40 POINTS -What is the purpose of cellular respiration? How does it occur?
Answer:Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.

Explanation:
Why is calcium (Ca) in group 2, period 4 on the periodic table?
Answer:
Calcium is a silvery-white, soft metal that tarnishes rapidly in air and reacts with water. Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys. Calcium is essential to all living things, particularly for the growth of healthy teeth and bones. Calcium phosphate is the main component of bone. The average human contains about 1 kilogram of calcium.

How do you think that Karl von
Frisch gathered information
about the honey bee's
behaviour?
Answer:
Karl von Frisch is best known for two major discoveries about honey bees. First, he demonstrated that honey bees have color vision, and published these findings in 191*. Second, in 193* he showed that honey bees use a dance language to communicate food locations to other bees.
Explanation:
Figure 1. Grids for the color vision test. The training color, marked with T, is blue in both cases; all other squares are shades of gray. The left box shows how the grid appears to an animal with color vision. The right box shows how the same grid may appear to an animal without color vision. The training square appears to be the same shade of gray as other squares in the grid. If the test animal cannot see in color, it will confuse the training square with other squares matching its shade of gray.
This clever test for color vision can be applied to any animal which can learn to recognize a feeding station using visual patterns.
The dance language
von Frisch observed that once one honey bee finds a feeding station, many other soon appear at the same station. This suggests that the first bee recruits other bees to the food. How might honey bees recruit help in collecting food? von Frisch¹s discovery of the dance language of the honey bee required careful determination of the correlations between movements of bees inside the hive and the locations of feeding stations. He found two types of dance. The round dance (Figure 2A) causes bees to look for food a short distance (up to about 50 meters) from the hive. The waggle dance (Figure 2B) tells bees the direction and distance to fly to find more distant food sources. Scout bees use these dances to recruit assistance in collecting food resources.

Why would it be important to understand what controls the number and types of species in an ecosystem?
•THERE’S ALSO OTHER QUESTIONS IN THE PIC (if you could answer them it would be appreciated)
Answer:The short film Some Animals Are More Equal than Others: Trophic Cascades and Keystone Species opens by asking
two fundamental questions in ecology: “What determines how many species live in a given place? Or how large
can each population grow?” The film then describes the pioneering experiments by Robert Paine and James Estes,
in the 1960s and 1970s, which started to address them. Paine’s experiments on the coast of Washington state
showed that the starfish is a keystone species, having a disproportionately large impact on its ecosystem relative
to its abundance. Estes and colleague John Palmisano discovered that the kelp forests of the North Pacific are
indirectly regulated by sea otters, which feed on sea urchins that consume kelp. The presence or absence of sea
otters causes a cascade of direct and indirect effects down the food chain, which in turn affect the structure of
the ecosystem. These early experiments inspired countless others on keystone species and trophic cascades in
ecosystems throughout the world.

Energy Change: Explain your ideas about energy changes that are taking place inside the mealworms.
Remember:
• Materials that mealworms use (arrows going in) are reactants in chemical changes
• Materials that mealworm produce (arrows going out) are products of chemical changes
When mealworms eat, chemical changes take place inside the mealworms. Chemical changes rearrange atoms. Bonds are broken in reactants. And new bonds are formed in the products.
Evidence of a chemical reaction includes a color or temperature change. Evidence of a chemical reaction can also be a gas or solid product made.

What can be said about the age of the seafloor at mid-ocean ridges?
Answer:
Scientists can determine the age of the seafloor by examining the changing magnetic field of our planet. ... While it cools down, it records the magnetic field during its formation. The two parts of the oceanic plate are pulled apart, and magnetic stripes become older as they move away from the mid-ocean ridge.

Changing the shape or morphology of the mitochondrial inner membrane can change the efficiency of mitochondrial function.
Which of the following outcomes will most likely result from a change in the shape of the mitochondrial inner membrane from a highly folded surface to a smooth, flat surface?
Since, the options have not been given the question is incomplete the complete question is as follows:
Changing the shape or morphology of the mitochondrial inner membrane can change the efficiency of mitochondrial function.
Which of the following outcomes will most likely result from a change in the shape of the mitochondrial inner membrane from a highly folded surface to a smooth, flat surface?
A. Mitochondria will become more efficient because the inner mitochondrial membrane will become more permeable to ions.
B. Mitochondria will become more efficient because the total volume of the mitochondria will increase.
C. Mitochondria will become less efficient because the inner mitochondrial membrane will become less permeable to large molecules.
D. Mitochondria will become less efficient because the surface area of the inner mitochondrial membranes will decrease.
Answer: D. Mitochondria will become less efficient because the surface area of the inner mitochondrial membranes will decrease.
Explanation:
Mitochondria is called the power house of the cell as it produces energy by the oxidation of food in the form of adenosine triphosphate or ATP. The inner mitochondrial membrane comprises of numerous folds which are called cristae which increases the surface area for the chemical reactions necessary for the production of energy. If the folding increases the surface area for energy production will decrease as the surface area for chemical reactions will decrease. Thus the efficiency of mitochondria will decrease.
If the mitochondrial inner membrane becomes flat or smooth surface then this also decreases the surface area for chemical respiration, thus in this case too the efficiency of mitochondria will decrease.
