Answer and Explanation:
In some, the leaves are needle-like and stomata are reduced in number and located in cavities on the epidermis. A layer of moist air builds up in the cavity. This reduces the humidity difference between the intercellular air spaces in the leaf and the immediate external environment thus reducing the rate of transpiration.
In some the epidermis of the leaves is multilayered and is covered with a thick waxy cuticle which reduces water loss through evaporation, e.g. oleander. The cuticle is normally shiny which helps to reflect solar radiation preventing the leaf from heating up rapidly.
Answer:
Smooth & yellow: 9
smooth & green: 3
wrinkled & yellow: 3
wrinkled & green: 1
Explanation:
Gene controlling seed color are yellow Vs green
Gene controlling seed texture are smooth Vs wrinkled
In F1 generation, A true breeding smooth green plant (SSyy) is crossed to a true breeding wrinkled yellow (ssYY)
Off spring in F1 generation are smooth yellow (SsYy)
This means smooth texture is dominant over wrinkled texture and yellow color is dominant over green
in F2 generation, the cross is carried between SsYy
SY Sy sY sy
SY SSYY SSYy SsYY SsYy
Sy SSYy SSyy SsYy Ssyy
sY SsYY SsYy ssYY ssYy
sy SsYy Ssyy ssYy ssyy
Smooth & yellow: 9
smooth & green: 3
wrinkled & yellow: 3
wrinkled & green: 1
Adaptation is the correct answer
Answer:
Shear stress
Explanation:
Shear stress is a type of stress that occurs when a rock mass is pushed in parallel and opposite directions.
Answer:
- Human growth and functioning can be explained by the functioning of the cells.
- Cells are the fundamental units of humans.
- The functioning of the cells in the body determine human health.
Explanation:
The cell is the basic unit of life. Therefore the biochemical activities of the cell at a micro-level will definitely influence overall physiology at the macro level of an organism. For example, the production of Thyroid hormone at the molecular level by the cells in the thyroid glands will influence the metabolisms of all cells in a human being and therefore affect the organism’s overall growth and development.
