Carbon atoms are connected in long chains by covalent bonds, which form the skeletal framework for organic molecules.
What is carbon backbone?Carbon skeleton is also known as carbon backbone. All organic compounds are made up of carbon-carbon bonds, which form a carbon skeleton or backbone. The carbon atom has special effects that allow it to form covalent bonds with up to four additional atoms, making it excellent for use as the basic structural component, or "backbone," of macromolecules. This carbon backbone is made up of chains and/or rings of carbon atoms with the addition of an element such as nitrogen or oxygen on occasion. Substituted hydrocarbons are molecules with other elements in their carbon backbone. The term carbon skeleton refers to the pattern in which carbon atoms are bonded together in a molecule, ignoring other atoms and differences between single and multiple bonds.
Therefore,
Carbon atoms are connected in long chains by covalent bonds, which form the skeletal framework for organic molecules.
These carbon skeletons can differ in several ways, including: -length -shape -number and location of double bonds -other elements covalently bonded to available sites
The diversity of carbon skeletons adds to the complexity and diversity of organic molecules..."

Sammi decides to design a model to show how the digestive and circulatory systems interact. She lines a large plastic tube with a corrugated cardboard tube. Then, she connects smaller plastic tubes to the large plastic tube. These small tubes connect to a pump. She drills small holes in the large tube so that all of the plastic tubes connect. She plans to run a green fluid representing food through the cardboard tube.
Match each part of Sammi's model to the bodily structure it represents. One bodily structure has already been labeled for you.
The digestive system takes nutrients from food and absorbs them. The circulatory system drives those nutrients to the rest of the body's cells. From the left to the right: blood vessels, heart, villi, digestive tract.
How do the digestive and circulatory systems work together?1. The digestive system is composed of different organs. Some of them mechanically break down ingested food, while others, through enzymatic action, take nutrients and let them available to be absorbed by the intestine. Villi increase the absorption area, enhancing the number of nutrients and water absorption. These are then driven to the rest of the body's cells
2. The circulatory system (composed of vessels, capillaries, veins, arteries, and the heart) takes those nutrients from the intestine walls and transports them together with the oxygen to different cells in the organisms where they are needed.

7.Type the correct part of the virus, indicated by the number 7,________9. Type the correct part of the virus, indicated by the number 9____________
The viruses have 3 main parts, the genetic material, the capsid, and some proteins.
in the image, we can see that inside we have the genetic material, and it is protected by the capsid. So the number 7 would be the genetic material.
and the number 9 would be glycoproteins that help the virus to recognize the target cell and allow the viruses to get in the cell, besides keeping the integrity of the genetic material.
Animal cells are most likely to experience damage froma. an aqueous solution.b. an isotonic solution.c. a hypotonic solution.d. a hypertonic solution.e. None of these.
Isotonic, hypertonic, and hypotonic refers to the concentration of solutes present in a solution in comparison to another solution.
In this case, they refer to a solution that surrounds animal cells.
When a solution is isotonic, it means that has the same concentration as the other, in this case, the cytosol of the cell, so there is no water flow across the cell membrane.
When the solution is hypotonic, water diffuses to the interior of the cell, which has a greater concentration of solutes, and in an animal cell this can cause the rupture of the cell, in opposition to what would happen in a plant cell, where the cell wall prevents this from happening.
And in the case of a hypertonic solution, as the concentration of solutes is greater outside the cell, the water leaves the cell.
This means that, from the options, a hypotonic solution can be more harmful to an animal cell (option C).

Which color of eyes is dominant? How do you know this?What does this mean in terms of inheritance?
The exercise tells us that 20 babies have been born in a maternity ward, and 10 of them have brown eyes, while the other 10, have blue eyes. The questions below are related to the dominant eye color, how we know it, and what it means in terms of inheritance. To this, we can answer that the dominant eye color is the brown one and that we know this due to the dominant alleles are represented with a capital letter, in this case, B, being b (for blue color) the recessive allele. In terms of inheritance, this means that if a parent with brown eyes (being BB, or Bb their genotype, but if we have that they have babies being they blue-eyed, then the genotype would be Bb), has babies with a parent that have blue eyes (being bb their genotype), the babies would have both phenotypes, as we can see in the following Punnet Square.
