European frog's-bit is a free-floating plant with clustered heart-shaped leaves. Resembling small water lilies, frog's bit has white flowers with three petals and yellow centers that bloom in the summer. European Frog's-bit is native to Europe but was introduced to North America in the 1930s as an ornamental pond plant. It is one of eleven invasive aquatic species identified in Maine law as illegal to import, sell, and transport. What is a way to prevent its spread in Maine lakes and ponds?
Answer:
The correct answer is - D) Educational outreach and watercraft inspections at boat ramps to keep infestation from migrating from one water body to another.
Explanation:
I just did the USA Test Prep and this is the correct answer! Hope this is helpful!!! Please up vote to help others!
The main reason for the spread of European frog's bit in Maine lakes and ponds is by boats and wildlife.
What do you mean by Invasive Species?Invasive species may be defined as species that cause ecological or economic harm in a new environment where it is not native.
Invasive species are prevented to spread in order to reduce their effect on ecological as well as economic points of view.
The best way to prevent the spread of European frog's bit is to spread awareness of its harm through educational outreach, banned their migration at the international level, and always remove visible mud and plants before leaving a water body.
Therefore, it is well described above.

Which atom keeps the electrons closer to it most of the time? (the one with the electrons on
chains in the picture)
Answer:
oxygen
Explanation:
Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds. Consequently the electrons in the water molecule spend slightly more time around the oxygen atomic center and less time around the hydrogen atomic centers.which pathways can a red blood cell take

Unlike ferns, angiosperms use ________ to contain their embryos.
spores
sporangium
pollen
seeds
answer is seeds
when you hear angiosperms think fruit
Angiosperms reproduce using seeds. Therefore, option (D) is the correct answer.
What type of seeds do angiosperms have ?Angiosperms are plants that blossom and produce fruits that contain their seeds. With around 300,000 species, they are the most numerous and diverse group within the kingdom Plantae. Approximately 80% of all known extant green plants are angiosperms.
Varied plants are angiosperms. They have leaves, stems, and roots. Angiosperm seeds are found in a flower, as opposed to gymnosperm seeds found in conifers and cycads. Angiosperm ovaries, which are typically found in flowers, are where fertilized angiosperm eggs turn into seeds.

Which of the following is a reactant during cellular respiration?
Carbon dioxide
Glucose
Energy
Water
Answer:
Glucose
Explanation:
In the process of cellular respiration, glucose and oxygen combines to produce products such as carbon dioxide and water.
Reactant+ Reactant= Product.
Glucose (Reactant)+ Oxygen (Reactant)= Carbon Dioxide (Product) and Water (Product) (C02)
Hope this helps!
The one that is a reactant during cellular respiration is Glucose. The correct option is B.
What is cellular respiration?Cellular respiration is a process of breakdown of food material to produce energy that is then saved in the form of ATP. The process occurs when oxygen is combined with food and produces energy and reduces the waste material removed from the body.
The chemical process includes four processes that occur in sequence to carry out the whole process. The processes are glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
All food that we eat gives us different macromolecules, glucose is the main source of energy. So glucose is converted into energy.
Thus, the correct option is B. Glucose.

What would happen to a plant if the chloroplasts in its cells became damaged?
Answer:
The plant would die.
Explanation:
The plant's chloroplasts are the organelles that do photosynthesis. They provide sugar (food/energy) for the plant. Without this food, the plant can't carry out other functions like growing and reproducing. Just like any other organism, the plant will die once it runs out of energy.

Explanation:
because they chemically decompose
It is true that inorganic compounds include carbon dioxide, oxygen, water, and most ionic compounds.
What are inorganic compounds?Any substance in which two or more chemical elements usually other than carbon are combined, almost always in definite proportions, is an inorganic compound.
When carbon is bound to hydrogen, the compound is classified as organic.
Organic compounds are distinguished by the presence of carbon atoms. Most inorganic compounds do not contain carbon atoms.
Water, sodium chloride (salt), sodium bicarbonate (baking soda), calcium carbonate (dietary calcium source), and muriatic acid are examples of common inorganic compounds (industrial-grade hydrochloric acid).
Inorganic compounds are characterized by high melting points and varying degrees of electrical conductivity.
Thus, the given statement is true.

essay on atoms molecules and matter
Answer:
Atoms are typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the center of the system. The electrons orbit this nucleus, like planets. If atoms are impossibly small, these subatomic particles are even more so.
Molecules are groups of atoms clumped together by chemical bonds. They are also distinguished from ions by their lack of electrical charge.
H20 is a molecule, N2 is a molecule even O3 is a molecule.

An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone.
True
False
Answer:
The answer is true.. it is attached to the carbon backbone.
The statement "An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone" is definitely true.
What is Unsaturated fat?Unsaturated fat may be defined as a kind of fat carrying a high proportion of fatty acid molecules with at least one double bond. This type of fatty acid is considered to be healthier in the diet than saturated fat.
An unsaturated fat generally contains almost all of the hydrogen atoms which are directly attached to the carbon backbone in a series of systematic arrangements.
Unsaturated fat is typically fatty acid that remains liquid at room temperature and comes from a plant, such as olive, peanut, corn, cottonseed, etc.
Therefore, the statement "An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone" is definitely true.
