DNA replication occurs prior to meiosis and _________.

Biology
1 answer:
Evgesh-ka [11]3 years ago
6 0
A. Mitosis is the correct answer.

DNA replication occurs in the two major types of cell division: mitosis and meiosis.

Mitosis is the splitting of a normal cell into two daughter cells and involves complete replication of the cells DNA to produce two identical copies. Meiosis is a specialised and more complex two-stage form of cellular division related to sex cells and involves DNA replication followed by an exchange of DNA material within/between the chromosomes to mix genes from both parents and produce daughter cells with half the number of chromosomes as the original parent cell. Animal sperms and eggs are examples of cells produced by meiosis and contain half the number of chromosomes as normal cells. When combined during fertilization the egg and sperm produce a cell with the full compliment of chromosomes.

Cytokinesis is a part of the cellular life cycle that is related specifically to the division of the cytoplasm (basically the "soup" of material inside the cell). It is part of the cellular division process but not specifically related to nuclear division (i.e. DNA replication).

Transcription relates to the production of RNA from DNA which is then used for protein synthesis. DNA is not replicated during the transcription process, rather, this is a separate process critical for the production of proteins by the cell.

Explain the respiratory system of a frog and the importance of "vacularization" of the skin and the mesentery
fredd [130]

 The skin is composed of thin membranous tissue that is quite permeable to water and contains a large network of blood vessels. The thin membranous skin is allows the respiratory gases to readily diffuse directly down their gradients between the blood vessels and the surroundings. When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air.

A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs. The mechanism of taking air into the lungs is however sligthly different than in humans. Frogs do not have ribs nor a diaphragm, which in humans helps serve in expand the chest and thereby decreasing the pressure in the lungs allowing outside air to flow in.

In order to draw air into its mouth the frog lowers the floor of its mouth, which causes the throat to expand. Then the nostrils open allowing air to enter the enlarged mouth. The nostrils then close and the air in the mouth is forced into the lungs by contraction of the floor of the mouth. To elimate the carbon dioxide in the lungs the floor of the mouth moves down, drawing the air out of the lungs and into the mouth. Finally the nostrils are opened and the floor of the mouth moved up pushing the air out of the nostrils.

Frogs also have a respiratory surface on the lining of their mouth on which gas exchange takes place readily. While at rest, this process is their predominate form of breathing, only fills the lungs occasionally. This is because the lungs, which only adults have, are poorly developed.

Who is studying animals in the wild considered to be somewhat experimentally out of control
KIM [24]

Studying animals in the wild is considered somewhat experimentally out of control because of several reasons.  

<u>Explanation:</u>

Study of wild animals can be done using several methods but none will be as effective as studying captivated animals. Using stationary cameras is a method to observe animals in the wild. The stationary nature of the camera makes it necessary for the animals to appear within the field of the camera.

This is difficult in places of low animal density. In addition to that placing camera at a longer distance to watch a larger area decreases the resolution of the images. When it comes to shallow water systems, the field imagery used to track the aquatic species frequently gets affected by issues like sun flicker.  

Unmanned aerial vehicles can also be used to track and study animals in the wild. This is good alternative but filming through dense canopies or turbid water is a limitation. Bio loggers can also be used for animal tracking but it is limited by weight since it has to be carried by animals.
