The thoracic cavity is situated superior to the abdominopelvic cavity and separated by the diaphragm. therefore, the diaphragm creates what type of plane?
The thoracic cavity is placed superior to the abdominopelvic cavity and separated by the diaphragm. therefore, the crosswise plane is made by the diaphragm.
The diaphragm, a fragile muscle that separates the chest from the belly, is found at the bottom of the chest. after you inspire, it flattens and shrinks. As a result, the lungs expertise a vacuum result that attracts air in. The diaphragm relaxes and therefore the air is forced out of the lungs after you exhale. Your diaphragm flattens and tightens as you inhale, slippy down toward your abdomen. Your chest will expand (grow bigger) and attract air as a result of this movement, which causes a vacuum in your chest.

The meiotic mechanism by which the fetus inherits the extra chromosome 21 is non-disjunction.
Chromosome is the compact form of genetic material. it consists of DNA and histone proteins. The genetic material is inherited from parents to offspring in this form. Each chromosome consists of two sister chromatids joined at the center by a kinetochore.
Non-disjunction is the failure of the homologous chromosomes or the sister chromatids to separate equally during meiosis. The result is the abnormal distribution of the chromosomes.

What is an important regulation process that connects various parts of a system?
Answer:
An important regulation process that connects various parts of a system is feedback.
Explanation:
A reaction inside a biological system—a molecule, tissue, species, or population—that affects the behavior or performance of that system is known as feedback. It essentially involves the regulation of a metabolic pathway by the activity's byproducts.
Both positive and negative feedback is possible. Negative feedback is indeed a component of any feedback mechanism that keeps things in balance. Positive feedback in biology occurs far less frequently. Whenever a change in variable results in a reaction that undoes the original change, this is known as negative feedback. A reaction is generated by a change in a factor when there is positive feedback. For instance, a warm-blooded species like a whale keeps a greater body heat to improve the internal equilibrium and while a cold-blooded animal such as fish retains a lower temperature of the body in accordance with the surrounding environment.

According to the question,
The number of mature seeds are formed in the fruit = 50 (Given)
The number of pollen grains land on a stigma = 100 (Given)
We know that, one male gamete will fuse with one egg nuclei to form zygote. In the double fertilization process, one gamete fuses with polar nuclei and forms endosperm. The other male gamete fuses with the egg to form zygote then it gives rise to seeds.
∴ 50 male gametes fuse with egg cells to form 50 seeds and other 50 male gametes fuse with 100 polar nuclei.
Thus we can conclude that, 100 pollen grains land on a stigma, and 50 mature seeds are formed in the fruit, it indicates 50%success: 50 sperm fertilized 50 eggs, and 50 sperm fused with 50 polar nuclei.
