I think the correct answer would be phloem. The vascular tissue that helps in the growth of the underground vegetable is the phloem. It is the tissue in a plant that conducts sugars and other products downward from the leaves.

Beetroot plant stores food in its root. underground tap root is modified into a bulb like structure which is used as vegetable and salad. Modified beetroot stores starch and water. therefore, tissues which conducts food and water are involved in the growth of beet root. Conducting tissue phloem which conducts food and xylem which conducts water are involved in growth of beetroot.

Paul [167]

Answer:

frequency of the blue (B) allele = 0.4142

frequency of the red (R) allele = 0.5858

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97

Explanation:

Frequency of blue allele is

Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

\frac{302}{2970} + \frac{1}{2} \frac{1857}{2970} \\= 0.1016 + 0.3126\\= 0.4142

Frequency of other allele

1- 0.4142\\= 0.5858

The snake contains 1,000 joules of energy. How much energy will the hawk effectively use upon eating the snake?
labwork [276]
Only 10% of the energy is transferred from one level to other,
so,
10% of 1,000J = 100 J
Which means 1000-100 = 900J of energy is used upon eating the snake.
(I’m not 100% sure about this answer though, but I think it will give u a good idea about energy transfer)
