Explanation

Epiphytes are plants that grow on other plants for physical support,

without obtaining benefits or causing harm to the host plant.

Parasites are organisms which live on or in other organisms and obtain nutrients from the host organisms.

Epiphytes depend on the host for physical support.

Explanation

The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down.

Explanation

The Earth's Moon has considerably less mass than the Earth itself.

Not only is the Moon smaller than the Earth, but it is only about 60 percent as dense as Earth.

Thus, the gravitational attraction on the Moon is much less than it is here on Earth, and a person weighs less on the Moon.

Explanation

• Heat is a form of energy associated with the motion of molecules in a substance.
• As molecules vibrate, rotate, and collide, they transfer energy from one another, resulting in the sensation of heat.

Explanation

The sun is the ultimate source of energy for our planet, providing energy through solar radiation.

This energy is then converted into various forms, such as:

• Thermal energy (heat)
• Kinetic energy (wind, water currents)
• Electrical energy (generated from solar panels)
• Chemical energy (fossil fuels, biomass)
• Biological energy (food chains, ecosystems)

Explanation

Fungi are achlorophyllous, meaning they lack chlorophyll and are unable to photosynthesize.

Instead, they are absorptive living organisms, obtaining their nutrients by breaking down and absorbing organic matter from their surroundings.

Explanation

Nuclear fusion is a process where two or more light nuclei (atomic nuclei with a small number of protons and neutrons) combine to form a single, heavier nucleus.

This process releases energy, as the resulting nucleus has a higher binding energy than the original nuclei.

Explanation

Gamma-rays have the highest penetrating power, making them suitable for treating tumors that are deep inside the body.

Gamma-rays are high-energy electromagnetic waves with frequencies higher than X-rays, and they can travel several centimeters into tissue before being absorbed.

Explanation

Homologous chromosomes are pairs of chromosomes that are similar in shape, size, and genetic content, and have the same position of the centromere.

They contain the same genes in the same order, but may have different variations of those genes (alleles).

Explanation

The female gametes (eggs) are fertilized in the fallopian tube, which is also known as the oviduct.

The fallopian tube is the narrow tube that connects the ovary to the uterus, and it's where the sperm fertilizes the egg.
