Answer:
B) Hydrogen Bond
Explanation:
Those are the bonds that the restrictive enzymes unzip and the bonds that hold the complementary bases.
The correct answer to your question would be B, Non sense mutation. Hope this helps you out let me know.
Answer:
here are the things you won't find in animal cells
Explanation:
cell wall, chloroplast, central vacuole, leucoplast, chromoplast,
Answer:
1. Auxins is a plant hormone that plays role in the differentiation of vascular tissue, stimulates the release of ethylene, prevention of abscission, controls cellular elongation, and enhances fruit development. Cytokinin plays an important role in cell division, delay senescence, and activating dormant buds in plants. The function of ethylene hormone in plants is in fruit ripening, promoting abscission. Gibberellins stimulate pollen tube growth, cause elongation of stems, initiate mobilization of storage materials in seeds during germination.
2. During transpiration, water is pulled from the roots to the leaves through a tissue called the xylem. As water evaporates out of the leaf, more water is 'pulled upwards' to replace lost water.
3. The stomata in the leaves are surrounded by guard cells. They can regulate the rate of transpiration by opening and closing the stomata.
4.During pressure flow, the sugar is transported from leaves to roots and phloem cells through the phloem via active transport.
5.
Phototropism refers to the growth of a plant in response to a light stimulus.
Example: Sunflowers -- flowers turn to face with the sunlight.
Geotropism is a process in which plant grows in response to gravity.
Example: Roots -- grow downward in response to gravity
Thigmotropism is the directional response of a plant organ to physical contact with a solid object.
Example: the growth of ivy on walls -- upon contact to walls
