Explanation:

We know that the disease is caused by the SARS-CoV-2 virus, which spreads between people in several different ways. The virus can spread from an infected person's mouth or nose in small liquid particles when they cough, sneeze, speak, sing or breathe.

Explanation:

-The increased light intensity increased the rate of photosynthesis.

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water. Since photosynthesis is rate limited, the rate of energy intake can be increased in order to speed up photosynthesis, by speeding up photolysis.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

These end products, namely O2 and glucose are then used in respiration...

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

The CO2 and H2O produced as waste in respiration can then be incorporated at the beginning of photosynthesis. Thus the reactions are cyclic- they feed into each other.

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Respiration and photorespiration both utilize oxygen for;

the production of ATP via the oxidization of pyruvate;
and the oxygenation of the molecule Ribulose 1,5-bisphosphate (RuBP), an organic molecule also used in photosynthesis, to form 3-PGA + phosphoglycolic acid,

∴ the rate of CO2 usage for photosynthesis where O2 is produced, outpaces the rate of O2 use in respiration and photorespiration.

What 2 enzymes are used during DNA replication? describe what each does during replication

polet [3.4K]

The two enzymes that are used during DNA replication is helicase and polymerase. Each enzyme has distinct role that made it a vital part of the replication. In the course of DNA replication, the initial stage is to unzip the double helix structure of the DNA molecule by the enzyme helicase, which breaks the hydrogen bonds that holds the complementary bases of DNA.

Moreover, the DNA polymerase has the ability to exactly copy a DNA template. This enzyme binds to the leading strand and then adding a new complementary nucleotide bases to the DNA strand. In addition, it catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the increasing DNA chain.

Why does our body need a defense system ?

algol [13]

Answer:

Explanation:

You have external defense systems, which include your skin, tears, mucus, saliva, stomach acid, cilia (small hairs) and helpful bacteria. ... The skin stops pathogens from entering the blood, at least when you're not bleeding. The tears, mucus, and cilia trap them and help push them back out of your body.

Answer:

Sleep apnea.

Explanation:

Sleep apnea:

Sleep apnea is considered as serious sleep disorder in which patient's breathing during sleep repeatedly stop and start along with snoring.

So, here the scenario that Sarah's grandfather is suffering from sleep apnea because he takes nap on recliner and suddenly stop snoring and stop breathing and again resume the breathing along with snoring.
