Answer:

Tropical rain forests grow around the equator in South America, Africa, and Southeast Asia,  The temperature is stable year-round, around 27°C (60° Fahrenheit). As you can tell from the name, it rains a lot in these forests. Most tropical forests receive at least 200 cm (80 inches) of rain in a year. Tropical forests generally have a rainy and dry season. Temperate forests occur in the next latitude ring, in North America, northeastern Asia, and Europe, temperature ranges from -30 to 30°C (-22 to 86 F) and the forests receive 75-150 cm (30-60 in) of precipitation per year,

Answer:

Life on Earth began more than 3 billion years ago, evolving from the most basic of microbes into a dazzling array of complexity over time. But how did the first organisms on the only known home to life in the universe develop from the primordial soup?  One theory involved a "shocking" start. Another idea is utterly chilling. And one theory is out of this world!  Inside you'll learn just how mysterious this all is, as we reveal the different scientific theories on the origins of life on Earth.Electric sparks can generate amino acids and sugars from an atmosphere loaded with water, methane, ammonia and hydrogen, as was shown in the famous Miller-Urey experiment reported in 1953, suggesting that lightning might have helped create the key building blocks of life on Earth in its early days. Over millions of years, larger and more complex molecules could form. Although research since then has revealed the early atmosphere of Earth was actually hydrogen-poor, scientists have suggested that volcanic clouds in the early atmosphere might have held methane, ammonia and hydrogen and been filled with lightning as well. The first molecules of life might have met on clay, according to an idea elaborated by organic chemist Alexander Graham Cairns-Smith at the University of Glasgow in Scotland. These surfaces might not only have concentrated these organic compounds together, but also helped organize them into patterns much like our genes do now.  The main role of DNA is to store information on how other molecules should be arranged. Genetic sequences in DNA are essentially instructions on how amino acids should be arranged in proteins. Cairns-Smith suggests that mineral crystals in clay could have arranged organic molecules into organized patterns. After a while, organic molecules took over this job and organized themselves.

Answer:

Dragonflies are important for our environment.

Explanation:

Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.

Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.

Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.

Answer:

Carbondioxide gas is responsible for global warming and climate change.

Explanation:

The climate change mostly occur due to increase in the concentration of carbondioxide gas in the atmosphere. The CFCs gases causes depletion of ozone layer in the atmosphere which is responsible for prevention of ultraviolet rays coming to the earth. The burning of fossil fuels in the vehicles and industries produces huge amount of carbondioxide gas that is released in the atmosphere that allows the sunlight to the earth but block its way after reflection which remain suspended in the lower surface causes increase in temperature which leads to global warming.

Answer:

B. It inhibits the extrinsic pathway of apoptosis

Explanation:

Apoptosis is a cellular pathway that leads to programmed cell death. Viral FLICE-inhibitory proteins (FLIPs) bind to the adaptor proteins and block the interaction between the DISC complex with the caspase-8 protease enzyme, which triggers apoptotic cell death. In consequence, cells become resistant to Fas-mediated apoptosis, a pathway initiated by the FADD protein which is known to recruit caspase-8.

Answer:

To produce a healthy offspring.

Explanation:

To make a healthy offspring is the reason that is responsible for preventing fusion of multiple sperm with one egg in sea urchins because if more sperm are fused with one egg, faulty segregation of chromosomes occurs during cell division that leads to the production of nondiploid cells due to which no further development occurs. So by avoiding such type of faults in the cell, only one sperm will fuse with egg not multiple sperms.

That is one reason that preventing the fusion of multiple sperm with one egg in sea urchins has provided a survival advantage over evolutionary time to produce healthful offspring.

To make a healthful offspring is a purpose this is liable for stopping the fusion of more than one sperm with one egg in sea urchins due to the fact if greater sperm are fused with one egg, defective segregation of chromosomes happens for the duration of the molecular department that results in the manufacturing of nondiploid cells because of which no similar improvement happens. So through averting such sort of faults withinside the molecular, best one sperm will fuse with egg now no longer more than one sperms.

The making of the reproduction is a brand new organism produced through one or greater parents.

Thus it is clearly explained above.

Have both clockwise and anticlockwise directions and warmer temperature.

Explanation:

Atlantic oceans have a circular pattern of surface currents that moves in the clockwise direction in the Northern Hemisphere and counterclockwise direction in the Southern Hemisphere while on the other hand, the temperature of the Atlantic basin is warm and having high salinity in the water. The Atlantic Ocean has about 9 degrees Celsius more warmer than the water of Pacific Ocean that leads to the warmer climate of Atlantic basins.

Answer:

A energy loss through heat

When a system transforms energy from one type to another, the system always experiences energy loss through heat. So the correct option is A.

Energy is lost when it is changed from one form to another, transported from one location to another, or transferred from one system to another. As a result, part of the energy intake gets transformed into an amorphous form of energy, such as heat, when energy is transformed into a new form.

Functionally, unless one is purposefully converting energy into heat, it is nearly hard to convert all of the energy input into the output energy (like in a heater).

The energy that enters power lines always outweighs the energy that exits at the opposite end of the power lines whenever electrical energy is transferred by power lines.

Processes are never 100% efficient because of energy losses.

As it travels, energy changes significantly and assumes a variety of forms. Every conversion it passes through results in some sort of energy "loss."

Even if this energy doesn't truly vanish, part of it changes into forms that we can't utilize or don't want to use. Therefore the correct option is A.

Answer:

The layers of the atmosphere are determined based upon air temperature, which has to do with the energy of the molecules in the air. Where does this energy originally come from?

Explanation:

The layers of the atmosphere are determined based on air temperature, the energy in the air molecules comes from the sun, which increases the temperature of the atmosphere.

There are different layers of the atmosphere. There are seven layers of atmosphere. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

The sun is the only source of energy for the atmosphere. It provides heat or thermal energy and which is acquired by different molecules and these molecules convert this energy into other forms of energy.

Thus, the energy contained in the molecules of the air is derived from the sun, which raises the temperature of the atmosphere, which in turn determines the layers of the atmosphere.
