The correct answer option is C. textbook.
An online textbook or e-book is a digitally readable version of a physical textbook which is meant to be read on some digital device, for instance PC's. laptops,tablets, mobile phones, etc.
E-books, like physical textbooks, include text, images or both but require a digital medium to become readable. However, it is considered a drawback since to use an e-book, the user is dependable on the availability of some digital device.
Answer:
D
Explanation:
Enzymes are chemical catalysts they speed up/ increase the rate of the reaction by lowering the activation energy (minimum energy required for reaction to actually occur).
<h2>Mesophyll cells</h2>
Explanation:
The most distinctive characteristic of leaf mesophyll cells is that they are filled with many chloroplasts
Mesophyll cells constitute the main body of a leaf, occurring between upper and lower epidermis
Typically, the leaves of temperate-zone plants have two layers of mesophyll cells, the palisade mesophyll on the upper side and the spongy mesophyll on the lower side
The palisade mesophyll is a layer of densely packed, columnar cells which contain many chloroplasts, this layer is responsible for most of the photosynthesis of leaves
The spongy mesophyll is composed of large, often odd-shaped, photosynthetic cells separated from one another by large, intercellular spaces, these intercellular spaces apparently facilitate the exchange of photosynthetic gases
Answer:they convert light energy! they play a big part in photosynthesis
Explanation:
Parental Phenotypes: "Yellow-Smooth", "Yellow-Wrinkled", "Green-Smooth", "Green Wrinkled".
Parental Genotypes: SsGg × SsGg
Parental Gametes: SG, Sg, sG, sg
<span>
Smooth/Green </span>= S-G- = 9
<span>
Winkled/Green </span>= ssG- = 3
Smooth/Yellow = S-gg = 3
Wrinkled/Yellow = ssgg = 1
Ratio would be: 9: 3: 3: 1
Hope this helps!
