Explanation:
- The gardener plants only seeds of last year's largest vegetables because he knows that these seeds grows larger like their previous generation.
- For more profit he plants only them .
Answer:
Transpiration:
Losing the water absorbed by the plant through its aerial parts in the form of water vapor to the atmosphere. Water is absorbed by roots from the soil and transported as a liquid to the leaves via the xylem to mesophyll cells, through intercellular spaces, and moving through substomatal space to the stoma. The leaves and aerial parts have small pores that allow water to moves as a vapor.
Advantages:
With the transpiration exchange of gases also takes place.
Excess amount of water removed from the plant body.
Absorbing water and distribution of water among plant body parts
Cooling the exposed aerial parts of the plant to the sun and warm winds.
The osmotic balance of the plant cell is regulated by the process of transpiration.
The logical sequence in order to loss of water due to transpiration is as follows:
xylem, mesophyll cells, intercellular spaces, substomatal space, stoma.
Answer:
d. 2x.
Explanation:
At metaphase the DNA chromatides are duplicated. This explains that if in G1 phase of the cell cycle the DNA content is x, then the content in metaphase of meiosis I is 2x.
Answer:
The electron transport chain is the first step in cellular respiration. The reactions that generate the largest amounts of ATP during cellular respiration take place in the mitochondria.
Explanation:
conduction is solid
convection is liquid
radiation is anything that passes radiation
