Explain how seeds travel. Be sure to give examles to support your explantion psb quic
Answers
Answer:
Wind, Water, Animals, and Fire.
Explanation:
Wind moves seeds from one place to another. When the seed gets into the air, it gets pushed by wind to another place. Water moves seeds when seeds fall into water and the water moves the seed downstream, or the water evaporates. Seeds get moved by Animals when, for example, a bird eats seeds then flies to another location, and poops out the seeds. Seeds also get moved by Fire when a forest fire erupts and the seeds fall to the ground after the fire dissipates.

difference between household wastewater and industrial wastewater
Answers
Household wastewater refers to the wastewater generated from domestic activities within residential households. It includes water from various sources such as toilets, sinks, showers, baths, and kitchen appliances. Household wastewater is typically a mixture of water, organic matter, soaps, detergents, and other substances commonly found in households.
On the other hand, industrial wastewater refers to the wastewater generated by industrial processes and activities. It originates from industrial facilities, manufacturing plants, commercial establishments, and other industrial operations. Industrial wastewater can contain a wide range of pollutants depending on the specific industry, including chemicals, heavy metals, oils, solvents, and other harmful substances.
Here are some key differences between household wastewater and industrial wastewater:
Source: Household wastewater originates from residential activities, while industrial wastewater comes from industrial and commercial processes.
Composition: Household wastewater primarily consists of organic matter, human waste, and commonly used household chemicals. Industrial wastewater can contain a diverse range of pollutants depending on the industry, such as heavy metals, toxins, and industrial chemicals specific to the processes involved.
Volume and Flow Rate: Industrial wastewater generally has a higher volume and flow rate compared to household wastewater due to the larger scale of industrial operations.
Treatment Requirements: Both household and industrial wastewater require treatment before being discharged into the environment. However, the treatment processes and technologies required for industrial wastewater are often more complex and specialized, considering the presence of specific pollutants and higher volumes.
Regulatory Control: Industrial wastewater is subject to stricter regulations and permits due to its potential impact on the environment and public health. Industries are typically required to meet specific discharge limits and implement appropriate treatment measures.
Environmental Impact: Industrial wastewater has the potential to cause more severe environmental damage compared to household wastewater, given its higher concentration of pollutants and larger volumes. Industrial pollutants can contaminate water bodies, soil, and adversely affect aquatic ecosystems and public health if not properly managed.
It's important to note that the characteristics of household and industrial wastewater can vary depending on local regulations, infrastructure, and industrial practices.
Household wastewater and industrial wastewater are primarily distinguished by their origin and point of discharge: the former is of a household character, whereas the latter is released from structures where businesses conduct their operations or produce items.
Sanitary sewage is another name for domestic sewage, which transports wasted water from homes and apartments. Waste water from manufacturing or chemical activities is referred to as industrial sewage. The location of the garbage's creation is the primary distinction between home and industrial waste. The home generates domestic garbage. Industries, manufacturing techniques, and resource exploitation all result in the production of industrial waste. The only way industrial water consumption and home water use are different is in the kinds of toxins that are emitted in huge quantities.

Waterless, alcohol-based hand gels and handwashing are equally effective before food preparation.True False
Answers
False. Although alcohol-based hand sanitizers can be an effective way to clean your hands and kill germs.
They are not always equivalent to washing your hands with soap and water, especially in certain situations such as food preparation.
While alcohol-based hand sanitizers can be a convenient and effective option for disinfecting your hands when soap and water are not available, they may not be as effective as handwashing at removing certain types of bacteria, viruses, and other pathogens from your hands. For example, hand sanitizers may not be as effective at removing dirt, grime, and other organic matter that can harbor germs.
When it comes to food preparation, handwashing with soap and water is generally considered the preferred method of hand hygiene, as it can more effectively remove dirt, grease, and other contaminants from the hands that could potentially contaminate food. Additionally, hand sanitizers may not be effective at killing certain types of foodborne pathogens, such as norovirus, that can cause foodborne illness.
Therefore, it is recommended to wash your hands with soap and water before food preparation whenever possible.

