Answer:
Due to mating
Explanation:
The longer and more colorful tails evolved in peacocks in the process of natural selection in order to preserve the peacock species despite causing disadvantages for the males.
The Long and colorful tails ensured that the females got attracted for mating and subsequent reproduction to ensure they didn’t go extinct.
Some homes have stairs that are too steep or narrow for moving large pieces of furniture. In such cases, furniture may be lift ed by pulleys and moved in through upper windows. What is the efficiency of a system that uses 280 N of force to lift a 100 kg bed 6 m to an upper window? Those working the system have to pull 24 m of rope to lift the bed.
Answer:
The efficiency of the system is 89.3%
Explanation:
Efficiency of a machine is defined as the ratio of useful work done by a machine to the total work put into the machine.
Mathematically, efficiency = (work output/work input) * 100%
work output = load * load distance
where load = 100 kg * 10 m/s² = 1000 N; load distance = 6m
work output = 1000 * 6 = 6000 J
work input = effort * effort distance
where effort = 280 N, effort distance = 24 m
work input = 280 * 24 = 6720 J
Efficiency = (6000/6720) * 100%
Efficiency = 89.3%
Therefore, the efficiency of the system is 89.3%

4. What happens to water immediately after it evaporates?
5 points
A. Water vapor rises and get hot.
B. Water vapor rises until it cools and condenses
C. It adds salt to the ocean and water.
D. Water vapor disappears.
Answer:
B. Water vapour rises until it cools and condenses
Explanation:
Water vapour spends regarding 10 days within the air. As water vapour rises higher within the atmosphere, it begins to chill backpedal. once it's cool enough, the water vapour condenses and returns to liquid water. These water droplets eventually gather to make clouds and precipitation.
how do the functions of DNA and RNA differ?
Answer:
DNA is functional is the transmission of genetic information. It forms as a media for long-term storage. RNA is functional is the transmission of the genetic code that is necessary for the protein creation from the nucleus to the ribosome. The DNA is a double-stranded molecule that has a long chain of nucleotides.

Choose the correct statement. A. The olecranol region is distal to the carpal region. B. The plantar region is the top of the foot. C. The mental region is superior to the nasal region. D. The pollex is lateral to the 5th digit. E. The skin is deep to muscle.
Answer:
D. The pollex is lateral to the 5th digit.
Explanation:
In hand anatomy, pollex is a medical name of thumb. Though thumb is the first digit of hand but in the medical anatomical posture, the thumb is the 5th digit of the hand. So, the pollex is lateral to the 5th digit of the hand.
The olecranol region is proximal to the carpal region; bottom of the foot is known as plantar, also called sole; the mental region is inferior to the oral region ; and muscles are deep to the skin.
Hence, the correct answer is "D."

Explanation:
Explain why the size of a new moon would affect the appearance of a solar eclipse.
Answer:
A solar eclipse can occur only when new moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic. ... Therefore, the Moon's apparent size varies with its distance from the Earth, and it is this effect that leads to the difference between total and annular eclipses.

If an advertisement follows the AIDA model, at which stage would it use engaging taglines or statistics?
Many advertisements use engaging taglines, statistics, questions, and so on as part of the (first, second or fourth) stage of the AIDA model, which is (desire, attention or interest).
Answer:
The AIDA Model Hierarchy
The steps involved in an AIDA model are:
Attention: The first step in marketing or advertising is to consider how to attract the attention of consumers.
Interest: Once the consumer is aware that the product or service exists, the business must work on increasing the potential customer’s interest level.
For example, Disney boosts interest in upcoming tours by announcing stars who will be performing on the tours.
Desire: After the consumer is interested in the product or service, then the goal is to make consumers desire it, moving their mindset from “I like it” to “I want it.”
For example, if the Disney stars for the upcoming tour communicate to the target audience about how great the show is going to be, the audience is more likely to want to go.
Action: The ultimate goal is to drive the receiver of the marketing campaign to initiate action and purchase the product or service.
Therefore, the AIDA model says that Awareness leads to Interest, which leads to Desire, and finally, Action.
Let us consider ways to use the AIDA model by looking into each part of the hierarchy
Explanation:
The AIDA Model, which stands for Attention, Interest, Desire, and Action model, is an advertising effect model that identifies the stages that an individual goes through during the process of purchasing a product or service. The AIDA model is commonly used in digital marketing, sales strategies, and public relations campaigns.

What is the AIDA model?The AIDA model stands for the Attention, Interest, Desire, and Action model. It is an advertising effect model which identifies the different stages that an individual goes through during the process of purchasing a product or a service.
The ultimate goal of the AIDA model is to drive the receiver of the marketing campaign to initiate the actions and purchase the products or services as per their requirement.
Therefore, the AIDA model says that awareness leads to interest, which leads to desire, and finally, the action.

A flower has the gene for the colors red and blue. The blue gene is dominant over red. If a plant breeder crossed a red flower with a blue flower, what will the offspring phenotype be?
Answer:
Explanation:
Let blue gene be BB
Red gene be bb
Since blue gene is dominant the allele is B
while red gene that is recessive has allele b
A cross between the two individual will give,
BB × bb
!
Bb Bb Bb Bb
Genotype=Bb
Phenotype= all blue flowers
Where the offspring have blue flower and non have a red flower.

How does the size of a vacuole change from a plant to an animal cell?
Answer AND Explanation:
Plant cells have LARGE vacuole cells, since they need to store a lot of water to stay alive, grow, and keep their stems and leaves strong. They also store the water in case there is a drought, which then they would use sparingly and for some time until there is water again.
Animal cells have SMALL vacuole cells, since they don't need to store as much water as plants, and can move around to find water. If an area becomes to dry/not enough water, the animal would move to find an area with water, instead of stay in the same place, waiting for water to come back.
