Cells pass through a G2 checkpoint before entering mitosis. Ideally, if DNA damage is 2 detected, the cells do not enter mitosis

until the damage is repaired. Why is DNA damage repaired before cells enter mitosis? *
A.) So that another round of DNA synthesis does not have to take place

B.) So that the chromosomes can align at the metaphase plate during mitosis

C.) So that the cytoplasm can be divided equally between the two daughter cells

D.)So that healthy daughter cells are produced, allowing the organism to continue growing

I think that the answer is D. The cell employs the G2 checkpoint to check for DNA damage and completeness of DNA replication. This is done to ensure that cell division runs smoothly which means that healthy daughter cells, with complete and undamaged DNA, will be produced. At this point, all necessary repairs are applied.

Once a new finding is published in a scientific journal, it is still only preliminary and must undergo repeated testing to event
aalyn [17]

Answer:

The correct answer is - true.

Explanation:

The scientific journal is are the journals that publish the recent scientific findings or scientific experiments that produce new and appropriate results regarding particular experiment or research/

To confirm an experiment, published finding must be tested repeatedly by different scientists and researchers and see if the results are same in particular conditions.

Thus, the correct answer is - true.

Which provides long-term energy storage?
Lemur [1.5K]

Glycogen provides long-term energy storage.

Glycogen is an example of a carbohydrate which is a polysaccharide that acts as a long-term energy storage compound in animals.

<h2>Further Explanation </h2>
  • Living organisms require energy in order to undertake their daily activities such as growth and development, locomotion, gaseous exchange, etc. To do so they obtain nutrients for short-term and long-term energy source.
  • Carbohydrates are the major energy source for living organisms, however, living organisms may use other sources of energy such as proteins or fats when carbohydrates is out of stock or not available.  

Energy source in animals

  • Animals use simple carbohydrates such as glucose obtained from diet for short-term energy sources.
  • These simple carbohydrates may also be stored for future use in the form of glycogen, which makes glycogen a long-term energy source, to be used when need arises.
  • When glucose levels are low in the body hormones in the body trigger the breakdown of glycogen to glucose.
  • Other sources of energy such as proteins and fats are used when carbohydrates storage is depleted, for example during starvation.

Energy source in plants

  • In plants, on the other hand, simple carbohydrates are similarly used as a short term source of energy. Additionally, simple molecules such as glucose are stored in the form of starch for long-term source of energy for the plants.  

<em><u>Why other Choices are incorrect</u></em>:

<h3>Glucagon  </h3>
  • Glucagon is the hormone that increases the blood glucose level to avoid it from dropping below optimum level.
  • The hormone acts on the liver to stimulate the breakdown of glycogen to glucose, a process called glycogenolysis, and the glucose is released to the blood stream.

<h3>Glucose </h3>
  • Glucose is a simple carbohydrate classified as monosaccharides. It acts as the short term source of energy in both plants and animals.
  • It is readily broken down during the process of cellular respiration to yield energy in the form of ATP, which is then used to drive cellular processes.

<h3>Cellulose </h3>
  • Cellulose is an example of a complex carbohydrates known as polysaccharides.
  • It is found in plants cells lining the cell wall of all plant cells which is one of the key distinguishing feature between plant cells and animal cells.

It deployment strategies fall into two broad categories, which are ________:
Naddik [55]
Alliances fall into two broad categories: contractual (non-equity) and equity-based. projects, strategic suppliers, strategic distributors, and licensing/franchising (see Chapter 6 for definitions). These are also limited in scope and duration. Equity-based alliances call for a higher level of commitment. Examples include strategic investment (one partner invests in another as a strategic investor) and cross shareholding (both partners invest in each other). A joint venture is a special case of equity-based alliance that establishes a new legally independent entity (in other words, a new firm which is the JV) whose equity is provided by two (or more) alliance partners. Although JVs are often used as examples of strategic alliances, not all strategic alliances are JVs. Essentially, a JV is a “corporate child” given birth by two (or more) parent firms, such as SonyEricsson’s set up by Sony and Ericsson. A non-JV, equity-based alliance can be regarded as two firms “getting married,” but not having “children.” The Renault-Nissan alliance is such an example. Networks are also a form of strategic alliance. For the purposes of this chapter, we define strategic networks as strategic alliances formed by multiple firms to compete against other such <span>groups and against traditional single firms</span>
