DNA is a group of nucleotides that are linked together. The hydrogen bonds are responsible in making the double helix structure stable. The two strands of DNA are linked and stays in a stable shape because of the hydrogen bonds located between adenosine and thymine base pairs. Three hydrogen bonds are between cytosine and guanine.

Answer from: lilly420

Strands of DNA are composed of the sugar and phosphate portions of the nucleotides, while the middle portions are made of the nitrogenous bases. The nitrogenous bases on the two strands of DNA pair up, purine with a pyrimidine (A with T, G with C), and are held together by weak hydrogen bonds. Internal and external hydrogen bonds maintain the DNA molecule. The two strands of DNA stay together by H bonds that occur between similar nucleotide base pairs. Two hydrogen bonds occur among the adenosine and the thymine base pairs, and between the cytosine and the guanine, there are three.

Answer from: Quest

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

starchy vegetablesnon-starchy vegetables

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.

hope this !

Answer from: Quest

events in order:

1. vishnu schist

2. zoroaster granite

3. bass limestone

4. hakatar shale

5. igneous intrusion

6. shinumo quartzite

7. dox sandstone

8. tapeats limestone

9. bright angel shale

10. muav limestone

11. temple butte limestone

12. redwall limestone

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

Ascientist is investigating the effects of salinity on fish development. he places fertilized fish eggs in an aquarium that contains low salinity and observes their development. what factor would improve experimental design the most? place the fish eggs in the open ocean because that is the natural habitat include another aquarium that has normal salinity to compare to the low salinity aquarium include an aquarium that replaces salt with sugar to confirm that the effects are specific to salt grow algae with the fish eggs in order to provide adequate nutrients to the developing embryos
