Its more logical to say a leaf tissue because of the presence of several tissues inside it which are performing their designated functions.
<h3><u>Explanation:</u></h3>
If we look at the cross section of a leaf, the leaf tissue looks having several tissues. There are vascular bundles in the midrib that are xylem and phloem. Then there are leaf parenchyma which contains the chloroplasts.
They are palisade parenchyma on upper layer and spongy parenchyma. Then there are leaf epidermis on both upper and lower surfaces of leaf. So because of the presence of different tissues, they are collectively called as leaf tissue.
Answer:
<em>The water will diffuse into the air.</em>
Explanation:
Diffusion can be described as a process through which molecules travel from an area of higher concentration to an area of lower concentration along the concentration gradient. Such processes do not require energy. As the concentration of water is less in the air surrounding the cell as compared to the inside of the cell hence, the water molecules will move out of the vacuole and into the air by the process of diffusion.
Answer:
One astronomical unit is the approximate mean distance between the Earth and sun. It's about 93 million miles (150 million km), or 8 light-minutes. Enjoying ...
Explanation:
Image result for he distance between the Earth and the sun is about 93 million miles. To reduce the difficulties of dealing with the large numbers of these distances scientists have designated the distance from the Earth to the sun as one (blank) or AU aphelion Half a year after perihelion, Earth reaches its farthest distance from the star, which is called aphelion. At that moment, the planet is approximately 94.5 million miles (152.1 million km) from the sun. Aphelion occurs in early July. Perihelion and aphelion average out to about 93 million miles (150 million km).
