why would you expect none of the organisms you inoculated onto mm1 without glucose to grow?
You would expect none of the organisms inoculated onto MM1 without glucose to grow because glucose serves as the primary source of energy for many microorganisms. MM1, or minimal media 1, is a type of growth medium used to culture organisms in a controlled environment.
It typically contains essential nutrients, such as nitrogen, phosphorus, and sulfur, as well as a carbon source, like glucose, to support microbial growth.
In the absence of glucose, the organisms would lack a crucial energy source needed for metabolic processes, cellular maintenance, and reproduction. This energy deficit would result in limited or no growth of the inoculated organisms.
Furthermore, some organisms might be unable to utilize alternative carbon sources present in the minimal media, making the lack of glucose even more detrimental to their growth. For these reasons, it is reasonable to expect that none of the organisms inoculated onto MM1 without glucose would grow, as they would not have the necessary energy source to support their growth and reproduction.
In summary, glucose is a critical energy source for many microorganisms, and its absence in MM1 growth medium would prevent the growth of inoculated organisms due to their inability to perform essential metabolic processes and reproduce.

Filtered substances pass from the blood in the glomerulus into the renal tubule, while secreted substances move from the blood in the peritubular capillaries into the renal tubule. Reabsorbed substances move from the renal tubule back into the blood in the peritubular capillaries.
Therefore, the amount of a substance that is excreted in the urine is equal to the amount that is filtered (which is the initial amount that enters the renal tubule), plus the amount that is secreted (which is added to the renal tubule from the peritubular capillaries), minus the amount that is reabsorbed (which is removed from the renal tubule back into the peritubular capillaries).

the monomers of lipids move into the epithelial cells of the intestine via what type of transport?
The monomers of lipids, also known as fatty acids and glycerol, move into the epithelial cells of the intestine through a process called facilitated diffusion.
Facilitated diffusion is a type of passive transport where molecules move from an area of higher concentration to an area of lower concentration with the help of transport proteins. In the case of lipid absorption, transport proteins on the surface of the epithelial cells bind to the monomers of lipids, allowing them to pass through the cell membrane and into the cell. From there, the monomers are reassembled into lipids and packaged into chylomicrons, which are transported through the lymphatic system and eventually enter the bloodstream.
The monomers of lipids move into the epithelial cells of the intestine via a type of transport called passive diffusion. In this process, lipid monomers, such as fatty acids and monoglycerides, move from an area of high concentration to an area of low concentration without the need for energy input. The monomers pass through the cell membrane, facilitated by the presence of lipid-soluble molecules, and enter the epithelial cells lining the intestine. Once inside, they can be further processed and absorbed by the body for various functions, including energy production and cell maintenance.

The balance between fusion and fission is likely a major determinant of mitochondrial (choose all that apply): number, length, color, degree of interconnection, degree of emotional distance
The balance between fusion and fission is a major determinant of mitochondrial number, length, and degree of interconnection.
1. Number: Fusion refers to the process where two mitochondria combine to form a single, larger mitochondrion, while fission is the division of a single mitochondrion into two smaller ones. An equilibrium between these processes helps maintain a stable number of mitochondria in the cell, ensuring optimal functioning.
2. Length: Mitochondrial fusion and fission play a crucial role in regulating mitochondrial length. Fusion can lead to an increase in length, as two mitochondria merge into a single, elongated one. Conversely, fission can reduce the length by dividing a mitochondrion into smaller parts.
3. Degree of interconnection: The interconnectedness of the mitochondrial network is influenced by fusion and fission events. Fusion helps create an interconnected mitochondrial network by merging individual mitochondria, while fission can fragment the network by separating them.
Color and degree of emotional distance are not relevant factors in the context of mitochondrial fusion and fission, as these terms do not apply to cellular structures and processes.
