Answer:
Inspiration (breathing in)
The diaphragm contracts and moves downwards. The intercostal muscles contract and move the ribs upwards and outwards. This increases the size of the chest and decreases the air pressure inside it which sucks air into the lungs. During normal breathing, the major inspiratory muscles produce rib cage expansion and a downward movement of the diaphragm. These movements cause the pressure around and in the lung to become negative (relative to atmospheric pressure).
Explanation:
Explanation:
During normal breathing, contraction of the major inspiratory muscle, the diaphragm, produces both rib cage expansion and a downward movement of the diaphragm. These movements cause the pressure around and in the lung to become negative relative to atmosphere.

Is M. Tuberculosis a Eubacteria or Archaebacteria?
Answer:
MYCOBACTERIA. Mycobacteria are classified as Gram-positive bacteria, but they have features of both Gram-positive and Gram-negative organisms. Pathogenic mycobacteria include the organisms that cause tuberculosis and leprosy and are intracellular parasites, replicating within modified phagosomes of macrophages.
Explanation:
Answer:
As the spores germinate, they produce neurotoxins which, if ingested, leads to paralysis and either respiratory or cardiac failure. A very important disease-causing bacterium in the Western Cape is Mycobacterium tuberculosis, the bacterium that causes TB.

Explanation:
when people take a mineral and hold it up, what kind of test is that?
a) luster
b) cleavage
c) hardness
can someone plss help me??
Answer:
Luster
Explanation:
luster is the only answer that has to do with light. Luster is measured by the way a mineral reflects light.
Cleavage has to do with breaking minerals apart along certain fracture lines. Cleavage is not the answer.
Hardness is a test where one mineral is used to scratch another. The one that does the scratching is harder than the one that is scratched.

What type of RNA carries the genetic information from the Nucleus to the Ribosome?
The mRNA (messenger RNA) is the special type of RNA that transports the genetic information to the ribosomes.
What is mRNA?The messenger RNA (mRNA) is a special type of mRNA used to synthesize proteins by transcription and translation.
During gene transcription, a gene is used as a template strand and thus generates an mRNA.Subsequently, the mRNA molecule travels to the ribosomes where it will be used for protein synthesis.In conclusion, the mRNA (messenger RNA) is the RNA that transports the genetic information to the ribosomes.

How does the carbon cycle support the Law of Conservation of Mass?
The carbon cycle supports the Law of Conservation of Mass, as the law states, the carbon also reuse and reabsorb in the carbon cycle.
What is the carbon cycle?
The carbon cycle is the movement of carbon from the atmosphere to plants and organisms. Carbon is coal when burned turn into gas.
The majority of carbon is kept in rocks and sediments; the remainder is kept in the ocean, atmosphere, and living things.
According to the Law of Conservation of Matter, matter can be created or destruct. Because the carbon cycle recycles the same carbon atoms, it serves as an illustration of the Law. Some carbon is stored for future growth, and some are used for energy.
Thus, because carbon is reused and reabsorbed in the carbon cycle, the Law of Conservation of Mass is supported by this law.

A. The products of cellular respiration are the products of photosynthesis
B. The reactants of photosynthesis are the reactants of cellular respiration
C. The reactants and products of photosynthesis has no relationship with the reactants and products of cellular respiration
D. The products of cellular respiration are the reactants of photosynthesis
Answer:
B is the answer
Explanation:
The correct response regarding the relationship between photosynthesis and cellular respiration is The reactants of photosynthesis are the reactants of cellular respiration. The correct option is B.
What is photosynthesis?
Photosynthesis is a process of transforming solar energy into chemical energy, which is then stored for later use. The majority of the time, this mechanism powers the planet's life systems.
The process by which sugar is broken down in the presence of oxygen in the cell to release energy in the form of ATP is known as cellular respiration. Water and carbon dioxide are waste products of this process.
So, photosynthesis is a process of anabolism process of food which produces energy, and for cellular respiration, glucose is combined with oxygen to form energy.
Thus, the correct option is B.
