Which of the following statements best describes the relationship between photosynthesis and respiration?
Which chemical bonds are considered the strongest, requiring the most energy to break?
Give the mass number for an atom that has 10 protons, 10 electrons, and 11 neutrons.
Molality, m, is defined as number of moles of solute per kg of solvent. If 230 g of ethanol (C2H5OH) is added to 500 g of water, what is the molality of the solution?
Mixtures can be classified as homogenous or heterogenous and can be separated by simple means. Solutions and suspensions
The main reason why one can possibly walk barefoot on a red-hot wooden coals without burning the feet is
What process can be used on a liquid to separate its components without losing either component in the process?
How come a person with type B blood cannot donate to a person with type A blood?
Weathering is the process that changes solid rock into sediments. With weathering, rock is disintegrated. It breaks into pieces. However, rocks on the moon are not being weathered. Which of the following is the reason for this?
Each of two replicated strands of a chromosome is called a(n)
Tsunamis can be created when there is a sudden disturbance on the Earth’s crust and deformation on the sea floor. This deformation vertically displaces the overlying water and creates violent underwater disturbance. What is the main characteristic of tsunamis that differentiates it from a storm surge?
Which of these would be least likely to diffuse across the phospholipid bilayer of a cell membrane?
The bacteria that causes syphilis is
Geothermal systems produce electricity from what energy source?
If a single-celled saltwater organism is placed in freshwater, it will not be able to survive. Which statement explains why this is true?
I lack respiratory, excretory, and circulatory systems, have bilateral larva, deuterostome development, and move using a water vascular system. What am I?
Assuming that complete dominance is followed, which of the following genotypes has the same phenotype as QQRrssTt
Which of the following pairs are analogous structures?
What enzyme in saliva breaks down sugars?
A scientist performed an experiment where he knocked out the genes of a mouse cell responsible for producing the Golgi complex. Which of the following could be a consequence of the experiment to mice lacking the gene?
Vitamins help to control chemical reactions in our bodies. Without vitamins certain reactions cannot take place. We need only tiny amounts of vitamins, but without them we will suffer from deficiency diseases, like the lack of vitamin D will lead to
In a species of pea plant, white flowers were completely dominant over red flowers. Pure breeding, white flowered pea plants are crossed with pure breeding, red-flowered pea plants. What proportion of white- and red-colored plants will be produced in the F1 generation?
The circulatory system has three main components: (1) the pumping organ – the heart, (2) the circulating medium – the blood and (3) the passageways of blood – the blood vessels. Furthermore, there are three types of blood vessels: capillaries, arteries and veins. Capillaries are the site of gas exchange between the blood and the bodily tissues. Arteries carry blood away from the heart while veins carry blood towards the heart. Apart from these differences in function, these three types of blood vessels all have different morphological features. Arteries have much thicker walls than veins. What is the significance of the thicker walls for arteries?
Global climate change can be attributed to the increase in what two gases produced by human activities?
What measurement is used to quantify the destruction caused by an earthquake?
Igneous rocks originate when magma or lava cools and crystallizes or when pyroclastic materials are consolidated. The two categories of igneous rocks are plutonic rocks, which form within the earth’s crust, and volcanic rocks, which form at the surface. Volcanic rocks can usually be distinguished from plutonic rocks by
The solidification of molten rock from inside or outside the earth causes the formation of igneous rocks. These rocks are characterized by the presence of large or small crystals, depending on the rate of cooling of the rocks. Granite is an intrusive igneous rock that cooled beneath the earth’s crust, and has large crystals. What is the most probable reason for this?
A new vaccine was discovered as a treatment for a certain viral chicken disease. What should a scientist do in order to test for the effectivity of the vaccine?
In snapdragons, red flowers represent the RR genotype while white flowers represent the rr genotype. Upon breeding red and white flowers, the offsprings were neither red nor white, instead they were pink. What mode of inheritance is exhibited by the snapdragons?
The elements in group 1A of the periodic table are called:
In a flame test, the presence of copper in a solution is evident bywhat color flame?
The law which states that the amount of gas dissolved in a liquid is proportional to its partial pressure is
Which of the following scientists hypothesized that it would be possible for particles to have wave-like properties ?
The gas present in the stratosphere which filters out some of the sun's ultraviolet light and provides an effective shield against radiation damage to living things is
The arrangement of elements in the Modern Periodic Table is based on their____________
Which of the following statements is correct about an aqueous solution of an acid and of a base?
(i) Higher the pH, stronger the acid
(ii) Higher the pH, weaker the acid
(iii) Lower the pH, stronger the base
(iv) Lower the pH, weaker the base
Why does semen have alkaline bases as part of its composition?
A forensic anthropologist would most likely use which bone to determine the height of a corpse?
The respiration process during which glucose undergoes slow combustion by combining with oxygen in the cells of our body to produce energy, is a kind of:
Aluminum is used for making cooking utensils. Which of the following properties of aluminum are responsible for the same?
(i) Good thermal conductivity
(ii) Good electrical conductivity
(iii) Ductility
(iv) High melting point
Professor Geller wanted to demonstrate the role of osmosis in plant cells. He placed the cells in a solution that is hypertonic to the cells. The solution contains red microscopic dye particles. Which of the following could be a possible result of Professor Geller’s demonstration?
Gravitational potential energy is energy an object possesses because of its position in a gravitational field. Which of the following has the most gravitational potential energy?
Which electromagnetic wave has the shortest wavelength?
Which factors are involved in Gay-Lussac’s Law?

Hydrocarbons that contain a triple bond between carbon atoms are known as:
When vinegar and baking soda are mixed together, which gas is being formed?
What is the enzymatic function of restriction enzymes?
Which of the following is not a member of Kingdom Fungi?

Which of the following types of molecules are the major structural components of the cell membrane?
Which of the following sequences represents the hierarchy of biological organization from the least to the most complex level?
Species that are in the same __________ are more closely related than species that are only in the same __________.
Diatoms are one of the primary contributors to photosynthesis in the oceans. They also have a unique cell wall made up of silicate, which
 often makes them sink in the water. Although some diatoms might form colonies most are single celled. Diatoms are usually nonmotile, although in many species the gametes have flagella. Based on this information which answer is the best identification of Diatoms.
