The right answer is D
The stomata are at the level of the epidermis of the leaves and aerial stems, the place of passage of the gases (carbon dioxide, oxygen, water vapor) which play a fundamental role in the physiology of the plant. These structures (which can be considered as "mini-organs") interactively regulate these exchanges. They are the terrestrial plants that constitute the true interface between the external atmosphere and the internal gas network.
Answer:
If the scull is fused the individual is not a baby
Explanation:
If a skull is found, one of the first things to do is classify by age. Careful observation will show that the skull may or may not be fused. Noteworthy observations could give the professional an idea of the individual's age.
In the womb when the bones of the skull are being formed thre are typically seven bones with gaps in between. This allows the infant to pass safely through the birth canal but giving way to squeezing and the contractions of the uterus. After the child is born there are still remaining gaps. These gaps allow the brain to grow and develop without pressure from the skull. This can often be observed by a soft spot on the top of the infant's head sometimes called a "mole"
Around two years of age, these bones begin to fuse and harden. Therefore if a skull is found with fused bones, the individual can be placed to be older than two years of age. Other determining factors such as teeth etc can narrow down the individual's age.
Once entering the atmosphere the heated up water vapor (that's the process of evaporation) cools back down (the atmosphere is cooler than the Earth you see). it makes clouds Their it will condense until it's heavy enough to fall to Earth as precipitation!
Explanation: Electron microscopes are the most powerful type of microscope, capable of distinguishing even individual atoms. However, these microscopes cannot be used to image living cells because the electrons destroy the samples.
To describe a scientist as skeptical, they question existing ideas and a new hypothesis. skepticism is a valuable quality because it shows that scientists is good and open minded.
