Answer:
<em>Hox </em>Gene
Explanation:
First, you're question is very vital, there are many ways in classifying along with identifying all living organisms that includes; morphological analysis, molecular systematics (studying the similarities and differences of the genetic data such in the sequences of DNA, RNA, and rRNA ), homology, cladistics, etc. based on phylogenetic tree, which the study of the evolutionary among various species.
But through it said that all living organisms shared one common ancestor. However, what makes them different from one to another is the homeotic genes that called <em>Hox </em>Genes; which specify the fate of a particular segment or region of the body, meaning the number and arrangements of the<em> Hox</em> genes varies considerably among different types of animals.
For instance, Sponges have at least one homologous to<em> Hox</em> genes, also insects have nine or more <em>Hox </em>genes resulting in multiple <em>Hox </em>genes occur in a cluster in which the genes are close to each other along a chromosome. Therefore, increases in the number of<em> Hox</em> genes have been instrumental in the evolution of many animals species with greater complexity in body structure.
Overall, more <em>Hox</em> genes, more complexity in body structure resulting in the differences of their morphological structure.
Hope that answered your question!
Answer:
A - True
Explanation:
Stanford -Binet can be define as a cognitive strength and intelligence test that can be used to carryout developmental or intellectual deficiencies or lack, in young children. this was used fervently for intelligence during early days and this was American version of test and it was used in testing the army intelligence psychologists and their military in the World War 1.
Explanation:
Epipelagic zone, the topmost at the surface of the oceans receives most of the sunlight and most penetrating light rays diffuse in this layer. The temperatures at this zone, therefore, is warmer than zones below. This zone has lowest water pressure becaue there is little water column above it.
The deeper you get into the water the penetration of sunlight decreases. This is because the rays are greatly diffused even before they get to the deepest zones. The abyssalpelagic zone virtually receives no sunlight because the rays cannot get to this zone. This zone is, therefore, pitch dark and also the coldest. The deeper you get into the ocean the higher the water pressure due to the weight of the able water column. The water pressure is, therefore, highest in the abyssalpelagic zone.

Answer:
selective breeding; biotechnology
Explanation:
Selective breeding is a type of artificial selection that consists of crossing plants/animals with desirable and heritable phenotypic traits in order to increase the frequency of such traits in progeny. Selective breeding can be considered as one of the first biotechnological techniques applied by humans. In the past, the selective breeding technique has allowed obtaining domesticated animals (e.g., dogs from wild wolves) and domesticated crops from their wild ancestors (e.g., maize from its wild ancestor teosinte).
B. Evaporation, When water is heated to its boiling point, it becomes water vapor and enters the atmosphere.
