1.The process of leaf color change. Leaves change color during the autumn because the amounts of pigments change as the leaves prepare to fall from trees. All leaves gradually lose chlorophyll during the growing season, and this loss accelerates before leaf fall.
2.The leaves in hot or dry environments may be adapted to reduce transpiration. For example, their stomata may be open at night and close midday. This is the reverse of what usually happens, and it means that the stomata are closet when the rate of transpiration would be greatest.
It's high sensitivity I believe
<span>In vitro fertilization
Not much to say, the question pretty much defines the technique. The first successful birth via IVF happened with the birth of Louise Brown in 1978. There are some issues with IVF that can cause complications. Among them are multiple births (twins or triplets) due to multiple blastocysts successfully implanting in the woman's uterus.</span>
Answer:
Viruses replicate only inside host cells.
Explanation:
<u>Viruses are not used as evidence to support the cell theory because they are not considered a cell and cannot carry out vital life processes without getting into host cells. </u>
According to the cell theory, the cell is the basic unit of life, all living organisms are made up of cells and cells arose from preexisting cells. A virus that is not in a host cell is just a piece of DNA/RNA surrounded by a protein coat and is not capable of carrying out any life process for it to be considered living.
<em>Viruses are only able to reproduce and multiply when they get access to a living host. They use the genetic mechanisms of the host to replicate their DNA/RNA using the lytic or lysogenic cycle. Hence, they are not used to support the cell theory. </em>
The answer is called the foramen ovale. Hope this helps.
