Which option is an example of an automatic regulatory reaction?
A. sweating
B. burrowing underground
C. taking in more calories
D. wearing a jacket
Answer:
A. Sweating
Explanation:
I just took it <3
The option which is an example of an automatic regulatory reaction is: A. sweating
Automatic regulation can be defined as a biological process that occurs within many living organism due to the function of an internal adaptive mechanism that typically works to mitigate (lessen or adjust) its system's response to stimulus.
Generally, the body organs and system that are considered to carry out some degree of automatic regulation are:
The brain.The heart.The kidney.Hence, an automatic regulatory reaction is a biological process that happens in response to other bodily process and stimuli.
For instance, the nervous system produces an automatic regulatory reaction to emotions (fear), illness and heat such as sweating.
Sweating is an automatic regulatory reaction of the human body to protect and mitigate the effects of an extreme change in temperature (heat).

what makes angiosperm more advance than gymnosperm
Answer& Explanation:
Angiosperm is more advanced due to the mechanism of protection it has since developed as opposed to its predecessor, gymnosperm. Angiosperms could be deemed the inventors of animal-mediated pollination or dispersal, whereas gymnosperms mostly depend on wind-mediated pollination (which is far more of a gamble than animal mediated).
1) Angiosperms seeds are enclosed in fruits, which increases the chances of dispersal by either wind, water, or animals. Animals can eat the fruit and disperse the seeds via feces or by brushing the fruit off of their fur coats new areas of the terrain.
2)The development of flowers. Flowers are especially important because depending on the flower it can attract a set species of animals in order for pollination to occur. That species of animal could only focus on those few flowers and would allow the female part of the flower to receive pollen (produced by the male part of the flower) from all over the place. This theory is also applicable to animal mediated fruit dispersal.

You never have to worry about wastewater becoming contaminated because it can run through local treatment plants, true or false?
A person still have to be worried about wastewater becoming contaminated even though it passes through local treatment plants.
Wastewater refers to the water they has been used. It consists of the substances like human waste, oils, chemicals , food scraps etc.
Even though used water runs through local treatment plants, it should be noted that not all the solid waste are removed as some of the waste will still end up getting into nearby rivers or streams and this can result in contamination when one eventually uses such water.
In conclusion, one still has to be worried even though the wastewater runs through local treatment plants. Therefore, the correct option is False.

Im so sorry if im asking alot of questions but i dont know anything so can someone help me ?
Answer:
The homogeneous mixture is only in the one phase of matter, whereas heterogeneous mixture is always in two or more than two different phases of matter. Solutions are termed as the homogeneous mixtures, on the other hand, suspensions or colloids are termed as the heterogeneous mixtures.
Examples:
Homogeneous:
Bronze: this alloy is an example of homogeneous substances since it is composed of tin and copper.
Milk : this mixture that we see in a uniform way is composed of substances such as water and fats.
Heterogeneous:
Mixtures in two or more phases are heterogeneous mixtures. Examples include ice cubes in a drink, sand and water, and salt and oil. The liquid that is immiscible form heterogeneous mixtures. A good example is a mixture of oil and water.

The carrying capacity of an ecosystem will most likely become unbalanced when?
Answer:
In a population at its carrying capacity, there are as many organisms of that species as the habitat can support. ... If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.
Explanation:
When resources are depleted faster than they are replenished, the species has reached its carrying capacity. If this happens, the population will shrink in size.
What is carrying capacity?Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.
Carrying capacity, or the maximum number of people that an environment can support over time without destroying or degrading it, is determined by three key factors: food availability, water availability, and space.
Carrying capacity is the maximum number, density, or biomass of people that a given area can sustainably support.
This is likely to change over time and is influenced by environmental factors, resources, and the presence of predators, disease agents, and competitors.
Thus, any disturbance in these factors can lead to an unbalanced carrying capacity.

