When the blood glucose level rises after a meal, the first organ to respond is the pancreas.
Insulin is a hormone produced by the body to regulate blood sugar levels. When the glucose level rises in the blood, the insulin secreted causes glucose to be transported to the cells from the blood. In the cells, the extra glucose is used accordingly and the cells of the liver and muscles can store it as glucagon.
Hence, when the blood glucose level rises after a meal, the pancreas makes insulin to balance the blood sugar levels.

What condition will increase the diffusion of molecules, such as neurotransmitters?
An increase in the number of neurotransmitters exocytosed by the presynaptic axon will increase the diffusion of molecules such as neurotransmitters.
what are neurotransmitters?
Any of a group of chemical agents released by neurons (nerve cells) to stimulate surrounding neurons, muscle cells, or gland cells allows impulses to be transmitted from one cell to the next throughout the nervous system. This is known as a neurotransmitter, also known as a chemical transmitter or chemical messenger.
These neurotransmitters are stored in synaptic vesicles of the axon terminals and are released during transmission of impulses from one neuron to another.
Neurotransmitter molecules are instantly destroyed by enzymes in the synaptic cleft after being released and binding to postsynaptic receptors; they are also absorbed by receptors in the presynaptic membrane and recycled.
Hence, if they are released in large amounts from the synaptic vesicles their diffusion will increase automatically.

What is the hybridization of the central atom in the xenon tetrafluoride molecule?
The central atom has 6 electron pairs out of which two are lone pair electrons. The hybridization in Xenon is sp3 d2 because there is a migration of two electrons of p to d orbital which results in the formation of a sigma bond with F.
What is meant by hybridization?Whenever two atomic orbitals in a molecule merge to generate a hybrid orbital, the energy of the orbitals of the single atoms is redistributed to give orbitals of equivalent energy. Hybridization is the name of this procedure. In the hybridization process, atomic orbitals with similar energies are mixed together; this often includes the fusion of two s orbitals, two p orbitals, or the mixing of an s orbital with a p orbital or a d orbital.
Hybrid orbitals are the novel orbitals that result from this process. However, hybrid orbitals are also very helpful in describing the geometry of molecules and the characteristics of atomic bonds. Let's immediately examine the example of an atom of carbon. This atom creates four single bonds in which three valence-shell p orbitals and one valence-shell s orbital combine.
The result of this combination is the creation of four comparable sp3 mixes. Around the carbon, which is bound to four distinct atoms, they will be arranged in a tetrahedral pattern.
Therefore, the molecule has sp3 d2 hybridization.

Hormones from the adrenal and gonadal sytems are eliminated through the urine or bile in the liver.
Unbound steroid hormones from the gonadal and adrenal glands are transformed in the liver, where they become inactive, and subsequently eliminated through the bile or urine. The lungs, cell metabolites, or feces do not contain adrenal or gonadal steroid hormones. The steroid hormones are broken down by several tissues, but mostly the liver, into physiologically inactive byproducts that are primarily excreted in the urine, although some are also removed via the bile and, finally, the feces. Analysis of urine steroids may aid in the diagnosis of endocrine disorders. The liver is the primary site of steroid metabolism.

Why are some bacteria, such as those of the genera mycobacterium and nocardia, not effectively stained with the gram stain?
Answer:
Some bacteria, such as those of the genera mycobacterium and nocardia, not effectively stained with the gram stain because they have too much peptidoglycan in their cell walls.
Explanation:
Across most types of bacteria, the cytoplasmic membranes is encased in a hard material called peptidoglycan. It helps maintain cell shape all across the life cycle and shields bacterial cells against environmental stress. The production of peptidoglycan has a significant role in controlling bacterial cell division. The bacterial cell wall's peptidoglycan plays a structural role by providing structural support and balancing the cytoplasm's osmolarity. Additionally, peptidoglycan participates in binary fission throughout bacterial cell division. Christian Gram, a microbiologist, developed a test in 1884 which might identify whether a bacterium possessed a strong, mesh-like membrane known as peptidoglycan. Numerous bacteriophages, eukaryotic, and bacteria all generate peptididoglycan hydrolases.
