Which best describes a neutralization reaction? areaction between an acid and a base Oareaction between two acids O a reaction between a base and a salt Oa reaction between two salts
The statement best describes a neutralization reaction is a reaction between an acid and a base. The correct option is a.
What is neutralization?Neutralization is the reaction that occurs when acids and bases of equal strength react to generate salt and water. Because acid and bases cancel each other out, the salt generated in the reaction is neutral.
Neutralization is the reaction of an acid and a base that causes the pH to rise to 7. It is a useful process that occurs in everyday life, such as the treatment of acid indigestion and the addition of lime to acidic soil. Neutralization lowers the pH of alkali to around seven.
Taking a base helps to neutralize excess acid in our stomach. Because formic acid is present in the ant sting, it can be painful. Using moist baking soda, which is basic in nature, we can neutralize the acid action and reduce the discomfort caused by the sting.
Therefore, the correct option is a, action between an acid and a base.

Which statement best accounts for the decline in bighorn sheep populations? 1. Predators of the sheep decreased in number. 2. Sheep ewes that have shorter, spiked horns increased in number. 3. Human activities directly and indirectly affected the sheep. 4. The sheep were listed as a "species of concern" by Glacier National Park.
Answer:
The statement which best accounts for the decline of the bighorn sheep population is - " Human activities directly and indirectly affected the sheep."
Explanation: Explaination of the following statements -
Predators of the sheep decreased in number.Predation is rarely considered a major mortality factor (Wishart 1975, 1978). It is well known that bighorn sheep are preyed upon, but there is little information available on the effect(s) of predation on the populations of bighorn sheep. Numerous citations document the stalking and/or killing of bighorn sheep by a number of predators.
Thus , this statement is not correct.
Sheep ewes that have shorter, spiked horns increased in number -The larger, wild relative of the domesticated sheep is the bighorn sheep. Males are called "rams" and have long spiral horns, while females are called "ewes" with shorter, spike-like horns. With white areas on the muzzle, the back of the legs and around the rump, the coat is short, coarse and usually brown. The sheep will shed its hair once a year to reveal a new coat underneath.Thus , the statement does not match with the decline of the bighorn sheep.
Human activities directly and indirectly affected the sheep. -: Disease transmission, human interference, overgrazing, and loss of habitat are often cited as factors responsible for decreases in the abundance and distribution of bighorn sheep. these all factors comes under the human activities which directly /indirectly results in the declination of the bighorn sheep.Hence, this statement is correct .
The sheep were listed as a "species of concern" by Glacier National Park.Home to 400 to 600 bighorn sheep, Glacier National Park lists the animal as a "species of concern," that is, at risk of being endangered. The research has also shown just how sheep-like bighorns could be. They're creatures of habit, that is. Therefore , the national park indicated the species at risk , but were not responsible for their declination.
Hence, this statement is incorrect.
Therefore , the correct answer is 3 ( Human activities directly and indirectly affected the sheep.)

(Environmental) Southern England What are the major concerns about soil erosion on arable land in Britain?
Answer:
Soil nutrient loss
Algae blooms
Pollution of water ways
Explanation:
Soil nutrient loss - a major concern as when soil erodes, this results in nutrient run off. Heavy rains can "wash away" essential nutrients within the soil therefore reducing the fertility of the land.
Algae blooms - when nutrients run off soil as a result of soil erosion they can leech into nearby fresh stream and even into salt water marine environments. This large increase of nutrients results in algae thriving and forming a layer across the top of the water. This reduces the oxygen and sunlight available to other marine plants and essentially suffocates plant and animal species.
Pollution of water ways - The sediment of soil that is eroded makes its way into fresh water ways can not only "bury" plant species and reduce biodiversity but it also reduces the water quality. It can introduce pathogens to the water from liverstock farming as well as introducing pesticides that may be harmful to wildlife.

a)what are the difference between two species of minnows?
Animals are often individually consistent in their behavior, not only over time, but also across different functional contexts. Recent research has focused on phenotypic and evolutionary mechanisms explaining such personality differences through selection. Parasitism and predation induce important mortality and fitness costs, and are thus main candidates to create and maintain personality differences in the wild. Here, we present data on the behavioral consistency of the Eurasian minnow (Phoxinus phoxinus) from two populations that live in different tributaries of the same river, but whose ecological environment differs fundamentally with regard to predation and parasitism. We experimentally demonstrate that individual minnow in both study populations are consistent in their boldness and activity. However, the two study populations differ notably: in the high predation and parasitism risk population fish show higher mean boldness, but tend to be less active than fish in low predation and parasitism risk population. Parasite (Diplostomum phoxini) load was negatively, but not statistically significantly, associated with fish activity level. Our study suggests that parasitism and predation are likely important agents in the ecology and evolution of animal personalities.

Mrs. Gupta is the Cub Scout den mother. She is taking a troop of boys on a camp out and believes it will be easier if she schedules the outing to happen during the full moon. Last night she observed a third quarter moon. Approximately how many days will she have to wait before the full moon? 7 14 21 28
Answer:
The correct option is 21
Explanation:
First of all, it should be noted that the full moon is usually observed in the middle of the lunar month, which is usually 29 or 30 days, hence the full moon can be observed either on the 13th but most likely on the 14th and/or the 15th of the lunar month.
At the early days of the month, the new moon begins to form a crescent which appears and continues to get fuller (called waxing crescent) as the day goes by until half of the moon is noticed (usually after about seven days) on one side, this is known as the first quarter.
After half of the moon is noticed on one side, the moon continues to get fuller (called gibbous moon) until a full moon is noticed on the 14th/15th day. This full moon then starts waning or becoming smaller until the other half of the moon becomes visible while the initially seen half becomes invisible/clouded (this is called third quarter). This happens after another 7 days or on the 21st day. This half moon continues to get smaller (forming a waning crescent) until no moon is seen at the end of the month (around the 28 or 29th day) which is referred to the new moon.
Hence, we can see from the above that from the third quarter to a new full moon will go through the steps below
third quarter ⇒ new moon ⇒ first quarter ⇒ full moon
If each step takes about 7 days and there are 3 steps, the approximate number of days she has to wait before the full moon is 21 days.

Which of the following statements about symbiotic relationships is true?
In mutualism, neither organism benefits.
At least one organism benefits from commensalism.
In parasitism, both organisms are harmed.
Both organisms benefit from commensalism.
Answer:
At least one organism benefits from commensalism.
Explanation:
The symbiotic relationship of commensalism is when one organism benefits and the other organism receives neither benefit nor harm.
So, this statement is true, because at least one organism has to benefit from the relationship, while the other will not be harmed or helped.
