Answer:
Explanation:
The ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds.

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.

A student wants to shorten the ripening time for tomato plants. He predicts that the more water the plants receive,the faster they will ripen. To test this prediction,he grows 20 tomato plants in a garden in full sunlight that has dry soil and 20 tomato plants in a garden with a shadier location where there is greater moisture content in the soil. He then records the time it takes for fruit to develop and ripen on the plants in each garden location. State a serious error the student made with the design of the experiment. State all the constants in the problem.
Answer:
Explanation:
The major problem with this experiment is that he should have had a constant variable (in the form of the surrounding temperature) for his groups. Meaning, he should have had both groups planted in full sunlight and/or a shadier location since his prediction was on water intake by the plant and not the surrounding temperature.
The independent variable here is the type of soil (moist and dry) used while the dependent variable here is the time it took the fruit to develop and ripen on the plants in each garden location.
NOTE:
Independent variable can be described as the variable that is not dependent on any variable in the course of an experiment. It is also changed by the researcher during the course of the experiment.
Dependent variable can be described as the variable that is been tested during the course of the experiment.

The deforestation of a wooded area increases erosion, resulting in increased sediment at the bottom of a nearby river. This leads to increased flooding in the area. Which of the following terms best defines this chain of events? A) uniformitarianism B) a positive feedback loop C) a negative feedback loop D) environmental unity
Answer:
D
Explanation:
Environmental unity means that everything is connected to each other and affects each other. Here, the wooded area affects the river, which affects the flooding.
Which of the following describes an ADP molecule?
Answer:
The correct answer is -
ADP has less potential energy than ATP
ADP can be created when an ATP breaks or releases a phosphate bond.
Explanation:
ADP is adenosine diphosphate which means adenosine bound with a sugar molecule and two groups of phosphate molecules that also play an important role in cellular energy flow like ATP.
In ATP, there are three phosphates and two high energy bond that provides much energy in breaking whereas, in ADP, only one high energy bond and two phosphates present there.
When an ATP molecule breaks or releases one of its Phosphoanhydrous bonds and release energy and one of the phosphate groups, adenosine diphosphate or ADP created.

Which of the following is not a function of carbohydrates?
a structure
b genetic material
c storage
d energy
Carbohydrates are the primary source of energy in living organisms. It is a macromolecule and one of the primary nutrients required by the body.
The functions of the carbohydrates are:
Carbohydrates such as cellulose are the primary component of the cell wall of plants, bacteria, and algae. The compound provides structural support to the cells. Carbohydrates such as starch and glycogen are stored and can be used as a source of energy in time of need. Carbohydrate like glucose is the primary compound in several enzyme-catalyzed reactions to yield ATP.Thus, the correct answer is Option B.

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.

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.

•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.
