<h3>Meat consumption and environment</h3>

Explanation:

Increase in population rises protein demand. Many people meet their dietary protein requirements mainly from animal sources by consumption of meat and meat products like meat, eggs, and processed meat products.

Increased meat consumption leads to increase in global warming. Increased meat consumption raises the demand for meat and animal farming like cattle, poultry and fish farming.

Farm animals release methane through their waste into the environment. Methane is one of the most potential greenhouse gases that cause global warming.  

Animal farming practices requires a lot of water and hence depletes natural water sources. Moreover, the effluent drainage from farmlands pollutes the land as well as natural ground water sources with methane and other pollutants including pathogens and renders the natural sources unusable.

Further, farm animals like cows and goats grazes farmlands and destroys the green cover which helps in carbon sequestration.

Answer:

D

Explanation:

The functions of nucleic acids(DNA AND RNA) have to do with the storage and expression of genetic information. DNA encodes the information of the cell necessary to make proteins while the RNA participate in protein synthesis.

in experiment 1, which of the following factors was systematically changed so that its effects could be observed? A.light intens
Stels [109]

Explanation:

<u>A.light intensity</u>

<u />

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

Carbon dioxide + water + energy= glucose + oxygen

At the compensation point, the rate of CO2 production by respiration matches the rate of CO2 utilization in photosynthesis- there is no net CO2 production . Since photosynthesis is rate limited, the rate of energy intake can be reduced in order to reach the compensation point; lowering the light intensity would slow the rate of photolysis and thus photosynthesis. Similarly, an increase in light intensity

  • increases the rate of photosynthesis- the CO2 level would be reduced as more inorganic CO2 is fixed, together with producing O2 as waste.
  • would increase the temperature of the environment- light energy is converted to heat energy which increases temperature.
  • lead to higher levels of humidity- the heightened temperature increases the rate of evaporation of water from tissues, and thus increases the humidity (water vapor content of the surrounding air)

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.

Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain. This occurs in the thykaloids, where pigment molecules like chlorophyll reside. Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.

Why do cats purr?///////////////
jenyasd209 [6]

Answer:

Cats also purr when they are nervous or in pain, leading some experts to believe that this uniquely feline vocalization is actually a method of self-healing. A domestic cat's purr has a frequency of between 25 and 150 Hertz, which happens to be the frequency at which muscles and bones best grow and repair themselves.
