C makes sense, but it may be wrong... apparently transpiration is how plant's make ground water evaporate and generate clouds... most common in rain forests. It seems counter intuitive, but without it the ground simply dries out due to regular evaporation and the sun...which would sap all of the moisture out of the ground.

Which action must occur for an enzyme to catalyze a chemical reaction?
A. A noncompetitive inhibitor must first bind to an active site.
B. A competitive inhibitor must first bind to an active site.
C. A substrate must bind to an allosteric site of the enzyme.
D. A substrate must bind to an active site of the enzyme.
A complex big molecule that fastens the metabolic reactions without actually participating in it is called an enzyme. They fasten the formation and breakdown of the metabolic and catabolic reactions.
The actions that are required in a chemical reaction is:
Option: D. Active site of an enzyme must be attached to a substrate.
This can be explained as:
If a non-competitive binds to the active site then the substrate would not be able to bind to the site and a chemical reaction would not occur.If in the second option a competitive bind to the active site it will block the substrate to bind on the active site of the enzyme and the complex would not be able to form.If a substrate binds to an allosteric site then it will inhibit or activate the enzyme.Therefore, the enzyme can catalyze chemical reactions when the substrate binds to the active site.

Because the dna cannot leave the nucleus to get to the ribosomes, the genes for proteins must be transcribed into ______________ that can leave the nucleus.
The DNA in cells is transcribed into messenger RNA (mRNA), which leaves the nucleus and delivers the genetic code for specific proteins to the cytoplasm for protein synthesis. This process, called transcription, allows for proteins to be efficiently and properly synthesized in the cell.
Explanation:The DNA in cells cannot leave the nucleus to get to the ribosomes directly. Instead, the genes for proteins are transcribed into messenger RNA (mRNA) that can leave the nucleus. This mRNA is a single-stranded nucleic acid that delivers a copy of the specific gene's genetic code from the nucleus to the cytoplasm, where it interacts with ribosomes and other cellular equipment to manage protein synthesis.
During the process of transcription within the cell nucleus, mRNA molecules are produced, which are then modified and sent into the cytoplasm for translation. The transcript is decoded into a protein with the help of a ribosome and tRNA molecules. This system allows for the necessary proteins to be synthesized properly and at the right time, without having to expose the actual DNA.

Why might genetically engineering a crop to be herbicide resistant result in producing weeds that are herbicide resistant?
The genetically engineered design is flawed so weeds are not affected.
The weeds that are not affected by the herbicide are able to reproduce.
Insects that are not affected by the herbicide can pollinate new species of weeds.
The weeds will become tolerant to the herbicide through repeated exposure.
Herbicide resistant weeds can emerge when genes flow from genetically engineered crops to weeds via cross-pollination, or the weeds develop resistance through repeated exposure to the herbicide.
Explanation:Genetically engineering a crop to be herbicide resistant might result in producing weeds that are herbicide resistant through a process known as gene flow. This happens when the genetically engineered crops cross-pollinate with nearby weeds. Some of the offspring of these weeds could inherit the herbicide resistance trait, making them more likely to survive and reproduce in an environment where that herbicide is being used. Over several generations, this could result in a population of weeds that are resistant to the herbicide. In other cases, weeds may become herbicide resistant through repeated exposure to the herbicide, which can lead to the evolution of herbicide resistance.

Compaction is most significant as a lithification process for sedimentary rocks composed of sand-sized particles.
a. true
b. false
Answer:
False
Explanation:
Lithification is defined as the summation of compaction and cementation. Finer materials undergo compaction due to the force exerted by the overlying sediment layers. Clay particles (diameter < 0.002mm) undergo more compaction because they are finest in terms of size whereas silt (diameter 0.002-0.06mm) and sand-size sediments (0.06-2mm) are relatively coarser..
So, compaction is relatively a more significant process for clay particles than the silt and sand-sized particles.
Hence the given statement is false.
Compaction is NOT the most significant process as a lithification process for sedimentary rocks composed of sand-sized particles.
Sedimentary rocks are as a result of compaction, lithification and cementation.
Further ExplanationRock A rock is a naturally occurring substances that is a solid mixture of one or more minerals together with organic matter.Rocks are classified based on the chemical composition, texture and the way they are formed. Sedimentary rocks Sedimentary rocks are types of rocks that are formed through accumulation of sediments at low temperatures in tectonic layers and sinks. The process involved include compaction and cementation of sediments.These sediments includes; pebbles, shells, sand and other material fragments. The sediments accumulates in layers and then harden into rocks over a period of time.Examples of sedimentary rocks include; limestone and conglomerateLithification, cementation and compaction
Lithification is the process by which sediments combine to form sedimentary rocks. Compaction involves the consolidation of sediments due to the intense pressure and weight of the overlying deposits. Compaction takes place when sediments get buried.Cementation is the process through which dissolved minerals crystallize and glue grains of sediments together.Other types of rocks Metamorphic rocksThese are types of rocks that are formed as a result of changes that occurs due to intense heat and pressure under the surface of the earth. They result from action of heat and pressure on other rocks that pre-existed.These types of rocks are characterized by shiny crystals, ribbon-like layers among other features.Examples of metamorphic rocks are marble and gneissIgneous rocks These are types of rocks that are formed as a result hardening and cooling of magma from volcanic eruptions. Magma may cool inside the earth or when on the surface of the earth as a result of volcanic eruptions. The lava from this eruptions cools and hardens to form metamorphic rocks.Igneous rocks are glass-like and shiny with no crystals. They may also have tiny spaces and holes due to gas bubbles trapped during the cooling process.Examples of igneous rocks include obsidian and basalt.Key words: Rocks, lithification, cementation and compaction, sedimentary rocks, examples of sedimentary rocks, other types of rocks.

What are the steps (in the correct order) that link a change in the base sequence of a gene to a change in the phenotype of an organism like a mouse or a human? see section 16.2 (page 339) ?
The answer is DNA to RNA to protein. The change in DNA sequence will be reflected (through complementary base pairing) on the formed Messenger RNA during transcription. Subsequently, during translation of the mRNA to protein (by ribosomes), the amino acid sequence will change due to changes in the codons. Proteins, as you may know, are what determines the phenotype of organisms while DNA determines the genotype of the same organism.
A horse does 860 J of work in 420 seconds while pulling a wagon. What is the power output of the horse? Round your answer to the nearest whole number.
The power output of the horse is
W.
Answer:
Power output, P = 2 watts
Explanation:
It is given that,
Work done by a horse, W = 860 J
Time taken, t = 420 seconds
We need to find the power output of the horse. Power output is given by work done divided by total time taken i.e.
[tex]P=\dfrac{W}{t}[/tex]
[tex]P=\dfrac{860\ J}{420\ s}[/tex]
P = 2.04 watts
or
P = 2 watts
So, the power output of the horse is 2 watts. Hence, this is the required solution.
