Answer:

The two potential difficulties that might have troubled Darwin’s contemporaries are:

1. Lack of transitional forms

2. Shortage of time for the varying forms to evolve.

Explanation:

Two conceivable difficulties that might have given Darwin’s contemporaries some tough work is the timeline given for evolution. This is due to the proposed age of the earth at the time of this study and the confounded numbers of individuals going through evolution.

This results from Darwin highlighting these difficulties in his essay.

Which answer choices are assumptions within the kinetic theory of matter?
kicyunya [14]

The correct options are:

  • Matter is made of small particles.
  • Matter's particles are in constant random motion or vibration
  • There is empty space between matter's particles.

Anything which has mass and occupies shape is a matter. Matter is composed of particles. The particles of matter are very small in size and they  attract each other. There is space between the particles. The particles are in continuous random motion, thus they have kinetic energy. on absorbing energy their movement increases.

A certain DNA sample is found to have a makeup consisting of 22% thymine. Use Chargaff’s rules to fill in the percentages for
Pavel [41]

Answer:

Adenine= 22%

Guanine= 28%

Cytosine = 28%

Explanation:

According to Chargaff rule, the amount of adenine in a double-stranded DNA is equal to the amount of thymine. This is due to the fact that adenine and thymine bases are complementary and form base pairs.

Likewise, the amount of guanine in a double-stranded DNA is equal to the amount of cytosine since guanine pairs with cytosine.  

Given that percentage of thymine in a DNA sample = 22%

Percentage of adenine = 22%

Total percentage of adenine and thymine = 22+ 22 = 44%

Percentage total of guanine and cytosine bases = 100-44 = 56%

Percentage of guanine base in the DNA = 56 /2 = 28%

Percentage of cytosine base in the DNA = 28%
