True or false. All mollusks are cemented permanently to the ground
Answer:
False
Explanation:
Mollusks are living organisms that can move around often, like mussels and clams, and oysters.
The statement "All mollusks are cemented permanently to the ground" is definitely false.
What are mollusks?Mollusks may be defined as a type of living organism that has a soft-bodied invertebrate of the phylum Mollusca, usually wholly or partly enclosed in a calcium carbonate shell secreted by a soft mantle covering the body.
According to the context of this question, mollusks also have the ability to move around their surrounding in order to facilitate their survival and interactions with other living forms. The characteristics of mollusks may include a mantle with a mantle cavity, a shell (except where lost), visceral mass, a foot, and a radula. The odontophore is in the mouth of most mollusks and it supports the radula.
Therefore, the statement "All mollusks are cemented permanently to the ground" is definitely false.

Answer:
Heat is a form of energy that moves from hot things to cold things. In other words, heat is energy that flows from objects with a high temperature. Temperature is the average kinetic energy of the particles in an object and is measured using a thermometer.
Heat can move from object to object in three ways. One way that heat flows is called conduction, which occurs when two objects are touching.
In conduction, the particles in the high temperature object are vibrating quickly compared to the low temperature object. When the particles in the high temperature object bump into the particles in the low temperature object, the low temperature object's particles begin to vibrate more quickly. Another form of heat transfer is convection, which occurs in liquids and gases. In convection, the part of the liquid or gas with high temperature is less dense than the part with low temperature so the high temperature parts rise and the low temperature parts sink.
In both conduction and convection, heat is transferred through a material. However, heat energy can also travel through empty space in a third way called radiation, which is how heat travels from the sun to the Earth.

A cell has lost the ability to release energy from glucose for the cell to use. In which of the following cell structures would this energy conversion be performed?
A nucleusnucleus
B mitochondriamitochondria
C cell membranecell membrane
D cytoplasm
A cell has lost the ability to release energy from glucose for the cell to use. Mitochondria would this energy conversion be performed. Therefore, option B is correct.
What is mitochondria ?Small structures found in the cytoplasm of a cell. Mitochondria produce the majority of the cell's energy and have their own genetic material that differs from the genetic material found in the nucleus.
The classic role of mitochondria is oxidative phosphorylation, which produces ATP by utilizing the energy released during food oxidation. In turn, ATP serves as the primary energy source for the majority of biochemical and physiological processes.
Our glucose molecules are transported by mitochondria through a process known as cellular respiration, which is essentially just a process of breaking down and converting glucose by combining oxygen with a glucose molecule.
Thus, option B is correct.

Which of the following is NOT true about the density pattern of the planets.
a
The outer planets are composed of gas o ice with dense, solid cores.
b
The terrestrial planets have molten, dense cores.
c
Gravity pulled denser materials to the center of each planet in its formation.
d
The outer planets are more dense than the terrestrial planets
Answer:
d
Explanation:
The four inner terrestrial planets are dense compared to the four outer planets. The inner planets are made up mainly of dense, solid rock. The outer planets are composed primarily of gas, so their overall density is lower. However, they are larger in size and much more massive!

Gold is a natural resource, because it occurs naturally in the environment and humans use it. Gold cannot be made from other substances, and there is a finite supply of it.
What is gold an example of?
A. a fossil fuel
B. a renewable resource
C. a nonrenewable resource
D. a natural pollut
Answer:
Answer below:
Explanation:
A nonrenewable resource
Gold is a metal formed naturally. It is not so abundant in earth and become exhausted when consumed through excavation. Hence, gold is a non-renewable source.
What are renewable resources?Renewable resources are those which never ends as we consumed and can be recycled the used amount as well. Whereas non-renewable resources are no more when we exhausted the existing amount.
Solar energy, wind energy, hydrothermal energy etc are renewable sources. Metals, minerals, nuclear power, coal, fossil fuels etc. are examples of non renewable resources.
Gold is a natural metal used have significant importance and expensive. It cannot made from other substances. Hence, once all the existing gold are taken through mining there will be no more gold. Hence, it is a non-renewable resource.
