Answer:

  • Elements are made up of only one type of atom.
  • Each element has a unique chemical symbol.
  • Elements can be identified by their atomic number

Explanation:

Chemical elements are the basic constituents of all substances. At the microscopic level, the following definition can be made: A chemical element is the set of atoms that have the same atomic number. The chemical element is formed of only one type of atom, has a unique and unique chemical symbol and can be identified by its atomic number.

Currently about 115 chemical elements are officially recognized, with properties quite different from each other and others that resemble each other. Therefore, the elements were organized in ascending order of atomic number, forming a set that is known as the Periodic Table.

What is the ultimate measure of evolutionary success?
vfiekz [6]

There is only one measure of "evolutionary success": having more offspring. A "useful" trait gets conserved and propagated by the simple virtue of there being more next-generation individuals carrying it and particular genetic feature "encoding" it. That's all there is to it.

One can view this as genes "wishing" to create phenotypic features that would propagate them (as in "Selfish Gene"), or as competition between individuals, or groups, or populations. But those are all metaphors making it easier to understand the same underlying phenomenon: random change and environmental pressure which makes the carrier more or less successful at reproduction.

You will sometimes hear the term "evolutionary successful species" applied to one that spread out of its original niche, or "evolutionary successful adaptation" for one that spread quickly through population (like us or our lactase persistence mutation), but, again, that's the same thing.

Pancreatic and intestinal enzymes operate optimally at a pH that is slightly alkaline, yet the chyme entering the duodenum from
lora16 [44]

Answer: By the help of the fluid delivered from the pancreas.

Explanation:

The human body is a very complex system consisting of many organ and organ system.

One of those systems is the the digestive system. By the help of this system the digestion and absorption of food takes place.

There are numerous number of enzymes involved in the digestion of the food released by various organs. The pancreatic and intestinal enzymes are secreted that work at alkaline pH, but the chyme that is secreted from the deodenum is slightly acidic yet they work together.

This is because pancreas pour enzyme into small intestine which is alkaline  and it then secretes huge amount of sodium bicarbonate which neutralizes the acidity of the stomach and makes the pH optimum for the digestion of food.
