Answers
Answer:
A. They can aid in the transportation of molecules across membranes. TRUE
B. They are used in DNA replication. FALSE
C. They can act as cell surface receptors. TRUE
D. They are totally water soluble. FALSE
E. They can be enzymes. TRUE
Explanation:
A. They can aid in the transportation of molecules across membranes: This is the case, for example, of carrier proteins incrusted in membranes and in charge of transport. Active transport proteins are responsible for active transport. These transporters easily recognize a molecule and drive it into or out of the cell, an action that requires energy to occur. Also, channel protein and many carrier proteins are in charge of passive transport, which does not require energy.
C. They can act as cell surface receptors. Many proteins incrusted in cellular membranes act as receptors. A certain molecule binds to its receptor which is a protein structure that triggers an answer in the cell. As an example, we might mention neuronal communication through neurotransmitter (acetylcholine) that binds to its receptor in the postsynaptic membrane.
E. They can be enzymes. Enzymes are proteins, but not all proteins are enzymes. Some of the membrane proteins might be peripheral or integral enzymes, and their function is to catalyze reactions that must occur on the cell membrane.

Answer:
Explanation:
vPoint Source - a source of water discharged to surface water through a discrete point - generally through a pipe, ditch, or channel.
Nonpoint Source - Nonpoint sources, such as parking lots or athletic fields, discharge runoff water to groundwater or surface water; runoff does not come from a pipe, ditch, or channel. These sources may contain pollutants such as pesticides, motor oil, and soaps.
Navigable Waters of the United States For the purposes of the Clean Water Act, the term "navigable waters" includes:
all waters used in commerce, including groundwater;
all interstate waters including wetlands, mudflats, and sand-flats; and
all other waters such as lakes, rivers, streams, wetlands and sloughs.
EPA policy states, "The majority of facilities in the U.S. have the potential to discharge to navigable waters." The Supreme Court decision in (2006) requires the Army Corps of Engineers and the EPA to determine whether there is a "significant nexus" between a navigable waterway and an area a spill might affect. In June of 2007, EPA and the Army Corps of Engineers released provisional interpretive guidance regarding the "significant nexus” question. According to this guidance, the agencies will assert jurisdiction over traditional navigable waters, wetlands adjacent thereto, and relatively permanent tributaries thereof. The agencies will generally not assert jurisdiction over swales and ditches that lack routine water flow. Finally, the agencies will apply the "significant nexus" requirement and make a case-by-case, fact-specific analysis on impermanent tributaries and other wetlands.
Additional executive orders were issued 2015 in 2019. Under the 2019 proposal, traditional navigable waters, tributaries to those waters, certain ditches, certain lakes and ponds, impoundments of jurisdictional waters, and wetlands adjacent to jurisdictional waters would be federally regulated. It also details what are not "waters of the United States," such as features that only contain water during or in response to rainfall (e.g., ephemeral features); groundwater; many ditches, including most roadside or farm ditches; prior converted cropland; stormwater control features; and waste treatment systems.
Could the requirement for one or more NPDES Discharge Permit apply to my campus?
If your campus discharges pollutants directly to navigable waters of the United States through a point source, you must obtain an NPDES permit or redirect the flow of the waste.
Stormwater releases from certain activities require an NPDES permit. The most common activities on college campuses requiring NPDES permits for stormwater are construction activities disturbing more than 1 acre, hazardous waste storage areas operating under the Resource Conservation and Recovery Act permit system, steam-generating power plants, and airports. See Stormwater section below.
Regulations issued by local water authorities, or Publicly Owned Treatment Works (POTWs), not NPDES permits, govern discharges into sanitary sewer systems. See Sewer Use (POTW) section below for more information about requirements for using POTWs for commercial or industrial waste disposal.
What do I have to do related to NPDES Discharge Permits?
Determine where wastewater flows from buildings and processes on your campus. Any industrial or commercial operation (e.g., ice rink melt pits, floor drains, and vehicle wash stations) that discharge into a water of the United States may require an NPDES permit. If required, you must obtain such a permit from the appropriate regulatory agency, probably your state environmental agency.
French drains, dry wells, and septic system leach fields are different from point source discharges because they do not immediately affect surface water. Some state and federal environmental agencies manage these systems under the Underground Injection Control program, part of the Safe Drinking Water Act. See Safe Drinking Water Act for more information.

