Semen is made up of a mixture of secretions from all of the following except? a) prostate gland b) bulbourethral glands c) testes d) seminal vesicles
Bulbourethral gland is not part of the secretions that made up the semen.
At the start of the internal section of the male reproductive organ, beneath the prostate gland, is the bulgurethral gland, also known as Cowper's gland. The bulbourethral glands have ducts that drain into the urethra, the tube through which both urine and semen enter. One of the tasks of the gland is to add fluid to semen during the process of ejaculation. They are made up of a network of tiny tubes, or tubules, and between the tubules are sac-like structures made of elastic and muscular fibers that provide the glands their structural support. Mucus, a viscous protein complex, is contained in droplets within the cells of the tubules and sacs. The clear, viscous fluid secreted by these glands serves as a lubricant, a flushing agent that cleans the urethra before to the ejaculation of the semen, and it may also aid to make the semen less watery and offer a proper living habitat for the sperm. The bulbourethral gland serves as a support system for the semen, as seen by the functions listed above.

Full Question:
The thickness of this sugar-protein scaffold of peptidoglycan can be used to separate most bacteria into two groups. In your tutorial, you want to illustrate to the students that the thickness of the peptidoglycan layer can be used by microbiologists to differentiate many bacteria by only using an easy staining method that all microbiologists will have to master. This staining procedure, known as the Gram stain, is based on the retention of dyes within the cell wall for a positive result or the rinsing away of the dyes and leakage of the membrane for a negative result. A thicker cell wall will allow for retention of dye crystals that will give the bacterial cell a blue-purple color (positive result), but the thinner cell walls will not allow for the retention of these crystals during rinsing, which will mean that these cells will then be colorless unless another dye that does not require interaction with the cell wall to maintain its retention is used (negative result). In addition to differences in cell wall thickness, Gram-positive and Gram-negative bacteria also differ in the proteins and lipids associated with their cell walls, as well as the composition of their cell membranes. Gram-positive walls are composed of an underlying cytoplasmic membrane, with the thick peptidoglycan layer on the outside offering support. Proteins anchor the membrane and the cell wall together to provide support and structure between the two. Gram-negative staining walls have a different layout. You try to explain in your tutorial that even though these bacteria stain "negative" they do have a thin layer of peptidoglycan sandwiched in between two lipid bilayer membranes.
Place each attribute into the bin of the bacterial group it belongs to, based on whether the bacterium is a Gram-positive or a Gram-negative cell.

The Study of Microbial Growth
-The Basis of Population Growth: Bacterial Cell Cycle and Binary Fission
Transverse binary fission is the mechanism used by bacteria to reproduce. In other words, one cell divides into two, and those two divide into four, and so on. A visible colony will emerge through several cell divisions within 10–24 hours once a single cell on a culture plate starts to divide.
-The Rate of Population Growth
The generation time is the length of time needed for one cell to divide. Generation times vary amongst different species; can be as low as 5 minutes and as lengthy as 30 hours. Bacteria evaluate their growth in cell counts rather than individual cell sizes. Growth is expressed in generation time.
Determinants of Population Growth
Over time, bacterial growth adheres to a growth curve—a predictably growing pattern.
Other Methods of Analyzing Population Growth
In liquid media, microbe growth causes turbidity. A spectrophotometer can be used to detect turbidity; however, not all bacterial cells are alive, therefore a higher absorbance indicates a higher bacterial cell count.
The six primary physical elements that influence the proliferation of microbes are highlighted in the following sentences. These elements are:1. Solutes and Water Acidity
2. Temperature
3. pH
4. Oxygen Requirements

At a chemical synapse, the release of neurotransmitter occurs in response to a graded depolarization of the synaptic terminal. True or false?.
Answer:
True: Neurotransmitters are released at chemical synapses in reaction to a gradual depolarization of a synaptic terminal.
The basic building block of the neurological system is indeed the neuron. A junction known as a synapses connects neurons in the neurological system. Neurotransmitters, which are released into synapses by neurons, are used for communication.
A stimulus that causes this nerve's resting membrane potential activates a presynaptic neuron. An action potential is then carried by the presynaptic nerve. The chemicals called neurotransmitters are being secreted into synapses together with action potential after passing via synaptic terminals.
Synaptic terminals get depolarized as a response of action potentials travelling thru the axon at those terminals. Depolarization causes the synaptic ion channels to open. In light of this, we may state that within a chemical synapse, neurotransmitters are released in response to a gradual depolarization of the synaptic terminal.

When forming a semi-solid gel such as gelatin, which molecules does the process of protein coagulation entrap?.
Answer:
When forming a semi-solid gel such as gelatin, water molecules does the process of protein coagulation entrap.
Explanation:
Since the proteins that make up gelatin, which is mostly generated from collagen, are significantly bigger than typically dissolved different molecules but are uniformly distributed all across the water, gelatin is just a colloid once it is dissolved in liquid. It is particularly a solution, a colloid that consists of solid particles spread throughout another material. The distributed phase refers to the inferior component of a colloid, in this example gelatin. Gelatin is just a liquid while it's heated and turns into a gel when it's cold. Another sort of colloid is a gel, which is created when a liquid is spread by a solid. The gelatin gel may be made liquid again by heating it. Furthermore, any colloid contains extremely big particles in solution. Since organic molecules may be much bigger than the majority of inorganic molecules, colloidal particles are particularly prevalent in biomolecules.
