Answer: This answer is for all the questions: Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of purine and pyrimidine bases (i.e., A+G=T+C) and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
Explanation:
The pattern of criss-crossing strips of pastry on top of food is called a quadriller. It can be done with the back of a knife such as fish, scallops, etc. Examples include: meat on the grill or <span>criss-cross strips of pastry on top of a pie.</span>
<span> The goal of the pattern is to improve food presentation and make it look more interesting.</span>
Answer:
A: Unlike DNA, XNA replicates conservatively
Explanation:
<em>The replication of the DNA is </em><em>semi conservative.</em><em> This means that newly replicated double helix DNAs usually consist of one parental strands and one newly synthesized strands. The parental DNA unwinds and each strand serves as template for the synthesis of complementary strands.</em>
In the case of XNA, the two strands of parental XNA were found intact, meaning that the newly produced XNA consist of two newly synthesized strands. This thus means that the replication process is conservative.
Hence, unlike DNA replication that is semi conservative, XNA replication is conservative.
Answer:
2,855 is the size of the colony of mosquitoes after 4 days.
Explanation:
The law of uninhibited growth is given as:

= Original amount
A = Amount after time t
k = Positive constant repressing the rate of growth
We are given with:
Original population of mosquitoes = 1000
Population of mosquitoes after 1 day =1300
t = 1 day


Population size of mosquitoes after 4 days

A =? , t = 4 days

A =2,855.36 ≈ 2,855 mosquitoes
2,855 is the size of the colony of mosquitoes after 4 days.
