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.

A. As temperatures increase, corals lose symbiotic algae, which provide most of their habitat
B. As temperatures decrease, corals lose their symbiotic algae, which provide most of their energy.
C. As temperatures increase, corals lose their symbiotic algae, which provide most of their energy.
D. As temperatures increase, corals gain symbiotic algae, which hinder their ability to conduct photosynthesis.
As temperatures increase, corals lose their symbiotic algae, which provide most of their energy. This is the best description to the effect of coral bleaching on corals. Thus, the correct option is C.
What are coral reefs?A coral reef is an underwater ecosystem which is characterized by the reef-building corals. Bleached corals are found in the underwater ecosystem which most likely show reduced growth rates, decreased reproductive capacity, increased susceptibility to diseases, and elevated mortality rates than the normal coral reefs. Changes in the coral community composition can occur when the more susceptible species are killed by bleaching events in the ecosystem.
When the conditions such as the temperature change, corals are expelled out the symbiotic algae which is living in their tissues, it is responsible for their colour. A spike of the temperature to 1 to 2°C in the oceans sustained over several weeks which can lead to bleaching, that turns corals white. If the corals are bleached for prolonged periods of time, they eventually die.
Therefore, the correct option is C.

Hope it helpfulThe 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.

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

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.
