At what point during normal dna replication is genetic material lost at the telomeres?
vovangra [49]

The point during normal DNA replication at which genetic material is lost at the telomeres is during joining of adjacent Okazaki fragments.

<h3>What is DNA replication?</h3>

DNA or deoxyribonucleic acid replication is the process that is used by the cells to produce new cells that has a replica of the parent cells.

During DNA replication, genetic material lost at the telomeres due to joining of adjacent Okazaki fragments which are short sequences of DNA nucleotides.

Therefore this shortening of telomeres is due to the 'end replication problem'.

22. What type of reaction is Cellular Respiration?<br> (exerganic or endergonic)
FrozenT [24]

Answer:

Cellular Respiration is an exergonic reaction.

Explanation:

An exergonic reaction is a type of reaction where energy is released to the surroundings. This reaction happens spontaneously and does not require energy to proceed. These reactions form more stable bonds by breaking less stable chemical bonds and release energy. Catabolic reactions are exergonic reactions. Here energy is released by the breaking down of larger molecules into smaller ones. Cellular respiration is an example of an exergonic (catabolic) reaction. It is the conversion of glucose in the presence of oxygen into carbon dioxide and water. The energy released is used for cell activities. Another example is the breaking down of hydrogen peroxide into water and oxygen in the cells.

An endergonic reaction is a type of reaction where energy is absorbed from the surroundings. These reactions form less stable bonds by breaking more stable chemical bonds using energy. Anabolic reactions are endergonic, in which small molecules combine to form larger ones. An example of an anabolic reaction is photosynthesis, where carbon dioxide and water are used to produce glucose and oxygen by using energy from sunlight. Another example is the reaction of glycerol with fatty acids to make lipids.

Molly likes to eat oranges year round, but her friends tell her that she is not living sustainably by doing that. Why is that?
liubo4ka [24]

The correct answer is - oranges take a long time to grow.

The orange tree is a tree needs several years in order for it to be able to develop a fruit, usually three to four years, though it will produce only few fruits in that period, and will only produce more after the tenth year when the tree is fully matured.

The fruit itself also takes a while to mature, pretty much a whole year. So when the friends of Molly say that she is not living sustainable lifestyle it is because she eats oranges all the time, though they are only harvested in one particular part of the year, and it is a long process, referring to that the she uses more than a tree can produce.

Teresa woke up and looked out the window. She could see the Sun just above the eastern horizon. If she looks out the window exac
tamaranim1 [39]

Answer:

In about the same place

Explanation:

The sun rises in the east and sets in the west each day because the earth rotates toward the east making a complete turn every 24 hours while the sun actually stays in its position at the center of our solar system. Therefore, as the earth spins clockwise, the sun reaches different parts of the earth at different times as the eastern part gets the sun rays first before it passes to the other parts of the earth.
