<span>These species probably belonged to the homo neanderthalensis species, these are a type of neanderthal species that have evolved in the past. Recent studies made by scientists and archaeologists have concluded that brain size of humans reduce in size through evolution. <span>

Immune tolerance is the lack of capacity to increase the
reaction to antigens. The tolerance can either be natural or “self” tolerance. On
the other hand, licensing is a kind of protein that lets replication for cells.
They usually happen with eukaryotic cells and they begin with the replication
of DNA.
The term ''tissue'' refers to a group of similar cells. Being a combination of equal cells, a tissue has the same function in any part of the body.
The four types of tissues are:
. The epithelial tissue
. The connective tissue
. Muscle tissue
. The nervous tissue
. The epithelial tissue serves as a cover, among these are the skin and the lining of several ducts inside the body. It is divided into two general classifications: Simple Epithelium and Stratified Epithelium.
. The connective tissue supports and joins other tissues such as bone, blood and lymphatic as well as adipose tissue and reticular tissue.
. Muscle tissue consists of striated or voluntary muscles that move the skeleton and smooth muscle, such as the one that surrounds the stomach. It is divided into three types: Skeletal Muscle Tissue, Cardiac Muscle Tissue and Smooth Muscle Tissue.
. Nervous tissue is formed by nerve cells or neurons and serves to carry messages to and from various parts of the body. This tissue is present mostly in the brains and spinal cord. It has two types of tissue: The Nerve Cell and the Neuroglia.
Answer:The Law of Conservation of Mass states that mass is conserved in physical and chemical changes. Students explore this concept by taking initial masses, making predictions, and finding final masses of physical and chemical changes. Students observe water changing from ice to a liquid, a piece of cardboard being cut up, salt dissolving in water, Alka-Seltzer reacting in water, and water's physical property of cohesiveness being disrupted by soap.