Which of these chemicals is not a pollutant?
A. Methane
B. Nitrogen gas
C. Nitrate
D. Carbon dioxide
Answer:
All these chemicals are primary causes of pollution. Although, only one isn't an air pollutant. Which would make my best Guess C. Nitrate
Explanation:
A. Methane Is the main component in gas and oil. Oil companies have been responsible for polluting our air with about seven million tons of methane per year.
B. Nitrogen gas in general is one of the main air pollutions. otherwise know as Nitrogen dioxide.
C. Nitrates are found in ground waters and transfers into the soils surrounding said waters. Nitrates commonly are a cause of death in infants when drinking tab water or eating crops grown from nitrate infected soils. Adults aren't nearly as infected by this.
D. Carbon Dioxide is a greenhouse gas that pollutes our air and has been a main cause of global warming.
I'm at a loss for answering this question since all of these are polluting our earth in some way. The only way I can think to answer this is that all but one are air pollutants. So maybe the one that is not a air pollutant is the correct answer. My best guess is C. Nitrate

A cotransporter is something that moves two substances across a membrane, one passively and the other actively. The Na+/ K+ ATPase transports sodium and potassium ions across the plasma membrane against their concentration gradients. This pump is not considered a cotransporter because
Answer:
both ions are transported actively
Explanation:
If both ions are being transported against their concentration gradients, then they are both being transported by active transport, as it requires energy.
A co-transporter moves two substances across the membrane, one passively and one actively. But in this case neither ion is moved passively, so it cannot be considered a cotransporter
Help me please hurry???????????
Answer:
Compared to the use of many gasoline vehicles with only one person per vehicle, this method of transportation conserves more fossil fuels.
Explanation:
A form of transportation —such as the subway or streetcar— has capacity for many passengers and uses electricity as an energy source. This means fewer people using gasoline-vehicles, which leads to savings in fossil fuels, such as gasoline or diesel.
The decrease in the use of fossil fuels in vehicles has been proposed as an alternative to reduce environmental pollution and its consequences. One alternative is to consider mass transport vehicles that use alternative energy, a sustainable form of transport.
None of the other options are correct, as they involve more or the same use of fossil fuels per person.
Composites are made from
a. layers of wood glued together in sheets
b. two or more plastics mixed together to make a new plastic
c. two or more materials mixed together that chemically mix into a new material
d. two or more materials mixed together to make a stronger material but the individual components remain visible
GREETINGS!
D is the answer
Explanation:
A composite is made by combining two or more other materials so they improve one another but keep distinct and separate identities in the final product. So a composite isn't a compound (where atoms or molecules bind together chemically to make something quite different), a mixture (where one material is blended into another), or a solution.

Repeat the demonstration on a paved surface such as a driveway or sidewalk and document the differences. With no soil to absorb this water, what would happen in a heavy rainstorm? How would an engineer in charge of a city's flood control system prepare for the runoff generated on paved parking lots and roads in a heavy rainstorm?
Answer:
Explanation:
Without soil to absorb the excess water, a heavy rainstorm will cause massive flooding. The water will accumulate over the pavement and keep rising until it finds soil or a runoff since water always levels itself out. To prevent situations such as this one an engineer should implement drainage tunnels between the road and the sidewalks. This would allow the water to be drained and flow to the nearby body of water. This would easily prevent flooding during a heavy rainstorm.
Answer:The rate of absorption into the soil was very slow, which meant that some of the water flowed over it and was either absorbed in a different area, or ran onto the driveway and down into the street. It was a warm sunny day, so after a while the wet patch of water on the sidewalk had dried up (evaporation). Once the soil got wet from absorbing the water, the rate of absorption got even slower – like the soil was “full” – and more water ran over onto the driveway. The water on the driveway moved very quickly, since the concrete didn’t absorb it. Our street has never flooded before, but I have seen heavy rainstorms where the water was moving down the street like a big stream, carrying fallen leaves and trash down into the storm drains.
