What is primary succession?Succession on land that did not previously have plants, such as soil exposed as a glacier retreats or a new sand bar in a river is called primary succession.
It takes over 600 years to primary forest succession to reach the climax. it includes breakdown of the rocks into soil and plants help in survival of different animal and progress from primary succession to the climax community.
Hence, option 'D' is correct.

How would filling in
wetland to create a field affect the surrounding environment?
Answer:
The filling in a wetland can have bad effects, such as burring the wetland vegetation, increasing the elevation, and eliminating periodical inundation of the wetland.
Explanation:
Filling in a wetland can be done with various types. One of them is communal waste. Also, the construction materials are disposed of in wetland areas.
This can produce dangerous chemical elements and release toxins. Filling in the wetland can cause the loss of these areas and the fertile lands used for agriculture.

c. Ice from the North and South poles is melting and adding to the water in the ocean.
d. The waves are bigger because of increased winds.
10. Hurricanes are large storms that form over warm waters out in the ocean. Hurricanes are associated with low-pressure regions in the atmosphere. How does the low pressure associated with a hurricane help them to grow big and powerful?
a. Air in the atmosphere tends to move toward low-pressure regions, which would increase the winds surrounding a hurricane.
b. Low-pressure regions push away other air in the atmosphere, which would make the hurricane bigger.
c. Low-pressure air heats up the water and therefore makes the hurricane stronger.
d. Low-pressure conditions means slow winds, which makes the hurricane stronger.

The events taking place in two different locations are described below:
Location A: Movement of plates causes hot spots to move to a location with thinner crust
Location B: Tectonic plates move away from each other under the sea
In which location will active volcanoes most likely be formed and why?
Location A, because the magma breaks through the thin crust
Location A, because cracks between plates are filled with molten rocks which solidify
Location B, because the oceanic plate and continental plate are pushed up through the crust
Location B, because the thinner oceanic plate will be pushed under the continental plate
Answer:
Location B, because the oceanic plate and continental plate are pushed up through the crust

What are two contributing factors to evolution?
The culture you are working has a doubling time of 2 hours and a cell density of 3 x 10^6 cells per mL. For your experiment, you first dilute the culture 100 fold. Assuming that there is no lab phase and that the cells remain in exponential growth the entire time, what is the cell density (cells/mL) after 10 hours
The cell density (cells/mL) = 15× 10^6 cells per mL.
Calculation of cell densityThe doubling time of culture = 2 hours
The cell density after 2 hours = 3 x 10^6 cells per mL
Since the dilution did not affect the lag phase and exponential growth rate, the cell density after 10 hours is calculated below:
2 hour = 3 x 10^6 cells per mL
10 hours = X
Cross multiply,
[tex]x = \frac{10 \times 3 \times10 {}^{6} }{2} [/tex]
[tex]x = \frac{30 \times 10 {}^{6} }{2} [/tex]
X= 15× 10^6 cells per mL
Therefore, the cell density in (cells/mL) after 10 hours = 15× 10^6 cells per mL.

Why are all four chromatids different?
Answer:
They differ from both parents and also from each other. This occurs through a number of mechanisms, including crossing-over, the independent assortment of chromosomes during anaphase I, and random fertilization. When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur.
