Answer:
The main role of chloroplasts is to conduct photosynthesis.
They convert light energy into relatively stable chemical energy via the photosynthetic process.

Hhv-5 infectious in pregnant women can be particular concern because this virus can be teratogenic.
<h3>
What is teratogenic?</h3>
- Teratology is the study of aberrant physiological development across the whole life cycle of all species, including plants.
- Dysmorphology is a branch of medical genetics that focuses on the classification of congenital deformities.
- Teratogens are substances that, when exposed to a pregnant woman, may result in physical or functional abnormalities in the human embryo or fetus.
- Such substances include, for example, alcohol and cocaine.
- A teratogen is an agent that increases a baby's risk of developing a birth defect or can actually cause one.
- They are items to which a mother might be exposed while expecting.
- Teratogens can result in neural tube abnormalities like spina bifida during this time.
- Throughout the entire pregnancy, certain organs are vulnerable to teratogens.
- The baby's brain and spinal cord are included in this.
- Alcohol can be harmful at any point during pregnancy since it has an adverse effect on the brain and spinal cord.

Flu vaccines need to be revised and changed every year because the flu virus constantly mutates. Flu viruses can change in two ways: drift or shift. Antigenic drift occurs when genes of the virus slowly change during replication until the immune system no longer recognizes it. On the other hand, antigenic shift occurs when a major change in the virus happens. This usually leads to a totally different kind of virus. This is what happened during the H1N1 scare in 2009.
DNA viruses like mumps are less prone to mutation due to the presence of DNA polymerase. RNA viruses are more prone to mutation because they undergo reverse transcription to simulate the role of DNA.
The guppies evolved at a rate between 3700 and 45,000 Darwin's. For comparison, artificial-selection experiments on mice show rates of up to 200,000 Darwin's while most rates measured in the fossil record are only 0.1 to 1.0 Darwin.
Guppies introduced to a low-predation environment adapted to their new environment by producing larger and fewer offspring with each reproductive cycle. No such adaptation was seen in guppies that colonized a high-predation
With each generation, more guppies passed on the gene for small spots to their offspring. The rocks became smaller. More guppies with small spots survived long enough to pass on the gene for small spots to their offspring the rocks became smaller.
