Philippe wants to measure how much water his potted tomato plants lose through transpiration each day. to do this, he sets up a series of experiments to capture the water that leaves the plants. which of these experiment designs would best measure the amount of water lost through transpiration? text to speech a. enclosing the plant’s roots in plastic to collect the water transpired by the plant. b. enclosing the plant in plastic so that any water lost through transpiration could be collected. c. placing the tomato plant inside a dark corner where the rate of transpiration would be slow and easy to measure. d. placing the tomato plant outside in the full sun to maximize the rate of transpiration and make measuring transpiration easy. krista has been watching a heavy rainfall outside. after the storm, she walks out and notices that there is no water in the gravel driveway, some water in the grassy yard, and a standing puddle in the hard-packed dirt in the corner of the yard. what statement best explains krista’s observations? text to speech a. the infiltration rate of the gravel is faster than that of the grassy area, which is faster than the hard-packed dirt. b. the infiltration rate of the gravel is slower than that of the grassy area, which is slower than the hard-packed dirt. c. less precipitation fell on the gravel driveway than on the grassy area, which had less precipitation than the hard-packed dirt area. d. more precipitation fell on the gravel driveway than on the grassy area, which had more precipitation than the hard-packed dirt area. transitions from condensed water to crystallized water and back again occur often in nature. such transitions are particularly frequent in winter. below are parts of a model that illustrate this idea. which statement makes the best caption to explain the role of energy in this model? a. energy is released during both transitions. b. energy is absorbed during both transitions. c. water loses energy during crystallization and gains energy during melting. d. water gains energy during crystallization and loses energy during melting.

1. The correct answer is B.

Blatantly increasing or decreasing the rate of transpiration is not an accurate way to measure the typical amount of water that is lost through transpiration, which eliminates choices C and D. The method proposed in choice B is pretty wrong and will lead to the collection of no water.

For the second question, the correct answer is A. The prompt mentioned that the dirt area contained the most water, which automatically eliminates choices B and D. What makes choice C wrong is that the water reached the materials in equal amounts, but some of them were able to infiltrate the water faster. Hard-packed dirt will, due to its thickness, always take the longest to infiltrate water.

For the third question, we know that energy is required to melt things -- thus eliminating choices B and D. Because the energy is being used, it would have to lose some energy and not gain any back unless you're melting something. The difference between choices A and C is that HEAT is released during crystallization...only! In order for something to melt, heat/energy must be taken in. So, the correct answer is C.

i believe the correct answer is the virus gets an envelope that contains host molecules when it leaves the host cell.

explanation:

during the bidding/release stage of a virus, it encapsulates itself with part of the membrane of the host cells in this case the cells of the monkey and is the reason as to why the scientist found the genetic material of the monkey on the viral cell surface.

further explanation

to understand this answer, we have to know the cycle a virus undergoes to replicate. a virus is basically a bunch of genetic material enclosed in a capsule and lacks any machinery or organelles to ensure their survival so they must enter a host cell in order to get the environment needed to survive. some viruses enter and lyse(destroy) the host cell after they have replicated and undergo the lytic cycle while some enter and leave the cell intact after replicating and these undergo a lysogenic cycle. to enter the cell, they undergo the first process called attachment by binding to specific receptors and co-receptors on the surface of the host cell. after attaching to the cell, they start the second phase called penetration where virus enters or is engulfed whole by the host cell through a process called endocytosis. it is the same process that a cell takes up materials it needs or pathogens around it. uncoating of the virus then happens after the virus has been engulfed and is the third stage. the virus then undergoes releasing of its genetic material in the host's matrix.   the materials then enter the nucleus and undergo biosynthesis by adding themselves in strands of rna being translated and then copies of the virus are produced in addition to the host genetic material. the material/newly formed viral material then undergoes assembly inside the host cell and form a capsule around them. the virus undergoes the last release/budding stage by binding to the host membrane and pushing outwards. in doing so when they tear away from the host membrane, they pick up the genetic material from the membrane of the host cell to form their envelope.
