3. (b) How does crossing over increase the variation in the gametes (and hence the offspring)?
Answer:
During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material. Gametes gain the ability to be genetically different from their neighboring gametes after crossing over occurs.

5. What is the difference between the meanings of the terms evolution
and natural selection?
Answer:
Evolution is a gradual change in the inherited traits of a population over many generations. Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes.
. If a substance changes form one phase to another, is it still the same substance?
Answer:
Yes
Explanation:
A phase change does not change the chemical make-up of a substance. Phase changes are typically temperature dependent, and change only the movement and physical arrangement of the atoms and molecules in the substance. Water, for example, is composed of two hydrogen atoms attached to an oxygen atom by covalent bonds. That stays the same whether the water is solid (ice), liquid (water), or gas (steam). The chemical structure of water does not change as it goes through the different faces. It's still water. What does change is the speed at which the molecules move and how far apart they are as a result. Water vapor consists of molecules moving quickly and at random. As temperature drops, water molecules slow down. Since water is slightly polar, hydrogen bonds form between the molecules bringing them closer together.

What are some of the differences between building the ISS to be sent out to space and building a large structure that will remain on Earth? Explore and discuss the differences and similarities in the challenges of constructing something on Earth versus something in space.
In the construction of the building of the ISS, the strength and mass of the materials used are put into consideration since there is less gravity in space.
What is space?Space is the space which is found outside the earth that is occupied and in which the planets and stars are found.
In building the ISS to be sent to space, the materials used are such that they will be able to withstand the collisions with particles found in space.
Consideration is also given to the mass since gravity is smaller in space than on earth.
However, both the ISS and buildings on earth are similar since they are built from materials.

Gabriel is performing an experiment in which he is measuring the energy and work being done by a ball rolling down a hill. Which statement best describes Gabriel’s measurements?
They will remain constant.
They will both be recorded in joules.
They will both be recorded in hertz.
They will involve compressions.
Answer:Its A
Explanation:Edge
Gabriel is performing an experiment in which he is measuring the energy and work being done by a ball rolling down a hill. The statement they will both be recorded in joules is best describes Gabriel’s measurements. Correct Option is 2.
Energy and work are both physical quantities measured in joules (J) in the International System of Units (SI). In this experiment, Gabriel is measuring the energy and work associated with the ball rolling down a hill, and both measurements will be expressed in joules. Energy represents the capacity to do work, and work is the transfer of energy that occurs when a force is applied to move an object over a distance. Both energy and work are directly related and are measured in the same unit, joules, which is a measure of energy or work.

why do plants grown with less light grow taller than the ones grown with light
Hormones released down the stem from the tip of the stem inhibit stem expansion when exposed to light. The hormones do not impede stem growth in the dark. Seeds growing in the dark rely on chemical energy stored in their cells (lipids, proteins, and carbohydrates) to fuel their growth.
