People are supercharging the natural greenhouse effect, which raises the earth's temperature, if the amount of industry and auto emissions increases and more carbon dioxide is released into the atmosphere.
<h3>How do carbon emissions grow over time?</h3>
Nearly all of the 150-year rise in greenhouse gases in the atmosphere is a result of human activity. Burning fossil fuels for transportation, electricity, and heating accounts for the majority of greenhouse gas emissions caused by human activity in the United States.
<h3>How do emissions affect the environment?</h3>
They contribute to respiratory problems from smog and air pollution, and they influence the climate by trapping heat. Other consequences of climate change brought on by greenhouse gases include more wildfires, extreme weather, and interruptions in the food supply.

Answer:
It is a trait highly influenced by environmental factors (i.e., it has low heritability)
Explanation:
In population genetics, heritability is a statistical measure to estimate the proportion of the phenotype variation of a given trait which can be explained by hereditable genetic factors. The heritability of a trait is influenced by environmental factors, genetic factors (e.g., allele frequencies, number of genes involved in trait variation, recombination rate, etc), and the interaction between genetic and environmental factors. A low heritability value suggests that most of the variation is not genetic (i.e., due to environmental factors), while a high heritability value suggests that almost all of the variability in a trait is due to genetic factors.
* Channel proteins- these are proteins with a hydrophilic pore where specific ions are able to pass through the membrane. Each channel protein is specific to an ion. This is the only way ions can travel through the membrane. They are trans membrane proteins.
* Carrier proteins- these are proteins which allow larger or polar molecules through the membrane. They are trans membrane proteins.
Carrier proteins essentially “carry" signals that are not soluble in aqueous solution through the blood stream to their target cells. Carrier proteins for hydrophilic signals prevent degradation of the signal. Channel proteins are embedded in cell membranes. They often are receptors (though not always), and when activated, allow specific ions to pass through the membrane.
A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilic passageway for water and small, polar ions. Like all transport proteins, each channel protein has a size and shape which excludes all but the most specific molecules
The carrier protein facilitate diffusion of molecules across the cell membrane. The protein is imbedded in the cell membrane and covers the entire membrane. This is important because the carrier must transport the molecule in and out of the cell.
Answer:
The principal components of the plasma membrane are lipids ( phospholipids and cholesterol), proteins, and carbohydrates.
Answer:
respiratory system
Explanation:
this happens in the lungs, part of the respiratory system
