The sides or backbone of DNA is made up of what two molecules? (green in the diagram below)
Multiple choice answers
-Sugar-Nitrogen Base
-Sugar-Phosphate
-Phosphate-Nitrogen Base
-All sugar molecules
Answer: A sugar-phosphate backbone (alternating grey-dark grey) joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

As a glacier moves across the land, it pushes soil and rocks in front of it and to the sides of it. What are the hills resulting from this soil called?
Answer: They are called Moraines
Explanation: A glacier is a large body of ice originating from land that constantly moves slowly over land. It occurs in almost all parts of the world and makes up about 3/4 of fresh water all over the world.
Glaciers constantly move on land and they do this under their own weight.
As a glacier moves across land, it pushes soil and rocks in front of it and to the sides of it.
The resulting hill formed as a result of this soil movement is called a Moraine.
A moraine is sometimes referred to as a glacial till. It is an accumulation of materials (usually soil and rock) left behind by a moving glacier.

difene the meaning of the phrase entry requirements to higher education institutions and state four reasons why knowing the entry requirements is important
Answer:
1. Entry requirements to higher education are the necessary and important criteria that students intending to acquire higher education must attain before they can be granted admission.
2. Four reasons why knowing the entry requirement is important include;
a. It helps the students chose the right courses in high school.
b. It provides a standard for the universities to evaluate students objectively.
c. It ensures the admittance of students to courses suited for their capabilities and strengths.
d. It prepares students for the tasking academic environment by ensuring that they have a background knowledge of their chosen course.
Explanation:
Before students can be granted admission into schools chosen by them, they must meet certain standards to be deemed qualified by the admitting institution. Knowing these standards on time gives the students a sense of purpose and helps them to develop skills and abilities that make them qualified for admission into these schools.
It also helps the university choose the right students for different courses. Studying ahead to have the required certificates for admission helps the student gain background knowledge of their future course.

DNA is copied during the S Phase of Interphase. Why do cells copy the DNA?
Answer:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.

*lf a strand has 35% adenine, what percent will be cytosine?
Answer:15% cytosine
Explanation:We know that the sample is 35% adenine, which tells us that it is also 35% thymine. We know that cytosine and guanine pair together and will be present in equal amounts, so we can divide this final total by 2 to find our answer. The sample is 35% adenine, 35% thymine, 15% guanine, and 15% cytosine.

what is a difference between a lens and a mirror
Answer:
hi
Explanation:
The lens is a material made of glass or plastic bounded by two surfaces. ... A mirror is a reflector that is shiny from one side and reflects the light rays coming from the object to make it appear as an image to the other side. The lens is of two types viz: Concave lens and convex lens.
have a nice day
Answer:
The difference between mirror and lens lies in how light reflects when falls over their surface. When light interacts with any surface, mainly two things happen; Reflection and Refraction. The main difference between mirror and lens is that image forms by reflection, as the light falls on a mirror. In lens, the image is formed by refraction.

Explanation:
The Go' for the reaction Citrate Isocitrate is +6.64 kJmol-1 . The Go' for the reaction Isocitrate α-Ketoglutarate is -267 kJmol-1 . Calculate the Go' for the conversion of citrate to α-ketoglutarate?
Answer:
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
Explanation:
ΔG°' for Citrate is +6.64 kJmol-1
ΔG°' for Isocitrate is -267 kJmol-1
ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant
ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
