Across nearly seven million years, the human brain has tripled in size. The most likely the reason for the evolution of a larger brain in humans is that a larger brain allows humans to solve complex problems. Large, complex brains enable humans to process and store a lot of information and to interact with each other and with their surroundings better. The brain we now humans have is the largest and most complex of any living primate.
Answer: it’s wastes
Explanation:
All cells need these key 7 things in order to function, movement, respiration, sensitivity, growth, reproduction, excretion and nutrition.
This spells the acronym MRS GREN.
A change in the base pair sequence.
Answer:
A) cyclic and predictable
Explanation:
The graph shows changes in the water levels (in feet, ft). The water cycle consists of water that evaporates from the surface (land and sea) and subsequently returns in form of rain and/or snow. In general, water levels may be unpredictable in short term but predictable in the long term. The graph shows that this process is cyclic because it is regularly patterned and also occurs in regular intervals (therefore being predictable).
The options are:
A.
They are genetically different from the parent because they are produced by sexual reproduction.
B.
They are genetically identical to the parent because they are produced by sexual reproduction.
C. They are genetically identical to the parent because they are produced by asexual reproduction.
D.
They are genetically different from the parent because they are produced by asexual reproduction.
Answer:
The correct answer is- C. They are genetically identical to the parent because they are produced by asexual reproduction.
Explanation:
<em>E. coli </em>reproduces through binary fission in which the genetic material of cell of <em>E. coli</em> first duplicates and then the cell elongates and each of the copies of their genetic material is moved to opposite poles.
After this, the cell gets divided into two equal daughter cells. As binary fission is an asexual reproduction so there is no mixing or combination of genetic material from other <em>E.coli</em> therefore the resultant daughter cells are identical to the parent cell.
Therefore the correct answer is option c.
