Sympathomimetics stimulate the sympathetic nervous system, causing vasoconstriction and reducing inflammation in nasal tissues. This relieves nasal congestion associated with colds and allergies.
Sympathomimetics work by activating receptors in the sympathetic nervous system, which controls various involuntary functions in the body, including the constriction of blood vessels. By constricting blood vessels in the nasal tissues, sympathomimetics reduce blood flow and fluid leakage, which reduces inflammation and congestion. Sympathomimetics can be administered orally, topically, or by injection. Common sympathomimetics used for nasal congestion relief include pseudoephedrine and phenylephrine. However, sympathomimetics can have side effects such as increased blood pressure and heart rate, so they should be used with caution and under the guidance of a healthcare provider.

in which Domain & Kingdom would scientists classify an organism, whose cells contain a nucleus, has cell walls made of chitin, and does not have chloroplasts?
Answer:
The correct answer is -
Domain: eukarya
kingdom: fungi
Explanation:
A cell with a nucleus and cell wall made up of the chitin and does not have chloroplast, are all the characteristic features of an organism of kingdom fungi which is a group of eukaryotic organisms.
The cells with the nucleus are grouped in the domain eukarya while the prokaryotic organism does not carry a nucleus in their cell and divided into Archaea and bacteria. The chitinous cell wall without any chloroplast in the cell is one of determining features of the fungi kingdom.
What produces all of the light in the universe?
Answer:
Source of Light in UniverseAlthough the Sun doesn't light up the other stars, it does provide the daylight here on Earth; and the moon and planets we see are illuminated by that same sunlight.

Why do cells continue to divide in adult organisms?
Answer:
Although most of the tissues in adult organisms maintain a constant size, the cells that make up these tissues are constantly turning over. Therefore, in order for a particular tissue to stay the same size, its rates of cell death and cell division must remain in balance.

how does cell division help in growth and development of somatic cells and in gamete formation?
════════ ∘◦❁◦∘ ════════
[tex] \mathbb{CELL\:DIVISION\:(MITOSIS)} [/tex]
════════════════════
Well, im not sure what somatic cell is. But, the reason why cell division help in growth and development is because the main goal of cell division is to make more cells right? This is also why we keep growing (like taller/bigger) because more cells in our body because of that cell division.
#see pic of how cells in our body divide during mitosis
#sorry i borrow this ans for my latex experiment :v
════════════════════
Mitosis occurs in somatic cells this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.

9. The enzymatic redox reaction process in Krebs Cycle produces what molecule?
A. Cytochrome oxidase C. Oxaloacetate
B. Succinate Acetate D. Oxaloxide
10. During electron transport chain, energy from the electrons of NADH and FADH2 is used in the process
chemiosmosis to __________.
A. reduce NADH to NAD+ C. phosphorylate ADP to ATP
B. reduce FADH2 to FAD D. pump hydrogen ions across the membrane
Answer:
7. D. breaking the glucose molecule to produce acetyl CoA
8. C. Oxaloacetate
10. phosphorylate ADP to ATP
Explanation:
Cellular respiration is the metabolic process by which energy in form of ATP is obtained in a cell. However, it occurs in three major stages namely: glycolysis, Krebs cycle and electron transport chain (oxidative phosphorylation).
- Glycolysis is the process where glucose is broken down to produce pyruvate, which is then processed into acetyl coA before it enters the next stage (Krebs cycle).
- Krebs cycle is the stage where series of REDOX reactions occur to produce OXALOACETIC ACID as a final product, which accepts acetyl coA for another cycle to begin.
- Electron transport chain (ETC) uses the energy derived from the electron carriers energy NADH and FADH2 to phosphorylate ADP to ATP in a process called CHEMIOSMOSIS.
