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
Answer: Carbonic acid
Explanation:
The process of respiration of the terrestrial organism and marine organism leads to the exchange of gases. Due to exchange of gases, there is an entrance of carbon dioxide into the ocean and oxygen out of the ocean.
The addition of carbon dioxide into the water causes acidification of water and oxygen is diffused out of the water.
Hence, the product formed at Point A is carbonic acid.
The magnitude, or extent of the force applied to an object at rest or in motion will determine the rate of the acceleration for that object.
Answer: Hormones in the plant help fruits develop and ripen
Explanation:
Delayed phase preference.
Its when teenagers begin to stay up later on average about 2 hours later. It is initially caused by melatonin; its a chemical that makes us sleepy but in teenage melatonin levels rise about 2 hours later than in pre-teens, so teenagers do not get sleepy. When combined with stimulus to stay awake tv, texting or surfing the web or whatever teenagers go to bed much later.
