Answer:
Evolution of management is the concept that was developed in the early days of men when the realization was made that we must live in groups for the survival.
Explanation:
- Since men saw and realized that they need to live in groups, mighty men in the past were able to organize the masses, share them into various groups. The sharing was done accord to the masses' strength, mental capacities and intelligence.
- The evolution of management section is mainly divided into four sections:
- Early Management Thought
- The Scientific Management Era
- The Social Person Era
- The Modern Era
Answer:
B) Na+
Explanation: Na+ molecule is polar, oxygen and carbon dioxide are nonpolar molecules. The cell membrane is a <em>phospholipid bilayer</em> made up of lipid molecules with polar and nonpolar ends. Since it is a bilayer, two phospholipid layers are arranged, one on the other in such a way that one faces the back of the other. The non polar ends are away from outside and inside of the cell, while the polar ends faces towards all the molecules inside and outside the cell.
Since polar-polar molecules repel each other, Na+ can't pass through the cell membrane easily. So it uses the proteins attached the cell membrane inside and outside to transport such molecules by using energy in terms of ATP.
Answer:
Pentose sugar
Explanation:
phosphate and pentose sugar are the backbone of a dna strand
In the deep layers of the ocean, various distinct kinds of species are found like fangtooth fish and vampire squid, to sea urchins and coffinfish.
One of the probable adaptation, which is not fully understood in the deep sea is gigantism. This refers to the ability of animals to become highly enormous in size. A well-known illustration is a giant squid, and others, like giant isopod, the kings of herrings selfish, and the colossal squid.
One of the possible reason of gigantism is the tendency of the species in the deep sea to live for long years, that is, for decades or for even centuries. As food is not abundant in the deep zones, thus deep sea creatures have evolved some interesting mechanisms of feeding.
In the non-existence of photosynthesis, the majority of food comprises of detritus, that is, the decaying leftovers of algae, microbes, animals, and plants from the upper layers of the ocean. Apart from that, the corpses of large animals, like whales that sink to the bottom give irregular but huge feasts for deep-sea animals.
It is also assists in creating body chemicals like hormones and enzymes that are needed for normal function. It provides energy (like carbohydratesdo) and keeps the immune system strong. Proteins are made up of amino acids, and dogs require 22 amino acids to make necessary proteins.