Explain how the three types of survivorship curves align with different reproductive
strategies.
Answers
Answer:
There are two types of reproductive strategies: r and k
r- strategy is the type of organism that makes a lot of babies. They have limited to no parental care. They also have a high death rate, but matures rapidly. The growth curve would be exponential like X^2.
For example: Think r for RATS because even if you think you killed all the rats, there are constantly making more.
k-strategy is the type of organism that makes a single or few babies. They give a lot of attention/parent care. They mature slowly, and low death rate. The growth curve is sigmoidal. They have limited to how much species live in that environment called the carrying capacity. Carrying capacity = maximum of # of the population within an environment (food, living space, etc).

a.The mRNA of a secreted protein is localized to the ER prior to translation
b.The ribosomes associated with the ER can only translate mRNAs for secreted or membrane proteins
c.proteins that need to reach a destination other than the cytosol contain an N-terminal signal
d.After the N-terminal signal is translated a stop codon halts translation until the ER is reached
Answers
The correct answer is c. proteins that need to reach a destination other than the cytosol contain an N-terminal signal.
Protein sorting is the process by which newly synthesized proteins are directed to their appropriate cellular locations. In eukaryotic cells, proteins can be targeted to various destinations such as the endoplasmic reticulum (ER), Golgi apparatus, lysosomes, plasma membrane, or secretion outside the cell.
The statement c. proteins that need to reach a destination other than the cytosol contain an N-terminal signal is true. Many proteins contain specific targeting signals or sequences that guide them to their intended cellular locations. The N-terminal signal, also known as a signal peptide, is one such targeting signal found at the beginning (N-terminus) of a protein. It acts as a signal sequence that directs the protein to the ER, where it is further processed and sorted to its final destination.
After the N-terminal signal is translated, it interacts with a signal recognition particle (SRP) that binds to the ribosome. This interaction halts translation temporarily until the ribosome-SRP complex docks onto the ER membrane. The protein is then translocated into the ER for further processing, folding, and sorting.
In summary, the presence of an N-terminal signal is crucial for proteins that need to reach destinations other than the cytosol, and it plays a key role in directing them to the ER for subsequent protein sorting.

when a synaptic vesicle is produced from the golgi apparatus of a neuron, it is transported to the axon terminals via maps called dynein psl 250
Answers
The statement given, "when a synaptic vesicle is produced from the Golgi apparatus of a neuron, it is transported to the axon terminals via maps called dynein," is false.
Synaptic vesicles, which are responsible for carrying neurotransmitters, are indeed produced in the Golgi apparatus of a neuron. However, their transportation to the axon terminals is typically mediated by motor proteins known as kinesins, not dynein.
Kinesins are responsible for anterograde transport, meaning they move cargo away from the cell body towards the axon terminals.
Dynein, on the other hand, is involved in retrograde transport, moving cargo in the opposite direction, from the axon terminals towards the cell body.
So, the correct statement would be that synaptic vesicles are transported to the axon terminals via motor proteins called kinesins, not dynein.

Cells can move substances directly across their membranes in three general ways: simple diffusion and ________ diffusion, which do not require energy, and _______ transport which requires an input of energy.
Answers
Answer: facilitated active
Explanation:
Cells can move substances directly across their membranes in three general ways: simple diffusion and facilitated diffusion, which do not require energy, and active transport which requires an input of energy.
What is membrane transport?Membrane transport is the mechanism by which solutions and ions are passed across plasma membranes. The membrane, being composed of phospholipids, will generate a part of it that is hydrophobic, which is the part that faces the extracellular and intracellular spaces, and a hydrophilic part that faces the center of the plasma membrane. These characteristics mean that there is a certain degree of fluidity through it depending on its composition and temperature.
This then causes selectivity in it, for this reason it is necessary to form certain channels that allow the passage of compounds that cannot pass through it due to their size or electrical charge. within the types of transport we find: simple diffusion that is through phospholipids and does not require energy, facilitated diffusion that is through channels by its electrochemical gradient and does not require energy and active transport that does require energy and is through of channels.
Therefore, we can confirm that cells can move substances directly across their membranes in three general ways: simple diffusion and facilitated diffusion, which do not require energy, and active transport which requires an input of energy.

Pyruvate starts with three carbon atoms but then it is converted to acetyl CoA which has only two carbon atoms. The missing carbon atom combines with two oxygens and exits as carbon dioxide.
A glucose molecule containing 6 carbon atoms is split into two 3-carbon molecules which are called pyruvates. Pyruvate is required in order to produce acetyl CoA.
The 3-carbon pyruvate molecule which is made in glycolysis loses one carbon atom in order to produce a 2-carbon molecule which is called acetyl CoA. The carbon which gets removed takes up two oxygens from the pyruvate with it, and exits the body as carbon dioxide.
