages survived while others vanished is still lacking in the hypothesis of an asteroid impact as the cause of the end-cretaceous mass extinction.

<h3>What is an asteroid?</h3>

One of the smaller planets in the inner Solar System is an asteroid. Asteroids are metallic or rocky bodies without an atmosphere, ranging in size from 1-meter pebbles to a dwarf planet with a diameter of over 1000 km.

The majority of the one million or more known asteroids are concentrated in the main asteroid belt, which is 2 to 4 AU from the Sun and between the orbits of Mars and Jupiter. The three categories of asteroids that are typically recognized are C-type, M-type, and S-type.

These were given their names and are frequently associated with, respectively, carbonaceous, metallic, and silicaceous compositions. The largest asteroid, Ceres, has a diameter of over 1,000 km (600 mi), making it a dwarf planet.
