Homologous chromosomes may exchange segments; this is called crossing over. Crossing over increases genetic variability. When does crossing over occur?


Question 2 options:


Meiosis II



Mitosis



Both mitosis and meiosis--crossing over may occur at any time during the cell cycle.



Meiosis I


Question 3

In order for meiosis to create four, genetically different gametes, DNA replication must occur. Which of these best describes when DNA replication would occur?


Question 3 options:


prior to meiosis II



prior to meiosis I and meiosis II



prophase I in meiosis I



prior to meiosis I

Question 4 (1 point)
The embryo's development as seen here represents which processes in the development of any multicellular organism?


Question 4 options:

meiosis followed by mitosis.


mitosis and cell differentiation.


protein synthesis followed by meiosis.


meiosis and cell differentiation.

Question 5
Why do some organisms reproduce aseggsually?

Question 5 options:

To rapidly produce like offspring


To increase genetic diversity


To have a variety of offspring at the same time


To get rid of genetic problems while reproducing

Answers

Answer 1

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.

Advantages to community:

1. Geothermal energy is a renewable  energy resource because heat extracted is very small compared to the Earth's heat content.

2. It is reliable and constant source of energy as it can extracted all through the year despite changing weather patterns.

3. Geothermal energy is widely available and it creates new job opportunity.

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.

2. Power plant uses lot of water in its processes.
