Answer:
Option B, Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.
Explanation:
Options for the question are
A) Apply auxin directly to the shoot tip on the side to which you want the tip to bend.
B) Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.
C) Inject compounds that block auxin receptors into the part of the stem opposite from the direction you want the stem to bend.
D) Plant the roots in two different pots, and apply auxin to the root bucket that is on the same side as the direction you want the plant to bend.
Solution
Auxin is responsible for stem elongation by inhibiting growth of lateral buds. The movement of auxin is opposite to the direction of elongation of cells. Generally, Auxin moves to the dark side which is opposite to the direction i.e the lighter side in which cell elongate . Due to this growth pattern, the stem tip gets curved towards the light.
Hence, option B is correct
The fifth week of pregnancy is considered part of the embryonic stage of prenatal development.
During this stage, the embryo continues to grow in size, the placenta and the amniotic fluid begins to form, and the mother experiences several hormonal changes as a response to the embryo's implantation into the uterus of the mother.
The embryo's cells begin forming specialized functions in a process called differentiation. The baby's heart, spinal cord, and brain begin to develop, so as his/her blood cells, kidney cells, and nerve cells. His/her external physical features also begin to form.
The embryonic stage ends at the end of the 10th or the beginning of the 11th week of pregnancy, where the developing baby is now called a fetus.
Answer:
The correct answer would be :
1 volume = 369.6
2. density = 0.9199
Explanation:
Given :
dimensions : 5.5cm - 8.0cm - 8.4cm
Mass : 340 g
Formula :
volume = side * side * side
density = mass/ volume
Solution :
volume of ice cube would be
= 5.5cm * 8.0cm * 8.4cm
= 369.6 m³
density of ice cube would be
= 340/369.6
=0.9199
Thus, the correct answer would be
1 volume = 369.6
2. density = 0.9199
It was made popular by Francis Galton, but it was first mentioned in John Locke's works

Glossopteridales are the fossils that occur on the most of the landmasses. They
are the extinct group of seed plants. The rapid appearance of this one gives us
more understanding about the Paleobiography, this is the study of animals and
plants distribution through the years.
The appearance of Glossopteridales fossils also helped scientists to study so
much about their species, that includes their seeds, leaves, branches and their
oddly shaped roots. They grew at the beginning of the Permian and started to extinct
at the end of the Permian period.</span>
