Describe what you think is happening during photosynthesis.
boyakko [2]

Answer:

During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Explanation:

The energy for photosynthesis comes from light. Light energy is converted to chemical energy by chlorophyll. There are two sets of reactions, light dependent and light independent. The process mostly takes place in the chloroplasts of plant leaf mesophyll cells. Photosynthesis is the process where a plants uses the sun’s energy to turn light into chlorophyll. Plants produce oxygen during this process and utilize carbon dioxide. Photosynthesis is the single most important chemical process on the earth. Almost all plants needs the sun in order to survive Photosynthesis is the most important chemical process on earth – it provides food and energy for all living creatures who eat the plants that rely on this process to produce their food (glucose). · More than half (70%) of the world’s oxygen is produced by phytoplankton photosynthesis in the world’s oceans.

Amniocentesis and chorionic villus sampling allow for ________ and ________ of the fetus so that it can be tested for abnormalit
max2010maxim [7]

The fetus can be screened for abnormalities using karyotyping and biochemical analysis using amniocentesis and chorionic villus sample.

<h3>What data can we glean from CVS and amniocentesis?</h3>

In at-risk fetuses, these tests can detect genetic illnesses such cystic fibrosis, Tay-Sachs disease, and sickle cell disease. The main benefit of CVS over amniocentesis is that it is done considerably earlier in pregnancy—at 10 to 13 weeks as opposed to 15 to 20 weeks—thus saving more time for the mother.

<h3>What can a couple learn about their growing fetus from amniocentesis and chorionic villus sampling?</h3>

Amniocentesis and chorionic villus sampling (CVS) are prenatal diagnostic techniques used to identify certain fetal genetic disorders. The likelihood of miscarriage rises with both procedures.
