Which of the following statements is not true of the circulatory system and its transport of nutrients?
a. Water-soluble nutrients leave the small Intestine via lymph.
b. Nutrients that leave the small intestine via blood are delivered first to the liver.
c. Lymph empties into the blood just before the blood reaches the heart.
d. Lymph is formed from fluid that Is forced out of capillaries by blood pressure.
Answer: b. Nutrients that leave the small intestine via blood are delivered first to the liver.
Explanation:
Lymph is a clear fluid that leeks out from the interstitial spaces of the cells and this comprises of electrolytes, blood proteins, and antibodies. It is pushed towards the heart from the lymphatic vessels. The nutrients from the small intestine are drained into the bloodstream and they are circulated to all parts of the body and not directly destined towards the liver.

9. How did life on Earth change from one period of geologic time to the next?
Answer:
Scientists use the geologic time scale to illustrate the order in which events on Earth have happened. ... They used relative dating to divide Earth's past in several chunks of time when similar organisms were on Earth. Later, scientists used absolute dating to determine the actual number of years ago that events happened.
Life on Earth greatly change from one period to the next of geologic time.
The life on Earth change from one period of geologic time to the next because major changes appear on the surface of earth. Great changes in the environmental conditions leads to the change in the distribution of organisms as well as extinction of various organisms on which other organisms depend.
Due to this extinction of different organisms imbalance occurs within the ecosystem so we can conclude that life on Earth greatly change from one period to the next of geologic time.

One weakness of the human microbiome project is its use of Sanger Sequencing instead of modern metagenomic techniques. it's underrepresentation of non-US born people. it's inclusion of multiple lifestyle attributes. its sampling of people with a wide variety of diets preventing analysis of risk groups. the lack of information sharing from the project's findings.
Answer:
The correct answer is - It's a sampling of people with a wide variety of diets preventing analysis of risk groups.
Explanation:
The correct answer among the given option would be that people with more diverse diet variety would be preventing the analyzing the risk groups. It is known that the human microbiome project believes that every individual experiences a specific and unique effect of the microbiome.
Even in the case of two distinct organisms have the same microbiota will experience different effect and show different characteristics to one another due to varieties and difference in their diet.

Which is not a reason why organisms are classified into Domains and Kingdoms?
Answer:
for a better study of organisms
Explanation:
Organisms are classified into domains and kingdoms based on their cell type, their ability to make food, and the number of cells in their bodies.
Domains and kingdoms are the highest categories of classification. It is usually used to classify organisms to make it simple for their identification. It is not classified only to study the organism better.
What are domain and kingdom?A domain is the highest category of classification and a kingdom is a second-highest category.
Living things are placed in these categories according to their way of obtaining food, the number of cells, types of nuclei, etc.
It is used to avoid confusion between the organism and to show that the organisms are related to each other.
Thus, it can be concluded that it is not used not only study but for other purpose also.

Petrus brings his 87-year old grandmother to the emergency department where you work. His grandmother has a fever, is dehydrated and confused, and complains of pain when urinating. Petrus reports that she has not been eating or drinking, but she has no signs or symptoms of gastrointestinal distress. You request blood samples and also a urine sample. You decide to keep Petrus' grandmother in the hospital so that she can be given intravenous fluids. You also want to wait for the lab test results before you decide whether she required additional treatment or if she can return home.
1. When Petrus' grandmother's test results are sent to you, you discover that while her blood work is normal, her urine has Gram-negative bacilli in it. Based on this, you know that the cells are:______.
a) stained blue and are cylindrical in shape.
b) stained purple and are cylindrical in shape.
c) stained pink and are spherical in shape.
d) stained pink and are cylindrical in shape.
e) stained green and are oval in shape.
2. Petrus asks you what the Gram-negative result means and you explain that the bacteria causing his grandmother's UTI:____.
a) have a thin cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
b) have a thick cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
c) have no cell wall but they have a thick outer membrane which makes the cells less sensitive to the antibiotic penicillin.
d) have a thin cell wall and an inner cell membrane which makes the cells less sensitive to penicillin.
e) have no cell wall which makes the cells more sensitive to the antibiotic penicillin.
Answer:
d) stained pink and are cylindrical in shape.
b) have a thick cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
Explanation:
Gram-negative bacteria are bacteria that do not retain the crystal violet stain. So they stain in pink and they have an outer cell membrane unlike gram positive bacteria.
