The different shaped teeth allows our mouth to break down food better. For example our canines are used to rip sturdy foods like meat.

Choose one type of water pollution. How did the pollution happen? What negative effects does it have on the environment? What is

vivado [14]

Oil spill or a discharge from pipe from a factory or sewage system. Since this is a single point of origin water pollution, this type of water pollution furnish itself to relatively easy remediation.

What is point source water pollution?

Point-source water pollution is the one type of water pollution which is easy to recognize because it generates from a single source or event and affects a specific area.

The negative effects of single point origin is deteriorating water quality which damage the environment, health conditions.

Destruction of biodiversity is another negative effect of water pollution depletes aquatic ecosystems and prompt unbridled proliferation of phytoplankton in lakes called as eutrophication.

The solution to reduce water pollution is reduce carbon dioxide emissions to prevent global warming and acidification of the oceans. Another is to reduce the use of chemical pesticides and nutrients on crops.

1.Write the equation for light dependent reaction of photosynthesis

Annette [7]

Answer:

1. The overall chemical equation of the light-dependent reactions is given below:

12 H₂O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll ----> 6 O₂ + 12 NADPH + 18 ATP

2. The overall chemical equation for the light-independent reactions of the Calvin cycle is given below :

3 CO₂+ 6 NADPH + 5 H₂O + 9 ATP → glyceraldehyde-3-phosphate (G3P) + 2 H+ + 6 NADP+ + 9 ADP + 8 Pi

Explanation:

1. The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH which are used light-independent reactions to drive the synthesis of sugar molecules from inorganic CO₂ and water. Light-dependent reactions takes place in photosystem I and II. Photosystem I and Photosystem II ( PS I and PS II) are the two biochemical systems, active in chloroplasts, that serve as sites of electron transfer reactions in photosynthesis. Energy from sunlight is used to split water which releases electrons and hydrogen atoms which are transferred to NADP+ to produce ATP and NADPH and oxygen is produced as a waste product.

The overall chemical equation of the light-dependent reactions is given below:

12 H₂O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll ----> 6 O₂ + 12 NADPH + 18 ATP. Note that Pi refers to inorganic phosphate

2. The Calvin cycle refers to the light-independent reactions in photosynthesis. It occurs in three stages.

Stage 1 (Carbon fixation): In this first stage of the Calvin cycle, light-independent CO₂ is fixed by enzyme called ribulose bisphosphate carboxylase (RuBisCO) to ribulose bisphosphate (RuBP) to form glyceraldehyde-3-phosphate.

Stage2: ATP and NADPH are used to reduce 3-phosphoglycerate (3-PGA) into glyceraldehyde--phosphate (G3P). ATP and NADPH are used up in the process and are converted to ADP and NADP+, respectively.

Third stage: RuBP is regenerated, which enables the system to prepare for more CO2 to be fixed.

The overall chemical equation for the light-independent reactions of the Calvin cycle is given below :

3 CO₂+ 6 NADPH + 5 H₂O + 9 ATP → glyceraldehyde-3-phosphate (G3P) + 2 H+ + 6 NADP+ + 9 ADP + 8 Pi

Which organelle is responsible for actually making proteins?

yuradex [85]

Ribosomes
Ribosomes and Endoplasmic Reticulum
Ribosomes are the organelles responsible for protein translation and are composed of ribosomal RNA (rRNA) and proteins. Some ribosomes are found in the cytoplasm, a gel-like substance that organelles float in and some are found in the rough endoplasmic reticulum.
Hope this helped.
