Guard cells use osmotic pressure to open and close stomata, allowing plants to regulate the amount of water and solutes within them. In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis
The answer is C because if a doctor only tested new medication on one person then gave it to many other people with the same disease there might have been a mistake and could kill people
Answer:
d. None of these
Explanation:
Probably the identical sequence found in both species<em> </em>is an<em> ultraconserved sequence. </em>
An <u>ultraconserved element</u> is a particular DNI sequence that remains exactly the same through evolution, with almost no modification, and that is shared by at least two completely different species.
These ultraconserved DNI portions seem to be highly essential for life. However, their function could not be determined yet. Most of them do not codify for proteins, but they could play a significant role in gene regulation.
It is suggested that these sequences are so significant for life that only a small change would compromise the organism´s aptitude.
Answer:
In which phase of mitosis do chromosomes align at the center and spindle fibers become visible? Explanation: Mitosis involves four distinct stages: prophase, metaphase, anaphase, and telophase. Prophase is the first step of mitosis, during which chromosomes condense and the nuclear envelope dissolves.
