Answer:

Question 1: B the food web

They are all connected because they all depend on one another in order to survive.

Question 2: C. Dirt, water, pebbles, worms, and beans seeds

contains a living habitat, or ecosytem. This habitat might include plants, fungi, lichens, isopods (such as pill bugs), beetles, spiders, earthworms, amphibians (such as salamanders), reptiles (such as turtles), crickets, and more. Before you start: Having a terrarium is a responsibility.

Question 3: B. Grass

Plants or other photosynthetic organisms (autotrophs) are found on the first trophic level, at the bottom of the pyramid. The next level will be the herbivores, and then the carnivores that eat the herbivores. The energy pyramid (Figure below) shows four levels of a food chain, from producers to carnivores.

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

In corn plants, plant height is controlled by one gene with two alleles how many alleles that control the trait for height are p

Vesna [10]

Answer: 2 alleles

The number of the allele that a gene contains could be various. The allele will determine the phenotype of the organism, so more allele means more possible combination. There is only 1 gene that control the corn height and that gene only has two alleles. So, the total allele that controls the corn height should be: 1 gene * 2 alleles/gene= 2 alleles
