Answer: 1. Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
2. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species. These members of the species are more likely to reproduce and pass their genes on to their children.
Explanation:
they are formed by layers of dead cells and is produced by the formation of multiple layers of suberized periderm, cortical and phloem tissue.
D, specifically because if the parents have/had this, it is likely the patient does
From the given balanced chemical reaction,
C + O2 -> CO2
the mass ratio of the carbon and oxygen that is needed for the reaction is 12:32. Simplifying the ratio gives 3 unit mass C is to 8 unit mass O2. Given 18 g of carbon,
18 g x (32 g oxygen / 12 g carbon) = 48 grams.
For the given product, the ratio of oxygen to carbon dioxide is 32: 44.
72 g CO2 x (32 g O2 / 44 g CO2) = 52.36 grams
The first evidence of modern human traits, including increasing brain size and dependence on material culture shows up in Homo habilis. Even though they are species<span> of genus </span>Homo, they are not similar to people nowadays at all. <span>In </span>palaeoanthropology, these species were the first ones who left Africa and started to move and spread along Eurasia, which is one the main facts and characteristics of Homo habilis.
