The organ that produces the egg cell in the life cycle of the pine is called the ovules.
<span>The correct answer is a dichotomous key. Basically, you use the key to decide what species an organism is by looking at what traits it has, and if it doesn't have some traits you can instantly rule out a large number of species which brings you closer to your answer of what the species is that you're looking at.</span>
Answer:
Polymer of nucleotides is acidic in nature due to phosphate groups.
Explanation:
Nucleic acids are polymers of nucleotides. Each of the nucleotides contains one nitrogenous base, a pentose sugar, and a phosphate group. The polymerization of nucleotides occurs by the formation of phosphodiester bonds between them. The sugar-phosphate backbone with alternating sugar and phosphate groups is exposed to the surrounding medium while the nitrogenous bases are stacked upon each other in the interior away from the watery medium.
The phosphate groups are completely ionized and bear negative charge at the neutral pH making the polymer of nucleotide acidic in nature. The alkaline nitrogenous bases are not exposed and stacked towards the interior of the helix.
Answer:
The correct answer would be -
Punnett square is given below and on the base of the result of Punnett square, Millie should mate with <u>Denver</u> to get three different colors of puppies.
Explanation:
The question says that Millie has a genotype BB*, which is a combination or heterozygous condition of dark brown allele B and white allele B*, now cross with Denver (light brown color):
Cross 1:
B B*
B BB BB*
B* BB* B*B*
the results is : 25% dark brown, 50% light brown and 25% white.
cross 2: with Charley (white color)
B B*
B* BB* B*B*
B* BB* B*B*
there is only white and light brown puppies produced
Thus, the correct answer is - Denver.
