Compare How is the life cycle of
a mammal different from the life
cycle of an animal that undergoes
metamorphosis?
Differences between mammals and animals are:
• Animals could be either ectothermic or endothermic, but mammals are always endothermic.
• Only mammals have hairs on the skin out of all the animals.
• Only mammals have mammary glands and sweat glands out of all the animals.
• The most sophisticated heart and the circulatory system are present in mammals out of all the animals.
• Mammals have more complex living habits (e.g. human) than other animals.
• Number of mammals is only a fraction compared to the rest of the number of animals.
• Some mammals are capable of singing, but other animals are not.
A stone dropped freely from 72m height of
the tower and reaches the "ground on 6 seconds
calculate acceleration due to gravity of that stone
At what condition does the acceleration due to
gravity becomes Zero
When the initial velcity is 12 m/sec in that condition the acceleration due to gravity becomes Zero.
What is acceleration?The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.
The height from the stone drop,h= 72 m
t is the time period=6 sec
From Newton's second equation of motion;
[tex]\rm h = ut +\frac{1}{2} gt^2\\\\[/tex]
The condition does the acceleration due to gravity becomes Zero will be;
The gravitational acceleration is zero;
[tex]\rm h = ut +\frac{1}{2} \times 0t^2\\\\h=ut \\\\ 72 =6u \\\\ u= 12 m/sec[/tex]
Hence when the initial velcity is 12 m/sec in that condition the acceleration due to gravity becomes Zero.

Describe patterns you observe in Earth’s surface temperature. How do these patterns change during the course of a year and from year to year? Use lines of latitude and degrees Celsius in your description.
Answer:
In this unit, we will be discussing Latitude as a climatic control. By latitude we are not talking about geographic location. Rather our interest will center on the effect of latitudinal location on the receipt of solar energy at the Earth's surface. To a degree the Greeks were on to the idea when they proposed their Torrid, Temperate and Frigid temperature zones over 2000 years ago.
02. Specifically in this section on Latitude, we are going to cover four topics:
Earth-Sun Relationships. This section will deal with the actual receipt of solar energy at the Earth's surface. The receipt of solar energy is directly related to the relationships which exist between the Earth and the Sun across the year. All of you would recognize the basic relationships. Each day we can see that the Sun "rises" in the east and sets in the west. Most would also recognize that over a 12 month period the Sun "moves" from north to south in our sky. In other words, the Sun not only "moves" from east to west, but also north to south. And how about the fact that days tend to get longer in the northern hemisphere from December 21 to June 21, and then grow shorter from June 21 to December 21? Earth-Sun relationships cause changes in the amount of insolation received day to day and seasonally. And, depending upon the relationship, the amount of insolation changes locationally and through time. The resultant temperatures created due to these changing relationships create pressure differences which are largely responsible for winds. The winds in turn drive the ocean currents and our weather.

In 2010, the Soufriere Hills volcano on the Caribbean island of Montserrat erupted violently, spewing huge clouds of ash and gases into the sky. How do the volcanic eruptions at the end of the Permian period and the formation of Pangaea, both of which occurred about 252 million years ago, set in motion events that altered evolutionary history
Answer and Explanation:
Pangaea is the term used to describe the supercontinent that existed millions of years ago, before the continents were spread across the globe as we know it today. The separation of continents occurs due to the rapid convections of the Earth's mantle. These mantle convections increased volcanic activity on the earth, making volcanism very active and causing numerous volcanic eruptions, which increased the concentration of carbon dioxide in the atmosphere, increasing the greenhouse effect and creating a long period of intense global warming.
It was this global warming that altered the evolutionary events on earth, promoting a strong natural selection of plants and animals, which even led to the creation of new species and extinction of old species, in addition to creating a geographical and environmental modification.
La Soufriere Hills volcano is a group of active volcanoes. The volcanic eruptions altered the climatic conditions and led to natural selection.
What is Pangaea?Pangaea was used to describe the supercontinent that existed millions of years ago before the separation of the continents present now. The rapid convections in the mantle of the Earth caused the shift and drift in the tectonic plates.
The movement of the tectonic resulted in increased volcanic activities that caused numerous volcanic outbreaks resulting in increased carbon dioxide concentration in the environment.
This led to global warming and resulted in a change in climatic conditions. Global warming altered the evolution of the organisms through the process of natural selection and led to the extinction and the introduction of species.
Therefore, volcanic eruptions and Pangaea resulted in environmental and geographical alterations.

Answer:
It can change over time for certain kinds of loans. It is the interest charged each year for a loan. It can be reduced to reflect the borrower’s credit history.Explanation:
The annual percentage rate is the amount of interest that is charged to the loanee for borrowing the loan and it is different for different types of loans such that with some kinds it can change overtime based on certain factors such as inflation.
Percentage rates are a reflection of the riskiness of the borrower so if the borrower has a good credit history, the rate can be reduced to show that the borrower is not too risky.

At high elevations or high latitudes, some of the water that falls on the land does not immediately soak in (infiltrate), runoff, evaporate, or transpire. Where is this water being temporarily stored
Answer: Snowfield or Glacier
Explanation:
The higher one goes, the colder it becomes. This affects water as well when it falls to the earth. If it falls in an area that is cold such as high elevation areas, it would end up freezing up and becoming snow.
When this happens, it would usually be stored in an area with other snow such as a snowfield or a glacier. This is why high mountains usually have snow caps. Mt. Kilimanjaro for instance in is Mid-Africa, a region which gets no snow whatsoever yet, it still has a snow cap.
