Answer:
I believe the answer is "A. They can both involve the transfer of thermal energy from one material to another."
Answer:
The Bees find the required nectar in the flower by the "sight as well as the odor and also they receive buzz from the floral electric field".
Explanation:
The nectar are agent that are secreted for pollination, specifically cross-pollination. Bees land into or nearer to the flower. Once they landed they use their proboscis for identifying the nectar or to pick it up. Bees also receive a buzz from the flower's electric field. After sensing that electric field, bees can now identify whether the visit to the flower will be worth or not. As we already know, that bee buzz across the flower is the quest for nectar.
They are found in the center of the osteon within a long opening called the Haversian canal.
Answer:
A) 300
B) 3:1
C) 9 long yellow : 3 long green : 3 short yellow : 1 short green
Explanation:
Long stems (L_) are dominant to short stems (ll)
Yellow seeds (Y_) are dominant to green seeds (yy)
We interbred pea plants with long stems and yellow seeds (L_Y_), but they had a short green parent (llyy) that could have only produced <em>ly</em> gametes, so our plants are heterozygous <em>LlYy</em>.
C) We interbred them LlYy x LlYy. If the two genes are unlinked, this is a typical dihybrid cross and from Mendel's law of independent assortment we know that the offspring will have the following phenotypic ratios:
- 9/16 L_Y_ (Long, yellow)
- 3/16 L_yy (Long, green)
- 3/16 llY_ (short, yellow)
- 1/16 llyy (short, green)
A) 3/16 × 1600 = 300 plants will be long and green.
B)
9/16 + 3/16 = 12/16= 3/4 plants will be yellow;
3/16 + 1/16 = 4/16= 1/4 plants will be green.
The ratio will be 3 yellow : 1 green
