Biology

Nady [450]3 years ago

Answer:

The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason.

New cells are born through the division of their “parent” cell, producing two “daughter” cells from one single “parent” cell.

Daughter cells start life small, containing only half of the parent cell’s cytoplasm and only one copy of the DNA that is the cell’s “blueprint” or “source code” for survival. In order to divide and produce “daughter cells” of their own, the newborn cells must grow and produce more copies of vital cellular machinery – including their DNA.

The two main parts of the cell cycle are mitosis and interphase.

Mitosis is the phase of cell division, during which a “parent cell” divides to create two “daughter cells.”

The longest part of the cell cycle is called “interphase” – the phase of growth and DNA replication between mitotic cell divisions.

Both mitosis and interphase are divided into smaller sub-phases which need to be executed in order for cell division, growth, and development to proceed smoothly. Here we will focus on interphase, as the phases of mitosis have been covered in our “Mitosis” article.

Interphase consists of at least three distinct stages during which the cell grows, produces new organelles, replicates its DNA, and finally divides.

frosja888 [35]

Glycolysis, the Krebs cycle and oxidative phosphorylation are the pathways of cellular respiration.

<h3>Pathway of cellular respiration</h3>

Glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation are the stages of glucose oxidation. Complete oxidation of one molecule of glucose results in the production of 38 molecules of ATP.

This process also results in the production of 38 molecules of water because the formation of phosphodiester bond between ADP and inorganic phosphate involves the splitting off of a molecule of water so we can conclude that glycolysis, the Krebs cycle and oxidative phosphorylation are the pathways of cellular respiration.

Explanation:

Genetically engineered foods (GE foods), or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering. Genetic engineering techniques allow for the introduction of new traits as well as greater control over traits when compared to previous methods, such as selective breeding and mutation breeding.[

Commercial sale of genetically modified foods began in 1994, when Calgene first marketed its unsuccessful Flavr Savr delayed-ripening tomato. Most food modifications have primarily focused on cash crops in high demand by farmers such as soybean, corn, canola, and cotton. Genetically modified crops have been engineered for resistance to pathogens and herbicides and for better nutrient profiles. GM livestock has been developed, although, as of 2015, none were on the market.

Which of the following would be LEAST likely in the fossil record? Which of the following would be LEAST likely in the fossil re
GREYUIT [131]

Answer:

The correct answer is desert-dwelling species.

Explanation:

Any preserved remains, trace or impression of anything, which was once living in the past is termed as a fossil. The examples of fossils comprise stone imprints of microbes or animals, bones, exoskeletons, shells, coral, remnants of DNA, the substances getting preserved in amber, and others.  

For the formation of fossils, the most essential condition is decomposition that takes place gradually, that is, at a slow pace. Thus, places like wet marshy areas will be the locations where the maximum of the fossils can be found as such places provide optimum conditions for slow mineralization and decomposition of bones.  

On the other hand, places like deserts would be the least likely to have a fossil record as deserts are devoid of optimum conditions required for the formation of fossils. In places like a desert, decomposition and demineralization of the components like bones take place at a brisk rate.
