How would human activities affect the migration of animals like the Christmas crabs in Australia?
Answer:
Most of Christmas Island's adult red crabs begin their breeding migration to the sea as soon as the wet season rains have established. But we can never be sure when the wet season is going to begin!
The crabs' breeding timetable is fixed around the phases of the moon. Spawning (the dropping of their eggs into the sea) must occur before sunrise on spring tides during the last quarter of the moon, regardless of any other factor. The timing of spawning is the only certain and predictable part of the whole migration; all other stages of the migration will vary with the prevailing weather.
The crabs will start their migration if there is enough time for them to complete their downward migration, mate and develop eggs before the next suitable spawning date.
The red crab breeding migration comprises a series of separate actions on the crabs' part that follow on from one to the other in a programmed sequence. These separate actions in combination make up the breeding migration and one action will not occur unless the preceding action is accomplished. If there isn't enough time for them to be able to do all of these things before the next spawning opportunity, they will delay the start of their migration and attempt to meet the following month's spawning date.
The first action that occurs is movement of crabs to the sea. The largest mass movement of crabs takes place in this first downward migration. Males farthest inland start this movement and are progressively joined by more and more crabs (both males and females) as the movement progresses toward the sea.
When the crabs arrive at the shoreline, they dip in the sea to replenish body moisture and salts. The male and female crabs then move back on to the shore terraces where the males dig burrows for mating. Mating takes place and then the males again dip in the sea and then they will start their return migration.
The females remain behind in the mating burrows to brood their eggs. This takes a couple of weeks. A day or two before the spawning date the females emerge from the breeding burrows with ripened eggs and move to the shoreline where they again dip in the sea and then retreat to shade.
Before the turn of the high tide and just before dawn the females will again move to the waterline and around the turn of the tide they will drop their eggs into the sea. After they have jettisoned their eggs the females commence their return migration.
The next phase of the breeding migration takes place in the sea. The eggs that the females drop into the sea hatch immediately into larvae. They grow through several larval stages into tiny prawn-like animals called megalops. After about four weeks the megalops emerge from the sea and they moult into baby crabs. The baby crabs then move inland and settle at suitable localities. The successful emergence of baby crabs is unpredictable but is incredible when large numbers emerge. Some years very few, or none, emerge. After about four years growth crabs will take part in the breeding migrations and the life cycle continues.
If the rains stop or peter out, the crabs will delay the start of their migration, or, if they have started migrating, they will stop moving and stay wherever they are until the rains begin again. It is rare that substantial rains will begin early enough in the year for a spawn during the last lunar quarter in October - but it has happened! Spawning in November or December are the more usual, which means that rain must commence in the preceding month and continue.
All phases of the crabs' breeding migration involve colossal numbers of crabs and usually occur all over the island. If the rains continue, there is usually a second, and sometimes even a third, smaller, downward migration by crabs that did not join in the first migration. When this happens it is possible to see crabs on return journeys mingling with the crabs on their downward migration. It can become confusing for all concerned! We are sorry that we can not be more explicit about the timing of the start of the red crab migrations, but the weather as you know cannot be accurately predicted. The best advice we can give is to be at Christmas Island during the last quarter of the moon in either November or December for the best chance of seeing something interesting happening in the annual red crab migration. If you are able to arrive earlier and to stay longer the more parts of the migration sequence you will be able to experience.

The population of North America is relatively low. Africa has a smaller population than Europe does.
Answer:
More people live in Asia than the rest of the world combined. Oceania has the smallest population of all the continents. The population of North America is relatively low.Explanation:
According to the Pie chart, 60.5% of the world lives in Asia which is above 50%. This means that the rest of the world is smaller in terms of population than Asia.
Oceania from the chart has 0.5% of the world's population which puts them at last on the population scale of continents.
North America has the second largest population at 5.2% which means that they have a low population in relation to other continents.

And to handle those trails, the fundamental requirements are physical strength and stamina. Usually, the alleys for biking aren’t decided. It is completely dependent upon the travellers and wannabe bikers. Besides Mumbai, it is full of amazing places and routes which are excellent for road trips and the best biking tours in Maharashtra. Besides, the local residents are blessed with the lustrous and soothing roads to appreciate and admire biking. One can explore the entire city and take a glance at various tourist attractions from Gateway of India to Marine Drive, Juhu Beach, Essel world, Mani Bhavan, Siddhivinayak temple and what not? Roaming and exploring around the entire city is a task requiring a lot of energy. And without chewing nosh and nibble, no human will able to visit all the places. Food is an integral part of Maharashtra’s cultural heritage, and no visit to the state can be considered complete without sampling a variety of its specialties.

What are two different ways you could find the value of a? Explain these methods.
A right triangle is shown. An altitude is drawn from the right angle to the opposite side to form 2 line segments with lengths 9 and 16. The length of the other 2 sides are 15 and a.
Answer:
Sample Response: You could use the Pythagorean theorem, since you know the length of the hypotenuse is 9 + 16 = 25 units and the length of one leg is 15 units. To find the value of a, use the relationship that the the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. You could also use the geometric mean (leg) theorem, which states that the length of the hypotenuse is to the length of an adjacent leg as that adjacent leg length is to the length of its corresponding segment in the hypotenuse. So you could write and solve the proportion 25/a = a/6.
Explanation:
I just did it
From the triangle given, the ways to find a will be the use of a Pythagorean theorem and a geometric mean.
By using the Pythagorean theorem, one will have to add the square of the legs and find the square root. Since the hypotenuse is 9 + 16 = 25 units and the length of one leg is 15 units. Then, in order to find the value of a, one will have to use the Pythagoras theorem.
Also, one can use the geometric mean theorem. Therefore, the values given will be rewritten as 5/a = a/6. Then, the person can solve the equation.

What is soil erosion?The soil fragments are loosened or washed away during this process in valleys, oceans, rivers, streams, or far-off areas. Due to human activities like agriculture and forestry, this has gotten worse.
The process of soil eroding is ongoing and can happen slowly or rapidly. As a result, there is ongoing topsoil loss, ecological harm, soil collapse, etc. The wearing away of the top soil layer is known as soil erosion. It contributes to soil degradation. The dynamic action of erosive factors, such as water, ice (glaciers), snow, air (wind), plants, and animals (including humans), is what causes this natural process. These factors determine the agents that cause erosion, which can be classified as water erosion, glacier erosion, snow erosion, and wind erosion.
