Why would a certain trait have a
lower fitness than another causing
that trait to die off in a certain
population?
A. The trait has been around too long to be useful.
B. The trait does not benefit or hinders the
organism.
C. The trait does not wish to be passed on.
Answer: B
Explanation: Traits usually die off when they are unneeded by the organism, or if the trait causes harm to the organism's survival. Through natural selection, over time, the organisms with the best combination of traits for its survival will become the dominating species, and those with weaker traits may not survive long enough to pass off their traits to future offspring.

what are some negatives and some positives of coastal development?
Answer: Positive: Coastal areas help prevent erosion; filter pollutants; and provide food, shelter, breeding areas, and nursery grounds for a wide variety of organisms.
Negative: Added to this are impacts such as increased erosion due to coastal development, increased pollution, and increased boat traffic - all of which lead to further habitat loss and put increased pressure on marine species. ... Other coastal developments can also harm sensitive marine habitats and species.

sweat acts as a cooling agent on the body because of water high heat of vaporization or high specific heat capacity?
Explanation:
Large amounts of heat are needed to evaporate water, because H-bonds need to be broken. Sweating is an example of using water as d coolant. As the sweat evaporates it pulls heat away from the body. Application 'Water's thermal properties, its high specific heat, means that it can cool us.
Suppose you created a set of Instruments using water and drinking glasses. You need a note with a very low pitch to complete a certain song-what should you do? Pour out some of the water in the glass with the most water. Add more water to the glass with the most water. Pour out some of the water in the glass with the least water. Add more water to the glass with the least water.
Answer:
Add more water to the glass with the most water.
Explanation:
The glasses with more water have lower pitches and the glasses with less water have higher pitches. To create a lower pitch you need to add more water to the glass with the most water. If there is no room to add water, you need a larger glass!

If a person in the northern hemisphere observes a full moon, what moon phase would a person in the southern hemisphere observe on the same night? Be detailed in your explanation.
(SCIENCE)
Answer:
nooo
Explanation:
because the earth rotates changing the hemispheres
An increasing waxing moon's phase is seen from the Northern Hemisphere as it moves from right to left. Meanwhile, a waxing moon increases its phase from left to right as seen from the Southern Hemisphere.
What is Hemisphere?Hemisphere is defined as the Earth is evenly divided into two half by any circle that is drawn around it. The atmosphere is one of the fundamental elements of Earth's interrelated physical systems. The layers of gases that envelop a planet or other celestial body are its atmosphere. About 78% of the gases in the Earth's atmosphere are nitrogen, 21% are oxygen, and 1% are other gases.
In comparison to the northern hemisphere, the Moon does appear to be "upside down" in the southern hemisphere. It's only an issue of orientation here. Imagine that the equator and the Moon's orbital plane are the same.
Thus, an increasing waxing moon's phase is seen from the Northern Hemisphere as it moves from right to left. Meanwhile, a waxing moon increases its phase from left to right as seen from the Southern Hemisphere.

What primary method does the cell employ to ensure gene expression only occurs when necessary?
Limited amounts of specific DNA
Phosphorylation cascade with multiple steps
Receptors that only fit specific hormones
Unique transcription factors made of carbohydrates
Answer:
Unique transcription factors made of carbohydrates
Explanation:
Gene expression refers to the way by which the genes which contain hereditary materials in the cells are converted to certain proteins. Gene expression is regulated to avoid the wastage of useful energy. Transcription allows the copying of genetic information from the DNA to the RNA.
Transcription factors can activate or deactivate a gene thus hindering its expression. Unique transcription factors help to regulate gene expression.
Answer: receptors that only fit specific hormones

acid precipitation results when___and____ compounds react with water in the atomsphere
Answer:
Sulfur; nitrogen.
Explanation:
Acid precipitation results when sulfur and nitrogen compounds react with water in the atmosphere.
This acid precipitation is also known as acid rain and it is typically caused by the chemical reaction between sulfur oxide and nitrogen oxide which are released into the air as a result of burning fossil fuels, with water and other chemical elements present in the atmosphere.
Generally, acid precipitation (acid rain) usually have a pH of about 5.1 or below and as such, it is very acidic nature i.e possessing a large amount of hydrogen ions.
Hence, acid precipitation (acid rain) when washed to the earth has negative or harmful effects on various living and non-living organisms such as animals, plants, cars, buildings etc.
