stellarik [79]

Answer:

  1. Glycine
  2. Ribulose 1,5-bisphosphate
  3. 3-phosphoglycerate
  4. Glyceraldehyde 3-phosphate.
  5. Glucose
  6. Sucrose

Explanation:

The glycine, among other amino acids, helps to improve chlorophyll production and promotes the process of photosynthesis.  

<u>Calvin cycle</u>

During the carbon fixation phase, a CO² molecule combinate with a ribulose 1,5-bisphosphate to form 6-carbonated molecules, which will divide into two 3-phosphoglycerate molecules.  

During the reduction phase, NADPH donates its electrons to reduce 3-phosphoglycerate molecules, and turn them into glyceraldehyde 3-phosphate.

During the regeneration phase, a glyceraldehyde 3-phosphate molecule leaves the cycle and goes to the cytosol to form glucose. This step can be done when three CO² enter the cycle and produce six glyceraldehyde 3-phosphate molecules. One of them leaves the cycle to form glucose, while the other five are recycled.

<u>Cytosol: </u>

Once in the cytosol, glyceraldehyde 3-phosphate molecules are used to form glucose and fructose. These two molecules are the monosaccharides that form the sucrose.

Once sucrose is formed, it is transported from the photosynthetic tissues to different parts of the plant by the phloem.

Which two body systems interact to expel the waste product carbon dioxide
Pani-rosa [81]

Answer:

excretory system  and circulatory system

Explanation:

Blood is  part of circulatory system and as it move through various organs it exchanges the gases i.e give oxygen to the cell and take carbon dioxide from them. After taking CO2, the  blood becomes impure and hence it passes through the kidney before going to the heart. Kidney is part of excretory system which removes carbon dioxide from blood and thus purifies it.

A student measured the mass and volume of a metal sample using a triple beam balance and a graduated cylinder. The sample has a
alexdok [17]

Answer:

d=3.79\ g/cm^3

Explanation:

Given that,

The mass of a sample, m = 16.7 grams

Volume of the sample, V = 4.4 cm³

We need to find the density of the metal sample.

Density = mass/volume

Substituting all the values,

d=\dfrac{16.7\ g}{4.4\ cm^3}\\\\=3.79\ g/cm^3

So, the density of the metal sample is 3.79\ g/cm^3.

Which enzymes are needed to produce recombinant plasmids to be used in gene transfer?
irina [24]
The answer is D. For producing recombinant, first you need to cut the insert part and vector part to get the same end by using restriction enzyme. Then using DNA ligase to bind these two parts to get a new plasmids.
