Answer:
The stoma allows the intake of oxygen gas in photosynthesis and releases oxygen gas in respiration.
Explanation:
Through photosynthesis, leaves turn light energy into food. Through pores, or stomata, leaves “breathe” in carbon dioxide and “breathe” out oxygen. Leaves also release excess water, much like we sweat.

How could a change to the size of the algae population cause an increase in the size of the moon jelly population? (Be sure to discuss births and deaths in your answer.)
(they had no science option)
A change to the size of the algae population cause an increase in the size of the moon jelly population if there are more energy storage molecules available to the moon jellies, they can reproduce more, resulting in more births.
What is an Algal Bloom?The rapid increase or aggregation in the algae population of freshwater or marine water systems is termed an algal bloom. It is often identified by water discolouration due to the algae’s pigment.
The term algal bloom typically refers to the rapid multiplication of microscopic algae rather than macroscopic ones.
Algae are always present in natural bodies of water like oceans, lakes, and rivers, but only a few types can produce toxins.
In these algae, toxin production can be stimulated by environmental factors such as light, temperature, and nutrient levels.
Therefore, A change to the size of the algae population cause an increase in the size of the moon jelly population if there are more energy storage molecules available to the moon jellies, they can reproduce more, resulting in more births.

Sound waves travel as particles of matter collide and transfer energy.
True
False
6
Answer:
True
Explanation:
Sound waves require a medium/substance to transmit through, for example, sound waves cannot travel through the vacuum of space . The medium, water or air, itself does not move in bulk with the wave . The medium's particles carry kinetic energy from one point to another . This is when the wave transmits through its medium, the particles simply vibrate as the wave passes through. The vibrations carry the energy from one particle to the next. This means that the sound wave is carried through the medium.
*Note: Sound waves need particles to travel but light does not.

A chemist performs the same tests on two white solids, A and B. The results are shown in the table below.

Which result identifies the substances, A and B, correctly?
The melting point of a substance is characteristics to it. Hence, we can identify a compound by calculating its melting point. If the solids are pure they will give their characteristic actual melting point.
What is melting point?Melting point of a substance is the temperature at which it converts from solid state to liquid state where, the two phases are in equilibrium. Melting point is dependent upon the intermolecular forces, molar mass, temperature and presence of impurities.
Melting point of a pure substance is a characteristic feature for it. Hence, we can qualitatively test a compound using its melting point and using standard dats of melting points we can identify the substance.
Conductivity, solubility etc. are not characteristic for a substance and can be similar to other solids. Therefore, option A melting point tests helps to identify A and B.

Why might hydrogen be a wonderful fuel for the future?
Explanation:
hydrogen will join electricity as an important energy carrier since it can be made safely from renewable energy sources and is virtually non-polluting
Why might hydrogen be a wonderful fuel for the future?
Answer:
In the future, hydrogen will join electricity as an important energy carrier, since it can be made safely from renewable energy sources and is virtually non-polluting. It will also be used as a fuel for 'zero-emissions' vehicles, to heat homes and offices, to produce electricity, and to fuel aircraft.
Answer:
It can be a wonderful fuel, because unlike other sources of power generation, it produces no greenhouse gas and hence does not contribute in polluting the environment or causing global warming. However it can be a dangerous fuel as well, as it is highly flammable.
