A) Crossing over occurs in : Meiosis I ( D )
B) DNA replication would occur : Prior to meiosis I and meiosis II ( B )
C) The embryo's development represents ; meiosis and cell differentiation ( D )
D) Some organisms reproduce aseggsually ; To rapidly produce like offspring
What is Crossing over and DNA replication
Crossing over involves the swapping of genetic materials, and it occurs in prophase I of meiosis before meiosis II the crossing over of genetic materials are over. while DNA replication is the process whereby DNA make an exact copy of itself during the process of cell division and this process occurs prior to meiosis I and meiosis II
The development of an embryo in the missing diagram represents meiosis and cell differentiation.
Hence we can conclude that the answers to your questions are as listed above.

if temperature were available from several stations in canada near the great lakes do you think 15-degree line would form a closed loop?
Yes, a 15-degree line would form a closed loop for temperature obtained from several stations in Canada near the Great lakes.
What is temperature?Temperature refers to a measure of the degree of hotness or coldness of a physical body (object). Also, temperature is typically measured by using a thermometer and its units are:
Celsius (°C)Kelvin (K)Fahrenheit (°F)What is an isotherm?An isotherm can be defined as a line that is drawn on a map to join points with the same temperature, so as to show the distribution of temperature in a geographical region on Earth's surface.
In Meteorology, a closed loop is used to show or depict where an air mass is located when drawing isotherms. Thus, a 15-degree line would form a closed loop for temperature obtained from several stations in Canada near the Great lakes.

Disadvantages:
1. Cost of installation of geothermal heat pumps are high.
2. This power plants plants are suitable to particular region and they are far from cities.
Advantage to the environment:
1. It is echo friendly and non-polluting from production to use.
2. Geothermal plants occupy a less space, no-mining or no transportation is require and thus protects the natural environment.
3. There is no wastage or by -products.
Disadvantage:
1. This power plants may trigger earthquakes.
