What roles do DNA and chromosomes play in the coding of instructions for the inheritance of traits, or those traits passed from

parents to offspring
Biology

Sav [38]3 years ago

Answer:

All cells contain genetic information in the form of DNA molecules. ... Empirical evidence is required to differentiate between cause and correlation and to make claims about the role of DNA and chromosomes in coding the instructions for the characteristic traits passed from parents to offspring.

Before you tackle this essay, there are two charts attached, which will probably help you a lot more, but I still wanted to provide you with a written portion just in case. Be warned, the essay is pretty large. :) Hope this helps!

Non-living Components

There are subatomic particles like electrons, protons, and neutrons. And we could go at micro nano levels too. But we will start with atoms to explain the hierarchy.

Atoms: it’s the smallest unit of any substance in the entire world. Atom is made of neutrons, protons, and electrons. The number of electrons and protons in an atom decides what kind it is starting with Hydrogen in the periodic table which has only 1 electron and 1 proton

Molecules: it’s a group of atoms which are attracted together to bind together in strong or weak bonds.

Biomolecules: there are specific molecules which are required for living organisms called biomolecules. These help in different metabolic activities happening in a living body. Biomolecules are naturally found in the environment or are synthesized in the body.

Living components

Organelle: these are a specific section in the where biomolecules are used or synthesized. Several biochemical reactions happen in this particular space. Each organelle has its own lipid layered membranes to enclose all the reaction in them.

Cell: cells are the basic unit of life in which each has its own set of organelles in it. All the organelles have their own function and collaborate with each other taking care of the requirements of the cells.

Tissue: Cluster of the same group of cells functioning at its own. Cell to cell interaction can be seen in a tissue.

Organ: Group of tissue which cluster up to become functional and work with specific goal.

Organ systems: the organs connect together to work for a specific goal creating an organ system.

Organism: it’s an independent living system which comprises at least one cell or more.

Population: it’s a cluster of organisms of the same species associated together.

Biocoenosis or Community: 2 or more species assemble in a particular geographical area interacting each other.

Ecosystem: According to a particular environment, a group of organisms collaborate and survive as an ecosystem. This depends on the nonliving environment surrounding the organism.

Biome: it’s a community of ecosystem which survives in common environment. There are 2 major subdivisions for a biome. They are Terrestrial and Marine. But again there are a number of subdivisions for these 2 which include types like Tropical, Tundra, desert, Pelecypod, Coral etc.

Biosphere: biosphere is the collection of all ecosystem. Earth is one biosphere where you can find all the living ecosystem that we know exist.

All the living organisms we find are a small part of this hierarchy. It took a ton of research, which meant a lot of time and work to put forth this organization from a single atom to a biosphere which is the most complicated one. The hierarchy of organizations of life, help us to understand that we humans are not the dominant beings present in this world. This world belongs to much more than we can think of. Also, we need a mutual relationship with each segment of the hierarchical levels.

Here are a few charts/diagrams to help you out.

Hope this helps!

For a particular species of wolf, 55% are female, 20% hunt in medium-sized packs, and 15% are both female and hunt in medium-siz
lorasvet [3.4K]
*Given
Percent of the wolves which are female - 55%
Percent of the wolves which hunt 
     in medium-sized packs                      - 20%
Percent of the wolves which are both
     female and hunt in medium-sized
     packs                                                  - 15%


*Solution

<u>Assuming that there is a total of one hundred wolves in the species, </u>

1. Since percent (%) means "per 100" or "for every 100" then, 

a. The number of female wolves is

    (55 female wolves / 100 wolves) * 100 wolves total = 55 female wolves

b. The number of wolves that hunt in medium-sized packs is

    (20 wolves / 100 wolves) * 100 wolves total = 20 wolves

    Note that the 20 wolves is a mixture of male and female wolves. 

c. The number of female wolves that hunt in medium-sized packs is

    (15 female wolves / 100 wolves) * 100 wolves total = 15 female wolves

2. Because there is a total of 55 female wolves in the species, and 15 of these wolves hunt in medium-sized packs, then the number of female wolves that do not hunt in medium-sized packs is, 
 
    55 female wolves total - 15 female wolves hunting  = 40 female wolves not
                                                in medium-sized packs         hunting in medium
                                                                                              sized packs

3. To find the proportion, we can express the answer in terms of percent (%) or in fraction, which is usually how proportions are expressed. 

For every 100 wolves, there are 40 female wolves that do not hunt in medium-sized packs. This can be expressed as a proportion of 
 
                                       <span> <u> 40  </u>
</span>                                        100

and simplified by dividing both the numerator and denominator by 10, we get,

                                     <span><u> 40/10  </u>
</span>                                     100/10

                                       <span><u>  4   </u>
</span>                                        10

When this is expressed in percent, we multiply the fraction or proportion by 100% to get, 

                                       <span><u>  4   </u>   x    100%     = 40%
</span>                                        10

Thus, the proportion of female wolves that do not hunt in medium sized packs is 4/10 or 0.4. When expressed as percent, this is 40%.
