Answer:

Written below.

Explanation:

5. During meiosis, a reproductive cell and its nucleus divide twice and produce four cells––two pairs of identical haploid cells.

6. Homologous chromosomes are two pieces of DNA within a diploid organism that carry the same genes, one from each parental source. In simpler terms, both of your parents provide a complete genome. Each parent provides the same 23 chromosomes, which encode the same genes.

1. What is the Photosynthesis EQUATION? What is being consumed and what is produced?
Alla [95]
1. 6CO2 + H2O -----> C6H12O6 + 02

2. The idea of photosynthesis or light dependent reactions is to convert solar/light energy into chemical energy by the form of ATP and NADPH. CO2 and Water are consumed and react to release Glucose and 02. Approximately 36-38 ATP produced.

3. Water is the source of hydrogen atoms in the glucose (sugar) created by the photosynthesis reaction.

4 .
Step 1) The light absorbed by chlorophyll causes a transfer of electrons and H+ from H20 molecules already present. This causes the H20 to split into molecular 0xygen (02) and a H+ ion.

Step 2.) The O2 is released (we breathe it) and the H+ bonds to NADP+ creating NADPH

Step 3) ATP is formed through photophosphorylation. (ADP gets a phosphate group added to it creating ATP)

Step 4.) The NADPH and the ATP created here go on to fuel the reactions in the second part of photosynthesis - The Calvin Cycle

5. The Calvin cycle is a metabolic process that uses the carbon from carbon dioxide, along with energy in the form of ATP, to produce sugar.
A G3P molecule contains three fixed carbon atoms, so it takes two G3Ps to build a six-carbon glucose molecule. It would take six turns of the cycle.

6. To help synthesize carbohydrates for energy

7. In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADP +, respectively

The model below shows the Moon at one position in its orbit around Earth. The white half of the Moon represents the part of the
Furkat [3]

Answer: Although the Moon appears to shine, it does not emit light. Instead, we can see the Moon because it is lit up by the Sun.

Explanation:

The part of the Moon that is both sunlit and facing Earth is called the Moon's phase.

As the Moon orbits Earth, the Moon's phase changes. The model below shows the Moon's phase at eight positions in its orbit. The smaller moons closer to Earth show where sunlight hits the Moon. The larger moons farther from Earth show how the Moon will look during that phase.
