Answer:
Bones are organs composed of hard living tissue providing structural support to the body – it's scaffolding. It is a hard matrix of calcium salts deposited around protein fibers. Minerals make bone rigid and proteins (collagen) provide strength and elasticity. ... The outer layer of bone is called Cortical bone.
Answer:
Definition. The first metaphase of meisosis I encompasses the alignment of paired chromosomes along the center (metaphase plate) of a cell, ensuring that two complete copies of chromosomes are present in the resulting two daughter cells of meiosis I. Metaphase I follows prophase I and precedes anaphase I.

Quaternary Protein Structure
Explanation:
It's a tri structure made up of two or more separate polypeptide chains that work together to form a single functional unit. The – anti interactions and disulfide bonds that stabilize the resultant multimer are the same as in the tertiary structure.
Organisms depend on buffer that are compounds that stabilize pH by absorbing or releasing h ions. It consists of weak acids and weak bases.
The buffer is also consists of undissociated acid (HA) and the ions that are made by dissociating the acid (A-). Because of the presence of weak acids and bases and to stabilize the pH the buffer absorb or give off H+.
The nucleic acids must have positive charge that helps in formation of double helices.
Undissociated acid means when an acid dissociates to release a proton to make the solution acidic.

Answer:
are scale tree cutting can lead to deforestation, a transformation of an area from forest to terrain with little vegetation. A biosphere is the term used to describe the combination of every ecosystem on the planet. Our biosphere is Earth. The biosphere includes all living beings and their relationships. Changing temperatures can alter which organisms can survive in an ecosystem. Plants create oxygen and absorb greenhouse gases. The destruction of trees may, therefore, encourage global warming .Biotic factors pertain to living organisms and their relationships. Abiotic factors are the non-living components of the ecosystem, including sunlight, water, temperature, wind, and nutrients. Ecologists use biotic and abiotic factors to predict population changes and ecological events. A biome is the term used to describe organisms that occupy a certain area. Biomes are determined by the primary vegetation type, the climate of the area, and the geographic location. The plants and animals in a biome share common traits that are specific to the individual biome those plants and animals inhabit.
