According to the pressure flow hypothesis of phloem transport, Group of answer choices solute moves from a high concentration in the source to a lower concentration in the sink. water is actively transported into the source region of the phloem to create the turgor pressure needed. the pressure in the phloem of a root is normally greater than the pressure in the phloem of a leaf. the formation of starch from sugar in the sink increases the osmotic concentration. the combination of a high turgor pressure in the source and transpiration water loss from the sink moves solutes through phloem conduits.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
