Which of the options below identify the genetic hiearchy in ascending order?
A. Chromosome, Cell, DNA, Gene and Nucleus
B. Gene, DNA, Chromosome, Nucleus and Cell
C. Cell, Nucleus, Chromosome, DNA and Gene
D. None of the above
Answer:
I hope this helps just to let you know this is what I searched just being honest :)
Explanation:
DNA
But your genes also mean that you probably look a bit like other members of your family. For example, have you been told that you have 'your mother's eyes' or 'your grandmother's nose'?
Genes influence what we look like on the outside and how we work on the inside. They contain the information our bodies need to make chemicals called proteins. Proteins form the structure of our bodies, as well playing an important role in the processes that keep us alive.
Genes are made of a chemical called DNA, which is short for 'deoxyribonucleic acid'. The DNA molecule is a double helix: that is, two long, thin strands twisted around each other like a spiral staircase.
27 DNA.gif
The DNA double helix showing base pairs
The sides are sugar and phosphate molecules. The rungs are pairs of chemicals called 'nitrogenous bases', or 'bases' for short.
There are four types of base: adenine (A), thymine (T), guanine (G) and cytosine (C). These bases link in a very specific way: A always pairs with T, and C always pairs with G.
The DNA molecule has two important properties.
It can make copies of itself. If you pull the two strands apart, each can be used to make the other one (and a new DNA molecule).
It can carry information. The order of the bases along a strand is a code - a code for making proteins.
Genes
A gene is a length of DNA that codes for a specific protein. So, for example, one gene will code for the protein insulin, which is important role in helping your body to control the amount of sugar in your blood.
Genes are the basic unit of genetics. Human beings have 20,000 to 25,000 genes. These genes account for only about 3 per cent of our DNA. The function of the remaining 97 per cent is still not clear, although scientists think it may have something to do with controlling the genes.
Chromosomes
If you took the DNA from all the cells in your body and lined it up, end to end, it would form a strand 6000 million miles long (but very, very thin)! To store this important material, DNA molecules are tightly packed around proteins called histones to make structures called chromosomes.
105-Gene-unwrapped.gif
The packaging of DNA into chromosomes
Human beings have 23 pairs of chromosomes in every cell, which makes 46 chromosomes in total. A photograph of a person's chromosomes, arranged according to size, is called a karyotype.
The sex chromosomes determine whether you are a boy (XY) or a girl (XX). The other chromosomes are called autosomes.
106-autosomes.gif
The karyotype of a male human being
The largest chromosome, chromosome 1, contains about 8000 genes. The smallest chromosome, chromosome 21, contains about 300 genes. (Chromosome 22 should be the smallest, but the scientists made a mistake when they first numbered them!).
The DNA that contains your genes is stored in your cells in a structure called the nucleus.

Which corrections should be made to describe
photosynthesis accurately? Check all that apply.
O (1) Light energy and chemical energy should be
switched.
(1) Chemical energy should be changed to
mechanical energy.
(3) Plants that contain chlorophyll should not be
included.
0 (3) Oxygen should be changed to carbon dioxide.
0 (4) Animals and plants should be switched.
Answer:
1) Light energy and chemical energy should be switched
3) Plants that contain chlorophyll should not be included
5) Animals and plants should be switch
Explanation:
Photosynthesis is a biological process through which green plants make their own food in the presence of sunlight. So, photosynthesis is a process in which Light energy is converted to chemical energy.
Plants carrying chlorophyll should not be included as their primary source is light, carbon dioxide and water.
During photosynthesis, plants make oxygen and releases it into atmosphere which is further utilized by animals or humans for metabolic activities so, photosynthesis allows the flow of energy from plants to animals.
Hence, the correct answers are " 1, 3, and 5."

Investigator Campbell is in charge of the forensics lab. One of the analysts in the lab ended up with contaminated evidence from the scene of an explosion. Looking through their work area, she sees they have a very small table next to a sink with small nylon bags stored in tight rows at room temperature. What would she advise the analyst to change about their evidence system? The evidence needs to be refrigerated quickly between analyses. The evidence can't be stored in nylon bags at all. The bags can't be kept so close together. They can’t be near the sink—it’s too humid.
Answer:
The bags can't be kept so close together.

A. Describe the role of the promoter in eukaryotic gene expression. Explain how a negative regulatory molecule could inhibit transcription at the promoter.
B. Identify TWO events that occur during RNA processing. Explain how RNA splicing increases the variation of mRNA molecules.
C. Describe the role of miRNA in gene expression.
Answer:
Explanation:
A. The role of promoter in eukariotic gene expression is It is to bind transcription factors that regulate transcription initiation. This molecule is so important because control the binding of RNA polymerase to DNA. The promoter region may be short or very long; the longer the promoter is, the more protein binding space is available. A negative regulatory molecule has the possibilty to inhibit transcription at the promoter because these molecules block the binding of RNA polymerase to the promoter region, thus not allowing the initiation of transcription, in some particular cases, the negative regulator binds to the lac repressor and will bind to the promoter in the same site where RNA polymerase would bind to.
B. Two process that occur during RNA processing are RNA splicing and 5′ capping, 3′. RNA splicing is a procces known for removing the introns from the pre-RNA and stuck back together the restant parts, exons. This process has as a goal form a mature mRNA that does not contain the intron sequences. RNA splicing has effect on variation of mRNA molecules because through a process called alternative splicing more than one mRNA can be made from the same gene.
C. Even though they are not quite the same thing miRNA and negative regulatory molecules have the same role, which is inhibit the translation and silence genes. They regulate gene expression by binding to the 3'-UTR of their target mRNAs and destabilizing the mRNA and translational silencing, repressing protein production. Even so, under specific circumstances, miRNA can activate translation or regulate transcription.
3. Which feature is commonly formed
at a plate boundary where oceanic
crust converges with continental crust?
(1) a mid ocean ridge (2) an ocean trench (3) a transform fault (4) new oceanic crust
Answer:
2) an ocean trench
Explanation:
Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.
What is Ocean Trench?Long, narrow depressions on the seafloor are known as ocean trenches. These chasms are among the deepest natural places on Earth and the deepest portions of the ocean.
Every ocean basin on the planet has ocean trenches, but the deepest ones encircle the Pacific Ocean as part of the so-called "Ring of Fire," which is also home to active volcanoes and earthquake-prone regions. Tectonic activity, which refers to the movement of the Earth's lithosphere, is what causes ocean trenches.
Ocean trenches in particular are a characteristic of convergent plate borders, which occur where two or more tectonic plates collide. In a process known as subduction, dense lithosphere melts or slides beneath less dense lithosphere along numerous convergent plate borders, forming a trench.
Therefore, Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.

Matter is anything that has mass and takes up space. It includes molecules, atoms, fundamental particles, and any substance that these particles make up. Matter can change form through physical and chemical changes, but through any of these changes matter is conserved.
In other words, matter doesn't change into a different substance in a physical change. ... Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.

what surfaces or objects on earth would reflect infrared light well?
Answer:
Infrared, sometimes called infrared light, is electromagnetic radiation with wavelengths longer than those of visible light. It is therefore invisible to the human eye.
Aside from water vapor, bodies of water on the surface of the Earth also absorb IR wavelengths well. Glass, wood, brick, stone, asphalt and paper all absorb IR radiation. While regular silver-backed mirrors reflect visible light waves, allowing you to see your reflection, they absorb infrared radiation.