What property of water allows an animal to release excess heat in hot environments?
cohesion
adhesion
evaporation
density
Answers
The property of water that allows an animal to release excess heat in hot environments is evaporation.
Water has a high heat of vaporization, which means that it takes a lot of heat energy to turn liquid water into water vapor. When an animal sweats or pant, it releases water from its body, which then evaporates and takes the heat energy with it, thus helping the animal to cool down. The process of sweating and panting is called thermoregulation.
Cohesion refers to the attraction between water molecules, which is what allows water to form droplets and surface tension.
Adhesion is the ability of a liquid, such as water, to stick to a solid surface, like a leaf or glass.
Density is the mass per unit of volume of a substance, Water is less dense in its solid form than in its liquid form which allows ice to float on water.
Evaporation is the property of water that helps animals release excess heat in hot environments. It requires energy which comes from the animal's body heat, therefore reducing its temperature.
Explanation:The property of water that allows an animal to release excess heat in hot environments is evaporation. When an animal sweats or pant, the water on its skin or respiratory surfaces evaporates, taking away some of the animal's body heat and cooling it down.
This is possible because evaporation is a process that requires energy. The energy for evaporation comes from the body heat of the animal, effectively reducing its temperature. This is how evaporation enables animals to handle hot environments.

which type of membrane transport generally requires that the transported substance dissolve in the lipid membrane?
Answers
Simple diffusion is the type of membrane transport generally requires that the transported molecule dissolved in the lipid membrane. (option B)
Simple diffusion is a type of passive transport in which molecules move across a cell membrane from the side where they are more concentrated to the side where they are less concentrated.
The lipid bilayer's structure allows small, uncharged substances like oxygen and carbon dioxide, as well as hydrophobic molecules like lipids, to pass through the cell membrane via simple diffusion. Charged atoms or molecules of any size are repelled by the hydrophobic tails in the interior of the phospholipid bilayer and thus cannot cross the cell membrane by simple diffusion.

which of the following statements is TRUE of nonmetallic metals?
a.They are not mined for their metal content.
b. They do not contain

c. They have no value.
d. They are used as energy sources.
Answers
None of the statements is true of nonmetallic metals.
Nonmetallic metals are not a recognized classification of materials. Metals are elements that have a characteristic luster, are good conductors of heat and electricity, and are generally malleable and ductile. Nonmetals, on the other hand, tend to be brittle, poor conductors of heat and electricity, and have a variety of physical properties.
It is possible that the term "nonmetallic metals" is a confusion or misnomer with the term "metallic minerals", which refers to naturally occurring inorganic compounds that contain metals in their composition. Metallic minerals are often mined for their metal content, and have many uses in industry, construction, and technology. Examples of metallic minerals include copper, iron, gold, silver, and aluminum.
Therefore, option a) is not true because metallic minerals are indeed mined for their metal content. Option b) is not true because nonmetallic metals are not a recognized classification. Option c) is not true because metallic minerals have value. Option d) is not true because nonmetallic metals do not exist.

Yes, the driver's behavior corresponds to a measured BAC of 0.12%.
If the driver had two beers, he might have been less inhibited, less judgmental, and less attentive.
Yes, the driver might show mild impairments in balance, speech, vision, reaction time, and hearing. It is not safe to drive with these effect.
What are BAC levels?Blood alcohol content, also known as blood alcohol concentration or blood alcohol concentration, is a measure of alcohol intoxication used for legal or medical purposes. It is mass of alcohol per volume or mass of blood. BAC values above 0.08% are considered endangered. Exceeding 0.4% is lethal.
A standard 12 ounce beer has about 5% alcohol. This equates to approximately 14.03 grams of alcohol per glass of beer. If the driver had two glasses of beer, he used 28.06 g or 28.06 ml.
The driver weighs around 160 lbs or he is 72.57 kg with 72,560 ml of body volume.
Most men's bodies are 68% water. Therefore, the amount of water in his body is 49,350 ml.
BAC = (28.06/49,350) × 100
= 0.0569%

Please select the best answer from the choices provided A B C D
Answers
The best answer is option C. Animals produce carbon dioxide used by plants for photosynthesis.
In the oxygen-carbon dioxide cycle, plants undergo photosynthesis, a process where they use sunlight, carbon dioxide, and water to produce glucose (food) and release oxygen as a byproduct. Animals, on the other hand, undergo respiration, where they consume oxygen and produce carbon dioxide as a waste product. The carbon dioxide produced by animals is used by plants during photosynthesis as a source of carbon. Through this process, plants recycle carbon dioxide and convert it back into oxygen, completing the oxygen-carbon dioxide cycle. Therefore, animals play a crucial role in providing carbon dioxide to plants, which is used by plants for photosynthesis. The correct answer is C. animals produce carbon dioxide used by plants for photosynthesis.

A heterozygous white rabbit is crossed with a black rabbit. What is the probability of getting black rabbit offspring?
Answers
Answer:
1/2 or 50%
Explanation:
From the illustration, we will logically assume that the white allele is dominant over the black allele. Let us also assume that the white allele is represented by A, the alternate black allele will be a.
The heterozygous white rabbit will have the genotype Aa.
The black rabbit will have the genotype aa.
Crossing the two rabbits together:
Aa x aa
Aa Aa aa aa
1/2 Aa - white color
1/2 aa - black color
Hence, the probability of getting a black rabbit offspring is 1/2 or 50%
