Explanation:
Owl has the role of the tertiary (third) consumer, in above food web.
Phloem is the food conducting tissue that has a two-way flow.
Explanation:
Plants prepare food on their own and plants also have conductive cells that carry out transportation process. Plants are divided into two types based on their conductive system i.) vascular plants ii.) non vascular plants.
Vascular plants are those plants which have special conductive cells called phloem and xylem.
Xylem transports water from roots of the plants to other parts of plants and also provides mechanical support to plant. It is uni-directional.
Phloem is the food conducting tissue that transports food to plant and also have bi-directional movement.
The answer is pheromones. Hope that helps :)
Answer:
100% of the progeny will be speckled
Explanation:
<u>Available data:</u>
- Three colors: dark brown, light brown, and speckled.
- The genotypes for these colors are BB for dark brown, bb for light
brown, and Bb for speckled.
Cross: dark brown crab with a light brown crab
Parentals) BB x bb
Gametes) B B b b
Punnett square)
B B
b Bb Bb
b Bb Bb
F1) Genotype:
4/4 = 100% of the progeny will be heterozygous for the trait, Bb
Phenotype:
4/4 = 100% of the progeny will be speckled
