Molecules that are hydrophilic (water loving) are capable of forming bonds with water and other hydrophilic molecules. They are called polar molecules. ... Small, nonpolar molecules (ex: oxygen and carbon dioxide) can pass through the lipid bilayer and do so by squeezing through the phospholipid bilayers.

Cells that are thick in the middle and tapered towards the end are called _________ cells
dalvyx [7]

Cells that are thick in the middle and tapered towards the end are called fusiform cells

<h3>What are fusiform cells?</h3>

Fusiform cells are those cells that has a spindle-like structure which means that it is thinner at the extremes and larger at the center.

A typical example of fusiform cell are the cells of the dorsal cochlear nucleus (DCN).

Therefore, cells that are thick in the middle and tapered towards the end are called fusiform cells

What additional evidence gas emerged since the publication of darwins book to support the close evolutionary relationship betwee

Implications of natural selection in shaping 99.4% nonsynonymous DNA identity between humans and chimpanzees: enlarging genus Homo. we compare approximately 90 kb of coding DNA nucleotide sequence from 97 human genes to their sequenced chimpanzee counterparts and to available sequenced gorilla, orangutan, and Old World monkey counterparts, and, on a more limited basis, to mouse. The nonsynonymous changes (functionally important), like synonymous changes (functionally much less important), show chimpanzees and humans to be most closely related, sharing 99.4% identity at nonsynonymous sites and 98.4% at synonymous sites. On a time scale, the coding DNA divergencies separate the human-chimpanzee clade from the gorilla clade at between 6 and 7 million years ago and place the most recent common ancestor of humans and chimpanzees at between 5 and 6 million years ago. The evolutionary rate of coding DNA in the catarrhine clade (Old World monkey and ape, including human) is much slower than in the lineage to mouse. Among the genes examined, 30 show evidence of positive selection during descent of catarrhines. Nonsynonymous substitutions by themselves, in this subset of positively selected genes, group humans and chimpanzees closest to each other and have chimpanzees diverge about as much from the common human-chimpanzee ancestor as humans do. This functional DNA evidence supports two previously offered taxonomic proposals: family Hominidae should include all extant apes; and genus Homo should include three extant species and two subgenera, Homo (Homo) sapiens (humankind), Homo (Pan) troglodytes (common chimpanzee), and Homo (Pan) paniscus (bonobo chimpanzee).

<span>The scientist that did NOT contribute to the idea of natural selection is <span>none of the above. The answer is letter D. Both Charles Darwin and Alfred Russel Wallace contribute to the natural selection and are biologist. Darwin hypothesized  his theory of evolution while Wallace supplied Darwin with birds for study only to found out that both have the same hypothesis regarding natural selection.

galina1969 [7]

Answer:

The incorrect conclusion is D that is finding burial sites of <em>Homo habilis </em>on different countries.

Explanation:

<em>Homo habilis</em> are called as stone age human that are appeared  between 2.1 and 1.5 million years ago and they use tools that are made up of stone which they use to kill the animals. They are called as scavengers and they didn't have any knowledge about bury the dead bodies.

<em>Homo neanderthalensis</em> are the extinct species of human that appears at about 40,000 years ago who bury the dead body but they became extinct due to competition and they did't able to adopt the modern techniques.This was the prime factor that they became extinct.
