Answer:
Nitrogenous bases
Explanation:
DNA is a nucleic acid molecule that acts as the genetic material of the organisms. The structure of DNA is made of two strands of nucleotides that are linked together and form a helical structure. The helical structure is known as the double-helical model with a ladder-like appearance.
The backbone of the ladder is composed of the sugar and phosphate groups at alternate positions whereas the staircase of the ladder are made of the different type of nitrogenous bases (A, G, T, C) joined by the hydrogen bond.
Thus, Nitrogenous bases is the correct answer.
Answer:
This question includes the following options to choose from:

3 point testcrosses focus on analyzing the inheritance blueprints of alleles by crossing triple heterozygotes with triple recessive homozygotes, allowing therefore to find out the distance between the alleles, and also their location order on the chromosome.
And it all comes down to the frequency of recombination, in this case such frequency between C&A is 0.02, in the same fashion that it's 0.08 between A&B; thereby the answer is A). 2
B. Modern technology allowed for larger expanses of land to become cultivated, so farming took over many natural areas that were important for wildlife
C. Machines took away jobs commonly performed by farm workers
D. Machines diminished the quality of the crops.
The correct answer is B. Modern technology allowed for larger expanses of land to become cultivated, so farming took over many natural areas that were important for wildlife.
Explanation:
In the last decades, the creation of agricultural technology has increased the efficiency of growing crops. This means now, all the process is more efficient, which leads to more products to be sold and an increase in profit. However, the possibility of large scale agriculture has caused more land is used for this purpose. This often implies natural ecosystems such as forests are destroyed and the land of these ecosystems, which is usually rich in minerals, is used for extensive agriculture. This is a negative consequence of agricultural technology as natural areas important for wildlife are taken for human profit.

A plastic bag is an everyday object that behaves like an animal cell. The bag itself represents the plasma membrane of a cell, while the items inside the bag represent the different organelles, each with its distinct function.
An everyday object that acts like an animal cell could be a plastic bag. Let me explain why. The plastic bag acts like the plasma membrane, which is the outer lining of an animal cell. It holds everything inside, much like the way a plastic bag holds whatever you put into it. Then, you have your belongings inside the bag resembling the organelles, the functional components of an animal cell. Each item in the bag has a different purpose, similar to how each organelle in a cell has a unique function.
