Verdich [7]2 years ago
7 0

Answer:

Normalmente, la meiosis causa la división del material cromosómico, de manera que cada padre aporte 23 cromosomas a un embarazo. Esto resulta en un óvulo o un espermatozoide que solo tiene 23 cromosomas. Cuando se produce la fertilización, se origina el número total normal de 46 cromosomas en el feto. I hope it helps you

A group of cells is assayed for DNA content immediately following mitosis and is found to have an average of 4 picograms of DNA
damaskus [11]

Answer:

b: 8;8

Explanation:

Mitotic or meiotic cell division constitute the m phase of the cell cycle. At the end of the m phase, the new cells enter the interphase stage of the cell cycle. The interphase is further sub-divided into;

  • <em>the G_0 phase,</em>
  • <em>the G_1 phase,</em>
  • <em>the S phase; and</em>
  • <em>the G_2 phase</em>.

The G_0 phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.

Actively dividing cells enter the G_1 phase after exiting the m phase. Cell development and growth takes place. From there, the cells enter the S phase where DNA replication/synthesis takes place. The cells then enter the G_2 phase where proteins are synthesized in preparation for division or m phase.

At the S phase, the amount of DNA a cell carries is doubled but the chromosome number remains the same. For example, if a cell enters the S phase with 2 g of DNA containing 10 chromosomes, at the end of S phase, the amount of DNA would have come 4 g while the number of chromosomes will remain 10.

Hence, if the average amount of DNA in the assayed cells immediately after mitosis is 4 picograms, the amount would be 8 picograms at the end of S phase and will still remains 8 picograms at the end of G_2 phase.

The correct option is b.

Which effect does deforestation have on the carbon cycle?
eimsori [14]

Answer:

Deforestation facilitates one part of the carbon cycle, increasing the CO2 in the atmosphere. It also prevents forests from absorbing any further carbon by destroying the trees. It, therefore, inhibits this aspect of the cycle and leads to increased levels of this greenhouse gas in the atmosphere.

What is a cellular organelle? list 5 different organelles that a cell might possess, and indicate the function of each. also, sp
timurjin [86]
A cellular organelle is a structure in the cell that performs a specific function.

Nucleus - stores cell's DNA; DNA replication occurs here

Ribosome - produce protein; "factories" of the cell

Mitochondria - breaks down food for energy to be used by the cell; "powerhouse" of the cell

Vacuole - store materials such as food, water, sugar, minerals, and waste products

Endoplasmic reticulum - carry materials throughout the cell; "transport system"
