In the liver, bile salts are formed. Because of their low surface tension, this contributes to the emulsification of fats found in the intestine and their absorption from the GI tract. These are bile’s components. It is because of the bile salts which give bile the ability to emulsify, mix, lipid in the aqueous environment in the intestine. Bile is the one responsible for the efficient digestion of lipids. Bile is secreted in the gallbladder down to the small intestine. It then breaks dietary fats into smaller particles called emulsification in the small intestine. The bile’s function is in the completeness of the digestion and absorption of fat.
Phospholipids and triglycerides both _____.
Which of the following best describes computer modeling in biology?
a.A computer is used to create a spreadsheet showing the relationship of the algae population in a lake to the nitrate pollution
b.A computer is used to simulate the growth of algae in a lake due to increasing nitrate pollution.
c.A computer is used to calculate a scale of a lake’s turbidity due to algal growth from too much nitrate pollution in the water.
d.A computer is used to store data and create a database of the changing algae populations in a lake due to nitrate pollution.
Answer:
The answer is B
Explanation:
A computer model is mostly used for simulations. In other words, the computer program can generate scenarios showing the response of the organisms under study when we enter variations in the conditions such as temperature, salinity and rainfall or variations in resources, such as prey type or availability of nesting sites or nutrients.

Which of the following actions would be most effective in decreasing the amount of carbon dioxide in the atmosphere while increasing the amount of biodiversity in an area?
Planting more trees to absorb more of the carbon dioxide from the atmosphere.
Converting forests into housing developments to increase the amount of carbon dioxide used.
Digging up native prairies so more crops which use more carbon dioxide can be grown.
Sowing beans or other legumes along with corn to decrease carbon dioxide fixation.
Planting more trees, or reforestation, is the most effective action in decreasing the amount of carbon dioxide in the atmosphere while increasing biodiversity. It allows trees to absorb carbon dioxide via photosynthesis and supports ecosystems with high levels of diverse life forms.
Explanation:The action most effective in decreasing the amount of carbon dioxide in the atmosphere while simultaneously increasing the amount of biodiversity in an area would be planting more trees. This process is known as reforestation. Trees naturally absorb carbon dioxide from the atmosphere during photosynthesis, a process by which they convert carbon dioxide and sunlight into oxygen and glucose. Moreover, forests are rich ecosystems that can support a high level of biodiversity, including various species of plants, animals, and microorganisms.
On the other hand, converting forests into housing developments, digging up native prairies, or sowing beans along with corn, although these actions might temporarily sequester some carbon dioxide, they generally lead to the reduction of biodiversity and destruction of ecosystems. Therefore, they are less effective strategies in the long term.

A substance that can elicit an immune response from a lymphocyte is called a(n) ______.
In biology, a substance that elicits an immune response from a lymphocyte is known as an antigen. These substances could be on the surfaces of varied cells which the immune system identifies as foreign, thereby eliciting an immune reaction primarily involving lymphocytes like T-cells and B-cells.
Explanation:A substance that can elicit an immune response from a lymphocyte is commonly known as an antigen. Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. The immune system recognizes any cell with these substances on its surface as foreign, and it can elicit an immune response.
Ideally, lymphocytes come to play, where T and B cells, components of lymphocytes in our body, react to these antigens. T-cells directly attack the foreign cells while B-cells produce antibodies that target the antigens to neutralize or eliminate them.

Consider the activity and specificity of the three enzymes. Pepsin is most active in the human ________ and helps to digest __________. A) mouth; starch B) mouth; protein C) stomach; protein D) small intestine; lipids
C) stomach; protein
Answer:
The correct answer is C) stomach; protein
Pepsin is an endo-peptidase i.e. it breaks down peptide bond and thus helps in breaking down proteins or larger polypeptide chains into smaller chains.
It is secreted as pepsinogen (zymogen) by chief cells in the stomach. HCl (hydrochloric acid) released from parietal cells in the stomach converts pepsinogen into its active form pepsin.
It usually cleaves at the C-terminal side of amino acids such as tyrosine, phenylalanine, and tryptophan.
Which operant conditioning process must researchers use to encourage closer and closer approximations of a target behavior? A. stimulus generalization B. acquisition C. extinction D. shaping
The correct answer is D. Shaping.
Target behaviour is termed as the behavior which is being identified to change the behaviour which is prescribed.
The behaviour can be identified by topography or by function.
There are different types of behaviours, for example,
1. Agressive- the act of anger which is unplanned tends to hurt something or someone.
2. Assertive.
3. Passive.
4. Passive-aggressive.
The basic kind of behaviour is operant behaviour because it acts or operates in an environment. The other one is consequence influence.
Do bacterial cell membranes have cholesterol
Final answer:
Bacterial cell membranes typically do not contain cholesterol, but have hopanoids instead; however, there are exceptions such as some pathogenic bacteria that utilize host cholesterol.
Explanation:
The question being asked is whether bacterial cell membranes have cholesterol. In general, the membranes of eukaryotic cells, such as those in animals and plants, are enriched with cholesterol along with other types of lipids. However, bacterial membranes do not typically contain cholesterol. Instead, bacteria contain hopanoids, which are sterol-like molecules that can be thought of as bacterial equivalents to cholesterol in eukaryotic cells. Certain special cases exist, such as some species of Mycoplasma, which require cholesterol from their host for growth, and some bacteria that enhance their membranes with sterols when they lack a cell wall, like in the phylum Tenericutes. Additionally, pathogenic bacteria like Mycobacterium tuberculosis and Chlamydia trachomatis utilize host cholesterol for their growth and infection processes.

Why might scientists be interested in making transgenic organisms?
Transgenic organisms glow in the dark and provide a light source in dark places.
Transgenic organisms can produce a desired product that may benefit other organisms.
Transgenic organisms can be used to cut strands of DNA molecules into fragments.
Transgenic organisms can be used as a medium to transfer foreign DNA into a host cell
The right answer is Transgenic organisms can produce a desired product that may benefit other organisms.
A transgenic organism contains DNA combining stably integrated in all its cells. In other words, the organism, be it a plant, an animal or a microorganism, has a new piece of DNA embedded in it. a chromosome in each of its cells. This "new piece" of DNA usually contains a gene from another organism (plant, animal or other) that has been modified to be expressed in the new organization. A transgenic organism may even possess the DNA of another organism of the same species. The inserted gene can be called the transgene.
Currently, diabetics are treated by injecting insulin from either a healthy human donor or cultures of genetically modified (transgenic) bacteria that secrete the protein.
