The movement of water across biological membranes can best be predicted by D. water potentials.

We can describe water potential as a kind of pressure that is exerted by the biological membrane of the cell on the water molecules. It is the capability of water molecules to move from one place to another.

When the number of solutes will be more inside a cell as compared to the outside, the water molecules will enter the cell as a result of osmosis. On the other hand, when the number of solutes will be more outside of a cell then the water molecules will move outside of a cell. Such a type of movement of water is referred to as osmosis.

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>

How many trophic levels are there in the following food chain?
Dmitry_Shevchenko [17]

Answer:

4

Explanation:

In the food chain that is presented there are four trophic levels. The first level is occupied by the phytoplankton, which is the producer, thus it is at level one on the energy pyramid. Second comes the shrimp, which is feeding on phytoplankton, but is prey upon by numerous other species, thus it is on the second level in the energy pyramid. In the third level of the energy pyramid we have the perch. It is a small carnivore, and it feeds upon the shrimp and many other small prey animals, but it is also preyed upon by many larger species. The pike and the osprey are occupying the fourth level in the energy pyramid. They are both predators, and they prey on on the likes of the perch and many other small fish and animals, but they are not at the top of the food chain, as they also have predators above them and prey on them.

A chimpanzee has 48 chromosomes. When performing meiosis, one chromosome does not split properly in Anaphase II, causing one cel
Schach [20]

Answer:

The mutated cell will have 25 chromosomes.

Explanation:

Meiosis is a cell division process in sexual reproduction which involves two successive divisions of a cell having a diploid (2n) number of chromosomes into four daughter cells having a haploid (1n) number of chromosomes.

Meiosis consists of two successive nuclear divisions, meiosis I and meiosis II. Each division consists of these stages: prophase, metaphase, anaphase, and telophase.

Anaphase consists of anaphase I and II. During anaphase II, the centromeres linking the two pairs of chromosomes which are called chromatids separate, and the sister chromatids move toward the opposite poles of the cell and are now called chromosomes.

Therefore in the chimpanzee having 48 chromosomes, after underoing meiosis, each daughter cell will have 24 chromosomes. If there is a case of non-separation of one chromosome, the cell will have 1n + 1 chromosomes i.e. 24 + 1 = 25 chromosomes.
