The inability of organisms to evolve anything that could be an advantage reflects _____.
sergey [27]

The inability of organisms to evolve anything that could be an advantage reflects "the limit of historical constraints".

<h3>What is the limit of historical constraints of evolution?</h3>

Although evolution is a powerful process that leads to

rapid changes in the characteristics of organisms, limits

to evolution arise from a lack of genetic variation, a

loss of well-adapted genotypes in populations due to

gene flow, trait interactions leading to trade-offs, and/

or the difficulty of evolving simultaneous changes in a

number of traits. This is the limit of historical constraints of evolution.

<h3>What are the factors that can cause an organism to evolve?</h3>

Four main factors lead to evolution:

(1) the potential for a species to diversify;

(2) heritable genetic variation among individuals within a species as a result of mutation and sexual reproduction;

(3) competition for scarce resources; and

(4) the spread of organisms that are better able to endure and procreate in the environment.

How do researchers prepare an intron-free copy of a eukaryotic gene for use in creating transgenic bacteria?
Tcecarenko [31]

The researchers prepare an intron-free copy of the eukaryotic gene for the use in creating the transgenic bacteria by using the reverse transcriptase to make the cDNA from the mature mRNA

The structure of the eukaryotic genes. Most of the eukaryotic genes are contain the segments of the coding sequences (exons) that interrupted by the noncoding sequences (introns). Both the exons and the introns are transcribed to yield a long and primary RNA transcript.

Eukaryotic DNA is the linear, compacted into the chromosomes by the histones, and has the telomeres at each end to protect from the deterioration. The Prokaryotes contain the circular DNA in addition to the smaller, transferable DNA plasmids. Eukaryotic cells contain the mitochondrial DNA in the addition to the nuclear DNA

A pulley system has an mechanical advantage of 10. If a mover used this pulley to lift a piano with a force of 1500 N a distance
Jlenok [28]
Answer:
(a) 145 N
(B) 40 N
(c) 10 ropes
Explanation:
Mechanical advantage, where and are input and output force respectively
Since MA is given as 10 and input force is 1450 N

Therefore, the mover must use a force of 145 N
(b)
Since also and the is given as 4 m then

(c)
Literally, we need 10 rope segments to support the piano since we utilize the mechanical advantage
