Answer:
The phosphorus in all biological tissues can be traced back to phosphorus weathered from rock.
Answer:
The correct answer is "the temperature is above 23 °C but not exceeding 40 °C".
Explanation:
The main function of virgin queens in a bee's hive is reproduction. Normally virgin queens do not exit the hive except to perform mating flight(s), which normally are done with 10–20 drone bees and then return to the hive as mated queen bees. Usually virgin queens perform her mating flight(s) in ideal temperature conditions, which are with a temperature above 23 °C but not exceeding 40 °C.
Hypothesis: If Plant Food X is used on a tomato plant, then production rate will increase.
experiment: Gather 2 tomato plants of the same height and age. Make two groups, a control group (a tomato plant without use of fertilizer) and an experimental group (a tomato plant with using Plant Food X).
For one week, give each plant the same amount of water, humidity, sunlight, and air temperature. after a week measure the height and number of tomatoes produced. gather the info in a table and compare to hypothesis after one week.
Answer:
Explanation:
<em>The probability of producing plants with white axial flowers would be 1/16.</em>
From the illustration, All F1 individuals had red, axial flowers. It thus means that red and axial genes are dominant over white and terminal genes in the pea plant.
Let us assume that the allele for flower color is A (red) and a (white); and the allele for flower location is B (axial) and b (terminal).
Pure-breeding red, axial flower = AABB
Pure breeding white, terminal flower = aabb
AABB x aabb
F1 genotype = AaBb - all red and axial
At F2:
AaBb x AaBb
Progeny
<em>9 A_B_ red/axial</em>
<em>3 A_bb red/terminal</em>
<em>3 aaB_ white/axial</em>
<em>1 aabb - white/terminal</em>
Hence, the probability of producing plants with white axial flowers in the F2 generation is 1/16.
Where is the options ???!!!
