Scientists use radiometric dating to determine the relative age of a new fossil.

Example:
<span>Glossopteris fossils are the most reoccurring fossils in most land masses. In Alfred Wegener’s Continental drift theory which he claims that the continents of the earth may have relocated themselves from their former positions. Which when you synthesize the whole continents you’ll have the “all-earth” or so-called Pangea. The super continent as Wegener’s continental drift theory suggests. These Glossopteris is event in many places mainly in Africa, South America, Australia, India, and Antarctica. That in the paleontological perspective can assert his theory that these organisms have been roaming and surviving all over this one super continent and were dispersed in, that's why they can be found in many places as mentioned.</span>

10. Brown pelicans are fish-eating birds. As a result of an El-Nino event, the population of brown pelicans in southern Californ
Firlakuza [10]

Answer:

Warmer ocean temperatures can cause fish to move to colder water farther from pelican nest sites

Explanation:

climate change is an important factor that affects the migration of fish from one place to the other. fish is seen to migrate/move from a warm water(heat) to a cold water/region so as to ensure their survival. the activities of man has affect the climate of our environment causing more heat the water bodies.

the gradual rise in the temperature of the ocean is forcing this species to leave their natural habitat.

Explain the process by which an attack of hay fever follows exposure to pollen
Bezzdna [24]

<span>Hay fever is a manifestation of allergic reaction from pollen, which is prevalent during haying season. Hay fever is commonly known as allergic rhinitis caused by an oversensitive immune system, particularly the lymphocytes, leading to a misdirected immune response. The body undergo a sensitization when one develops IgE antibodies and develop a strong TH2 response against pollen. Then, this newly develop IgE antibodies sticks to basophils and mast cells with no signs and symptoms yet. However, when one is expose again to pollens, mast cells will be activated and release mediators who are responsible for immediate vascular and smooth muscle reaction. After this, local clinical manifestation of hay fever will be observed. </span>

Ready-to-eat tcs food must be date marked if it will be stored for longer than:
Daniel [21]

Given what we know, we can confirm that ready-to-eat TCS food must be date marked if it will be stored for longer than 24 hours.

<h3>What is TCS food?</h3>
  • TCS food refers to food that must be stored in temperature-controlled environments to ensure safety.
  • These foods, if not stored properly and at the correct temperatures can cause sickness to the consumers.

<h3>Why does it need to be date-marked?</h3>
  • The reason the foods need to be date-marked is to relay information to the potential consumer as to by when the food should be consumed.
  • This is done to ensure that if stored correctly, the food does not have time to spoil and cause health risks for consumers.
<h3 /><h3 />

Therefore, we can confirm that ready-to-eat TCS food must be date marked if it will be stored for longer than 24 hours in order to <em><u>protect the </u></em><em><u>health </u></em><em><u>of the </u></em><em><u>consumers</u></em><em><u>. </u></em>

Mitosis and meiosis are processes involved in cellular reproduction. Which of the following describes an event that results from
forsale [732]

The event that results from mitosis but not from meiosis is: C) daughter cells that are identical to the parent cell.

Mitosis is the process of cell division where a parent cell divides to form two daughter cells. These cells have the same number of chromosomes as that of their parent and that is the reason why the process is also known by the name equational division.

Meiosis is the process where a cell divided into 4 daughter cells and they have half of the total number of chromosomes as that of their parent. Thus is why the process is also called reductional division. Meiosis does not occur in the somatic cells of the body but in the germ cells.
