Explain why the accidental and intentional introduction of new pests is likely to be an ongoing problem for future agriculture, and include possible approaches to solving the problem.
The introduction of pests in a new geographic region may have devastating consequences on crop yields. Invasive pest species often don't have natural predators or exhibit higher adaptive fitness.
Invasive species represent an important subject of concern in agriculture because they have the potential to drastically reduce crop yields.
Generally, invasive pest species don't have natural predators or exhibit higher adaptive fitness compared to well-established natural pest species.
In consequence, these species (invasive species) may cause considerable harm to crops.

Which codon is the code for the amino acid valine (Val)?
Answer: A. GUC
Explanation:
Looking at the codon chart, we see that on the lower left corner (where first base in codon is G) the whole section matches to amino acid valine. Therefore, GUU, GUC, GUA, and GUG are all correct answers, but since GUC is the only correct choice in the four choices given, GUC is the answer to this question.
Why does a cis fatty acid have a kinked shape?
Answer:
Steric hindrance in the cis orientation causes the chain to take on a more bent shape. Most natural unsaturated fatty acids are in the cis conformation. As can be seen in Figure 2.327, the cis fatty acids have a more of kinked shape, which means they do not pack together as well as the saturated or trans fatty acids

Path-breaking medical procedures have begun to pay attention to how microscopic entities aid or hinder bodily health. For example, fecal transplants have helped cure chronic digestive ailments of people who have suffered for years. These new procedures treat the body not as a separate, contained biological entity but as a complex: ___________
a. biomedicine.
b. anthrobiotic environment.
c. personal biosystem.
d. human microbiome.
Human microbiome that is as complex entity of all the microorganism found in the entire body structure of all living organism and the exact location where they are found.
Fecal transplants is idea for replenishing of good bacteria in the body due to resistance from prolong use of antibiotics. It is specifically for treatment of resistance of antibiotic therapy due C. difficile colitis.
In patient above 65, infected with C. difficile colitis and with resistance to antibiotic especially oral vancomycin, fecal transplant is applied to effectively cure this.
The transplant is conducted through the Colonoscopy. Where the fecal is discharge into the colon as the Colonoscope is withdrawal from the colon
.
Since natural good bacteria are present in fecal and have no effect on the good bacteria in the body, this procedure increased the total number of bacterial(microbiota),by stabilizing the the microbiome and curing the patients.

This unit is divided into 3 Arcs. Arc 1 answers the essential question, “What is weather and what factors influence
the weather?” The learning activities included in this arc guide students to use observation skills in order to
describe, explain, and predict weather patterns. Students will learn that the sun’s energy is the driving force of our
weather. They will complete activities to learn about wind, clouds, precipitation, temperature, and the role the
water cycle plays in our weather.
In Arc 2, students examine the essential question, “How does the ocean affect our weather?” Students will
complete activities to help them describe and explain the gulf stream, El Nino, La Nina, Sea and Land Breezes as
well as hurricanes.
Arc 3 allows students to investigate the essential question, “How does weather affect our lives?” Students will
complete activities to help them explain why our choices are based on the weather, as well as the impact that
climate change as on ecosystems. During the culminating activity in Arc 3, students research how to prepare for
extreme weather. Students have several opportunities to use their observations skills while working on their
nature journal
Explanation:
Weathering is the process by which rocks disintegrate into smaller fragments. Rock expands (with heat) and contracts (with cold) in response to temperature changes.
What is Weathering?Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms.
Rock responds to temperature fluctuations by expanding with heat and contracting with cold. This is frequently observed with a weathering process known as Frost wedging, in which water freezes and thaws inside rock fissures. Salt wedging is a different type of weathering in which the salt that is left over after water evaporates can exert pressure on rock fissures.
Thus, Weathering is defined as the process by which rocks disintegrate into smaller fragments.

Carbon is found in different forms on the Earth. It is found as carbon dioxide in the atmosphere, as carbonate and bicarbonate salts in various minerals, as well as it occurs in the elemental form of diamonds and graphite. All biotic factors are based on carbon-containing molecules like carbohydrates, proteins, fats, nucleic acids and vitamins. Carbon is incorporated into life-forms through photosynthesis which is performed in the presence of sunlight by all life-forms that contain chlorophyll. Photosynthesis converts CO2 from the atmosphere or dissolved in water into glucose molecules. These molecules are either converted into other substances or used to provide energy for the synthesis of other biologically important molecules.
The use of glucose to provide energy to living things involved the process of respiration in which oxygen may or may not be used to convert glucose back into CO2. This CO2 goes back into the atmosphere again. The process of combustion also adds to the level of carbon dioxide in the atmosphere. This percentage is said to have increased when human beings started cutting down trees, burning fossil fuels, etc. on a very large scale. Thus, carbon is cycled repeatedly through different forms by the various physical and biological activities and this cycle is therefore called carbon cycle.

Carbon cycle is a biogeochemical cycle in which the carbon atom continously moves in the atmosphere through different forms and processes.
What is Carbon cycle?The carbon cycle is the biogeochemical cycle which describes the process through which carbon atoms continually travel from the atmosphere to back to the Earth and then back into the atmosphere. This cycle goes on repeatedly. Since our planet and its atmosphere forms a closed environment, the amount of carbon in this system does not change, it only transforms from one form to another.
The processes which takes place in carbon cycle include photosynthesis, decomposition, respiration, and combustion. Carbon cycles from the atmosphere into the plants and living things. For example, carbon is a pollutant in the atmosphere which is present as carbon dioxide gas.
Carbon moves from the plants and animals to soil. When the plants and animals die, their bodies, wood, and leaves decays which being carbon into the ground. Some of this carbon is buried and become fossil fuels in millions of years. Carbon moves from living things to the atmosphere through respiration in which they inhale oxygen gas and exhale carbon dioxide gas.

Which statement is true about the energy level of solids?
A.) Solids have more energy than water
B.) Solids have more energy than plasma
C.) Solids have the most amount of energy
D.) Solids have the least amount of energy
Answer:
The answer is D.) Solids have the least amount of energy
Explanation:
Because in a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid have very low kinetic energy.
