Fossil evidence indicates that some dinosaurs had feathers. If birds are indeed descended from dinosaurs, feathers are what kind of character?.
If a strand of DNA has 48% cytosine what will the percent be for the other nitrogenous bases?
Answer:
There are 4 possible nucleotides that occur in two complementary sets. If 24% of the DNA is cytosin, the equal share has to be the complementary guanin. That makes 48% GC that leaves 52% AT, thus 26% are adenine and 26% thymine.
This calculation of course wouldn’t work if you were to look at only one DNA strand, where you’d end up with a vastly underdetermined mathematical system.

In a multicellular organism, it is cell-to-cell communication that allows the trillions of cells to coordinate activities, including during development and regeneration. The three stages of cellular communication include: reception, transduction, and response. This study determined the key steps of a cell communication pathway involved in salamander limb regeneration. After amputation of a front salamander limb, the severed axons retract within the stump and grow back along the nerve sheath. To elucidate the molecular mechanisms, the researchers set up a series of controlled experiments to determine the events in salamander limb regeneration. Drag the general cell communication steps of the regeneration experiment into the correct order.
The process of amputation will interfere with the ability of cells to communicate with each other.
What is cell to cell communication?The body of whole multicellular organisms have a lot of cells which are differentiated hence they perform diverse functions. The essence of cell differentiation is to allow different cells to perform different functions.
The question is incomplete hence we can not give here the process of cell regeneration. However, we know that the process of amputation will interfere with the ability of cells to communicate with each other.

Which of the following is a type of water pollution caused by leaded gas, The production of some pesticides, and burning garbage? Algae
dioxins
mercury
pathogens
Answer:
Dioxins.
Explanation:
Dioxin is a type of water pollution caused by leaded gas, the production of some pesticides, and burning garbage.
What do you mean by Water pollution?Water pollution may be defined as any undesirable or contaminated substance presents in water bodies that definitely harms the life of aquatic organisms.
Dioxins are highly toxic to the environment as they are responsible for causing cancer, a threat to the immune system, etc.
They are persistent organic pollutants that take a long time in the degradation process which involves breakdown into simpler substances.
Therefore, Dioxin is a type of water pollution caused by leaded gas, the production of some pesticides, and burning garbage.

What are the horticultural advantages of producing plants by cuttings rather than from seeds? Can you think of any disadvantages?
.Propagating a plant by cuttings will allow you to keep the special characteristics of that plant. Plants grown from seed will often be different from the parent plant and from each other. Propagating a new plant via cuttings avoids the difficulties of propagating by seed.
Disadvantages of propagating stem cuttings are: You will get a lack of genetic diversity and you may potentially increase Insect and Disease weakness in the new plant.

why was soil in wheat farms so much more vulnerable to erosion?
Explanation: The potential soil erosion increases if the soil has no or very little vegetative cover of plants/grass and/or crop residues. Plant and residue cover protects the soil from rain impact and splashes from it. It tends to slow down the movement of runoff water and allows excess surface water to infiltrate.

Why doesn't a gummy bear grow as much in sugar water as it does in normal water?
Answer:
In comparison to the gelatin molecules in the candy, salt or sugar ions in water are significantly smaller. Water molecules go to a location with more solute to balance things out due to osmosis. The problem is that the water is trapped inside the candy and cannot escape. Because the Gummy Bear can't get any smaller, it keeps the same size.
