The energy animals need for their life functions is released when their cells carry out which of the following functions
Vlad [161]

Cellular respiration

Explanation:

The energy animals need for their life functions are released when their cells carry out cellular respiration.

Cellular respiration is a metabolic process by which living organisms breaks down organic molecules using oxygen  especially glucose to produce energy and gives off carbon dioxide and water in the process.

It is the reverse of photosynthesis.

During this process, chemical energy stored in food substances are released and converted to heat energy.

The process takes place in the mitochondria of a cell.

which microorganism present in the intestine of human and animals help in the synthesis and digestion of variety of foods ( plea
Soloha48 [4]

Answer:

Gut microflora is a combination of many different kinds of bacteria. Out of these, Lactobacillus bacteria, specifically, <em>Lactobacillius acidophilus</em> and <em>Lactobacillus bulgaricus </em>primarily help in the digestion of the milk sugar lactose. Probiotic bacteria in the gut microbiota, primarily, Lactobacillus and Bifidobacterium help in the synthesis of vitamins.

Explanation:

Gut Microbiota:

Gut microbiota are the microorganisms that live inside the gastrointestinal tract and aid in various body functions. Also called commensal flora, many of these help in digestion and biosyntheisis of vitamins.

  • Lactobacillus species are a predominant component of gut microbiota. Lactobacillus produces an enzyme called lactase that breaks down lactose sugar in milk.
  • Complex sugars in vegetables and fruits are broken down, mostly, by gut microbiota.
  • Probiotic bacteria, Lactobacillus and Bifidobacterium species aid the biosynthesis of various vitamins and nutrients such as:
  • Vitamin K and most of the water‐soluble B vitamins, such as biotin, cobalamin, folates, nicotinic acid, panthotenic acid, pyridoxine, riboflavin, and thiamine.

What is the BEST example of Newton's 1st law of motion?
Alla [95]

Answer:

All objects that have balanced forces acting on them must be stationary is an example of Newton's first law of motion.

Explanation:

  • Newton's First law of motion is the Law of inertia, that states a body continues to be in state opf rest or state of motion untill an unbalanced force acts on it.
  • So if a body has all balanced forces acting on it then it will continue to remain in state of rest i.e. it will be stationary.
  • The first example describes Newton's third law, that every action has equal and opposite reaction.
  • The second and third example supports Newton's Second Law, the law of momentum which states that the rate of change oif momentum is directly proportional to the force applied on the body and the mass of the body.
