Answer:
Water separates polar molecules from each other by forming hydrogen bonds.
Explanation:
A polar molecule is a molecule in which the distribution of electrons between the covalently bonded atoms is not even. This means that one end of the bond is slightly more positively charged, while the other end is slightly more negatively charged.
An example of a polar molecule is a molecule of water (H2O). Substances with similar chemical characteristics dissolve in each other. This means that polar molecules will dissolve in water. The partially negative part of a water molecule will interact with the partially positive part of another polar molecule. This results in the formation of hydrogen bonds, which occur when a hydrogen atom is located between a pair of other atoms that have a high affinity for electrons.

Which statement best compares the amount of fossil fuels formed each year to the amount used each year? The amount of fossil fuels formed is exactly the same as the amount used. The amount of fossil fuels formed is approximately the same as the amount used. The amount of fossil fuels formed is much less than the amount used. The amount of fossil fuels formed is greater than the amount used.
Answers
Answer:
The amount of fossil fuels formed is much less than the amount used.
Explanation:
Fossil fuels, which include petroleum, coal, natural gas etc are an example of non-renewable sources of energy. They are termed non-renewable because they are sources that gets exhausted quickly without replenishment.
One of the characteristics of non-renewable sources of energy is that they get exhausted faster than they can be produced. Hence, regarding fossil fuels as an example of non-renewable source of energy, this means that the amount of fossil fuels formed is much less than the amount used.

What types of solid waste do you produce in your home ?what could be done to each type and what goes to the disposal site or dumpsite
Answers
Answer:
Types of solid watse we produce in your home is plastic cups, metal forks and spoons, and also glass plates. We could recycle these items, so they can become other new items when we are finished.
Solid waste are described as abandoned waste materials resulting from human and chemical activities. Solid wastes could include used plastic materials, rubber, metals, glass and other materials classed as useless.
In Homes, solid wastes usually include used plastic, shattered glass, metal objects and so on. Plastic wastes and metals could be recycled and refined to make rubber and aluminium spare parts, hence, serving as raw materials.Therefore, since solid materials take very long to Decay, hence recycling of the waste and their use in organic products are always good means of disposal.

why the answer is C not D?
Answers
Answer:
Diffusion describes the movement of particles from an area of higher to lower concentration. That is what the ink is doing when it spreads throughout the jelly. Osmosis only occurs across a semipermeable membrane.
Answer:
osmosis is movement of particles through a semipermeable membrane from the region of high concentration to region of low concentration while diffusion is the movement of particles from a region of higher concentration to a region of lower concentration.
Explanation:
here there is no semipermeable membrane hence the correct answer is diffusion.
There are only three autosomal trisomic conditions (Patau, Edward, and Down Syndrome) where a fetus will survive to birth. Why do you think this is so?
Answers
Answer:
An autosomal trisomic condition is the deviation of the chromosome number where an extra copy of the chromosome present with the chromosome pair. The three trisomic conditions are Patau - extra copy at chromosome 13, Edward - extra copy of chromosome 18, and Down Syndrome - an extra copy of chromosome 21
Children or fetuses affected by these trisomies show the least life expectancy and develop as mentally week, other than these trisomies other trisomic conditions are highly lethal so we do not see the survivors and it is due to dosage sensitivity which means that increasing or decreasing their expression levels will reduce cell viability.
A student observes the model and claims that the total mass of the reaction is conserved. Is the student's claim correct? Why or why not? A No, because the arrangement of atoms is different in the reactants and products. B Yes, because the reactants and products are made of atoms of the same elements. C Yes, because the number of atoms of each element is the same on both sides of the equation. D No, because the total number of atoms in products is greater than the total number of atoms in reactants.
Answers
C. Yes, because the number of atoms of each element is the same on both sides of the equation.
Due to the law of conservation of mass, any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Marcus is hanging a porch swing on his front porch. The first thing he has to do is attach two springs to the ceiling. Then, he fastens the
swing to the springs so that they can stretch and support the weight of the swing. Which two types of potential energy do the springs have?
A. elastic
B. gravitational
C. kinetic
D. stretched
Answers
The two types of potential energy that the springs have when Marcus hangs the porch swing on his front porch are (A)elastic potential energy and (B)gravitational potential energy.
The elastic potential energy is stored in the springs due to their deformation from their natural state. The gravitational potential energy is stored in the swing due to its height above the ground, which is determined by the position of the springs.
When Marcus attaches the springs to the ceiling, the springs are stretched and deformed from their natural state. As a result, they store elastic potential energy. This energy is proportional to the amount of deformation, which in turn is proportional to the weight of the swing and the distance the springs are stretched.
When Marcus fastens the swing to the springs, the gravitational potential energy of the swing is determined by its height above the ground. The higher the swing is from the ground, the greater its gravitational potential energy. The swing's height is determined by the length of the springs and their position relative to the ceiling
Therefore, the correct answers are A. elastic potential energy and B. gravitational potential energy.
