The correct answer for this question is "more water is lost than enters the body". Isotonic Fluid Loss can also be referred to as Dehydration. Dehydration is the state of losing too much water than absorbing the required water that the body needs. Based on the given situation, a patient with flu and reports about five to six loose stools a day can lead a patient to dehydration because of his continuous pooping. Water lost must be replaced, so that the patient won't be dehydrated.
Answer:
The difference between plant growth and animal growth are: In plants growth is unlimited and in animals growth is limited
Explanation:
Growth in plants are localized at certain points such as shoot tip, root tip etc. New organs continue to appear throughout the life of plants. In animals cells divide until they can't anymore or grow to old.
Answer:
With few exceptions, all cells in a person’s body have the same DNA and genes. As cells divide and grow different genes are expressed, resulting in different cell types. As cells divide and grow different genes are expressed, resulting in different cell types.

Answer:
A sea sponge 760 million years old
Explanation:
It's unclear exactly how long sea sponges have been around, but they are at least old enough to be the longest-existing creatures on Earth, outside the realm of microorganisms (like bactery). The oldest evidence of a sea sponge found was a fossil discovered just last year in a 760-million-year-old rock. This beat the previous record for oldest sponge fossil, a 635-milloon-year-old sponge discovered in 2009. There may be still older fossils yet to find. But finding an older species is unlikely,as these simple organisms appear to be the progenitors of much more complicated life, including the first multicellular animals.
Answer:
B
Explanation:
The Ames test is a bacteriological technique commonly used to determine if a particular chemical or substance can cause mutations. To achieve this, researchers use bacteria (commonly <em>Salmonella typhimurium</em>) as this bacteria strain is unable to grow in a medium that does not contain histidine (a very important amino acid in the biosynthesis of proteins). If the studied substance is able to cause mutations, bacteria will mutate, and they will be able to grow on that particular media even if they don’t have histidine for their metabolism. Therefore, if there are colonies growing, the chemical being tested is mutagenic.
I hope this clarify your inquiry.
