Based on the benefits received from the Three Gorges Dam, China is planning four new dams for the Yangtze River further upstream. The new dams will provide nearly double the electricity generated at Three Gorges , and would trap sediments before they reach the Three Gorges Dam reservoir . Now that the environmental consequences of large dams are known , do you think that China should reconsider additional large hydroelectric projects ?
Answer:
No. China is already consuming third of the world's coal production for electricity, which is a serious challenge to the environmental. The trade off is fair so China should build the new dam.
No, you do not have to think that China should reconsider additional large hydroelectric projects. This is because of the fair trade-off in China that makes a difference.
What is a Hydroelectric project?A hydroelectric project may be defined as a type of renewable source of energy that significantly generates power through utilizing a dam or diversion structure in order to alter the natural flow of a river or other body of water.
Being the world's third largest producer of coal and electricity, China is creating a major threat to the environment that become one of the most potent reasons for climate change. But due to the existence of a fair trade-off in China, they are focussing on building a new and large number of dams to a larger extent.

What are two ways animals contribute to the carbon cycle?
Final answer:
Animals contribute to the carbon cycle by exhaling carbon dioxide during respiration and via methane production in animal husbandry practices, both of which affect atmospheric carbon levels and can contribute to global warming.
Explanation:
Animals contribute to the carbon cycle in several significant ways. Firstly, they participate by releasing carbon dioxide (CO2) into the atmosphere as a byproduct of cellular respiration. When animals breathe, they take in oxygen and release CO2, which is a critical component of the global carbon cycle. Secondly, through the practice of animal husbandry, humans rear large numbers of livestock for food, which further contributes to the carbon cycle. These animals not only respire, releasing CO2 but also produce methane (CH4), a potent greenhouse gas, through enteric fermentation. Hence, animals influence both the natural carbon exchange in ecosystems and the anthropogenic impacts on the carbon cycle that can contribute to global warming.

A Planet Earth
B A coral reef
C A school
D The human heart
Planet Earth is most like a closed system that does not allow transfers in or out of the system
Answer: A. Planet Earth
Explanation:
In a closed system, there is no exchange of mass. However, the energy might get exchanged. The exchange of mass and energy depends upon the property of the membrane or the boundary of the substance or an object.
The Earth is basically a closed framework; it acquires huge amount of energy from the Sun yet the exchange of matter with the outside is just about zero. Material streams between stores or sinks along pathways, or motions.

During mantle convection, heat from the earth's core causes material in the mantle to expand and move upward. When it reaches the top, it __
Answer:
Cools, moves to the side, and sinks, making a circular pattern.
Explanation:
It cools because it dissipates some of this heat to the lower crust. As it moves to the side, it drags along the crust hence powering the tectonic movements. As it cools, the liquid rock becomes denser and begins to sink to the bottom of the mantle as more hot and less dense liquid rock from the bottom rises. This forms a circular convection loop similar to that of water in a container being heated from below.
Answer:
cools, moves to the side, and sinks, making a circular pattern

Answer:
The main reason behind Plymouth settlement is to achieve freedom of religion.
Explanation:
Some of the members of Separatist Church from England in 1620, September, during the era of King James I sailed towards Mayflower and ultimately landed in the Cape-Cod or Massachusetts. They finally decided to settle in the Plymouth Rock, the first permanent European settlement in New England, The Plymouth Colony.
The Separatist believed that the European Churches have somehow failed to perform the important works of Protestant Reformation, thus they left the Church and settled in Plymouth to regain freedom of religion and securing a better Utopian society there.

Genetic engineering often involves inserting the DNA of one organism into another to create GMOs. This uses recombinant DNA technology for purposes like agricultural improvements. Examples include Roundup-ready soybeans and borer-resistant corn.
Explanation:Scientists use the process of genetic engineering primarily to insert the DNA of one organism into another organism. This is achieved using recombinant DNA technology, where foreign DNA is added in the form of recombinant DNA vectors generated by molecular cloning. The organism that receives this recombinant DNA becomes a genetically modified organism (GMO). When the inserted DNA comes from a different species, the resulting organism is referred to as transgenic.
This practice has been applied to bacteria, plants, and animals since the early 1970s for various purposes including academic research, medical treatments, agricultural improvements, and industrial applications. A famous example of GMOs in the United States are Roundup-ready soybeans and borer-resistant corn, which are common in many processed foods.

Objective means that they are "facts", and do not include personal thoughts and beliefs (which is subjective).
In this case, your answers are:
1) Fact:
Facts are made based on data and analysis, and are supported by details and other known "facts" or truths. This means that they are right in any circumstances in most cases, or at least in the given circumstance that is provided.
2) Data:
Data is used to support the fact, which is objective. Without data, the claim would be seen as a opinion, or subjective, in meaning, a "I feel that it is this way". Without data, you will not have facts.
It is not:
3) Opinion:
Opinion is the antonym of Fact, and so if Fact is a answer choice, then Opinion is not. Opinion is based off of feelings, personal knowledge, and personal preferences. While useful in some cases, it is not objective.
4) Theory:
A theory is not objective, because it is a opinion that is provable (but is yet to be proven). This makes it subjective, until proven right.

hair cell divide how many times in a year
Answer:
Hair cells are present inside the inner ear that acts as a receptor of sound. Researchers affirmed that once there is a damage to the hair cell, it can regenerate in birds.
Damage hair cell can lead to loud noise which in turn affect the ear. The supporting cells are present along with the hair cells. When the hair cells get damaged, the supporting hair cell gets the signal to start the process of regeneration.
Hair cells divide rapidly during the anagen phase, which lasts between 2 to 7 years and is marked by the active growth of hair. The hair growth cycle includes a transition phase (catagen) and a resting phase (telogen) before restarting. The growth rate during anagen is on average 0.3 mm per day.
Explanation:The number of times hair cells divide in a year varies, as hair growth occurs in three distinct phases: the anagen phase, which can last from 2 to 7 years and involves rapid cell division at the hair root; the catagen phase, a brief 2-3 week period that transitions from active growth; and the telogen phase, resting for 2-4 months without new growth. At the end of the telogen phase, a new anagen phase begins, during which basal cells in the hair matrix produce a new follicle and push out the old hair. This cycle repeats throughout a person's life, and hair typically grows at an average rate of 0.3 mm per day during the anagen phase.

A. combined with neutrons in the nucleus.
B. located in a solid sphere covering the
nucleus.
C. orbiting the nucleus in fixed paths.
D. found in regions called orbitals.
o nobis
The answer is D. The first two answers would relate to neutrons and protons and the third answer is false due to electrons never found in a fixated path.
Answer:
D. found in regions called orbitals
Explanation:
Orbitals are regions in the electrosphere of the atom where the probability of finding the electron, or the wave function that describes the motion of an electron, is greatest.
According to Pauli's Exclusion Principle, each electron has a maximum of two electrons. For orbitals that do not have both electrons, we say they are incomplete and that they are isolated or unpaired electrons.
In addition, when filling orbitals, ie, doing electronic distribution, this should be done according to the Hund Rule or Maximum Multiplicity Rule, which says that this filling should be done in a way that gets as many as possible. of unpaired orbitals.
