What is the charge of the outside of the DNA molecule?
Answer:
It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.)

What roles do DNA and chromosomes play in the coding of instructions for the inheritance of traits, or joe traits passed on parents to offspring?
Answer:
I really hope this helps
DNA is the vital for all living beings. even plants. it is important for inheritance, coding for proteins and the genetic instruction guide for life and its processes. DNA holds the instructions for an organisms or each cells development and reproduction and ultimately death.
Each chromosome consists of a single, very long DNA molecule, and each gene on the chromosome is a particular segment of that DNA. the instructions for forming species characteristics are carried in DNA.
In my science class we just got done learning this so it should be correct.
A student observes that a popcorn kernel has a hard coat. He places the kernel in a moist paper towel and observes it for several days. He notices that the coat splits and a small root emerges. He concludes that—
water outside the seed coat exerted a pushing force, breaking the seed coat
air inside the seed coat exerted a pushing force, breaking the seed.
water outside the seed coat exerted a pulling force, breaking the seed coat.
gravity exerted a pulling force on the stem, breaking the seed coat.

The exchange of carbon dioxide and oxygen in the alveoli of the lungs is an example of what?
C)passive transport
Answer:
Diffusion is the spontaneous movement of gases, without the use of any energy or effort by the body, between the gas in the alveoli and the blood in the capillaries in the lungs.
Raising the temperature of a gas will increase its pressure if the volume of the gas
Answer:
raising the temperature of a gas will increase its pressure if the volume of the gas. and the number of particles are constant. the temperature and volume in a closed container of gas remain constant if the number of particles of gas is increased, the gas pressure will.
Mimosa pudica is an example for ____
Answer:
Your answer is- Irritability
Irritability is the ability of an organism to respond to the external stimulus. The organism exhibit movement on receiving the stimulus from the internal or the external environment. The most common example of irritability is shown by the Mimosa plant which folds the leaflets when touched. The stimulus is passed on to the entire branch and then whole plant and all the leaflets close.

Would you design cars with different masses or equal masses? Would you design your cars with high speeds or low speeds? Use Newton's Laws of motion to support your response.
Answer:
You can actually apply the same concept, obviusly you want the cars to be the same weight, and you want your cars to be not too fast, because of the same equation F=MA if the car is faster, is because it has higher acceleration, wich results in higher impact force.

which kind of electrical charge is found on a hydrogen atom of a polar water molcule?
Answer:
he two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water's properties of attraction
