Orange trees planted in a grove or orchard would most likely fall in which category of population distribution?

Why are plants green? In photosynthesis, chlorophyll molecules act as solar antennae, so that when sunlight strikes them their e

Anastasy [175]

Answer:

1. Plants are green due to presence of green pigment chlorophyll in their chloroplasts.

2. ATP is used to make organic sugars (glucose)

Explanation:

Chlorophyll pigments absorb the light in the blue and red regions and reflect all the green light. When the reflected green light reaches our eyes, the plants look green in color. The color of the object is determined by the color of the reflected light.

Splitting of water during the light-dependent phase of photosynthesis and electron transfer through cytochrome b6/f complex generates the proton concentration gradient which in turn drives the synthesis of ATP. Calvin cycle refers to the set of reactions that fix the atmospheric CO2 into organic sugars such as glucose. The ATP molecules formed during light reactions are used to drive the endergonic reactions of the Calvin cycle.

Relate restriction enzymes to recombinant DNA

kirza4 [7]

Answer:

Read the explanation section.

Explanation:

Restriction enzymes basically used in genetic engineering. Particularly in recombinant DNA technology. Restriction enzymes have two properties, which are very much useful in recombinant DNA technology.

First, they cut DNA into fragments or small pieces. This cutting is done to make the size of the DNA into a suitable one for cloning purposes.

Second, many restriction enzymes make staggered cuts that create single-stranded glutinous ends. These ends are favorable to the formation of recombinant DNA.

In humans, the embryonic and fetal forms of hemoglobin have a higher affinity for oxygen than that of adults. Why is this the ca

Bezzdna [24]

In humans, the embryonic and the fetal forms of haemoglobin have a higher affinity for oxygen than that of adults this is because non-identical genes produce different versions of globin during development. So the correct option is A.

<h3>What is meant by oxygen affinity? </h3><h3> </h3>

The amount of oxygen delivered to the cells will depend on the haemoglobin's oxygen affinity.

Oxygen affinity is defined as the relationship between the saturation of haemoglobin oxygen, represented by SaO2 and the oxygen tension, represented by PaO2. This relationship is plotted by a dissociation curve which is S-shaped.

Thus, in the embryonic the fetal form, haemoglobin has a higher affinity for oxygen.

Therefore the correct option is A.
