There are many lines of evidence which clearly show that the atmospheric CO2<span>increase is caused by humans.  The clearest of these is simple accounting - humans are emitting CO2 at a rate twice as fast as the atmospheric increase (natural sinks are absorbing the other half).  There is no question whatsoever that the CO2 increase is human-caused.  This is settled science.</span>

name two major vessels that return oxygen-poor blood to the heart. What are the damages for each? Where do they terminate?
Serga [27]

Answer:

1. Head, neck, upper limb, thorax - super vena cava - top of the right atrium.

2. Lower limb - inferior vena cava - bottom of the right atrium.

Explanation:

The Heart pumps the oxygen-rich blood to the different parts of the body to Otake oxygen and nutrients to these organs and then takes the oxygen-poor blood returns from the body to the heart.

The two major vessels that return oxygen-poor blood to the heart are 1. superior vena cava (SVC) that drainages Head, neck, upper limb, thorax and terminate at top of the right atrium, and 2. inferior vena cava (IVC), Lower limb and terminate at bottom of the right atrium.

1. Head, neck, upper limb, thorax - super vena cava - top of the right atrium.

2. Lower limb - inferior vena cava - bottom of the right atrium.

ALL BUT one product of the light dependent reaction of photosynthesis is utilized in the light independent reaction. That is
Lesechka [4]

Answer: Oxygen

Explanation: Photosynthesis is a process by which plants use carbon dioxide, water and sunlight to produce glucose and oxygen.

Photosynthetic reactions are divided into two phases: 1). light dependent reactions and 2). light independent reactions.

1) In light dependent reactions, chlorophyll and other light absorbing pigments absorb light energy and conserve it as ATP and NADPH with the simultaneous liberation of oxygen. This reaction occurs only when plants are illuminated. In light reactions, light energy is used to split water molecules into hydrogen ions and oxygen, the hydrogen ions produced are transferred to NADP+ to form NADPH, ATP is also produced in light dependent reactions.

2) In light independent reactions, ATP and NADPH produced in the light dependent reactions are used to drive the light independent reactions in which ATP and NADPH are used to reduce CO2 to form trioses, starch, sucrose and other products derived from them.
